Thanks to the WAC 458-20-248 code, there is no precious metal tax in the state of Washington. Established in 1985, this code states that anything that qualifies as a precious metal, including bullion, is exempt from taxation. This law is quite broad, but basically it covers any gold or silver that has been or can be used as currency in the United States or in any other country. This means that coins such as the US Eagle, the silver and gold Maple Leaf and other popular bullion coins will not carry a tax.
This does not, however, include numismatic coins and other precious metal collectibles. In such cases the state’s sales tax will apply, which is currently 6.5%. This is the standard across the state, but in some regions there are additional amounts added to this, including 3% in Seattle and King’s County.

I pay cash or use zelle so I don't pay tax or claim it, there is a stiff penalty for gains on your silver in the US!
See you CPA about that
