Official sources

What to gather

  • Current-year income estimate
  • Any estimated taxes already paid
  • Prior filing notes if you are also catching up

Best first move

Mark the next filing or estimated-tax deadline that affects you, then work backwards into what still needs to be gathered or saved before that date arrives.

Next steps

  1. Review the quarter or filing deadline that is nearest.
  2. Decide whether the issue is filing, payment, or both.
  3. Use the planner, extension, or payment-help pages that match the real issue.

Why deadline maps help

Seeing the timing structure in one place can stop people from mixing annual filing deadlines with quarterly payment timing.

How to use this page

Use it as a navigation page first, then jump into the specific due-date, extension, or payment page that matches your real question.
