The 1040-SR tax table is the same tax table used with Form 1040: you take the taxable income shown on line 15 of your return, find the $50 range it falls into, and read across to the column for your filing status. The number at that intersection is your federal income tax. Form 1040-SR uses larger print and a built-in standard deduction chart for taxpayers 65 and older, but the rates and the lookup table are identical to the regular 1040.
How To Look Up Your Tax
Your taxable income appears on line 15 of Form 1040-SR, after you subtract your standard or itemized deduction from adjusted gross income.1Internal Revenue Service. Form 1040-SR U.S. Income Tax Return for Seniors That single number is what you carry into the table.
The tax table is published in IRS Publication 1040 and organized in $50 increments.2Internal Revenue Service. Publication 1040 – Tax and Earned Income Credit Tables Each row shows an “At least” amount and a “But less than” amount. Find the row your taxable income falls into, then move across to the column for your filing status: Single, Married Filing Jointly, Married Filing Separately, or Head of Household. The figure in that cell is your tax.
Two practical cautions. First, the filing-status columns sit close together on the printed page, and drifting one column over is the most common error. A straightedge or a folded piece of paper keeps your eye on the right row. Second, a taxable income that lands exactly on a boundary goes into the row where it appears in the “At least” column. Taxable income of $25,300 belongs in the “$25,300–$25,350” row, not the row below it.
If Your Taxable Income Is $100,000 or More
The tax table only runs up to $99,999. Above that, you use the Tax Computation Worksheet in the Form 1040 instructions, which applies the statutory bracket rates directly to your income.2Internal Revenue Service. Publication 1040 – Tax and Earned Income Credit Tables The worksheet produces the same result the brackets would; the table simply pre-computes it for lower income levels.
The Senior Standard Deduction That Sets Line 15
Because the standard deduction shrinks your taxable income before you touch the table, the senior amount is often the single biggest factor in what you end up owing. Federal law adds an extra amount on top of the base standard deduction for each filer who is 65 or older or blind.3Office of the Law Revision Counsel. 26 U.S.C. 63 – Taxable Income Defined
The base standard deductions for tax year 2026 are $16,100 for single filers or married filing separately, $32,200 for married filing jointly or a qualifying surviving spouse, and $24,150 for head of household.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
On top of the base, filers who are 65 or older add a supplemental amount. For the 2025 tax year returns most seniors are filing now, that additional amount is $2,000 if you are single or head of household, and $1,600 if you are married or a surviving spouse.5Internal Revenue Service. 2025 Instructions for Form 1040 If both spouses on a joint return are 65 or older, each spouse claims the additional amount. A single filer age 65 or older filing for 2025 gets $17,750 total, compared with $15,750 for a younger filer. A married couple where both are 65 or older gets $34,700.
The One Big Beautiful Bill also created a temporary enhanced deduction for seniors covering tax years 2025 through 2028, and the 2026 base figures from the IRS already incorporate some of those changes.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Check the instructions packaged with Form 1040-SR for your filing year to confirm the exact total. If itemizing produces a larger deduction than the standard amount, you can itemize on Form 1040-SR instead.
You qualify to use Form 1040-SR if you were born before January 2, 1962, meaning you turned 65 by the end of 2026. The IRS treats you as reaching age 65 on the day before your birthday.6Internal Revenue Service. Publication 554 – Tax Guide for Seniors On a joint return, only one spouse has to meet the age threshold.7Internal Revenue Service.

2026 Tax Brackets Behind the Table
Whether you use the table or the worksheet, the rates driving both are the same. The federal income tax has seven brackets, and the 2026 thresholds are:4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
- 10%: up to $12,400 single / $24,800 joint
- 12%: $12,401–$50,400 single / $24,801–$100,800 joint
- 22%: $50,401–$105,700 single / $100,801–$211,400 joint
- 24%: $105,701–$201,775 single / $211,401–$403,550 joint
- 32%: $201,776–$256,225 single / $403,551–$512,450 joint
- 35%: $256,226–$640,600 single / $512,451–$768,700 joint
- 37%: above $640,600 single / above $768,700 joint
The brackets are progressive. Only the income within each range is taxed at that range’s rate. A single filer with $60,000 of taxable income pays 10% on the first $12,400, 12% on the next slice, and 22% only on the portion above $50,400. The table bakes this arithmetic into a single number so you don’t have to run the calculation yourself.
Social Security Can Change the Number You Look Up
Before you get to line 15, part of your Social Security may become taxable income and raise the figure you carry into the table. Whether that happens depends on your “combined income,” which is adjusted gross income plus any tax-exempt interest plus half of your Social Security benefits. The thresholds have never been adjusted for inflation.8Office of the Law Revision Counsel. 26 U.S.C. 86 – Social Security and Tier 1 Railroad Retirement Benefits
- Single, head of household, or qualifying surviving spouse: combined income above $25,000 makes up to 50% of benefits taxable; above $34,000, up to 85% becomes taxable.
- Married filing jointly: above $32,000 triggers the 50% level; above $44,000, up to 85% becomes taxable.
- Married filing separately while living with a spouse: the base amount is $0, so benefits are taxable from the first dollar of combined income.
IRS Publication 915 has the worksheet that calculates the exact taxable portion.9Internal Revenue Service. Publication 915 – Social Security and Equivalent Railroad Retirement Benefits Required minimum distributions from traditional IRAs and most employer retirement plans, which generally begin at age 73, also flow into adjusted gross income and count toward combined income.10Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs) Pension income, IRA withdrawals, and investment gains all interact here, and this is where the taxable-income number that feeds the table actually gets built.
Credit for the Elderly or Disabled
After you read your tax from the table, one senior-specific credit can reduce it further. The Credit for the Elderly or Disabled is available to filers 65 or older, and to certain people under 65 who are permanently and totally disabled. It equals 15% of an initial base amount that depends on filing status:11Office of the Law Revision Counsel. 26 U.S.C. 22 – Credit for the Elderly and the Permanently and Totally Disabled
- Single or joint return with one qualifying spouse: $5,000
- Joint return with both spouses qualifying: $7,500
- Married filing separately: $3,750
The base gets reduced by nontaxable Social Security or pension benefits and by adjusted gross income above set thresholds before the 15% is applied. The phase-outs are low enough that many middle-income seniors won’t qualify, but if income comes mostly from Social Security, the credit can still deliver a benefit. You claim it on Schedule R attached to Form 1040-SR. The maximum is $1,125 (15% of $7,500) for a joint return where both spouses qualify, though the reductions usually bring the actual amount lower.
