Answer: The CSP is responsible for determining the taxability and for calculating the proper sales or use tax that applies to products or services you sell in any of the Streamlined sales tax states.
The CSP is not responsible for your obligation to remit tax on your purchases. You may discuss use tax reporting with your CSP. If you do not report use tax through the CSP you will need to file a separate use tax return directly with the state.
If the CSP does not report other taxes you may currently report on your state sales tax return, such as lodging or tourism tax. Talk to your CSP to determine if you need to report those taxes directly to the state.
Please contact the state in which tax is due to determine how to report any tax not reported through the CSP.
