Soon this law will require online retailers to collect sales tax, but deciding the correct tax rate for each purchaser and item is difficult.
Do marketplaces like Amazon or payment processors like Stripe handle this for you?
Is there an business opportunity to provide this type of service? How cheaply could it be accomplished?
Can I use an uncertified provider?
Can I create my own and compete with the certified providers?
How difficult is to become "certified"?
Do you have any sources on how this process works?
US sales tax is a pain in the ass, however, largely because you end up with (after state, county and city tax) percentages like 4.568398%, and you end up in rounding hell, particularly if you sell items which cost $0.05.
Either way, it's moot. It'll never make it into law, house republicans will block it.
Each product is categorised into one of these "product tax types", once. The PTTs map to differently ID'd bands of taxation in each state, county, city.
It's a lot of data, but it's out there, for the most part.
So yeah, it is just a config flag.
That's the obvious answer, but its misleading. Its true that it will be at least 90 days (and maybe as much 180) before any states start collecting taxes. States that are members of the existing "Streamlined Sales and Use Tax Agreement" meets the basic requirements from day one, but no state can begin collecting taxes until the first calendar quarter beginning 90 days after the enactment of the Act.
But there are already several (including Intuit) Certified Software Providers for the states that are members of the Streamlined Sales and Use Tax Agreement, so anyone seeing this as a "business opportunity" is going to be jumping into a field where there are already big players.
