If your employer hasn't paid your final wages, Colorado law gives you specific deadlines and specific penalties — and a properly cited demand letter is how you invoke both. Here is exactly what C.R.S. § 8-4-109 requires, and what it costs your employer to ignore it.

Colorado's final paycheck deadlines at a glance

If you were fired or laid off Immediately upon discharge (C.R.S. § 8-4-109(1)(a)), with a narrow off-site-payroll exception
If you quit Next regular payday (§ 8-4-109(1)(b))
The penalty for nonpayment 14 days after written demand: automatic penalty of 2x unpaid wages or $1,000, whichever is greater — 3x or $3,000 if willful (§ 8-4-109(3)(b))

Immediate payment on discharge

Under C.R.S. § 8-4-109(1)(a), when your employer ends the relationship, every earned, vested, and determinable dollar — wages and accrued vacation — is due and payable immediately, with only a narrow exception when payroll is processed off-site. If you quit, final wages are due on the next regular payday.

The written demand is the statutory trigger

Colorado rebuilt its penalty structure effective January 1, 2023, and the new design centers on one document: your written demand. Once it's sent, § 8-4-109(3)(b) gives the employer exactly 14 days. If full payment doesn't arrive, an automatic penalty attaches: the greater of two times your unpaid wages or $1,000. If you can show the failure was willful, it's the greater of three times or $3,000 — and a second offense within five years is willful per se. On a $2,400 final paycheck, the math is $4,800 in penalties on day 15, $7,200 if willful — on top of the wages.

The 14-day safe harbor cuts both ways

The statute gives employers an out: pay everything within the 14-day window and the penalty vanishes. That's not a weakness — it's why the demand letter works. A rational employer facing “pay $2,400 now or owe $7,200 next month” pays now. Your letter just has to make the math impossible to ignore.

Get the demand right

Section 8-4-109(3)(d) has delivery requirements — the demand must state where payment can be sent, and the employer pays to the address in the demand. A letter that cites the statute, states the exact amount, computes both penalty tiers in dollars, and includes the statutory delivery details is the difference between starting the 14-day clock and writing an angry email. Claims run on a two-year statute of limitations (three for willful violations), so the clock matters twice.

What a strong Colorado demand letter looks like

An effective letter states the exact amount owed and the statutory deadline that was missed, cites C.R.S. § 8-4-109 by name, computes the penalty exposure in dollars, and sets a firm response deadline before escalation. Here's how the opening of a strong one reads:
