“Q.S.B.S.” is a tax related acronym in the U.S. for Qualified Small Business Stock. When a start-up corporation meets certain conditions enumerated in Code §1202, noncorporate investors are offered the opportunity to derive tax-free capital gains by holding the investment for a period of time prior to a liquidity event. The greater of $10 million of gain or 10 times the taxpayer’s basis in the Q.S.B.S. – referred to as “basis loading – may be exempt from tax on exit. The tax benefit can be enhanced by creating multiple irrevocable nongrantor trusts, each formed for the benefit of a specific family member. Each trust is entitled to its own capital gain exemption, so long as the multiple trust rule of Code §643(f) is not triggered. Under that rule, multiple trusts having (i) the same grantor, (ii) substantially the same primary beneficiaries, and (iii) an income tax avoidance purpose are treated as a single trust.. Among savvy investors, the tax plan is known as “stacking.” In her article, Galia Antebi reports that Treasury Assistant Secretary for Tax Policy Kenneth Kies recently signaled that Treasury does not like stacking. The bad news is that forthcoming Q.S.B.S. guidance is expected to limit taxpayers’ ability to multiply the benefit. The good news is that basis loading is not a target – at least for now.
