Four hours a week inside Denver is enough to change your rate

Ask an HVAC technician who works out of a Denver shop but spends half the week on calls in Aurora and Lakewood what the minimum wage is and the honest answer is: which hours? Colorado kept local minimum wages illegal until 2019. HB19-1210 then let a local government raise its own floor by up to the greater of $1.75 or 15% a year. Four have acted.

For 2026 the statewide floor is $15.16 an hour with a $12.14 tipped cash wage. Denver pays $19.29 ($16.27 tipped), Edgewater $18.17 ($13.50 tipped) and the City of Boulder and unincorporated Boulder County share $16.82 ($13.80 tipped). Edgewater's wider tip offset comes from HB25-1208, which let localities go past the state's $3.02 tip credit.

Which floor you get follows your feet, not your mailing address. A local rate covers an employee expected to work at least four hours a week inside that jurisdiction and only for the time physically spent there. Driving through Denver toward a Lakewood job does not make those Denver hours. A four-hour service call downtown does.

Commuting in from Cheyenne, Santa Fe or Garden City

The state line works differently from a city line. Colorado has no wage reciprocity agreement with any neighbor, so a Cheyenne resident driving down to a Fort Collins job or a Santa Fe resident working a season in Durango is a nonresident with Colorado-source income. Nonresidents and part-year residents file Form 104PN with Form DR 0104: the 4.4% rate is applied first, then an apportionment percentage based on Colorado-source income decides how much of the result is actually Colorado's.

That apportionment step matters more than the rate. Two people with the same total income can owe very different Colorado amounts depending on how many working days fell inside the state.

Full-year residents pay on Colorado taxable income, which starts from federal taxable income and then takes Colorado's own additions and subtractions. Anyone required to file a federal return generally has a Colorado filing obligation as well.

One rate, one allowance and a FAMLI line most newcomers have never seen

Colorado is a flat-rate state: 4.4% of Colorado taxable income for 2026, the figure printed on the DR 0104EP estimated tax form. Payroll withholding mirrors that simplicity. The employer annualizes the period's wages, subtracts an annual withholding allowance, applies 4.4% and divides back to the pay period. Without a Colorado Form DR 0004 on file, the 2026 allowance is $11,000 for a married filing jointly or qualifying surviving spouse W-4 and $5,500 for every other status.

Two more lines sit beside the state tax. FAMLI, the paid family and medical leave premium, is 0.88% of wages up to $184,500, split evenly: 0.44% leaves the employee's check and 0.44% is the employer's cost. Federal FICA adds 6.2% for Social Security and 1.45% for Medicare. Four Colorado cities add a flat monthly occupational privilege tax.

Unemployment insurance never touches an employee's check. It is employer money only, on a 2026 wage base of $30,600. A UI deduction on the employee side of a Colorado pay statement is a mistake to dispute.

A Denver HVAC technician's biweekly check, line by line

Take an HVAC technician earning $28 an hour in Denver, 40 hours a week, paid every two weeks, filing single with a standard W-4 and no DR 0004. Here is what the site's calculator produces for one check:

Figures come from the Online Paystub Colorado paycheck calculator for 2026. Local taxes, health premiums and retirement contributions are not included.

Notice how the Colorado line stays small next to federal withholding and Social Security. The FAMLI premium shows up as its own much smaller entry rather than being folded into state tax. Because there are no brackets, the state deduction moves in a straight line with gross pay; run a different rate through the Colorado paycheck calculator and the proportion holds.

Seven things to verify in your first two weeks on a Colorado payroll

Colorado writes its pay statement rule into the Colorado Wage Act and its sick leave law reaches every employer, whatever its size. A new hire has more to check here than elsewhere.

1. The rate for each place you work. If you are expected to spend four or more hours a week inside Denver, Edgewater or Boulder, those hours must be paid at that floor.
2. Whether you want a DR 0004. Without one, the $5,500 allowance applies to every single filer.
3. FAMLI at 0.44%. The employee share is exactly half of 0.88% and stops once wages pass $184,500.
4. Sick leave accrual. Under the Healthy Families and Workplaces Act you earn one paid sick hour for every 30 hours worked, up to 48 a year, with up to 48 unused hours carrying forward. Rule 3.5.7 lets the employer print the balance on the statement.
5. The six statement items. CRS 8-4-103(4) requires gross wages for the period, itemized withholdings and deductions, net wages, the pay period dates, your name or Social Security number and the employer's name and address.
6. Pay period and payday. A period may run no longer than a calendar month or thirty days, whichever is longer. Payday falls within ten days of the period closing.
7. Separation timing. Under CRS 8-4-109, wages are due immediately when the employer ends the job, with short grace periods when payroll is not running. A resignation moves it to the next regular payday.

Provider labels vary. The codes that raise the most questions on Colorado statements are decoded in Online Paystub's pay stub abbreviations glossary.

The 2.9% that is almost never 2.9% at the register

The Colorado state sales tax rate is 2.9% in 2026. Cities, counties and special districts stack on top, so combined rates run from 2.9% to 11.2% depending on the address where the buyer takes delivery. The complication is administration: some local taxes are collected by the Department of Revenue while home-rule cities run their own systems, so one transaction can carry obligations to both.

A state exemption does not automatically apply locally. Certain food for home consumption, property bought for resale and qualifying manufacturing machinery are exempt from the state's 2.9%, yet a home-rule city can still tax them. One 2026 change: the state retailer service fee ended on January 1, 2026. Remote sellers cross the nexus line at $100,000 of Colorado retail sales. Returns are due on the 20th of the following month, monthly at $600 or more of tax a month and quarterly between $15 and $600, even when nothing was sold.

What the spring return adds back and hands back

Withholding is a prepayment. The DR 0104 return settles the real number. For 2026, anyone claiming the new federal deduction for overtime compensation must add the full amount back to Colorado taxable income, which an HVAC technician with a heavy summer should expect. Filers with federal adjusted gross income above $300,000 add back the part of their federal deduction above Colorado's limit of $1,000 single or $2,000 joint.

On the credit side, the Colorado Earned Income Tax Credit is 25% of the federal EITC for 2026 and later. A new refundable Disability Assistance Credit runs from $400 to $1,200 by income and filing status. Colorado also keeps an individual alternative minimum tax at 3.47% of alternative minimum taxable income, owed only when it exceeds regular tax.

Estimated payments are not required when net Colorado tax after credits and withholding is under $1,000. Above that, the safe harbor is the lesser of 70% of this year's liability or 100% of last year's, 110% of last year's for certain high earners, paid April 15, June 15, September 15 and January 15.
