How to Hire a Contractor for Your Small Business
How to hire an independent contractor for your small business. Classification tests, W-9, ICA, misclassification risks, and onboarding workflow.
This guide covers how to hire an independent contractor (1099 worker) for your small business so the arrangement holds up if the IRS or your state ever questions it. 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 through a personal Venmo transfer, 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. Below I walk through the full process for US small businesses without a dedicated legal team: the classification tests the IRS and the Department of Labor (DOL) use, what misclassification costs, the forms, the agreement, the audit triggers, and contractor onboarding.

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.
| Factor | Independent Contractor | W-2 Employee |
|---|---|---|
| Control over how work is done | Worker controls methods, tools, and approach | Employer directs how, when, and where work is done |
| Schedule | Contractor sets own hours | Employer sets work schedule |
| Equipment and tools | Contractor provides their own | Employer provides equipment |
| Payment | Per project, per milestone, or per deliverable | Regular payroll (hourly, salary, commission) |
| Duration | Project-based with defined end date | Ongoing, indefinite employment relationship |
| Training | Not provided (contractor already has skills) | Employer provides training on methods |
| Exclusivity | Can work for multiple clients simultaneously | Typically works exclusively for employer |
| Benefits | None from the hiring company | Health insurance, PTO, retirement, etc. |
| Tax forms | W-9 (from contractor), 1099-NEC (from employer at year end) | I-9, W-4 (from employee), W-2 (from employer at year end) |
| Tax withholding | Contractor handles own taxes | Employer 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. So when a contractor quotes you an hourly rate, compare it with about 1.4 times the wage an employee would earn for that work, not with the wage alone.
Whatever the cost comparison says, classification is determined by the actual working relationship, not by what you write in the contract. 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 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.
The DOL side 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. The proposed rule would rebuild the test around two core factors, control and the opportunity for profit or loss, as the Department's 2021 rule did. Check the current position before relying on either, and treat the 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, you can ask the IRS to rule on it. 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.

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 several directions at once: the IRS for unpaid employment taxes, the DOL for violations of the Fair Labor Standards Act (FLSA), the state for unemployment insurance and workers compensation, and potentially the worker in a private lawsuit.
Some relief is built into the tax rules. Section 3509 cuts the assessment to 1.5% of wages for the income tax and 20% of the employee FICA share. 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.
Filing every required 1099 matters for one more reason. Section 530 relief, a provision that can end the federal employment tax liability of a business for workers it did not treat as employees, 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.
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.
A contractor posting also 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.
Nick Anisimov, FirstHR founderHiring 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 core documents (W-9, ICA, and SOW) 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 the work you already owe a client, adds two checks to the process above. The first is credentials: 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 of the ABC test.
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.
| Form | What It Is | When to Collect/File | Penalty for Missing |
|---|---|---|---|
| W-9 | Contractor provides their TIN and tax classification | Before the first payment | Cannot file accurate 1099-NEC; backup withholding (24%) may apply |
| 1099-NEC | Reports payments of $2,000 or more, for payments made on or after January 1, 2026 | File by January 31 (to the IRS and the contractor) | $60 to $340 per form depending on how late; for intentional disregard, the greater of $690 per form or 10% of the amount that should have been reported |
| ICA | Independent Contractor Agreement defining the relationship | Before work begins | No legal penalty, but no documentation to defend classification |
| W-8BEN | Foreign contractor certifies their foreign tax status | Before first payment to non-US contractor | Without it, presumption rules can treat the payee as a US person subject to 24% backup withholding |
| State forms | Some states require contractor reporting (varies) | Varies by state | Varies; check your state compliance hub |
The most common mistake: paying a contractor before collecting the W-9. Once money has been sent, the contractor has far less reason to send the form back. Make W-9 collection a hard prerequisite for the first payment. The IRS forms guide sets out the forms and withholding rules for businesses that pay independent contractors.
