IPO Financial Planning for Founders and Executives

Not tax or legal advice. Verify all strategies with qualified tax and legal counsel before acting.

A company going public is the largest liquidity event most founders and senior executives will ever experience. A founder with 2 million shares at a $40 IPO price holds $80 million in paper wealth — and has a narrow, 12-to-18-month window before and after the offering to make decisions that will determine how much of that wealth survives taxes, reaches heirs, and gets productively deployed. Get the sequencing wrong and you can lose $15M–$25M to avoidable tax, lock yourself into a concentrated position you can't exit cleanly, or trigger California income tax on equity that should have been pre-exit stock.

This guide covers the full IPO planning arc: what to do 12+ months before the S-1 filing, how to navigate the lockup, and how to build a post-lockup diversification plan that doesn't sacrifice the upside you waited years for.

The pre-IPO planning timeline

The planning value is concentrated in the period before the company files its S-1 registration statement with the SEC. Once the S-1 is on file, you're inside a quiet period, trading restrictions tighten, and the opportunity to make pre-IPO gifts of low-value shares largely closes. The timeline works backward from filing date:

The common mistake: waiting until the S-1 is filed or the IPO is priced to start planning. By that point, every share is worth multiples of its pre-IPO 409A valuation, and the window for low-cost estate transfers is gone.

Pre-IPO gifting: GRATs, IDGTs, and direct gifts

Pre-IPO equity is priced at the most recent 409A appraisal — typically a fraction of expected IPO price. That discount is the gift-tax arbitrage window. A founder holding shares at a $5 409A valuation who gifts them before IPO at $40 has transferred $35 per share of appreciation to heirs free of gift or estate tax. The mechanics:

GRATs with pre-IPO shares

A grantor retained annuity trust (GRAT) lets you transfer appreciation above the IRS §7520 hurdle rate (5.0% for May 2026)¹ with no gift tax cost. A zeroed-out GRAT is structured so the present value of your annuity payments back equals the contribution — zero taxable gift. If the assets appreciate faster than the §7520 rate, the excess passes to heirs tax-free.

Pre-IPO is the ideal GRAT asset for two reasons: (1) low starting valuation makes the §7520 hurdle easy to clear, and (2) the binary nature of an IPO event (low before, high after) creates exactly the kind of "lumpy" appreciation that GRATs are designed to capture. A rolling series of 2-year GRATs loaded with pre-IPO shares, timed to mature after IPO, can transfer tens of millions to heirs free of estate tax. See our GRAT calculator to model the transfer math.

Intentionally defective grantor trusts (IDGTs)

An IDGT installment sale lets you sell pre-IPO shares to an irrevocable trust in exchange for a promissory note at the applicable federal rate (AFR). The trust owes you interest, but all appreciation above the AFR passes to trust beneficiaries free of gift and estate tax — and because the trust is "defective" for income tax purposes, you pay the income tax on trust gains, which is itself an additional gift-tax-free transfer. For a founder with $50M in pre-IPO equity, an IDGT sale can move $30M–$40M outside the estate at minimal transfer-tax cost if executed early.

Direct gifts of pre-IPO shares

You can give $19,000 per recipient per year in 2026 free of gift tax.² Married couples can combine for $38,000 per recipient. For shares valued below the annual exclusion, direct gifts to children, grandchildren, and trusts for their benefit are completely gift-tax free. The lifetime exemption is $15M per person in 2026 under OBBBA (permanent) — so for most founders, using the $15M exemption on pre-IPO shares at 409A value is the highest-leverage use of that exemption.³

QSBS: the $15M exclusion opportunity

If your company is a qualified small business at the time of stock issuance and you've held the shares for at least three years, §1202 excludes up to $15M in gain from federal capital gains tax (OBBBA permanently raised this from $10M).³ The tiered exclusion under OBBBA: 50% for 3-year holds, 75% for 4-year holds, 100% for 5-year holds — for stock acquired after January 19, 2025. For stock acquired earlier, prior law applies (100% exclusion for stock acquired after September 27, 2010).

The QSBS exclusion does not eliminate the California income tax — California never conformed to federal QSBS treatment, so CA residents owe the full 13.3% on the excluded gain regardless of federal exclusion.⁴ QSBS planning and domicile planning must be sequenced together for California-based founders.

ISO/AMT strategy around IPO

ISOs create the most complex planning challenge at IPO because exercising large blocks of in-the-money ISOs creates AMT liability even though you receive no cash at exercise. The 2026 AMT exemption is $140,200 MFJ, phasing out at 50 cents per dollar of AMTI above $1,000,000 MFJ under OBBBA.⁵

For a founder holding ISOs with a $2 exercise price when shares are at a $40 409A value, exercising 100,000 ISOs creates $3.8M in AMT preference income ($38 spread × 100,000 shares). That preference income can produce $1M+ in AMT if already above the exemption phaseout threshold — a cash tax bill with no corresponding cash. This is the "AMT trap": you're taxed as if you received cash you haven't yet.

