The Colorado employer payroll tax calculator totals every employer-side tax — FICA, FUTA, Colorado SUI, and the FAMLI employer share — so you can see the fully loaded cost of hiring in Colorado, not just the headline salary.
How it works
On top of an employee’s gross wages, a Colorado employer owes:
- Employer FICA — Social Security at
6.2%up to the annual wage base, plus Medicare at1.45%on all wages. - FUTA —
0.6%effective on the first$7,000of wages after the standard 5.4% state credit, capped at$42per employee. - Colorado SUI — your assigned rate (new employers ≈
1.7%) on the first$27,200of wages for 2024. - FAMLI employer share —
0.45%of wages (employers with fewer than 10 workers owe$0).
The calculator adds these and reports the total, the effective rate on wages, and the fully loaded employee cost.
Worked example
An employee paid $55,000 per year, new-employer SUI of 1.7%, 10+ employees:
| Tax | Amount |
|---|---|
| Social Security (6.2%) | $3,410 |
| Medicare (1.45%) | $797.50 |
| FUTA (0.6% on $7,000) | $42 |
| Colorado SUI (1.7% on $27,200) | $462.40 |
| FAMLI employer (0.45%) | $247.50 |
| Total | ~$4,959 |
That is roughly a 9% add-on, so the fully loaded cost is about $59,959.
Notes and tips
- Your real SUI rate is experience-rated and set yearly — a single layoff can raise it, so use your official rate notice rather than the default.
- FUTA and SUI taxes stop once the employee crosses each wage cap, so the effective rate on high earners is lower than on the first few thousand dollars.
- Small employers (fewer than 10 workers) can toggle off the FAMLI employer share, which they are exempt from paying.
