You would only have to do this if your sales are over $1 million. So probably not much of a problem for pen sellers (especially me!).
Wouldn't mind seeing the limit raised to 2 or 3 million. Hopefully they will index the amount for inflation as well. The states would be required (at this point - since the legislation can always get changed) to have electronic payment systems to make the process easier.
I can see this as causing a
lot of heartburn to small internet businesses and being a administrative nightmare to a lot of us.
It will really cause problems for businesses who 'border' on the edge of $1,000,000 sales.
It is particularily bad for those of us who live in one of the 'no sales tax' states like Delaware. We would have force on us - collecting sales tax for other states but not the state our business is in.
Amazon favors it because they've found a way to make money off it. They charge a fee for collecting the tax for businesses who sell through Amazon.
Ebay will no doubt start doing something similar to people who sell on eBay. There is no doubt in my mind that most of the US people are opposed to this - their costs will go up.
Those who favor this (as near as I can tell that would only be politicians wanting to get more of your money) are trying to sell it as a way to help "level the playing field" for
small box stores but I have not been able to figure out how they will benefit at all - it isn't going to increase traffic to them a bit. Small box stores are not losing business to the internet - many of them already have internet sales themselves or sell products not condusive to internet sales.
