The biggest refunds come from claiming deductions and credits you actually may have access to for, not from tricks or timing

A larger tax refund is not about outsmarting the system — it is about making sure the IRS has the right information about your income, expenses, and life circumstances. The refund itself is money you overpaid during the year; the goal is to reduce what you owe so less is refunded, or to claim credits and deductions that lower your tax bill. Most people leave money on the table by missing deductions they may have access to for, filing incompletely, or not knowing which credits exist for their situation.

The IRS does not volunteer information about credits you might claim. You have to know they exist, understand whether you meet the requirements, and report them on your return. The same is true for deductions. This guide walks through the main categories where people find larger refunds, what documents you need to claim them, and how to avoid common mistakes that delay or reduce your refund.

Key Takeaways

  • Child tax credits, education credits, and earned income tax credits can each reduce your tax bill by hundreds or thousands of dollars, but only if you report them on your return.
  • Deductions for student loan interest, mortgage interest, charitable donations, and medical expenses reduce your taxable income, but you must have receipts or statements to back them up.
  • Filing status matters: married filing jointly usually produces a larger refund than married filing separately, and head of household status can lower your tax rate if you meet the requirements.
  • The IRS matches information from employers, banks, and other sources to your return; mismatches delay refunds, so double-check that names, Social Security numbers, and income figures are exact.
  • Claiming dependents you do not have, inflating deductions, or omitting income are red flags that trigger audits and can result in penalties larger than any refund you gain.

Claim child and dependent credits if you support children or other relatives

The Child Tax Credit is worth up to $2,000 per child under age 17 at the end of the tax year. You must be the child's parent, grandparent, or legal guardian, and the child must have a valid Social Security number. The child's relationship to you, their age, and your income all determine whether you can claim the full amount or a reduced amount.

The Child and Dependent Care Credit applies if you paid someone to care for a child under age 13 or a disabled dependent while you worked or looked for work. You can claim 20 to 35 percent of what you paid, depending on your income. You need the name, address, and tax ID of the person or facility you paid — if you cannot provide it, you cannot claim the credit.

The Credit for Other Dependents is worth $500 per dependent who does not may have access to for the Child Tax Credit — for example, a parent you support, a grandchild over age 16, or an adult child with a disability. The dependent must live with you for the entire year, be a U.S. citizen or resident alien, and have a Social Security number.

Look for education credits and deductions tied to tuition and student loans

The American Opportunity Tax Credit is worth up to $2,500 per student per year for the first four years of college. You claim it for tuition, fees, and course materials — not room and board. Your income must be below a certain threshold, which varies by filing status. You need Form 1098-T from the school, which reports what you paid.

The Lifetime Learning Credit is worth up to $2,000 per return (not per student) and covers tuition and fees for any level of education or training, including graduate school and professional certifications. You cannot claim both the American Opportunity and Lifetime Learning credits for the same student in the same year, so you have to choose which one produces a larger refund.

The Student Loan Interest Deduction lets you deduct up to $2,500 of interest you paid on federal or private student loans. You do not have to itemize deductions to claim it. Your income must be below a threshold that phases out the deduction. You need a 1098-E form from your loan servicer, which shows how much interest you paid.

Claim the Earned Income Tax Credit if your income is below the limit

The Earned Income Tax Credit (EITC) is a refundable credit, meaning you can receive money back even if you owe no tax. The amount depends on your income, filing status, and whether you have children. For 2023, the maximum credit for someone with three or more children was $3,995; for someone with no children, it was $560. These amounts change each year.

You must have earned income from work — wages, self-employment income, or tips. Investment income, unemployment benefits, and Social Security do not count. If you are self-employed, you report your net profit from Schedule C. If you have children, they must have valid Social Security numbers and live with you for more than half the year.

Many people with low to moderate income do not claim the EITC because they do not know it exists or think they do not may have access to. The IRS has a tool on its website where you can enter your income and filing status to see whether you might be may be able to access. If you use a tax preparer or software, it will ask questions to determine whether you may have access to.

Itemize deductions if they exceed the standard deduction for your filing status

You can either take the standard deduction — a flat amount based on your filing status — or itemize deductions by listing specific expenses on Schedule A. You choose whichever is larger. For 2023, the standard deduction was $13,850 for single filers and $27,700 for married filing jointly; these amounts increase each year.

