Standard Deduction for Seniors — 2025 & 2026 Calculator
Calculate the IRS additional standard deduction for taxpayers age 65+, including the new 2025 OBBB $6,000 senior deduction stacked on top of existing benefits
The point to understand about the OBBB senior deduction: the new $6,000 is IN ADDITION TO your existing extra standard deduction for age 65+. If you're 65+ and single, that can mean $8,000+ more in total deductions than a younger taxpayer.

How much is the new senior tax deduction for 2025?
Under the One Big Beautiful Bill Act (OBBB), taxpayers age 65 and older receive a NEW $6,000 deduction ($12,000 for married couples where both are 65+) for tax years 2025-2028. This is IN ADDITION TO the existing additional standard deduction for seniors.
- NEW OBBB deduction: $6,000 per person age 65+ (not replacing existing benefits)
- Married couples where both are 65+: $12,000 OBBB deduction
- Existing additional standard deduction ($2,000 single or head of household / $1,600 per married spouse for 2025; $2,050 / $1,650 for 2026) still applies
- Phase-out begins above $75,000 modified AGI (single) or $150,000 (married filing jointly)

The OBBB senior deduction is a meaningful boost for retirees on Social Security and modest pensions — but the income phaseout means upper-middle-class retirees get nothing. The interaction with the existing 'additional standard deduction for 65+' confuses almost everyone.
Real-world scenario
Retired couple, both 68, $85K combined income
MFJ standard deduction 2025: $31,500. Plus the 65+ additional: $1,600 × 2 = $3,200. Plus the OBBB senior bonus: up to $6,000 × 2 = $12,000 (subject to MAGI phaseout starting $150K MFJ). Total deduction stack: $46,700. On $85K AGI, taxable income drops to ~$38K — keeping them comfortably in the 12% bracket.
The part most people miss
Provisional income is the silent tax. Up to 85% of your Social Security becomes taxable once half your SS plus other income (including tax-exempt interest, plus the excluded income and student loan interest deduction that IRS Pub 915 adds back) crosses $34K (single) / $44K (MFJ). The OBBB deduction doesn't reduce provisional income — meaning a Roth conversion or a big IRA withdrawal can trigger SS taxation that the new deduction doesn't shield against.

65+? You're getting TWO extra deductions in 2025.
The OBBB Act added a brand new $6,000 deduction for seniors ON TOP OF the existing additional standard deduction. For a married couple who are both 65+, the new law alone cuts federal income tax by up to $2,640 (at $150,000 of modified AGI; less at lower incomes, where more of the $12,000 falls in the 10% and 12% brackets).
Your Information
2025 base standard deduction + age-65 bonus ($2,000 single / $1,600 MFJ per spouse) + OBBB $6,000 senior add-on.
Schedule 1-A modified AGI = AGI plus any amounts excluded under IRC §911 (foreign earned income), §931, or §933. If none apply, your AGI is your MAGI.
Additional circumstances:
The $6,000 senior deduction requires an SSN valid for employment for each individual claiming it, and married taxpayers must file jointly.
