As we move into 2025, one of the most common financial questions Americans ask is: “When are taxes due in 2025?”
Whether you’re a first-time filer, a seasoned taxpayer, or a small business owner, understanding the IRS tax deadlines is essential to avoiding penalties and staying compliant.
This guide covers everything you need to know, from key dates and extension rules to state-specific details and frequently asked questions.
Federal Tax Deadline: April 15, 2025
The official IRS deadline for filing federal income tax returns in 2025 is Tuesday, April 15, 2025. This is commonly referred to as Tax Day.
Why April 15?
Tax Day typically falls on April 15 unless it lands on a weekend or a federal holiday. In 2025, April 15 falls on a Tuesday with no conflicting holidays, so the deadline remains unchanged.

What to Do If You Can’t File by April 15
If you’re unable to file your federal return by April 15, you can file for a six-month extension using IRS Form 4868. This extends your filing deadline to October 15, 2025.
However, it’s important to understand that a filing extension does not extend your payment deadline. You must estimate and pay any owed taxes by April 15 to avoid late payment penalties and interest charges.
Business Tax Filing Deadlines in 2025
Business structures have different filing deadlines. Here are some of the most important ones:

Deadlines for U.S. Citizens Living Abroad

State Tax Deadlines in 2025
While many states align with the federal deadline, some have their own tax filing schedules. It’s important to check with your state’s Department of Revenue or tax authority to confirm your specific deadline.
Frequently Asked Questions
When can I start filing my 2024 taxes in 2025?
The IRS typically begins accepting tax returns in mid-to-late January. For 2025, this is expected to be around January 20.
What happens if I miss the April 15 deadline and don’t file an extension?
You may be subject to a failure-to-file penalty, which can reach up to 25% of your unpaid taxes. There may also be additional interest and failure-to-pay penalties.
Can I still file taxes after April 15, 2025?

Will the tax deadline change if April 15 is a weekend or holiday?
Yes, if April 15 falls on a weekend or legal holiday, the deadline is moved to the next business day. In 2025, April 15 is a Tuesday, so the standard deadline applies.
