QSBS Specialist Advisory for Venture-Backed Founders

Keystone Global Partners works with venture-backed tech founders to plan, structure, and implement QSBS strategies before and during an exit.

You spent years building your company. When it’s time to sell, Section 1202 of the tax code could let you exclude millions of dollars in gains from federal taxes.

But the rules are complicated. Miss a detail, and you could owe millions more than necessary. Our co-founder, Peyton, is recognized as one of the leading QSBS specialists in the country, with deep expertise in practical implementation for $20M+ exits.

01

Section 1202 Exclusion Analysis

Before building any strategy, we confirm your stock qualifies and determine what exclusion percentage applies.

The One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, created new rules for stock acquired after that date. Stock issued on or before July 4, 2025 remains under the prior rules.

Your exclusion depends on when your stock was issued:

Stock IssuedHolding PeriodExclusion
After September 27, 2010 and on or before July 4, 2025More than 5 years100%
After July 4, 2025Less than 3 years0%
After July 4, 2025At least 3, less than 4 years50%
After July 4, 2025At least 4, less than 5 years75%
After July 4, 20255+ years100%

Stock acquired before September 28, 2010 falls under legacy 50% or 75% tiers with different AMT treatment.

We also review your company’s eligibility based on entity type, company gross assets before and after stock issuance, and the active business requirement. The aggregate gross assets test caps company assets at $50 million for stock issued on or before July 4, 2025, and $75 million for stock issued after that date, measured using cash + the adjusted tax basis, rather than fair market value, at all times before and immediately after issuance.

Note: for stock issued after July 4, 2025, the exclusion cap is the greater of $15 million or 10 times your adjusted basis, per taxpayer, per issuer (the $15 million is indexed for inflation beginning in 2027). For stock issued on or before that date, the cap is the greater of $10 million or 10 times basis.

02

Mixed Tranche Analysis

Most founders hold multiple stock positions with different acquisition dates and different rules. Founder shares from 2019, options exercised in 2022, and shares issued in late 2025 under the new rules each follow their own exclusion percentage, holding period, and cap.

We analyze every tranche separately, calculate the total exclusion potential across all positions, and flag any gaps before they become a problem at closing.

03

Exit Timing Strategy

For founders holding post-OBBBA stock, a few months can make a significant difference. Waiting from three to five years of holding moves a founder from a 50% exclusion to a 100% exclusion. On a $15 million gain, the difference in federal taxes is over $2 million.

We model whether adjusting your exit timeline makes financial sense, factoring in deal certainty, market conditions, and your personal goals.

04

Deal Structure Review

How your deal is structured determines whether you keep your QSBS benefit.

Deal StructureQSBS Treatment
Direct stock saleSection 1202 exclusion preserved
Asset saleExclusion generally eliminated
338(h)(10) electionTreated as asset sale; exclusion generally eliminated
Stock-for-stock merger (Section 368)Exclusion preserved up to built-in gain at closing; future appreciation generally not covered

We review purchase agreement terms and tax elections before you sign to catch any structural issues that could wipe out an exclusion you spent years building.

05

QSBS Stacking Strategies

If your exit exceeds the exclusion cap, stacking can expand your total tax benefit. Stacking works by gifting shares to multiple qualified taxpayers before the exit. Each separate taxpayer qualifies for their own exclusion cap.

Example: how stacking expands total exclusion (post-OBBBA stock)

TaxpayerPer-Issuer Exclusion Cap
Founder$15M
Non-grantor trust (first)$15M
Non-grantor trust (second)$15M
Family member (separate taxpayer)$15M
Total potential exclusion$60M

A few things that matter here:

  • Grantor trusts do not create a separate taxpayer and will not multiply your exclusion
  • Non-grantor trusts are separate taxpayers and can qualify for their own cap if drafted correctly.
  • Multiple trusts must be meaningfully different (beneficiaries, trustees, terms). Carbon-copy trusts can be collapsed into one taxpayer under Section 643(f)
  • Transfers made after a sale is practically certain could fail, and be considered an assignment of income by the IRS


A true QSBS specialist understands that timing is everything. Stacking requires planning well ahead of any LOI or exclusivity agreement.

06

Trust Planning and Entity Structuring

As QSBS specialists, we coordinate with qualified tax and legal professionals to align your QSBS strategy with your broader trust and estate goals.

Services in this area include:

  • Non-grantor trust and other types of structuring to expand the total exclusion
  • QSBS Packing, if applicable
  • Charitable planning
  • Generation-skipping trust planning for multi-generational wealth transfer
  • Family office coordination

07

State Tax Planning

Federal exclusion is only part of the picture. State treatment varies significantly.

StateConforms to Federal QSBS?Notes
CaliforniaNo13.3% state capital gains tax still applies
PennsylvaniaNoDoes not conform
AlabamaNoDoes not conform
MississippiNoDoes not conform
Washington D.C.NoDecoupled retroactive to January 1, 2025 (temporary legislation; status evolving)
OregonNoAddback required for tax years beginning on or after January 1, 2026
New JerseyYesConforms starting January 1, 2026
New YorkYesFull conformity, including for NYC residents
Most other statesYesGenerally follow the federal exclusion, though several states have partial or evolving rules. State treatment is a moving target and should be verified for your situation

We help founders understand their full state tax exposure and plan accordingly. That may include residency planning (24 to 36 months before exit offers the most planning room), non-grantor trust structures in conforming jurisdictions, and timing strategies for founders in recently updated states.

08

Section 1045 Rollover Planning

If you sell QSBS you have held for more than six months but have not yet met the exclusion holding period, a Section 1045 rollover lets you defer tax by reinvesting proceeds into new qualifying stock within 60 days of the sale. Your original holding period carries over to the replacement stock.

This is a deferral strategy, not a permanent exclusion. It works best when you plan to deploy capital into another qualifying startup. We model whether it fits your exit, and we handle the coordination so the replacement stock stays on track for its own future exclusion.

Personal Exit Advisory Program

If your exit is between zero and three years out, please reach out to discuss our Personal Exit Advisory® program.

The goal is simple: the planning decisions you make before your exit determine how much of your exit you actually keep. By the time you have an LOI on the table, some options are no longer available.

This program covers:

Personal CFO service with interactive exit and tax scenario modeling
Section 1202 qualification, stacking, and trust strategy development
State domicile and residency planning
Liquidity and deal strategy, including secondary sales and tender offers
Equity compensation planning (option exercise timing, 83(b) elections)
Coordination with your existing legal and tax team

Real estate and liquidity planning
Life and identity transition support

What Most Advisors Get Wrong

QSBS planning is not a checklist. The rules interact in ways that depend on your specific situation.

A few mistakes we see regularly:

Using the stock option grant date instead of the exercise date to start the QSBS clock
Treating grantor trusts as separate taxpayers for stacking purposes
Improperly drafted trust instruments
Assuming a specific number of months before an exit creates a legal safe harbor for gifting shares (there is no IRS bright-line rule)
Not accounting for state non-conformity, especially for California-based founders

Each of these errors can cost millions. Catching them requires a QSBS specialist who regularly works in this space.
