The biggest refund comes from claiming every deduction and credit you actually may have access to for, not from tricks or shortcuts
A larger tax refund is not about gaming the system — it is about making sure the IRS does not keep money that belongs to you. The size of your refund depends on two things: how much tax you overpaid during the year (through withholding or estimated payments), and which deductions and credits reduce the tax you owe. Most people can increase their refund by finding deductions they missed, claiming all available credits, and adjusting their withholding so less money is taken from each paycheck.
The IRS does not reward you for a large refund. A big refund actually means you lent the government your money interest-free all year. The goal is not the biggest number — it is the right number, where you owe nothing and receive nothing back. But if you are currently getting a small refund or owing money, the steps below will help you understand where that money is going and what you can change.
Key Takeaways
- Deductions reduce the income you pay tax on, and credits reduce the tax itself — credits are worth more, so find them first.
- Common missed deductions include student loan interest, educator expenses, and unreimbursed work costs if you are self-employed.
- If you are married filing jointly, make sure both spouses claim all credits they are may have access to to, including child and dependent credits.
- Adjusting your W-4 form at work changes how much tax is withheld from your paycheck, which directly affects your refund size.
- Using tax software or a tax preparer who knows your full situation catches deductions and credits you might miss on your own.
Understand the difference between deductions and credits
A deduction reduces the amount of income you pay tax on. If you earn $50,000 and claim $5,000 in deductions, you only pay tax on $45,000. A credit reduces the tax bill itself. A $1,000 credit means you owe $1,000 less in tax, no matter what your income is. Because credits directly lower what you owe, they are worth more than deductions of the same dollar amount.
Most people use the standard deduction, which is a flat amount the IRS lets you subtract from your income. For 2024, the standard deduction is $14,600 for single filers and $29,200 for married couples filing jointly — these amounts change each year. If your deductions add up to less than the standard deduction, you do not benefit from listing them separately. If they add up to more, you can choose to itemize instead, listing deductions like mortgage interest, property taxes, and charitable donations on Schedule A.
Credits are where most people find money they did not know they had. Common credits include the Earned Income Tax Credit (EITC) for lower-income workers, the Child Tax Credit for each dependent child, the American Opportunity Credit for education expenses, and the Saver's Credit if you contribute to a retirement account. Each has different income limits and requirements, but if you meet them, the credit comes straight off your tax bill.
Find deductions you may have overlooked
Beyond the standard deduction, certain expenses reduce your taxable income. If you are self-employed, you can deduct business expenses like supplies, equipment, and a portion of your home office. If you are an employee, you can deduct unreimbursed work expenses only if you itemize — and only if they exceed 2% of your adjusted gross income, which makes this deduction rare for most workers.
Student loan interest up to $2,500 per year is deductible even if you take the standard deduction. Educator expenses up to $300 per year are deductible if you teach in a public or private school. If you are self-employed and pay for your own health insurance, that premium is deductible. If you made contributions to a traditional IRA or a SEP-IRA, those contributions may be deductible depending on your income and whether you have access to a workplace retirement plan.
Charitable donations are deductible only if you itemize, and only the amount above the standard deduction matters. If you own a home, mortgage interest and property taxes are deductible if you itemize. State and local taxes (SALT) are deductible up to $10,000 per year if you itemize. The key question for each deduction is whether the total of all your itemized deductions exceeds the standard deduction — if not, the standard deduction is the better choice.
Claim all credits you are may have access to to
The Child Tax Credit is $2,000 per child under age 17, and you can claim it if your income is below certain limits. The Earned Income Tax Credit ranges from a few hundred to several thousand dollars depending on your income and family size, and it is designed for workers with low to moderate income. The American Opportunity Credit covers up to $2,500 of education expenses per student per year if you are paying for college or university. The Lifetime Learning Credit covers up to $2,000 of education expenses and has higher income limits than the American Opportunity Credit.
If you have a dependent adult or elderly relative living with you, the Credit for Other Dependents is $500 per person. If you paid for childcare so you could work, the Child and Dependent Care Credit covers a portion of those expenses. If you contributed to a traditional or Roth IRA, the Saver's Credit may give you a credit of up to $1,000 if your income is below certain limits. Each credit has income thresholds and specific requirements, so check whether you meet them before claiming.
Many credits are refundable, meaning if the credit is larger than the tax you owe, the IRS sends you the difference. The Earned Income Tax Credit and the American Opportunity Credit are partially refundable, which is why they often result in large refunds for people who may have access to. Non-refundable credits can only reduce your tax bill to zero — they cannot create a refund.
