The IRS has quietly raised the standard deduction for the 2025 tax year, and if you've been filing the same way for years without checking the numbers, you may be leaving real money on the table.
For single filers, the standard deduction is now $15,000, up $400 from last year.
Married couples filing jointly get $30,000, a $800 bump.
These increases come courtesy of inflation adjustments the IRS makes most years, and they matter more than most people realize.
A bigger standard deduction means less of your income gets taxed, which can translate to a smaller bill or a larger refund when you file in early 2026.
But here's the catch: roughly 90% of taxpayers take the standard deduction, according to IRS data, which means most people never bother comparing it to itemizing.
If you paid a lot in mortgage interest, gave generously to charity, or live in a state with high income or property taxes, itemizing could still beat the standard deduction—especially now that the SALT cap has been raised to $40,000 for many filers under recent tax law changes.
There's also a lesser-known bonus: if you're 65 or older, or blind, you can tack on an additional standard deduction.
For 2025, that extra amount is $1,600 for single filers and $1,300 per qualifying person for married couples.
It's not huge, but it's free money for people who qualify and often goes unclaimed.
One more wrinkle worth knowing: the standard deduction can change how much you owe if you have side income, gig work, or investments.
A bigger deduction doesn't erase self-employment taxes or capital gains taxes, but it can pull more of your regular income into the zero-tax bracket.
Before you file, take ten minutes to add up your potential itemized deductions—mortgage interest, charitable giving, medical expenses above the threshold, state and local taxes.
If that total comes anywhere close to your standard deduction, it's worth running both scenarios through tax software.
Most programs do this automatically, but only if you enter the underlying numbers.
If you're married, divorced, widowed, or your income changed significantly this year, your filing status may have shifted too—and that changes your standard deduction entirely.
Final Thoughts
A quick check now beats a surprise later. **The bottom line:** The rising standard deduction is good news for most filers, but "most" isn't "everyone." Spending a few minutes to confirm you're actually getting the bigger write-off is one of the easiest money moves in personal finance.
