For the 2023 tax year, the standard federal estimated income tax due dates for calendar‑year individuals were:

  • 1st payment (income from Jan 1–Mar 31, 2023): April 18, 2023.
  • 2nd payment (income from Apr 1–May 31, 2023): June 15, 2023.
  • 3rd payment (income from Jun 1–Aug 31, 2023): September 15, 2023.
  • 4th payment (income from Sep 1–Dec 31, 2023): January 16, 2024.

These dates differ slightly from the general IRS pattern (normally April 15, June 15, September 15, and January 15 of the following year) because in 2023 the usual April 15 deadline was pushed to April 18 due to the weekend and Emancipation Day holiday in Washington, D.C..

Payment # Income period covered Due date Notes
1st Jan 1 – Mar 31, 2023 April 18, 2023 Shifted from April 15 because of weekend and D.C. Emancipation Day holiday
2nd Apr 1 – May 31, 2023 June 15, 2023 Standard 2nd‑quarter pattern
3rd Jun 1 – Aug 31, 2023 September 15, 2023 Standard 3rd‑quarter pattern
4th Sep 1 – Dec 31, 2023 January 16, 2024 Normally Jan 15, but moved because of the weekend/holiday timing

How this fits the usual IRS pattern

The IRS “default” schedule for individuals on a calendar year is:

  • Income Jan 1–Mar 31 → due April 15.
  • [7]
  • Income Apr 1–May 31 → due June 15.
  • [7]
  • Income Jun 1–Aug 31 → due September 15.
  • [7]
  • Income Sep 1–Dec 31 → due January 15 of the following year.

Whenever one of those dates lands on a weekend or federal/D.C. holiday, the deadline moves to the next business day, which is what happened with April 18, 2023 and January 16, 2024.

Practical tips for 2023 payments

  1. Check if you needed to pay: You generally owe estimated tax if you expect to owe at least a certain minimum amount when you file and your withholding is not enough; the IRS has detailed thresholds and safe‑harbor rules in its guidance.
  2. [8]
  3. Use the “safe harbor” rules: Many taxpayers avoid penalties by paying 100% (or 110% at higher incomes) of their prior‑year tax, spread over the four dates, even if current‑year income is higher.
  4. [8]
  5. Use IRS Direct Pay or EFTPS: These systems let you schedule or make same‑day estimated payments online and get confirmation numbers for your records.
  6. [8]
  7. Watch for special disaster relief: In some years, people in federally declared disaster areas get extended estimated‑tax deadlines, so checking IRS news releases can matter if you live in an affected area.

Forum-style perspective & “latest news” angle

“I thought I could just settle up at filing, but turns out the IRS expects you to pay as you go. I got dinged with a penalty for missing the June 15 date for 2023.”[8]

Discussion in tax blogs and financial sites around the 2023 filing season often highlighted that more gig‑workers and creators were getting caught by estimated‑tax rules, especially after income spikes from side hustles in 2022–2023. Many advisors emphasized automating quarterly payments or increasing W‑2 withholding to avoid surprises.
