Tax Planning Before You Sell Your Business — What Must Be Done Before the LOI

Every year, business owners complete transactions that cost them millions in unnecessary taxes — not because the strategies to reduce those taxes do not exist, but because they were not implemented before the sale process began. The letter of intent is not the starting point for tax planning. By then, many of the most powerful tools are unavailable.

The Timeline That Governs Everything

Once a letter of intent is signed — or once a sale is "practically certain" in the IRS view — the legal window for most pre-sale planning closes. Courts have disregarded pre-sale transfers made after an LOI was signed, after a handshake deal was reached, or after negotiations reached the point where the sale was essentially inevitable.

Minimum lead time: 60 to 90 days before any binding commitment. Preferred: 12 or more months.

Step 1: QSBS Analysis — Up to $15M Excluded Entirely

Section 1202 allows qualifying C corporation shareholders who have held original issue stock for at least 5 years to exclude up to $15 million of capital gains from federal income tax — entirely. Not at a lower rate. At zero.

Step 2: Pre-Sale Estate Planning

A SLAT, IDGT, or dynasty trust funded before the business is sold transfers equity at pre-sale value — permanently removing the transferred equity and all future appreciation from the taxable estate. After the sale, the window is gone: it is cash in your name, already taxed, representing no special estate planning opportunity.

This transfer must occur before any binding sale commitment. Courts apply the anticipatory assignment of income doctrine to transfers made after the sale is substantially certain — disregarding the trust entirely.

Step 3: Deal Structure — Asset Sale vs. Stock Sale

Buyers prefer asset sales (stepped-up basis, more depreciation). Sellers often prefer stock sales (lower capital gains rates, QSBS eligibility). The negotiation between these preferences is an economic trade-off — buyers should pay a premium for the asset deal that compensates the seller for the higher tax cost. We model both structures before you enter negotiations so you understand the numbers and can negotiate with full information.

Step 4: Personal Goodwill

In many service businesses, a significant portion of value is attributable to the personal relationships and reputation of the individual owner — not the corporate entity. This personal goodwill can be sold by the individual directly, converting what would have been a corporate-level event into a personal capital gain, often at a lower effective rate and without the double-taxation of a corporate asset sale.

Step 5: Installment Sale

Spreading gain recognition across multiple years can prevent income from being compressed into a single high-rate year, reduce NIIT exposure, and provide an ongoing income stream. Installment sales involve genuine credit risk — the buyer obligation must be secured — but for the right transaction structure, the after-tax economics are significantly better than a lump-sum sale.
