IRS Sets January 26, 2026 as the Official Filing Season Start
The IRS has set January 26, 2026 as the date when it will begin accepting and processing federal individual income tax returns for the 2025 tax year. This is the official opening day of the 2026 filing season for individual taxpayers across the United States.
On this day, the IRS’s systems will go live and start processing returns submitted by taxpayers and tax professionals. The IRS Free File Fillable Forms option also becomes available on this date, giving taxpayers a free way to prepare and file their federal return electronically if they choose to do so.
Beginning tax filing at the official start date means the IRS will actively accept your return into its systems, begin processing it, and trigger any timeline for issuing refunds if you are entitled to one. Filing before the opening date does not count as official filing—the IRS will hold those submissions until the system opens.
IRS Free File Program Opens Early for Some Taxpayers
While January 26, 2026 is the general start date for most taxpayers, a key exception exists for eligible individuals through the IRS Free File program. The Free File program typically opens earlier than the general filing season for taxpayers with an adjusted gross income (AGI) at or below a specified limit, allowing these filers to submit returns using partner tax preparation software.
For the 2026 tax season, certain taxpayers qualify to begin submitting their returns through the Free File program as early as January 9, 2026. This early window gives eligible taxpayers the ability to prepare and electronically submit their returns before the official IRS processing systems go live. Once the official start date arrives, any returns submitted through the Free File platform will be accepted and processed.
Using Free File can reduce costs for many taxpayers and encourage earlier filing, which may help smooth out peak filing period delays.
IRS Filing Deadline and Extended Deadlines You Must Know
Once the IRS begins accepting returns on January 26, 2026, the broader calendar of deadlines for the tax season unfolds:
April 15, 2026 is the standard deadline for individual federal tax returns. Almost all taxpayers must file their returns or request an extension by this date, and any tax owed must be paid by April 15 to avoid penalties and interest.
If taxpayers cannot complete their returns by April 15, they can file for an extension. The extended deadline to file the return is October 15, 2026. It is important to note that an extension to file does not extend the deadline to pay any taxes owed. Taxpayers must estimate and pay any balance due by April 15 to avoid late payment penalties and interest.
Meeting these deadlines is essential for compliance and to protect your financial standing.
What You Need to File Once the IRS Accepts Returns
Before the IRS will accept your tax return, you must gather several important documents and pieces of information. These commonly include:
- Wage and income statements such as W-2s and 1099s
- Social Security numbers and dates of birth for you, your spouse, and dependents
- Records of interest, dividend, and investment income
- Documentation for deductions such as mortgage interest, student loan interest, and charitable donations
- Proof of health insurance coverage if applicable
- Bank account and routing number for direct deposit of refunds
Having all necessary documents ready before January 26 ensures you won’t delay filing and can take full advantage of the earliest processing possible.
Electronic Filing: The Fastest Way to Submit Your Return
Electronic filing (e-file) is now the most popular and efficient method for submitting a federal tax return. On January 26, 2026, the IRS will begin accepting e-filed returns for the 2025 tax year.
E-filing offers several advantages over paper filing:
- Faster processing times
- Reduced risk of errors due to built-in software checks
- Ability to track the status of your return electronically
- Refunds issued more quickly, especially with direct deposit
Most major tax preparation software platforms and tax professionals will allow taxpayers to complete their returns before the IRS’s official acceptance date and then transmit them as soon as the IRS systems open. This means your return is ready to be accepted right when filing begins.
Timing Your Refund After the IRS Accepts Your Return
Once the IRS starts processing returns on January 26, taxpayers who file electronically and choose direct deposit generally receive their refunds within roughly 10 to 21 days after the return is accepted. However, actual timing varies based on factors such as return accuracy, whether you claim refundable credits, and the volume of filings.
Certain refundable credits, including the Earned Income Tax Credit (EITC) and the Additional Child Tax Credit (ACTC), may delay a refund until later in the season due to verification requirements. For taxpayers who claim these credits, refunds typically arrive later in February or early March after the IRS has completed additional verification steps.
