Hi, I'm Mark from Free Tax Com. If you earn income in a state that you don't live in, or if you receive any type of income in another state, when tax time rolls around, you'll likely have to file a non-resident tax return. To start out, you have to determine the exact amount of money you earned in the other state, as well as how much of your income was earned within your home state. To make this process simpler, complete your federal return first, as you may need some information from the federal return. Most non-resident returns have two columns in which you will list your income. In the first column, you'll list your total income as per your federal return, while non-resident income is listed in the second column. Next, you use those totals to calculate the non-resident percentage, which will help determine your deductions, tax liability, and taxable income allocation. In some states, you determine your non-resident taxable income by first figuring out your taxable income as if you were a state resident. Next, you multiply that total by your determined non-resident percentage to get your non-resident taxable income. In other states, you multiply your non-resident percentage by the total of federal deductions. The resulting amount is your non-resident deduction amount, which you subtract from your non-resident income. There are some federal deductions which aren't eligible for deduction at the state level, which will require you to account for them on your state return. However, you can add state deductions not available on federal returns. During the tax year, you may relocate to another state. If this occurs, you may need to file a part-year resident return instead. You will have to file a state return in your residence state, and you'll have to include all income you made, regardless of where it...
