Quarterly Tax Payments

Quarterly Tax Payments are estimated tax payments made prior to when taxes are due. They are typically done quarterly throughout the year.

First quarter: January 1 to March 31
Second quarter: April 1 to May 31
Third quarter: June 1 to August 31
Fourth quarter: September 1 to December 31

These estimated taxes help freelancers, whose taxes are not withheld from their paychecks, from getting a nasty tax surprise at the end of the year.
