Frequently asked questions
Do I pay Idaho income tax if I live in Washington?
Yes. Idaho taxes wages earned there by nonresidents. On $100,000 that's about $4,192.
Do I have to file taxes in both Washington and Idaho?
Usually you file only one state return (a nonresident return in Idaho), though some states still require a nonresident return to get a refund of any wrongly withheld tax.
Will I be taxed twice?
No. Washington has no income tax, so you pay only Idaho's nonresident tax: about $4,192 on $100,000.
