Signing a buy-sell agreement feels like finishing the job. It is not. The paper only says who will buy a departing owner’s share. Buy-sell funding decides whether the money to complete that purchase actually exists on the day it is needed.
Too many co-owned U.S. businesses skip this step, and the result is predictable: families waiting on payments, surviving owners scrambling for loans, and partnerships that never recover. Here is how to fund a buyout the smart way, what each option really costs, and where the tax traps hide.
Key Takeaways
- Buy-sell funding is the cash plan that turns a signed agreement into a completed purchase.
- Life insurance is the most common source for death, but it does nothing for disability, retirement, or divorce.
- Your funding method should match your structure: cross-purchase, entity redemption, or hybrid.
- Coverage sized years ago is often too small, so revisit value and policy amounts every year.
- Premiums are generally not deductible, while death benefits are generally income tax free.
- The 2024 Connelly ruling changed the estate tax picture for company-owned policies, so review yours with a CPA and attorney.
What Is Buy-Sell Funding?
It is the plan for paying the purchase price when a triggering event forces a buyout. In short, it answers one question: where will the money come from?
A strong agreement can say who buys, what the price is, and when closing happens. None of that helps if the buyers cannot write a check. Think of buy-sell funding as the engine under the contract.
Why an Unfunded Agreement Fails
An unfunded agreement hands the departing owner, or their family, a legal right to sell and no cash to collect. A court can enforce a contract, but it cannot create money.
In practice, the surviving owners often borrow against the company, sell assets, or negotiate a long payout. That strains operations just when the business has lost a key person. The family waits.
Planning ahead flips the story. Good buy-sell funding gives everyone a predictable outcome at a moment when emotions run high.
Main Ways to Handle Buyout Funding
Life Insurance
This is the workhorse for death triggers. Each owner, or the company, holds a policy on the others. When an owner dies, the policy pays a lump sum, usually within weeks, and the buyers use it to purchase the share. Death benefits are generally free of income tax.
The downsides are real. Premiums are paid with after-tax dollars and continue for years. An owner with health problems may be uninsurable. Large age gaps mean younger owners pay more to insure older ones, and uneven ownership percentages can push costs onto the smaller owners.
Permanent policies build cash value that may help with a retirement or disability buyout. Term policies cost less, but coverage can end before the owner does. Also check the insurer’s financial strength rating now and then, because a policy is only as good as the company behind it.
Disability Buyout Insurance
Disability is harder to fund than death. The agreement should define what counts as disabled and how long the waiting period lasts. Disability buyout coverage is built for this job.
It is not the same as overhead expense coverage, which pays business bills. Confirm in writing which policy backs the agreement.
Cash Reserves and Sinking Funds
A sinking fund is a reserve the company builds through regular contributions. It works well for retirement and voluntary exits, where timing is fairly predictable.
The trade-off is opportunity cost. Cash parked for buyout funding is cash that cannot be used to grow the business.
Installment Notes
Here the buyer pays over several years. The agreement should set the interest rate, the payment schedule, and the security behind the note. It eases cash flow pressure, though the seller carries risk and may wait years for the full price.
Protect the seller with clear terms. Common safeguards include collateral or pledged shares, default and acceleration clauses that make the full balance due if payments stop, and an interest rate that meets the IRS minimum, known as the applicable federal rate.
Bank Loans
Borrowing can bridge a gap when insurance falls short. It adds debt and repayment risk, and lenders may ask for personal guarantees.
Key Person Insurance
This is a companion tool, not a substitute. It pays the company when a vital owner or employee is lost, helping cover lost revenue and replacement costs. It does not buy the departing owner’s shares.
A Layered Approach
Many owners combine sources: life insurance for death, disability coverage for illness, and a note or reserve for everything else. Funding a buy-sell agreement in layers covers more triggers with fewer gaps.
Funding Sources at a Glance
| Source | Best for | Main drawback |
| Life insurance | Death of an owner | After-tax premiums and insurability limits |
| Disability buyout insurance | Long-term disability | Strict definitions and waiting periods |
| Sinking fund or reserves | Retirement and planned exits | Ties up working capital |
| Installment note | Almost any trigger | Seller waits and carries credit risk |
| Bank loan | Filling a funding gap | Debt, repayment risk, possible guarantees |
| Key person insurance | Lost revenue (companion tool) | Does not pay for the departing share |
Match Your Funding to Your Structure
Your structure decides who owns the policies and who pays the premiums. Get that wrong and your buy-sell agreement funding can create tax problems you never planned for.
