The short answer: almost never
The IRS does not let you apply a refund from one year to next year's tax bill automatically. If you want your 2024 refund to pay toward your 2025 taxes, you have to ask for it explicitly when you file — and even then, the IRS will only hold the money if you make that request in writing before the refund is issued. Most people should take the refund as cash instead.
The reason this matters: if you do nothing, your refund goes to your bank account or arrives as a check. You keep it. If you want it to go toward next year instead, you must file Form 8888 (Allocation of Estimated Tax Payments) with your current-year return and specify the dollar amount. The IRS will then treat that money as a payment toward your next year's tax liability rather than sending it to you.
Key Takeaways
- You must request the refund-to-next-year transfer on Form 8888 before your current return is processed — you cannot change your mind after the refund is issued.
- The IRS holds the money as a credit against your next year's taxes, but you do not earn interest on it and cannot access it if your circumstances change.
- This strategy only makes sense if you know you will owe taxes next year and want to avoid a large payment or penalty.
- If you are unsure whether you will owe next year, taking the refund now and saving it yourself gives you more control and flexibility.
- The money is safer in your own account than held by the IRS, where it sits without interest and cannot be withdrawn if you need it.
When applying a refund to next year might make sense
The only real reason to do this is if you are certain you will owe federal taxes next year and you want to reduce that bill before April. This happens most often to self-employed people, gig workers, or contractors who know their income will be high and their withholding will be low. If you expect to owe $3,000 or more in April, applying this year's $2,000 refund to next year cuts your payment obligation in half.
It also avoids the need to make estimated quarterly tax payments if the refund credit is large enough. If you owe $5,000 next year but you apply a $4,000 refund now, you only have to pay $1,000 in April instead of spreading payments across four quarters.
Even in these cases, however, the advantage is small. You are not earning interest on the money while the IRS holds it, and if your income drops or your withholding changes, you cannot get the money back — it stays locked as a credit against taxes you may not owe.
Why most people should take the refund instead
Taking your refund as cash gives you control. You can deposit it in your own savings account, where you can access it if an emergency happens. You can spend it if your circumstances change. You can earn interest on it (though most savings accounts pay very little). Most importantly, you are not betting on what your taxes will look like next year.
Your income, withholding, filing status, dependents, or deductions might all change between now and next April. If you lock $2,000 into next year's taxes and then your income drops, you will have overpaid and have to wait for a refund. If you take the money now and save it yourself, you have the flexibility to adjust.
The IRS also does not pay interest on refunds you apply to future years. If you held that money in a savings account for twelve months, you would earn at least a small amount. Leaving it with the IRS earns you nothing.
How to apply a refund to next year if you decide to do it
You must file Form 8888 with your current-year tax return. This form lets you split your refund into multiple destinations — some to your bank account, some to savings bonds, and some to next year's taxes. You specify the dollar amount you want applied to next year in the third section of the form.
The key constraint: you must include Form 8888 with your return when you file. You cannot file your return, receive your refund, and then change your mind. Once the IRS processes your return without Form 8888, the refund is yours to keep. If you filed electronically and already received your refund, it is too late.
If you file on paper, make sure Form 8888 is attached to the front of your return. If you file electronically through tax software, the software will ask whether you want to split your refund and will include the form automatically if you say yes.
What happens to the money after you apply it
The IRS treats the amount you apply as a payment toward your next year's tax liability. When you file your 2025 return in 2026, the IRS will subtract that credit from the taxes you owe. If you owe $3,000 and you applied $2,000 from this year, you will only owe $1,000.
If you end up not owing anything next year — because your income was lower or your withholding was higher — the credit becomes a refund. The IRS will send you the overpayment, but this takes the same amount of time as a normal refund (typically two to three weeks after you file, though it can take longer if the IRS has questions about your return).
You do not earn interest on the credit while the IRS holds it. You also cannot withdraw it early if you need the money. It sits as a credit until you file next year's return.
The risk of locking money away with the IRS
Once you apply a refund to next year, you cannot get it back. If you lose your job, face a medical emergency, or your car breaks down, that money is not available to you. It stays with the IRS as a credit against taxes you have not filed yet.
This is different from keeping the refund yourself. If you deposit $2,000 in your savings account and then face an emergency, you can withdraw it. If the IRS holds $2,000 as a credit, you cannot touch it until you file next year's return — and even then, only if you actually owe taxes.
The IRS also does not may provide that the credit will be applied correctly. Errors happen. If the IRS loses track of your credit or applies it to the wrong year, you will have to contact them to fix it, which can take weeks or months.
Alternatives if you know you will owe taxes next year
Instead of applying your refund to next year, consider making estimated quarterly tax payments if you are self-employed or have income without withholding. These payments are due in April, June, September, and January. You can adjust them based on your actual income, which gives you more flexibility than locking a refund into next year.
Another option: take your refund now and set it aside in a separate savings account labeled "taxes." This way, the money is there when you need it in April, but you can still access it if an emergency happens. You maintain control and can adjust your plan if your income changes.
If you are worried about owing a large amount next year, you can also increase your withholding on your W-4 form now. This reduces your take-home pay but ensures more money is withheld throughout the year, which means a smaller bill (or a larger refund) next April.
Frequently Asked Questions
Can I change my mind after I file if I applied my refund to next year?
No. Once the IRS processes your return with Form 8888, the decision is final. You cannot call the IRS and ask them to send you the money instead. If you filed electronically and have not yet received the refund, contact the IRS immediately to see if they can stop the credit before it is applied, but this is not may provide to work.
What if I apply my refund to next year and then I do not owe anything?
The credit becomes a refund. The IRS will send you the overpayment when you file your next return, but this takes the normal refund processing time — usually two to three weeks, sometimes longer. You will not earn interest on the credit while you wait.
Does applying my refund to next year reduce my tax bill or just the payment I owe?
It reduces the payment you owe in April. Your actual tax liability is calculated based on your income and deductions. The credit is simply a payment toward that liability, so it lowers what you have to pay but does not change your tax rate or the amount of tax you technically owe.
Is there any advantage to letting the IRS hold my money instead of keeping it myself?
No. The IRS does not pay interest, you cannot access the money if you need it, and you lose flexibility if your circumstances change. Keeping the refund yourself and saving it gives you all the same benefit with more control.
What if I file my taxes late — does that affect the credit?
No. As long as Form 8888 was included with your return when you filed, the credit will be applied to next year's taxes whenever you file them. The timing of when you file does not change how the credit works.
