You filed. Refund landed, or a bill went out. Either way, you closed that tab and moved on with your week.
Chances are, somewhere on that return, money got left behind — not because you did something wrong, just because nobody flagged it.
According to IRS estimates, roughly $1.2 billion in refunds went unclaimed for tax year 2022 alone, with a median refund of $686 sitting untouched.The IRS estimates that approximately $1.2 billion in refunds remains unclaimed for taxpayers who have not filed their Form 1040 Federal income tax return for the 2022 tax year
That's just people who didn't file at all. Filers who did submit a return but skipped a deduction? That number isn't even fully tracked.
Why Deductions Slip Through Cracks
Software asks you questions based on patterns. If your situation doesn't match a common pattern, that box never pops up.
IRS data on the Earned Income Tax Credit alone shows roughly 1 in 5 eligible workers never claim it.The IRS estimates that roughly 1 in 5 eligible taxpayers do not claim the credit, leaving billions of dollars unclaimed And per IRS reporting, around 24 million eligible workers and families received about $70 billion in EITC for tax year 2024.Nationwide, as of December 2025, about 24 million eligible workers and families received about $70 billion in EITC. The average amount of EITC received nationwide in tax year 2024 was about $2,894.
That's a lot of money sitting unclaimed because nobody knew to ask.
If a refund feels small compared to your bigger money goals, that's fair — deductions are a piece of building real wealth from a regular paycheck, not a substitute for it. Still, a few hundred extra dollars a year, saved consistently, compounds into something that matters.
Once you know where to look, claiming these isn't complicated. Grab some tea, and walk through this with me.
1. State Sales Tax Instead of State Income Tax
Live somewhere without state income tax — Texas, Florida, Nevada, Tennessee, and a handful of others — and federal returns let you deduct state sales tax paid instead.This write-off makes sense primarily for those who live in states that do not impose an income tax
IRS provides tables based on income and location, so saving every receipt isn't required.
Big purchases change everything though. Buy a car, boat, or do major renovation work, and sales tax on those items stacks on top of table estimates.
If you're mapping out your annual money plan, factoring in sales tax savings gives a fuller picture of real take-home value.
2. Student Loan Interest Paid by Someone Else
This one trips people up constantly. Parent pays your loan, loan's in your name — IRS treats payment as if you made it.
Up to $2,500 in interest qualifies, and you don't need to itemize for it.
Young earners skip this because they assume only whoever physically sends the payment gets credit. Wrong assumption, real money left behind.
If student debt sits anywhere in your financial picture, strategies for paying off loans without wrecking your budget covers mistakes that cost thousands over time.
3. Job Search Costs (State-Level, For Some)
Federal deduction for job-hunting got cut for most filers years back. Several states still allow it though.
Resume printing, travel to interviews, career coaching fees — depending on your state, these may still count.
Self-employed folks chasing new contracts within their existing field might have options through business expense categories. Worth a quick chat with a tax pro rather than assuming nothing applies.
4. Home Office Deduction — Even Part-Time
Common belief: home office deduction only works if self-employed and working from home full-time.
Reality: regular and exclusive business use of part of your home — even part-time — opens up a portion of rent, utilities, and internet.The key to the home office tax deduction is to use part of your home or apartment regularly and exclusively for your moneymaking endeavor
| Expense Category | Potentially Deductible % |
|---|---|
| Rent/Mortgage Interest | Based on office square footage ratio |
| Utilities | Same ratio applied |
| Internet | Business-use percentage |
| Repairs (office area only) | 100% if exclusive to office |
| Homeowners Insurance | Based on square footage ratio |
Simplified method pays $5 per square foot, capped at 300 square feet — max deduction $1,500.Standard deduction of $5 per square foot of home used for business (maximum 300 square feet)
But run actual-expense math too. One comparison found a 150-square-foot office in a $2,500/month rental yields $750 under simplified versus $4,375 under actual expenses — a $3,625 gap.Simplified method: 150 sq ft x $5 = $750 deduction · Actual expense method: 150/1,200 = 12.5% business use. Annual rent $30,000 x 12.5% = $3,750. Add renter's insurance ($200/yr x 12.5% = $25), utilities ($3,600/yr x 12.5% = $450), and internet ($1,200/yr x 12.5% = $150). Total actual deduction: $4,375 · Difference: $3,625 more with the actual expense method At a 24% bracket, that's roughly $870 in extra savings, just from picking the right method.At a 24% marginal rate, that is $870 in additional tax savings per year
5. Charitable Mileage and Out-of-Pocket Costs
Donating clothes or cash sticks in memory. Driving for charity rarely does.
Volunteer regularly — appointments, meal delivery, errands for a nonprofit — and mileage adds up at 14 cents per mile under current charitable rates.
Supplies bought for an event, ingredients for a fundraiser bake sale, anything unreimbursed — counts too.
Keep a notebook in your glovebox. Genuinely, that's enough tracking.
