What is the difference between business credit and personal credit?

Business credit is a separate profile tied to your business EIN and legal entity, tracked by commercial bureaus like D&B, Experian Business, and Equifax Business. Personal credit is tied to your SSN and tracked by the consumer bureaus. Lenders may check one, the other, or both.

When you apply for business financing, a lender may check your personal credit report, your business credit profile, or both — depending on the loan type, loan size, and how long your business has been operating. Understanding how these two credit systems work helps you know what to build and what to protect.

How personal credit works

Your personal credit history is tied to your Social Security Number (SSN) and tracked by the three consumer credit bureaus: Equifax, Experian, and TransUnion. Your FICO score (most commonly FICO 8) summarizes this history on a 300–850 scale. Lenders use it to evaluate you as an individual borrower. The CFPB explains what goes into a credit score — payment history and amounts owed carry the most weight.

How business credit works

Business credit is tied to your business EIN (Employer Identification Number) and legal entity. It's tracked by commercial bureaus — primarily Dun & Bradstreet (D&B), Experian Business, and Equifax Business. D&B uses a Paydex score (0–100); Experian Business uses an Intelliscore (1–100). Both measure how promptly your business pays its suppliers and creditors. Unlike consumer credit, business credit reports are generally accessible to anyone who pays for a report on your company.

How lenders use each for small business loans

Early-stage businesses (under 2 years): Most lenders rely primarily on the owner's personal credit because there is little to no business credit history.
Established businesses with a credit file: Lenders may review business credit scores alongside personal credit and business financials.
SBA loans: Require a personal credit check on all guarantors. The SBA's lending criteria also assess business financials and ability to repay.
Trade credit (net-30 vendor accounts): Reports to business bureaus only, not personal bureaus — a primary way to build a business credit file.

Key differences at a glance

ID anchor: Personal = SSN; Business = EIN + legal entity name.
Score ranges: Personal FICO: 300–850. D&B Paydex: 0–100. Experian Intelliscore: 1–100.
Report access: Personal credit reports are protected by the FCRA and available free via AnnualCreditReport.com. Business credit reports can be purchased by anyone.
Liability: Personal credit activity can affect your personal finances directly. Business credit defaults may still trigger personal liability if you signed a personal guarantee.

Key takeaways

Business credit is tied to your EIN; personal credit is tied to your SSN — they are separate files.
Most early-stage businesses qualify on personal credit until a business credit file is established.
Building business credit requires accounts that report to commercial bureaus (D&B, Experian Business, Equifax Business).
SBA and many term loans require a personal credit check on all guarantors regardless of business credit strength.
A strong business credit file can reduce the weight lenders place on your personal score over time.
