How to Hire a Contractor

The complete guide for small businesses hiring independent contractors, with classification tests, required forms, and onboarding workflow

This guide covers how to hire an independent contractor (1099 worker) for your small business. If you are looking for a guide on hiring a construction or home improvement contractor, this is not the right resource.

The first contractor I hired was a freelance designer for a brand refresh project. I found her on a referral, agreed on a rate over email, sent payment via Venmo, and never collected a W-9 or signed an agreement. When tax season arrived and I needed to file a 1099-NEC, I realized I did not have her taxpayer ID. I also realized that if the IRS had audited our working arrangement, the lack of documentation would have made it very difficult to prove she was actually a contractor and not an employee I was paying off the books.

That experience taught me that hiring a contractor correctly is not complicated, but skipping the steps creates expensive problems. This guide covers the full process: how to determine if a worker qualifies as a contractor, the classification tests the IRS and DOL use, the forms you need, how to structure the agreement, what triggers audits, and how to onboard contractors properly. It is written for US small businesses with no dedicated HR or legal team.

TL;DR
Hiring a contractor takes three things small businesses skip: confirming the worker actually qualifies, collecting a W-9 before the first payment, and signing an Independent Contractor Agreement. Misclassification brings back taxes, penalties, and FLSA exposure. File Form 1099-NEC by January 31 once you pay one contractor $2,000 or more. The seven steps below run from classification through payment terms.

When to Hire a Contractor vs an Employee

The decision between contractor and employee is not about cost or preference. It is a legal classification based on the nature of the working relationship. The IRS and the Department of Labor both have tests to determine classification, and they do not always agree. When in doubt, the safest path is to classify the worker as an employee. The penalties for misclassifying an employee as a contractor are severe. There is no penalty for classifying a contractor as an employee.

FactorIndependent ContractorW-2 Employee
Control over how work is doneWorker controls methods, tools, and approachEmployer directs how, when, and where work is done
ScheduleContractor sets own hoursEmployer sets work schedule
Equipment and toolsContractor provides their ownEmployer provides equipment
PaymentPer project, per milestone, or per deliverableRegular payroll (hourly, salary, commission)
DurationProject-based with defined end dateOngoing, indefinite employment relationship
TrainingNot provided (contractor already has skills)Employer provides training on methods
ExclusivityCan work for multiple clients simultaneouslyTypically works exclusively for employer
BenefitsNone from the hiring companyHealth insurance, PTO, retirement, etc.
Tax formsW-9 (from contractor), 1099-NEC (from employer at year end)I-9, W-4 (from employee), W-2 (from employer at year end)
Tax withholdingContractor handles own taxesEmployer withholds income tax, FICA, state taxes

Cost never decides classification, but it does shape the choice once the law genuinely allows either option. According to the Bureau of Labor Statistics Employer Costs for Employee Compensation series (June 2026), private industry employers paid $46.89 an hour in total compensation, of which $32.82 was wages and $14.07 was benefits.

Benefits therefore run about 30% of the bill, which puts a fully loaded employee at roughly 1.4 times their wage rate. That ratio is the number to hold a contractor rate against, not the headline hourly figure the contractor quotes you.

How Common Contractor Work Actually Is
The Bureau of Labor Statistics Contingent Worker Supplement (July 2023) counted 11.9 million independent contractors in the United States, 7.4% of total employment, and found that 80.3% of them preferred that arrangement to a traditional job (BLS).

The critical principle: classification is determined by the actual working relationship, not by what you write in the contract. You cannot convert an employee into a contractor simply by calling them one, changing their payment method, or having them sign an agreement that says "independent contractor." If the working relationship has the characteristics of employment (you control the how, not just the what), the worker is an employee regardless of the label.

The Label Does Not Determine Classification
The IRS explicitly states that the relationship between the parties, not the label, determines classification. A signed "Independent Contractor Agreement" does not make someone a contractor if the actual working arrangement looks like employment. Calling someone a "freelancer," "consultant," or "1099 worker" does not change the legal reality. The classification tests look at how the work is actually performed, not what you call the person doing it.

The Three Classification Tests You Need to Know

Three different classification frameworks apply to independent contractors in the United States. The federal IRS test and the DOL test use different criteria and can reach different conclusions about the same worker. State tests, and in particular the ABC test used in California, Massachusetts, New Jersey, and a number of other states, are often stricter than either federal test. You need to satisfy every test that applies to you, not just one.

