Frequently Asked Questions
Who needs to pay quarterly estimated taxes?
You generally need to pay quarterly estimated taxes if you expect to owe $1,000 or more in federal tax after subtracting withholding and credits. This commonly applies to self-employed individuals, freelancers, landlords, and investors with significant income not subject to employer withholding.
What are the quarterly estimated tax due dates?
For the 2025 tax year, the four quarterly due dates are April 15, June 16, September 15, and January 15 of the following year. If a due date falls on a weekend or federal holiday, the deadline moves to the next business day. Payments are made using IRS Form 1040-ES.
What happens if I miss a quarterly payment?
If you miss a quarterly payment or underpay, the IRS may charge an estimated tax penalty calculated as interest on the underpaid amount for the period it was late. The penalty rate is based on the federal short-term interest rate plus 3 percentage points. You can avoid penalties by meeting the safe harbor rules.
What is the safe harbor rule for estimated taxes?
The safe harbor rule lets you avoid underpayment penalties by paying at least 100% of your prior year's total tax liability (110% if your AGI exceeded $150,000) or 90% of your current year's tax liability, whichever is smaller. Meeting either threshold through estimated payments and withholding protects you from penalties even if you owe at filing time.
