When we first started discussing AB 178 (the "Amazon tax" bill in the California Assembly), we all recognized that it was inspired by the New York law.
However, I now think that it is
critically important to point out that AB 178 (as drafted) is much, much broader than the New York law. I
expect that it will be
amended to conform more closely with the New York law, but right now it is
not modeled on the New York law, it is merely "inspired by" the New York law.
Another important

several commentators have noted that Amazon's lawsuit in New York was dismissed by the New York
Supreme Court, as if that is the final decision. In fact, in New York, the "Supreme Court" is what the regular trial courts are called -- it is
not an appellate court, and I certainly assume that Amazon is appealing the ruling.
This is critically important because some folks seem to believe that the New York law has already been considered and "approved" by New York appellate courts, which has not happened. In addition, it's critically important to note that the law which the New York
trial court upheld is
very, very different from the law now proposed in California.
If legislators believe that (1) this bill is the same as New York's, and (2) the New York law has already been upheld by NY appellate courts,
then they are much less likely to consider amending it.
In addition, if other folks believe that the California law merely "mirrors" the New York law, they may be shocked to later discover that it is much broader, and would effectively force
all merchants (selling more than $10,000 in products to Californians) to collect sales tax.
