When the last check is legally due - and what a day late costs
A departing employee starts a clock that has nothing to do with your pay cycle. The Colorado deadlines for fired and resigning employees, the penalty for missing them, and the unused-PTO rule are below with the legal source.
Two free marketplace paths: one form brings back multiple vetted payroll providers who know they are competing for the account.
Colorado requires a final paycheck for a terminated employee Immediately upon discharge, a deadline that has nothing to do with a Denver employer's normal pay cycle and is the most common way small payrolls turn into wage claims.
Denver sets its own local minimum wage of $19.29 effective 2026-01-01, above the Colorado state floor - a local rate is a payroll setting your provider has to be told about, not one it infers.
Median household income in Denver's county (Denver County) is $92,395 per Census SAIPE 2024 - useful context for what a payroll line costs relative to what it pays.
Unused vacation is the other half of the final-paycheck question, and it is answered state by state: some states treat accrued paid time off as earned wages that must be paid out, others let your written policy decide. Getting that wrong in Denver costs far more than a year of payroll processing.
The final paycheck is the single most common payroll mistake that turns into a claim, because the deadline is set by state law and has nothing to do with your normal pay cycle. In Colorado the rule is specific - and the penalty for missing it is often calculated per day, not per dollar.

Final paycheck deadlines in Colorado
| Question | Colorado answer |
|---|---|
| Final paycheck - employee is fired | Immediately upon discharge |
| Final paycheck - employee quits | On the next regular payday |
| Penalty for a late final paycheck | If wages are not tendered within 14 days after a written demand (or after a lawsuit/administrative claim is served), the employer owes the greater of two times the unpaid wages or $1,000 |
| Unused vacation / PTO payout | must_pay; earned, vested and determinable vacation pay is 'wages' under C.R.S |
A Colorado employer's rate is three stacked pieces - base premium, an unprotestable support surcharge, and a solvency surcharge still switched on for 2026 - so even the best-rated employer pays 0.72% rather than the 0.56% base.

The termination payroll checklist, in order
| Item | Who sets the deadline | What goes wrong |
|---|---|---|
| Final wages for hours worked | State law - separate rules for fired vs quit | Paying on the next normal payday when the state required it sooner |
| Unused vacation or PTO | State law, or your written policy where the state defers | Assuming a policy overrides a state payout requirement |
| Commissions and earned bonuses | State law plus your compensation agreement | Treating earned commissions as discretionary after departure |
| Final expense reimbursements | State law in several states, otherwise policy | Leaving them for the next cycle after the employee has gone |
| Deductions from the final check | State law - many states bar deducting for damage or unreturned property | Withholding pay for an unreturned laptop where the state forbids it |
| W-2 and benefits paperwork | Federal timing rules | Losing the forwarding address before January |
Why this one costs Denver employers the most
Final-paycheck rules break the two assumptions small employers run on: that payroll happens on payday, and that a resignation and a termination are the same event. Many states set separate deadlines for each, several require payment immediately or within hours, and the penalty is often calculated per day rather than as a share of the amount owed - so a modest final check can generate a claim many times its size. Whoever runs your payroll needs the termination date the day it happens, not at the next cycle.
Before the last day
- Ask which returns the provider signs and files: Form 941 quarterly, Form 940 annually, Colorado withholding and unemployment wage reports
- Ask for sample filing confirmations from a recent client month - on-time filers produce them without hesitation
- Confirm whether the provider is a reporting agent, a certified professional employer organization, or software only - the liability differs and the IRS publishes the distinction
- Confirm the error policy in writing: who pays interest and penalties on a provider-caused late deposit, and up to what limit
- Check that the provider registers you correctly in every state where you have an employee, including new states mid-year
- Confirm data portability: full payroll history export in a usable format, at any time, at no charge
- Verify the renewal price and the notice window required to cancel, then calendar the notice date the day you sign
What this means in Denver
Cheap payroll and expensive payroll fail in the same direction: a filing that did not happen. What you are buying, at any price, is verifiable proof that deposits and returns went out on time in Colorado - if a provider cannot produce that proof on request, the discount is not a discount.

Common questions
What is state unemployment tax and why does my rate change?
Every employer pays state unemployment insurance tax on each employee's wages up to a state taxable wage base. New employers are assigned a starting rate; after enough history, the rate moves within a statutory band based on claims experience. Two identical payrolls can owe very different amounts because both the rate and the wage base are set state by state - the Colorado figures are published on this site's state page.
What is the penalty for depositing payroll taxes late?
The federal failure-to-deposit penalty runs 2% for deposits up to 5 days late, 5% for 5-15 days, 10% beyond 15 days, and 15% if the tax remains unpaid more than ten days after the IRS issues a notice. Filing Form 941 late adds a separate penalty of about 5% of the unpaid tax per month, capped near 25%.
What is the Trust Fund Recovery Penalty?
Withheld income tax and the employee share of Social Security and Medicare are held in trust for the government. When those amounts are not paid over, the IRS can assess a penalty equal to the full unpaid trust-fund amount personally against any responsible person who willfully failed to pay - an owner, officer or bookkeeper. It is one of the few business tax liabilities that reaches through a corporation or LLC to an individual.
Do I have to file W-2s and 1099s electronically?
Almost certainly yes. The threshold dropped to 10 returns: if you file 10 or more information returns of all types combined in a calendar year, they must be filed electronically. Articles still citing the old 250-return threshold are out of date. Any full-service payroll provider files electronically as standard - confirm it is included rather than billed per form.
How much does a payroll service cost for a small business?
In 2026 published pricing, payroll services charge a monthly base fee of roughly $20-$150 dollars plus $4-$15 dollars per employee per month. A ten-employee business commonly lands between $70 and $250 dollars a month before add-ons. Full outsourced processing is often quoted per person instead, at roughly $30-$100 dollars per employee per month. These are directional market ranges, not quotes.
