My Neighbor Got a $6,500 Tax Refund While I Got $400 — The Federal Tax Credits She Claimed That I Ignored

Last April, my neighbor Rosa sat at her kitchen table and walked me through her tax return — a refund of $6,512. Mine? A flat $400. We earn roughly the same salary, have similar family sizes, and both use the same filing software. The difference wasn’t income. It was that Rosa had methodically claimed five federal tax credits she’d researched over three years of trial and error. I had claimed one. That conversation changed how I approach taxes permanently.

For the 2025 tax year — returns filed in 2026 — several of those same credits are still available, and the IRS estimates that roughly 20% of eligible Americans never claim the Earned Income Tax Credit alone, leaving approximately $9 billion unclaimed annually. This listicle covers seven credits worth knowing, with real eligibility figures, income thresholds, and honest trade-offs for each.

1. Earned Income Tax Credit (EITC) — Up to $7,830

The EITC is the single most valuable refundable credit for working low-to-moderate income Americans, and it remains the most frequently missed. For the 2025 tax year, the maximum credit is $7,830 for families with three or more qualifying children. Even filers with no children can claim up to $632.

Eligibility depends on earned income, investment income limits (capped at $11,600 for 2025), filing status, and the number of qualifying children. Income limits for married filing jointly with three children reach approximately $66,819. According to the IRS EITC information center, the credit phases in as income rises, peaks, then phases out — meaning workers at both ends of the income range may receive a smaller credit than those in the middle range.

• Refundable: Yes — you can receive this money even if you owe zero tax
• Who misses it: Self-employed workers who don’t realize net earnings count as earned income
• Common mistake: Not claiming it after a job loss or reduced hours year

Pros: Fully refundable, no cap on refund size, accessible to self-employed workers. Cons: Requires careful documentation of all earned income; errors trigger IRS audits at a higher rate than most other credits.

2. Child Tax Credit (CTC) — Up to $2,000 Per Child

For the 2025 tax year, the Child Tax Credit offers up to $2,000 per qualifying child under age 17, with up to $1,700 of that amount refundable as the Additional Child Tax Credit (ACTC). The income phase-out begins at $200,000 for single filers and $400,000 for married filing jointly.

A qualifying child must be under 17 at the end of the tax year, a U.S. citizen, national, or resident alien, and must have lived with you for more than half the year. The child must also have a valid Social Security number — Individual Taxpayer Identification Numbers (ITINs) do not qualify for the refundable portion, a detail that catches many immigrant families off guard.

Pros: Straightforward eligibility, large dollar value per child, partially refundable. Cons: The refundable portion requires earned income of at least $2,500 to start phasing in; families without W-2 income may receive less than expected.

3. Child and Dependent Care Credit — Up to $3,000 (One Dependent) or $6,000 (Two or More)

This credit covers a percentage of what you paid for childcare, after-school programs, or adult dependent care that allowed you — and your spouse, if married — to work or look for work. For 2025, eligible expenses are capped at $3,000 for one qualifying person and $6,000 for two or more. The percentage you can claim ranges from 20% to 35% depending on your adjusted gross income.

At the lowest income levels (AGI under $15,000), the credit reaches 35% of expenses — meaning up to $2,100 for one dependent or $2,100 for two. As income rises above $43,000, the rate drops to the floor of 20%. Unlike the EITC, this credit is nonrefundable for most filers, which means it can reduce your tax liability to zero but won’t generate a refund by itself.

• Qualifying care includes daycare centers, babysitters, before/after-school programs, and summer day camps
• Overnight camps do not qualify
• Care for a spouse or dependent who is physically or mentally incapable of self-care also qualifies
• You must include the care provider’s Tax ID number on your return

Pros: Covers a wide range of care arrangements, including some in-home care. Cons: Nonrefundable for most filers; requires detailed recordkeeping of provider payments and Tax IDs.

4. American Opportunity Tax Credit (AOTC) — Up to $2,500

The AOTC is arguably the most generous education credit available, worth up to $2,500 per eligible student for the first four years of post-secondary education. It covers 100% of the first $2,000 in qualified education expenses and 25% of the next $2,000. Critically, 40% of the credit (up to $1,000) is refundable, so even students with no tax liability can receive a check.

