The 2025 tax season will be kicking off in a few short weeks. Here are all the important tax deadlines you need to know for the upcoming year.
When Are Federal Income Taxes Due?
Your federal income tax return must be filed no later than April 15, 2025. Those who reside in a FEMA disaster area may have additional time to file. You can check to see if your area has an alternate filing deadline by visiting IRS.gov.
State Income Tax Filing Deadlines
Those residing in Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming do not have a state income tax so no returns are required. The majority of other states, however, have the same April 15 deadline as the IRS. There are a few exceptions, including:
- Delaware – April 30, 2025
- Hawaii – April 20, 2025
- Iowa – April 30, 2025
- Louisiana – May 15, 2025
- Virginia – May 1, 2025
Do Businesses Have Different Federal Filing Deadlines?
Depending on the type of business entity you have in place, and which tax year you use (calendar or fiscal), your federal filing deadline may land on a different date than your personal tax filing deadline.
- Sole Proprietor. Your business income is reported on Schedule C. This is submitted with your Form 1040 by the April 15 deadline.
- Partnership. Partnerships must report their income and expenses on IRS Form 1065 by the 15th day of the third month after the end of their tax year. For those using the calendar year (January 1 – December 31), that’s March 17, 2025, because March 15 lands on a weekend. If you operate on a fiscal year, the date will vary by your end date. For example, those ending August 31 must file Form 1065 by November 30. The shareholders, however, actually pay the business taxes. Each must submit Schedule K-1 with their personal income tax return by the April 15 deadline and pay their share of the taxes.
- S Corporation. Similar to partnerships, S-corporation shareholders are responsible for paying the business taxes and must submit Schedule K-1 with their personal returns. The business is also required to report its income and expenses on Form 1120S. For those operating on the calendar year, the deadline is March 17, 2025. Fiscal year deadline dates will vary.
- C Corporation. C corporations are subject to double taxation. The business (if using the calendar year) must file Form 1120 and pay the flat corporate income tax rate (21%) by April 15, 2025. If using a fiscal year, Form 1120 must be filed by the 15th day of the fourth month after the end of your tax year. The one exception to this rule is those with a fiscal year ending on June 30. In that case, your Form 1120 must be submitted by September 15. Shareholders are taxed on earnings when they file their personal income tax returns on April 15.
In addition to federal income tax filing, you may also be required to file state income tax returns for your business. Check with your state’s Department of Revenue to confirm its deadline date.
2025 Estimated Quarterly Tax Dates
Independent contractors, freelancers, and other self-employed taxpayers are typically required to make quarterly tax payments throughout the year to avoid an IRS underpayment penalty. You should also make estimated quarterly tax payments if you expect to owe more than $1,000 in taxes when you file in 2026. The deadline dates for 2025 quarterly tax payments are as follows:
- April 15, 2025
- June 17, 2025
- September 16, 2025
- January 15, 2026
You can make your payments online, through the IRS2Go app, or by mail using Form 1040-ES.
When is The Last Date to Request a Filing Extension?
If you are unable to file your federal income tax return by the deadline, you must request a filing extension before midnight on April 15, 2025. Simply complete Form 4868 using online tax software or submit it by mail. You can also request an automatic extension using the IRS Free File tool. Another option is to make a partial or whole payment for your taxes due and indicate it’s for a filing extension. Once approved, your filing deadline will be pushed back 6 months to October 15, 2025. Businesses (LLCs, partnerships, and corporations) can request a 6-month filing extension by submitting IRS Form 7004.
Please note that requesting an extension gives you more time to file. It does not extend your time to pay your taxes. Any taxes paid after the original filing deadline are considered late and subject to penalties and interest fees.
When Will The IRS Issue My Refund?
Generally, the IRS issues refunds within three weeks (21 days) if you file online. Those filing by paper may have to wait up to 12 weeks. Requesting direct deposit instead of a check will expedite the process. Filing earlier in the season also speeds things up. If you claim the Earned Income Tax Credit (EITC) or Additional Child Tax Credit (ACTC), your refund will not be disbursed until after mid-February.
You can check the status of your tax refund by using the “Where’s My Refund?” tool on the IRS website. Please wait at least 24 hours if you file online or one month if you file by mail.
