The payment due dates for Individual Estimated Income Taxes are the same as for the IRS. If a due date falls on a weekend or legal holiday, the due date is automatically extended to the next business day. The first quarterly payment is due April 15th with the annual return declaration. The remaining payments are due June 15th, September 15th and January 15th of the following year.
