Business cards and where personal liability sits
The short answer
Most small-business cards are personally guaranteed. The company name printed on the card does not by itself shield the person who signed the application — the issuer can pursue the signer for the balance regardless of how the business is structured.1
What a personal guarantee means
A guarantee is a separate contractual promise, distinct from the business's own liability. It survives the business in most cases: if the company stops trading, the guarantee does not stop with it. That is the clause worth reading in full before signing, rather than the marketing summary on the application page.
| Arrangement | Who is liable | What to read |
|---|---|---|
| Sole proprietor | The individual, without limit | The whole agreement |
| LLC or corporation | The entity, plus any guarantor | The guarantee clause |
| Employee cardholder | The business, if properly authorised | Authorised-user terms |
| Account closed with a balance | Whoever guaranteed it | Acceleration and demand clauses |
Why the separation still matters
Even where a guarantee exists, holding a separate business account keeps the books clean and keeps business spending off a personal file. It also separates the reporting: business accounts are reported differently, and mixing them with personal spending makes both harder to read.
How a business account appears on a consumer report is not identical to a personal card, and whether it is reported at all depends on the issuer. Assumptions here are usually wrong.
Interest on carried balances
A business card does not shelter a balance from interest. In the Federal Reserve's most recent reading, the average APR on accounts that assessed interest was 22.36%, against 21.19% across all accounts.2 The rate applies to the balance whoever guaranteed it.
What to compare between offers
The reward category on the spending the business actually does, the fee against the benefit realised, and whether the issuer reports to business and consumer bureaus — because that last point affects a personal file for years.
Where the rules differ
Guarantee enforceability, entity formalities and consumer protections vary by state. The structure that shields an owner in one state is not automatically available in another.
