How to Hire Employees in Colorado: The Complete Compliance Sequence

The first time I helped a founder in Denver put someone on payroll, we counted the registrations out loud and stopped at four. A federal number from the IRS. A withholding account with the Colorado Department of Revenue. An unemployment account with the Colorado Department of Labor and Employment. A paid family leave account with the FAMLI Division. Then a workers compensation policy that has to be active before the person touches any work.

Colorado is not a hard state to hire in. It is a state with a long sequence, and the sequence has an order. Do it out of order and you end up backdating a policy, correcting a paycheck, or rewriting a job posting that already went live on three boards. Do it in order and the whole thing takes an afternoon of setup plus a few minutes per hire after that.

I built FirstHR because this kind of sequence is exactly what a small business without an HR person keeps dropping. Not because the rules are unknowable, but because the calendar reminder never got set. Below is the full Colorado sequence, step by step, with the deadline and the exposure attached to each one, verified against the state agency that actually enforces it.

The Colorado Hiring Sequence at a Glance

Every item below is a legal obligation with a named enforcing agency and a stated consequence. Six of them happen before you have a candidate, five registrations plus the posting itself. The rest attach to the offer, the start date, and the first weeks on payroll.

The remainder of this guide walks each step in the same order, with the specific Colorado details that differ from the generic advice on hiring your first employee.

Step 1: Get Your Federal Employer Identification Number

Start with the federal Employer Identification Number, because every Colorado registration that follows will ask for it. The EIN is how the IRS identifies your business on employment tax returns and deposits. Apply through the IRS online application and the number is issued at the end of the session.

If you formed an LLC or corporation and already hold an EIN, reuse it. If you have been operating as a sole proprietor and filing under your Social Security number, you need one now. Payroll tax deposits cannot be made against a personal Social Security number, and the Colorado registrations will not complete without an EIN in hand.

Step 2: Open Your Colorado State Tax Accounts

Colorado hiring requires two state tax accounts: a wage withholding account with the Department of Revenue and an unemployment insurance account with the Department of Labor and Employment. MyBizColorado handles both in a single application, which is the reason to use it rather than filing each registration separately.

The withholding account exists because Colorado taxes wages at a flat 4.40 percent. You withhold that from every paycheck and remit it on a schedule the Department of Revenue assigns based on your expected volume. There is no fee to open the account.

The unemployment account is separate. Under the Colorado Employment Security Act you become a liable employer once you pay $1,500 or more in total wages in a calendar quarter, or once you employ at least one person for any part of a day in 20 different weeks during the current or preceding calendar year. Almost every employer with a real first hire crosses one of those lines in the first year, so register when you set the start date rather than waiting to test the threshold.

New employers do not get to pick their unemployment premium rate. Colorado assigns an introductory rate by industry, built from a base rate, a support rate, and a solvency surcharge when one is in effect. Construction classifications carry their own numbers, and heavy construction is the highest of the set. Most employers move to a computed rate driven by their own claims history after the first year of activity.

Step 3: Register With the FAMLI Division

Colorado runs a state paid family and medical leave program called FAMLI, and registration is a separate step from the two tax accounts. You register through the My FAMLI+ Employer portal when you become an employer, then report wages and remit premiums quarterly through the same portal.

The 2026 premium is 0.88 percent of wages, down from 0.90 percent, applied to earnings up to the federal Social Security wage cap of $184,500 for 2026. The premium splits evenly, so the employee share is 0.44 percent. Employers below the FAMLI headcount threshold are relieved of the employer half but must still withhold and remit the employee half. That distinction is where first-time employers get caught: relief from the employer share is not an exemption from the program.

The portal also asks you to declare your employee count during registration and to refresh it every year by February 28. If you skip the annual update, the FAMLI Division assumes you are above the threshold and bills you for the full premium for that year.

Step 4: Put Workers Compensation in Force Before the Start Date

Colorado requires workers compensation insurance from the first employee, with no small employer exemption and no opt-out. The rule covers part-time staff, seasonal staff, and family members carried on payroll. Coverage has to be active before the employee performs work, not on the same day and not shortly after.

The Division of Workers Compensation enforces this with real numbers. An employer operating without coverage can be fined up to $500 for every day of the gap and can be ordered to stop work. If an employee is injured during an uninsured period, the employer pays the claim directly and owes an additional penalty equal to 25 percent of the benefits the worker receives.

Coverage comes from a private carrier, from Pinnacol Assurance, or through self-insurance if you meet the state financial requirements. For a first hire, a private policy or Pinnacol is the normal route, and the classification code assigned to the role drives the premium more than headcount does.

Step 5: Write a Job Posting That Meets the Disclosure Rules

Colorado is a pay transparency state, and the obligation attaches to the posting itself rather than to the interview. Under the Equal Pay for Equal Work Act, every job posting and every internal promotional notice must disclose four things before a single candidate applies.