IRS common-law test (federal)IRS
1.Behavioral control: do you direct what work is accomplished and how it is done?
2.Financial control: do you direct the financial and business side of the job (tools, expenses, profit opportunity)?
3.Type of relationship: is there a written contract? Benefits? Permanency?
BOTTOM LINEIf you control the how, not just the what, the worker is likely an employee. The IRS says no single factor decides it and there is no magic number of factors.
DOL economic reality test (FLSA)DOL
1.Opportunity for profit or loss based on managerial skill
2.Investment by the worker and the employer
3.Degree of permanence of the relationship
4.Nature and degree of control by the employer
5.Whether the work is integral to the business of the employer
6.Skill and initiative of the worker
BOTTOM LINEWorkers who are economically dependent on the employer are employees under the FLSA. The rule this test sits in is under revision, so track the current standard before you rely on it.
ABC test (California, Massachusetts, New Jersey, and other states)State law
1.A: the worker is free from the control and direction of the hiring entity, both under the contract and in fact
2.B: the worker performs work outside the usual course of the hiring entity's business
3.C: the worker is customarily engaged in an independently established trade, occupation, or business of the same nature as the work performed
BOTTOM LINEThe worker is a contractor only if all three prongs are met, and the burden of proof sits on the business. This is the strictest test.

The DOL half of that picture is in motion. The Department published an independent contractor rule in January 2024, then told its own investigators to stop applying it in Field Assistance Bulletin 2025-1, and opened a fresh rulemaking whose comment period closed in April 2026 with no final rule since.

The published rule and the standard the agency actually enforces are therefore two different documents right now. Check the current position before you build an argument on either one, and treat the six economic reality factors as the durable part.

The practical implication for small businesses is simpler. If your state uses the ABC test, that is the test that matters most, because it is the strictest one and the burden of proving all three prongs sits on the business rather than on the worker.

Prong B is where small businesses actually fail. California states it as work that is outside the usual course of business of the hiring entity, and Massachusetts words it almost identically under chapter 149, section 148B.

New Jersey reaches the same place by a slightly different route. Its unemployment compensation law accepts work performed outside the usual course of the business or performed outside all of its places of business, and the employer still carries the burden on every prong.

A marketing agency hiring a freelance copywriter may struggle with prong B, because copywriting sits inside the usual business of the agency. The same agency hiring a freelance plumber to fix the office bathroom clearly passes it.

If you are unsure about classification, the IRS will rule on it for you. Form SS-8 asks for a formal determination of worker status, and the agency points filers to it alongside the Voluntary Classification Settlement Program. Budget the time, because a determination can take at least six months.

What worked for me
I use a 5-minute gut check before engaging any contractor. Three questions: (1) Am I hiring this person for a specific project with a defined end, or for ongoing work that never really ends? (2) Does this person have other clients, or will they work exclusively for me? (3) Am I going to tell them how to do the work, or just what I need delivered? If the answers are "ongoing, exclusive, and I will train them," that is an employee. If the answers are "project, multiple clients, and they already know how," that is a contractor. This is not a legal test, but it catches the obvious cases before I do the formal analysis.

The Real Cost of Misclassification

Misclassifying an employee as an independent contractor is one of the most expensive compliance mistakes a small business can make. The penalties come from multiple agencies simultaneously: the IRS for unpaid employment taxes, the DOL for FLSA violations, the state for unemployment insurance and workers compensation, and potentially the worker themselves in a private lawsuit.

Federal income tax not withheld1.5% of the wages paid, doubled to 3% if you did not file the required information returns26 U.S.C. 3509
FICA (Social Security and Medicare)The full employer share of 7.65% plus 20% of the employee share, doubled to 40% with no information returns26 U.S.C. 3509
FUTA (federal unemployment tax)Up to $42 per worker per year at the 0.6% net rate on the first $7,000 of wagesIRS Tax Topic 759
State unemployment insuranceBack contributions, penalties, and interest, set state by stateState law
Workers compensationBack premiums and penalties, set state by stateState law
FLSA wage violationsUnpaid minimum wage and overtime, an equal amount again in liquidated damages, plus the worker's attorney fee and costs29 U.S.C. 216
Willful failure to collect and pay over taxA felony: a fine of up to $10,000, imprisonment of up to 5 years, and the costs of prosecution26 U.S.C. 7202
Willful misclassification in California$5,000 to $15,000 for each violation, and $10,000 to $25,000 where the state shows a pattern or practiceCal. Labor Code 226.8
The Liabilities Stack Rather Than Substitute
One misclassified worker produces several bills from several agencies. The IRS assesses the unwithheld income tax and the FICA shortfall under 26 U.S.C. 3509, and both rates double if the required information returns were never filed. The state pursues unemployment contributions and workers compensation premiums on its own schedule. The worker can bring an FLSA claim for unpaid overtime that carries an equal amount again in liquidated damages plus attorney fees. A willful failure to collect and pay over the tax is a felony.

