Pre-IPO Executive Financial Planning: The 12-Month Countdown

If you're a C-suite executive or senior officer at a late-stage private company approaching IPO, the 12 to 18 months before the offering are the most financially consequential window of your career. Decisions made here — which ISOs to exercise, whether to file an 83(b), whether to take partial liquidity in a tender offer, when to adopt a 10b5-1 plan — can mean the difference between $5M and $15M in after-tax wealth from the same equity position. Most of these decisions are irreversible once the window closes.

This guide is for executives at Series D and later-stage private companies who have meaningful equity positions and are within 12–18 months of a public offering. It covers the key decisions in order — from actions you need to take now, through post-IPO lockup planning.

Your pre-IPO equity inventory

Most executives at late-stage private companies hold a mix of instruments with very different tax profiles:

The most important decisions almost always center on the ISOs. They're the instrument where timing and elections can create or destroy millions in tax value — and where the 30-day 83(b) deadline creates hard irreversible cutoffs.

The ISO early exercise decision

At most startups, option agreements allow early exercise — you can exercise your options before they're fully vested. The shares you receive are subject to the company's repurchase right (at the original exercise price), which lapses as vesting occurs. You own the shares immediately; the company just has a right to buy them back if you leave before vesting.

Early exercise combined with an 83(b) election is worth considering when three conditions hold:

1. The 409A fair market value is close to your strike price. If you exercised 500,000 ISOs at $0.50 when the current 409A FMV is $0.60, the AMT preference item is $50,000 — manageable. If the 409A has risen to $8.00, that same exercise creates a $3.75M AMT preference item, likely triggering several hundred thousand dollars of AMT before you receive a dollar of cash.
2. You have cash to pay the exercise price. Early exercise on unvested shares is still an out-of-pocket purchase.
3. You believe in the company's value at IPO. You're taking on downside risk during the period the repurchase right is active — if you leave or the company fails, you may lose your investment.

The 409A clock matters

Private companies must obtain a 409A valuation at least annually — and more frequently when material events occur (new funding rounds, M&A interest, major financial milestones). In a company approaching IPO, 409A valuations tend to ratchet upward as each new funding round implies higher value. The window for low-spread early exercise typically closes 6–18 months before the IPO as the 409A catches up to the anticipated offering price.

If your company raised a Series E at a $3B valuation and the last 409A came in at $18/share, exercising a $2.00 ISO now creates a $16/share AMT preference item. Waiting for the IPO lockup to expire and exercising nothing in the meantime leaves you holding options that may expire — or forces a rushed post-IPO exercise with full ordinary income treatment for any NSOs.

The 83(b) election: 30-day hard deadline

If you exercise unvested ISOs through early exercise, you must file an 83(b) election within 30 calendar days of the exercise date to lock in your AMT and tax basis at FMV-at-exercise. If you miss the 30-day window, the election cannot be cured — each subsequent vesting event creates a new AMT preference item at that event's 409A FMV, eliminating the benefit of early exercise.¹

The election is straightforward: a one-page statement sent to the IRS service center for your region, postmarked within 30 days. You must also provide a copy to your employer. See Section 83(b) Election: Mechanics and Tax Math for the filing procedure and a sample statement.

Starting in 2024, the IRS introduced Form 15620 as an optional standardized 83(b) election form — you can use either that form or a written statement conforming to Treas. Reg. § 1.83-2. Either way, postmark is the deadline; electronic filing is not available for 83(b) elections.

QSBS: potentially $15M federal tax-free

If the company you've been working at qualifies as a Qualified Small Business (QSB) under IRC § 1202, the shares you acquire on ISO exercise may qualify as Qualified Small Business Stock (QSBS) — potentially sheltering up to $15M of gain from federal capital gains tax entirely.²

Post-OBBBA QSBS rules (stock issued after July 4, 2025)

• 3-year hold: 50% of gain excluded from federal tax
• 4-year hold: 75% excluded
• 5-year hold: 100% excluded — up to $15M of gain (or 10× adjusted basis, whichever is greater) per issuer
• Gross assets test: Company must have had ≤ $75M in aggregate gross assets at the time of stock issuance
• The $15M cap is indexed for inflation beginning in 2027

Pre-OBBBA stock (issued on or before July 4, 2025)

• Must hold for more than 5 years for 100% exclusion
• Maximum exclusion: $10M of gain (or 10× basis) per issuer
• Company gross assets must have been ≤ $50M at issuance

The implications are significant. An executive who early-exercised 1M ISOs at $0.20 in 2022 when the company had $40M in gross assets, holds those shares for 5 years, and sells at $14.00/share after the IPO lockup has a $13.8M gain. Under pre-OBBBA QSBS rules (stock issued in 2022), the full $10M exclusion applies, sheltering $10M of that gain from federal capital gains tax — saving roughly $2.38M in federal tax compared to LTCG treatment. Under the $14M baseline, most of the gain is sheltered.

Critical caveats: California does not conform to the federal QSBS exclusion — California treats the full gain as taxable income. Other states vary. Option shares only qualify as QSBS from the moment of exercise, not from the grant date — the holding period starts at exercise. The company must be a domestic C-corporation (partnerships and LLCs taxed as partnerships do not qualify). Verify with a tax advisor before building a plan around QSBS.

AMT cash flow planning: the pre-IPO crunch

If you exercise ISOs while the company is still private, you face a specific cash flow problem: you owe AMT in April of the following year, but you can't sell the shares to pay it (the company isn't public yet, and lockup may still be in effect after IPO). This "AMT crunch" has left executives insolvent — or forced early sales that triggered disqualifying dispositions and eliminated the LTCG advantage they were trying to capture.

