I am in the 15% tax bracket. In terms of short term hold and long term hold, I want to know what the differences in taxes rules for specialty ETFs such as GLD (Gold ETF) and general ETFs as are?
Gold ETFs are treated different than stock ETFs, as a collectable. This makes long-term investing in gold ETFs (for one year or longer) subject to a relatively large capital gains tax (maximum rate of 28%, rather than the 20% maximum rate that is applicable to most other long-term capital gains).
