How Does Working in One State but Living in Another Affect My Taxes?
A new job across the state line seemed like a simple commute upgrade, until the first paycheck arrived with withholding for a state the person doesn’t even live in, followed by a nagging worry about whether two separate tax returns are now required.
In short
Working in one state while living in another can create a filing obligation in both states — one because income was earned there, the other because that’s where the person legally resides. Most states offer a credit so the same income isn’t taxed twice in full, but the mechanics depend on which two states are involved and whether they have a reciprocity agreement. It helps to check current guidance from both states’ tax agencies before assuming either outcome.
Why two states can both have a claim
States generally tax income on two different bases: residency and source. A home state can tax all of a resident’s income no matter where it was earned, while a work state can tax income earned within its borders regardless of where the earner lives. When those two claims overlap, the same paycheck can technically appear on two state returns. This is common for people who live near a state border, and it’s one reason moving to a no income tax state for the savings alone doesn’t always simplify things the way it initially looks like it would if a paycheck still originates elsewhere.
Reciprocity agreements change the picture
Some neighboring states have reciprocity agreements, meaning a resident who works in the neighboring state only pays income tax to their home state, not the work state. Where this exists, an employee typically files a specific exemption form with their employer so the work state doesn’t withhold anything in the first place. Where no such agreement exists, the more typical process involves filing a nonresident return in the work state and a resident return in the home state, then claiming a credit on the resident return for taxes paid to the nonresident state.
What the credit actually does
The credit for taxes paid to another state is designed to prevent full double taxation, but it doesn’t always erase every dollar of overlap. If the work state’s tax rate is higher than the home state’s, the credit may only offset up to what the home state would have charged on that income, leaving a small residual difference. If the work state has no income tax at all, there may be nothing to credit, and the home state simply taxes the income as usual. These outcomes shift with current state tax rules, so a general estimate today may not match the numbers by the time a return is actually filed. Getting the withholding wrong on either side is also part of why some people end up owing a penalty for not paying enough tax during the year if neither employer withheld quite the right amount.
Remote and hybrid work complicates it further
Splitting time between a home office and an employer’s location in another state raises the question of exactly which days of income “belong” to which state, and a handful of states apply a “convenience of the employer” rule that can tax income earned from a home office anyway. Documentation — where the work was physically performed, and why — tends to matter more than people expect if a state ever asks. Anyone whose work arrangement changes mid-year, such as military families who move states more often, often faces an even more layered version of this same overlap question.
What to weigh
There’s no universal shortcut here, because the outcome depends entirely on which two states are involved, whether a reciprocity agreement exists between them, and how income is sourced under each state’s specific rules. Someone in this position generally benefits from checking both states’ current tax agency guidance, keeping records of where work was actually performed for as long as tax records are typically worth retaining, and confirming employer withholding matches the intended filing approach before the difference becomes a bigger reconciliation at tax time. A tax professional familiar with multistate returns can walk through the specific combination of states involved, since general rules only go so far once a particular case has its own details.
