If you have mailed a check to the IRS in the last several months and it hasn't cleared the bank, DON'T CANCEL THE PAYMENT OR SEND IN ANOTHER CHECK. The IRS is still behind in processing the mail that has piled up due to COVID-10. Included in the backlog are 2021 tax returns, estimated tax payments for 2021 or other correspondence sent in by taxpayers with paper checks. There is no need to worry about penalties if you sent the payment in on time. IRS credits payments to accounts based on the envelope's postmark date, not the date the payment is processed.
