How Do Taxes Work If You Work Remotely in a Different State Than Your Employer?
Working from a home office in one state for a company headquartered in another has become common enough that it raises a question many people don’t think about until tax season: which state actually gets to tax that income.
The short answer
In general, the state where the work is physically performed has the primary right to tax that income, even if the employer is based elsewhere, though the details vary by state and by the specific arrangement. A resident state tax credit is generally what prevents the same income from being taxed twice when an employee lives in one state but earns income connected to another.
Why work location generally drives the tax
State income tax rules are generally built around two connections to a state: residency and the source of the income. Residency is fairly straightforward, but sourcing rules for wage income often hinge on where the work is actually performed, not where the company’s office or payroll department is located. That means a person who lives in one state and works entirely from home for an out-of-state employer may only owe tax to their home state, while someone who occasionally travels to the employer’s home state for in-person work could have income sourced there for those days.
The resident credit and double taxation
When a state other than the one someone lives in has a legitimate claim to tax part of their income, the home state generally offers a credit for taxes paid to that other state, applied against the resident’s own tax bill on the same income. This resident credit is the main mechanism that keeps remote workers from paying full tax twice on the same dollars. It doesn’t always offset the full amount, though, particularly if the two states’ tax rates or rules differ, so the total combined state tax bill can end up somewhat different than it would be working entirely within one state.
A few state-specific wrinkles
Some states apply what’s sometimes called a “convenience of the employer” rule, under which income can be sourced to the employer’s state even for days worked remotely, if the remote arrangement is considered a matter of the employee’s own convenience rather than a business requirement. This is one of the more complicated areas of remote-work taxation, and it varies significantly by state, which is part of why moving between states mid-year or taking a remote job based in a different state than where someone lives is worth researching against the specific states involved rather than assuming a single national rule applies.
What to check before assuming one state applies
- Confirm the sourcing rule. Each state sets its own approach to sourcing remote income, so the employer’s state and the employee’s state both matter.
- Track work location. Days spent physically working in a different state, even briefly, can sometimes create a filing obligation there.
- Review payroll withholding. Employers don’t always withhold correctly for remote arrangements, and adjusting withholding can help close any gap discovered mid-year.
- Check the resident credit. Confirming that the home state credit applies to the specific out-of-state tax paid helps avoid double taxation on the same income.
The bottom line
Remote work across state lines doesn’t have one universal rule — it depends on where the work happens, how each state defines sourcing, and whether a resident credit is available. Because these rules differ by state and change over time, they’re worth checking against the specific states involved rather than assumed from general knowledge.
