State Tax Implications for QSBS Benefits: Where You Live Matters

Quick Overview

While Section 1202 QSBS benefits can provide up to 100% exclusion of gains from federal income tax, state tax treatment varies significantly. This article breaks down how different states handle QSBS exclusions, identifies the states that don't conform to federal QSBS treatment (CA, NJ, AL, MS, PA), explores strategic residency planning opportunities, and explains why establishing Nevada trusts can save millions in taxes for founders and investors with QSBS stock.

Why State Taxes Matter for QSBS Planning

When I talk to founders about QSBS benefits, they're often focused solely on the federal tax exclusion—and understandably so. The ability to exclude up to $10 million (or 10x your basis) in capital gains from federal taxation is an incredible benefit. But what many overlook is the significant impact of state taxation.

Consider this scenario: you founded a company, invested $100,000, and your shares are now worth $10 million. With proper QSBS planning, you'll pay zero federal tax on that gain. However, if you live in California, you'll still owe approximately $1.33 million in state taxes (at CA's 13.3% top rate). That's a seven-figure difference that could have been potentially avoided with proper planning.

States That Don't Conform to Federal QSBS Treatment

Not all states follow the federal government's lead when it comes to QSBS benefits. Currently, five states explicitly don't conform to the federal QSBS exclusion:

1. California (13.3% top tax rate)

2. New Jersey (10.75% top tax rate)

3. Alabama (5% top tax rate)

4. Mississippi (5% top tax rate)

5. Pennsylvania (3.07% flat tax rate)

If you reside in one of these states when you sell your QSBS shares, you'll pay state tax on the full gain, even if it's excluded from federal taxation.

States with Full QSBS Conformity

The good news is that most states fully conform to the federal QSBS provisions, allowing the same exclusions at the state level that you receive federally. This includes states with some of the highest tax rates, such as:

• New York (10.9% top rate)

• Oregon (9.9% top rate)

• Minnesota (9.85% top rate)

• Vermont (8.75% top rate)

• Wisconsin (7.65% top rate)

When you sell qualifying QSBS in these states, you receive the same exclusion for both federal and state taxes—potentially saving millions compared to non-conforming states.

Zero Income Tax States: The Ultimate QSBS Haven

Nine states currently have no income tax at all, making them particularly attractive for QSBS planning:

1. Alaska

2. Florida

3. Nevada

4. New Hampshire

5. South Dakota

6. Tennessee

7. Texas

8. Washington

9. Wyoming

For QSBS holders, these states offer a clear advantage: even if federal QSBS rules change or your stock doesn't fully qualify, you won't face state income tax on your gains.

The Combined Tax Impact: Federal + State

To understand the true impact of state non-conformity, let's look at the total tax rate (federal + state) on QSBS gains that exceed the exclusion limit or don't qualify:

• California: 37.1% (23.8% federal + 13.3% state)

• New Jersey: 34.55% (23.8% federal + 10.75% state)

• New York: 34.7% (23.8% federal + 10.9% state)

• Oregon: 33.7% (23.8% federal + 9.9% state)

• Nevada: 23.8% (federal only, no state tax)

This illustrates why strategic planning around state residency can be just as important as meeting the federal QSBS requirements.

To put these rates in perspective, consider how they compare to ordinary income and short-term capital gains taxation:

For those who don't qualify for QSBS or who sell before meeting the 5-year holding period, the tax hit can be substantially higher. Short-term capital gains (for stock held less than a year) are taxed at ordinary income rates, currently up to 37% plus 3.8% net investment income tax (NIIT) federally. Add state taxes, and a California-based founder could face a staggering 54.1% combined tax rate (37% + 3.8% + 13.3%) on their gains.

Even without QSBS, holding stock for at least a year to qualify for long-term capital gains rates (20% + 3.8% NIIT) can save a founder approximately 17% in federal taxes compared to short-term rates. But the full QSBS exclusion eliminates that 23.8% federal tax entirely - a significant advantage over standard long-term capital gains treatment.

This tax differential shows why many founders carefully plan both their company structure and personal finances to maximize QSBS benefits. Even when your gains exceed the QSBS limits, qualifying for long-term capital gains on the remainder still provides substantial tax savings compared to ordinary income rates.

QSBS Stacking and State Tax Planning

When implementing a QSBS stacking strategy (as discussed in previous articles), state tax considerations become even more critical. If you're stacking QSBS benefits across multiple trusts to exclude tens of millions in gains, the state tax implications can easily reach seven or eight figures.

This is a primary reason why we custody all of our QSBS trusts in Nevada at Promissory. Nevada offers:

1. No state income tax

2. Strong asset protection laws

3. No information sharing agreement with the IRS

4. Favorable trust laws that allow for dynasty trusts

When I set up my own QSBS stacking strategy, I established trusts in Nevada specifically to avoid California's non-conformity with QSBS benefits. This single decision saved millions in potential state taxes.

Timing Is Everything: Establishing Residency

If you're considering changing residency for QSBS tax purposes, timing is critical. States like California are known for aggressively pursuing former residents who sell significant assets shortly after moving away.

For QSBS planning, consider:

1. Establishing clear residency in a tax-favorable state at least 1-2 years before a planned sale

2. Cutting ties with your former high-tax state (property, voter registration, etc.)

3. Documenting your presence in your new state (at least 183 days per year)

4. Moving assets to trusts in favorable jurisdictions well before a liquidity event

Pro Tip: If you've already established residency in a high-tax, non-conforming state, setting up non-grantor trusts in favorable jurisdictions for future QSBS gifts may still provide significant benefits since the trust's residency, not yours, will determine state tax treatment on those shares.

Promissory’s Strategy

Uprooting your life for tax savings is less than ideal for anyone, even when there are millions of dollars at stake. That’s why we typically see our users gift only a portion of their stock to a Nevada based trust. This allows you to exclude a portion of your gains from state taxes while still establishing a full $10m exclusion at the federal level. 

Most users will maintain a majority ownership of 50-70% of their stock, under their direct ownership, in the state that they reside. This enables them to use the funds immediately and at their own discretion, even if it means paying state tax on their gains – the freedom and immediate liquidity is worth the trade.

The remaining 50-30% will be gifted into Nevada based trusts for the benefit of their spouse, children, or future children. This allows each trust to realize the full benefit of tax free gains, and to utilize the funds for purposes specified by you. 

The benefits and ROI of this approach are huge! Even if it’s $1m gifted to a trust, that could be the difference between an additional $133,000 that could benefit from compounding and investment putting your beneficiaries farther ahead.

Pro Tip: Even if you don’t want to establish residency in a tax-favorable state, gifting just a portion of your QSBS to Nevada-based trusts can still save significant taxes while maintaining control over most of your assets.

Legislative Trends to Watch

State taxation is constantly evolving, with budget pressures sometimes leading states to decouple from federal tax benefits. Currently, we're seeing:

1. Some states considering adopting QSBS conformity to attract startup investment

2. Other states (particularly those with budget shortfalls) considering eliminating conformity

3. Increasing scrutiny of residency changes before major liquidity events

While the current administration has signaled support for QSBS benefits at the federal level, state-level conformity remains less predictable.

Check Your Potential Tax Savings

Not sure how much state taxes affect your QSBS benefits? We've built a handy calculator that compares potential tax outcomes based on residency. For someone with $10 million in QSBS-eligible gains, the difference between holding all of your equity in California or transferring a portion to a Nevada based trust could be upwards of $1.33 million in tax savings—money that compound and grow and set up your beneficiaries for generations.