Relief exists at both ends of this. Section 3509 cuts the assessment to 1.5% of wages for the income tax and 20% of the employee FICA share, but those rates double to 3% and 40% where the required information returns were never filed, and the section is unavailable altogether for intentional disregard of the withholding rules.

The IRS also runs a Voluntary Classification Settlement Program that lets a business reclassify workers going forward with partial relief from federal employment tax. Correcting a misclassification yourself is far cheaper than having an examiner find it, and Section 530 relief is forfeited outright where the required information returns were not filed.

How to Hire an Independent Contractor: 7 Steps

The process of hiring a contractor is simpler than hiring an employee in some ways (no I-9, no tax withholding, no benefits enrollment) and more legally nuanced in others (classification risk, agreement structure, payment compliance). These 7 steps cover the complete process from initial decision through first payment.

1
Step 1: Confirm the role qualifies as contractor work
Run the classification tests before you engage anyone. Define the project scope, confirm the worker controls how the work is performed, and verify the engagement has a defined end date. If you cannot clearly pass the IRS common-law test and your state's test, hire the person as an employee.
2
Step 2: Define the project scope and write a Statement of Work
Create a SOW that describes the specific deliverable, timeline, milestones (if applicable), and acceptance criteria. This document proves the engagement is project-based. Be specific: 'Redesign the company website by August 15 with 8 pages and mobile responsiveness' not 'handle web stuff as needed.'
3
Step 3: Collect the W-9 before the first payment
Request a completed IRS Form W-9 from the contractor. This provides their legal name, business name (if applicable), tax classification (sole proprietor, LLC, corporation), and TIN (SSN or EIN). You need this information to file the 1099-NEC at year end. Never pay a contractor before receiving their W-9.
4
Step 4: Sign an Independent Contractor Agreement
The ICA is the foundational legal document. It should include: description of services, payment terms, project timeline, IP ownership, confidentiality obligations, termination conditions, and a clause affirming the independent contractor relationship. Both parties sign. Use e-signature for speed and documentation.
5
Step 5: Add NDA and IP assignment if applicable
If the contractor will access proprietary information, have them sign an NDA. If they will create intellectual property (code, designs, content, inventions), execute an IP assignment agreement. These are separate from the ICA because they serve different legal purposes and may survive termination of the contractor relationship.
6
Step 6: Provision limited access to tools and systems
Give the contractor access only to what they need for the project. Use a contractor-specific account (not a standard employee account) labeled clearly in your system. Document the access granted and the expected revocation date. This limits both security risk and the appearance of an employment relationship.
7
Step 7: Set up invoicing and payment terms
The contractor submits invoices for work completed. You pay based on the terms in the ICA (net-15, net-30, per milestone). Never run contractor payments through payroll software. Use a separate payment method (business check, ACH transfer, or a platform that generates 1099 reporting).

Step 1 is the most important and the most commonly skipped. Small businesses often start at Step 3 (collecting paperwork) without confirming that the worker actually qualifies as a contractor. If the classification is wrong, all the paperwork in the world does not protect you.

Between Step 1 and Step 2 sits a document this list does not name: the posting you use to find the contractor in the first place. A contractor job description is built around a deliverable and a term rather than a role and a salary, and it leaves out the working hours, reporting line, benefits, and company-provided equipment that belong in an employee posting. If the posting that attracted the contractor advertised a fixed schedule and a manager to report to, the SOW and ICA you sign afterward are arguing against your own words.

Step 2 produces the SOW itself. One per engagement, issued under the agreement rather than replacing it, and written so that what you are buying is a deliverable by a date rather than a person on a schedule.

