📝 Executive Summary
Investors in physical gold ETFs like IAU face a 28% collectibles tax rate on long-term gains, significantly higher than the 15% long-term capital gains rate applied to equity funds like VOO. Beyond the tax disparity, structural expense ratios vary, with GLDM offering a lower 0.10% fee compared to IAU's 0.25%, though all physical gold grantor trusts remain subject to the same unfavorable IRS tax treatment.
