Every year, millions of working families overpay on their taxes simply because they don't know which deductions they qualify for. The tax code is complex, and it's easy to leave money on the table without expert guidance. Here are five of the most commonly missed tax deductions for working families — and how claiming them could put hundreds or even thousands of dollars back in your pocket.
1. Child and Dependent Care Credit
If you pay for childcare so you can work or look for work, you may qualify for the Child and Dependent Care Credit. This credit can offset up to $3,000 in expenses for one child or $6,000 for two or more children. Despite being one of the most valuable credits available to families, it is frequently overlooked.
Eligible expenses include daycare, after-school programs, summer day camps, and even in-home care providers like nannies or babysitters. The credit percentage depends on your income, so families across a wide range of earnings may qualify. Many families mistakenly believe this credit only applies to full-time daycare — but any qualifying care arrangement counts.
2. Home Office Deduction
If you work from home — even part of the time — you may be entitled to claim a home office deduction. This is one of the most misunderstood deductions in the tax code. Many taxpayers assume it only applies to self-employed individuals, but employees who work remotely and have a dedicated workspace may also qualify under certain circumstances.
The home office deduction allows you to write off a portion of your rent or mortgage, utilities, internet, and home repairs proportional to the square footage of your dedicated workspace. The simplified method lets you deduct $5 per square foot up to 300 square feet, making recordkeeping straightforward. If your home office is 200 square feet, that's a $1,000 deduction right there.
For self-employed taxpayers and small business owners, this deduction can be especially significant. The key requirement is that the space must be used regularly and exclusively for business purposes.
3. Education Credits and Student Loan Interest
Families investing in education often miss out on valuable credits. The American Opportunity Tax Credit (AOTC) provides up to $2,500 per eligible student for the first four years of higher education. Up to $1,000 of this credit is refundable, meaning you can receive money back even if you owe no taxes.
The Lifetime Learning Credit offers up to $2,000 per tax return for qualified tuition and related expenses, with no limit on the number of years you can claim it. This makes it ideal for parents taking continuing education courses or graduate students.
Additionally, if you're paying off student loans, you can deduct up to $2,500 in student loan interest per year — even if you don't itemize. Many families forget to claim this deduction because it doesn't require a separate schedule. It's an above-the-line deduction that directly reduces your adjusted gross income.
4. Earned Income Tax Credit (EITC)
The Earned Income Tax Credit is one of the largest anti-poverty tax tools available to working families, yet the IRS estimates that millions of eligible taxpayers fail to claim it every year. For the 2025 tax year, the EITC can be worth up to $7,830 for families with three or more qualifying children.
Eligibility is based on income, filing status, and the number of qualifying children. Self-employed parents and part-time workers often assume they don't qualify — but many do. Even workers without children may qualify for a smaller credit. If your income dropped significantly this year due to job loss, reduced hours, or a career change, you may now qualify when you didn't before.
The EITC is fully refundable, which means if the credit exceeds what you owe in taxes, the IRS sends you the difference as a refund. This makes it one of the most impactful credits for low- to moderate-income working families.
5. Medical and Dental Expenses
If your out-of-pocket medical and dental expenses exceed 7.5% of your adjusted gross income, you can deduct the amount above that threshold when you itemize. For a family with a $60,000 AGI, that means expenses above $4,500 are deductible. In years with major medical events — surgery, orthodontics, prescription costs, mental health treatment — this deduction can add up quickly.
Eligible expenses include doctor visits, prescription medications, dental and vision care, hearing aids, mental health services, and even some home modifications for disability. Premiums you pay for health insurance out of pocket (not through an employer) also count. Keep all medical receipts throughout the year so you're prepared to claim every qualifying dollar.
Families who use a Health Savings Account (HSA) or Flexible Spending Account (FSA) should also make sure they're contributing the maximum allowed. Contributions to these accounts are pre-tax, effectively reducing your taxable income automatically — no itemizing required.
