Transcript
- Lucas: You close the sale of your business. You get the wire transfer. You think you're done. Then, eighteen months later, you get a letter from the buyer saying the IRS just audited a tax position you took before closing, and they want you to cover the tax, penalties, and interest. The letter cites your purchase agreement — specifically the tax indemnity clause. Luna: And that clause probably says you're on the hook for any tax liability that arises from a pre-closing period, regardless of when the audit happens. Lucas: Exactly. That's the tax indemnity trap. It's one of the most commonly overlooked provisions in middle-market M&A, because sellers focus on price, earnouts, and working capital adjustments. But the tax indemnity can wipe out a significant chunk of your proceeds years after closing. Luna: So walk me through a real example. How does this actually play out? Lucas: I'll use a deal I saw in 2023. A software company based in Austin was acquired by a larger strategic buyer for $40 million. The seller was a founder who had built the company over fifteen years. The purchase agreement included a standard-looking tax indemnity clause — the seller would indemnify the buyer for any taxes arising from periods before closing. Luna: Standard. But the trap was in the details? Lucas: Right. The founder had taken advantage of the Research and Development tax credit under Section 41 of the Internal Revenue Code. He had claimed about $1.8 million in credits over the three years before the sale. The IRS allows that, but the documentation requirements are strict. The buyer's tax team flagged it during due diligence but didn't push for an adjustment. They just left the indemnity clause broad. Luna: So the buyer was essentially protected if the IRS ever challenged those credits. Lucas: Exactly. Fourteen months after closing, the IRS audited the founder's pre-closing tax returns. They disallowed $1.2 million of the R&D credits, plus added penalties and interest. Total came to about $1.6 million. But here's the kicker — the indemnity clause also covered any 'tax benefit' the buyer had received from the credits. Since the buyer had used those credits to reduce their own tax liability post-closing, the IRS clawed that back too, plus interest. The buyer demanded the seller cover the full $3.2 million. Luna: Wait — the buyer actually got a benefit from the credits, then the seller had to repay that benefit plus penalties? That's double jeopardy. Lucas: That's exactly how the clause was drafted. The founder's attorney hadn't negotiated a 'tax gross-up' or a 'diminution of tax benefits' limitation. The clause said the seller indemnifies for 'any tax liability attributable to a pre-closing period,' without carving out the buyer's own use of the credits. So the buyer was made whole three times: they got the audit refund from the IRS, they got the indemnity payment from the seller, and they still retained the economic benefit of the credits they had already used. Luna: That sounds like something a court would throw out as unjust enrichment. Lucas: You'd think so. But the Delaware courts have generally upheld clear contractual language in M&A agreements. In a 2019 case — 'Cigna v. Prudential' — the court enforced a similar indemnity clause even though it resulted in a double recovery for the buyer. The reasoning was that sophisticated parties agreed to the language, and the court won't rewrite the deal. So the founder had to pay. Luna: What could that founder have done to protect himself? Lucas: Three things. First, negotiate a 'tax gross-up' clause that caps the seller's liability to the net after-tax cost to the buyer. Second, limit the indemnity to 'final determinations' only — meaning the IRS must issue a final assessment, not just a preliminary notice. Third, and most important, include a 'diminution of tax benefits' provision that reduces the indemnity by any tax benefit the buyer actually realized from the disputed item. Luna: So you're saying the seller should pay only if the buyer actually suffered a net economic loss. Lucas: Precisely. And that's a fair outcome. The tax indemnity is meant to make the buyer whole, not give them a windfall. But without those provisions, the default language in most law firm templates gives the buyer exactly that windfall. Luna: I've also seen tax indemnity clauses that survive for the full statute of limitations — which in tax can be six years or more if the IRS suspects fraud. That's a long tail of exposure. Lucas: Right. The survival period is another trap. Many sellers assume indemnities expire after twelve or eighteen months, like general indemnities do. But tax indemnities often survive until the statute of limitations on the relevant tax returns runs out. That can be three years for most items, six years for substantial omissions, and unlimited if fraud is alleged. So you could be looking at a potential liability for half a decade or more. Luna: And the buyer can simply wait and see if an audit happens. They have no incentive to