Yes, non-residents generally do pay state taxes on income they earn inside another state’s borders. As of 2026, 22 states require a non-resident return starting with the first dollar earned there, while others set minimum thresholds ranging from $100 to over $15,000 before any filing obligation kicks in.1Tax Foundation. Nonresident Individual Income Tax Filing and Withholding Laws by State, 2026 Nine states impose no broad-based individual income tax at all, so ordinary wages earned there create no state filing duty. Whether you actually owe depends on the type of income, where you earned it, and whether an exemption, reciprocity agreement, or federal protection applies.
What Income a State Can Tax You On
The clearest trigger is wages you earn while physically working in another state. Two weeks on a job site in a state where you don’t live ties those earnings to that state. Business owners face the same principle: profits from a store, warehouse, or office operating in another state get allocated to that state’s tax rolls even when the owner runs everything from home. States use formulas weighing sales, employees, and property inside their borders to decide how much business income they can claim.
Income from real property follows the property, not the owner. Rental income from an apartment building and gains from selling land are taxable where the property sits. Gambling and lottery winnings work the same way. A jackpot at an out-of-state casino or a winning ticket bought across the border is locally sourced income, and the state will often withhold before you leave. Multistate lottery prizes are sourced to the state where the ticket was purchased, not where you live when you collect.
One category surprises people: stock options and deferred compensation tied to work you previously performed in a state. If a bonus was earned over two years while you split time between two states, each state can claim a share based on the days you worked there during the earning period. That is why keeping careful records of where you physically worked matters more than most people realize.
When You Actually Have to File
Not every dollar earned in another state triggers a filing requirement. States take three broad approaches to the threshold, and the differences are dramatic.
- Dollar-based thresholds. Nine states require a non-resident return only above a set amount, ranging from $100 to $15,300 for a single filer. The lowest barely provide any relief; the highest effectively exempt short projects.
- Day-based thresholds. About ten states use the number of days you physically worked there, with safe harbors ranging from 12 to 30 days. Stay under the limit and you don’t need to file. Some states combine day and dollar tests, so you must exceed both before an obligation arises.
- No threshold at all. Twenty-two states require a non-resident return if you earned any income in the state, even from a single day of work.1Tax Foundation. Nonresident Individual Income Tax Filing and Withholding Laws by State, 2026
Some day-based safe harbors carry a mutuality requirement: they apply only to non-residents whose home state offers a similar exemption in return. Alabama, North Dakota, Utah, and West Virginia all attach that condition.1Tax Foundation. Nonresident Individual Income Tax Filing and Withholding Laws by State, 2026 Professional athletes and entertainers are almost universally carved out of these safe harbors. Above a certain income level or in a designated high-profile category, most states require withholding and filing regardless of how few days you spent there.
States With No Income Tax
Nine states impose no broad-based personal income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming.2Tax Foundation. State Individual Income Tax Rates and Brackets, 2026 If your only out-of-state income comes from work performed in one of these, you have no non-resident return to file there. Washington is a partial exception. It doesn’t tax wages or business income but does tax capital gains for high earners, so large investment gains with a Washington connection could still create an issue.
Reciprocity Agreements for Commuters
About 16 states and the District of Columbia have reciprocal tax agreements with at least one neighboring state. These override normal source-based taxation for wages, so you only pay income tax to your home state even though you commute across the border to work. The District of Columbia exempts all non-resident workers regardless of where they live.
These agreements exist mostly in the mid-Atlantic and Midwest, where commuters routinely cross state lines. Illinois and Indiana, Kentucky and Ohio, Maryland and Virginia, Pennsylvania and New Jersey each have a standing arrangement. Coverage is not universal. Plenty of state borders have no reciprocity at all, and each agreement is negotiated between specific states.
To benefit, you file a certificate of non-residence (sometimes called an exemption certificate) with your employer. That tells payroll to withhold for your home state instead of the work state. Forget the form and your employer withholds for the work state by default, forcing you to file a non-resident return there just to get a refund. Reciprocity applies only to wages and salary. Rental income, business profits, and investment gains from across the border remain taxable under normal rules.
Remote Work and the Convenience of the Employer Rule
Traditional rules tie income to the state where you’re physically sitting when you do the work. Remote work has scrambled that logic. The sharpest departure is the “convenience of the employer” rule. If your employer is based in the state and you work remotely from somewhere else for your own convenience rather than the employer’s necessity, that state taxes your full salary as if you were working at the office.
New York enforces this most aggressively. Connecticut, Delaware, Nebraska, New Jersey, Oregon, and Pennsylvania apply variations. The practical effect is real: a software engineer living in New Hampshire and working remotely for a New York employer may owe New York income tax on their entire salary. The only defense is proving the remote arrangement is a necessity of the employer, not a preference. That usually requires showing the employer has no office space for you or specifically needs you in a different location for business reasons.
Freelancers and independent contractors are analyzed differently. You’re generally taxed based on where you physically perform the services, not where your client is located. Consulting done from your home office for a client in another state stays with your home state. Travel to the client’s state to perform work on site, and that state can tax the income tied to those days.
Federal Protections: Retirement Income and Military Pay
Federal law removes two major categories of income from state reach when you don’t live there.
