Your income tax liability may change based on the state you're in, but you should expect to file taxes for both states: one return as a resident for the state where you live and a separate return as a nonresident for the state where you work.
What if I worked in two different states?
If both states collect income taxes and don't have a reciprocity agreement, you'll have to pay taxes on your earnings in both states: First, file a nonresident return for the state where you work. You'll need information from this return to properly file your return in your home state.
Do I have to pay taxes in two states if I work remotely?
Where do I pay state taxes if I live in a different state than my employer? As a remote worker, you must pay tax on all your income to the state you live in (if your state has personal income tax). This is true no matter where your employer is located.
Is local tax based on where you live or work?
Local income tax might be withheld on wages you earn inside city, county, and school district boundaries. If you live or work in an area that levies a tax, your wages will be taxed by that jurisdiction.
How many days can I work remotely from another state?
In California, it's 45 days. Some states have a first-day rule, which means that if you work there for even one day, you owe state income tax. So, working remotely in your new home and traveling back to your old office could open you up to tax liability in both states.
