The TMTG Act would limit how much investment gains executive branch officials, including the President and Vice President, can defer when selling property to resolve conflicts of interest. Currently, federal law allows these officials to avoid immediate taxes on investment profits if they sell assets to comply with conflict-of-interest rules, but this bill caps that tax deferral at $100 million per person across their entire career in government. If an official leaves office before using up their deferral allowance, any remaining deferred gains would become immediately taxable in that final year of service. The bill applies to all property sales after it is enacted and makes technical changes to how the tax code handles these deferrals going forward.
