If you work remotely, you generally pay state income tax to the state where you are physically sitting when you do the work, and also to your home state if it’s different. Your employer’s address doesn’t control this. That means a remote worker can owe returns in more than one state, and in a few specific situations can even owe tax to a state they’ve never set foot in.
The Default Rule: Tax Follows Where You Sit
State income tax follows your physical location during working hours. Tax professionals call this “source income,” and it means the state where your laptop is open has first claim on taxing what you earn there. Where your employer is headquartered and where your paycheck is issued do not override this. Spend three months working from a cabin in another state, and that state can tax the income you earned during those three months.
For someone who commutes to one office in one state, this is simple. For remote workers who move around, split time between two homes, or take working trips, each state where you actually perform work can potentially require a tax return and take a slice of your wages.
Your Home State Taxes You Too
Most states with an income tax tax their residents on all income, no matter where it was earned. So your home state taxes your worldwide income, and any other state you worked in can tax the portion earned inside its borders. Figuring out which state is your “home state” is therefore one of the highest-stakes questions you’ll face.
Two concepts control it. Your domicile is your permanent home, the fixed place you intend to return to. You can only have one domicile at a time, and states look at concrete signals of intent: where you vote, where your license is issued, where your family lives, where you keep your things.
Residency is looser. Many states treat you as a statutory resident if you spent more than 183 days there in the year, even if you consider somewhere else your permanent home. That’s how you can end up a resident of two states at once, and it’s exactly where double-taxation problems start.
The Convenience of the Employer Rule
This is the trap that catches the most remote workers. In most states, if you work from home, your income is sourced to your home state and that ends it. But a small group of states say: if your employer has an office in our state and you could have worked from that office, we still get to tax the income, even on days you never set foot here.
Five states enforce a full version of this rule: Connecticut, Delaware, Nebraska, New York, and Pennsylvania.1Tax Foundation. How Are Remote and Hybrid Workers Taxed? New York’s version is the most aggressive and the most litigated. If a nonresident employee’s primary work location is a New York office, days worked from home in another state are treated as New York workdays unless the remote arrangement is a necessity of the employer rather than the employee’s personal preference.2Tax.NY.gov. TSB-M-06(5)I: New York Tax Treatment of Nonresidents and Part-Year Residents Application of the Convenience of the Employer Rule The “necessity” bar is high. A general company remote-work policy usually doesn’t qualify. The employer typically needs a real business reason, such as a satellite office assignment or a role that requires on-site presence somewhere else.
Connecticut and New Jersey apply a reciprocal version, meaning it only kicks in if you live in a state that also enforces its own convenience rule. Alabama applies a version of the rule as well. The practical result: a remote worker living in New Jersey and working for a New York employer can face taxation from both states on the same income.
If you work remotely for an employer in one of these states, ask for written confirmation that your remote arrangement is a business necessity. Facts that support that argument include the employer having no office space available for you, requiring you to be in a specific region for client coverage, or hiring you specifically as a remote worker with no expectation of on-site work.
Traveling to Other States for Work
Remote workers who travel to other states for meetings, conferences, or short projects often assume they only need to worry about states where they spent real time. That’s usually wrong. As of 2026, 22 states have no meaningful filing threshold for nonresidents, meaning even a single day of work performed there can trigger a filing requirement and tax on that day’s income.3Tax Foundation. Nonresident Income Tax Filing and Withholding Laws by State, 2026
A few states are more forgiving. Illinois, Indiana, Louisiana, and Montana each use a 30-day threshold for nonresidents.3Tax Foundation. Nonresident Income Tax Filing and Withholding Laws by State, 2026 North Dakota uses 20 days, but only if you live in a state with no income tax or a comparable exclusion. These are the exceptions. Congress has repeatedly considered the Mobile Workforce State Income Tax Simplification Act, which would create a uniform 30-day threshold nationwide, but as of 2026 it has not been enacted.4Congress.gov. S.1443 – Mobile Workforce State Income Tax Simplification Act of 2025 For now, assume every workday in an unfamiliar state counts.
How Double Taxation Is Supposed to Be Prevented
When two states tax the same income, two mechanisms exist to keep you from paying twice.
