How to structure your exit for maximum after-tax proceeds, from stock sales and QSBS exclusions to ESOPs and family succession
The exit is where decades of business building are converted into personal wealth. For C corporation owners, the way the exit is structured can mean the difference between keeping 60 cents on every dollar of gain or keeping 90 cents. The Internal Revenue Code provides several powerful provisions that, when planned for in advance, can dramatically reduce the tax cost of selling or transitioning a C corporation. This chapter covers the critical exit planning tools available to C corporation owners, from stock and asset sale structures to QSBS exclusions, ESOP transactions, and family succession strategies.
When a C corporation is sold, the transaction can be structured as either a stock sale (the buyer purchases the shareholder's stock) or an asset sale (the corporation sells its assets directly). The tax consequences for each party are dramatically different.
In a stock sale, the shareholder sells their shares directly to the buyer. The gain is the difference between the sale price and the shareholder's tax basis in the stock. This gain is taxed at long-term capital gains rates (up to 20% plus 3.8% NIIT = 23.8%) if the stock has been held for more than one year.
There is only one level of tax. The corporation does not recognize any gain because its assets remain inside the entity. The shareholder receives the proceeds and pays capital gains tax once.
Example: A shareholder sells stock with a $500,000 basis for $5,000,000:
In an asset sale, the C corporation sells its individual assets (equipment, inventory, goodwill, customer lists, real estate). The buyer receives a stepped-up cost basis in each asset, allowing them to depreciate and amortize the purchase price. This makes asset sales highly attractive to buyers.
For the seller, however, asset sales create double taxation. The corporation recognizes gain on the sale of its assets and pays 21% corporate tax. The remaining proceeds are distributed to the shareholder as a liquidating distribution, taxed at capital gains rates of up to 23.8%.
Example: The same $5,000,000 sale as an asset sale, with $1,500,000 in aggregate asset basis:
The difference: the stock sale leaves the seller with $3,929,000 after tax. The asset sale leaves the seller with $3,368,930. That is $560,070 more in the seller's pocket from the stock sale structure.
IRC Section 338(h)(10) offers a compromise. It allows a stock sale to be treated as an asset sale for tax purposes. The buyer acquires the stock but both parties elect to treat the transaction as if the corporation sold all its assets and liquidated. The buyer gets the stepped-up basis they want, and the seller accepts the double-tax consequences of an asset sale.
Why would a seller agree to this? Because the buyer will typically pay a premium for the stepped-up basis. If the buyer offers $5,500,000 with a 338(h)(10) election versus $5,000,000 for a straight stock purchase, the seller may net more after tax despite the double taxation. The economics depend on the specific numbers, and modeling both scenarios is essential before making this election.
IRC Section 1202 allows shareholders of qualifying C corporations to exclude up to $10,000,000 (or 10 times the adjusted basis of the stock, whichever is greater) in capital gains from the sale of Qualified Small Business Stock (QSBS). If fully applicable, this means a shareholder could sell $10,000,000 in stock completely tax-free at the federal level.
The five-year clock is absolute. If a shareholder sells stock at four years and 11 months, no QSBS exclusion is available. For business owners approaching a sale, extending the holding period by even a few months can save millions in taxes.
Example: A founder holds QSBS stock purchased for $200,000 and receives a $8,000,000 offer at the four-year mark. If the founder sells immediately, the $7,800,000 gain is taxed at 23.8%, resulting in $1,856,400 in federal tax. If the founder waits 12 months to sell at year five (assuming the same price), the entire $7,800,000 gain is excluded from federal tax. That 12-month delay saves $1,856,400.
The $10,000,000 exclusion is per-taxpayer. A married couple can each exclude $10,000,000 if each holds stock independently. Additionally, gifting QSBS stock to family members (who are each separate taxpayers) before the sale can multiply the exclusion. A founder who gifts QSBS stock to four adult children and their spouses could potentially access $10,000,000 x 10 taxpayers = $100,000,000 in excluded gains. The gift recipient inherits the donor's holding period and basis, so the five-year requirement and original issuance rules carry over.
Under IRC Section 453, a seller who receives payments over time (an installment note) recognizes gain proportionally as payments are received. This is particularly useful for retirement and exit planning because it spreads the tax liability across multiple years.
