Re: or...
Far easier? A flat rate tax of say 0.5% on all online sales (shipped/sold to/from) to the country. Amazon et al would pay far far more than currently, while smaller companies would barely notice it.
Also, eBay etc would have to pass it to their sellers, meaning all the tax dodger companies actually pay something despite pretending to be selling stuff out their attic!
It is so simple. What have I missed?
