In Colorado, your final paycheck is due immediately (or within 6 hours of the next workday if payroll is off-site) if you are fired, and next scheduled payday if you quit.
Final paycheck deadline in Colorado
What your final pay must include
Your final paycheck must include all the wages you earned through your last day. Whether it also has to include unused vacation depends on your state and your employer's policy, some states treat accrued vacation as wages that must be paid out. See Colorado PTO payout rules. If an employer misses the deadline, many states add penalties. This is general information, not legal advice.
