The founder's guide to keeping more at exit
Direct answers to the four questions that determine how much of a liquidity event founders actually keep: proceeds, QSBS, residency, and estate timing. Built for venture-backed founders preparing for a tender, secondary, acquisition, or IPO.
What reduces founder proceeds at exit
Federal and state capital gains tax, AMT on early exercise, missed QSBS eligibility, ordinary-income treatment on NSOs, and uncoordinated estate transfers are the largest reductions to founder proceeds at exit.
Most founders see their take-home shrink in five places: federal long-term capital gains on the gain above any QSBS exclusion, state capital gains tax in the state of residency at sale, AMT triggered by ISO exercises in the year of exercise, ordinary income on NSOs and on disqualifying ISO dispositions, and transfer taxes if shares are gifted late or to the wrong vehicle. Each of these is a timing problem before it's a tax problem; decisions made 1 to 5 years before a transaction usually have a larger impact than anything done in the 90 days before close.
What QSBS is and why early tracking matters
QSBS (Qualified Small Business Stock) under Internal Revenue Code Section 1202 allows eligible shareholders to exclude up to $10 million (or 10x cost basis, whichever is greater) of federal capital gains per taxpayer when shares are held for at least five years.
Eligibility is determined at issuance: the company must be a domestic C-corporation with gross assets at or under $50 million when the stock was issued, in a qualifying trade or business. Because the exclusion is per taxpayer, gifting QSBS to a spouse, children, or properly structured non-grantor trusts before a sale can multiply the exclusion. A married couple with two children can potentially exclude up to $40M in gains, and more with trust stacking. See the full QSBS guide.
How state residency affects exit taxes
State income tax on a liquidity event is generally owed to the state where the founder is a tax resident on the date of sale, not where the company is headquartered. Establishing or changing residency typically takes 6 to 24 months and requires documented facts.
California, New York, New Jersey and other high-tax states audit residency changes around liquidity events aggressively. States also differ on whether they conform to the federal QSBS exclusion; founders in non-conforming states may owe full state capital gains even when federal tax is excluded.
Why estate and trust timing matters before a liquidity event
Estate and trust planning done before a liquidity event can transfer future appreciation out of the taxable estate at a lower valuation and can multiply QSBS exclusions. The same planning done after a deal announcement loses most of its value.
Common pre-transaction structures include grantor retained annuity trusts (GRATs), intentionally defective grantor trusts (IDGTs), and non-grantor trusts for QSBS stacking. For 2026, the federal lifetime gift and estate tax exemption is $15 million per individual.
Default path vs the Frame path
| Decision area | Default path | Frame path |
|---|
| QSBS tracking | Eligibility reconstructed at exit from old cap-table emails. Single $10M exclusion claimed or missed. | Eligibility tracked from issuance. Trust-stacking modeled so a married couple with two children can target up to $40M excluded (about $2.38M tax savings per $10M excluded). |
| State residency | Residency considered weeks before close, often too late to establish defensibly. | Residency scenarios modeled 6 to 24 months out, with state conformity to QSBS factored in. |
| Coordinated advisory | Separate CPA, attorney, and wealth manager, each with partial context. | SecureMatch™ pairs founders privately with vetted RIAs, CPAs, M&A advisors, and estate attorneys who share the same FrameIQ™ model of the household. |
| Estate & trust timing | Estate planning started after term sheet, at a higher valuation. | Pre-transaction GRATs, IDGTs, and non-grantor trusts modeled while valuations are still low. |