- Cross-purchase: each owner insures the others. Policy counts climb quickly, since four owners need twelve policies. Buyers also gain a higher tax basis in the shares they buy.
- Entity redemption: the company owns one policy per owner and uses the proceeds to buy back shares. It is simple to run, but the remaining owners do not get a basis step-up.
- Hybrid: the company gets the first option and the owners step in second. It is flexible, but it needs careful drafting so policy ownership still works.
If your business is an LLC or partnership, the same ideas apply to membership or partnership interests, though the tax rules differ.
A 2024 Supreme Court case, Connelly v. United States, put company-owned policies under the spotlight. The Court held that insurance money a company receives to redeem a deceased owner’s shares counts toward the company’s value for federal estate tax. The duty to redeem is not necessarily an offsetting debt.
The federal exemption is roughly $15 million per person in 2026, so many owners will never owe federal estate tax. But if your company value plus policy proceeds could approach that line, or your state taxes estates, ask your CPA about a cross-purchase setup or a separate insurance entity. Moving existing policies can trigger the transfer-for-value rule, so get advice first.
Converting a Redemption Plan to Cross-Purchase
If you decide to switch, the main task is moving the policies out of the company. That step has tax traps of its own.
A direct transfer to the owners can be treated as a taxable dividend or as compensation. A sale of each policy to the insured owner at its fair value avoids that, though it costs cash and requires the owner to stay insurable. Some groups instead use an insurance-only LLC to hold one policy per owner. Your attorney and CPA should choose the route.
Match Funding to Each Trigger
- Death: life insurance is the natural fit.
- Disability: disability buyout coverage, a reserve, or an installment note after a waiting period.
- Retirement or voluntary exit: installment payments, a sinking fund, or policy cash value.
- Divorce or bankruptcy: usually buyer financing or a note, since no insurance event occurs.
- Forced exit or deadlock: financing or notes, often with a longer payout schedule.
Buy-sell funding that covers only death leaves the more likely scenarios uncovered. Gaps in buyout funding tend to show up in disability, retirement, and divorce first.
When an Owner Is Uninsurable
Health problems or age can make an owner impossible to insure at a reasonable price. That does not mean the plan is dead.
Fallback options include higher coverage on the other owners, a dedicated reserve, or an installment note backed by the company. The agreement should spell out which fallback applies, so the family is not left guessing.
How Much Coverage Do You Need?
Right-sized buy-sell funding starts with a current, realistic value for each owner’s stake. Then match coverage to it. Eyeballing a number from years ago is the most common error.
Say two partners each own half of a dental lab. At signing, the company was worth $800,000, so each bought $400,000 of coverage. Today it is worth $2.4 million. A death now triggers a $1.2 million purchase, but the policy pays only $400,000. The $800,000 gap lands on the survivor or the family.
The fixes are simple. Get an independent valuation on a set schedule, check coverage every year, and write rules for shortfalls and surplus. If proceeds exceed the price, say who keeps the extra. If they fall short, say how the balance gets paid. Funding a buy-sell agreement without those rules just postpones the argument.
Sharing Premium Costs Fairly
Premiums rarely split evenly. Older owners cost more to insure, and larger owners need more coverage. In a cross-purchase plan, that can leave younger or smaller owners paying more than feels fair.
Many groups handle this with a formula that shares premiums by ownership percentage, or with bonuses from the company that help owners pay. Bonuses can raise tax questions, so have your CPA look at the numbers first.
Who Holds the Policies and Checks the Payments?
Policies sitting in a desk drawer tend to lapse unnoticed. Decide who holds them and who verifies that every premium was paid.
Some businesses ask their attorney, a trustee, or an escrow agent to keep the policies and review annual statements. When there are many owners, a trust or an insurance-only LLC can hold the policies, so one entity owns them instead of dozens of individuals. Put an annual proof-of-payment rule in the agreement.
