How to Calculate a Gross-Up in a Stock vs. AssetSale
Selling a business isn’t just about the number on the purchase agreement. The way the deal is set up can change the tax bill for both sides—sometimes by a lot. Buyers and sellers often prefer different approaches. One wants a stock sale, the other pushes for an asset sale. When neither is willing to budge, there’s a middle ground: a gross-up payment.
Stock Sale vs. Asset Sale – Why the Seller and Buyer See It Differently
In a stock sale, the buyer gets the entire company by purchasing the seller’s shares. Everything – contracts, licenses, assets—stays where it is. For the seller, the big win is usually the tax rate. Most of the gain is taxed as capital gains, which can mean less money going to the IRS and more staying in their pocket.
An asset sale works differently. The buyer picks which assets and liabilities to take. They also get to increase the tax basis of those assets, which means more depreciation and amortization deductions after the deal. That’s great for the buyer’s future tax savings but can leave the seller facing a much bigger tax bill, especially if the business is a C-corporation.
What a Gross-Up Payment Does
Think of a gross-up as a make-it-even adjustment. If the seller ends up owing more in taxes because the buyer insists on an asset sale, the gross-up payment covers that extra cost. The goal is simple: after taxes, the seller ends up with the same amount they would have received from a stock sale.
Figuring Out the Gross-Up
The math isn’t complicated in theory, but it’s easy to get wrong without the right tax experience. Here’s the general flow
- Work out what the seller’s tax bill would be in a stock sale.
- Do the same for the asset sale, factoring in corporate taxes, purchase price allocation, depreciation recapture, and shareholder-level taxes.
- The gap between the two numbers is the extra cost to the seller.
- Because the gross-up itself is taxable, increase the payment so the seller’s final after-tax number matches the stock sale result
. - Tricky issues like pass-through entity taxes, Qualified Small Business Stock, and state tax treatment of the gain can complicate the gross-up calculation, so an experienced M&A tax specialist is essential.
A Quick Example
Say the business sells for $10 million. In a stock sale, the seller’s tax bill might be $3 million, leaving $7 million in hand. In an asset sale, the tax bill could rise to $4 million. That’s a $1 million difference. But since the gross-up payment is also taxed, the buyer might need to add around $1.43 million to cover the gap.
Why It’s Worth Negotiating
A gross-up can break a deadlock. The buyer gets the tax benefits of an asset purchase, and the seller avoids losing out on net proceeds. Everyone walks away with a deal that works.
