Personal Guarantees on Business Loans: What You're Signing

By the GoHarvest editorial team · Updated · 2 min read · Building business credit

Short answer

A personal guarantee is your promise to repay the business's debt yourself if the business doesn't. It puts your personal assets behind the loan despite the LLC or corporation. Most lenders require one from owners of young or small companies, and SBA rules generally require one from every owner of 20% or more.

Key points

  • An LLC or corporation protects you from many business debts, but not from debts you personally guarantee.
  • Unlimited guarantees cover the whole debt plus costs; limited guarantees cap your exposure by amount, percentage or time.
  • Under 13 CFR 120.160, holders of at least 20% of an SBA borrower generally must guarantee the loan.
  • You can sometimes negotiate the cap, release conditions or collateral, especially with a strong track record.

The single most consequential line in many small-business loan files isn't the interest rate. It's the guarantee. An owner who formed an LLC to keep business debts away from the family home can undo that protection with one signature.

What a guarantee does

Normally, a limited liability company or corporation owes its own debts. If it fails, creditors can take company assets but generally not the owners' personal ones. A personal guarantee changes that for a specific debt: you promise the lender that if the company doesn't pay, you will. The lender can then pursue your savings, your home equity (subject to state exemptions) and other personal assets.

Common types

Type What you owe if the business defaults
Unlimited The full outstanding debt plus interest, fees and collection costs
Limited by amount Up to a fixed dollar cap
Limited by percentage A share of the debt, often your ownership percentage
Limited by time or condition Expires after a period or once the business meets targets
Joint and several With several guarantors, the lender can collect the full amount from any one of them

Read the joint and several language carefully. If you own 25% and sign a joint and several unlimited guarantee, you can be on the hook for 100%.

When guarantees are required

Very often. Banks, SBA lenders, online lenders, equipment lessors and commercial landlords commonly ask owners of small businesses to guarantee, because a young company's assets and history aren't enough security on their own.

SBA's rule is explicit: under 13 CFR 120.160, holders of at least a 20% ownership interest generally must guarantee the loan, and SBA or the lender may require guarantees from others regardless of their percentage. SBA has its own forms for unlimited and limited guarantees (Forms 148 and 148L).

Merchant cash advance contracts often include a "performance guarantee" instead, which typically makes the owner liable if the business breaks certain promises, such as switching bank accounts or hiding sales. The wording varies widely and is worth reading line by line.

What you can negotiate

Lenders have less flexibility on small or young credits, but these points are often worth raising:

  • A cap. A dollar or percentage limit instead of unlimited.
  • A burn-off. The guarantee shrinks or ends after a period of on-time payments, or once the loan balance or the business's debt coverage hits a target.
  • Collateral swap. More business collateral in exchange for a lower guarantee.
  • Several, not joint and several, among multiple owners.
  • Release on sale. A written process for releasing you if you sell your stake.

Ask early, in writing, and keep the lender's answers. If the debt is large, have a lawyer read the guarantee before you sign.

Reducing how much rides on you

Guarantees are a fact of small-business life, but the exposure can be managed: borrow amounts the business can carry, keep business and personal money strictly separate, maintain adequate insurance, and avoid stacking several guaranteed debts at once.

Questions people ask

Does a personal guarantee show on my personal credit report?

The guarantee itself usually doesn't appear as an account. But the lender may check your personal credit when you sign, and if the business defaults and the lender comes after you, collections or judgments can show up on your personal file.

If I sell my share of the company, does my guarantee end?

Not automatically. Guarantees usually stay in force until the debt is repaid or the lender releases you in writing. Getting a release is a standard item to negotiate in any sale; see our pre-exit credit guide.

Can my spouse be required to sign?

Rules limit when a lender can require a spouse's signature. Regulation B under the Equal Credit Opportunity Act restricts creditors from requiring a spouse to sign if the applicant qualifies on their own, with exceptions such as where jointly owned property secures the loan. If you're asked, ask why, and get advice.
