Before you use this estimate
This model assumes a full-year resident of New Mexico, ordinary employee wages and all workdays physically in Colorado. Check exemption eligibility before treating a work-state amount of $0 as your own result. Withholding is a prepayment, not final tax liability. Other income, a move during the year, remote work and separate local taxes or credits can change the result.

How this $100,000 estimate adds up
These steps follow the selected home, work state, salary and filing status. They reconcile the model's annual liability, not the amounts withheld from your paycheck.
| Step | Colorado work state | New Mexico home state |
|---|---|---|
| Tax before the modeled other-state credit | $3,692 | $3,569 |
| Modeled other-state credit subtracted | $0 | $3,569 |
| Tax after that credit | $3,692 | $0 |
Total: $3,692 + $0 = $3,692 a year. Amounts are rounded for display. Work-state wage exemptions, when applicable, are already reflected in the first row; they are not an other-state credit.
The modeled credit is applied in New Mexico, the home state. Actual eligibility and credit limits require the state instructions. Included county components stay in these amounts; excluded local taxes and credits stay excluded. Federal income tax, payroll programs and refund eligibility are outside this reconciliation.

What to do
- Ask your employer to withhold Colorado tax. If New Mexico's tax is higher, withhold the difference for New Mexico too (or make estimated payments) to avoid an underpayment penalty.
- File the Colorado nonresident return first, then claim the credit for taxes paid to another state on your New Mexico resident return.
- Keep a record of the days you work in each state, especially if you sometimes work from home.
Frequently asked questions
Do I pay Colorado income tax if I live in New Mexico?
Yes. Colorado taxes wages earned there by nonresidents. On $100,000 that's about $3,692.
Do I have to file taxes in both New Mexico and Colorado?
Usually yes: a nonresident return in Colorado and a resident return in New Mexico, where you claim a credit for the tax paid to Colorado. File the Colorado return first.
Will I be taxed twice?
The modeled state credit reduces overlap on eligible wages; separate local taxes or sourcing differences can still leave additional tax. New Mexico credits the tax you pay Colorado, so your total is about $3,692 on $100,000, compared with $3,569 if you also worked in New Mexico. Local city or county taxes may still apply.