Common itemized deductions include mortgage interest, property taxes, state and local income taxes (capped at $10,000 total), charitable donations, and medical expenses that exceed 7.5 percent of your adjusted gross income. You need receipts, bank statements, or written acknowledgment from charities to back up what you claim. The IRS can ask you to prove any deduction, so keep documents for at least three years.

If your itemized deductions are close to the standard deduction, you might benefit from bunching — making large charitable donations or paying property taxes in one year instead of spreading them across two years. This strategy pushes your itemized deductions above the standard deduction in one year, allowing you to take the standard deduction in the other year and claim more total deductions over time.

Report all income, including side work and investment earnings

The IRS receives copies of W-2 forms from your employer, 1099 forms from clients or platforms where you do gig work, and 1099 forms from banks and investment accounts. If your return does not match what the IRS already knows, your refund is delayed while they investigate. If you omit income, you owe back taxes, interest, and penalties.

Self-employment income from a side business, freelance work, or gig platforms like DoorDash or Uber must be reported on Schedule C, even if you received no 1099 form. You deduct business expenses — supplies, equipment, mileage, home office — to arrive at your net profit. Keep receipts and a mileage log if you claim vehicle expenses.

Interest from savings accounts, dividends from stocks, and capital gains from selling investments are reported on Schedule B or Schedule D. Even small amounts must be included. If you have a lot of investment income, you may owe the Net Investment Income Tax, an additional 3.8 percent tax on certain types of investment income.

Choose the right filing status and claim dependents accurately

Your filing status — single, married filing jointly, married filing separately, head of household, or may have access to widow(er) — determines your tax rate and the deductions and credits you can claim. Head of household status applies if you are unmarried, pay more than half the household expenses, and have a may have access to dependent living with you. It produces a lower tax rate than single status.

Married couples usually get a larger refund filing jointly than separately, because the joint tax brackets are wider. However, if one spouse has a large amount of deductions or credits, filing separately might be better. You can file one way, then file an amended return if the other way produces a larger refund — but you must do this within three years of the original due date.

You can only claim someone as a dependent if they are a U.S. citizen, national, or resident alien; have a valid Social Security number; live with you for the entire year (with limited exceptions); and do not file their own return. If you claim someone who does not meet these requirements, the IRS will disallow the deduction and assess penalties. Do not guess — verify the requirements before you claim.

Double-check your return before submitting to avoid delays and errors

The most common reasons refunds are delayed are mismatched names or Social Security numbers, math errors, and missing information. Before you file, verify that your name, address, and Social Security number are exactly as they appear on your Social Security card. If you recently married or changed your name, update your Social Security record first.

If you have a dependent, make sure their name and Social Security number match their Social Security card. If the IRS receives a return with a dependent's number that does not match their records, they will reject the return or delay processing. The same applies to spouses — if your spouse's information does not match, the return is flagged.

If you file electronically, the software checks for math errors and missing required fields before you submit. If you file on paper, errors are caught during processing, which delays your refund. Review the return line by line: income figures from W-2s and 1099s, deductions you claimed, credits you reported, and the math. A small error can cost you hundreds of dollars or months of waiting.

Frequently Asked Questions

Can I claim a deduction for something I did not have a receipt for?

The IRS requires documentation for most deductions. For charitable donations over $250, you need a written acknowledgment from the charity. For medical expenses, mortgage interest, and property taxes, you need statements from the provider. For smaller donations or expenses, a bank statement or credit card statement showing the payment may be enough, but the IRS can ask for more detail. If you cannot produce documentation, you cannot claim the deduction.

What happens if I claim a credit I do not actually may have access to for?

The IRS will disallow the credit, reduce your refund, and may assess a penalty. If the error was unintentional, the penalty is usually 20 percent of the underpaid tax. If the IRS determines the error was fraudulent, the penalty can be 75 percent. You can avoid penalties by being honest about what you claim and keeping documentation to back it up.

Is it better to have more money withheld from my paycheck so I get a bigger refund?

A larger refund means you gave the government an interest-free loan all year. If you adjust your withholding so less is taken out, you have more money in your paycheck to spend or save. You can use the IRS withholding calculator on its website to estimate how much should be withheld based on your income, deductions, and credits. The goal is to owe little or nothing when you file, not to get a large refund.

Can I file my return before I receive all my tax documents?

You can file once you have your W-2 from your employer, but if you are waiting for a 1099 from a client or investment account, filing early means you might have to file an amended return later. The IRS has a important date of March 31 for employers to send W-2s and a important date of January 31 for most 1099s. If you file before you have all your documents, you risk omitting income and triggering an audit.
