How to Use This Calculator
Start with AGI, earned income, and federal tax before credits. If you do not know the pre-credit tax amount, use the Federal Income Tax Calculator first, then come back here to layer in credits.
Enter family, work, education, retirement, and adoption details. The result separates potential credit value, nonrefundable credits actually used against tax, refundable credits, and estimated refund or amount due after withholding.
Step 1: Start with AGI and earned income
Enter adjusted gross income or a close MAGI proxy, then enter earned income for EITC and ACTC estimates.
Step 2: Enter tax before credits
Use federal tax after deductions and brackets but before credits so nonrefundable credits can be capped correctly.
Step 3: Add family and work details
Enter qualifying children, other dependents, EITC child count, investment income, care expenses, and care qualifying persons.
Step 4: Add education, savings, and adoption details
Enter AOTC students and expenses, Lifetime Learning expenses, retirement savings contributions, adoption expenses, and manual credit entries.
Step 5: Review used vs refundable credits
Check which credits reduce tax, which remain unused, and which refundable credits increase estimated refund.
How the Tax Credit Estimate Works
The calculator starts with federal tax before credits. Nonrefundable credits reduce that tax, but not below zero. Refundable credits are added to withholding and payments, so they can create or increase a refund after tax is reduced.
| Credit | 2026 planning rule | Income limit or phaseout | Refundable? |
|---|---|---|---|
| Child Tax Credit | $2,200 per qualifying child under age 17, with up to $1,700 per child treated as potentially refundable through ACTC. | $400,000 MFJ; $200,000 other filers | Partly refundable through ACTC |
| Earned Income Credit | 2026 EITC maximums are $664 with no qualifying child, $4,427 with one, $7,316 with two, and $8,231 with three or more qualifying children. | Depends on filing status and qualifying-child count | Refundable |
| Child and Dependent Care Credit | Child and dependent care credit uses capped care expenses of $3,000 for one qualifying person or $6,000 for two or more, then applies the 2026 percentage scale. | Percentage falls as AGI rises | Nonrefundable |
| American Opportunity Credit | Up to $2,500 per eligible student, using 100% of first $2,000 plus 25% of next $2,000. | $80,000-$90,000 single/HOH/QSS; $160,000-$180,000 MFJ | 40% refundable in this estimate |
| Lifetime Learning Credit | 20% of up to $10,000 qualified expenses per return. | $80,000-$90,000 single/HOH/QSS; $160,000-$180,000 MFJ | Nonrefundable |
| Saver's Credit | Saver’s Credit rates are 50%, 20%, 10%, or 0% of eligible retirement contributions based on 2026 AGI thresholds. | 2026 AGI bands by filing status | Nonrefundable |
| Adoption Credit | 2026 adoption credit can reach $17,670, with up to $5,120 treated as refundable before the high-income phaseout. | $265,080-$305,080 MAGI phaseout | Partly refundable in 2026 |
Because several credits depend on MAGI and detailed eligibility tests, the result is an estimate, not a final Form 1040 computation. Use the credit-by-credit audit to see which assumption is driving the number.
U.S. Tax Credits: Nonrefundable, Refundable, and Phaseout Rules
What This Calculator Covers
This page fills the tax-credit workflow that is separate from taxable income, bracket-level federal tax, and refund planning. A tax credit changes the tax after deductions and brackets. Some credits only reduce tax; some can create a refund.
Rules were reviewed in May 2026: $2,200 per qualifying child under age 17, with up to $1,700 per child treated as potentially refundable through ACTC. AOTC can reach $2,500 per eligible student with a 40% refundable portion; Lifetime Learning Credit can reach $2,000 per return. 2026 adoption credit can reach $17,670, with up to $5,120 treated as refundable before the high-income phaseout.
Nonrefundable vs Refundable Credits
Nonrefundable credits are valuable only to the extent you have tax to offset. If your federal tax before credits is $2,000 and you have $4,000 of nonrefundable credits, the unused $2,000 generally does not become a refund unless a separate refundable rule applies. Refundable credits, such as EITC and parts of ACTC, AOTC, and adoption credit, are added after tax is reduced.
| Limit | Calculator treatment |
|---|---|
| Eligibility tests | The calculator does not validate SSN, residency, relationship, support, age, school, adoption finality, or Form 1098-T details. |
| MAGI differences | AGI is used as a practical proxy unless the credit has a different MAGI worksheet. Final returns should use the IRS worksheet for each credit. |
| Credit ordering | The estimate applies modeled nonrefundable credits in a practical sequence and shows unused credits. Final forms can include additional ordering rules. |
| Premium Tax Credit | ACA Premium Tax Credit is intentionally excluded because it needs Marketplace plan and household FPL inputs. |
When to Use Another Calculator First
This calculator expects tax before credits. If you are still deciding deductions, use the Taxable Income Calculator. If you need bracket tax, use the Federal Income Tax Calculator. If you already have final tax and payments and only need refund planning, use the Tax Refund Calculator.
