Getting the largest possible tax refund comes down to two things: claiming every deduction and credit you qualify for, and making sure enough tax is withheld from your paychecks throughout the year. Most people leave money on the table by overlooking credits worth hundreds or thousands of dollars, or by not adjusting their withholding to match their actual tax situation. Here’s how to make sure you’re not one of them.
Choose the Right Deduction Method
Every taxpayer gets a choice: take the standard deduction or itemize individual expenses. For the 2026 tax year, the standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household. If your itemizable expenses (mortgage interest, state and local taxes, charitable donations, medical costs above a threshold) add up to more than your standard deduction, itemizing saves you more. If they don’t, the standard deduction wins.
A quick way to check: add up your mortgage interest statement, your property tax bills, and your charitable giving receipts. If that total alone is close to or above your standard deduction amount, pull together the rest of your deductible expenses and run the numbers both ways. Tax software will usually do this comparison automatically and recommend whichever method gives you a bigger refund.
Claim Every Tax Credit You Qualify For
Credits are more powerful than deductions because they reduce your tax bill dollar for dollar rather than just lowering your taxable income. Some credits are refundable, meaning you get the money even if you owe zero tax. These are the biggest refund boosters.
The Child Tax Credit is worth up to $2,200 per qualifying child under age 17. Up to $1,700 of that is refundable through the Additional Child Tax Credit, so even if your income is low enough that you don’t owe federal tax, you can still receive up to $1,700 per child as a refund.
The Earned Income Tax Credit is designed for low- and moderate-income workers and can be worth several thousand dollars depending on your income and number of children. To qualify, your investment income must be under $11,950, and your earned income must fall below certain thresholds that range from roughly $19,000 for a single filer with no children to nearly $69,000 for a married couple with three or more kids. The EITC is fully refundable, so it goes straight into your refund. The IRS estimates that millions of eligible taxpayers fail to claim it each year simply because they don’t realize they qualify.
The American Opportunity Tax Credit covers up to $2,500 per year in college tuition and fees for students in their first four years of higher education. Forty percent of it (up to $1,000) is refundable. The Lifetime Learning Credit covers up to $2,000 for any post-secondary education, though it’s not refundable. If you or a dependent is in school, one of these credits likely applies.
Use Above-the-Line Deductions
Some deductions reduce your adjusted gross income (AGI) regardless of whether you itemize or take the standard deduction. These are sometimes called “above the line” because they appear before the line on your return where AGI is calculated. Lowering your AGI can increase your refund directly and can also help you qualify for income-based credits that phase out at higher income levels.
Common above-the-line deductions include contributions to a traditional IRA, student loan interest (up to $2,500 per year), health savings account contributions, and self-employment tax. Starting with the 2026 tax year, several new deductions are available to all taxpayers regardless of itemizing status. Taxpayers age 65 and older can claim an additional $6,000 deduction. Workers who receive tips may deduct up to $25,000 in qualified tip income. Individuals can deduct up to $12,500 in qualified overtime pay ($25,000 for joint filers). And anyone with a car loan can deduct up to $10,000 in qualified passenger vehicle loan interest.
These new deductions are significant. If you’re a tipped worker earning $40,000 a year with $15,000 of that coming from tips, that deduction alone could reduce your tax bill by $1,800 or more depending on your bracket.
Don’t Miss Home Energy Credits
If you made improvements to your home, two credits are easy to overlook. The Energy Efficient Home Improvement Credit covers 30% of the cost of qualifying upgrades like new windows, exterior doors, insulation, central air conditioners, water heaters, and heat pumps. The annual cap is $1,200 for most improvements, with a separate $2,000 limit for heat pumps, biomass stoves, and boilers. There’s no lifetime limit, so you can claim the credit year after year as you make improvements.
The Residential Clean Energy Credit covers 30% of the cost of solar panels, solar water heaters, wind turbines, geothermal systems, and battery storage with no annual maximum or lifetime limit. A $20,000 solar installation would generate a $6,000 credit. Homeowners get the most benefit, but renters can also qualify for certain improvements. The home must be one you use as a residence, so rental properties you don’t live in don’t count.
Adjust Your Withholding
Your refund is essentially the difference between what was withheld from your paychecks and what you actually owe. If too little is withheld, you’ll owe money at tax time. If too much is withheld, you get a larger refund. You control this through Form W-4, which you can update with your employer at any time during the year.
The W-4 determines your withholding based on your filing status, the number of allowances you claim, and any additional amount you request to be withheld per paycheck. To increase your refund, you can request additional withholding on line 4(c) of the form. For example, asking your employer to withhold an extra $50 per paycheck adds $1,300 to your annual withholding over 26 pay periods, which translates roughly to an extra $1,300 in your refund if your tax situation stays the same.
The IRS offers a Tax Withholding Estimator on its website that walks you through your expected income, deductions, and credits for the year and tells you exactly how to fill out your W-4 to hit a target refund. Running this tool early in the year gives you the most pay periods to spread any adjustments across, so the per-paycheck impact is smaller.
Contribute to Tax-Advantaged Accounts
Money you put into a traditional IRA or a traditional 401(k) reduces your taxable income for the year. If you’re in the 22% tax bracket and contribute $5,000 to a traditional IRA before the filing deadline, that’s $1,100 less in tax, which increases your refund by the same amount. You can make IRA contributions for the prior tax year all the way up until the April filing deadline, so even after December 31 you still have a few months to boost your refund.
Health savings account contributions work the same way if you have a qualifying high-deductible health plan. HSA contributions are deductible above the line, and withdrawals for medical expenses are tax-free, making them one of the most tax-efficient accounts available.
File Accurately and On Time
Errors on your return are one of the most common reasons refunds get delayed or reduced. Double-check Social Security numbers for every person listed, make sure your bank routing and account numbers are correct for direct deposit, and verify that income reported on your W-2s and 1099s matches what you enter. E-filing with direct deposit is the fastest combination, typically delivering refunds within 21 days.
If you’re eligible for free filing, use IRS Free File (available to taxpayers with AGI at or below a certain threshold) or IRS Direct File to avoid paying preparation fees that eat into your refund. Keeping more of your refund is just as valuable as making it bigger in the first place.
