Do US corporate cards require a personal guarantee from the founder?

Usually, no—if it’s truly a corporate card. Many corporate-card programs make the company responsible for the balance and don’t require the founder’s personal guarantee. The issuer may instead assess the company’s cash, revenue, or other financials. (nerdwallet.com)

But “business card” and “corporate card” aren’t interchangeable: many small-business cards do require the owner to personally guarantee the debt. (chase.com)

Before applying, check the agreement for “personal guarantee,” “individual liability,” or “joint and several liability.” A personal credit check by itself isn’t necessarily a guarantee.

Short answer: not always. Traditional business credit cards usually require one, but many corporate cards, especially fintech charge cards, don't.

Traditional business cards. These typically ask the owner to guarantee the balance. Dash.fi's comparison puts it bluntly: Business Credit Card: Almost always required. Issuers lean on the founder's personal credit because a young company often has little of its own. For early-stage startups, the founder is typically the individual that personally guarantees the business credit card.

Corporate cards. These are usually underwritten on the company's finances. Dash.fi notes that approval is usually based on the business's financials, including cash flow and operating history. Several issuers, including Brex, Ramp, and Rho, advertise no personal guarantee and no personal credit check. Most of the "no PG" lists I found come from these issuers' own marketing, so treat their claims as their own and confirm the terms in the application.

Catches to check:

• Eligibility is stricter. Some business credit cards do not require personal guarantees – but credit card issuers typically only approve these for companies that meet fairly high revenue and cash-on-hand requirements. For example, one review says Brex can be approved without a guarantee if your company has at least $50k (startups) to $100k+ (angel-funded companies) in the bank.
• "No PG" doesn't always mean no guarantee. One guide warns that some credit card issuers may require a personal guarantee from the business owner or a designated individual within the company, even for cards marketed as "no personal guarantee." Read the cardholder agreement itself.
• Charge cards need full payment. Many of these cards are charge cards. One review notes you must pay all balances in full each month, and you cannot make balance transfers.
• Loans are a separate question. A guarantee on a bank loan or SBA loan is a different obligation. The US Small Business Administration mandates an unlimited personal guarantee from any owner with at least a 20% stake in the company.

If you're a funded startup with a healthy bank balance, a no-PG corporate card is often realistic. If you're pre-revenue or lightly capitalized, expect a guarantee or a lower limit. Ask the issuer directly whether any personal guarantee applies before you apply.

Whether a US corporate or business card requires a personal guarantee depends on the type of card and the financial maturity of your company.

The Short Answer

• Most small business credit cards require a personal guarantee. Even if your business is incorporated (e.g., an LLC or Corp), most card issuers require the founder or a principal owner to sign a personal guarantee. This means that if the business defaults, you are personally responsible for the debt.
• True "corporate cards" often do not require a personal guarantee. These products are typically designed for larger or more established companies. Instead of relying on the founder's personal credit, these issuers underwrite based on business financials, such as revenue, cash balances, and business credit history.

Key Distinctions to Understand

1. Business Credit Cards vs. Corporate Cards

• Business Credit Cards: These are widely available and commonly used by startups and small businesses. Because these companies often lack an extensive commercial credit history, issuers use the personal guarantee as a risk management tool. When you sign the application, you are essentially "co-signing" for the business, which can put your personal credit and assets at risk if the business fails.
• Corporate Cards: These are intended for more mature companies with significant revenue (often seven figures or higher) and an established business credit file. These programs provide corporate liability, meaning the company is responsible for the charges rather than the individual owner.

2. Why Issuers Require a Personal Guarantee

Lenders view a personal guarantee as "skin in the game". It ensures that the business owner is motivated to keep the account in good standing. Without this, the lender’s only recourse if the business fails is the business’s own assets, which may be nonexistent in an early-stage startup or small company.

3. Can You Avoid a Personal Guarantee?

It is possible to avoid a personal guarantee, but it usually requires meeting strict financial criteria:

• Established Business Credit: Your company must typically demonstrate several years of operation and strong, verifiable revenue.
• Cash-Flow Underwriting: Some modern corporate card providers (such as Brex or other spend-management platforms) offer products that don't require a personal guarantee, provided the company meets specific cash-balance or funding thresholds.
• Secured Cards: In some cases, you may be able to secure a business card by providing a cash deposit, which acts as collateral and may reduce or eliminate the need for a personal guarantee.

Important Advice for Founders

• Read the Fine Print: Even if a card is marketed for business use, the application may contain "Legal Responsibility" or "Liability" clauses that create personal obligations. Always check the terms before signing.
• Avoid Commingling: Never use a business card for personal expenses. This can lead to "piercing the corporate veil," where a court may rule that your business entity does not actually protect your personal assets, regardless of what the card agreement says.
• Understand the Liability: If you are a co-founder, be aware that if you are the only one who signs the guarantee, you could be the only one held liable for the company's debt.

No—not universally. Many US corporate-card programs don’t require the founder to personally guarantee the balance. They assess the company’s finances instead; for example, Ramp says it evaluates business cash, cash flow, and revenue and does not require a founder personal guarantee ¹².

But “corporate card” doesn’t automatically mean “no personal guarantee.” Requirements and liability arrangements vary by issuer and program. Some business cards commonly require a personal guarantee, and corporate programs can also have different liability terms. Check the application and card agreement for language such as personal guarantee, individual liability, or joint and several liability before signing ⁶⁷¹³.
