The 2026 tax season officially opens on January 26, 2026, when the Internal Revenue Service begins accepting electronic tax returns for the 2025 tax year. While filing season always brings deadlines and paperwork, this year includes significant tax changes that may directly affect your return.

From expanded deductions under the One, Big, Beautiful Bill (OBBB) to inflation-adjusted tax brackets and higher contribution limits, understanding what’s new before you file can make a real difference.

Key Tax Changes Impacting 2026 Filings

One, Big, Beautiful Bill (OBBB) Provisions

Several provisions of the One, Big, Beautiful Bill are now in effect for tax years 2025 through 2028, including:

  • Personal vehicle loan interest deduction Taxpayers may be eligible to deduct up to $10,000 in interest paid on qualifying personal vehicle loans.
  • 100% bonus depreciation Businesses may immediately expense the full cost of qualifying property rather than depreciating it over time.

These updates create new opportunities—but also add complexity. Eligibility rules, income limits, and proper reporting are key to claiming these benefits correctly.

Inflation Adjustments for Tax Year 2026

The IRS has adjusted tax brackets and more than 60 tax provisions for inflation. These updates can affect:

  • Income tax brackets
  • Standard deductions
  • Credits and phase-out thresholds

Even small changes in these areas can impact how much you owe or how much you get back, particularly if your income changed during 2025.

Higher Retirement Contribution Limits

For the 2026 tax year, 401(k) contribution limits increase to $24,500, offering expanded tax-deferred savings opportunities for individuals planning ahead.

Proper contribution timing and coordination with other deductions can play an important role in overall tax planning.

IRS Interest Rates to Be Aware Of

The IRS interest rate on overpayments and underpayments is 7% for the 2026 filing season. This makes accurate filing and proper payment planning more important than ever.

Avoiding surprises starts with understanding your tax position before filing—not after.

Why 2026 Filing Deserves a Closer Look

Between OBBB changes, inflation adjustments, higher limits, and evolving filing rules, the 2026 tax season is not a one-size-fits-all filing year.

What worked last year may not apply this year—and missing a deduction or misapplying a new rule can cost more than expected.
