If you’re living in one state and working in another, you’ll generally file two state tax returns each year, follow the employment laws of the state where you physically work, and keep your civic ties (voter registration, driver’s license, jury duty) with the state you call home. A credit mechanism prevents you from paying full income tax to both states on the same dollar, but local taxes, remote work rules, and licensing requirements can still catch you off guard.
Filing Two State Tax Returns
Both states have a legitimate claim to tax you. Your home state taxes residents on all income no matter where it’s earned. Your work state taxes nonresidents on income earned inside its borders. So most cross-border commuters file a resident return at home and a nonresident return in the work state.1Tax Foundation. Nonresident Income Tax Filing and Withholding Laws by State, 2026
You don’t pay full tax to both states on the same income. Your home state gives you a credit for taxes paid to your work state, which reduces what you owe at home. The U.S. Supreme Court ruled in 2015 that state tax schemes imposing double taxation on income earned in other states violate the Commerce Clause, so this credit isn’t optional.2Justia Law. Comptroller of Treasury of Md. v. Wynne, 575 U.S. 542 (2015)
The practical effect: you end up paying the higher of the two rates. Say your home state charges 3% and your work state charges 5%. You pay 5% to the work state. Your home state calculates the 3% it would have imposed, sees you already paid more elsewhere, and zeroes out your home-state bill through the credit. Flip the numbers, and you’d pay 3% to the work state and owe the 2% difference at home.
One filing tip. Always complete the nonresident return first. You need the exact figure paid to the work state to calculate the credit on your resident return.1Tax Foundation. Nonresident Income Tax Filing and Withholding Laws by State, 2026
When You Only File One Return
If either state doesn’t tax wage income, the dual filing goes away. Nine states fit that description: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming.3Tax Foundation. State Individual Income Tax Rates and Brackets, 2026
Live in one of these states and commute to a state with income tax, and you file only the nonresident return in the work state. Live in a taxing state and commute to a no-tax state, and you file only your home-state resident return. Either way, one return instead of two.
Reciprocity Agreements Between States
Even when both states tax income, a shortcut may exist. Roughly 30 reciprocity agreements are in force between pairs of states, concentrated in the Mid-Atlantic and Midwest where cross-border commuting is common. Under one of these agreements, you pay income tax only to your state of residence, and the work state agrees not to tax your wages at all.
To use a reciprocity agreement, file a withholding exemption certificate with your employer. That form tells payroll to withhold for your home state instead of the work state. Skip the form and your employer will default to work-state withholding, leaving you to request a refund from the work state at filing time.
Reciprocity applies only to earned income like wages and salaries. Investment income, rental income, and other unearned income stay with your state of residence regardless.4Tax Foundation. Do Unto Others: The Case for State Income Tax Reciprocity Not every neighboring pair has an agreement, so confirm one exists between your specific states before relying on it.
Local and Municipal Income Taxes
State returns get most of the attention, but local income taxes can add a real cost. As of 2026, 14 states have local income taxes that sometimes apply to nonresidents working inside city or county limits.1Tax Foundation. Nonresident Income Tax Filing and Withholding Laws by State, 2026 The group includes Ohio, Pennsylvania, Maryland, Indiana, Michigan, and New York.
These local taxes are separate from state income tax and may need their own return. Commute into Philadelphia, New York City, or certain Ohio municipalities, and you can face a local earnings tax on top of both state returns. Rates vary by jurisdiction. Worse, your home state’s resident credit typically covers state-level taxes only, not municipal ones, so the local piece often isn’t offset by any credit at all.
The Remote Work Tax Trap
Remote work has created a wrinkle traditional commuters don’t hit. Most states tax you based on where you physically sit while doing the work. Work from home in State A for a company in State B and you generally owe taxes only to State A. A handful of states flip that logic through what’s called the “convenience of the employer” rule.
