Planning Retirement Around an Expected IPO

A senior IC at a late-stage private company facing an IPO in the next 12-24 months has a compressed planning window. Retirement itself is an option, the IPO produces enough wealth to fund it. But the sequence of lockup expiration, tax-bracket optimization, Medicare enrollment (if age-relevant), and concentration reduction has to be thought through before the event rather than after.

This article walks through the common sequence for a senior IC in their late 50s or early 60s planning to retire within two years of an IPO. The goal is tax-efficient wealth preservation and a workable income stream that carries through to Social Security and Medicare.

The pre-IPO year

In the 12 months before IPO, you’re usually still working full-time. Income is heavy from base salary plus pre-IPO cash bonus. Double-trigger RSUs haven’t vested to taxable income yet (they require the liquidity event). This is the last year you’ll have normal W-2 but low taxable income.

Priorities in pre-IPO year:

• Max 401(k) ($23,500 elective + mega-backdoor to ~$46K after-tax if plan allows)
• Max HSA ($8,550 family, pre-tax payroll)
• Max IRA ($7,000 if eligible)
• Execute any 10b5-1 plan setup for post-lockup selling
• Review 83(b) election timing on any still-unexercised grants
• QSBS planning if you hold founder stock

Pre-IPO year is also the ideal year for any final Roth conversions. Once the IPO fires and RSUs vest, you’ll be in the 35-37% bracket for at least one year.

IPO year: the tax cliff

IPO triggers the second trigger on double-trigger RSUs. All previously-vested RSUs (first trigger: time-based vest) are now taxable as ordinary income under IRC §83. Your W-2 can balloon from $400K to $4M+ in one year.

The tax consequences:

• Federal top rate: 37% on income over $609K (2025 single) / $731K (married)
• FICA: 1.45% Medicare plus 0.9% additional Medicare tax (above $200K single / $250K married)
• California (if resident): 13.3% on income over $1M
• NIIT: 3.8% on investment income above thresholds (not on wages)

Withholding on RSU income at the IPO trigger is typically 22% federal supplemental rate (or 37% above $1M cumulative), which under-withholds for top earners. Expect a large Q1 estimated tax bill or owed tax at filing.

Planning moves in IPO year:

• DAF contribution of appreciated stock (30% AGI limit under IRC §170(b)(1)(C)(ii))
• QCD not yet available (requires age 70½)
• Maximize 401(k), HSA, FSA dependent care
• Consider CRT for large concentrated position if charitable intent exists
• Postpone any optional income (deferred comp exercise, IRA distributions)

Lockup expiration (usually 180 days post-IPO)

Lockup restricts insider selling for 180 days post-IPO, sometimes extended by greenshoe provisions or management agreements. Once lockup lifts, you can sell.

For a retiree-to-be, lockup release is when concentration-reduction starts. Options:

10b5-1 plan. Set up pre-lockup for automated selling at fixed intervals/prices. Cannot be modified once adopted (under current SEC rules after Rule 10b5-1 amendments in 2023). Provides insider-trading safe harbor.

Direct sale. Sell in open windows. Simple but requires manual execution and coordination with trading windows.

Collar or hedge. Lock in a range via options. Protects downside without triggering gains. Useful if you expect to sell in 6-12 months after lockup.

Exchange fund. Contribute $1M+ to an exchange fund for 7-year lock-in and diversified return. Deferred tax via §721 contribution.

The actual retirement year

Most retirees from an IPO-year company retire sometime in the year following IPO. The tax sequence typically looks like:

• Year 1 (IPO year): Peak income, ~$4M+ gross, retirement at year-end
• Year 2 (first retirement year): Lockup expires, selling begins, ordinary income drops to near zero, capital gains on RSU sales
• Year 3+: Steady-state retirement income

Year 2 is often a massive capital-gains year as positions are sold. Long-term capital gains (20% + 3.8% NIIT for top bracket) are lower than the ordinary rates of Year 1, but cumulative tax is still significant.

IRMAA timing for 60-year-old retirees

If retirement is in your early 60s with Medicare at 65, the IPO-year AGI affects Medicare premiums for potentially two years. A 2025 IPO with Medicare at 65 in 2027 means 2025 MAGI (high) drives 2027 Part B premium.

SSA-44 can reduce IRMAA upon retirement, citing “work stoppage” as a life-changing event. File the form with projected current-year MAGI.

For retirees 63+ in IPO year, the Medicare premium in their first two years of coverage is almost guaranteed to be top-tier without SSA-44 relief.

Bracket management across years

Spreading income across years where possible:

• Deferred comp payout schedules can sometimes be elected to extend over 5-10 years
• RSU selling schedule can be staged so long-term gains are spread instead of lumped
• Roth conversions saved for post-IPO low-income years
• Charitable contributions concentrated in IPO year for maximum AGI offset

A senior IC retiring with $6M of liquid stock might spread selling over 4-5 years, keeping each year’s long-term gains under the 20% threshold ($533K single / $600K married).

Asset location at retirement

Post-IPO liquidity flows into a taxable brokerage account. The tax-advantaged buckets (401(k), IRA, Roth) are separate. Allocation post-retirement:

• Taxable: recently-sold RSU proceeds, direct-indexed equity for ongoing loss harvesting, concentrated stock remaining
• 401(k): consider NUA election if employer stock inside; otherwise rollover to IRA
• Roth: highest-growth assets (broad-market equity)
• HSA: invested for long-horizon medical spending

This is the moment to reallocate. Pre-retirement allocations often assumed ongoing contributions and different risk tolerance. A retirement portfolio needs more bonds, more diversified equity, and less concentration.

Frequently asked

Should I exercise ISOs before IPO? Often yes, if you can afford the AMT hit and expect QSBS-qualifying gains. Pre-IPO exercise starts the long-term holding clock and potentially QSBS 5-year clock. Check QSBS eligibility under IRC §1202 for your grant.

What if lockup gets extended? Greenshoe extensions add 90 days. Management-imposed lockups can add more. Plan cash reserves to cover 12-18 months of living expenses without RSU liquidation.

How does pre-IPO secondary sales interact? Pre-IPO secondary sales at tender offers are taxable events. If you participated in a tender offer, the basis on those shares is stepped up. Remaining shares still have original basis. Track both sets separately.

What about relocating to a no-tax state before IPO? California trailing-nexus rules can keep RSU income sourced to California even after a move, depending on when grants were made and where workdays occurred. Consult a state tax specialist at least 12-24 months before the IPO.

Does the §6501 statute of limitations matter post-IPO? The normal three-year assessment window applies. For the IPO year with substantial complexity (QSBS, NUA, Roth conversions, large RSU gains), keep all records at least 7 years to handle any substantial-understatement extension under §6501(e).
