There is no legal minimum refund amount

The IRS does not set a floor on how small your refund can be. If you overpaid taxes by $1, the IRS will refund $1. If you overpaid by 47 cents, you will receive 47 cents. There is no threshold below which the government keeps your money.

That said, the practical question most people ask is different: at what point does a refund become too small to be worth the effort of filing? That depends on your situation and how you file.

Key Takeaways

  • The IRS has no minimum refund amount — you can receive a refund of any size, including less than $1.
  • If you are not required to file a tax return, a small refund is not a reason to file unless you want to claim the Earned Income Tax Credit or other refundable credits.
  • Filing costs nothing if you use free software or a free clinic, so the decision depends on whether you have time rather than money.
  • The IRS processes refunds of all sizes the same way, whether by direct deposit or check, with no difference in speed based on amount.

When a small refund might not be worth filing for

If you are not required to file a return — meaning your income fell below the filing threshold for your age and filing status — then a small refund is genuinely optional. You can choose not to file and keep the money the IRS would have refunded.

The filing threshold changes each year and depends on your age, filing status, and type of income. For example, in 2024, a single person under 65 with only wage income does not have to file unless their income exceeded $14,600. If you earned $14,200 and had taxes withheld, you could file to get that refund, or you could skip it.

The exception is if you are may have access to to a refundable credit — most commonly the Earned Income Tax Credit (EITC) or the Child Tax Credit. These credits can result in a refund even if you owe no tax. In that case, filing is worth doing even if your refund is small, because you are claiming money you are may have access to to, not just getting back what you overpaid.

How filing method affects whether a small refund matters

If you file using free tax software or a free tax clinic, the cost to you is zero. In that situation, a small refund is worth filing for straightforward because there is no downside — you spend time but no money.

If you paid a tax preparer to file your return, the math changes. A $50 refund costs you money if you paid $75 to have the return prepared. In that case, you would have been better off not filing. However, most tax preparers will not charge you to file if your refund is small, or they will charge a flat fee that makes sense only if your refund is larger.

How the IRS processes refunds of different sizes

The IRS processes a $15 refund the same way it processes a $1,500 refund. There is no separate queue for small refunds, no delay, and no difference in how long it takes to reach your account.

If you choose direct deposit, the refund goes to your bank account in the timeframe the IRS publishes — typically 21 days from when they accept your return, though it can be faster. If you choose a paper check, it takes longer, but again, the amount does not change the timeline.

The IRS does not round down or hold small refunds. If your calculation shows $0.67, that is what you receive.

Why people think there is a minimum

The confusion often comes from two sources. First, some employers or payroll systems have their own rules about refunding small amounts — a company might decide not to process a reimbursement under $1. The IRS itself has no such rule.

Second, some tax software or tax preparers may discourage you from filing if the refund is very small, not because it is illegal, but because they want to manage customer expectations or because their fee structure makes it uneconomical for them.

What to do if your refund is smaller than you expected

If you calculated a larger refund but the actual amount is small, check your return for common reasons: additional income you forgot to report, credits you do not actually may have access to for, or a calculation error. You can review your return before you file it in most tax software.

If you already filed and the refund is smaller than expected, you can file an amended return (Form 1040-X) if you believe there was an error. However, if the return was correct, the small refund is final.

Frequently Asked Questions

Can the IRS keep my refund if it is under a certain amount?

No. The IRS will refund any amount, no matter how small. There is no minimum threshold.

Will I get my refund faster if it is a large amount?

No. The IRS processes all refunds on the same timeline. A $10 refund and a $1,000 refund take the same number of days to arrive if you use the same method (direct deposit or check).

Is it worth filing if my refund is only $20?

If filing is free and you are not required to file, it depends on whether you want that $20. If you used free software or a free clinic, there is no cost to you, so filing makes sense. If you paid someone to prepare your return, the cost might outweigh the refund.

What if I owe a small amount instead of getting a refund?

You still have to file and pay what you owe, even if it is $5. The IRS does not waive small amounts owed. However, you can request a payment plan if paying in full is difficult.

Does a small refund affect my credit score?

No. A tax refund has nothing to do with credit. It does not appear on your credit report and does not change your credit score.
