Taxable Income

Taxable Income — what it means, how it works, and a real example, explained without the jargon.

What is Taxable Income?

Taxable income is the slice of your income the tax brackets are actually applied to — what's left after you've taken your deductions. It's almost always lower than what you earned.

How it works

Take your AGI, subtract either the standard deduction or your itemized deductions, then subtract the QBI deduction if you run a qualifying business. The result is taxable income, and only that figure gets run through the 10%–37% brackets.

A quick example

A single filer with $73,000 of AGI who takes the $15,000 standard deduction has taxable income of $58,000 — that's the number the brackets tax, not the $73,000.

What people get wrong

Earning more never means your whole income jumps a bracket. Only the dollars above each threshold are taxed at the higher rate — see the tax brackets page for the full picture.
