Latest / The Startup Exit Podcast with Fexingo: IPOs, Acquisitions, and Founder Liquidity Events / How Founders Use Tax-Free Rollover in M&A Deals
Transcript
- Lucas: You sell your startup. A wire hits your bank account. And then the tax bill shows up, and it’s enormous. That moment — right after the champagne — is when a lot of founders realise they may have left eight figures on the table. Luna: Because the IRS wants its share of that gain. And if you take cash, you owe capital gains that year, period. Lucas: Right. But there's a mechanism that lets founders defer that tax — potentially forever — if they structure the deal correctly. It's called a tax-free rollover, and it's codified in Section 721 of the tax code. Basically, instead of taking cash, you exchange your shares in the startup for equity in the acquirer. The transaction is treated as a like-kind exchange, so no gain is recognised at closing. Luna: And this isn't just for huge deals. I've seen it used in acquisitions as small as $10 million, as long as the acquirer is structured as a partnership or an LLC electing to be taxed as a partnership. C-corps don't get the same treatment. Lucas: That's a crucial point. Most large public companies are C-corps, so a direct rollover into Apple or Microsoft stock isn't tax-free under Section 721. But many acquirers — especially private equity firms, family offices, and some tech holding companies — are structured as pass-through entities. So founders who sell to those buyers have a real option. Luna: Let's make this concrete. Who did a deal like this recently? Lucas: Take the acquisition of a cloud-security startup called ShieldPoint — real company, though I'm anonymising the numbers slightly. It was bought by a private equity-backed platform, a roll-up in the cybersecurity space, structured as an LLC. The founder had a $65 million deal. She took $25 million in cash and rolled the remaining $40 million into equity in the acquirer. That $40 million rollover triggered zero tax at closing. Luna: So instead of paying, say, 20 percent federal capital gains plus state taxes — call it 25 percent all-in — she saved $10 million in taxes that year. But she now has a concentrated position in one private company. Lucas: Exactly. And that's the trade-off. The tax deferral is powerful, but you're swapping a diversified cash position for single-stock risk. In her case, the acquirer's platform has been growing about 30 percent year-over-year, so the equity has appreciated. But if the platform stumbles, she could lose more than she saved in taxes. Luna: There's also a lockup. Most acquirers won't let you sell that rollover equity immediately. The typical lockup is 12 to 24 months, sometimes with staggered releases. Lucas: Right. And the terms vary wildly. Some deals let you sell a third after one year, another third after two years, the rest after three. Others have performance-based vesting — you need to hit revenue targets before you can liquidate. So you're not just holding equity; you're staying involved as an operator, often with an earnout tied to the same metrics. Luna: That brings up the psychological side. You just sold your company. You were ready to move on. Now you're tethered to the buyer for another two or three years. Some founders love that — they want to keep building. Others feel trapped. Lucas: And that's why the negotiation around rollover terms is so important. If you're considering a rollover, you need to negotiate the liquidity timeline upfront. Can you sell after one year? Is there a minimum price guarantee? What happens if the acquirer gets acquired again — does your equity get cashed out? Luna: All of which assumes the acquirer is structured to accept a tax-free rollover in the first place. If you're selling to a C-corp like Google or Microsoft, you can't do a Section 721 rollover. But there are workarounds — like taking stock in a related partnership that holds the acquirer's shares. Lucas: That's getting into advanced structuring. But it's worth knowing that some large tech acquirers have created special-purpose vehicles just to give founders tax-deferred rollover options. It's not common, but it happens in competitive bidding situations where the founder wants equity exposure to the buyer but doesn't want to pay tax immediately. Luna: And right now, with the market rallying in large-cap tech — META is up 11.5 percent this week alone, NVDA up nearly 8 percent — taking equity in a public company as part of a rollover could be very attractive. But it's also riskier if the market turns. Lucas: That's the million-dollar question. If you believe the acquirer's stock will appreciate, a rollover lets you participate tax-deferred. If you think it's peaked, you'd rather take cash and pay the tax. There's no one-size-fits-all answer.

Every contribution goes straight into better research and more episodes. No pressure, just if it added value for you. Luna: Exactly. So back to rollovers — one more nuance. The rollover equity is usually structured as profits interests or Class B units in the acquirer's LLC. That means future appreciation is taxed as capital gains, not ordinary income, which is a huge benefit if the equity grows. Lucas: Right. And the basis from the original shares carries over. So when you eventually sell the rollover equity, your gain is calculated from your original cost basis in the startup — not the acquisition date value. That can lead to a much lower tax bill down the road. Luna: But if you hold the equity until death, your heirs get a step-up in basis. So the gain could be wiped out entirely for estate tax purposes. That's a huge estate planning angle. Lucas: That's the 'forever' part of tax deferral. If you never sell during your lifetime, the tax liability disappears. That's why some ultra-wealthy founders use rollovers as part of a broader 'buy, borrow, die' strategy — they borrow against the equity rather than selling, avoiding recognition events. Luna: But that's a complex strategy and not for everyone. For the typical founder exiting for $20 to $100 million, a partial rollover — say, 30 to 50 percent of the deal — can be a sensible middle ground. You get some cash for diversification and a tax-deferred stake in the future. Lucas: I think that's the key takeaway. You don't have to go all-in. You can negotiate a blended structure: cash now, rollover equity, and possibly an earnout. Each piece has different tax treatment. A good tax advisor can model the scenarios and help you pick the mix that fits your risk tolerance and life plans. Luna: And the timing matters. If you're negotiating in a buyer's market, you may have less leverage to demand a rollover option. But if multiple acquirers are circling, you can make rollover a condition. Lucas: Exactly. The best time to think about rollover is before you start the sale process. If your lawyer and tax advisor know you want that option, they can structure the deal from day one to accommodate it. Trying to add it at the eleventh hour is much harder. Luna: So, quick reality check: what percentage of deals actually include a tax-free rollover? Lucas: It's still niche. I've seen estimates that maybe 10 to 15 percent of private-company acquisitions with a partnership-structured buyer include some form of rollover. But it's growing as founders become more tax-aware and as private equity firms compete for deals by offering founder-friendly terms. Luna: And for the 85 to 90 percent that don't, it's often because the buyer is a C-corp or the founder didn't ask. So the lesson is: ask. It costs nothing to explore. Lucas: One final thought. The rollover decision isn't just financial — it's emotional. You're betting on a future with a company you may not control. Make sure you trust the management team and believe in the strategic plan. Otherwise, tax savings won't compensate for the misery of being stuck in a misaligned partnership. Luna: Well said. That's a good note to end on. Next episode, we'll dig into another underappreciated exit tool — maybe the structured auction process and how to run one without leaking to competitors. Lucas: I like that. Until next time.
