If you did not pay your last installment of estimated tax by January 16, file your income tax return for 2017 on this date and pay the entire balance due with your return, thereby avoiding any penalty for late payment of the last installment. Use Form 1040 or 1040A. However, see below for special rules for farmers and fishermen.

For an automatic 6-month extension, file Form 4868 and pay any tax that you estimate will be due. Then file Form 1040 or 1040A by October 15. If you get an extension, you can’t file Form 1040EZ. (You can use one Form 4868 to file for both your income tax and gift tax extensions.)
