Tax Credit
Tax Credit
Quick Definition
A tax credit is a direct, dollar-for-dollar reduction in the amount of tax you owe. Unlike a deduction (which reduces taxable income), a tax credit reduces your actual tax bill directly. A $2,000 tax credit saves exactly $2,000 in taxes regardless of your tax bracket.
What It Means
Tax credits are the most powerful form of tax relief available. The federal government uses them to incentivize specific behaviors (education, childcare, clean energy, retirement saving) and to provide targeted relief to lower and middle-income households.
The difference between a credit and a deduction at various tax rates:
| Amount | Deduction at 12% | Deduction at 22% | Deduction at 37% | Credit |
|---|---|---|---|---|
| $1,000 | Saves $120 | Saves $220 | Saves $370 | Saves $1,000 |
| $5,000 | Saves $600 | Saves $1,100 | Saves $1,850 | Saves $5,000 |
A credit is worth 2.7x to 8.3x more than an equivalent deduction depending on your bracket.
Types of Tax Credits
Refundable Credits
Can reduce your tax below zero. You receive the excess as a cash refund even if you owe no tax:
| Credit | Maximum (2026) | Notes |
|---|---|---|
| Earned Income Tax Credit (EITC) | Up to $8,231 (3+ children) | Phase-in and phase-out with income |
| Additional Child Tax Credit | Up to $1,700 per child | Refundable portion of Child Tax Credit |
| American Opportunity Tax Credit (refundable portion) | 40% refundable (up to $1,000) | First 4 years of higher education |
| Premium Tax Credit | Varies | ACA marketplace insurance subsidy |
Nonrefundable Credits
Can reduce your tax to zero but not below. Any excess credit is lost:
| Credit | Maximum | Notes |

| Adoption Credit | Up to $17,280 (2026 est.) | For qualified adoption expenses |
| Foreign Tax Credit | Taxes paid to foreign countries | Prevents double taxation |
Partially Refundable Credits
| Credit | Refundable Portion |
|---|---|
| Child Tax Credit | Up to $1,700 per child (Additional CTC) |
| American Opportunity Credit | 40% (up to $1,000) |
Major Tax Credits in Detail
Child Tax Credit (2026)
The OBBBA made the $2,200 per-child credit permanent and tied it to inflation starting after tax year 2025. The 2026 amount remains $2,200 because the inflation indexing rounds down to the nearest $100, and inflation was not large enough to push the indexed value to $2,300.
Key rules for 2026:
| Feature | Amount |
|---|---|
| Maximum credit per child | $2,200 |
| Refundable portion (ACTC) | Up to $1,700 per child |
| Phase-out threshold (single) | $200,000 AGI |
| Phase-out threshold (MFJ) | $400,000 AGI |
| Phase-out rate | $50 per $1,000 AGI above threshold |
| Minimum earned income for ACTC | $2,500 |
| Child age limit | Under 17 at end of tax year |
SSN requirement (new since 2025): To claim the CTC or ACTC, the taxpayer (or at least one spouse on a joint return) must have a valid Social Security number issued before the return due date. Households filing with an ITIN for the parent no longer qualify for the $2,200 credit, even if the child has a valid SSN. They may still qualify for the $500 Credit for Other Dependents.
A single filer with one child loses the entire credit at $244,000 AGI. A joint filer with two children loses it at $488,000 AGI.
Earned Income Tax Credit (2026)
The largest anti-poverty tax program in the U.S., providing significant refundable credits to low-to-moderate income workers:
| Filing Status & Children | Max Income (2026, Single) | Max Income (2026, MFJ) | Max Credit |
|---|---|---|---|
| Single, no children | $19,540 | $26,820 | $664 |
| Single, 1 child | $51,593 | $58,863 | $4,427 |
| Single, 2 children | $58,629 | $65,899 | $7,316 |
| Single, 3+ children | $62,974 | $70,244 | $8,231 |
The EITC is fully refundable. Workers who qualify receive the full credit even with zero tax liability.
Investment income limit: For 2026, you cannot claim the EITC if investment income (interest, dividends, capital gains, rental income) exceeds $12,200. This is a hard cliff, not a gradual phase-out. $12,199 and you qualify. $12,201 and the credit disappears entirely.
Age requirement for childless workers: Must be between 25 and 64 years old at the end of the year. Workers outside this range without qualifying children cannot claim the credit regardless of how little they earned.