NOTE: This is a sample document for general information only and is not legal or tax
advice. A SOW supports a contractor classification only when it matches how the work

What worked for me
I created a 3-document packet that every contractor signs before work begins: W-9, ICA, and NDA (if they will see proprietary information). I send all three via e-signature through FirstHR in one batch. The contractor signs everything in 10 minutes, I get completed documents stored automatically, and I have a paper trail from Day 1. Before I set this up, I was chasing documents weeks after work had already started.

Hiring Freelancers and Consultants

Hiring freelancers runs on exactly the rules above. Freelancer, consultant, and gig worker are business labels rather than tax categories, so the classification tests and the same three documents apply without modification. What differs is the shape of the work: freelance engagements tend to be shorter, more numerous, and sourced through a marketplace or a referral network.

That changes two practical things. Repeat engagements should get a fresh SOW issued under the original signed agreement, not a new agreement each time, which keeps one clean paper trail per person. And when a marketplace or a card processor moves the money, that platform reports the payments, so confirm which totals are actually yours to report before you file in January.

Hiring Subcontractors for Client Work

Hiring subcontractors, meaning contractors you engage to deliver part of work you already owe a client, adds two checks to the process above. Verify any license the trade requires before the engagement starts, and ask for a certificate of insurance showing general liability and, where the sub has a crew of their own, workers compensation coverage.

The second check is the paperwork chain. Your agreement with the sub needs to carry the same deadlines, confidentiality terms, and IP assignment you promised your own client, so you are never committed to something you cannot enforce downstream. Classification still applies too: a sub doing the work your business is known for runs straight into Prong B.

Required Forms and Deadlines

The forms required for hiring a contractor are simpler than employee paperwork (no I-9, no W-4, no state withholding), but the deadlines are strict and the penalties for missing them are real.

FormWhat It IsWhen to Collect/FilePenalty for Missing
W-9Contractor provides their TIN and tax classificationBefore the first paymentCannot file accurate 1099-NEC; backup withholding (24%) may apply
1099-NECReports payments of $2,000 or more, for payments made on or after January 1, 2026File by January 31 (to the IRS and the contractor)$60 to $340 per form depending on how late; $680 per form for intentional disregard
ICAIndependent Contractor Agreement defining the relationshipBefore work beginsNo legal penalty, but no documentation to defend classification
W-8BENForeign contractor provides their tax statusBefore first payment to non-US contractor30% withholding required without this form
State formsSome states require contractor reporting (varies)Varies by stateVaries; check your state compliance hub

The most common mistake: paying a contractor before collecting the W-9. Once money has been sent, leverage to collect the form drops significantly. Make W-9 collection a hard prerequisite for the first payment. The IRS forms guide lists all tax obligations for businesses that use independent contractors.

The penalty column is a ladder rather than a flat fee. For returns due in 2026, the latest year the IRS has published, the charge is $60 per form corrected within 30 days, $130 through August 1, and $340 after that or if the form is never filed, with $680 per form for intentional disregard and no maximum at all on that last figure. The amounts are adjusted for inflation each year, so read the current row before you price a late filing.

The 1099-NEC Reporting Threshold

The threshold is $2,000, and it applies to payments made on or after January 1, 2026 under the One Big Beautiful Bill Act. Cross it with any one contractor and you must file a 1099-NEC with the IRS and send that contractor a copy by January 31 of the following year.

Two details follow from the date. The first filings at the new figure go out in early 2027, and the amount is indexed for inflation after 2026, so it will not sit at $2,000 indefinitely. Several states also run their own lower reporting floors, which a federal threshold does nothing to raise.

The threshold is cumulative across every payment to that contractor during the year, not a per-payment test. Track running totals per contractor so you are not reconstructing twelve months of transactions in January, and remember that a contractor under the threshold still reports the income on their own return.

One category of payment is not yours to report at all. Payments made by credit card, debit card, or a third-party payment network (PayPal, Venmo business, Stripe) are reported by the processor on Form 1099-K, while direct payments by check, ACH, wire, or cash are your reporting responsibility.

Track Contractor Payments All Year
Do not wait until January to calculate whether you owe a 1099-NEC. Add a simple row to your accounting software or spreadsheet for each contractor: name, W-9 status, and cumulative payments year-to-date. When a contractor crosses $2,000, flag them for 1099 filing. This takes 30 seconds per payment and prevents the January panic of reconstructing a year of transactions.

