Live in North Carolina, Work in Idaho: Which State Taxes Your Paycheck?

Both states — credit offsets the double taxIdaho withholds

Answer

You file twice: Idaho first, then North Carolina. There is no reciprocity agreement between these two states, so Idaho taxes the income where it was earned and North Carolina taxes it again as resident income — with the resident credit removing the double charge rather than an exemption form preventing it.

Without an agreement between North Carolina and Idaho, the overlap is handled after the fact rather than prevented. That is why the filing order matters: the Idaho figure is an input to the North Carolina return, so completing North Carolina first means doing it twice.

A North Carolina resident taxed by another state on the same income claims the credit for taxes paid to other states on Form D-400TC. The credit is capped at the North Carolina tax on that income, so it removes the double tax but never refunds the excess when the other state charges more.

What you file

  1. 1Nonresident return · IdahoForm 43

    File the Idaho nonresident return FIRST — you need the Idaho tax figure before you can complete North Carolina.

  2. 2Resident return · North CarolinaForm D-400TC

    File a North Carolina resident return reporting all income, then claim the credit for tax paid to Idaho. The credit is capped at what North Carolina would have charged on that same income, so if Idaho taxes it at a higher rate the difference is not refunded.

Questions people actually ask

I live in North Carolina and work in Idaho. Which state takes the tax out of my paycheck?

You file twice: Idaho first, then North Carolina. There is no reciprocity agreement between these two states, so Idaho taxes the income where it was earned and North Carolina taxes it again as resident income — with the resident credit removing the double charge rather than an exemption form preventing it.

Which state should my employer be withholding for?

Idaho. The wages are sourced to Idaho, so Idaho withholding is correct and there is no North Carolina 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. North Carolina gives residents a credit for tax paid to Idaho on the same income, claimed on Form D-400TC. The credit is capped at the North Carolina tax on that income, so if Idaho taxes it more heavily the excess is not refunded by either state.

How current is this?

The North Carolina and Idaho rules on this page were last checked against North Carolina Department of Revenue and Idaho State Tax Commission on 2026-08-07. We re-check the full grid every December after state legislative sessions close, and re-check the convenience-of-the-employer states quarterly because that is where the rules move fastest.
