What this calculator helps with
Use this page to translate a tax date into a practical countdown. It is especially useful when comparing the regular filing deadline, extension deadline, estimated tax payment dates or a custom deadline.
Deadline checklist
- Confirm whether the deadline is federal, state or local.
- Check whether an extension applies to filing only or also payment.
- Save proof of filing, payment and extension confirmations.
- Check disaster relief extensions if your area was affected.
Limitations
This tool does not calculate penalties, interest, refunds or tax owed. It also does not know your state, disaster relief status, fiscal year or business entity type.

FAQ
Is this official tax advice?
No. It is a date planning tool.
Does an extension give more time to pay?
Often an extension gives more time to file, not necessarily more time to pay. Verify your situation.
Can state deadlines differ?
Yes. State deadlines, disaster relief and local rules may differ from federal dates.
