When does the 2026 tax season start?
The 2026 federal tax filing season — for tax year 2025 returns — officially begins on January 26, 2026. This is when the IRS starts accepting and processing tax returns.

Major tax law changes for 2026
The One Big Beautiful Bill Act (OBBBA) — passed in July 2025 — introduced significant changes impacting the 2025 tax year returns filed in 2026.
These changes include new deductions, expanded tax credits, and inflation-adjusted rules that could lower tax liability or increase your refund.
Key updates include:
- Increased state and local tax (SALT) deduction cap up to $40,000 for certain taxpayers.
- New deductions for qualified overtime and tip income, potentially reducing taxable income for many workers.
- A temporary senior deduction of up to $6,000 for eligible taxpayers age 65 and older.
- Adjustments to digital asset reporting, which may affect those holding or selling cryptocurrencies.

Tips for Preparing Before Filing
To make filing smoother and possibly maximize your refund, consider the following pre‑season preparation tips:
Collect all tax documents early.
Gather your W‑2s, 1099s, 1098s, and other income forms as soon as you receive them. Your employer and clients must send these forms by the end of January.
Use IRS online tools.
IRS.gov offers resources such as the Interactive Tax Assistant, account management tools, and tax help pages to answer common questions.
Choose direct deposit.
The IRS is phasing out paper checks, so direct deposit of your refund into your bank account is strongly recommended.
The 2026 tax season brings several important changes and deadlines that taxpayers must understand before filing their 2025 tax returns.
With the official start on January 26, 2026, and a filing deadline of April 15, preparing early, knowing changes under the One Big Beautiful Bill, and using IRS resources will help make your tax filing process smoother and possibly increase your refund.
Stay informed and organized to avoid penalties and take advantage of new deductions and credits for the year.
