How can you even think about making money or braking even for that matter when buying bullion on eBay, this is even for dealers that are in the same state as me which is mind boggling ! as my state offers no sales tax on bullion what ever the amount is at my LCS, neighboring states such as California offer no sales tax of purchases over $2,000 I am currently looking for a 500 gram bar but my LCS says these are tough to come by but I think I got a connection in California that can get me what iam looking for and save over $900 in tax.
Be careful of what you wish-for, when trying to "break-even" while "trading" P.M.. EBay has recently sent me a T.O.S. update in response to my legal challenge of their with-holding purchase funds. They've blocked funds access from both parties in an eBay sales dispute, after they've received their "service-fees".
you have to admit that major bullion purchases on eBay are a loser ! in comparison to a no tax situation though I may still consider to buy certain coins but they would have to really WOW me !
This is free advice, worth at least your cost! You probably should get Federal tax advice from reliable counsel, before posting YOUR understandings. JMHO
If you haven't had a Federal Tax Audit, believe me, it is a humbling experience, and the ramifications for INTENTIONAL tax evasion can be very significant, as an automatic gross misdemeanor (i.e. Felony). I believe: Physical gold and silver investments are subject to capital gains tax, calculated based on the difference between the price you paid and the price you sold it for. The Internal Revenue Service (IRS) classifies gold and silver as collectibles. Hence, they are taxed at a maximum rate of 28% on long-term capital gains. If the gold or silver is yours for less than a year, any gains are taxed as ordinary income, which is often higher than the long-term capital gains rate.
