Q3 estimated tax payments are due September 15, covering any income earned between June 1 and August 31. If you're required to pay estimated tax and you miss this deadline, or underpay, you can face a penalty even if you're due a refund when you file.

 

This episode of The Answer Room breaks down exactly who owes a Q3 payment, how to calculate the amount using Form 1040-ES, and how to pay and record it correctly in QuickBooks, so nothing gets flagged as overdue and nothing slips past September 15. Tune in below.
