What Is Estimated Tax?

Estimated tax is how you pay tax throughout the year on income that does not have tax withheld from it, such as self-employment or investment income.

Because the U.S. tax system is pay-as-you-go, the government expects to receive tax as you earn income, not only when you file. Employees meet this through paycheck withholding. If you earn income without withholding, you make estimated tax payments to keep up instead.

Estimated tax can cover both income tax and self-employment tax. You generally need to pay it if you expect to owe about 1,000 dollars or more for the year after subtracting any withholding and credits. Payments are usually made on a quarterly schedule across the year.

Falling behind on estimated tax can lead to an underpayment penalty, even when you pay your full balance at filing time. Setting aside a portion of untaxed income as you receive it makes these payments manageable.
