Common Tax Deductions Low and Middle Income Filers Miss
Five line items worth checking before you file.
You do not have to itemize to take these. They are "above-the-line" deductions that reduce your taxable income before the standard deduction. Most low and middle income filers miss at least one. Each one is worth real money.
1. Student loan interest
Up to $2,500 of interest paid on student loans, deductible without itemizing. Phases out at higher incomes. Your lender sends a 1098-E in January. Even if you are on an income-driven plan paying minimal interest, the small deduction reduces your tax.
2. HSA contributions
If you have a high-deductible health plan and an HSA, contributions are deductible up to $4,150 (single) or $8,300 (family) in 2026. Money goes in pre-tax, grows tax-free, comes out tax-free for medical expenses. The most powerful single tax shelter in U.S. law.
3. Traditional IRA contributions
Up to $7,000 ($8,000 if 50+) in deductible IRA contributions, assuming you meet income limits and do not have a workplace retirement plan. Even if you do have a workplace plan, partial deductions are available below certain income thresholds.
4. Self-employment expenses
If you freelanced or drove for Uber on the side, you can deduct ordinary business expenses:
- Vehicle mileage (67 cents/mile in 2026)
- Home office (simplified method: $5/sq ft up to 300 sq ft)
- Business phone, internet (the business-use portion)
- Software, supplies, contractor payments
- Health insurance premiums (if not subsidized through a spouse's employer)
5. Saver's Credit
Not a deduction - a tax credit. Lower-income workers who contribute to a 401(k) or IRA can claim 10-50% back as a credit. The income limits are roughly $39K single / $79K married for 2026. Many people who qualify do not know about it.
The credit vs deduction difference
A $1,000 deduction reduces your taxable income by $1,000. A $1,000 credit reduces your tax bill by $1,000. Credits are dramatically more valuable than deductions of the same size. Always look for credits first.
6. Child Tax Credit and Dependent Care
- Child Tax Credit: $2,000 per qualifying child under 17, partially refundable.
- Credit for Other Dependents: $500 for other qualifying dependents (older kids, parents you support).
- Dependent Care Credit: 20-35% of childcare costs up to a cap, if both parents work.
7. American Opportunity Tax Credit (AOTC)
If you, your spouse, or your dependent paid for college, the AOTC is worth up to $2,500 per student. Up to $1,000 of it is refundable (you get it even if you owe no tax). Hugely underclaimed.
Best practice
Even if you use a tax software that "asks" about each of these, walk through them manually. Read each question carefully. The software is good but it relies on you saying yes to questions whose answers you may not realize apply.
