Live in Kansas, Work in California: Which State Taxes Your Paycheck?
Answer
California withholds and Kansas credits. Without an agreement between them, both states are entitled to tax income earned in California by a Kansas resident. The mechanism that stops you paying twice is the credit on the Kansas resident return, which is why the California return has to be completed first.

Two states can lawfully tax the same wages: California because the work happened there, Kansas because you live there. Nothing prevents the overlap in advance — it is unwound afterwards, on the Kansas return, through the credit for taxes paid to another state.
A Kansas resident taxed by another state on the same income claims the credit for taxes paid to other states on Form K-40 (credit for taxes paid to other states). The credit is capped at the Kansas tax on that income, so it removes the double tax but never refunds the excess when the other state charges more.
What you file
- 1Nonresident return · CaliforniaForm 540NR
File the California nonresident return FIRST — you need the California tax figure before you can complete Kansas.
- 2Resident return · KansasForm K-40 (credit for taxes paid to other states)
File a Kansas resident return reporting all income, then claim the credit for tax paid to California. The credit is capped at what Kansas would have charged on that same income, so if California taxes it at a higher rate the difference is not refunded.

The other direction
Reversing the commute does not always reverse the answer. Living in California and working in Kansas gives:Both states — credit offsets the double tax.
Same two states, different situation

- Remote worker: Kansas → CaliforniaHome state only
- 1099 contractor: Kansas → CaliforniaHome state, plus the client state if you work there
- Moved mid-year: Kansas → CaliforniaTwo part-year returns

Questions people actually ask
I live in Kansas and work in California. Which state takes the tax out of my paycheck?
California withholds and Kansas credits. Without an agreement between them, both states are entitled to tax income earned in California by a Kansas resident. The mechanism that stops you paying twice is the credit on the Kansas resident return, which is why the California return has to be completed first.
Which state should my employer be withholding for?
California. The wages are sourced to California, so California withholding is correct and there is no Kansas withholding to set up.
Will I end up paying tax twice on the same income?
Not twice over, but you will pay the higher of the two rates. Kansas gives residents a credit for tax paid to California on the same income, claimed on Form K-40 (credit for taxes paid to other states). The credit is capped at the Kansas tax on that income, so if California taxes it more heavily the excess is not refunded by either state.
