How business credit cards actually work, how they differ from personal cards, how to qualify, and what the IRS and CFPB say about them. Last verified April 2026.
This is a reference site, not a buyer's guide. We publish structural education on how business credit cards work as a product category, how the IRS treats the spending and the rewards, what the CFPB says about personal guarantees and disclosures, what Regulation B says about adverse-action notices, and what the Credit CARD Act of 2009 says (and largely does not say) about business cards. We do not publish live reward rates, sign-up bonuses, or rankings of specific cards because those terms change quarterly and we are not an affiliate aggregator with the operational capacity to keep them current.
The reader we serve is one step upstream of the affiliate listicle: the LLC owner, the new sole proprietor, the founder choosing their first business card, the bookkeeper who wants to understand the audit risk of mixed personal and business spend. For current product terms on any specific card, the CFPB publishes every issuer's card agreement quarterly at consumerfinance.gov/credit-cards/agreements. That is the authoritative source.
Read the methodology page for how we research, what primary sources we cite, and what we will and will not link to.
"Best" is a function of six variables, not a single answer. The right card for an owner depends on which axes the owner weighs and how. We name the six and link to the reference page on each.
Traditional revolving credit, charge card, corporate card, secured card. Each is structurally different in how it bills, who is liable, and how it reports.
Personal credit, time in business, entity type, revenue, and the issuer's stated underwriting criteria. The 5 Cs as the Federal Reserve describes them.
Flat-rate vs category-rewards vs tiered. Reward economics depend on interchange tier and category concentration in your spend mix.
Annual fee, APR, foreign transaction fee, late fee, employee-card fee. Business cards are not bound by the CARD Act fee caps.
Reporting to personal bureaus (delinquency-only or monthly balance) and to business bureaus (D&B, Experian Business, Equifax Business). Differs by issuer.
Personal guarantee vs corporate-only liability. The legal commitment that allows the issuer to pursue the owner personally on default.
Affiliate listicles lump traditional cards, charge cards, corporate cards, and secured cards into a single ranking. They are structurally different products with different liability, reporting, and billing models. Reading them as one category is like ranking sedans against pickup trucks.
Revolving credit line, monthly minimum payment, interest on carried balances, personal guarantee standard.
Pay-in-full each cycle, traditionally no preset spending limit, no carried balance, no interest charge.
Issued to the entity, underwritten on entity financials, centralised billing, often no personal guarantee.
Cash deposit becomes the credit line. Designed for thin-file or damaged-credit applicants.
Character (credit history), Capacity (cash flow), Capital (assets), Collateral, and Conditions (industry, entity, time in business). The framework the Federal Reserve and FDIC use to describe small-business credit underwriting.
Read /how-to-qualify →The legal commitment the owner signs that lets the issuer pursue the owner personally if the entity defaults. Almost universal on small-business credit cards. The CFPB has a public consumer-facing explainer.
Read /personal-guarantee →When an application is declined, Regulation B (12 CFR 1002.9) requires the issuer to provide specific reasons within 30 days. Most readers do not know they are entitled to this disclosure.
Read /how-to-qualify →What each identifier does on the application and when each is permitted.
How sole prop, LLC, S-Corp, C-Corp, partnership, and non-profit affect eligibility.
The two reporting patterns and what monthly reporting does to FICO.
The three business bureaus, PAYDEX, Intelliscore, and Business Credit Risk Score.
Section 162 ordinary-and-necessary, IRS Publication 535, the Section 163 interest deduction, and the recordkeeping obligation under Publication 583.
Rev. Rul. 76-96 treats ordinary rewards as a rebate, not income. Anikeev v. Commissioner is the narrow exception for manufactured-spending cases.
Why most CARD Act protections do not apply to business cards. The Truth in Lending Act business-purpose exclusion at 15 USC 1603, with citations to Regulation B and the Federal Arbitration Act.
The four revenue streams: interchange, interest, annual fees, penalty fees. Why business interchange is higher than consumer interchange and what that funds.
We map six common applicant profiles to the card category most likely to fit, and direct readers to the CFPB card agreement database for current product terms. We do not name specific cards.
The cards reference is the fourth volume in a small-business reference series. Each volume covers one foundational money-tool that a US business owner has to think about.
