2025 Tax Planning: Why Charitable Giving and SALT Deductions Deserve a Closer Look

Smart 2025 tax planning moves:  

 

Charitable giving and SALT deductions offer meaningful opportunities for smart 2025 tax planning before several new federal limits begin in 2026. Acting now can help you preserve valuable deductions and make next year’s tax season a little lighter.  

Key changes to focus on: the SALT cap is $40,000 for 2025 (with a phase-down above $500,000 modified adjusted gross income (MAGI)), and a new 0.5% adjusted gross income (AGI) floor on charitable deductions begins in 2026. 

 

Why focus on 2025 tax planning now? 

As 2026 approaches, thoughtful 2025 tax planning can make a meaningful difference in how much of your income you keep. Two areas—charitable giving and state and local tax (SALT) deductions—stand out as important opportunities to act on before the 0.5% charitable floor and the new cap on the value of itemized deductions for top-bracket taxpayers apply in 2026.  Both involve timing decisions that don’t require spending more; just planning ahead. 

 

How can charitable giving strengthen your 2025 tax planning? 

Starting in 2026, charitable deductions will face a new limitation. Only donations that exceed 0.5% of your adjusted gross income (AGI) will count toward your itemized deduction. 

In simple terms, the first slice of your giving each year—0.5% of your income—will no longer be deductible. 

That makes 2025 the last year you can deduct every dollar you give under today’s rules. (Existing percentage-of-AGI caps—e.g., 60% for cash gifts to public charities—still apply.) 

 

Why it matters for 2025 tax planning 

If charitable giving is part of your regular routine, this is the year to be intentional. You can: 

  • Front-load future giving. Combine multiple years of donations into 2025 and take a larger deduction now. 
  • Use a donor-advised fund (DAF). Deduct your full contribution this year, then support charities from the fund over time. 
  • Donate appreciated investments. Avoid capital gains and receive a deduction for the full market value. 
  • Coordinate with IRA charitable distributions. Charitable deductions reduce taxable income, not AGI; Qualified Charitable Distributions (QCDs) from IRAs reduce AGI and can be powerful for SALT planning thresholds. QCD limit is $108,000 per person in 2025.  QCDs cannot go to donor-advised funds (DAFs). 

 

Case Study: Acting in 2025 vs. waiting until 2026 

Mark and Lisa have an annual income of $1 million and give about $25,000 to charity each year. 

  • If they wait until 2026, the new 0.5% rule means their first $5,000 of giving won’t count toward a deduction, leaving them with a $20,000 deductible amount each year. In addition, starting in 2026, the “2/37 rule” caps the value of their itemized deductions at ~35¢ per dollar if they’re in the 37% bracket. 
  • If they act in 2025 and contribute $75,000 to a donor-advised fund (covering three years of gifts), they can deduct the entire $75,000 under 2025’s more favorable rules. 

The result: 

  • 2026–2028 (wait): deductible amount each year ≈ $20,000; value ≈ $20,000 × 0.35 = $7,000/year → $21,000 in tax savings over 3 years. 
  • 2025 (accelerate): deductible amount $75,000 × 37% = $27,750 tax savings in 2025. 
  • Incremental after-tax benefit ≈ $27,750 − $21,000 = $6,750 (assuming 37% bracket in both periods). 

This preserves their giving pace while avoiding the 0.5% floor and the 2026 benefit cap. 

 

How can you use SALT deductions strategically in 2025 tax planning? 

For 2025, the SALT cap is $40,000 per tax return with 1% annual indexation thereafter through 2029. However, the full $40,000 cap phases down by 30% of Modified AGI above $500,000 (flooring at $10,000).  For many Massachusetts taxpayers, that creates room to deduct far more in state and local taxes—but only if you plan ahead. 

 

Case Study: Timing SALT payments to capture the 2025 benefit 

Alex and Jordan own two homes—a primary residence in Massachusetts and a vacation home in Maine. They pay about $18,000 in property taxes on the Massachusetts home and $10,000 on the Maine home each year, plus $12,000 in quarterly state income tax estimates. 

In 2025, they plan carefully (assuming $450,000 MAGI in 2025): 

  • Pay both property tax bills in full during the year ($28,000 total) 
  • Make all four 2025 state estimates on schedule 
  • Send their Q4-2025 estimate by December 31, 2025 (instead of waiting until the January 15, 2026 deadline) so it counts toward their 2025 return 

In 2025, they reach the full $40,000 deduction limit. If they wait until 2026, pushing that final state estimate into January, their deductible total would drop to about $28,000—leaving $12,000 of potential deductions unused.  If their 2025 MAGI were ≥ $600,000, the phase-down would drive their SALT cap down to the $10,000 floor—so timing alone wouldn’t help. 

The result: By simply adjusting timing, Alex and Jordan capture $12,000 in extra deductions without spending a dollar more.  

 

Can charitable giving and SALT strategies work together in 2025 tax planning? 

Absolutely. Both strategies depend on your AGI and overall financial picture, which means coordinating them can make your plan even more effective. 

For example, using a Qualified Charitable Donation (QCD) from your IRA 2025 will reduce your MAGI, potentially helping you qualify for more of the expanded 2025 SALT deduction. At the same time, the higher SALT cap may improve the benefit of itemizing versus using your standard deduction, so that might allow you to benefit from additional (non-QCD) charitable donations! 

Integrated planning—looking at giving, income, and state tax timing together—helps you keep more of what you earn while supporting the causes and communities you care about. 

 

What’s the Big Takeaway for 2025 Tax Planning? 

Tax planning in 2025 isn’t about complexity, it’s about timing your decisions before the rules change. 

  • Charitable gifts: 2025 is your final year for full deductions before the 0.5% floor begins (2026). 
  • Itemized benefit cap: From 2026, top-bracket taxpayers see itemized benefits limited to ~35¢ per dollar (the “2/37 rule”). 
  • SALT payments: The higher $40,000 cap creates a meaningful opening for itemizers who have less than $500,000 MAGI, but you need to act before December 31, 2025.

FAQs:

  1. Why is 2025 such an important year for tax planning?
    Because several major tax law changes take effect in 2026, 2025 is the last full year to take advantage of current deduction rules. Strategic 2025 tax planning—especially around charitable giving and SALT deductions—can help preserve valuable tax benefits before new limits apply.
  2. What’s the simplest charitable giving strategy for 2025?
    If you plan to give regularly over the next few years, consider front-loading your donations into 2025 through a donor-advised fund (DAF). You’ll secure a larger deduction this year, then decide when and where to give later.
  3. How do SALT deductions fit into my 2025 tax plan?
    The SALT deduction cap increases to $40,000 starting in 2025, which allows many taxpayers to deduct more property and state income taxes. Timing your payments—especially your final state tax estimate—before year-end 2025 can make a real difference.
  4. Should I coordinate my charitable and SALT strategies?
    Yes. SALT capacity uses Modified AGI, while charitable deductions reduce taxable income (except QCDs, which reduce AGI). Integrate these moves so you maximize itemized benefits without inadvertently tripping SALT phase-downs.
  5. What’s one thing I can do before year-end to get started?
    Reach out to your tax advisor to project your 2025 income and review your giving and payment schedules. A short conversation now can reveal opportunities that may not be available once 2026 begins.
