In addition, review the instructions for determining the correct tax period end date (e.g., for quarterly returns, Forms 720, Forms 941, etc., March 31, June 30, September 30, December 31). Enter as the MM in the YYMM format as:

Quarter Format

2nd quarter June 30 30-06
3rd quarter September 30-09
4th quarter December 31-12
