Sequencing a secondary: tax-aware liquidity for venture-backed founders.

Most secondaries we see are structured by the company's general counsel and the lead investor's deal team. Both of them are optimizing for the company. Neither of them is optimizing for the founder's personal tax outcome — and the founder's personal tax outcome is rarely a small number. Our practice has closed enough secondaries to assert this with confidence: the difference between a well-sequenced secondary and a default one regularly costs the founder seven figures of after-tax proceeds on a $20–50M sale.

Why secondaries are not a tax event you can outsource

At the company level, a secondary is structurally simple: a tender for a fixed number of shares at a fixed price. At the founder level, it is the convergence of every prior tax decision the founder has made — the founder stock acquisition, the §83(b) election (or absence of one), every ISO exercise, the disqualifying disposition history, the AMT carryforward balance, the QSBS clock on each lot, and the founder's current state of domicile measured against the state where the work was performed.

Each of those decisions has an interaction effect with the others. The wrong sequence of share lots sold at the secondary can blow QSBS qualification on the highest-value remaining position. The right one can preserve a $10M+ exclusion for a future event.

QSBS and the 5-year clock — what survives, what doesn't

Section 1202 requires the qualifying stock to be held for five years before sale. In a secondary, founders typically hold a mix of lots: some that have cleared the five-year clock, some that are close, and some that have not. The default selection — typically oldest lots first — is usually correct. But not always.

• If the company's QSBS qualification is at risk going forward (asset thresholds, redemption activity, business-line shifts), selling lots that already qualify may be the right move now while the exclusion is secure.
• If the founder has multiple §1202 stacks across grantor trusts, coordinating which trust sells which lot can multiply the available exclusion — sometimes by 5×–10×.
• If a §1045 rollover is on the table, lots that have not yet cleared the five-year clock can be sold and reinvested into replacement QSBS within 60 days, preserving the qualification across the rollover.

1045 rollovers when the clock isn't ripe

§1045 is underused, often because founders and their existing advisors do not realize it applies. A lot of qualifying QSBS held for at least six months but less than five years can be sold, rolled into replacement QSBS within 60 days, and the holding period of the original stock tacks onto the replacement. For a founder with secondary proceeds and an active angel-investing practice, this is a near-mechanical way to defer the gain and preserve the §1202 trajectory on the rollover.

AMT implications when shares were ISO-exercised

If the secondary lots include shares that were exercised as Incentive Stock Options, the founder is sitting on a buried AMT question. A disqualifying disposition (sale within one year of exercise or two years of grant) converts the previously-AMT-only spread into ordinary income — which can trigger or release AMT credits in a way that is rarely intuitive.

We model AMT for every founder approaching a secondary on a per-lot basis. Often the result is to deliberately structure the secondary as a disqualifying disposition for a specific tranche of ISO-exercised shares — not because anyone wants the ordinary income, but because it releases multi-year AMT credit balances that would otherwise sit unused.

State sourcing

For founders who relocated during the company's growth, the state sourcing question is the largest single variable in the post-tax outcome. California, in particular, will assert sourcing on equity attributable to in-state work — even years after the founder relocates. The answer is not "I moved to Florida last year, the gain is Florida-source." The answer is granular, lot-by-lot, and depends on the proportion of vesting that occurred while the founder was a California resident. Our domicile strategy framework covers the full residency analysis that underpins this work.

We build a per-lot sourcing analysis before the secondary closes, not after — this is core to our tax strategy work for venture-backed founders. The result is sometimes that the secondary is timed to a future tax year to allow additional non-California vesting to cleanse the position. Sometimes it is to deliberately accelerate certain lots to consume California exposure now while the rate environment is favorable. Both are tactics. Neither is intuitive without the model.

A note on relocation timing

The cleanest fact pattern is a domicile change that is established, documented, and fully severed for a full tax year before any secondary or sale. Anything compressed into the same year as the liquidity event creates argument surface that the founder will spend the next four years defending. Plan the move 18 months ahead of the event, not three.

Coordinating with primary capital

Most secondaries happen alongside a primary round. The founder-level decisions are easier to optimize when they are sequenced into — not negotiated against — the company's capital plan. We engage with the company's CFO and the lead investor on the structure of the tender itself: who is eligible, how the cap is calibrated, whether the price is at a premium or discount to the primary, and how the proceeds are sourced.

These are not one-sided conversations. Companies have an interest in their founders ending the round in a financial position that supports the next four years of execution. Founders who arrive at the negotiation with a structured ask — rather than a raw "I want to sell as much as possible" — almost always get a better outcome on both sides.

A clean playbook

1. 90 days out: per-lot basis schedule, QSBS qualification memo, AMT carryforward reconciliation, state sourcing model.
2. 60 days out: trust planning — if any portion is moving into a SLAT, dynasty trust, or charitable vehicle, the structure has to be funded and seasoned ahead of the secondary, not after.
3. 30 days out: finalize lot selection, confirm trust ownership of the selected lots, file any required §83(b) confirmations, lock the §1045 rollover targets if applicable.
4. At close: coordinate withholding, document basis for 1099-B reconciliation, capture state sourcing positions in contemporaneous memos for the file.
5. Post-close: within 60 days, complete §1045 rollovers if applicable; within 12 months, complete trust funding strategies that depend on the post-secondary balance sheet.

None of this is exotic. All of it is sequence-dependent. The secondaries we see go badly almost always go badly because the sequence collapses — decisions that needed to be made in the 90-day window get made on the close date, and the optionality is gone.