If you file a paper return by mail, expect processing and refund delivery to take significantly longer — often 6 to 8 weeks or more — because all elements must be handled manually.
Choosing direct deposit is widely recommended, as the IRS has phased out paper refund checks for many taxpayers and direct deposit leads to faster, more secure refund delivery.
Business Tax Returns Open Earlier in January
While individual returns must wait until January 26 to be accepted, certain business tax returns begin to open earlier. For the 2026 filing season:
- Many business tax returns can begin to be e-filed as early as January 13, 2026.
- Forms for estates, trusts, and other specialized business filings also become available in mid-January.
This early availability gives business owners, accountants, and tax professionals a head start on business-related filings, leaving individual returns to be managed once the official IRS acceptance window opens later in January.
Changes in Tax Law Affecting 2026 Filing Season
The 2026 tax filing season reflects recent tax law changes that affect filing and refund outcomes. New rules may change the way certain types of income are reported, revise deductions, and modify credits.
Many taxpayers may benefit from expanded deductions on overtime income, tip income, and interest on certain expenses. Because these rules have shifted from prior tax years, taxpayers should review the instructions for their forms carefully and ensure that any eligible deductions or credits are correctly applied.
Tax preparation software and qualified tax professionals will incorporate these changes into their processes, but individual filers should still confirm that their returns reflect the most current law.
Avoid These Common Filing Mistakes
Errors on your tax return can cause delays in processing, incorrect refund amounts, or unnecessary IRS correspondence. To avoid common mistakes:
- Double-check Social Security numbers and names
- Verify income figures match the amounts on your W-2s and 1099s
- Confirm your direct deposit information for refunds
- Ensure you include all required forms and schedules
- Review any claimed credits and deductions for eligibility
Taking time to review your completed return — or working with a trusted tax professional — can reduce errors and streamline IRS acceptance once the filing season opens.
Free Filing Options for Eligible Taxpayers
Taxpayers with limited income may qualify for free preparation and filing assistance. These include:
- The IRS Free File program (eligibility based on income limits)
- Volunteer Income Tax Assistance (VITA) for qualifying low- and moderate-income taxpayers
- Tax Counseling for the Elderly (TCE) for seniors
- Software providers offering certain free versions of tax preparation products
If you qualify, these free resources can significantly reduce the cost of tax preparation and help you submit your return as soon as the IRS starts accepting returns.
IRS Tools to Help You Track and Prepare Your Return
The IRS provides online tools that become especially useful once the filing season starts. These include:
- Refund status checks to see when your refund is issued
- Your IRS online account for viewing past payments and balances
- Interactive tools that help estimate refund amounts and answer tax questions
Using these tools once the IRS begins processing on January 26 allows you to monitor progress and manage your tax record securely.
What Happens After You File
After the IRS accepts your return, it begins processing and verifying the information. If the return is accepted without issues, refund timing starts. In cases where the IRS needs additional information or identifies potential errors, they may contact you by mail.
Keep copies of all tax documents and your filed return in case follow-up is needed. Promptly respond to any IRS correspondence to avoid further delays.
Preparing for Future Tax Seasons
Getting familiar with the IRS calendar once the agency has started accepting returns gives you an advantage in future years. Tracking deadlines, organizing information, and understanding how your financial year impacts your return will make future filing more efficient.
Preparing early, especially before the IRS opens for the season, allows you to take advantage of early tax planning strategies and reduce stress as deadlines approach.
Your Best Strategy as the IRS Accepts Returns
When the IRS opens its systems on January 26, 2026, make sure you are ready with accurate documents, correct information, and your chosen filing method. Filing early can speed up refund delivery, give you time to correct any issues, and minimize last-minute filing stress before the April 15 deadline.
Whether you choose electronic filing, work with a tax professional, or take advantage of free filing options, understanding the timeline and preparing ahead ensures you make the most of the upcoming filing season.
