It is my understanding that dealers at coin shows are required to collect sales tax for the state the show is in, regardless of whether or not the dealer is located in that state. However, I could be incorrect (and the laws vary by state), as I don't recall seeing dealers charge sales tax for bullion purchases at coin shows.
Be aware that this information is accurate to the best of my knowledge. However, not being a lawyer, and not having seen the laws, I can't guarantee the accuracy of this information (if you are a dealer, you have to get information from your state).
| State | Rule |
|---|---|
| California | Tax on all bullion purchases under $1,000 (CA gold not taxed) |
| Florida | Tax on all bullion purchases under $500 |
| Massachusetts | Tax on all bullion purchases under $1,000 |
| New York | Tax on all bullion purchases under $1,000 |
| Texas | Tax on all bullion purchases under $1,000 |
