Quarterly estimated tax payments are generally due on the following dates:

  • 1st Quarter: April 15
  • 2nd Quarter: June 15
  • 3rd Quarter: September 15
  • 4th Quarter: January 15 of the following year

If the due date falls on a weekend or holiday, the payment is due the next business day.

If you forget to make a payment, it’s important to act quickly. Submit the missed payment as soon as possible to reduce penalties and interest. If the next payment date is near, you can make two payments at once to catch up. Paying late is better than not paying at all, as it minimizes penalties and helps you stay on track for future payments.
