Technically you don't file taxes.u00a0 Instead taxes are automatically witheld from your paycheck and once a year, you file an income tax return statement.u00a0 If it turns out that more money was witheld than you actually owe (the most common case), the government will send you a check for the difference.u00a0 If instead you owe more than the amount that was witheld, you will have to send a check for the difference along with your income tax return.u00a0 The address you need to send your completed and signed form is included with the instructions (it may also be on the form itself).Ernest Montague is incorrect about the 1040 NR form (the form he is referring to is the 1040 EZ).u00a0 Since you are not a citizen, you will need to file either the 1040 NR or the 1040 NR EZu00a0 (NR stands for Non-Resident).u00a0 The 1040 NR EZ is the simpler form.u00a0 If the instructions say you can use the 1040 NR EZ, then you should do so.u00a0 Otherwise, you will have to use the longer 1040 NR form.You can download these forms and their instructions from the IRS at Forms & Pubs Just enter the form number (1040 NR or 1040 NR EZ) in the search field.You can download the Massachusetts state form and instructions at 2023 Massachusetts Income Tax Forms and Schedulesu00a0 Again, download the non-resident form.Good Luck!
