Amazon joins Walmart in push for online sales tax not out of some newfound concern for "marketplace fairness," but because Amazon's business model is changing in such a way that now Amazon stands to benefit from this tax.
In order to provide faster shipping, Amazon is building warehouses throughout the country. These warehouses constitute a "physical presence," which requires them to collect sales taxes, in any event. So, if Amazon is going to have to collect sales taxes under the existing "physical presence" doctrine, it may as well try to expand online sales taxes to whack its smaller competitors who don't have a 50-state network of giant warehouses.
Sigh!
I live in NY where Amazon already collects sales tax so it doesn't really matter to me.
(I say this as a fan of Amazon -- I use them all the time and will continue to do so, but this is a purely shrewd corporate move and shouldn't be confused with making things fair).
Since Amazon has been growing its SaaS business for some time now one had to expect they were eventually going to want to make operating shopping cart checkout by yourself as tricky as possible. They might start lobbying municipalities to pile on the complications now that they're on the "right" side of this dispute.
This was always a red herring. Vertex (and presumably others, although I've only worked with Vertex) already maintains this database, and will help any company calculate taxes for a reasonable fee. Corporations with far lower revenues than Amazon have been taxing in many jurisdictions for decades.
I can't blame Amazon though, just looking out for themselves which is the same as the rest of us do.
I can't blame the lobbyists either, they're just looking out for themselves the same as the rest of us do.
I can blame the legislators. They're the ones with a monopoly on force wielded against us for their own gain.
I can blame the electorate. They're the ones granting the power and the legitimacy to the force wielded against us.
As much as it sucks, money is power.
