Cheat Sheet: Key Tax Changes for Tax Year 2025
You can include this section in your email under the "What’s New for 2025" header.
1. New "Personal" Car Loan Interest Deduction
The Change: For the first time in years, you may be able to deduct interest on a personal vehicle.
The Rules:
Applies to NEW car loans originated after Dec 31, 2024.
Limit: You can deduct up to $10,000 of interest.
Phase-out: This deduction begins to phase out if your Modified Adjusted Gross Income (MAGI) exceeds $100,000 (Single) or $200,000 (Married Filing Jointly).
Note for Business Owners: This is separate from the standard business vehicle interest deduction, which remains fully deductible for the business-use percentage of the vehicle.
2. SALT Cap Increase (State & Local Tax)
The Change: The "SALT Cap" (which limits how much property and state income tax you can write off) has increased significantly.
New Limit: $40,000 (up from the previous $10,000 cap).
Impact: If you own a home in a high-property-tax area or pay significant state income taxes, itemizing your deductions might now be better than taking the Standard Deduction.
3. Standard Deduction (Inflation Adjusted)
If you do not itemize, the new standard deduction amounts for 2025 are:
Married Filing Jointly: ~$31,500
Single / Married Filing Separately: ~$15,750
Head of Household: ~$23,625
4. Tax Brackets & Rates (2025 Tax Year)
Income thresholds have shifted up due to inflation. Here is where the breaks generally fall for Married Filing Jointly:
10%: Income up to ~$23,850
12%: Income up to ~$96,950
22%: Income up to ~$206,700
24%: Income up to ~$395,100
32%: Income up to ~$501,600
35%: Income up to ~$751,600
37%: Income above ~$751,600
5. Business Vehicle Depreciation (Bonus Depreciation)
The Change: While Bonus Depreciation was scheduled to phase down to 40%, new provisions have reinstated 100% Bonus Depreciation for qualifying business vehicles purchased and placed in service after January 19, 2025.
Impact: If you bought a heavy SUV (over 6,000 lbs GVWR) for your business last year, we can likely write off the entire cost in one year again.
