Live in Kansas, work in Colorado
Without wage reciprocity, the work state may tax wages earned there. Your home state generally offers a limited credit for eligible tax paid on the same income. Filing requirements, credit limits and local taxes need a separate check.

Before you use this estimate
This model assumes a full-year resident of Kansas, 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.

Tax guide and official sources: live in Kansas, work in Colorado
Official agency starting points: Kansas tax agency (opens in new tab) · Colorado tax agency (opens in new tab). These directory links identify the selected states' agencies, not your filing obligations. Check their individual-tax guidance and forms for the year you are filing.
This is the usual filing pattern, not a determination that you must file. Filing thresholds, age or dependent status, other income and withholding refunds can change which returns you need.
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 | Kansas home state |
|---|---|---|
| Tax before the modeled other-state credit | $3,692 | $4,780 |
| Modeled other-state credit subtracted | $0 | $3,692 |
| Tax after that credit | $3,692 | $1,089 |
Total: $3,692 + $1,089 = $4,780 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 Kansas, 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.
State tax at different salaries
| Wages | To CO | To KS | Modeled total | If you worked in KS |

| $75,000 | $2,592 | $794 | $3,385 | $3,385 |
| $100,000 | $3,692 | $1,089 | $4,780 | $4,780 |
| $150,000 | $5,892 | $1,679 | $7,570 | $7,570 |

What to do
- Ask your employer to withhold Colorado tax. If Kansas's tax is higher, withhold the difference for Kansas 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 Kansas 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 Kansas?
Yes. Colorado taxes wages earned there by nonresidents. On $100,000 that's about $3,692.
Do I have to file taxes in both Kansas and Colorado?
Usually yes: a nonresident return in Colorado and a resident return in Kansas, 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. Kansas credits the tax you pay Colorado, so your total is about $4,780 on $100,000, compared with $4,780 if you also worked in Kansas. Local city or county taxes may still apply.
