How It Works
Federal income tax is never applied to your whole paycheck. It applies to a narrower figure called taxable income, and pinning that number down is what separates a reliable estimate of your 2026 tax bill from a guess. Walking through the figure step by step also shows exactly how each deduction or adjustment moves your final liability up or down.
To arrive at the number, start with gross income, subtract any above-the-line adjustments, and then subtract either the standard deduction or your itemized deductions, whichever is larger. The standard deduction for 2026 is $16,100 for a single filer and $32,200 for married couples filing jointly. Put simply: Gross Income - Adjustments to Income - (Standard Deduction OR Itemized Deductions) = Taxable Income.
Two categories of subtraction often get confused. Above-the-line adjustments, such as IRA contributions or student loan interest, come off before the deduction choice; below-the-line deductions are the standard or itemized amount itself. Filers who overlook eligible adjustments or skip deductions they qualify for end up reporting more income than they should and paying more than necessary, so detailed records for every claimed item are worth maintaining year-round.
Example: Single Filer with Student Loan Interest and Itemized Deductions
- 1 Sarah, a single filer, has a gross income of $75,000 in 2026. She paid $2,500 in student loan interest and has itemized deductions totaling $18,000 (including mortgage interest and state income taxes).
- 2 First, subtract adjustments from gross income: $75,000 (Gross Income) - $2,500 (Student Loan Interest Adjustment) = $72,500 (Adjusted Gross Income). Next, compare her itemized deductions ($18,000) to the 2026 standard deduction for a single filer ($16,100). Since her itemized deductions are higher, she will use those. Finally, subtract the deductions from her AGI: $72,500 (AGI) - $18,000 (Itemized Deductions) = $54,500.
- 3 Sarah's taxable income for 2026 is $54,500.
- 4 This $54,500 is the amount of income that will be subject to the federal income tax brackets for single filers in 2026. This calculation helps Sarah understand how much of her income is actually taxed, after accounting for her eligible reductions.
