The most commonly missed tax credits
After reviewing over 10,000 tax returns, I've identified the credits taxpayers miss most often. These oversights can cost you hundreds or thousands in lost refunds.
1. Earned Income Tax Credit (EITC)
Who misses it: Working individuals and families earning under $57,000
Why it's missed: Complex eligibility rules and fear it's "only for very low income"
2026 maximum amounts:
The IRS estimates 20% of eligible taxpayers don't claim EITC. Even if you don't have children, you might qualify for up to $600.
2. Child and Dependent Care Credit
Who misses it: Working parents who pay for childcare
Why it's missed: Assuming daycare FSA eliminates this credit (it doesn't always)
Credit amount: 20-35% of up to $6,000 in care expenses ($2,100 maximum)
Example: A couple earning $75,000 pays $8,000 for daycare. They can claim 20% of $6,000 = $1,200 credit, even if they also used a dependent care FSA.
3. Education credits (American Opportunity & Lifetime Learning)
Who misses it: College students, parents paying tuition, people in job training
Why it's missed: Not realizing credits apply to trade schools, professional development, or part-time students
Up to $1,000 of the American Opportunity Credit is refundable.
4. Retirement Savings Contributions Credit (Saver's Credit)
Who misses it: Low-to-moderate income workers who contribute to retirement
Why it's missed: Unaware the credit exists
Credit amount: 10%, 20%, or 50% of contributions up to $2,000 ($4,000 married)
Income limits (2026): $38,250 (single), $76,500 (married)
Example: Single taxpayer earning $35,000 contributes $1,000 to 401(k). Gets 20% credit = $200, plus the deduction for the contribution.
5. Premium Tax Credit (Health Insurance)
Who misses it: People who bought health insurance through Healthcare.gov but didn't reconcile advance payments
Why it's missed: Thinking advance payments covered everything
Potential benefit: Additional credit if your income was lower than estimated, or you qualify for more premium assistance
Less common but valuable credits
Red flags you might be missing credits
What you should do
1. Review the past 3 years — You can amend returns to claim missed credits
2. Use our return scanner to identify credits based on your specific situation
3. Keep better records — Save receipts for childcare, education, medical expenses
4. File even if you don't owe tax — You might qualify for refundable credits
Key takeaway: The average missed credit is worth $1,847 per return. The EITC alone provides an average of $2,541 to eligible families, but 1 in 5 eligible taxpayers don't claim it.
Key Takeaway: Most taxpayers miss at least one valuable credit worth $600-$7,830, with the EITC being the most commonly overlooked despite providing an average benefit of $2,541.

Best for parents who want to ensure they're claiming all family-related credits
Family credits you might be missing
Parents often focus on the Child Tax Credit but miss other valuable family credits that can add thousands to their refund.
Beyond the Child Tax Credit
While most parents know about the $2,000 Child Tax Credit, here are the family credits commonly missed:
Child and Dependent Care Credit:
Earned Income Tax Credit with children:
Education credits for your children
American Opportunity Tax Credit:
Example family: Parents with twins starting college can claim up to $5,000 in education credits ($2,500 × 2 students).
Special situation credits
Don't double-dip, but don't miss opportunities
You can often combine credits:
But you can't use the same expenses for multiple credits (e.g., can't use the same $3,000 in daycare costs for both FSA and the full Child Care Credit).
Key takeaway: Families with children commonly miss $3,000-$8,000 in combined credits beyond the basic Child Tax Credit, especially the Child Care Credit and education credits.
Key Takeaway: Parents often claim the Child Tax Credit but miss the Child and Dependent Care Credit, education credits, and enhanced EITC that can add $3,000-$8,000 to their refund.