Residential Clean Energy Credit (Solar)
30% of the cost of solar panels, battery storage, and other clean energy equipment installed through 2032. On a $25,000 solar installation: $7,500 tax credit. The credit reduces federal income tax owed. If the credit exceeds the tax owed, the excess carries forward to future years.
EV Tax Credit
Up to $7,500 for new qualifying electric vehicles (income limits: $150K single / $300K MFJ; vehicle MSRP limits apply). A $4,000 credit is also available for qualifying used EVs. The credit can be claimed at the point of sale as a dealer discount starting in 2024, eliminating the need to wait for tax season.
How Credits Interact with Tax Owed
Example: Single taxpayer with $20,000 taxable income (tax owed: approximately $2,200) who qualifies for $3,000 in credits:
| Credit Type | Tax Owed Before | Credit Applied | Result |
|---|---|---|---|
| Nonrefundable ($3,000) | $2,200 | -$2,200 | Tax = $0; $800 lost |
| Refundable ($3,000) | $2,200 | -$3,000 | Tax = $0 + $800 refund |
Nonrefundable credits can only reduce tax to zero. The extra $800 is lost. Refundable credits pay out the excess as a cash refund.
Tax Credits vs. Tax Deductions: Summary
| Feature | Tax Credit | Tax Deduction |
|---|---|---|
| Reduces | Tax owed | Taxable income |
| Value | Dollar-for-dollar | Rate x deduction amount |
| Bracket-dependent? | No | Yes |
| Can go negative (refundable)? | Some | No |
| Examples | Child Tax Credit, EITC, EV credit | Mortgage interest, IRA, charitable |
Key Points to Remember
- Tax credits are dollar-for-dollar reductions in tax owed, far more valuable than equivalent deductions.
- The Child Tax Credit is $2,200 per child for 2026, made permanent by the OBBBA. Up to $1,700 per child is refundable.
- The EITC reaches up to $8,231 for families with 3+ children in 2026. It is fully refundable.
- A new SSN requirement for the CTC began in tax year 2025: at least one parent must have a valid SSN.
- The Residential Clean Energy Credit offers 30% back on solar, batteries, and other clean energy through 2032.
- EV credits up to $7,500 are available for qualifying new vehicles and can be applied at the point of sale.
Common Mistakes to Avoid
- Not claiming the EITC: Millions of eligible workers fail to claim it each year. The IRS estimates approximately 20% of eligible taxpayers miss it, especially those with self-employment income, multi-state filings, or unusual income situations.
- Assuming nonrefundable credits are worthless if your tax is low: They still save taxes up to the amount owed. A $2,200 Child Tax Credit against $1,500 in tax liability still saves you $1,500.
- Forgetting clean energy credits: Solar, heat pumps, and EV chargers all qualify for meaningful credits that dramatically improve the economics of clean energy adoption.
- Missing the SSN requirement for CTC: Starting with tax year 2025, households where neither parent has a valid SSN cannot claim the $2,200 Child Tax Credit. Check eligibility before filing.
- Exceeding the EITC investment income cliff: $12,200 in investment income disqualifies you entirely. If you are near the limit, consider timing capital gains realizations carefully.

Frequently Asked Questions
Q: Do tax credits reduce state taxes? A: Federal tax credits only reduce federal income tax. Many states have their own separate tax credit programs. Some state credits mirror federal credits; others are unique to the state.
Q: Can I carry forward unused nonrefundable credits? A: Some nonrefundable credits (like the Residential Clean Energy Credit) can be carried forward. Others cannot. Check the specific credit rules. Many are "use it or lose it" in the current year.
Q: What is a "tax credit" vs. a "tax rebate"? A: A tax credit is a reduction in taxes owed through the tax filing process. A rebate is a direct payment from the government, often not tied to tax filing. The 2021 COVID stimulus payments were structured as advance payments of a tax credit. The distinction matters for timing and phase-out calculations.
Q: Did the Child Tax Credit change for 2026? A: The OBBBA made the $2,200 per-child amount permanent and tied it to inflation. The 2026 amount stays at $2,200 because the inflation adjustment did not cross the next $100 rounding threshold. The refundable portion (ACTC) remains up to $1,700 per child. A new SSN requirement for parents began with tax year 2025 and remains in effect for 2026.