Contractor Onboarding vs Employee Onboarding

Contractor onboarding and employee onboarding share some structural elements (access provisioning, document collection, project context) but differ in critical ways. The differences are not just procedural. They are legal boundaries that protect your classification.

ElementEmployee OnboardingContractor Onboarding
Tax formsI-9, W-4, state withholding formsW-9 only
Legal agreementOffer letter (at-will employment)Independent Contractor Agreement + SOW
Benefits enrollmentHealth, dental, 401k, PTONone (contractor is self-employed)
TrainingRole training, company culture, tools, processesProject-specific information only (not how to do the work)
EquipmentCompany provides laptop, phone, etc.Contractor uses own equipment
System accessFull employee accounts (email, Slack, all tools)Limited project-specific access with contractor-labeled accounts
Check-insDay 7, 30, 60, 90 reviewsProject milestone reviews only
DurationIndefinite (at-will)Defined project end date
OffboardingKnowledge transfer, exit interview, COBRARevoke access, final invoice, 1099-NEC at year end

The legal boundaries matter. If your contractor "onboarding" includes mandatory company culture training, required attendance at all-hands meetings, and a 90-day performance review, you have onboarded an employee, regardless of the contract language. Keep contractor onboarding focused on project scope, system access, and deliverable expectations. Nothing more.

For employee onboarding, the process includes compliance paperwork (I-9, W-4, state forms), 30-60-90 day plans, training assignments, buddy programs, and regular check-ins through the first 90 days. Contractor onboarding is deliberately lighter because a heavy onboarding process creates evidence of an employment relationship.

6 Mistakes That Trigger IRS Audits

The IRS and state agencies audit worker classification more frequently than most small business owners realize. These are the 6 behavioral patterns that most commonly trigger scrutiny, either through a directed audit or when a misclassified worker files for unemployment or workers compensation and the agency investigates.

Setting specific work hours or shifts
WHY IT IS RISKYContractors control their own schedule. If you dictate when they work (9 AM to 5 PM, Monday to Friday), that is behavioral control.
WHAT TO DO INSTEADSet deadlines for deliverables, not hours. Say 'deliver by Friday' not 'work Tuesday through Thursday.'
Providing a company email or business cards
WHY IT IS RISKYThese create the appearance of an employment relationship. A contractor with a @yourcompany.com email looks like an employee to the IRS.
WHAT TO DO INSTEADContractors use their own email and branding. If they need system access, create a clearly labeled external/contractor account.
Including contractors in staff meetings or performance reviews
WHY IT IS RISKYRegular participation in internal meetings and formal reviews signals an ongoing employment relationship, not a project engagement.
WHAT TO DO INSTEADHold project-specific meetings. Provide project feedback, not performance reviews. Keep contractor touchpoints separate from employee rituals.
Paying on a regular payroll schedule
WHY IT IS RISKYContractors invoice for completed work. Paying them bi-weekly on the same schedule as employees looks like payroll, not project payments.
WHAT TO DO INSTEADPay contractors on invoice submission, net-15 or net-30 terms. Never run contractor payments through your payroll system.
Providing training on how to do the work
WHY IT IS RISKYYou hire contractors because they already know how to do the work. Extensive training suggests the worker is not independently skilled.
WHAT TO DO INSTEADProvide what to deliver (project specs) and when. Not how. If the person needs significant training, they should probably be an employee.
Renewing contracts indefinitely without project scope changes
WHY IT IS RISKYA contractor who has worked continuously for 3 years on rolling 6-month contracts looks like a permanent employee with a misleading title.
WHAT TO DO INSTEADEach engagement should have a defined project, deliverable, and end date. If the need is ongoing, evaluate whether the role should be a W-2 position.

The pattern across all six mistakes: they blur the line between contractor and employee by adding elements of control that characterize employment. Each one individually raises questions. Two or three together create a strong case for misclassification. All six together make the case nearly impossible to defend.

The practical rule: if you would not do it to a plumber you hired to fix your office bathroom, do not do it to your marketing contractor. You do not set the plumber's hours, give them a company email, invite them to your team meetings, or pay them bi-weekly on payroll. Apply the same logic to every contractor engagement.

When to Use Contractor Management Software

The tools you need to manage contractors depend on volume. At one contractor, a folder with three documents (W-9, ICA, SOW) and a row in your accounting software is sufficient. At 5+ concurrent contractors, the administrative overhead of tracking documents, access, payments, and year-end 1099 filing justifies a system.