For C corporation stock sales, installment treatment allows the seller to defer recognition of the capital gain. If a $10,000,000 stock sale is structured with $2,000,000 per year over five years, the seller recognizes only $2,000,000 in gross proceeds each year, reporting gain ratably. This can keep the seller in lower tax brackets and defer the 3.8% NIIT on portions of the gain.
Important limitation: installment treatment is not available for assets sold at a loss, for dealer property (inventory), or for publicly traded stock. It applies to stock of private C corporations, making it a natural fit for closely held business sales.
When a C corporation shareholder dies, the estate may owe federal estate tax. IRC Section 303 allows the corporation to redeem stock from the estate to pay estate taxes and funeral and administration expenses, with the redemption treated as a sale or exchange (capital gains treatment) rather than a dividend.
Without Section 303, a stock redemption could be treated as an ordinary dividend under IRC Section 302, resulting in higher taxes. Section 303 provides a safe harbor for redemptions that do not exceed the sum of estate taxes plus funeral and administration expenses, provided the C corporation stock constitutes more than 35% of the decedent's adjusted gross estate.
This is a powerful tool for estate planning in closely held C corporations. The estate receives cash from the corporation to pay taxes, and the redemption is taxed at capital gains rates on the difference between the redemption price and the stepped-up basis (which is often minimal due to the Section 1014 step-up at death).
An Employee Stock Ownership Plan (ESOP) is a qualified retirement plan that invests primarily in employer stock. For C corporation owners, selling to an ESOP offers several unique advantages:
IRC Section 1042 allows a shareholder who sells C corporation stock to an ESOP to defer capital gains tax by reinvesting the proceeds in qualified replacement property (stocks and bonds of domestic operating companies) within 12 months. The gain is deferred until the replacement property is sold. If the shareholder holds the replacement property until death, the stepped-up basis under Section 1014 eliminates the deferred gain entirely.
Requirements for Section 1042 treatment:
The C corporation can deduct contributions made to the ESOP, including both principal and interest on loans used to finance the stock purchase. If the ESOP borrows $5,000,000 to buy the owner's stock, the corporation makes annual contributions to the ESOP to repay the loan, and those contributions are fully deductible. This creates a significant cash flow advantage: the corporation is effectively using pre-tax dollars to fund the acquisition.
ESOPs involve substantial administrative costs, annual valuation requirements, and fiduciary obligations under ERISA. They are most practical for companies with at least 20 employees and annual revenue above $5,000,000. The selling owner must also weigh the requirement that the ESOP hold at least 30% of the company, which means giving up meaningful equity to employees.
For multi-owner C corporations, buy-sell agreements determine what happens to a departing owner's stock. When funded with life insurance, these agreements provide liquidity to purchase a deceased owner's stock without draining the corporation's operating capital.
In a cross-purchase agreement, the remaining shareholders personally buy the departing owner's stock. Each purchasing shareholder's basis in the acquired stock equals the purchase price. Life insurance policies are owned by the individual shareholders.
In an entity redemption agreement, the corporation itself buys back the departing owner's stock. The corporation owns the life insurance policies and uses the proceeds to fund the redemption. However, the remaining shareholders do not receive a basis step-up in their existing shares (a significant drawback for future exits).
For C corporations with more than two owners, hybrid arrangements or LLC-owned policies can simplify the logistics while preserving favorable tax treatment.
Transferring a C corporation to the next generation involves both tax planning and business continuity considerations. Common strategies include:
Using the annual gift tax exclusion ($18,000 per recipient in 2024) and the lifetime gift tax exemption ($13.61 million in 2024), owners can gradually transfer stock to family members. Valuation discounts for minority interests and lack of marketability can reduce the gift tax value of the transferred shares by 20-40%.
Selling C corporation stock to an IDGT in exchange for an installment note is a sophisticated estate planning technique. The trust is structured so that the grantor is treated as the owner for income tax purposes (so the sale is disregarded for income tax) but the trust assets are outside the grantor's estate for estate tax purposes. This effectively transfers future appreciation out of the estate at no gift or income tax cost.
C corporation stock can be contributed to a family limited partnership (FLP), with the business owner retaining the general partnership interest and gifting limited partnership interests to family members. The limited partnership interests are eligible for valuation discounts, reducing the transfer tax cost.
The most tax-efficient exit strategy depends on numerous factors specific to each situation. Key variables include:
