How to calculate taxable income
Calculating your taxable income is a fairly straightforward process.
Step 1: Gross income
Collect all your tax documents, like a W-2, 1099, or K-1. Add up the totals on each document to get your gross income.
Step 2: Adjusted gross income
Once you have your gross income, you adjust your income for certain items. These "above-the-line" deductions include retirement account contributions, student loan interest, healthcare expenses, or tuition expenses. Subtract their total from your gross income to get your adjusted gross income.
Step 3: Deductions
You can either take the standard deduction or itemize deductions.
Itemized deductions include property taxes, mortgage interest, state and local taxes or sales tax, charitable contributions, unreimbursed medical expenses, and gambling losses. If the total amount of deductible expenses is less than the standard deduction, simply use the standard deduction.
Step 4: Taxable income
Your taxable income is your adjusted gross income minus your deductions.