Contractor VolumeWhat You NeedRecommended Approach
1-2 contractorsW-9 + ICA storage, payment tracking, 1099 filingGoogle Drive folder + accounting software (QuickBooks, Xero)
3-5 contractorsAdd: e-signature for agreements, access tracking, document expiration alertsOnboarding platform with e-signature + accounting software
5-10 contractorsAdd: contractor profiles in HR system, automated document collection, centralized access managementHR platform that handles both employees and contractors in one system
10+ contractorsAdd: 1099 batch filing, contractor self-service portal, compliance dashboardsDedicated contractor management or full HR platform with contractor module

The key capability that matters from contractor number one: e-signature for the ICA and W-9. Printing, signing, scanning, and emailing PDF contracts is slow, error-prone, and creates a filing nightmare. E-signature takes 10 minutes for both parties and produces a timestamped, legally valid, automatically stored document. FirstHR handles contractor document collection and e-signature alongside employee onboarding on flat, predictable pricing, so you do not need separate tools for W-2 and 1099 workers.

The tool that most small businesses do not need: a dedicated contractor management platform built for companies running international payments and automated 1099 generation at scale. Those platforms price per contractor per month, so at a handful of US-based contractors the meter costs more than a flat-fee platform that already covers your employees.

Converting a Contractor to an Employee

Sometimes a contractor engagement evolves into a permanent need. When the "project" has been renewed three times and the contractor works 30+ hours per week exclusively for your company, it is time to have the conversion conversation. Converting a contractor to an employee is straightforward: end the contractor agreement, complete full employee onboarding paperwork (I-9, W-4, state forms), add them to payroll and benefits, and adjust the working relationship accordingly.

The conversion is forward-looking. You do not retroactively reclassify past contractor payments as wages. The employee start date is the conversion date. Document the reason for the conversion (role became permanent, scope changed, ongoing need identified) in case the classification of the prior contractor period is ever questioned.

Having one onboarding system that handles both contractors and employees makes this transition smoother. The person already has a profile in your system; you change their classification, trigger the employee onboarding workflow, and the system generates the right forms.

What worked for me
I have converted two contractors to full-time employees over the past few years. Both times, the trigger was the same: the "project" had been renewed 4 times, they were working 35+ hours per week exclusively for us, and I was setting their priorities in weekly meetings. By every classification test, they were employees. Converting them was the right legal move, and both were happy to get benefits and stability. The conversion paperwork took 30 minutes in FirstHR because they already had contractor profiles in the system.
Key Takeaways
Classification is determined by the actual working relationship, not the contract label: if you control how the work is done rather than only what is delivered, the worker is an employee whatever you call them.
Three tests apply, and the strictest one that reaches you governs: the IRS common-law test, the DOL economic reality test, and the state ABC test used in California, Massachusetts, New Jersey, and elsewhere.
Misclassification produces several simultaneous bills rather than one, from the IRS under 26 U.S.C. 3509, from the state for unemployment and workers compensation, and from the worker under the FLSA.
Three documents are non-negotiable before work begins: the W-9 for the tax ID, the Independent Contractor Agreement for the relationship, and the Statement of Work for the project. Never pay before the W-9 arrives.
File Form 1099-NEC by January 31 for any contractor you paid $2,000 or more in the calendar year, the threshold that governs payments made on or after January 1, 2026.
Contractor onboarding has to stay deliberately lighter than employee onboarding, because culture training, a company email address, performance reviews, and payroll-schedule payments all read as evidence of employment.

Frequently Asked Questions

Do I need an EIN to hire an independent contractor?

You do not need an EIN specifically to hire an independent contractor. However, you need an EIN to file 1099-NEC forms with the IRS, which is required once you pay a contractor $2,000 or more in a calendar year for payments made on or after January 1, 2026. Most small businesses already have an EIN for payroll, banking, or tax filing purposes. If you do not have one, you can apply for free on the IRS website and receive it immediately online.

How do I pay an independent contractor?

Pay contractors based on invoices they submit for completed work, not on a regular payroll schedule. Common payment methods include business check, ACH bank transfer, wire transfer, or payment platforms like PayPal or Venmo (business accounts). Never run contractor payments through your payroll system because this creates a record that looks like employment. Agree on payment terms (net-15, net-30) in the Independent Contractor Agreement before work begins.

What is the difference between a 1099 contractor and a W-2 employee?

