Preparing your Resident Return
A resident return is the return you have to file in the state where you are a resident. This return will tax you on all of your income, regardless of the state where it was earned.
For most people this is very simple – the state where you are a resident is the one where you live and work. But for people whose lives involve multiple states, the first step to filing state taxes is figuring out where you are a resident.
Every state has different requirements for who qualifies as a resident for tax purposes. You need to visit the websites of the tax authorities of the states in question to figure out where you are a resident.
You should note that there are nine states without income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you are resident of one of these states, you don’t need to file a resident tax return.
Preparing your Part-Year Resident Return
A part-year resident return is for people who moved during the tax year. If you were a resident of one state for part of the year and then a resident of another state for part of the year, then you need to file a part-year resident return in the first state and a part-year resident return in the second state.
A part-year resident return taxes you on all of your income for the portion of the year that you were a resident of that state. Let’s say you started the year living in Illinois. Then in July you moved permanently to New York. You would then have to file a part-year tax return in Illinois that taxes you on all of your income you earned during the first six months of the year. Then you will have to file a part-year resident return in New York that taxes you on the income you earned during the last six months of the year.
Preparing your Non-resident Return
You need to file a nonresident return for any state (other than the state where you live) in which you earned money. This nonresident return will only tax you on the income you earned in that state.
Here’s an example. Let’s say you live in New Jersey, but you work in New York. You’ll need to file a resident return in NJ. You will also have to file a nonresident return in NY and pay taxes on the income you earned there.
Worried about being double-taxed? Don’t be. When you file your state returns, you will have the opportunity to claim a credit for the taxes that you’ve already paid to another state through withholding. The states will then settle accounts among themselves.
You may also have to file a nonresident return for any state that had taxes withheld from your paycheck. Normally you only have to file taxes in the state(s) where you were a resident and where you earned your income.
But sometimes payroll departments goof up and withhold taxes for a state you neither lived or worked in. This commonly occurs when you work for a company that is headquartered in a different state than where you work. You’ll need to file a return just so you can get that money back as a refund.
