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 employer identification number (EIN) 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 except the last 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.

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 first hire crosses one of those two 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. For 2027 the combined rate is 1.70 percent for most industries and 4.06 percent for heavy construction, with no solvency surcharge.

Most employers move to a computed rate driven by their own claims history after the first year of activity. Construction-related employers usually keep the introductory rate for their first three years.

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.

From January 1, 2027, the FAMLI premium is 0.86 percent of wages (0.88 percent in 2026), applied to earnings up to the Social Security wage base of $192,300 for 2027 ($184,500 for 2026). The premium splits evenly, so the employee share deducted from wages is at most 0.43 percent.

Employers with fewer than 10 employees are relieved of the employer half but must still remit the employee half, normally by withholding it from wages. 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.

That is the whole registration layer. It happens once, and the account numbers it produces get asked for repeatedly afterwards, usually by whoever is trying to run payroll while you are somewhere else. Record them in one place as you go.

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, which covers any employer with at least one employee in Colorado, 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 Division 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.

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 under the Job Application Fairness Act escalate from a warning and a compliance order for a first violation to a fine of up to $1,000 for a second and up to $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.

All three rules land on the same document, so the cheapest way to comply is to stop writing postings from scratch. Build the disclosure block once, fill in the four items for each role, and run the pre-publication list before it goes live.

The last section of that block matters as much as the first. Notifying the Colorado employees who will regularly work with the person you hired is a separate obligation from the posting itself, and it is the one that gets forgotten in the relief of having filled the role.

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 $15.71 per hour from January 1, 2027 ($15.16 until then), 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 separate 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.

What worked for me

I now send the restrictive covenant notice as its own e-signature envelope, dated a day before the offer letter goes out. Burying it inside the employment agreement is exactly what the statute is written to prevent, and the fix costs nothing. The same envelope pattern works for the paid sick leave policy acknowledgment and the employee handbook receipt.

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 once work begins. 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 list of acceptable documents published by U.S. Citizenship and Immigration Services (USCIS).

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 the W-4, and the DR 0004 if the employee submits one, 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's name, address, Social Security number, date of birth, and date of hire. The state uses it for child support enforcement and public assistance eligibility verification, which is why it wants every report inside the 20-day window.

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.

According to Gallup (2018), only 12 percent of employees strongly agree that their organization does a great job onboarding new employees. That 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. Form I-9 and W-4 go on the new hire's first-day list as tasks, and completed forms are kept in their employee file; the forms themselves are completed outside the platform.

Task workflows hold the deadlines that follow, including 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, the state's wage and overtime 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.

The three overtime triggers are not combined: you apply whichever calculation produces the most pay for the employee.

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.

The second item is final pay, and 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.

What worked for me

The final pay rule is the one I would put on a sticky note. Colorado gives you hours, not days, when you end someone's employment, and the penalties under the wage act escalate quickly. I keep an off-cycle payment procedure written down before I ever need it, because writing it during a termination is how the deadline gets missed.

Colorado also runs a state retirement savings mandate. Employers with five or more employees that have been in business for at least two years must either enroll in the state program or, if they sponsor a qualifying plan, certify an exemption.

Fines under the mandate run $100 per employee per year, capped at $5,000 a year. The mandate does not usually bite on your first day as an employer, but it belongs on the calendar.

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.

The rates below take effect on January 1, 2027, as listed by the Division of Labor Standards and Statistics. Through December 31, 2026 the rates are $15.16 statewide, $19.29 in Denver, $18.17 in Edgewater, and $16.82 in both the city of Boulder and unincorporated Boulder County.

Several Colorado cities also charge an occupational privilege tax, a flat monthly head tax on employees who earn above a local threshold, plus an employer portion. Denver charges $5.75 per month per covered employee and $4.00 per month to the employer once the employee earns $500 or more in a month.

Greenwood Village charges $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. Aurora is often listed alongside these cities, but it repealed its version effective January 1, 2025.

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, signed by both parties, that creates a rebuttable presumption of an independent contractor relationship, built around nine criteria. The document only needs the criteria that fit the situation, not every one of them, but a relationship with no writing at all starts from the assumption of employment.

To create the independent contractor presumption, the document must also state two things in larger, bold, or underlined type: the contractor gets no unemployment benefits unless coverage comes from elsewhere, and the contractor owes their own federal and state income tax.

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 Mistakes That Cost Colorado Small Businesses the Most

Most of these are timing failures rather than knowledge failures. 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.

What worked for me

What finally fixed this for me was collapsing the whole sequence into two dated checklists: one that has to be finished before an offer goes out, and one that has to be finished by the third business day. Everything on the first list is a registration, so it happens once. Everything on the second list is per hire, so it becomes a template.
