The IRS standard deduction for the 2025 tax year sits at $15,000 for single filers and $30,000 for married couples filing jointly, per figures the agency released in the fall.
That's up roughly $400 and $800, respectively, from the prior year — an adjustment tied to inflation, not a new giveaway from Congress.
Here's the part that gets buried in the headlines: the standard deduction has been climbing for years, yet it hasn't kept pace with the actual cost of getting by.
Rent, groceries, insurance, and childcare have all outrun it in most metro areas.
A bigger number on a tax form feels like a raise until you check what it buys.
The mechanics matter more than the marketing.
The standard deduction is simply the amount of income you can shield from federal tax without itemizing.
If you're single and earn $60,000, you're taxed on roughly $45,000 — not $60,000.
But the alternative, itemizing, only wins if your mortgage interest, state and local taxes, charitable giving, and medical expenses add up to more than the standard amount.
The 2017 tax law roughly doubled the standard deduction while capping the state and local tax deduction at $10,000.
The result: millions of filers who used to itemize now take the standard route, which means they get no extra benefit from mortgage interest or charitable donations.
If you own a home in a high-tax state, you likely lost ground even as your "deduction" grew.
The standard deduction includes an extra amount for those 65 and older — $2,000 for singles, $1,600 per spouse for joint filers in 2025 — but Social Security taxation thresholds have never been adjusted for inflation since they were set in the 1980s and 1990s.
More of your benefit becomes taxable over time, and a slightly larger deduction doesn't fix that.
The 2017 law's individual provisions are set to expire at the end of 2025 unless Congress acts.
If they lapse, the standard deduction shrinks back toward pre-2018 levels, the SALT cap disappears, and the whole calculus flips.
Both parties say they want to prevent that.
Anyone planning a 2026 budget around today's numbers is building on sand.
The practical takeaway: don't assume the standard deduction is automatically your best move.
Run the numbers both ways, especially if you donated significantly, paid large medical bills, or have a mortgage originated before rates spiked.
Our take: the annual standard deduction increase is framed as relief, but it's mostly an inflation patch on a system that quietly shifted who benefits.
The people cheering loudest — tax preparers and software companies — profit either way, while the filers who lost itemized write-offs got a round of applause instead of a refund.
Final Thoughts
Watch Congress this year, because that's where your 2026 tax bill is actually being decided.
