Quarterly estimated taxes: how to calculate them and avoid penalties

Who needs to pay quarterly estimated taxes, the 2026–2027 due dates, the safe harbor rules and the easiest ways to pay the IRS.

By Neysi Parada Gamboa · Updated October 2026

When you work for yourself, nobody withholds taxes from your income. The IRS expects you to pay during the year, in four payments called estimated taxes. If you wait until April, you may owe a penalty on top of the tax.

Who needs to pay

Generally, you should make estimated payments if you expect to owe $1,000 or more when you file, after withholding and credits. That includes most self-employed people, gig workers, LLC owners and people with rental income.

How much to pay: the safe harbor rules

You generally avoid the underpayment penalty if your payments during the year add up to at least:

  • 90% of the tax you owe for the current year, or
  • 100% of the tax on last year's return (110% if your adjusted gross income was over $150,000)

Paying based on last year is the easiest method when your income is stable.

Do not forget self-employment tax

Your estimate must include income tax and self-employment tax (about 15.3% on most of your net profit). A common rule of thumb is to set aside 25% to 30% of your profit, but your number depends on your income and family.
