Frequently Asked Questions
What is the standard deduction for 2025?
For 2025, the standard deduction is $15,000 for single filers and married filing separately, $30,000 for married filing jointly, and $22,500 for head of household.
Should I take the standard deduction or itemize?
Take whichever is larger. Most taxpayers benefit from the standard deduction. Itemizing makes sense if your mortgage interest, state taxes, charitable contributions, and other deductible expenses exceed the standard deduction.
What counts as additional adjustments?
Common above-the-line adjustments include contributions to a traditional IRA, student loan interest (up to $2,500), self-employed health insurance premiums, and HSA contributions.
Does this calculator include FICA taxes?
This calculator focuses on federal income tax only. Social Security (6.2%) and Medicare (1.45%) taxes are calculated separately in the Paycheck Calculator.
What is the difference between gross income and taxable income?
Gross income is your total earnings before any deductions. Taxable income is gross income minus above-the-line adjustments minus your standard or itemized deduction. Federal income tax is calculated on taxable income.
How to Use This Calculator
Enter your gross income, select your filing status, and choose between the standard deduction or enter your itemized deductions. Optionally add above-the-line adjustments like IRA contributions.
Formula
Adjusted Gross Income (AGI) = Gross Income β Adjustments
Taxable Income = AGI β Deduction (Standard or Itemized)
Federal Tax = Sum of (income_in_bracket Γ rate) per bracket
Effective Rate = Federal Tax / Gross Income Γ 100
Taxable Income = AGI β Deduction (Standard or Itemized)
Federal Tax = Sum of (income_in_bracket Γ rate) per bracket
Effective Rate = Federal Tax / Gross Income Γ 100
Example
Single filer, $80,000 gross, standard deduction:
AGI: $80,000 | Taxable Income: $80,000 β $15,000 = $65,000
10% on $11,925 = $1,193 | 12% on $36,550 = $4,386 | 22% on $16,525 = $3,636
Total Tax: $9,215 | Effective: 11.5% | After-Tax: $70,785
AGI: $80,000 | Taxable Income: $80,000 β $15,000 = $65,000
10% on $11,925 = $1,193 | 12% on $36,550 = $4,386 | 22% on $16,525 = $3,636
Total Tax: $9,215 | Effective: 11.5% | After-Tax: $70,785