Retirement Income
Under federal law, no state may tax the retirement income of someone who doesn’t live there.3Office of the Law Revision Counsel. U.S. Code Title 4 – 114 Limitation on State Income Taxation of Certain Pension Income The protection covers distributions from 401(k) plans, traditional and Roth IRAs, 403(b) annuities, government pension plans, SEP-IRAs, and deferred compensation under section 457 plans. Military retired pay is specifically included. If you spent your career in one state, moved to another in retirement, and now receive pension checks from your former employer, the old state cannot tax those payments.
There is a technical limit for certain nonqualified plans. Payments from an employer’s nonqualified deferred compensation arrangement only qualify if they come as substantially equal periodic payments over your lifetime or over at least 10 years.3Office of the Law Revision Counsel. U.S. Code Title 4 – 114 Limitation on State Income Taxation of Certain Pension Income A lump sum from that type of plan could fall outside the federal shield. For most retirees drawing from standard accounts, the protection is absolute.
Military Pay
Service members don’t gain or lose a state of residence for tax purposes just because the military stations them somewhere. Military compensation is taxable only in the state of legal domicile.4Office of the Law Revision Counsel. U.S. Code Title 50 – 4001 Residence for Tax Purposes A soldier domiciled in Texas but stationed in Virginia owes no Virginia income tax on military pay.
Military spouses get a parallel protection. A spouse who moves to a new state solely to accompany the service member can elect to keep the service member’s tax residence, the spouse’s own prior domicile, or the permanent duty station. Income the spouse earns in the stationed state is not taxable there so long as the spouse is present only because of the military orders.4Office of the Law Revision Counsel. U.S. Code Title 50 – 4001 Residence for Tax Purposes The protection covers wages from a civilian job the spouse takes in the new state, not only military pay.
How Credits Prevent Double Taxation
When you earn income in a state where you don’t live, two states have a claim on the same dollars: the source state where you earned it, and your home state, which taxes your worldwide income. The mechanism that prevents paying both in full is a credit for taxes paid to another state. Your home state calculates the tax on all your income, then reduces it dollar-for-dollar by the amount you already paid to the source state on that same income.
The credit has a ceiling. Your home state will never grant a credit larger than the tax it would have charged on that income under its own rates. If you worked in a high-tax state and paid more there than your home state would have charged, you don’t get a refund of the difference; you simply owe nothing additional at home on that portion. If your home state has the higher rate, you pay the source state first and then pay your home state the difference.
To claim the credit, file your non-resident return in the work state first to fix the exact liability, then report that amount on a specific schedule of your home state’s resident return. Getting the sequence wrong or failing to carry the non-resident numbers over can delay processing or cause the credit to be denied. A handful of states flip the arrangement: instead of the home state granting the credit, the source state gives the credit to residents of states that would otherwise double-tax the income. Which state absorbs the revenue loss can change depending on the direction the agreement runs.
Part-Year Residents Are Not the Same as Non-Residents
If you moved from one state to another during the year, you’re probably not a non-resident of either state for the full year. You’re a part-year resident of both, and the treatment differs. As a part-year resident you owe tax on all income from any source received while living in that state, plus income from sources within that state after you left. A pure non-resident only owes on sourced income.
The distinction is not optional. If you kept a home in the state or spent more than roughly half the year there, many states will treat you as a full-year resident regardless of when you say you moved. Documentation of your move date, new lease or mortgage, driver’s license change, and voter registration update is the best defense of your claimed status.
Filing a Non-Resident Return
Each state that taxes non-resident income has its own return for the purpose. The structure is similar everywhere: report your total federal adjusted gross income, allocate the portion earned in that state, apply the state’s brackets to your total income to get a hypothetical liability, then multiply by the ratio of in-state income to total income. The result is what you actually owe.
Getting the allocation right is where most errors happen. You need W-2 forms that break down earnings by state, and for workers who split time across locations, a reliable record of which days you worked where. Calendar entries, travel receipts, hotel bills, and expense reports all serve as evidence if the state questions your allocation. A contemporaneous log is far more persuasive than a reconstruction from memory at tax time.
Bonuses and stock option exercises don’t allocate as simply as counting days in one pay period. A bonus earned over a full year splits by the proportion of workdays in each state across the entire earning period. Stock options may need allocation across states for the full period from grant to exercise. These items generate the most audit disputes, because taxpayers often assign them entirely to their home state without realizing the source state has a legitimate claim to a share.
Penalties for Not Filing
Ignoring a non-resident filing obligation doesn’t make it go away. States share data with the IRS under agreements authorized by the Internal Revenue Code, and they receive W-2 and 1099 data directly from employers.5Internal Revenue Service. IRS Information Sharing Programs If an employer reported paying you wages sourced to a state and no return shows up, the state’s matching systems will eventually flag it.
Penalty structures vary, but the common pattern is a monthly percentage charge on unpaid tax for failing to file, a separate monthly charge for failing to pay, and interest compounding on top of both. Maximum penalties typically cap at 25% to 50% of the tax owed, and states that find intentional evasion rather than honest oversight can impose fraud penalties reaching much higher. Even a bill of a few hundred dollars can multiply substantially over the two or three years it may take the state to catch up.
The safest move when you’re unsure whether you crossed a state’s threshold is to file anyway. A return showing zero tax due costs only your time. A missing return that should have been filed costs real money once penalties start accruing.
