The tax landscape shifted significantly in 2026 — most of the changes stem from the One Big Beautiful Bill, and several of them are specifically designed to benefit pre-retirees and retirees. Here's what changed, how much it matters, and what you should do about it.
The standard deduction in 2026:
That's up $700 (single) and $350 (joint) from 2025. Combined with the Senior Bonus Deduction below, the effective standard deduction for a married couple over 65 can reach $44,200.
Filers 65 and older receive an extra $6,000 deduction per person on top of the standard deduction. For a married couple where both spouses are 65+, that's $12,000 in additional tax relief — no itemizing required.
Easy to miss: This phases out by 6 cents for every dollar above $75,000 (single) / $150,000 (married). At $85,000 single, you'd receive $5,400 instead of $6,000.
The State and Local Tax deduction cap — previously $10,000 since 2024 — rises to $40,400 in 2026. This primarily benefits high-income earners in high-tax states like California, New York, New Jersey, and Minnesota.
The cap phases back down above $505,000 in income.
New in 2026: you can deduct interest on car loans for new U.S.-assembled vehicles, up to $10,000. This is an above-the-line deduction, available even if you take the standard deduction.
Phases out above $100,000 (single) / $200,000 (married) MAGI.
For 401(k) participants between ages 60 and 63, the catch-up contribution limit jumps to $11,250 — compared to the standard $8,000 catch-up for those 50 and older. Combined with the regular $23,500 limit, the total 401(k) ceiling for this age group is $34,750.
This is a four-year window to accelerate tax-deferred retirement savings before RMDs and distributions begin.
If your prior-year FICA wages exceeded $150,000, all catch-up contributions must now go to a Roth account rather than pre-tax. This means the tax benefit is deferred — you contribute after-tax dollars now, but withdrawals in retirement are tax-free.
For high earners, this changes the cash flow math on catch-up contributions. Plan accordingly.
Two new above-the-line deductions arrive in 2026:
These are claimed on your 2026 return, which you file in 2027.
Even if you take the standard deduction, you can now deduct up to:
This is new for 2026 tax year returns (filed in 2027). Note: if you're already using Qualified Charitable Distributions from your IRA, the QCD route typically delivers a larger tax benefit.
Several of these provisions are set to expire or phase down by 2029. That makes 2026 through 2028 a particularly important planning window — especially for Roth conversions, tax-loss harvesting, and large charitable gifts.
Each of these eight changes has a ripple effect on your overall tax picture — and the interactions between them matter as much as the individual rules. The Senior Bonus Deduction phases out. The SALT cap helps some but not others. The super catch-up window is only four years wide.
