Do I Need to File a Nonresident State Tax Return?
Do you work in a state where you don't live?
It's not as uncommon as you might think—an individual lives in one state but is employed in another, or he otherwise does some work or earns money in a location where he doesn't reside. In fact, this happens quite often among taxpayers who live nearby to state lines. The situation can complicate things a bit at tax time, but not to a great extent if you understand the rules.
If you've earned money in another state, it's likely that you'll have to file a nonresident state tax return there because this tax return is due to any state where you've worked but don’t have residency. You must file such a return in addition to a tax return with your home state, but this doesn't mean that you'll end up paying taxes on that income twice.
Let’s go over the basics to help you decide if you must file a nonresident return and, if so, how it will affect you.
When You Must File a Nonresident Return
Plain and simple, you must file a nonresident return if you worked or earned income in a state where you're not a resident. For example, Jane lives in New Jersey and commutes to work in New York. Jane would file a nonresident return in New York and a resident tax return in New Jersey.
You must also file a nonresident return if your employer withheld state taxes for the wrong state and you want a refund from that state, or if you made any non-employment income in a state other than your home state.
You May Not Need to File a Return in Reciprocal States
Certain states have agreements that allow residents of other states to work in there without filing a nonresident return. This is common among neighboring states where crossing over the line to go to work is common. These agreements are known as reciprocal agreements. You probably won't have to file a return in the nonresident state if your resident state and the state you're working in have such an agreement in place. These agreements typically cover only earned income, however, that which you collect from actual employment.
And if you had taxes withheld in the nonresident state, you'll still have to file a return there to get that money refunded.
Fifteen states have reciprocal agreements with one or more other nearby states as of 2017: Arizona, Illinois, Indiana, Iowa, Kentucky, Maryland, Michigan, Minnesota, Montana, North Dakota, Ohio, Pennsylvania, Virginia, West Virginia and Wisconsin. The District of Columbia also has reciprocal agreements with the states of Maryland and Virginia. New Jersey had an agreement with Pennsylvania for more than 40 years, but reciprocity ended on December 31, 2016.
Of course, just like in New Jersey, this can change at any time, so check with the state tax authority in your nonresident state so you can be sure of your tax filing obligations. Your employer's human resources department should be able to tell you as well if it has one. You can also check with your own tax authority if you live in one of the above states to determine which other states have reciprocity with your home turf.
Non-Employment Income That Is Taxable to Nonresidents
Most states tax any income that is sourced to their state, including the income of nonresidents, so you don’t have to actually work in a state to owe taxes there. These other types of income can also be taxable to a nonresident:
- Your income as a partner in an LLC, partnership, or S-corporation. Your share as a partner can be taxable in the state where the company is based. Note that this does not apply if you are simply an employee of the company.
- Income from services performed within the state. For example, an appliance repair person who travels across state lines to repair an oven in someone’s home there must file a non-resident return.
- Lottery or gambling winnings are taxable in the state where you won, so you'd have to file a return there.
- Income from the sale of property within a state requires a nonresident tax return, as does rental income.
- Carrying on a business, trade, profession, or occupation in a state. For example, if you worked as a consultant or contractor in another state, you'd have to file a non-resident return there.
Will You Pay Taxes Twice?
Fear not. The U.S. Supreme Court has your back. The Court rules in May 2015 that two states cannot legally tax the same income. The decision didn't come lightly because it will cost some states a great deal of revenue. Justices debated and listened to oral arguments for over six months before they ultimately voted 5-4 that states must exempt from taxation earnings and other sources of income that were taxed elsewhere.
