IRS Officially Opens 2026 Tax Filing Season: What Taxpayers Need to Know

The Internal Revenue Service has officially opened the 2026 federal tax filing season, marking the start of the annual process for individuals and businesses to file 2025 tax year returns. For taxpayers and advisors, the opening of filing season signals more than just a deadline on the calendar. It sets the tone for compliance, planning, and cash flow decisions in the months ahead.

This year’s tax season is particularly important due to recent federal tax law changes, new reporting requirements, and adjustments to IRS processing procedures. Understanding how these updates apply can help taxpayers avoid delays, maximize available tax benefits, and reduce the risk of notices or amended returns later in the year.

2026 Tax Filing Season: Key Dates and What to Expect

The IRS began accepting and processing federal income tax returns in late January, giving taxpayers several months to prepare and file before the April 15 federal deadline. Extensions remain available for those who need additional time, though any tax due must still be paid by the deadline to avoid penalties and interest.

The agency expects to process more than 160 million individual returns this filing season. With volumes at this level, filing early remains one of the most effective ways to minimize delays, especially for taxpayers expecting refunds or claiming credits that require additional review.

For CPAs and tax professionals, the opening of filing season also means IRS systems are fully operational. E-file platforms, refund-tracking tools, and online taxpayer accounts are now live, making it easier to resolve issues early before peak-season congestion.

New Tax Law Changes Shaping the 2026 Filing Season

The 2026 filing season is the first full season to reflect major changes enacted under recent federal tax legislation. These updates affect both individual and business taxpayers and can significantly alter final tax liability.

Key changes taxpayers should understand include:

• Higher standard deduction amounts, which reduce taxable income for millions of filers and simplify returns for those who no longer itemize.

• Expanded child and family-related credits, increasing potential refunds for qualifying households and changing eligibility thresholds that must be carefully reviewed.

• New income adjustments for workers, including exclusions for certain overtime pay and tips, which are especially relevant for hourly and service-industry employees.

• A higher SALT deduction cap, offering temporary relief to taxpayers in higher-tax states but requiring careful coordination between federal and state filings.

Because these provisions are new, documentation and accuracy are more important than ever. Many taxpayers will benefit, but only if the rules are applied correctly.

Updated Forms and Expanded Reporting Requirements

Several IRS forms have been revised or newly introduced to support the expanded deductions and credits available this year. Additional schedules now require taxpayers to separately report income adjustments and exclusions, increasing the importance of proper classification.

Information reporting continues to expand as well. Taxpayers receiving income through payment apps, online marketplaces, or digital assets must ensure that all reporting documents are collected and reconciled before filing. Mismatches between reported income and IRS records remain one of the most common causes of refund delays and notices.

This growing complexity is one reason many firms are relying on real-time tax intelligence platforms like Bizora to stay ahead of regulatory changes as they happen, rather than reacting after filing season is already underway.

Filing Options and Refund Processing Updates

Electronic filing remains the fastest and most accurate way to submit a return. Taxpayers who e-file and choose direct deposit typically receive refunds much faster than those who file on paper.

The IRS continues to emphasize direct deposit as the primary refund delivery method. Paper checks are increasingly limited, making it important for taxpayers to confirm bank account information before submitting their returns.

In most cases, refunds are issued within 21 days, provided the return is complete and accurate and not subject to additional review related to credits or identity verification.

Practical Tips for a Smooth Filing Season

To reduce errors and avoid unnecessary delays, taxpayers should:

• Gather all income statements and deduction records before filing

• Verify names, Social Security numbers, and banking information

• Confirm eligibility for new or expanded credits and deductions

• File early to avoid peak-season processing backlogs

• Seek professional guidance when dealing with complex income or business activity

For businesses, coordination between payroll, accounting, and tax reporting is especially important this year due to changes affecting compensation, deductions, and information returns.

Staying current with IRS guidance throughout the season can be challenging, which is why many tax professionals rely on Bizora for timely tax updates that translate regulatory changes into clear planning insights.
