The $15,000 figure is the standard deduction that was originally announced for single filers for tax year 2025. Congress raised it to $15,750 for 2025 through the One, Big, Beautiful Bill Act, and for 2026 it climbs again to $16,100.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One, Big, Beautiful Bill It is a flat dollar amount you subtract from your income before your tax is calculated, and you claim it without receipts or documentation.
What the Standard Deduction Is
The standard deduction is the IRS’s built-in subtraction from your income. You don’t track expenses, keep receipts, or fill out an extra schedule to use it. You pick the amount that matches your filing status and enter it on your return. Most filers take this route because their individual deductible expenses don’t add up to more than the flat amount.
The $15,000 number entered public conversation as the initially published 2025 figure for single filers before Congress bumped it up. If you file your 2025 return, the single-filer amount is $15,750. If you’re looking ahead to a 2026 return, it’s $16,100. The number is set by federal law and adjusted each year for inflation.
2026 Amounts by Filing Status
- Single: $16,100
- Married filing jointly: $32,200
- Head of household: $24,150
- Married filing separately: $16,100
Joint filers get exactly double the single amount, so the standard deduction itself carries no marriage penalty.
Extra Amount if You’re 65 or Older or Blind
If you’re 65 or older, blind, or both, an additional amount stacks on top of your standard deduction for 2026:
- Single or head of household: $2,050 if you’re 65 or older, and another $2,050 if you’re blind.
- Married filing jointly or separately: $1,650 per qualifying spouse for age, and another $1,650 per qualifying spouse for blindness.
A single filer who is 65 or older gets $18,150 total ($16,100 plus $2,050). A married couple filing jointly where both spouses are over 65 gets $35,500 ($32,200 plus $3,300). These additions sit in the same section of the tax code as the basic standard deduction.2Office of the Law Revision Counsel. 26 USC 63 – Taxable Income Defined
Who Can’t Take It
A few groups are shut out of the standard deduction entirely:
- If you file as married filing separately and your spouse itemizes, your standard deduction is zero. You have to itemize too.
- Nonresident aliens generally can’t claim it.3Internal Revenue Service. Nonresident – Figuring Your Tax
- If you filed a short tax year because you changed your accounting period, no standard deduction is available.
If someone else can claim you as a dependent, your standard deduction is capped at the greater of a small base amount or your earned income plus a small additional amount, both adjusted for inflation.2Office of the Law Revision Counsel. 26 USC 63 – Taxable Income Defined A teenager earning $5,000 at a summer job gets a standard deduction roughly equal to that earned income, not the full $16,100.
How Much It Actually Saves You
A deduction doesn’t cut your tax bill dollar for dollar. It lowers your taxable income, and your savings equal the deduction times your marginal tax rate. In the 22% bracket, every $1,000 of deduction saves $220 in federal tax. In the 12% bracket, the same $1,000 saves $120.
For a single filer in the 22% bracket, the $16,100 standard deduction works out to roughly $3,542 in federal income tax saved. That’s real money, but it is not a $16,100 reduction in what you owe. This is where people often mix up deductions with credits. A $1,000 credit cuts your tax bill by $1,000 flat. A $1,000 deduction saves you somewhere between $100 and $370 depending on your bracket.
The 2026 federal income tax rates run from 10% on the first $12,400 of taxable income for a single filer up to 37% on income above $640,600.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One, Big, Beautiful Bill Because the system is progressive, the deduction peels income off the top of your stack, so it saves you money at your highest rate.
When Itemizing Beats the Standard Amount
Itemizing means listing your actual deductible expenses on Schedule A instead of using the flat amount. It only pays off when your qualifying expenses top the standard deduction. For a single filer in 2026, that means getting past $16,100. The categories that usually push people over the line:
State and Local Taxes
The deduction for state and local taxes (SALT) covers state income or sales taxes plus property taxes. Under the One, Big, Beautiful Bill, the cap rose to $40,000 for most filers ($20,000 if married filing separately), up from the $10,000 cap that applied from 2018 through 2024.4Internal Revenue Service. Topic No. 503, Deductible Taxes The higher cap phases down for taxpayers with modified adjusted gross income above $500,000 and eventually drops back to $10,000 for the highest earners. In a high-tax state, this one change can push your itemized total past the standard deduction by itself.
Mortgage Interest
Interest on a loan used to buy, build, or substantially improve your primary or second home is deductible when you itemize. The eligible loan balance is capped at $750,000 ($375,000 if married filing separately) for mortgages taken out after December 15, 2017. Your lender sends Form 1098 showing the interest you paid.5Internal Revenue Service. About Form 1098, Mortgage Interest Statement In the early years of a mortgage, when payments are mostly interest, this single line can be worth $10,000 or more.
Medical Expenses
Unreimbursed medical and dental costs are deductible only to the extent they exceed 7.5% of your adjusted gross income.6Office of the Law Revision Counsel. 26 U.S. Code 213 – Medical, Dental, Etc., Expenses If your AGI is $80,000, the first $6,000 of medical spending produces no deduction at all. Only the amount above that floor counts, which makes this one useful mostly in years with surgery, major dental work, or ongoing treatment for a chronic condition.
Charitable Contributions
Cash and property given to qualified charities are deductible when you itemize.7Office of the Law Revision Counsel. 26 U.S. Code 170 – Charitable, Etc., Contributions and Gifts Cash donations are generally limited to 60% of your AGI. Any single contribution of $250 or more requires a written acknowledgment from the charity before you file.
New Deductions That Stack on Top
The One, Big, Beautiful Bill Act created three new deductions for tax years 2025 through 2028 that work on top of the standard deduction. You don’t have to itemize to use them.8Internal Revenue Service. One, Big, Beautiful Bill Act – Tax Deductions for Working Americans and Seniors
Tips
If you work in an occupation that customarily received tips before 2025, you can deduct up to $25,000 per year in tip income reported on your W-2 or 1099. A tip jar added to a business that never had one won’t qualify. You need a Social Security number.
Overtime Premium
Employees paid overtime required under the Fair Labor Standards Act can deduct the premium portion of that pay. If you earn time-and-a-half, the deductible amount is the extra “half” above your regular rate. The cap is $12,500 per year ($25,000 for joint filers), and the deduction phases out above $150,000 of modified AGI ($300,000 joint).
Auto Loan Interest
Interest on a loan used to buy a vehicle for personal use is deductible up to $10,000 per year. Lease payments don’t count. The vehicle has to meet eligibility requirements, and the deduction runs through 2028.
How to Claim It
Whether you take the standard deduction or itemize, the amount goes on Line 12 of Form 1040. For the standard deduction, enter the figure that matches your filing status. If you itemize, you complete Schedule A first, totaling your SALT, mortgage interest, charitable gifts, and medical expenses, and the total transfers to Line 12.9Internal Revenue Service. Instructions for Schedule A (Form 1040) Your W-2 shows wages and tax already withheld,10Internal Revenue Service. About Form W-2, Wage and Tax Statement and homeowners who itemize mortgage interest will need Form 1098 from their lender.
The IRS offers free e-filing for taxpayers with AGI of $89,000 or less, with direct-deposit refunds generally arriving within 21 days.11Internal Revenue Service.

An extension buys you time to file, not time to pay; any tax owed is still due by the original deadline to avoid interest and late-payment penalties.