The penalty column is a ladder rather than a flat fee. For returns due in 2027, which cover payments made in 2026, the IRS sets the charge in its yearly inflation adjustments, Revenue Procedure 2025-32: $60 per form corrected within 30 days, $130 through August 1, and $340 after that or if the form is never filed.
Intentional disregard is priced differently: the greater of $690 per form or 10% of the amounts that should have been reported, with no annual cap. Every figure is adjusted for inflation each year, so check the current row of the IRS penalty table 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.
Some states keep lower floors of their own. Florida requires a new hire report on any individual contractor paid $600 or more in a calendar year, so check the rules in your own state before you decide a contractor needs no report.
The threshold is cumulative across every payment to that contractor during the year, not a per-payment test, so keep a running total for each contractor. Remember, too, 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.
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 go beyond procedure: they are legal boundaries that protect your classification.
| Element | Employee Onboarding | Contractor Onboarding |
|---|---|---|
| Tax forms | I-9, W-4, state withholding forms | W-9 only |
| Legal agreement | Offer letter (at-will employment) | Independent Contractor Agreement + SOW |
| Benefits enrollment | Health, dental, 401k, PTO | None (contractor is self-employed) |
| Training | Role training, company culture, tools, processes | Project-specific information only (not how to do the work) |
| Equipment | Company provides laptop, phone, etc. | Contractor uses own equipment |
| System access | Full employee accounts (email, Slack, all tools) | Limited project-specific access with contractor-labeled accounts |
| Check-ins | Day 7, 30, 60, 90 reviews | Project milestone reviews only |
| Duration | Indefinite (at-will) | Defined project end date |
| Offboarding | Knowledge transfer, exit interview, COBRA | Revoke access, final invoice, 1099-NEC at year end |
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. Each of these 6 practices can invite that scrutiny, either through a directed audit or when a misclassified worker files for unemployment or workers compensation and the agency investigates.
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. By 3 to 5 concurrent contractors, the administrative overhead of tracking documents, access, payments, and year-end 1099 filing starts to justify a system.
| Contractor Volume | What You Need | Recommended Approach |
|---|---|---|
| 1-2 contractors | W-9 + ICA storage, payment tracking, 1099 filing | Google Drive folder + accounting software |
| 3-5 contractors | Add: e-signature for agreements, access tracking, document expiration alerts | Onboarding platform with e-signature + accounting software |
| 5-10 contractors | Add: contractor profiles in HR system, automated document collection, centralized access management | HR platform that handles both employees and contractors in one system |
| 10+ contractors | Add: 1099 batch filing, contractor self-service portal, compliance dashboards | Dedicated contractor management or full HR platform with contractor module |
E-signature for the ICA is worth adding even at one or two contractors, with the completed W-9 stored next to it. Printing, signing, scanning, and emailing PDF contracts is slow and error-prone, and it creates a filing nightmare.
E-signature takes 10 minutes for both parties and produces a timestamped, legally valid, automatically stored document. FirstHR handles e-signature and a document file for each contractor 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 from 1099 contractor to W-2 employee, start the employee onboarding workflow, and the I-9 and W-4 land on their task list, with the completed forms kept in their file.

Frequently Asked Questions
Do I need an EIN to hire an independent contractor?
No, hiring an independent contractor does not by itself require an EIN. You file Form 1099-NEC once you pay a contractor $2,000 or more in a calendar year, for payments made on or after January 1, 2026. The IRS asks filers for an EIN on that return, but a sole proprietor who is not otherwise required to have one uses a Social Security number instead. You need an EIN anyway once you have employees or must report backup withholding. Most small businesses already have one for payroll, banking, or tax filing purposes. If you do not, you can apply for free on the IRS website and receive the number immediately online.
How do I pay an independent contractor?
Pay a contractor when they invoice you for finished work, not on your payroll calendar. Business check, ACH bank transfer, and wire transfer all work, as do payment platforms such as PayPal or Venmo business accounts. Keep these payments out of your payroll system entirely, because a payroll record makes the relationship look like employment. Set the payment terms (net-15, net-30) in the Independent Contractor Agreement before any work starts.
