As of January 1, 2020 there will be 37 Marketplace states plus the District of Columbia, 5 states that do not collect sales tax and 8 states that are non-Marketplace. Our expectation is that many of the non-Marketplace states will pass laws in the next year.
Note that we have spent a lot of time and effort on both the technology as well as getting tax and legal advice to guide our implementation. There may still be local laws, statutes or rulings that we may not be aware of. If you think our system is miscalculating, then please provide us direct links to that appropriate state ruling and we will consult with our lawyers. Note, there will be no exceptions to how we implement this system as we must follow the legal and tax advice we have received from our advisors.
