For US federal tax this year, I mistakenly paid more to IRS than the amount I owe. I don't have a way to change the payment.
Is it possible to ask for a refund or credit next year?
Edit: I am owing say 2000$ this year. But I did some miscalculations and sent them 3000$ via bank. There is no way to revert this 3000$ payment now. But the tax file that I have sent is corrected. And it will show I owe 2000$. So, how I will get the extra 1000$?
As long as you submitted the payment correctly (marking it for the year 2022) it will be correctly applied to your account and you will have a positive balance.
If you haven't submitted your return yet, the payment should go to line 26 and the math will change to reflect the $1000 refund.
If you already submitted it, you now need to file a form 1040X showing amount taxes paid to correctly reflect the $3000 you paid, and you will have $1000 listed as refund due. You can then select what to do with it - receive it as a refund or apply to the next year.
You only need to file the form 1040X itself, since the amount you're adding goes on line 16 of that form and no number on the original return changed.
Summarizing the discussion in the comments:
You actually marked the $3000 payment as an estimated payment and marked it for the year 2023. That means that as applied, it should go to the line 26 of the return you'll be filing next April, and not the one you're filing now. You still owe the $2000 for the year 2022.
You may try calling the IRS at 800-829-1040 and asking them to reapply the $3000 from 2023 to 2022.
Welcome to the world of "accrual". Most people think "well if I send someone money, that's that. It's their money now". The IRS (and large corporations) think "If you send money it's still your money until some form or invoice happens to make it theirs".
So if you sent $1000 to the gas company that's your $1000 credit balance, and you can ask for it back. After a month and you have a $100 gas bill, they deduct the $100 and now you have $900 on credit and you can ask for it back. Etc.
So when you send money to the IRS, that goes into YOUR account at the IRS for that tax year. It's still your money up until you do a separate thing called "filing your taxes". Or alternately you can do nothing for 3 years and the money just becomes theirs.
So if you have not "filed your taxes", do so. The end of the form will show you owing a refund, and the IRS will send your refund.
If you already filed your taxes, this should have happened automagically. However if it didn't because you filed your taxes incorrectly, you can re-do your taxes and then file an amended 1040X, and IRS will issue a refund once they process that. However being a specialty thing, this is a lot slower and can take up to 6 months.
Some people simply let the IRS take their withholding, and knowing they're owed a small refund don't bother to file their taxes at all (and let the IRS keep it). Nothing wrong with that if that's your cup of tea... but if you now change your mind, guess what? There is no penalty for filing taxes late if the IRS owes you money. Not only that, once you have your "tax filing chops" down, you can go back 3 years and collect refund on 2020 or 2021 taxes (to get 2019 you'd have to file with a postmark of today April 17 2023).
