The OBBBA Senior Deduction is claimed on the new IRS Schedule 1-A when filing your 2026 Form 1040. Your tax software will automatically populate this if you indicate you are age 65+. If filing manually, enter your qualifying deduction amount on Schedule 1-A and carry it to Line 12c of Form 1040.

Frequently Asked Questions โ€” 2026 Senior Tax Deduction

Under Section 70103 of the One Big Beautiful Bill (Public Law 119-21), Americans aged 65 or older are entitled to a new $6,000 'bonus deduction' on top of the standard deduction and the existing additional standard deduction for seniors. For a single filer aged 65+, this means you can earn up to approximately $24,150 before paying any federal income tax โ€” effectively eliminating federal taxes on Social Security for millions of middle-income retirees.
In 2026, eligible seniors benefit from three stacked deductions: (1) The standard 2026 deduction of $16,100 (single) or $32,200 (married), (2) The existing additional standard deduction for age 65+ of $2,050 (single) or $3,300 (married), and (3) The new OBBBA Senior Deduction of $6,000 (single) or $12,000 (married). Combined, a single senior can shelter $24,150 of income tax-free, while a married couple can shelter $47,500.
The full $6,000 deduction is available for single filers with MAGI under $75,000 and married filers under $150,000. The deduction gradually phases out above these thresholds, fully disappearing at approximately $175,000 (single) or $250,000 (married). Middle-income retirees who rely on Social Security plus modest pension or investment income will typically qualify for the full deduction.
For many retirees, yes โ€” effectively. Because the combined deductions (standard + additional + OBBBA senior) can shelter $24,150+ of income, seniors whose total income (including the taxable portion of Social Security) falls below this threshold will owe $0 in federal income tax. However, Social Security itself is still subject to federal taxation under the existing combined income formula โ€” the OBBBA senior deduction offsets rather than directly exempts Social Security income.
You claim the OBBBA Senior Deduction on IRS Schedule 1-A when filing your 2026 Form 1040. You must be age 65 or older by December 31, 2026. The IRS will include this deduction on the standard tax return โ€” it is not a special form or credit, just an additional line item on Schedule 1-A. Your tax software will apply it automatically for tax year 2026 returns.
No โ€” they are separate. The additional standard deduction for seniors has existed for years and is $2,050 (single) or $3,300 (married) in 2026. The new OBBBA Section 70103 deduction is a separate, larger $6,000 (single) / $12,000 (married) deduction created specifically by the One Big Beautiful Bill. Both apply simultaneously, which is why we call it the 'Triple Stack.'
Yes. If you have earned income from wages (working past 65), Social Security (6.2%) and Medicare (1.45%) still apply to those wages โ€” there is no age-based FICA exemption. The OBBBA Senior Deduction only reduces your federal income tax liability, not FICA taxes. However, the dramatically higher deduction threshold means more of your combined retirement and earned income is shielded from income tax.
Yes. If you are 65 or older and still working โ€” whether full-time, part-time, or collecting a pension while working โ€” you can claim the OBBBA Senior Deduction as long as your MAGI falls within the income limits ($75,000 single, $150,000 married for the full amount). The deduction applies to your total taxable income regardless of income source.
