Charging a client's credit card on 12/31/21, doesn't hit my bank until 1/3/22: In which year to count it as income?

[MarkWilliamsIsOnFire]

I own a psychotherapy business, and I use Square to handle my clients' credit card payments. I charged a client's card on 12/31/21 for a rather large amount, and it didn't get deposited into my bank account until 1/3/22. If I run a report in Square, it counts the income in 2021. But if I run a report in my money management software for my business bank account, it counts the income in 2022.

Which is it? Which year should it go in? When the client was charged? Or when the money appeared in my bank account?

Thanks in advance for the help!

The full text of the IRS regulation defining constructive receipt states as follows:

“Income although not actually reduced to a taxpayer's possession is constructively received by him in the taxable year during which it is credited to his account, set apart for him, or otherwise made available so that he may draw upon it at any time, or so that he could have drawn upon it during the taxable year if notice of intention to withdraw had been given. However, income is not constructively received if the taxpayer's control of its receipt is subject to substantial limitations or restrictions.

Square, Inc. is a financial services company, not a bank.
