The IRS requires you t pay estimated taxes four times a year (unless you choose to pay up front for the entire year).

If you haven't paid your estimated taxes

First, the bad news: The IRS will charge a daily penalty that starts on the day that your estimated taxes were due, and ends when they're paid in full.

Now, the good news: The penalty is quite low, only about six to eight percent. For example, let's say you owe $100 in taxes, but haven't paid it. You would only owe about $8 at the end of the year.

Here's the payment schedule for 2017:
 
  • Q1 income received from January 1 to March 31: Estimated tax is due on April 18, 2017.
  • Q2 income received from April 1 to May 31: Estimated tax is due on June 15, 2017.
  • Q3 income received from June 1 to August 31: Estimated tax is due on September 15, 2017.
  • Q4 income received from September 1 to December 31: Estimated tax is due on January 16, 2018.


How due dates work?

The due date is usually on the 15th of every third month. If the 15th falls on a weekend or a federal holiday, the due date is the next business day. Remember, though: The due date for all taxpayers is April 15. You need to make sure that you've paid all your taxes for the previous year by this date.

To see if you owe any penalties or to request a waiver, check out the IRS page   Form 2210, Underpayment of Estimated Tax.
