The year 2025 is bringing several significant updates to U.S. tax laws, affecting individuals, businesses, and tax professionals. If you’re a CPA or tax preparer, staying informed on these changes will be crucial to ensuring compliance and maximizing tax benefits for your clients. Below, we break down the most important legislative tax changes coming in 2025.
1. Standard Deduction Increases
One of the most universal changes is the increase in the standard deduction, which will benefit most taxpayers who don’t itemize:
- Single filers: $15,000 (up from $14,600 in 2024)
- Married filing jointly: $30,000 (up from $29,200 in 2024)
- Heads of household: $22,500 (up from $21,900 in 2024)
This increase helps offset inflation and allows taxpayers to reduce their taxable income further.
2. Adjustments in Income Tax Brackets
The IRS has adjusted federal income tax brackets to account for inflation. The highest 37% tax rate now applies to:
- Single filers earning over $626,350 (previously $609,350)
- Married filing jointly earning over $751,600 (previously $731,200)
These adjustments mean that some taxpayers may fall into a lower tax bracket and see slight reductions in their tax bills.
3. Changes to Capital Gains Tax Brackets
Long-term capital gains tax brackets have also been revised:
- 0% rate: Income up to $47,025 for single filers ($94,050 for married filing jointly)
- 15% rate: Income between $47,026 and $518,900 for single filers ($94,051 to $583,750 for married filing jointly)
- 20% rate: Income exceeding $518,900 (single) or $583,750 (joint)
This represents a slight increase from 2024, allowing some taxpayers to remain in a lower bracket and pay less in capital gains taxes.
4. Retirement Contribution Increases
Under the SECURE 2.0 Act, several retirement savings changes are coming in 2025:
- 401(k), 403(b), and 457 plan contribution limit: Increased to $23,500 (up from $23,000)
- Catch-up contributions (age 50+): Remain at $7,500, except for those aged 60-63, who can now contribute up to $11,250
- IRA contribution limits: Stay at $7,000, with the catch-up contribution remaining at $1,000
Additionally, income limits for Roth IRA contributions have increased:
- Single filers: Phase-out begins at $150,000 (up from $146,000)
- Married filing jointly: Phase-out begins at $236,000 (up from $230,000).
5. Section 179 Deduction for Businesses
For small businesses, the Section 179 deduction—which allows for immediate expensing of equipment purchases—has increased:
- Maximum deduction: $1,160,000 (up from $1,080,000 in 2024)
- Phase-out threshold: $2,890,000 (up from $2,700,000 in 2024)
This increase provides a greater tax break for businesses investing in new equipment.
6. Alternative Minimum Tax (AMT) Adjustments
The AMT exemption has been raised:
- Single filers: $88,100 (up from $85,700)
- Married filing jointly: $137,000 (up from $133,300)
This change may prevent some middle-income taxpayers from being subject to the AMT.
7. Tax Credits Updates
Earned Income Tax Credit (EITC)
- The maximum credit for families with three or more children is increasing to $8,046 (up from $7,430).
Child Tax Credit
- Remains at $2,000 per child, with a refundable portion of $1,700 (up from $1,500).
Clean Energy Tax Credits
- Clean Vehicle Credit: Up to $7,500 for new electric vehicles and $4,000 for used EVs.
- Expanded eligibility for home energy credits, incentivizing residential solar panel and energy-efficient appliance installations.
8. Estate and Gift Tax Adjustments
- The estate tax exemption is increasing to $13.99 million (up from $13.61 million in 2024), allowing more assets to pass tax-free to heirs.
- The annual gift tax exclusion has been raised to $19,000 per recipient (up from $18,000).
9. Foreign Earned Income Exclusion
Americans working abroad can now exclude up to $130,000 of foreign-earned income, up from $126,500 in 2024.
10. Expiration of the Tax Cuts and Jobs Act (TCJA) Looming in 2025
While not an immediate change, the Tax Cuts and Jobs Act (TCJA)—which lowered individual tax rates and doubled the standard deduction—is set to expire at the end of 2025. This could lead to:
- Higher individual income tax rates
- A return to lower standard deductions
- The return of personal exemptions
Congress will need to decide whether to extend, modify, or let these provisions lapse.
Final Thoughts
The tax landscape in 2025 brings both opportunities and challenges for individuals and businesses. CPAs and tax preparers should be prepared to navigate these changes to maximize deductions and credits for their clients.
For businesses, higher Section 179 limits and new retirement contribution rules present planning opportunities. For individuals, adjustments to tax brackets, credits, and the AMT exemption could mean tax savings. However, the possible expiration of the Tax Cuts and Jobs Act remains a major uncertainty for 2026.
Staying updated on these changes will ensure compliance and strategic tax planning. If you need assistance preparing tax returns under these new rules, consider outsourcing your tax preparation to experts at OBS who are well-versed in the latest tax laws.