Reciprocal Agreements
Some neighboring states have agreements letting residents pay tax only to their home state, even when they cross the border to work. If your home state has a reciprocal agreement with your work state, you file a withholding exemption form with your employer and only your home state withholds. About 30 of these agreements exist, almost all between adjacent states. They handle traditional commuters cleanly, but they don’t help if your employer is several states away or if the convenience rule applies.
Resident State Tax Credits
More commonly, no agreement applies, and the fallback is the resident state tax credit. You file a nonresident return in the state where you earned the income, pay tax there, and then claim a credit for that tax on your home state return. This usually eliminates double taxation, but not always. The credit is capped at what your home state would have charged on the same income. If the other state’s rate is higher, you pay the difference.
Where the Credits Fail
The convenience of the employer rule breaks this system. Say you live and work from home in California for a New York employer. California taxes you as a resident on all your income. New York taxes you under its convenience rule because you could have worked at the company’s New York office. California gives residents a credit for taxes paid to states where they physically performed work, but you didn’t physically work in New York. California isn’t obligated to credit tax imposed by New York’s convenience rule, so both states tax the same income with no offsetting credit.1Tax Foundation. How Are Remote and Hybrid Workers Taxed? This affects thousands of workers employed by companies in New York and the other convenience-rule states.
Living in a State With No Income Tax
Nine states impose no individual income tax on wages: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you live and work remotely in one of these, you have no state income tax filing obligation on your wages, even if your employer sits in a high-tax state.
Two caveats. If your employer is in a convenience-rule state, that state can still claim your wages are taxable there. And if you travel to other states for work, those states can tax the days you earned income while physically present.
Local and City Income Taxes
State taxes aren’t the only layer. Some cities and counties levy their own income taxes, and the rules for remote workers vary widely. Several hundred Ohio municipalities impose local income taxes, as do cities including Philadelphia, Detroit, and New York City. Philadelphia exempts nonresident remote workers from its wage tax on days they work from home outside the city, taxing them only for days they physically report to a Philadelphia office. Ohio cities have had shifting rules around remote work. If your employer is in a city with a local income tax, check whether that city taxes nonresidents who never physically work there. The answer often turns on local ordinances rather than state law.
Fixing Your Withholding
The most common payroll problem for remote workers is withholding aimed at the wrong state. If your employer’s payroll system defaults to their headquarters state and you work somewhere else, you can end up over-withheld in one and under-withheld in the other. That doesn’t change your actual tax bill, but it creates a cash-flow problem and forces extra returns to claim refunds.
Tell your employer’s payroll department where you actually work. Most states have their own version of a withholding allowance certificate, similar to the federal W-4, that directs your employer to withhold for your state. If your employer won’t or can’t adjust withholding, make quarterly estimated payments directly to the state where you owe tax. Estimated payments are typically due in April, June, September, and January, tracking the federal schedule.
Some employers, especially smaller ones, aren’t registered to withhold payroll taxes in every state where their remote workers live. Registering in a new state creates ongoing obligations, so this can be a real logistical barrier rather than negligence.5National Conference of State Legislatures. State and Local Tax Considerations of Remote Work Arrangements If your employer can’t register, the responsibility shifts to you through estimated payments.
If You Missed a Filing
Filing a nonresident return in every state you worked in is easy to overlook, especially for short trips. States do enforce these requirements, and the penalties follow a familiar pattern: a percentage-based penalty for filing late (often 5% of unpaid tax per month, capped at 25%), a separate late-payment penalty, and compounding interest. States that learn about unfiled returns through information sharing with the IRS or other states can assess penalties retroactively.
You can reduce exposure by meeting safe harbor thresholds. Federally, you avoid underpayment penalties if your withholding and estimated payments cover at least 90% of the current year’s tax or 100% of last year’s (110% if your adjusted gross income exceeded $150,000). Most states follow similar rules, though the exact percentages and thresholds vary. Professional preparation for a multi-state return usually runs $200 to $400, which is often worth it given how quickly penalties compound.
If you realize you should have filed a nonresident return in a prior year, file it late rather than not at all. Most states reduce or waive late-filing penalties when you come forward voluntarily before they contact you, and interest on the underlying tax is easier to swallow than interest plus the full penalty stack.