Enforcement sits with the Division of Labor Standards and Statistics, and penalties run from $500 to $10,000 per violation. The statute counts one job opening as a single violation no matter how many boards list it, and a missed promotional notice as a separate violation of its own. The generic rules for what a job posting must contain apply on top of the Colorado-specific list.

Two more Colorado rules shape the application form itself. The Job Application Fairness Act, effective July 1, 2024, bars you from asking an applicant for age, date of birth, or dates of attendance at or graduation from a school on an initial application. You may still ask an applicant to confirm they meet a genuine legal age requirement for the role. Penalties escalate from a compliance order for a first violation to $1,000 for a second and $2,500 for each one after that.

The Chance to Compete Act, which has applied to all Colorado employers since September 1, 2021, is the state ban-the-box law. It prohibits advertising that people with a criminal history may not apply, and it prohibits asking about criminal history on the initial application. You can still run a background check later in the process under the usual federal and state rules.

Step 6: Make the Offer and Deliver the Required Notices

The offer letter is where the pay decisions become binding, so check the rate against three floors before you send it: the state minimum wage of $15.16 per hour, any higher municipal rate for the location where the work is performed, and the salary threshold that determines whether the role can be treated as exempt from overtime.

Colorado sets its own exempt salary threshold and it sits well above the federal one. The state PAY CALC Order puts the executive, administrative, and professional salary minimum at $1,111.23 per week, which is $57,784 per year, for 2026. The federal Fair Labor Standards Act floor is $684 per week, or $35,568 per year. Where the two differ you follow the one that is more generous to the employee, which in Colorado means the state number.

If the offer includes a non-compete or a customer non-solicitation clause, Colorado requires a separate written notice. Under the restrictive covenant statute a covenant is void unless the worker earns at or above the highly compensated threshold, set at $130,014 for 2026, and a customer non-solicitation clause requires 60 percent of that figure, which is $78,008.40. The notice must be delivered before a prospective worker accepts the offer, or at least 14 days before the effective date for a current employee. Failing to deliver it voids the covenant and carries a $5,000 penalty per worker.

Step 7: Complete Form I-9 by the Third Business Day

Form I-9 is federal, applies in every state, and has the tightest deadline in the whole sequence. The employee completes Section 1 no later than their first day of work. You complete Section 2 within three business days of that first day by examining original documents that the employee chooses to present from the USCIS list of acceptable documents.

You cannot tell the employee which documents to bring. Requesting a specific document, or asking for more documentation than the form requires, is a discrimination issue separate from the paperwork rules. Under the Department of Homeland Security civil penalty schedule at 8 CFR 274a.10, verification violations run from $288 to $2,861 for each individual involved.

Colorado adds nothing to this, which is itself worth knowing. The state once required an affirmation of legal work status within 20 days of hire, but House Bill 16-1114 repealed that requirement effective August 10, 2016 because it duplicated the federal form. E-Verify remains voluntary for private employers in Colorado.

Step 8: Collect the Withholding Forms Before the First Paycheck

Every Colorado employee completes the federal Form W-4, which drives both federal withholding and, by default, state withholding. Colorado does not require a separate state withholding certificate, but it publishes one: Form DR 0004, the Colorado Employee Withholding Certificate.

DR 0004 is optional for the employee and mandatory for you to honor when submitted. It exists so an employee can adjust Colorado withholding independently of the federal number, which matters for people with multiple jobs or significant non-wage income. If the employee does not submit one, you compute Colorado withholding from the W-4 using the Department of Revenue worksheet published as DR 1098.

Collect both forms before the first payroll run rather than during it. An employee who has not submitted a W-4 must be withheld at the default single rate, which almost always produces a complaint and a correction request in the second pay period. Pairing this step with the rest of your new hire paperwork in one digital packet removes the problem entirely.

Step 9: File the New Hire Report Within 20 Calendar Days

Colorado requires you to report every new hire to the Colorado State Directory of New Hires within 20 calendar days of the date of hire. Employers filing electronically transmit twice a month instead, in batches submitted no fewer than 12 and no more than 16 days apart.

The report is short: your legal name, address and federal employer identification number, plus the employee name, address, Social Security number and date of hire. The state uses it for child support enforcement and public assistance eligibility verification, which is why the deadline is enforced rather than aspirational.

A rehire counts as a new hire if the person has been off your payroll for at least 60 consecutive days, a detail that catches employers with seasonal staff. Federal law lets a state attach a civil penalty to a missed report, but Colorado has not adopted one, so no state fine follows a late filing. Treat the deadline as real anyway: the filing takes minutes, and the directory is what the state checks when a wage garnishment or child support order lands on your payroll.

