When Are Taxes Due in 2025? Key Deadlines You Need to Know

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.

IRS Tax Calendar for 2025: Key Dates

Here’s a breakdown of the most important federal tax-related deadlines for individuals and businesses in 2025:

*Note: IRS start date for accepting returns may vary slightly and is usually announced in early January.

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:

Partnerships and S Corporations: Returns due by March 17, 2025
C Corporations: Returns due by April 15, 2025
Quarterly Estimated Taxes: Due April 15, June 17, September 15, and January 15, 2026 (for Q4 2025 income)

Deadlines for U.S. Citizens Living Abroad

U.S. citizens or resident aliens who live and work outside the United States on April 15 receive an automatic two-month extension to file their tax return. Their deadline is extended to June 15, 2025. However, taxes owed are still due by April 15, 2025.

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?

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.
