## 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).

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

### Who is a qualifying child?

A son, daughter, stepchild, foster child, sibling or their descendant who is under 17 at the end of the year, lived with you more than half the year, has a Social Security number and did not provide over half of their own support. At least one parent claiming the credit needs a Social Security number too.

### What if I owe no tax?

Up to $1,700 per child is paid as the additional child tax credit: 15% of earned income above $2,500.

### What about older children?

Dependents 17 and older, and other relatives you support, give the $500 credit for other dependents.

### 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.
