Sales & Use Tax Filing Guide

    Everything small businesses need to know about collecting, reporting, and filing sales and use taxes.

    Don't skip this!

    Many small business owners don't know they're required to collect and remit sales tax. Failure to file can result in penalties, interest, and even business license revocation.

    What is Sales Tax?

    Sales tax is a consumption tax charged on the sale of goods and certain services. As a business owner, you collect this tax from customers and remit it to your state (and sometimes local) government.

    What is Use Tax?

    Use tax applies when you purchase taxable items for your business and the seller didn't charge sales tax (common with online purchases from out-of-state sellers). You owe use tax at the same rate as your local sales tax.
