What to do
- Ask your employer to withhold New Mexico tax. If Colorado's tax is higher, withhold the difference for Colorado too (or make estimated payments) to avoid an underpayment penalty.
- File the New Mexico nonresident return first, then claim the credit for taxes paid to another state on your Colorado 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 New Mexico income tax if I live in Colorado?
Yes. New Mexico taxes wages earned there by nonresidents. On $100,000 that's about $3,569.
Do I have to file taxes in both Colorado and New Mexico?
Usually yes: a nonresident return in New Mexico and a resident return in Colorado, where you claim a credit for the tax paid to New Mexico. File the New Mexico return first.
Will I be taxed twice?
Not on the same state-level wages. Colorado credits the tax you pay New Mexico, so your total is about $3,692 on $100,000, compared with $3,692 if you also worked in Colorado. Local city or county taxes may still apply.
