After you file

Will I receive a form from the IRS acknowledging the estimated tax I paid so I can add it to taxes paid on my 2021 Form 1040?  Is there a separate line for this on the 1040 or perhaps a Schedule?  I never did this sort of thing before.


If you use the IRS website to pay estimated taxes you will receive a confirmation number for the payment.  The IRS does not send you any type of form for the payment you made.

You report the estimated tax payments made in 2021 on the 2021 tax return you file next year.
