## Default answer

Example with the default inputs (Filing status Single, You are 65 or older Yes, Modified AGI $50,000.00, Tax year 2,026): At $50,000.00 of modified AGI, the new senior deduction is $6,000.00 and saves $720.00 of federal tax.

## Inputs

| Key | Label | Description |
| --- | --- | --- |
| status | Filing status | Your federal filing status. Married people must file jointly to claim it. |
| you | You are 65 or older | Born before January 2, 1962, for tax year 2026 (one year earlier for each earlier tax year). |
| spouse | Your spouse is 65 or older | On a joint return, your spouse also gets the deduction if 65 or older. |
| magi | Modified AGI | Your adjusted gross income (Form 1040 line 11), plus any foreign income you excluded. Taxable Social Security counts. |
| year | Tax year | The deduction applies to tax years 2025 to 2028. |

## Outputs

| Key | Label | Description |
| --- | --- | --- |
| deduction | Senior deduction | The deduction on Schedule 1-A line 37, for everyone on the return. |
| each | Per person | $6,000 less the phase-out. |
| people | People who qualify | People on the return aged 65 or older. |
| phaseout | Phase-out per person | 6% of modified AGI over the threshold. |
| saved | Federal tax saved | Tax without the deduction minus tax with it, on the standard deduction, treating the income as ordinary. |
| ends | Deduction ends at modified AGI | Where the phase-out reaches 0. |
| reason | Note | Why the deduction is 0, or which rates the tax uses. |

## Method

Per person = $6,000 − 6% × (modified AGI − $75,000), or − $150,000 on a joint return, not below 0. Deduction = per person × people 65 or older on the return (both spouses on a joint return). Married filing separately gets none. Tax saved = Form 1040 tax without it − tax with it, both with the standard deduction and its $2,050 (single, head of household) or $1,650 (married) addition for each person 65 or older.

## Assumptions

- The deduction is for tax years 2025 to 2028 (P.L. 119-21 section 70103). It is taken whether you itemize or not.
- Each person 65 or older must have a Social Security number valid for work, and the return must include it.
- The tax saved treats your modified AGI as ordinary income with the standard deduction and no credits; years other than 2026 use the 2026 federal tax tables and say so.
- An estimate, not tax advice.

## Worked examples

1. status = single, you = yes, magi = $50,000.00 gives deduction = $6,000.00, saved = $720.00, ends = $175,000.00. Source: IRC 151(d)(5)(C) (P.L. 119-21 section 70103).
2. status = mfj, you = yes, spouse = yes, magi = $180,000.00 gives each = $4,200.00, deduction = $8,400.00, phaseout = $1,800.00, ends = $250,000.00.
3. status = single, you = yes, magi = $120,000.00 gives deduction = $3,300.00.
4. status = single, you = yes, magi = $200,000.00 gives deduction = $0.00, saved = $0.00.
5. status = mfs, you = yes, magi = $50,000.00 gives deduction = $0.00, people = 0.

## FAQ

### What is the new senior tax deduction?

A deduction of up to $6,000 for each person aged 65 or older, added by P.L. 119-21 (the 2025 tax law) for tax years 2025 to 2028. A married couple who are both 65 or older can deduct up to $12,000. It is on Schedule 1-A and is in addition to the regular standard deduction and its extra amount for age 65.

### Who qualifies?

You must be 65 or older at the end of the year (for 2026, born before January 2, 1962), have a Social Security number valid for work, and file jointly if you are married. Married people filing separately cannot claim it.

### What are the income limits?

The $6,000 falls by 6% of your modified AGI over $75,000, or over $150,000 on a joint return. It reaches 0 at $175,000 for a single filer and at $250,000 on a joint return.

### Do I need to itemize to get it?

No. You can take it with the standard deduction or with itemized deductions. It lowers taxable income, not AGI.

### Does it make Social Security tax-free?

Not directly. It is a deduction from income, so it lowers the tax on any income, taxable Social Security included. Many retirees with modest income then owe no federal tax on their benefits.

### How much tax does it save?

The deduction times your top tax rate, roughly. At 12%, $6,000 saves $720; at 22%, $1,320. If your taxable income is already 0, it saves nothing.
