When Are Taxes Due In 2026 (Including Estimated Taxes)

Personal federal income taxes for the 2025 tax year (which you file in 2026) are due Wednesday, April 15, 2026.

Estimated quarterly tax payments are due April 15, June 15, September 15, 2026, and January 15, 2027.

If you operate a business entity (such as an S-corporation, partnership, or trust) your deadlines may fall earlier. Weekend or federal holiday shifts can move those dates, so always confirm the official IRS calendar before filing.

We also included the estimated tax deadlines for 2026, since making estimated tax payments can always be annoying.

Some states (including Hawaii, Iowa, and Louisiana) set different due dates, while others automatically extend if there are any disasters (which sadly happen semi-regularly).

Don’t forget to file your estimated taxes, if required, so that you can avoid penalties and interest.

Filing Your Taxes

Where and how should you file your taxes? Most tax software will handle annual income tax filings and extensions. Check here for the best tax software.

Note that some of the free tax filing software may not offer as much customer service as paid versions. If you want specific questions answered or need guidance from a real person, be sure to check that those services are offered with the software.

If your taxes are fairly simple, filing online or through tax software is not difficult and will save your money. If your taxes are on the more complex side or you just don’t want to deal with filing, you’ll need to hire a tax professional, which will be more costly.

Tax professionals can be found locally, or you can visit any of the large tax brands such as H&R Block. Both have physical locations that allow you to speak to someone in person and have your questions answered.

There are also tax counseling programs for the elderly, and volunteer income tax assistance (VITA) for low income families that need help. See this guide to free tax preparation.
