Your quarterly estimated tax payment is due soon.
Third Quarter 2017 taxes due by September 15, 2017.
Estimated tax is used to pay income tax and self-employment tax, as well as other taxes and amounts reported on your tax return. If you do not pay enough through withholding or estimated tax payments, you may be charged a penalty. If you do not pay enough by the due date of each payment period you may be charged a penalty even if you are due a refund when you file your tax return.
When To Pay Estimated Tax
For estimated tax purposes, the year is divided into four payment periods. Each period has a specific payment due date. If you do not pay enough tax by the due date of each of the payment periods, you may be charged a penalty even if you are due a refund when you file your income tax return.
If a payment is mailed, the date of the U.S. postmark is considered the date of payment. The payment periods and due dates for estimated tax payments are shown next. For exceptions to the dates listed, see Saturday, Sunday, holiday rule .
