The clock is ticking on several significant tax changes that could impact your 2025 return—and your long-term financial strategy. With new provisions from the One Big Beautiful Bill Act (OBBBA) taking effect and key deadlines approaching, now is the time to understand what’s changing and how to make the most of these opportunities.
In this article, Domain Money outlines tax changes taking effect in 2026.
The Big Changes You Need to Know
The OBBBA, signed into law on July 4, 2025, introduced a mix of permanent extensions from the 2017 Tax Cuts and Jobs Act alongside new temporary provisions that could significantly impact your tax bill. Here’s what matters most:
New Deductions for 2025 (Retroactive for This Year’s Return)
The Senior Deduction: If you’re 65 or older, you may qualify for an additional deduction of up to $6,000 ($12,000 for married couples filing jointly). This phases out based on your modified adjusted gross income (MAGI)—starting at $75,000 for individuals and $150,000 for joint filers. The deduction amount is reduced by 6 cents for every $1 your MAGI is over the starting threshold.
Enhanced Child Tax Credit: Families will see a modest boost, with the Child Tax Credit increasing from $2,000 to $2,200 per qualifying child for 2025.
Auto Loan Interest Deduction: Purchased a new American-assembled vehicle in 2025? You might be able to deduct up to $10,000 in interest paid on your loan. The vehicle must weigh less than 14,000 pounds and have its final assembly in the U.S., and it must be for personal use. This deduction phases out for individuals with MAGI over $100,000 ($200,000 for joint filers).
No Tax on Tips and Overtime: Service workers can now deduct up to $25,000 in tip income, while overtime workers can deduct up to $12,500 ($25,000 for joint filers). Both come with income-based phaseouts starting at $150,000 MAGI ($300,000 for joint filers).
Energy Credits Sunset: If you’ve been considering clean energy improvements or an electric vehicle purchase, act quickly. Clean vehicle credits end for vehicles acquired after Sept. 30, 2025, while residential energy credits for solar panels, heat pumps, and other improvements expire for property placed into service after Dec. 31, 2025.
The SALT Cap Gets a Major Boost
For years, the $10,000 cap on state and local tax (SALT) deductions has been a pain point for taxpayers in high-tax states. Starting with your 2025 return, that cap jumps to $40,000 for single filers and married couples filing jointly. The limit will increase by 1% annually through 2029 before reverting to $10,000 in 2030.
However, there’s a caveat: The higher cap phases out for those with MAGI over $500,000 (or $250,000 for married filing separately), reducing by 30 cents for every dollar over that threshold.
Standard Deduction Increases
The standard deduction gets an extra 5% bump on top of inflation adjustments for 2025. For married couples filing jointly, t
