## How your return is calculated

1. **Total income (line 9).** Wages, interest, dividends, IRA and pension income, the taxable part of Social Security, capital gains (losses limited to $3,000) and Schedule 1 income such as self-employment profit and unemployment.
2. **Adjusted gross income (line 11).** Total income minus half of self-employment tax, self-employed health insurance, HSA and deductible IRA contributions, educator expenses and student loan interest (up to $2,500).
3. **Deductions (lines 12–14).** The larger of the standard deduction ($16,100 single, $32,200 joint, $24,150 head of household, plus $2,050 or $1,650 for age 65 or blindness) or your itemized deductions; then the qualified business income deduction and Schedule 1-A deductions for tips, overtime, car loan interest and seniors.
4. **Tax (line 16).** From the IRS Tax Table below $100,000 of taxable income and the brackets above it. Qualified dividends and long-term gains go through the capital gain worksheet at 0%, 15% or 20%. Alternative minimum tax is added if it is higher.
5. **Credits (lines 19–21).** Child and dependent care, education and saver’s credits, then the Child Tax Credit of $2,200 per child and $500 per other dependent, each limited to the tax.
6. **Other taxes (line 23).** Self-employment tax, the 0.9% Additional Medicare tax and the 3.8% net investment income tax.
7. **Payments (lines 25–33).** Withholding, estimated payments and the refundable credits: earned income credit, additional child tax credit (up to $1,700 per child) and 40% of the American opportunity credit.
8. **Refund or amount owed (lines 34–37).** Payments minus total tax.

## Questions people ask

### How much of my Social Security is taxable?

None if your other income plus half your benefits is below $25,000 (single) or $32,000 (joint); up to 50% between that and $34,000 / $44,000; up to 85% above.

### Do states tax Social Security?

Most do not. Pick your state on the tax return calculator to see.

### Can I have tax withheld from benefits?

Yes, with Form W-4V at 7%, 10%, 12% or 22%.

### Is this the same as what tax software calculates?

It follows the same Form 1040 lines and IRS worksheets (Tax Table, qualified dividends and capital gain worksheet, Social Security benefits worksheet, Schedule 8812, EIC table). It does not cover every situation: foreign income, rental property, business assets, the premium tax credit and some credits are not included, and the QBI deduction assumes a business without employees.

### Which tax year should I pick?

Pick 2026 for the return you file in early 2027, or to check now whether your withholding is on track. Pick 2025 to check a return for last year, for example if you filed for an extension or want to amend.
