No, you don't. There are certain conditions which the states have to meet before they can start requiring collection. One of which is to certify one or more service providers which can be used to determine the appropriate sales tax to be collected. Currently 24 states have already certified 6 service providers including one free one. It is expected that most states will certify one or more of the existing 6 providers. If you use a certified service provider to determine the tax to be collected and the service provider makes an error you are indemnified from liability. Many e-commerce platforms already have integration with these providers. Besides determining the tax rate the providers can provide reporting regarding taxes collected and automatically file your tax returns to the states.
