Buy-Sell Agreement Life Insurance Estate Tax: The Connelly Rule.
A company-owned policy that funds a buy-sell agreement is a corporate asset on the date of death, and the obligation to redeem the shares does not offset it. The Supreme Court settled that in 2024, and most shareholder agreements still have not caught up.

Two partners own a machine shop 50/50. The company buys a $5,000,000 policy on each of them, and the shareholder agreement says that when one dies, the company buys his shares back from his estate. Everyone understands the deal: the insurance funds the buyout, the survivor keeps the shop, the family gets cash. What nobody priced is that buy-sell agreement life insurance also raises the estate tax value of the shares it is buying, and the Supreme Court settled that against taxpayers in 2024.
What the Supreme Court held in Connelly.
Michael and Thomas Connelly owned Crown C Supply, a building supply company in St. Louis. Michael held 77.18% and Thomas held the rest. Their agreement gave the survivor an option to buy the deceased brother's shares, and if he declined, Crown had to redeem them. Crown carried $3,500,000 of life insurance on each brother to fund that. Michael died in 2013, Thomas declined the option, and Crown paid the estate $3,000,000 for the shares, a number the two sides settled on between themselves. The Form 706 reported that $3,000,000.
The IRS valued Crown at $6,860,000: $3,860,000 of operating value plus the $3,000,000 of insurance used for the redemption. That put Michael's 77.18% at $5,300,000 and produced $889,914 of additional estate tax. The estate paid it and sued for a refund, then lost on summary judgment in the Eastern District of Missouri, lost in the Eighth Circuit, and lost again before a unanimous Supreme Court.
The reasoning in the opinion is a hypothetical you can check on paper. A corporation holds $10,000,000 of cash and nothing else. A owns 80 shares and B owns 20, so each share is worth $100,000. Redeem B for $2,000,000 and A is left with a corporation worth $8,000,000 and 80 shares, still $100,000 a share. Nobody got poorer, so no willing buyer would discount the stock for the obligation.
Footnote 2 leaves one narrow door open: a redemption obligation can sometimes cut value, as when it forces a company to sell operating assets and lose future earning capacity. An insurance-funded redemption is the opposite. The cash arrives before the obligation comes due.
Why buy-sell agreement life insurance raises the estate tax on the very shares it buys.
Section 2031 values the gross estate at fair market value on the date of death, and Treas. Reg. §20.2031-2(f)(2) tells the appraiser to count nonoperating assets, including proceeds of life insurance payable to or for the benefit of the company. The proceeds are corporate cash at the moment of death. The redemption happens after.
This is not a §2042 problem. The decedent held no incidents of ownership in the policy (no control over it), so nothing enters the estate as insurance. It enters through the stock, as valuation, which is why owners who were careful to put the policy in the company's name still got hit.
The result is a gap the estate has to fund elsewhere. In the machine shop above, the estate reports $7,500,000 of stock and receives $5,000,000 for it. The §1014 step-up sets basis at that same $7,500,000, and a complete redemption of the estate's whole interest is an exchange under §302(b)(3), so the estate books a $2,500,000 capital loss. Most estates have no gains to absorb it and §1211(b) releases the rest at $3,000 a year, so the loss is decoration.
- Operating value of the corporation at the date of death
- $10,000,000
- Life insurance the corporation collects on the decedent
- $5,000,000
- Value of the corporation under §2031
- $15,000,000
- Decedent's 50% interest as the agreement priced it
- $5,000,000
- Decedent's 50% interest after Connelly
- $7,500,000
- Increase in the taxable estate
- $2,500,000
- Federal estate tax on the increase at 40%
- $1,000,000
- Cash the estate actually receives for the shares
- $5,000,000
Tax year 2026. Two equal shareholders, no valuation discounts applied, and the corporation's operating value assumed unchanged by the death. The decedent's other assets are assumed to absorb the $15,000,000 basic exclusion amount for 2026 under Rev. Proc. 2025-32, so the increase is taxed at the 40% top rate in IRC §2001(c). State estate tax is not shown.
Three ways to keep the proceeds out of the company.
- Cross-purchase. Each owner personally owns and is the beneficiary of a policy on the other. The proceeds never touch the corporation, so the company is still worth $10,000,000 and the estate's half is $5,000,000. The survivor also buys basis: he pays $5,000,000 for the shares and owns $5,000,000 of basis in them, which a redemption never gives him. The cost is policy count, which runs at n times n minus 1. Four owners means twelve policies.
- An insurance LLC taxed as a partnership. The owners form a separate LLC holding one policy per insured, and the operating agreement allocates each death benefit to the surviving members. That is twelve policies down to four. Moving existing policies in fits the transfer-for-value exception in §101(a)(2)(B) for a transfer to a partnership in which the insured is a partner, which a transfer to a co-shareholder does not. The allocation language has to push the proceeds past the decedent's own LLC interest, or Connelly follows you in.
- Keep the redemption and pay for the result. Size the coverage to fund the buyout plus the tax on the inflated value. Simplest, most expensive, and with one uninsurable owner it is sometimes the only one left.
Two documents that decide whether any of this holds up.
The agreement has to fix a price and the owners have to follow it. Under §2703(b) a buy-sell price binds the IRS only if the agreement is a bona fide business arrangement, is not a device to pass value to family for less than full consideration, and has arm's-length terms. The Connelly agreement failed before it reached that test. It set no price and no formula, only a mechanism calling for a new Certificate of Agreed Value each year or two appraisals instead. The brothers never executed one, and an undocumented price is one the IRS gets to ignore.
The policy has to clear §101(j). For employer-owned contracts issued after August 17, 2006, the death benefit above premiums paid is taxable income to the company unless the insured got written notice and gave written consent before the policy issued, and unless the company files Form 8925 each year. The exceptions in §101(j)(2) open only once §101(j)(4) is satisfied, and there is no carve-out for an owner insuring himself. Miss the consent and the same dollars are taxed twice, as corporate income and again inside the share value.
The $15,000,000 federal basic exclusion amount for 2026 convinces a lot of owners this is somebody else's problem. State estate tax disagrees. Oregon starts at $1,000,000 and does not index it, and Massachusetts starts at $2,000,000. A $2,500,000 swing in what the shares are worth is a live number in those states, and it is live federally for any owner whose company is most of an estate near the exemption. A GRAT moves future growth out and is worth pricing alongside the buy-sell.