Under that rule, if you work remotely for an employer based in one of these states, the state can still tax your income as if you were physically working there, unless your remote arrangement exists because the employer required it rather than because you chose it. States applying some version of this rule include New York, Pennsylvania, Delaware, Connecticut, Nebraska, Arkansas, and Massachusetts.5National Taxpayers Union Foundation. State Changes to Tax Compliance Burdens For Remote and Mobile Workers
New York’s version is the most aggressive. If your employer’s primary office is in New York, the state treats every day you work remotely as a New York work day unless your home office qualifies as a “bona fide employer office,” a test that’s notoriously hard to meet. The problem compounds when your home state won’t provide a full credit for taxes paid under another state’s convenience rule. Some states will credit it; others won’t, which leaves you genuinely double-taxed on the same income. Before accepting a remote role with an employer in one of these states, look carefully at how your home state treats the credit.
Which State’s Employment Laws Protect You
The state where you physically work controls your rights as an employee. Commute from State A to an office in State B and State B’s minimum wage, overtime rules, meal break requirements, and workplace safety standards all apply. Where your employer is incorporated or headquartered doesn’t change that.
The distinction matters when the two states have very different protections. Your work state might require paid sick leave, mandate meal and rest breaks, or set a higher minimum wage. As a worker physically present there, you’re entitled to those protections. State paid family and medical leave programs generally extend eligibility to anyone whose work is based in the state, regardless of where they live.
Employment contracts sometimes include a “governing law” clause naming a particular state’s laws. Those clauses can control how contract disputes are interpreted, but courts routinely refuse to enforce them when they’d strip protections the work state guarantees. A contract can’t use a choice-of-law provision to dodge a state’s minimum wage or override restrictions on non-compete agreements.
Workers’ Compensation and Unemployment
If you’re injured on the job, the work state’s workers’ compensation system is the primary place to file, because your employer pays into that state’s insurance fund based on where you work.6U.S. Department of Labor. Workers’ Compensation Workers’ comp is more flexible than most cross-border issues, though. Many states let you file in your state of residence, the state where the injury occurred, or the state where your employment contract was made. You can’t collect from multiple states for the same injury, but having a choice matters because benefit levels and medical treatment rules differ significantly.
Reporting deadlines vary. Some states give you about 30 days to notify your employer of a workplace injury. Others allow as few as 10 days, and a handful just require notice “as soon as possible.” Because you might not know which state’s rules apply until later, report any workplace injury to your employer immediately and in writing.
If you lose your job, you file for unemployment with the state where you worked.7U.S. Department of Labor. How Do I File for Unemployment Insurance You can file from your home state; no need to travel back. The work state’s benefit calculation, weekly maximum, and duration limits govern your claim.
If you worked in more than one state during the base period, you can file a combined wage claim. That pools wages across states into a single claim so you can qualify for benefits, or receive a higher weekly amount than any one state’s wages would produce alone. Federal regulations govern the process: you pick one “paying state” to handle the claim, and the other states transfer your wage records to it.8eCFR. 20 CFR Part 616 – Interstate Arrangement for Combining Employment and Wages You cannot collect unemployment from two states at once.
Professional Licensing Across State Lines
Many professions require a state-issued license, and that license is only valid in the state that issued it. Nurses, therapists, teachers, and other licensed professionals who live in one state and work in another generally need a license in the state where they practice.
Interstate licensing compacts have simplified this for some professions. Compacts let a professional hold one license that’s recognized across all member states. Major compacts exist for nurses, physicians, physical therapists, psychologists, occupational therapists, and EMS personnel.9Telehealth.HHS.gov. Licensure Compacts Not every state has joined every compact. If no compact covers your situation, you’ll need a separate license in your work state, which means additional fees and processing time.
Where You’re Legally a Resident
Working in another state doesn’t change where you’re a legal resident. Your domicile, meaning the state you consider your permanent home and intend to return to, controls your civic obligations. Voting, jury duty, driver’s license, and vehicle registration all follow your state of residence, not your state of employment.
You can only have one domicile at a time. If a question ever arises over which state is your true home, states look at a cluster of practical factors to gauge intent:
- Voter registration: where you’re registered to vote
- Driver’s license: which state issued it
- Vehicle registration: where your car is registered
- Tax filings: the address on your federal and state returns
- Property and family: where you own or rent your primary home and where your immediate family lives
Keeping these indicators consistent matters. If you split time between two states near a border, mismatched records (a license in one state, voter registration in another) can create disputes about which state gets to tax you as a resident. Pick one domicile and make sure every official record points to it.
