Personal credit follows you through your Social Security number or ITIN; business credit follows your company through its EIN and business records. New businesses usually rely on the owner’s personal credit at first, often through a personal guarantee. Separating finances early — a business bank account, an EIN and vendors that report — lets the business build its own profile over time.
Key takeaways
- Business credit reports come from business bureaus such as Dun & Bradstreet, Experian Business and Equifax Business.
- A personal guarantee means you are personally liable if the business does not pay.
- Some business cards report to personal bureaus only when the account is delinquent — ask the issuer.
- Keep business and personal spending separate; it simplifies taxes and protects your personal credit.

Five steps to start business credit
- Register the business and get an EIN.
- Open a business bank account and run all business income and expenses through it.
- Use a consistent business name, address and phone everywhere.
- Open accounts with vendors or a business card that report to business bureaus, and pay early or on time.
- Check your business credit files periodically and correct errors.
Protect your personal credit
Read every application for a personal guarantee, keep personal card utilization low even if you put startup costs on it, and avoid using personal cards for ongoing business spending. Our building credit guide covers the personal side.
Frequently asked questions
Can I get business credit with an ITIN?
Many businesses can obtain an EIN without an SSN, and some lenders accept an ITIN for the owner’s personal guarantee. Requirements vary by lender.
Does business debt show on my personal credit report?
Usually not, unless the account reports to consumer bureaus, you personally guaranteed it and default, or it is a sole proprietorship account in your name.
How long does it take to build business credit?
It depends on how many reporting accounts you have and your payment history; several months of on-time payments is a common starting point.
