Estimated Tax: Due Dates of Payments for Short-Period Returns


If a return is filed for a short period of less than 12 months, the estimated tax payments are due as follows:

(1)

If the period covered is less than four months, only one payment is required. It is equal to 100 percent of the estimated tax and is payable on the due date of the return.

(2)

If the period covered is four months or longer but less than six months, two payments are required. One-half of the estimated tax is due on the 15th day of the fourth month. The balance is due on or before the due date of the tax return, not including extensions.

(3)

If the period covered is six months or longer but less than nine months, three payments are required. One-third of the estimated tax is due on the 15th day of the fourth month, one-third on the 15th day of the sixth month and the balance on or before the due date of the tax return, not including extensions.

(4)

If the period covered is nine months or longer, but less than twelve months, four payments are required. One-fourth of the estimated tax is due on the 15th day of the fourth month, one-fourth on the 15th day of the sixth month, one-fourth on the 15th day of the ninth month, and the balance on or before the due date of the tax return, not including extensions.