Income limits apply: the full credit is available to single filers with MAGI under $80,000 and married filers under $160,000, phasing out completely at $90,000 and $180,000 respectively. The student must be enrolled at least half-time in a degree or credential program at an eligible institution, and must not have a felony drug conviction. According to the IRS AOTC page, the credit can only be claimed for four tax years per student.

Pros: Partially refundable, covers tuition AND required course materials. Cons: Limited to four years total; graduate students must use the Lifetime Learning Credit instead, which maxes at $2,000 and is nonrefundable.

5. Energy Efficient Home Improvement Credit — Up to $3,200 Per Year

Under the Inflation Reduction Act provisions that remain active for 2025, homeowners can claim up to $3,200 annually for qualifying energy-efficient upgrades. This includes up to $1,200 for insulation, windows, doors, and energy audits, plus a separate $2,000 credit for heat pumps and biomass stoves.

Unlike previous versions of this credit, there is no lifetime cap — only an annual cap of $3,200. This means a homeowner who replaced their HVAC in 2024 can claim again in 2025 for new windows or insulation. The credit applies to primary residences only (not new construction or rental properties), and the improvements must meet current energy efficiency standards set by the Department of Energy.

Pros: Repeatable annually with no lifetime cap, covers a broad range of improvements. Cons: Nonrefundable only; renters and landlords cannot claim it for rental units.

6. Saver’s Credit — Up to $1,000 ($2,000 if Married Filing Jointly)

The Retirement Savings Contributions Credit — commonly called the Saver’s Credit — rewards low-to-moderate income earners for contributing to a 401(k), IRA, SIMPLE IRA, or ABLE account. The credit is worth 10%, 20%, or 50% of your contributions, up to $2,000 per person ($4,000 for married couples), depending on income.

For 2025, the maximum credit of 50% applies to single filers with AGI under $23,000 and joint filers under $46,000. The credit phases out entirely above $38,250 (single) and $76,500 (married). This is one of the least-claimed credits in the tax code — according to the IRS Saver’s Credit resource, only a fraction of eligible households claim it each year.

• You must be 18 or older, not a full-time student, and not claimed as a dependent
• Contributions to a Roth IRA count even though withdrawals are tax-free
• Rollovers from one retirement account to another do not count

Pros: Stacks on top of any deduction you already get for traditional IRA or 401(k) contributions. Cons: Nonrefundable; if your tax liability is already zero, you won’t see this as a refund.

7. Premium Tax Credit — Varies Based on Income and Plan

If you purchased health insurance through the federal or state marketplace and your household income falls between 100% and 400% of the federal poverty level — or above 400% under the enhanced provisions extended through 2025 — you may qualify for the Premium Tax Credit. This credit directly lowers your monthly insurance premium, either in advance or as a lump sum at filing.

For a family of four in 2025, the federal poverty level is approximately $31,200. The credit ensures you pay no more than a capped percentage of your income toward the benchmark silver plan. Families who received advance payments must reconcile on their return using Form 8962 — those who underestimated income may owe back some of the credit, while those who overestimated may receive additional money.

Pros: Refundable, applies to health insurance costs that affect nearly every household, available regardless of employment status. Cons: Requires annual reconciliation; income changes during the year that aren’t reported to the marketplace can create an unexpected tax bill.

The Three Credits Worth Prioritizing First

If you can only focus on three credits this filing season, start with these — they offer the highest dollar value, the broadest eligibility, and the most direct path to a larger refund.

Final Verdict: What Rosa Did That I Didn’t

Rosa didn’t have a special accountant or insider IRS knowledge. She spent two hours before filing season reading through the IRS Interactive Tax Assistant and checking every credit category against her actual situation. She claimed the EITC, the Child Tax Credit, the Child and Dependent Care Credit, and the energy credit for a heat pump she installed the previous fall.

The total difference was $6,112. None of those credits required income she didn’t have, children she didn’t raise, or expenses she didn’t already make. The only difference was documentation and awareness. The IRS does not notify you when you’re eligible for a credit you haven’t claimed — that responsibility falls entirely on the filer.

If you believe you missed credits on a prior year return, you have three years from the original filing deadline to amend using Form 1040-X. For the 2022 tax year, that window closes in April 2026. Act before that deadline passes.
