The Indiana Department of Revenue utilizes Form SF-900, formally known as the Consolidated Special Fuel Monthly Tax Return (State Form 49877), as the primary document for reporting special fuel tax liabilities. This consolidated return is designed for a variety of license holders, including suppliers, permissive suppliers, importers, exporters, blenders, and dyed fuel users, allowing them to report their monthly activities on a single cohesive form. The document serves a dual purpose: it calculates the special fuel tax due based on receipts and disbursements, and it also computes the oil inspection fee. Filing this form is a mandatory requirement for every Indiana licensed entity dealing in special fuel, and it must be submitted monthly along with corresponding schedules, regardless of whether any tax is actually owed for that period. The form ensures that the state can accurately track fuel movements, verify tax payments, and assess any necessary penalties or interest for late submissions.
How To File
The return is due on the 20th day of the month following the liability period (for example, January’s return is due February 20th). Filing can be completed electronically via the DOR’s e-services portal, INTIME. Payments for suppliers, permissive suppliers, blenders, and dyed fuel users must be made by the due date. Specifically, suppliers and permissive suppliers are required to remit payments via Electronic Funds Transfer (EFT).
