As 2026 begins, many taxpayers are asking the same question: when can you file your taxes? If you are filing a federal return for the 2025 tax year, the IRS officially opened the 2026 filing season on January 26, 2026. For most individual taxpayers, the main federal deadline to file and pay is April 15, 2026.
Knowing these dates early can help you avoid penalties, reduce stress, and plan ahead whether you are filing a personal return or a business return.
When does the 2026 tax season begin?
The IRS began accepting and processing federal individual income tax returns for tax year 2025 on January 26, 2026. Filing early can be helpful, especially if you expect a refund or want more time to fix any issues before the deadline.
If you plan to claim credits such as the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit (ACTC), it is important to know that the IRS cannot issue those refunds before mid-February by law. For many eligible early filers using direct deposit, the IRS said refunds were expected to be available by around March 2, 2026, assuming there were no other issues with the return.
Key dates to remember for personal taxes in 2026
For most calendar-year individual filers, these are the most important federal dates:
- January 26, 2026 – IRS filing season opens for 2025 federal individual returns.
- April 15, 2026 – Deadline to file your 2025 individual federal return and pay any tax due.
- October 15, 2026 – Extended filing deadline for taxpayers who properly request an extension by April 15. An extension gives more time to file, but not more time to pay.
If you need more time, filing an extension can help you avoid a late-filing penalty. But if you owe taxes, you should still pay as much as possible by April 15, 2026 to reduce penalties and interest.
When are business taxes due in 2026?
Business tax deadlines depend on the type of business.
C corporations that use a calendar year generally file by April 15, 2026.
S corporations and partnerships using a calendar year generally file by March 16, 2026, because March 15 falls on a Sunday in 2026.
Sole proprietors and many single-member LLCs usually report business income on their individual return, so their deadline generally follows the personal filing deadline of April 15, 2026.
Estimated tax payment deadlines for 2026
Taxpayers who are self-employed or who do not have enough tax withheld may also need to make estimated tax payments. Key 2026 estimated tax dates include:
- April 15, 2026 – First estimated tax payment for 2026.
- June 15, 2026 – Second estimated tax payment.
- September 15, 2026 – Third estimated tax payment.
- January 15, 2027 – Final estimated tax payment for 2026.
Staying on top of these dates is important because missing estimated payments can lead to penalties.
Tax credits and deductions to keep in mind
When preparing your return, it is worth reviewing the credits and deductions that may apply to you. Common examples include the Earned Income Tax Credit, education credits, and business deductions for eligible expenses. Taxpayers should always confirm eligibility based on the current IRS rules for the year they are filing.
For business owners, organized records of income, expenses, and estimated payments can make tax filing easier and help reduce errors. Electronic filing is also encouraged because it is generally faster and more accurate than paper filing.
How to prepare for the 2026 tax season
A smoother filing season usually starts with preparation. Gather your forms early, including W-2s, 1099s, and records for deductions or credits. If you own a business, make sure your books are current and your expenses are documented. Filing early, reviewing your return carefully, and getting professional help when needed can make the process much easier.
Final thoughts
For most taxpayers, the answer to “When can you file taxes in 2026?” is simple: the IRS started accepting 2025 individual returns on January 26, 2026, and the main federal deadline for most individuals is April 15, 2026. Business deadlines can come earlier depending on the entity type, so planning ahead is important.
If you want to avoid stress, late filing, and missed opportunities, it is a good idea to organize your records early and speak with a qualified tax professional if your situation is more complex.
