Federal tax rules change every year, but 2025 includes several important updates that may affect how much you owe, which credits you qualify for, and what documentation is required when you file in 2026.
Some changes come from annual IRS inflation adjustments, while others are the result of new federal legislation, including the One Big Beautiful Bill.
This page highlights the most important tax law changes affecting 2025 tax returns, so you know what to watch for this filing season.
What Changed for Individual Taxpayers in 2025
Income Exclusions
New rules may allow some taxpayers to exclude certain income, including:
- Tips
- Overtime wages
- Certain vehicle loan interest
Eligibility rules apply and income limits may affect qualification.
Itemized Deductions and SALT Limits
The State and Local Tax (SALT) deduction cap remains an important factor for taxpayers who itemize, especially homeowners and high-income earners.
Changes under recent legislation may affect:
- How much state income tax you can deduct
- Property tax deduction planning
- Whether itemizing is still beneficial
Family and Dependent Credits
Several family-focused credits were expanded or adjusted, including:
- Adoption tax credit provisions
- Working family benefit structures
- Certain dependency-related deductions
These may change refund amounts and eligibility thresholds.
What Changed for Business Owners in 2025
Qualified Business Income (QBI) Deduction
The 20% QBI deduction remains available for many pass-through businesses, but:
- Income thresholds still apply
- Industry limitations affect some professions
- Accurate income classification is essential
Business Credits and Incentives
Changes affecting businesses include:
- New limits on Employee Retention Credit claims
- Clean energy credit expirations
- Adjustments to manufacturing and development incentives
Businesses engaged in R&D, production, or clean energy may still qualify for targeted credits.
New Compliance and Reporting Rules for Businesses
Some legal obligations affect business owners even if they do not change tax calculations.
Corporate Transparency Act (BOI Reporting)
Many businesses must now file Beneficial Ownership Information (BOI) reports with FinCEN.
This requirement is separate from tax filing but applies to many small businesses and LLCs operating in 2025.
Failure to comply can result in penalties.