What is the difference between a 1099 contractor and a W-2 employee?
A 1099 contractor is self-employed and decides how, when, and where the work gets done, while a W-2 employee works under your direction and control. The paperwork differs too: a contractor fills out a W-9 and gets a 1099-NEC from you after year end, and an employee completes Forms I-9 and W-4 and receives a W-2. Contractors pay their own taxes and arrange their own benefits. Employees have tax withheld by you and may receive employer-provided benefits. What decides the category is how the working relationship actually operates, not the title you give the worker.
Can an independent contractor work full time for one client?
Yes. Nothing in the law bars a contractor from working full-time hours for a single client. The risk lies in what usually comes with that setup: exclusivity paired with behavioral control, such as setting hours, dictating methods, or requiring the person on site, is one of the strongest signs of misclassification. Picture someone who puts in 40 hours a week for you alone, on your equipment, in your office, and on your schedule. The IRS would likely treat that person as an employee whatever the contract says, because the real arrangement, not the label, decides classification.
What is the reporting threshold for Form 1099-NEC?
It is $2,000, counted per contractor and per calendar year, a figure the One Big Beautiful Bill Act set for payments made on or after January 1, 2026. The count is a running total, not a test of each payment. Add up everything you paid one contractor during the year, and once the sum reaches the threshold you owe the IRS a 1099-NEC and the contractor a copy, both due by January 31 after the year closes. The first returns filed at the higher figure are therefore the ones due in early 2027. In the years after 2026 the amount is adjusted for inflation. Staying below it spares you the form, but the contractor must still report the income. A state can also require its own contractor report at a lower amount (Florida starts at $600 a year), so look up the rule in your state before you conclude that no form is due.
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 number or EIN. 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, a threshold that took effect for 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?
You face several separate bills, not one fine. The IRS works out the missed employment taxes with the rates in 26 U.S.C. 3509: 1.5% of wages to cover the income tax you did not withhold and 20% of the employee share of FICA, rising to 3% and 40% if you never filed the information returns the law required. You also owe the full employer half of FICA, federal and state unemployment tax, and back workers compensation premiums. If the worker brings an FLSA claim for unpaid overtime, they can recover that pay twice over, once as wages and once as liquidated damages, and their attorney fees fall on you. Willfully failing to collect the tax and pay it over is a felony under 26 U.S.C. 7202. California also charges $5,000 to $15,000 for each willful misclassification as a civil penalty.
Do I need a written contract to hire a contractor?
Federal law does not require a written contract to hire an independent contractor, but 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 it is a common move once a project role turns permanent. Close out the contractor agreement first, then put the person through the same new-hire paperwork every employee completes (I-9, W-4, and your state forms). Enroll them in payroll and benefits, switch their record in your HR system from contractor to employee, and change how you manage the work, since you can now set hours, methods, and equipment. Leave earlier invoices as contractor payments: the change runs forward from the employee start date, so you do not recast past pay as wages. An onboarding platform helps keep the transition paperwork in one place.
Is hiring a contractor cheaper than hiring an employee?
It often is on total cost, even though the hourly rate a contractor quotes looks higher. A contractor spares you the 7.65% employer share of FICA, unemployment tax, workers compensation premiums, health insurance, paid time off, and every other benefit. The Bureau of Labor Statistics Employer Costs for Employee Compensation series (June 2026) puts a number on those extras: compensation in private industry cost employers $46.89 an hour, made up of $32.82 in wages and $14.07 in benefits. That makes benefits about 30% of the total, and an employee costs roughly 1.4 times their wage once everything is loaded in. Use that multiple as your benchmark. A contractor who charges less than about 1.4 times the hourly wage you would pay an employee for the same work usually comes out cheaper, before you even count the lighter administration. On project work, a contractor also saves you the cost of keeping a full-time seat filled between projects.
