Sales tax monthly return Form 850 due (2/20)

The sales tax report is Form 850. If you file monthly, it's due the 20th of the month following the tax period (e.g. October's return is due November 20). If you file quarterly, it's due the 20th of the month following the end of a quarter. For example, the 1st quarter report is due April 20.

(Jan. 20, April 20, July 20, and Oct. 20 fall on a weekend and so it's due the next business day.)
