What Is an Earnout in a Business Sale? A Home Services Owner’s Guide

An earnout is a deal structure where a portion of the purchase price is contingent on the business achieving certain performance targets after the sale closes. Instead of receiving the full purchase price at closing, the seller gets a base payment upfront and additional payments over one to three years if the business hits agreed-upon revenue, EBITDA, or other metrics. In home services M&A, earnouts are far more common than first-time sellers expect — and they shift meaningful risk from the buyer back to the seller.

For owners considering a sale, understanding how earnouts in a business sale actually work — including the typical structures, tax treatment, and protective clauses to negotiate — is the difference between collecting the headline number on the term sheet and watching a third of the deal value evaporate over the next two years.

How Earnouts Work

In a typical home services earnout, the buyer might offer a total purchase price of $4M structured as $3M at close and $1M in earnout payments tied to the business maintaining at least 90 percent of its trailing EBITDA over the next two years. If the business hits the targets, the seller collects the full $4M. If it does not, the seller gets less — sometimes much less.

The earnout payment can be structured as all-or-nothing (hit the threshold or get zero), pro-rata (you get a percentage of the earnout based on what percentage of the target you hit), or tiered (you get partial payment at 80% of target, full payment at 100%, and bonus payment at 120%). The structure matters enormously to expected value.

Earnouts are more common in home services deals than many sellers expect because the industry has characteristics that buyers want to insure against: owner concentration, customer concentration, and EBITDA that often depends on operational practices the new owner may not preserve. Buyers use earnouts to bridge the gap between what the seller thinks the business is worth and what the buyer is willing to pay with certainty.

When Buyers Push for Earnouts

The most common scenarios include owner-dependent businesses where the buyer is concerned that revenue will decline after the owner departs, businesses with concentrated customer relationships where retention is uncertain, companies showing recent growth that the buyer is not confident will continue, and situations where the quality of earnings review raised questions about the sustainability of current EBITDA.

In all of these cases, the earnout shifts risk from the buyer to the seller. The seller is betting that the business will continue performing. The buyer is protecting their downside if it does not. This dynamic is especially pronounced in private equity transactions, where PE buyers underwrite deals to specific return thresholds and use earnouts to protect their model if the underlying performance softens.

Typical Earnout Structures in Home Services M&A

While every deal is negotiated separately, certain patterns repeat across home services transactions:

The structure also depends on whether the buyer is a strategic acquirer (often more flexible, longer time horizon) or a financial buyer like a PE firm or aggregator (typically more rigid, focused on specific return metrics tied to their investment thesis).

The Tax Treatment of Earnouts

One of the most overlooked aspects of earnouts is how they get taxed. Earnout payments generally qualify as installment sale treatment under IRS Publication 537, which means the seller recognizes capital gains as the earnout is received rather than at closing. That can be helpful for managing the tax bill across multiple years.

However, the tax treatment depends on how the earnout is structured. If the earnout is treated as compensation for continued services (rather than additional purchase price), it gets taxed as ordinary income at much higher rates instead of long-term capital gains. This is a critical distinction. Buyers sometimes structure earnouts in ways that benefit them but disadvantage the seller from a tax perspective — for example, tying earnout payments to the seller continuing to work in the business in a way that makes the payments look like compensation.

The other tax wrinkle: if the maximum earnout is capped, the IRS uses the “maximum face value” rule to calculate the imputed interest portion of each payment, which means a portion of every earnout payment may be taxed as ordinary interest income rather than capital gains. Sellers with material earnouts should work with a CPA who specializes in M&A transactions to model the actual after-tax outcome before signing.

Protecting Yourself in Earnout Negotiations

Earnouts are inherently risky for sellers because after closing, the buyer controls the business — and their operational decisions directly affect whether earnout targets are met. A buyer who cuts marketing spend, raises prices too aggressively, restructures operations, or shifts work to a sister company can inadvertently (or deliberately) impair the earnout metrics.

Key protections to negotiate include:

Strong sellers walk into earnout negotiations with these protections in hand — and walk away if the buyer refuses to engage on the major ones. Weaker sellers accept boilerplate earnout language and lose money predictably.

How to Avoid Earnouts Entirely

The best way to avoid an unfavorable earnout is to address the underlying concerns before they arise. The fewer risks the buyer perceives, the less of the purchase price they will try to shift into contingent payments.

Sellers who decide whether to sell or keep the business often discover that the difference between a 100% cash deal and a 60/40 cash/earnout deal comes down to operational and financial work done in the 12 months before the sale.

Frequently Asked Questions About Earnouts

What percentage of a business sale is typically structured as an earnout?

In home services M&A, earnouts typically represent 10% to 30% of total deal value. Above 30% is a sign the buyer has significant concerns about the business; below 10% is often negotiable down to zero with the right preparation.

How long do earnouts usually last?

Two years is the most common earnout period for home services deals. One year is possible for cleaner businesses; three years is aggressive but happens when the buyer wants to lock in the owner’s continued involvement. Earnouts longer than three years are unusual.

Is an earnout taxed as ordinary income or capital gains?

Earnouts structured as additional purchase price generally qualify for capital gains treatment under the installment sale rules in IRS Publication 537. However, if the earnout is structured as compensation for continued services, it is taxed as ordinary income. The distinction is critical — and worth modeling with a CPA before signing.

What’s the difference between an earnout and a holdback?

An earnout ties contingent payments to future performance after closing. A holdback (or escrow holdback) sets aside a portion of the purchase price at closing to cover potential indemnification claims — typically for representations and warranties that turn out to be inaccurate. Holdbacks are about historical accuracy; earnouts are about future performance.

Can I negotiate out of an earnout?

Sometimes. If you can address the underlying concerns the buyer has — owner dependence, customer concentration, sustainability of EBITDA — you can often shrink or eliminate the earnout. Sellers with strong management teams, diversified customer bases, and clean financials face much less earnout pressure than those without.

What happens if the buyer changes the business after closing and the earnout fails?

This is exactly why operational covenants and acceleration clauses matter. Without them, the buyer can legally make changes that impair the earnout — and you have no recourse. With proper protections, the buyer is contractually constrained from taking certain actions, and disputed calculations get resolved through an independent third party.

Should the earnout be based on revenue or EBITDA?

Revenue is cleaner for sellers because it is harder for the buyer to manipulate post-closing. EBITDA gives the buyer more levers — addback definitions, expense categorizations, and accounting choices can all swing the number. If the earnout has to be EBITDA-based, the definition must be locked down in detail in the purchase agreement.

How common are earnouts in private equity acquisitions of home services companies?

Very common, especially for first-time PE acquisitions or platform deals. PE buyers underwrite to specific return thresholds and use earnouts to protect their model. Roll-up acquirers buying tuck-in deals also use earnouts frequently, often tied to customer retention through the integration period.

The Bottom Line on Earnouts

An earnout is not inherently bad — it can be the difference between getting a deal done and not getting a deal done. But it is also not free money. Every dollar of earnout is a dollar the seller is at risk of not collecting, taxed potentially less favorably than the cash at closing, and dependent on a buyer whose interests no longer fully align with the seller’s.

The owners who walk away with the most value are the ones who prepared the business well enough to negotiate from strength — minimizing earnouts where possible, structuring them carefully where they cannot be avoided, and pricing the risk into the headline number. Most of that preparation happens long before the LOI lands. For a fuller view of how the sale process works end to end, see our guide to selling a home services business.
