After you file

File a non-resident Idaho income tax return to claim state withholding that your previous employer took out by mistake.

You can ask your former employer to send you a corrected W-2 and return the Idaho tax withheld, but most employers will not do that, so you’ll have to file a tax return.

Idaho does not tax remote employees.

See Should I Withhold Income Tax?

On your Idaho return, change your income to $0. The refund should be the same as your withholding.

Consider filing by mail. Attach a note (and letter from your former employer, if you can get one) explaining that tax was withheld by mistake because you were remote and never lived or worked in Idaho.

If you mail your return, we suggest sending it by certified mail with delivery confirmation.