Adjust your withholding if you consistently get large refunds
Your employer withholds tax from each paycheck based on the W-4 form you filled out when you started the job. If you get a large refund every year, it means too much tax is being withheld. You can adjust this by updating your W-4 to claim more allowances or to have less withheld. The IRS provides a withholding calculator on its website (irs.gov) that asks about your income, deductions, and credits and tells you what to enter on your W-4.
Adjusting your withholding does not change your final tax bill — it just changes when you receive your money. If you adjust your W-4 to reduce withholding, you take home more pay each month instead of waiting for a refund in April. This is usually better for your finances, because you can use that money throughout the year instead of lending it to the government. However, if you have trouble managing money or prefer to save through refunds, leaving withholding as is is a valid choice.
You can update your W-4 at any time by submitting a new form to your employer's payroll department. There is no penalty for changing it, and you can adjust it again if your situation changes — for example, if you get married, have a child, or take on a second job.
Use tax software or a tax preparer to catch what you miss
Tax software like TurboTax, H&R Block, and TaxAct walks you through questions about your income, deductions, and credits and flags items you may have missed. Many offer free versions if your income is below a certain threshold. The software calculates your refund and can file electronically, which is faster than mailing a paper return.
A tax preparer or CPA can review your full financial situation and find deductions and credits you might not know about. This is especially useful if you are self-employed, have investment income, own rental property, or have a complex family situation. The cost of a preparer is often worth it if they find deductions that reduce your tax bill by more than their fee.
If you cannot afford a preparer, the IRS partners with nonprofits to offer free tax preparation through the Volunteer Income Tax information (VITA) program. You can find a VITA site near you by entering your zip code at irs.gov/vita. VITA preparers are trained to find deductions and credits and file your return for free if your income is below a certain limit.
Understand what actually affects refund size
Your refund is the difference between the total tax you paid (through withholding and estimated payments) and the total tax you owe (after deductions and credits). To increase your refund, you can increase what you paid in, or decrease what you owe. Increasing what you paid in by adjusting your W-4 does not make sense — that just means you overpaid more. The real way to increase your refund is to decrease what you owe by finding deductions and credits.
Some people think they can increase their refund by claiming deductions they do not actually have or by inflating numbers. This is tax fraud, and the IRS catches it through matching your return to documents like W-2s, 1099s, and mortgage statements. The penalty is much larger than any refund you might gain, plus interest and possible criminal charges. The only legitimate way to increase your refund is to claim deductions and credits you actually may have access to for.
Frequently Asked Questions
What if I am self-employed — how do I get a bigger refund?
Self-employed people can deduct all ordinary business expenses: supplies, equipment, vehicle mileage, a portion of home office rent or mortgage, health insurance premiums, and retirement plan contributions. Keep receipts and records for everything. You may also owe quarterly estimated tax payments instead of having tax withheld, so adjust those payments to avoid owing money at tax time. A tax preparer familiar with self-employment can help you find deductions you might miss.
Can I claim a dependent if they live with me but are not related to me?
Yes, if they meet the IRS definition of a dependent. They must live with you for the entire year, be a U.S. citizen or resident alien, have a Social Security number, and have a relationship to you that does not violate state law. They cannot be a may have access to child of another taxpayer, and their income must be below a certain limit. The dependent does not have to be related to you by blood or marriage.
If I get married mid-year, how does that affect my refund?
You can file as married filing jointly or married filing separately for the year you marry, even if you married on December 31. Married filing jointly usually results in a smaller combined tax bill than filing separately, so it is usually the better choice. You will need both Social Security numbers and both spouses' income information to file. If you married late in the year, you may want to adjust your withholding for the following year to account for the change in filing status.
What happens if I claim a credit I do not actually may have access to for?
The IRS will disallow the credit, and you will owe the tax plus interest and possibly a penalty. If the error was unintentional, the penalty is usually smaller than if it was intentional. Always keep documentation for any credit you claim — receipts for education expenses, proof of childcare costs, or records showing your income. If you are unsure whether you may have access to, ask a tax preparer or call the IRS helpline before filing.
Is there a limit to how much I can deduct for charitable donations?
Yes. You can deduct up to 50% of your adjusted gross income for cash donations to may have access to charities, and lower percentages for donations of property or to certain types of charities. You can carry forward unused deductions to future years. You must itemize to claim charitable deductions, and you must have a receipt or written acknowledgment from the charity for donations of $250 or more.
