AGI and Taxable Income Calculator

Estimate total income, adjusted gross income, and taxable income from common Form 1040 income components, above-the-line adjustments, and the supplied standard or itemized deduction.

Inputs

Federal income and filing inputs

Select the federal tax year for your worksheet. The formula structure is unchanged; tax-year-specific classification and deduction rules still require verification.

Range: 0–100,000,000 $

Enter wages, salary, and tips from your wage statements after using the amount applicable to this return.

Range: 0–100,000,000 $

Enter taxable interest and dividend income included in the return. Use a separate qualified-dividend or investment calculator when tax-rate treatment matters.

Range: -100,000,000–100,000,000 $

Enter the net capital gain or loss used on the return after the applicable transaction and carryover work. Negative values represent a net loss.

Range: -100,000,000–100,000,000 $

Enter the net amount already calculated from business, Schedule E, or rental records. Do not use gross receipts when expenses or passive-loss limits still need to be applied.

Range: 0–100,000,000 $

Enter the taxable portion of IRA, 401(k), pension, or annuity income after applying the relevant distribution worksheet.

Range: -100,000,000–100,000,000 $

Enter other taxable income or loss already classified for the return. Do not enter tax-exempt income; determine taxable Social Security or specialty income separately first.

Range: 0–100,000,000 $

Enter deductible adjustments already supported by the return worksheet, such as eligible HSA, IRA, student-loan-interest, or self-employed deductions. This field does not determine eligibility.

Range: 0–100,000,000 $

Enter the deduction selected for the return after comparing standard and itemized deductions. Use the separate deduction calculator when the choice still needs analysis.

Tax-year basis

How to interpret this result
This estimate shows how the entered income components sum to total income, how above-the-line adjustments produce AGI, and how the supplied standard or itemized deduction produces taxable income. Edit the component amounts to reconcile the estimate with your Form 1040 worksheet.
Applicability and limits
This is a federal planning estimate for the selected tax year. Enter net amounts that have already been classified for the return; the calculator does not decide whether income is taxable, whether a loss is deductible, whether Social Security benefits are taxable, or whether a deduction is allowed. It does not calculate tax brackets, credits, state tax, or the full Form 1040.
Calculation basis
Follows the IRS Form 1040 concept of total income, adjustments to income, adjusted gross income, deduction, and taxable income. The calculator adds the named income components, subtracts the supplied above-the-line adjustments, floors AGI at zero for this planning view, then subtracts the supplied standard or itemized deduction and floors taxable income at zero. Verify Form 1040 and Schedule 1 treatment for the selected year.

What to check

  • A taxpayer enters the amounts from a current planning worksheet to estimate a federal result before filing or changing a tax decision.
  • Use it when preparing, reviewing, or comparing a federal tax estimate.
  • This is a federal planning estimate for the selected tax year. Enter net amounts that have already been classified for the return; the calculator does not decide whether income is taxable, whether a loss is deductible, whether Social Security benefits are taxable, or whether a deduction is allowed. It does not calculate tax brackets, credits, state tax, or the full Form 1040.
