(a) Model 1 or 2 sellers with business locations in this state shall submit their returns in a format required by the commissioner. Model 1 or 2 sellers that do not have business locations in this state may submit their returns in a format adopted by the member states to the Streamlined Sales and Use Tax Agreement; provided, however, that all of the returns shall be filed electronically.

(b) Notwithstanding any law to the contrary, the commissioner is authorized to require Model 1 or 2 sellers that submit returns in a format adopted by the member states to the Streamlined Sales and Use Tax Agreement to submit once a year an informational return as permitted by the member states to the Streamlined Sales and Use Tax Agreement.

(c) Notwithstanding the provisions of § 67-1-703 to the contrary, all remittances from Model 1 or 2 sellers shall be made electronically, using ACH Credit or ACH Debit processes. The commissioner is authorized to provide for an alternative method of making the payment in the event the electronic funds transfer process fails.

(d) Notwithstanding any law to the contrary, a seller that is registered using the central registration system provided by states that are members of the Streamlined Sales and Use Tax Agreement, does not have a legal requirement to register in this state, is not a Model 1 or 2 seller, and has not accumulated more than one thousand dollars ($1,000) in state and local sales and use taxes shall be permitted to file a sales and use tax return at any time within one (1) year of the month of initial registration and shall be permitted to file future returns on an annual basis in succeeding years. The returns shall be due the twentieth day of the month following the tax period covered by the return. A seller that has accumulated state and local sales and use tax funds in the amount of one thousand dollars ($1,000) shall file a return by the twentieth day of the month following the month in which the accumulated taxes reach or exceed one thousand dollars ($1,000). Nothing in this subsection (d) shall relieve a seller who collects state sales or use tax from its customers from liability for failure to pay over those funds to the commissioner on behalf of the state.
