- 1). File tax returns by the correct deadline pertaining to each tax form. The majority of tax forms are due no later than April 15. Some, such as corporate returns, are due March 15. Read the instructions for each tax form that you have to file very carefully to ensure that you file by the correct date to avoid interest and penalties.
- 2). Attach all required documentation to each tax return. This includes Copy B of your W2s, 1099s, and all other statements showing withholding.
- 3). Mail each return to its appropriate address, listed on the instructions. Mailing a form to the incorrect address can result in delayed processing or penalties.
- 4). Submit only accurate and correct information. Incorrect information, whether intentional or unintentional, will result in penalties. Tax fraud is against the law and can result in a criminal punishment.
- 5). File an extension of time for an additional six months to file your return if you cannot file by the appropriate deadline.
