Tax year 2026 · US federal estimate in USD · for common resident-taxpayer wage and sole-proprietor cases. This does not calculate state/local taxes or automatically calculate refundable credits.
1. Filing situation Tax year2026 income (return normally filed in 2027) Tax residencySelect your situation US citizen or US resident for tax purposes Nonresident or unsure — request tailored help Filing statusSingle Married filing jointly Married filing separately Head of household — eligibility confirmed Qualifying surviving spouse — eligibility confirmed
Nonresident, dependent and complex cases are directed to a tailored review rather than shown an unreliable figure. Supported annual income is up to $200,000 for single/head-of-household/surviving-spouse filers, $250,000 jointly and $125,000 separately.
2. Annual income before deductions Enter annual totals in USD, not monthly amounts. Wages use federal taxable wages (W-2 box 1), not take-home pay. Business profit means receipts minus business expenses, before personal deductions and SE tax.

Do not enter LLC distributions as profit without checking the tax classification. No partnership/S-corp K-1, business losses/carryovers or complex QBI limitations are modelled.
3. Deductions and age Other eligible above-the-line adjustments (e.g. deductible IRA/HSA) Eligible business-related health-insurance/retirement adjustments Eligible itemized-deduction total, after applicable limits Eligible cash charitable gifts if using standard deduction
Do not deduct the same amount twice. The tool selects the larger standard or entered itemized deduction, except when the married-separate spouse-itemizes rule applies. Non-itemizer cash-charity limits are $1,000, or $2,000 jointly.
4. Dependents and credits Qualifying children under 17 meeting all Child Tax Credit/SSN rules Other dependents eligible for the $500 non-refundable credit Other verified non-refundable federal income-tax credits Verified refundable-credit total (only if eligibility/amount is known)
The tool estimates the non-refundable $2,200 child credit and $500 other-dependent credit only. It does not work out EITC, refundable Additional Child Tax Credit, education or health-insurance credits. Enter independently verified refundable credits above if known; otherwise results are before those benefits.
5. Payments already made Federal income tax withheld (W-2 box 2 and other federal withholding) Federal estimated-tax payments for 2026
Do not include state withholding or employee Social Security/Medicare taxes in these payment boxes.
Method, limits and official sources Uses 2026 progressive federal rates, standard/age/blind deductions, the enhanced senior deduction where selected, basic eligible QBI, half-SE deduction and per-person Social Security wage limits. It uses annual rate schedules, so IRS tax-table rounding can differ. This is a planning tool, not a filed return or guaranteed refund. Entries are calculated in your browser and are not submitted or stored by this tool.