The pre-IPO exercise strategy

Exercising ISOs at a low 409A valuation (say, $5 per share) when you expect the stock to reach $40 at IPO minimizes the AMT preference income and starts the LTCG holding period clock. Key variables:

• AMT capacity check. How many ISO shares can you exercise before hitting AMT, given your regular tax position? The answer changes every year and depends on ISO spread, other income, and deductions. A tax advisor models this per year.
• Cash to exercise. Early ISOs require cash for exercise price plus AMT. Many founders fund from secondary sales, venture debt against unvested shares, or pledged-asset lines on other assets.
• Holding period clock. ISO exercises must be held 1 year from exercise date AND 2 years from grant date for qualifying disposition (LTCG) treatment. Exercising 12 months before IPO means shares can be sold at LTCG rates within 3–6 months post-lockup.
• Risk of stock decline. If the company doesn't go public or the stock falls, you hold shares you exercised at current 409A value and may have paid AMT on a preference item that's now worth less than the tax. The 83(b) election (for restricted stock, not ISOs) and ISO exercise timing should be stress-tested for downside scenarios.

RSU cliff vesting at IPO

Many pre-IPO companies grant RSUs with a "double-trigger" vesting condition: the shares vest only when both (1) a time-based schedule is satisfied and (2) a liquidity event occurs. At IPO, the liquidity trigger fires and all double-trigger RSUs vest simultaneously — creating a large ordinary income event in a single year.

The tax treatment is simple but the amount is large: the FMV of RSUs at vesting is W-2 compensation at your marginal rate. For an executive vesting $10M in RSUs at IPO, that's $3.7M in federal income tax plus California income tax at 13.3% (if resident). Companies typically withhold at the 22% supplemental rate for the first $1M and 37% above — creating a withholding gap at UHNW levels. You'll owe additional taxes at year-end or need to make quarterly estimated payments.

The planning moves are limited: RSU vesting creates ordinary income regardless of what you do. What you control is (1) the state of domicile at vesting (a resident of Nevada or Florida owes no state tax), (2) the timing of any charitable offset (fund a DAF with appreciated shares in the same year to generate a deduction against the RSU income), and (3) how quickly you diversify from shares received at vesting to avoid concentration in a single stock.

10b5-1 plans: the 2023 rule changes

A Rule 10b5-1 trading plan lets executives and directors set up a pre-scheduled program to sell shares — including post-lockup sales — without the insider trading exposure that comes from selling while potentially in possession of material nonpublic information (MNPI). The plan must be established at a time when you are not aware of MNPI. Once in place, sales execute automatically per the schedule.

The SEC's December 2022 amendments (effective February 27, 2023) significantly tightened the rules:⁶

• Cooling-off period. Officers and directors must wait the later of: (a) 90 days after plan adoption, or (b) two business days after filing the 10-Q or 10-K covering the fiscal quarter in which the plan was adopted — subject to a maximum 120-day cooling-off period. Non-officer/director insiders have a 30-day cooling-off period.
• Representations required. At plan adoption, officers and directors must certify in writing that they are not aware of MNPI and are adopting the plan in good faith, not as part of a scheme to evade insider trading rules.
• Single-plan restriction. Officers and directors may not have more than one outstanding 10b5-1 plan at a time (with narrow exceptions for a second plan covering shares from an employee benefit plan).
• Cooling-off on modifications. Modifying a 10b5-1 plan is treated like adopting a new plan — the full cooling-off period restarts.

Lockup mechanics and expiry planning

Underwriters typically require that all officers, directors, and significant shareholders sign lockup agreements prohibiting share sales for 180 days after IPO pricing.⁷ The lockup is not SEC-mandated — it's a contract term negotiated between the company and underwriter. Employees below the threshold (often non-officer employees with fewer than a certain share count) may have shorter or no lockup obligations.

Key considerations around lockup expiry:

• Early release clauses. Some lockups include early release provisions if the stock trades at a premium to IPO price for a defined period, or if the underwriter consents. Read the lockup agreement before assuming 180 days is fixed.
• Blackout windows. Even after lockup expiry, most public companies prohibit trading during pre-earnings quiet periods (typically 30 days before each quarterly earnings release). Lockup expiry may land inside a blackout window — meaning the effective first trade date is later than day 181.
• The "lockup expiry overhang." On the day lockup expires, insider supply hits the market. Stock prices often decline 5–15% around lockup expiry on high-supply names. A well-constructed 10b5-1 plan schedules sales across multiple trading windows rather than concentrating sales at lockup expiry.
• Holding period for LTCG. Shares acquired at IPO (or exercised pre-IPO) qualify for LTCG treatment after one year from acquisition date. For an executive exercising ISOs in the 12 months before IPO, the LTCG clock may already be running — allowing LTCG sales shortly after lockup expiry if the holding period is met.

