The four 2026 Form 1040-ES dates
The official 2026 Form 1040-ES lists April 15, June 15, and September 15, 2026, plus January 15, 2027. These periods are uneven: the second installment arrives only two months after the first. You may pay the full estimated amount by April 15 or use the installment schedule, subject to the form’s rules.
| Installment | Federal due date | Practical review before paying |
|---|---|---|
| First | April 15, 2026 | 2026 income forecast, prior-year safe harbor, Q1 bookkeeping. |
| Second | June 15, 2026 | Income earned through May and any major change in work. |
| Third | September 15, 2026 | Summer income, deductions, withholding, and year-end forecast. |
| Fourth | January 15, 2027 | Near-final 2026 records and payments already credited. |
Estimated payments generally matter when both parts of the Form 1040-ES general rule are met: you expect to owe at least $1,000 after withholding and refundable credits, and your withholding and refundable credits are expected to be less than the smaller of the applicable current-year or prior-year amount. Use the official worksheet for your facts.
Printable freelancer checklist
- Reconcile business bank and credit-card accounts before each payment review.
- Update gross receipts, Schedule C expenses, mileage, and home-office records.
- Separate the prior-year balance due from the current-year estimated payment.
- Recalculate after a major income change instead of blindly repeating the last payment.
- Pay federal and state estimates through their separate systems.
- Select the correct tax year and payment type when submitting electronically.
- Save the confirmation number or PDF with the date and amount paid.
- Keep W-9s for contractors and prepare required information returns on time.
- Review retirement-plan deadlines with the plan provider before year end.
- Check IRS disaster-relief announcements and state guidance before relying on a standard date.
Extension and special-situation rules
A timely Form 4868 extension generally provides until October 15, 2026, to file a 2025 individual return. It does not postpone the April 15 payment deadline. Taxpayers abroad, combat-zone taxpayers, and taxpayers in federally declared disaster areas may receive different deadlines. Fiscal-year businesses also follow different schedules.
If your income is seasonal or uneven, the annualized-income installment method may better match payments to when income was earned. That method can require Form 2210 and Schedule AI with the return; do not simply move income between quarters without following the official method.
Frequently asked questions
What are the 2026 estimated tax deadlines?
For calendar-year individuals, the four 2026 Form 1040-ES dates are April 15, June 15, and September 15, 2026, and January 15, 2027.
Does a tax extension also extend the payment deadline?
No. A timely extension generally moves the federal filing deadline to October 15, 2026, but tax for 2025 was still due April 15, 2026.
Are state estimated taxes included with Form 1040-ES?
No. Form 1040-ES is federal. Pay state estimated taxes separately where required and check the state’s schedule.
What if a deadline falls on a weekend or legal holiday?
Generally, the due date moves to the next day that is not a Saturday, Sunday, or legal holiday. The published dates above already reflect the 2026 federal calendar.
