Fla. Admin. Code R. 12B-11.006
(1) Tax due on transactions:
(2) (a) Except as provided in rule Chapter 12-24, F.A.C., the payment and the Solid Waste and Surcharge Return (Form DR-15SW) must be delivered to the Department or be postmarked to avoid penalty and interest for late filing as follows:
1. On or before the 20th day of the month following the month in which the consideration is received, if the accounting records are maintained on the basis of cash receipts; or
2. On or before the 20th day of the month following the month in which the account receivable is posted, if the accounting records are maintained on the accrual basis.
3. If the 20th day falls on a Saturday, Sunday, or legal holiday, payments accompanied by returns will be accepted as timely if postmarked or delivered to the Department on the next succeeding day which is not a Saturday, Sunday, or legal holiday. For the purpose of this rule, a legal holiday means a holiday that is observed by federal or state agencies as a legal holiday, as this term is defined in Chapter 683, F.S., and s. 7503, Internal Revenue Code of 1986, as amended. A “legal holiday” pursuant to s. 7503 of the Internal Revenue Code of 1986, as amended, means a legal holiday in the District of Columbia or a statewide legal holiday at a location outside of the District of Columbia but within an internal revenue district.
(b) Electronic filing of payments and returns for reporting tax must be submitted to the Department, as provided in rule Chapter 12-24, F.A.C., when:
1. Payment of the tax is required to be made by electronic means;
2. Any return for reporting tax is required to be submitted by electronic means; or
3. No tax is due with a return for reporting taxes.