negotiate a shorter survival period. Lucas: Exactly. So a seller should push for a survival period tied to the expiration of the statute of limitations for the tax returns they prepared, but with a hard cap — say, five years max. And they should demand that the buyer must notify them of any claim within a reasonable time after the buyer becomes aware of it, otherwise the indemnity is waived. Luna: Let me ask you this — what about tax indemnity baskets and caps? Do those apply? Lucas: They can, but they're often negotiated separately from the general indemnity. Many buyers will insist that the tax indemnity has no basket — meaning the seller is liable for the first dollar of tax loss. Or they'll demand a very low basket, like $10,000. And the cap is often set at the full purchase price. That's terrifying for a seller. I've seen deals where the tax indemnity cap was 100% of the purchase price, even when the general indemnity cap was 10%. Luna: So the seller could end up giving back the entire sale proceeds because of a tax issue they thought was resolved. Lucas: Worse. The tax indemnity usually covers penalties and interest, which can exceed the original tax. So the seller could owe more than they received. That's why sellers need to treat the tax indemnity as a separate negotiation, not just a boilerplate clause. Luna: What about representations and warranties insurance? Does that cover tax indemnities? Lucas: Generally, no. Reps and warranties insurance specifically excludes tax indemnities. The policy will cover breaches of tax reps — like representations that the company filed all required tax returns — but it won't cover the tax indemnity clause itself. That's a contractual obligation, not a rep breach. So sellers often pay for R&W insurance thinking they're covered, but the tax indemnity is still a gaping hole. Luna: That's a critical point. So what's the single best protection a seller can get? Lucas: A clean tax opinion from a reputable tax firm covering the key tax positions taken pre-closing. That opinion doesn't guarantee the IRS will agree, but it establishes a reasonable basis. Then, during negotiation, the seller can point to that opinion and argue that the tax indemnity should be limited to situations where the buyer's own tax advisors confirm the position was unreasonable. That shifts the risk from 'any audit' to 'negligent or fraudulent positions.' Luna: That's a smart framing. It turns the indemnity from a strict liability into a fault-based one. Lucas: Exactly. And it forces the buyer to engage with the substance of the tax position rather than just relying on the blank check of the indemnity clause. I've seen that approach work in several deals over the past year. Luna: So for a founder listening right now who's considering selling their business in the next year or two, what's the one thing they should do today? Lucas: Get a tax audit readiness review. Have a tax firm go through your last three years of returns and identify any positions that could be challenged. Then you have time to fix documentation issues or, in some cases, file amended returns before you enter a sale process. That preemptive work can save you millions. Luna: And when you're in the deal, bring a tax specialist to the negotiation table, not just your corporate lawyer. Lucas: Absolutely. The corporate lawyer knows the indemnity language, but the tax lawyer knows the substance behind it. You need both. Luna: This episode was the kind of deep dive that actually moves the needle for someone going through an exit. If it moved yours, you know where to find us. Lucas: Yeah. If today's conversation was worth a coffee to you, the link is buy me a coffee dot com slash fexingo. That's buy me a coffee dot com slash fexingo. Keeps the show ad-free and independent. Luna: And we don't sell ads, so listener support is what keeps us going. Appreciate it. Lucas: Alright. Back to the trap. One last thing I want to flag: the 'tax sharing' or 'tax allocation' clause. This is another subtle danger. Some purchase agreements include a clause that says the seller must cooperate with the buyer in contesting any tax audit. But that cooperation clause can be used to force the seller to pay for the buyer's legal fees in the audit, even if the seller is not liable. So read that clause carefully too. Luna: So the cooperation clause can become an indemnity in disguise. Lucas: Exactly. Cap the cooperation costs. Make the buyer bear their own legal fees unless the seller is actually found liable. And define 'reasonable cooperation' so you're not expected to fly across the country every month for audit meetings. Luna: Good advice. So the takeaway: tax indemnity clauses are not boilerplate. They are a separate negotiation requiring specific expertise. Lucas: And they can be the difference between a successful exit and a painful post-closing surprise. Next episode, we'll look at the 'non-compete tail' trap — which is another one that often gets signed without a second read. Luna: Looking forward to it. Until then.
