How to buy out a business partner

Published October 25, 2026 · Facts checked as of October 2026

Short answer

To buy out a business partner: read your operating agreement or buy-sell agreement first, because it may already set the price method, timing and payment terms. Get an independent valuation of the business, agree price and terms, decide how to fund it (company cash, a loan such as an SBA 7(a) Owner Buyout, or payments to the departing partner over time), and document it with a purchase agreement, releases and updated ownership records.

Partner buyouts mix business with personal history, and often with frustration. The fastest way through is to let documents and independent numbers do the arguing. Not legal or tax advice; both partners need their own advisers.

Why buyouts go wrong

Most partner buyouts that turn ugly have one of three causes: no agreement on price method, so each partner hires an appraiser who agrees with them; mixing personal grievances into business terms, so every point becomes a referendum on the relationship; or leaving loose ends (guarantees, loans, customers) that keep the partners entangled after closing. The fix is the same in each case: rely on the written agreement where there is one, use a single independent valuation where there isn't, keep each partner's attorney focused on terms, and close every open item at once.

Steps

Read the agreements. Operating agreement, shareholder agreement or buy-sell: triggers, valuation method, payment terms, non-competes.
Get the numbers straight. Current financials, tax returns, debts and guarantees.
Value the share. Use the agreed method, or an independent appraiser. Settle questions such as discounts for a minority stake upfront.
Agree terms: price, cash at closing, any note to the departing partner, non-compete, release of guarantees.
Fund it: company cash, an SBA Owner Buyout loan, a bank loan, or installments.
Document: purchase agreement, resignation from roles, releases, updated ownership records and bank signatories.

Ways to pay a departing partner.

Worked example: three ways to pay a departing partner

Illustrative example, not a valuation or advice

Two partners own 50% each of a business with verified EBITDA of $500,000. An independent valuation, as the buy-sell agreement requires, concludes the whole business is worth $2,000,000, so the departing partner's half is $1,000,000 before any discounts the agreement allows. Option 1: a bank or SBA Owner Buyout loan of about $900,000 plus $100,000 of the remaining partner's cash. At an example 10.5% over 10 years, the loan costs about $145,700 a year. Coverage on $500,000 of EBITDA, after the remaining partner's market salary of $150,000 is already in the expenses: $500,000 ÷ $145,700 = 3.4. Option 2: the company pays the partner $250,000 at closing from cash and a $750,000 note over 7 years. Option 3: a combination, with a smaller loan and a smaller note. Each option moves risk between the remaining partner, the lender and the departing partner. The cheapest on paper isn't always the one the departing partner will accept.

SBA Owner Buyout points

At least one original owner must remain and guarantee the loan.
Individuals not employed by the business can only acquire less than 50% and can't become the largest owner in an Owner Buyout; otherwise it's processed as an Initial Acquisition.
Minimum DSC 1.25. Equity requirement is 10% of the purchase price, which the lender may reduce or eliminate if the business has enough liquidity and no negative net worth.
No QoE requirement for Owner Buyouts, but a business valuation is still required.
A selling owner who keeps under 20% must give a full guaranty for at least two years after final disbursement.

Questions to settle before you negotiate price

What does our operating or buy-sell agreement say about price, timing and payment?
Will the departing partner keep any role, or leave entirely?
Which loans, leases and credit lines carry their personal guarantee?
Are there loans between the company and either partner, or unpaid distributions?
Which customers and staff are closest to the departing partner?
How will we tell employees, customers and lenders?

Before you sign: the clean-up list

Release or replace the departing partner's personal guarantees on loans, leases and credit lines; lenders and landlords have to agree.
Update the operating agreement or shareholder records, bank signers and state filings as required.
Update the IRS responsible party with Form 8822-B if needed, and talk to your CPA about the tax treatment of the purchase and any partnership elections.
Get a non-compete and non-solicit from the departing partner where enforceable, and agree on how customers and staff are told.
Settle the partner's capital account, loans to or from the company, and final distributions in writing.
Agree who keeps company property, devices and accounts, and when access ends.

Valuation questions that cause partner disputes

Which date? The value on the trigger date, the last year-end or the closing date can differ a lot.
Which earnings? Partners often disagree about each other's pay and perks; agree a normalized figure.
Discounts or not? A minority share can be worth less per percent than a controlling one; the agreement should say whether discounts apply.
What's included? Cash, real estate held separately, partner loans and capital accounts.
Who chooses the appraiser, and what happens if partners disagree with the result.

Settling these in writing, ideally long before anyone wants out, is the best protection.

Red flags in partner buyouts

No buy-sell agreement, or one with a price formula nobody has updated in years.
Disputes about past distributions or expenses that will resurface in the price.
One partner controlling the books and the other relying on summaries.
Debt that only works with both partners' guarantees.
Using the buyout to settle personal disagreements instead of business terms.

Not legal or tax advice: each partner should have their own attorney.

Tax questions to settle before you agree terms

How the buyout is structured changes the tax result for both of you, and partners often discover this after the price is agreed. Ask your CPA about:

Whether the company redeems the partner's interest or you buy it personally. The tax treatment can differ for both sides.
For an LLC taxed as a partnership, how payments to the departing partner are characterised, and whether a step-up in the basis of company assets is available.
For an S corporation, how a redemption affects the remaining shareholders and whether the company has enough cash without breaching loan terms.
Whether any part of the payment is for a non-compete or consulting, which is taxed differently from a payment for the interest.
State taxes and any transfer taxes on real estate the company owns.

Agree the structure first, then negotiate the price, so both sides compare offers on an after-tax basis. This is general information, not tax advice.

Finally, tell the people who need to know in a planned order: lenders and the landlord first, since their consent may be needed, then key employees, then customers and suppliers. A buyout that leaks before it is signed can unsettle the people the business depends on.

Ask the lender early whether it will finance the buyout, and on what terms. SBA Owner Buyout loans have their own rules on equity and coverage, and a conventional lender may want the business's existing debt refinanced at the same time.

Frequently asked questions

How is a partner's share valued?

As your agreements specify. If they don't, partners often hire an independent appraiser. Questions like whether to apply minority discounts can change the number a lot, so agree the method first.

Can I use an SBA loan to buy out a partner?

Yes. Owner Buyouts are a change-of-ownership category under SOP 50 10 8.1, with a 1.25 minimum DSC. At least one original owner must remain and guarantee the loan, and the lender may reduce the 10% equity requirement if the business has sufficient liquidity.

What if we can't agree on price?

Buy-sell agreements often include a valuation mechanism or dispute process. Without one, mediation or each side hiring an appraiser are common routes.

Does the departing partner stay liable for business debts?

Often for debts they personally guaranteed, unless lenders release them. Address guarantees and releases in the buyout.

How is a partner's share valued in a buyout?

Usually as set by the buy-sell or operating agreement: a formula, an agreed annual value, or an appraisal by an independent appraiser. Agreements may apply or forbid discounts for minority interest or lack of marketability. Where there's no agreement, partners often hire one independent appraiser jointly, or each hire one and split the difference.

Does the departing partner stay liable for business debts?

They can. Personal guarantees on loans, leases and credit lines usually survive a buyout unless the lender or landlord releases them. Ask each creditor to release the departing partner or accept a new guarantor, and make the releases part of closing.
