Certified services providers; allowances for sellers and

certified service providers under the agreement; relief for failure to collect tax
Sec. 10. (a) A certified service provider is the agent of a seller, with whom the certified service provider has contracted, for the collection and remittance of sales and use taxes. As the seller's agent, the certified service provider is liable for sales and use tax due each member state on all sales transactions it processes for the seller except as set out in this section. A seller that contracts with a certified service provider is not liable to the state for sales or use tax due on transactions processed by the certified service provider unless the seller misrepresented the type of items it sells or committed fraud. In the absence of probable cause to believe that the seller has committed fraud or made a material misrepresentation, the seller is not subject to audit on the transactions processed by the certified service provider.
A seller is subject to audit for transactions not processed by the certified service provider.
The member states acting jointly may perform a system check of the seller and review the seller's procedures to determine if the certified service provider's system is functioning properly and the extent to which the seller's transactions are being processed by the certified service provider.

(b) A person that provides a certified automated system is responsible for the proper functioning of that system and is liable to the state for underpayments of tax attributable to errors in the functioning of the certified automated system. A seller that uses a certified automated system remains responsible and is liable to the state for reporting and remitting tax.

(c) A seller that has a proprietary system for determining the amount of tax due on transactions and has signed an agreement establishing a performance standard for that system is liable for the failure of the system to meet the performance standard.

(d) A certified service provider or a seller that obtains a certification or taxability matrix from the department is not liable for sales or use tax collection errors that result from reliance on the department's certification or taxability matrix. If the department determines that an item or transaction is incorrectly classified as to the taxability of the item or transaction, the department shall notify the certified service provider or the seller of the incorrect classification. The certified service provider or the seller must revise the incorrect classification within ten (10) days after receiving notice of the determination from the department. If the classification error is not corrected within ten (10) days after receiving the department's notice, the certified service provider or the seller is liable for failure to collect the correct amount of sales or use tax due and owing.

(e) If at least thirty (30) days are not provided between the enactment of a statute changing the rate set forth in IC 6-2.5-2-2 and the effective date of the rate change, the department shall relieve the seller of liability for failing to collect tax at the new rate if:
