This IRS tax deadlines article has been updated for the 2025 tax season (including deadlines for 2024 tax year filings). Tax season has arrived. This article will cover important key dates for the 2025 tax season, including the tax filing start date, tax deadline, extension filing deadline, extended deadline, estimated tax payment deadlines, a 2025 tax season calendar, and much more (even some discounted tax software at the end).
When is the 2025 Tax Deadline for Tax Filing (for the 2024 Tax Year)?
The IRS tax deadline to file your tax return will be Tuesday, April 15, 2025, according to the IRS.
Some specifics states or locales will see their tax deadline date extended as relief to natural disasters. Check the IRS disaster relief page for further details.
Tax Filing Postmark & E-File Deadline
The Tuesday, April 15 tax deadline does not refer to when the IRS receives mailed tax returns. Instead, it refers to the date that the tax return is postmarked. So if you mail out your tax return on April 15 by USPS mail and the IRS receives your tax return after that date, your return won’t be considered late. The same rule applies for e-filing your taxes. If you e-file your taxes, you must do so by April 15 as well.
Note: the HSA Contribution Deadline and IRA Contribution Deadline are the Same as the Tax Deadline
Note that the HSA contribution deadline and IRA contribution deadline also fall on the same day as the tax deadline. This means you have a few additional months to make contributions for the tax and calendar year, beyond the actual tax and calendar year end date. You can also open new accounts to contribute to up until the same date, which is great news for savers.
When is the Tax Deadline if “Out of the Country” in 2024?
Your tax filing deadline and payment deadline, if you are “out of country”, is Monday, June 16, 2025 (normally June 15, but that falls on a Sunday in 2025). If you are out of country, you typically have an additional two months to file your taxes (from the typical April 15 date). Those eligible for this later date include:
- Those who live outside the United States and Puerto Rico and main place of work is outside the United States and Puerto Rico, or
- Those in military or naval service outside the United States and Puerto Rico (there is additional lenience for those in a combat zone, contingent operation, or who have been hospitalized).
If you qualify as being out of the country, you will still be eligible for the extension even if you are physically present in the United States. You must attach a statement to your return explaining which of the two situations qualify you for the extension.
Tax Extension Application Filing Deadline for 2024 Returns in 2025
If, for one reason or another, you are unable to file your tax return by the April 15, 2025 tax deadline for 2024 tax year returns, you can file for an IRS tax extension. Note that the extension must be postmarked by the April 15 deadline also.
Also, a key disclaimer – an extension of time to file is not an extension of time to pay. Any taxes due are still due on the normal filing deadline date, in order to avoid penalty.
How to File a Tax Extension – and the Extended Filing Tax Deadline for 2024 Returns in 2025
To file a tax extension, you will need to fill out IRS form 4868. Note that filing the extension does not get you off the hook, you still need to pay any estimated taxes by the April 15 deadline. If you don’t you will owe interest and possibly a penalty on your taxes owed.
The tax extension will allow you to push back the deadline for sending in your 1040 by 6 months (4 months if you are out of the country). If you’re in country, the extended tax filing deadline is Wednesday, October 15, 2025.
What are the Estimated Tax Payment Deadlines in 2025?
If you make estimated tax payments quarterly, due to earning contractual or self-employed income, here are the quarterly estimated payment deadlines in 2025:
| Quarter: | Time Period: | Estimated Tax Payment Deadlines (2024): |
|---|---|---|
| Q4, 2024 | September 1, 2024 - December 31, 2024 | January 15, 2025 |
| Q1, 2025 | January 1, 2025 - March 31, 2025 | April 15, 2025 |
| Q2, 2025 | April 1, 2025 - May 31, 2025 | June 16, 2025 |
| Q3, 2025 | June 1, 2025 - August 31, 2025 | September 15, 2025 |
| Q4, 2025 | September 1, 2025 - December 31, 2025 | January 15, 2026 |
When is the Tax Filing Start Date?
The tax filing start date for 2024 tax returns will be Monday, January 27, 2025. You can start working on your taxes sooner, however, software companies will hold your returns and cannot submit them to the IRS electronically via e-filing until the tax filing start date. Paper tax returns will begin processing at the same time. Your return will not be processed prior to, and you won’t receive your refund until after your return is processed.
I would recommend not filing a return sooner than the tax filing start date, because tax software companies will often update their software to take in to account any IRS changes.

Do I Need to File a Tax Return?
You may be wondering “Do I need to file taxes?“. It’s a fair question. There may be scenarios where you do not need to file taxes, including if your income is below certain minimum income thresholds. However, even in those scenarios, it could still be advantageous to file a return, as you may be eligible for refundable tax credits.
What if I File an Incorrect or Incomplete Return?
If you’ve already filed your taxes, but later found your return to be incorrect or incomplete, here is how to file an amended tax return with the IRS. You may also need to file an amended state return.
When will I Get My Refund?
As a standard, the IRS anticipates issuing more than nine out of 10 refunds in less than 21 days.
However, a newer law requires the IRS to hold refunds on tax returns claiming the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit until mid-February. Under the change required by Congress in the Protecting Americans from Tax Hikes (PATH) Act, the IRS must hold the entire refund — even the portion not associated with the EITC and ACTC — until at least Feb. 15. This change helps ensure that taxpayers get the refund they are owed by giving the IRS more time to help detect and prevent fraud.
After filing, you can always check your tax refund status to see where your refund is at.