2026 AMT parameters

• Exemption (single): $90,100 — phases out above $500,000 AMTI at $0.50 per dollar³
• Exemption (MFJ): $140,200 — phaseout begins at $1,000,000 AMTI
• AMT rates: 26% on AMTI below $244,500 above exemption; 28% above

Before exercising pre-IPO ISOs, calculate your projected AMT for the year — and verify you have enough liquid assets outside of the company shares to pay the bill. The AMT credit (Form 8801) allows you to recover AMT paid in a prior year against regular income tax in future years when regular tax exceeds AMT — but only if you have future years with large capital gains or other income that generates high regular tax. Do not assume the credit will recover the cash in the year you need it.

Tender offers: the partial liquidity decision

In the 12–24 months before IPO, late-stage companies frequently conduct tender offers — the company or an outside investor purchases shares from employees, giving insiders an opportunity to sell a portion of their holdings before the public offering. Participating provides real liquidity and reduces concentration risk; not participating preserves upside and may preserve QSBS eligibility.

The tax math on tender offer sales

Selling shares in a tender offer is a capital transaction. If the shares have been held long enough for long-term capital gains treatment (more than one year for ordinary shares; the ISO qualifying period for ISO shares), the gain is taxed at long-term rates — 15% or 20% federal plus 3.8% NIIT above the threshold.³

The complication for ISO holders: selling ISO shares in a tender offer before meeting both ISO holding periods (1 year from exercise and 2 years from grant) creates a disqualifying disposition. The spread as of the exercise date becomes ordinary income in the year of sale — taxed at up to 37% federal — rather than LTCG. If you haven't yet exercised and you exercise-and-sell as part of the tender offer, it's treated as ordinary income from the start (same as any cashless exercise).

For QSBS purposes, selling before the 5-year holding period (or 3 years for the 50% exclusion under post-OBBBA rules) forfeits the exclusion on the shares sold. Partial tender offer sales of QSBS shares sacrifice the largest-value tax shelter in the tax code for liquidity that may not be necessary if the IPO is imminent.

How to frame the decision

The rational framework: compare the after-tax value of selling in the tender offer vs. holding through IPO and lockup expiration. Key inputs:

• Tender offer price vs. expected IPO offering price vs. expected 6-month post-lockup price
• Tax cost of the tender offer sale (ordinary income vs. LTCG rate differential)
• Risk discount for the period between now and lockup expiration (market decline, company-specific risk)
• QSBS forfeiture cost if applicable (up to $3M+ of federal tax savings on a $15M gain)

Many executives at companies within 6 months of IPO find that the tender offer's risk-reduction value doesn't justify the tax cost and QSBS forfeiture, especially if they have other liquidity. For executives with concentrated, illiquid holdings representing 90%+ of net worth, even a tax-costly tender offer sale may be prudent risk management.

10b5-1 plan timing: adopt before you need it

Once your company is public, you're an affiliate subject to SEC Rule 144 volume restrictions and subject to blackout periods during quarterly earnings seasons. You cannot simply call your broker and sell shares whenever you want. The mechanism executives use to sell legally is a 10b5-1 trading plan.

The critical pre-IPO insight: you need to adopt the 10b5-1 plan before the lockup expires, not after. Under the December 2022 SEC amendments, officers and directors face a mandatory cooling-off period between plan adoption and the first trade — the longer of 90 days or the next quarterly earnings release, capped at 120 days.⁴ If your lockup expires in month 6 post-IPO and you want to start selling immediately, you need to adopt the plan before month 4 post-IPO (earlier if an earnings release falls in the gap).

The additional complication: during the lockup period, your company's counsel and underwriters may restrict when you can even adopt a new trading plan. Many lockup agreements prohibit trading and also restrict activities that could be construed as "preparing to trade." Work with your securities counsel to identify the earliest date you can legally adopt a plan. The practical answer for most executives: adopt the plan 4–5 months before lockup expiration, once counsel confirms the adoption window is open.

See 10b5-1 Plans for Executives and IPO Lockup Expiration Planning for the full mechanics of plan design and Rule 144 volume calculations.

NQDC at a pre-IPO company

If you have a non-qualified deferred compensation plan (NQDC) at your current company, the IPO and any post-IPO change of control trigger important 409A considerations:

• IPO itself is not a 409A distribution event. An IPO — the company becoming public — does not by itself permit a discretionary NQDC distribution under 409A. Your elections for distribution timing remain in place.
• A change-of-control is a 409A distribution trigger if you elected it when the plan was set up. The technical test: a change of control occurs under 409A when one person or group acquires more than 50% of total voting power, or more than 50% of total fair market value. For an IPO without a controlling shareholder, this may not be triggered. For an acquisition scenario, it likely is.
• Post-IPO acquisition: If your company is acquired in the 12–18 months after IPO — increasingly common — the 409A change-of-control distribution trigger may become active, creating a large ordinary income recognition event in a year when you also have IPO-related capital gains, RSU settlements, and 280G excise tax exposure. Planning the interaction of these events is complex and requires coordinated modeling well before the deal closes.

Pre-IPO 12-month planning checklist

The coordination problem

Pre-IPO planning isn't complicated because any single piece is hard — it's complicated because the decisions interact. Exercising ISOs creates AMT in the same year your W-2 is high. NQDC deferrals reduce current-year income in the same year you might want higher income to utilize the AMT credit. Tender offer sales may satisfy your liquidity needs but forfeit QSBS treatment. 10b5-1 plan adoption must coordinate with blackout periods, earnings dates, and lockup terms simultaneously.

For most executives, this means a one-time comprehensive planning engagement — not a routine annual review. The decisions made 12–18 months before IPO are worth planning carefully. Revisiting them after the S-1 is filed is often too late.
