Individuals who must make estimated payments

If you didn't pay your last installment of estimated tax by January 15, you may choose (but aren't required) to file your income tax return (Form 1040 or Form 1040-SR) for 2020 by February 1. Filing your return and paying any tax due by February 1 prevents any penalty for late payment of the last installment. If you can't file and pay your tax by February 1, file and pay your tax by April 15.