Step 10: Post the Notices and Onboard Through Day 90

Colorado employers display a specific set of state notices alongside the federal ones, and they must be up before work begins. The state publishes almost all of them as free downloads, so paying a vendor for a laminated set is optional. The notice of paydays is the exception: you produce and print that one yourself.

With the compliance stack finished, the actual hire begins. The first 90 days decide whether the money you just spent on recruiting turns into a productive employee or an open requisition again. Gallup research finds that only 12 percent of employees strongly agree their organization does a great job of onboarding, which is a low enough bar that a simple structured plan puts a small business ahead of most employers competing for the same candidate.

This is the part of the sequence FirstHR was built to carry. The offer letter and every acknowledgment go out with built-in e-signature, the pre-start paperwork is collected before day one, task workflows hold the three-day I-9 deadline and the twenty-day report, and the AI onboarding wizard turns the job description into a 30-60-90 day plan instead of leaving the manager to invent one.

Colorado-Specific Rules That Change How You Employ People

Six Colorado rules differ enough from the federal baseline that they change your handbook, your payroll settings, or your scheduling. They apply from the first employee, not at some later size.

Overtime is the rule most often set up wrong in payroll software. The COMPS Order requires time and a half after 40 hours in a workweek, after 12 hours in a single day, and after 12 consecutive hours of work regardless of when the shift starts. You apply whichever calculation produces the most pay for the employee, and you do not combine them.

Break rules are equally specific. Employees get an uninterrupted, duty-free meal period of at least 30 minutes when a shift runs longer than five hours, and a paid rest period of ten minutes for every four hours worked. A meal period is unpaid only if the employee is genuinely relieved of all duty for the full 30 minutes.

Two more items belong on a first-hire checklist even though they arrive slightly later. Pay periods cannot exceed one calendar month or 30 days, whichever is longer, and payday must fall within ten days of the close of the pay period, with an itemized pay statement provided at least monthly. And when employment ends, Colorado splits the deadline: a fired employee is owed final wages immediately, or within six hours of the start of the next business day if payroll is closed, while an employee who resigns is paid on the next regular payday.

Colorado also runs a state retirement savings mandate. Employers that have been in business long enough and do not already sponsor a qualifying plan must either enroll in the state program or certify an exemption, with fines that reach $100 per eligible employee per year up to an annual cap. It does not usually bite on your first day as an employer, but it belongs on the calendar; the details are in the guide to the Colorado retirement mandate.

City Requirements: Denver, Boulder, Edgewater, and Local Payroll Taxes

Colorado permits local minimum wage ordinances, so the wage floor depends on where the work is physically performed. If your employee works in a city with its own rate, you pay that rate for those hours even if your business is registered elsewhere.

Several Colorado cities also charge an occupational privilege tax, a flat monthly head tax on employees who earn above a local threshold, with a matching employer portion. Denver charges $5.75 per month per covered employee with a $4.00 employer match once the employee earns $500 or more in a month. Aurora and Greenwood Village each charge $2.00 on the employee and $2.00 on the employer once monthly earnings reach $250. Glendale charges $5.00 on each side above $750 a month, and Sheridan charges $3.00 on each side.

These taxes are small in dollars and disproportionate in nuisance, because each city requires its own registration and its own filing schedule. If your first employee works from a home office in a city with the tax, the obligation follows the work location.

Employee or Independent Contractor: Colorado Uses Its Own Test

Colorado does not rely on the IRS common-law factors alone. Under the Employment Security Act, any individual performing services for pay is presumed to be an employee unless the hiring party proves two things: that the worker is free from control and direction in performing the service, and that the worker is customarily engaged in an independent trade, occupation, or business related to that service. The burden of proof sits with you, not with the worker.

The statute also allows a written document that creates a rebuttable presumption of an independent contractor relationship, built around nine criteria. The document does not have to satisfy every criterion to establish the presumption, but a relationship with no writing at all starts from the assumption of employment.

Getting this wrong in Colorado is expensive in two directions at once. The unemployment insurance liability unit can reclassify the worker and assess back premiums with interest and penalties, and the same facts can produce a workers compensation coverage finding for the identical period. A worker you thought was a contractor becomes an employee you were required to insure. The broader mechanics are in the comparison of an employee versus a contractor, and in the practical guide to hiring 1099 workers.

The Mistakes That Cost Colorado Small Businesses the Most

Each of these is a timing failure rather than a knowledge failure. The employer knew the rule and missed the window, which is exactly the category of error that a calendar and a checklist eliminate.

The common structure is worth naming. Most of them land in the two weeks around the start date, when the founder is simultaneously closing the hire, setting up accounts, and doing their actual job. That is the stretch to have the sequence written down rather than reconstructed from memory. The state-by-state view of paid sick leave requirements is a useful companion if you employ people outside Colorado too.
