1040 Filing Basics

Taxes are the funds that the federal government uses to operate. As a citizen, resident alien, or nonresident alien, what's your role in paying federal income taxes? You need to know:

  • Whether you have to file a return
  • If so, when to file a return
  • Where to file a return
  • Which tax form to use
  • What tax filing status so use
  • How many personal exemptions you can take

The answers to these questions can depend on your income, marital status, and other factors. What's more, the answers can change from year to year; you may not have needed to file a return last year but must do so this year.