6. Health Insurance Premiums for Self-Employed Folks
Self-employed and paying your own health insurance? Premiums may be fully deductible, no itemizing needed.
This covers medical, dental, and qualifying long-term care for you, a spouse, and dependents — and one analysis breaks down how this deduction works even for freelance income reported on a 1099.Most self-employed people know about the home office deduction, but they may overlook a bigger benefit: deducting up to 100% of health, dental, vision, and long-te
Side hustlers often assume self-employed deductions only apply to "real businesses." Freelance gig income counts just as much.
7. Prior-Year State Refund (Reporting It Right)
This one runs backward — it's about not under-reporting income.
Itemized last year and got a state refund? That refund might count as taxable income this year.
Switch software providers or file by hand, and that detail can vanish quietly — until a notice arrives months later asking for additional tax plus interest.
8. Educator Expenses
Teachers spend personal money on classroom supplies constantly — pencils, books, snacks for kids who skipped breakfast.
Eligible K-12 educators can deduct up to $300 in unreimbursed classroom costs for 2025, rising to $350 for 2026, even without itemizing.The Educator Expense Deduction allows eligible educators to deduct up to $300 worth of qualified expenses from their income for the 2025 tax year ($350 for 2026)
This applies to teachers, instructors, counselors, principals, and aides working at least 900 hours during a school year.If you're an eligible educator, you can deduct up to $300 ($600 if married filing jointly and both spouses are eligible educators, but not more than $300 each) of unreimbursed trade or business expenses
There's even a bill in Congress aiming to raise that cap to $1,000 for 2026.Under the bill, an eligible educator may deduct up to $1,000 in 2026 for unreimbursed expenses for classroom supplies and certain professional development Worth watching if you're in education.
9. Energy-Efficient Home Improvements
New windows, insulation, heat pump, solar panels recently?
Federal credits exist for qualifying upgrades — and credits cut your bill dollar-for-dollar, which beats a deduction.
Energy.gov keeps updated lists since rules shift based on current legislation.
Homeowners often assume these expired or only ran during a narrow pandemic-era window, missing extensions that kept programs alive.
10. Dependent Care for Adult Dependents
Child care credit gets attention. Adult dependent care gets ignored.
Paying for an aging parent's care or a disabled adult relative's daycare so you can work? In-home aide costs may qualify under Child and Dependent Care Credit — despite that name suggesting kids only.
Income limits apply, and dependent-status rules get specific, so checking IRS guidance or a tax pro before claiming matters here.
How Much Could This Realistically Add Up To?
Say you qualify for three: parent-paid student loan interest, home office (simplified, 150 sq ft), and educator expenses.
Student loan interest: up to $2,500 off taxable income.
Home office: $750.
Educator expenses: $300.
Total: $3,550 reduction in taxable income.
Depending on bracket, that's several hundred dollars back. Money like that, saved with intention, builds toward an emergency cushion or knocks debt down faster.
"An investment in knowledge pays the best interest." — Benjamin Franklin
Tax knowledge counts too.
Software vs Professional Help
Tax software gets smarter yearly, asking sharper questions.
But software runs off what you tell it. Skip a prompt about adult dependent care or charitable mileage, and that deduction stays buried.
A CPA, Mark Luscombe, put it plainly regarding EITC: "a lot of people who are entitled to it are not claiming it.""a lot of people who are entitled to it are not claiming it," says Mark Luscombe, a certified public accountant (CPA) and principal federal tax analyst at Wolters Kluwer Tax and Accounting
One-time professional consult, especially for self-employed folks, property owners, or anyone juggling multiple income streams, often pays for itself through what gets caught.
Setting Up for Next Year — Now, Not in April
Don't wait until filing season to think about this.
Start a folder, physical or digital, and drop receipts, mileage logs, statements into it as the year goes.
Categories worth tracking: medical expenses, charitable activity including mileage, education costs, home office expenses if self-employed, energy-efficient upgrades.
That single habit turns tax season from scramble into quick review.
If getting out of debt faster sits anywhere on your goal list, every recovered dollar can go straight there.
Where This Leaves You
Tax code wasn't built to be intuitive. It rewards people who know rules exist, not necessarily people earning more or spending carefully.
These 10 situations cover scenarios far more common than people assume: parents helping with loans, side hustles, volunteer work, teachers buying supplies, families caring for aging relatives.
None require deep tax knowledge. Just a habit of asking "does this count?" instead of assuming no.
And if your refund situation feels tied up with bigger questions — debt, savings goals, what financial freedom even looks like for your household — those threads connect more than people realize.
For Nigerian readers building US-facing income streams or comparing remittance and multi-currency options, platforms like those covered in our Wise vs Raenest comparison sometimes intersect with how foreign-earned income gets reported, though that's a separate conversation worth its own deep dive.
A low-income budget framework can also help if extra refund money needs a clear destination instead of disappearing into daily spend.