California and state tax at IPO

California-resident founders and executives face a unique tax burden at IPO: California's 13.3% top marginal rate applies to capital gains and ordinary income with no favorable rate for long-term capital gains.⁴ Combined with federal LTCG and NIIT, a California resident selling post-IPO stock faces a combined rate of up to 37.1% (23.8% federal + 13.3% CA) on long-term gains.

The equity apportionment trap

California apportions income from equity compensation based on the ratio of days worked in California to total vesting period. For unvested RSUs and options, this means California taxes a portion of the income even after you've moved away — based on how many days you were a CA resident while vesting. If you leave California after the IPO S-1 is filed but before your RSUs finish vesting, California will still tax the portion earned during CA residency. Moving before the vesting period begins is the cleanest escape; moving partway through creates a complex multi-state calculation.

Pre-exit domicile change

For founders with substantial unvested equity (pre-IPO grants still on a 4-year vest), a domicile change to Nevada, Florida, Texas, Wyoming, or South Dakota before the equity vesting period begins can eliminate state income tax on the entire vesting period — not just post-move vesting. The planning window closes once CA residency has accrued during any of the vesting period.

CA's Franchise Tax Board uses an aggressive audit standard for residency departures of high-income taxpayers. See our detailed guide to state tax domicile change for UHNW families for the FTB "closest connections" standard, the 546-day safe harbor (narrowly construed), and the domicile checklist.

Post-lockup diversification

The moment lockup expires, you face a concentrated-stock problem: potentially $30M–$100M+ in a single security that you've held for years and can now finally sell. The tax cost of selling everything immediately at LTCG + NIIT + CA rates can be $20M–$35M on a $100M position. The tools for managing this tradeoff:

Systematic selling via 10b5-1

The most common approach. A pre-scheduled selling program set before lockup expiry allows diversification across many trading windows. Tax efficiency depends on holding periods — selling shares acquired pre-IPO at LTCG rates is much more efficient than selling recently vested RSUs at ordinary income rates.

Exchange funds

An exchange fund (§721 partnership contribution) allows you to contribute concentrated shares and receive a diversified basket of other contributors' shares after a 7-year lockup — with no recognition of gain at contribution. For founders with very long time horizons and deep concentration, exchange funds defer indefinitely. The pool includes other founders, executives, and family offices contributing their own concentrated positions. Minimum contribution typically $5M–$10M.

Prepaid variable forward (PVF)

A PVF lets you monetize up to 80–85% of a concentrated position today while deferring gain recognition for 2–3 years. You receive cash now; you deliver shares (or cash equivalent) at contract settlement. The IRS has accepted PVFs as tax-deferred under Rev. Rul. 2003-7 — subject to the §1259 constructive sale rule (you must retain meaningful upside potential at the ceiling to avoid acceleration). PVFs are especially useful when you need liquidity before LTCG holding periods are met.

Charitable strategies

Contributing appreciated stock directly to a donor-advised fund generates a deduction at full FMV with no capital gains recognition — permanently eliminating the embedded gain on donated shares. For founders with philanthropic intent, a DAF contribution in the IPO year (when income is at peak) produces the largest deduction against the largest income event. A charitable remainder trust (CRT) lets you contribute shares, receive an income stream for life, and defer gain recognition inside the trust.

Direct indexing as a tax offset

Once you've started selling post-IPO stock (generating capital gains), a direct indexing SMA in a separate account can harvest tax losses across hundreds of individual positions to offset those gains. A $10M direct indexing account generating 2–3% annual loss harvesting can offset $200K–$300K/year in capital gains from post-lockup sales — not a primary diversification tool but a meaningful tax drag reducer over time. See our direct indexing guide for mechanics and thresholds.

The fee-only advisor role at IPO

The IPO event touches six separate specialist domains simultaneously: equity compensation tax, estate planning, investment management, philanthropy, insurance (D&O exposure, excess liability for public company executives), and state tax/domicile. At most firms, these specialists operate in silos. The fee-only advisor coordinating them acts as quarterback:

• Sequences the pre-IPO gifting, GRAT establishment, and 10b5-1 plan setup so no action creates a problem for another (e.g., transferring shares to a GRAT must be coordinated with the company's insider trading policy and any lockup agreement terms)
• Models the full tax outcome across federal, California, and AMT on a multi-year basis — not just the current year
• Coordinates with your estate attorney on pre-IPO trust funding and the IDGT installment sale documentation
• Sets up the post-lockup diversification strategy before lockup expires, so you're not making decisions under time pressure in the middle of a volatile stock market

The fee-only structure matters here because the decisions made — which exchange fund, which PVF counterparty, how much to donate vs. sell — generate no commissions for a fee-only advisor. A wirehouse advisor or private banker may be influenced by which product generates the most revenue. At $30M+ IPO proceeds, that conflict is worth $1M+ in avoidable costs.