A 1099 contractor is a self-employed worker who controls how, when, and where they perform work. A W-2 employee works under your direction and control. Key differences: contractors submit W-9 forms and receive 1099-NEC at year end; employees complete I-9 and W-4 forms and receive W-2. Contractors handle their own taxes and benefits. Employees have taxes withheld and may receive employer-provided benefits. The classification is based on the nature of the working relationship, not on what you call the worker.

Can an independent contractor work full time for one client?

There is no legal prohibition against a contractor working full-time hours for a single client. However, exclusivity combined with behavioral control (setting hours, dictating methods, requiring onsite presence) is one of the strongest indicators of misclassification. If a worker works 40 hours per week, exclusively for your company, using your equipment, at your office, on your schedule, the IRS will likely classify them as an employee regardless of what the contract says. The arrangement itself determines classification, not the label.

What is the reporting threshold for Form 1099-NEC?

The threshold is $2,000, and it applies to payments made on or after January 1, 2026 under the One Big Beautiful Bill Act. Cross it with any one contractor and you file a 1099-NEC with the IRS and send that contractor a copy by January 31 of the following year, so the first filings at the new figure go out in early 2027. The amount is indexed for inflation after 2026. Payments below the threshold still do not relieve the contractor of reporting the income. The threshold is cumulative per contractor per year rather than per payment, and several states run their own lower reporting floors, so check your state before you decide a contractor needs no form.

What forms do I need to hire a 1099 contractor?

Two forms are essential. First, collect a W-9 (Request for Taxpayer Identification Number) from the contractor before you make any payment. This gives you their legal name, business name, tax classification, and Social Security or EIN number. Second, file a 1099-NEC (Nonemployee Compensation) with the IRS by January 31 if you paid the contractor $2,000 or more during the calendar year, the threshold that governs payments made on or after January 1, 2026. Beyond tax forms, you should also have a signed Independent Contractor Agreement (ICA) that defines the scope of work, payment terms, and the independent nature of the relationship.

What happens if I misclassify an employee as a contractor?

Misclassification exposes your business to several bills at once rather than one. Under 26 U.S.C. 3509 the IRS assesses 1.5% of the wages paid for the income tax you did not withhold plus 20% of the employee share of FICA, and both figures double to 3% and 40% if you never filed the required information returns. On top of that sit the full employer share of FICA, federal and state unemployment tax, workers compensation back premiums, and any FLSA claim the worker brings for unpaid overtime, which carries an equal amount again in liquidated damages plus attorney fees. A willful failure to collect and pay over the tax is a felony under 26 U.S.C. 7202. California adds a civil penalty of $5,000 to $15,000 for each willful misclassification.

Do I need a written contract to hire a contractor?

While federal law does not require a written contract to hire an independent contractor, operating without one is extremely risky. A written Independent Contractor Agreement (ICA) establishes the independent nature of the relationship, defines project scope and deliverables, sets payment terms, assigns intellectual property rights, and protects both parties. In a misclassification audit, a well-drafted ICA that accurately reflects the working arrangement is evidence supporting contractor status. Without a written agreement, you have no documentation to support your classification decision.

Can I convert a contractor to a full-time employee?

Yes, and many growing businesses do this when a project role becomes permanent. To convert properly: end the contractor agreement, complete all employee onboarding paperwork (I-9, W-4, state forms), enroll the person in payroll and benefits, update their profile in your HR system from contractor to employee, and adjust the working relationship (you can now control hours, methods, and equipment). Do not retroactively reclassify past contractor payments as wages; the conversion applies going forward. Consider using an onboarding platform to manage the transition paperwork.

Is hiring a contractor cheaper than hiring an employee?

Contractors carry a higher headline rate but often a lower total cost. You do not pay employer FICA of 7.65%, unemployment tax, workers compensation premiums, health insurance, paid time off, or any other benefit. According to the Bureau of Labor Statistics Employer Costs for Employee Compensation series (June 2026), private industry employers paid $46.89 an hour in total compensation, of which $32.82 was wages and $14.07 was benefits, so benefits ran about 30% of the bill and a fully loaded employee costs roughly 1.4 times their wage rate. That ratio is the number to compare against: a contractor rate below about 1.4 times what you would pay an employee per hour for the same work is usually cheaper before you count the administrative difference. For project work, a contractor also removes the cost of carrying a full-time seat between projects.
