Quarterly Estimated Tax Payments - Reminder
If you are making quarterly estimated tax payments to the IRS, the due date for the September 1st - December 31st quarter of the year is January 15th.
For payments made using IRS Direct Pay, you can make payments until 8PM EST, and for payments using a credit or debit card, payments can be made up to midnight on the due date.
If the due date for making an estimated tax payment falls on a Saturday, Sunday, or legal holiday, the payment will be considered on time if you make it on the next day that's not a Saturday, Sunday, or legal holiday.
