## What this calculates

Find out how much of your income is actually subject to federal tax. Enter your gross income, adjustments, and filing status to see your taxable income after deductions. Uses 2025 standard deduction amounts.

## Inputs

- **Gross Income** ($) — min 0 — Total income from all sources (W-2 wages, 1099, etc.).
- **Above-the-Line Adjustments** ($) — min 0 — IRA contributions, student loan interest, HSA, etc.
- **Filing Status** — options: Single, Married Filing Jointly, Married Filing Separately, Head of Household — Your tax filing status determines the standard deduction.
- **Deduction Type** — options: Standard Deduction, Itemized Deductions — Choose whichever is higher to reduce your taxable income.
- **Itemized Deduction Amount** ($) — min 0 — Total itemized deductions (mortgage interest, SALT, charity, etc.).

## Outputs

- **Adjusted Gross Income (AGI)** — formatted as currency — Gross income minus above-the-line adjustments.
- **Deduction Amount** — formatted as currency — The standard or itemized deduction applied.
- **Taxable Income** — formatted as currency — AGI minus your deduction. This is the amount subject to federal income tax.

## Details

Your taxable income is the amount the IRS actually taxes, and it is usually much less than your gross income. The calculation follows three steps: start with gross income, subtract above-the-line adjustments to get your Adjusted Gross Income (AGI), then subtract either the standard deduction or your itemized deductions.

For 2025, the standard deduction is $15,000 for single filers, $30,000 for married filing jointly, $15,000 for married filing separately, and $22,500 for head of household. If your itemized deductions (mortgage interest, state and local taxes up to $10,000, charitable donations, medical expenses above 7.5% of AGI) exceed the standard deduction, itemizing saves you more.

For example, someone earning $85,000 filing single with no adjustments has an AGI of $85,000. After the $15,000 standard deduction, their taxable income is $70,000. That $70,000 is what flows through the tax brackets to determine how much federal income tax they owe.

## Frequently Asked Questions

**Q: What is the standard deduction for 2025?**

A: For the 2025 tax year, the standard deduction is $15,000 for single filers, $30,000 for married filing jointly, $15,000 for married filing separately, and $22,500 for head of household. Taxpayers age 65 or older get an additional $1,950 (single) or $1,550 (married) added to their standard deduction.

**Q: Should I take the standard deduction or itemize?**

A: Take whichever is larger. Since the 2017 Tax Cuts and Jobs Act nearly doubled the standard deduction, roughly 90% of taxpayers now take the standard deduction. Itemizing tends to make sense if you have a large mortgage, pay high state and local taxes (up to the $10,000 SALT cap), or make significant charitable contributions.

**Q: What are above-the-line adjustments?**

A: Above-the-line adjustments (also called adjustments to income) reduce your gross income to calculate AGI. Common ones include traditional IRA contributions, student loan interest (up to $2,500), HSA contributions, self-employment tax deduction, and educator expenses. You can claim these even if you take the standard deduction.

**Q: Is AGI the same as taxable income?**

A: No. Adjusted Gross Income (AGI) is your gross income minus above-the-line adjustments. Taxable income is your AGI minus the standard or itemized deduction. AGI is an important intermediate number because many tax credits and deduction phase-outs are based on it. Your actual tax bill is calculated from your taxable income.
