Bullzogby. This NEVER was the case with mailorder catalog sales.
Your state sales tax could vary even within the state depending on which county the sale took place in. You didn't have to "make up the difference" to your home county.
Also sales tax was not due on Income Tax day. It can be quartely, monthly, or annually depending on how many sales you make in a year. My annual return followed the calendar year.
This guy is giving tax advice???

In Wisconsin, we have what is called a "Sales and Use Tax". It is our law that if you purchase anything that has not had the sales tax collected on it (internet purchases for example) you are supposed to report it and pay the tax.