When an Owner Leaves or a New Partner Joins
Funding is not set-and-forget. When an owner leaves, the departing owner can often buy the policy on their own life, and the others may keep or cancel the policies they hold on that person. Moving a policy the wrong way can trigger the transfer-for-value rule.
A new partner changes the math, too. In a cross-purchase plan, every new owner means new policies and updated coverage amounts. Amend the agreement and the funding together.
Legal Limits on Company-Funded Buyouts
A company cannot always repurchase an owner’s shares just because the agreement says so. Many state corporate laws restrict a corporation from buying back its own stock if the purchase would leave it unable to pay its debts as they come due.
Loan agreements can add limits as well. Some bank covenants restrict redemptions or distributions. Check both before relying on company cash for a buyout, and ask your attorney how your state treats LLC and partnership buyouts.
Tax Rules That Affect Buy-Sell Funding
- Premiums and proceeds: premiums are generally not deductible, and death benefits are generally income tax free.
- Group life insurance: usually a poor fit. Premiums are normally deductible, but not when the business is the beneficiary.
- Employer-owned policies: death benefits on employee policies issued after August 16, 2006 can be taxable unless an exception applies, so notice and consent rules matter.
- Basis: cross-purchase buyers get a stepped-up basis, while redemption buyers do not. A redemption that does not fully end the seller’s interest may be taxed as a dividend rather than a sale.
- Transfer-for-value: selling or moving an existing policy can make the proceeds taxable.
- Surrender gains: cashing out a policy can create taxable gain, including any outstanding loans.
- Estate inclusion: if the insured owner controls a policy, the proceeds can land in the taxable estate. An irrevocable life insurance trust can help.
- State rules: some states tax estates or inheritances and may not accept the agreement’s price as final.
Good tax advice needs the full picture: entity type, structure, ages, and estate plans. Bring in a CPA early.
Common Buy-Sell Funding Mistakes
Most failures in buy-sell agreement funding are boring and entirely preventable.
- Setting coverage once and never revisiting it.
- Funding death only and ignoring other triggers.
- Letting premiums lapse because nobody checks.
- Owning policies in the wrong name for the chosen structure.
- Using a term policy that expires before the owner retires.
- Overlooking an owner who can no longer qualify for insurance.
- Leaving out shortfall and surplus rules.
How to Set Up Buy-Sell Funding, Step by Step
- Get a current valuation of the business.
- Confirm your structure: cross-purchase, entity redemption, or hybrid.
- List every trigger and match each one to a funding source.
- Check insurability and get quotes for each owner.
- Decide who owns each policy, who pays premiums, who holds the policies, and who is the beneficiary.
- Write shortfall, surplus, and proof-of-payment rules into the agreement.
- Have your attorney, CPA, and insurance professional review everything.
- Revisit value and coverage every year and after any ownership change.
Frequently Asked Questions
What is buy-sell funding?
It is the money plan behind a buy-sell agreement. It identifies where the cash will come from when an owner dies, becomes disabled, retires, or leaves. Common sources include insurance, reserves, installment notes, and loans.
How is a buy-sell agreement funded?
Funding a buy-sell agreement usually starts with life insurance for death and disability coverage for illness. Retirement and voluntary exits are typically handled with installment payments or a sinking fund. Many owners mix several sources.
Who pays the premiums in buy-sell funding?
It depends on the structure. In a cross-purchase plan, each owner pays for the policies they hold on the others. In an entity plan, the company pays. Some companies give owners bonuses to cover premiums, which can raise tax questions.
Are buy-sell agreement premiums tax deductible?
Generally, no. Life insurance premiums paid to fund a buyout are usually not deductible, though death benefits are typically received income tax free. Your CPA can confirm how this applies to your situation.
What happens if a buy-sell agreement is not funded?
The agreement still exists, but the buyers must find the money elsewhere, often through loans, asset sales, or a long installment plan. That can delay payment to the family and strain the business.
Bottom Line
Buy-sell funding is what turns a good agreement into a working plan. Match your funding to your structure and to each trigger, size coverage to today’s value, and review it every year. Then sit down with an attorney, a CPA, and an insurance professional so your partners and your family never have to scramble.
