Wealthy Startup Investors Face New Tax Squeeze as States Target QSBS Break

The original story by Hayley Cuccinello for CNBC.

A tax break long adored by startup founders and venture investors is suddenly under pressure at the state level, even after Washington moved to make it more generous.

The provision, known as qualified small business stock or QSBS, got a major boost under the One Big Beautiful Bill Act. But several states are now pushing back, arguing the incentive overwhelmingly benefits wealthy investors cashing out huge startup gains.

Maine and Oregon have become the latest states to break away from the federal treatment of QSBS, meaning residents selling qualifying startup stock will still owe state income taxes on those profits. Similar efforts surfaced in New York and Washington state, though they failed to pass.

That shift is already setting off alarms among tax lawyers who advise ultra-wealthy clients and startup founders.

“Tax policy has consequences,” said David Blum, chair of Akerman’s national tax practice group.

For wealthy investors sitting on potentially massive startup exits, he added, changing residency may suddenly look a lot more attractive.

QSBS was originally created during the Clinton years to encourage investment in small businesses. Under federal rules, investors who hold qualifying startup shares for at least five years can exclude a large chunk of capital gains taxes when they sell.

The latest federal overhaul made the incentive even sweeter. The maximum exclusion climbed from $10 million to $15 million, while the size threshold for eligible companies rose from $50 million to $75 million in gross assets.

Critics say the tax break has drifted far from its original purpose.

Treasury Department research found taxpayers earning more than $1 million account for nearly three-quarters of the gains excluded under QSBS rules. That has turned the provision into a growing political target as states search for revenue after federal funding cuts.

California – despite being the center of the venture capital universe – already taxes QSBS gains at the state level. Alabama, Mississippi and Pennsylvania do too.

Some wealthy investors are already thinking ahead. Steve Oshins, a lawyer who specializes in estate and tax planning, said higher state taxes could accelerate moves to lower-tax states like Florida or Nevada.

The rules hinge largely on where an investor officially lives when the stock sale happens. That gives people time to restructure things, sometimes through trusts established in states with no income tax.

Oshins pointed to Nevada and Wyoming as popular options. An Oregon resident, for example, could potentially transfer shares into a specially structured trust based in Nevada before selling, shielding the gains from Oregon taxes under certain conditions.

Maine’s rules are tougher. Trust income can still face taxation there if the trust was created or funded by a Maine resident.

Even so, some advisers say the cleanest solution is simply relocating before a liquidity event hits.

But changing domicile is harder than buying a second home and updating voter registration. States increasingly scrutinize wealthy residents trying to leave for tax reasons. Tax authorities look at everything from where someone spends most of the year to where their family, doctors and primary social ties are based.

“You really have to move and uproot your life,” Blum said.

For states betting that richer residents will stay put and pay up, that may prove an expensive assumption.
