Short answer
They can. Applying usually triggers a hard inquiry on your personal credit, and if you personally guarantee the card, its activity may show up in your personal file. Without a guarantee, activity generally will not. Issuers differ, so ask how yours reports before you apply.
Two moments when your personal credit is involved
The first is the application. Most issuers pull your personal credit when you apply, which creates a hard inquiry. Chase notes that the effect is usually short-lived and lowers a score by only a few points.
The second is after approval, and this one depends on the personal guarantee. If you guarantee the card, its activity can reach your personal file. If you do not, Chase says the activity will not affect your personal credit. Some issuers report only to business bureaus, so it is worth checking.
What changes with a personal guarantee
| Situation | Personal credit | Business credit |
|---|---|---|
| You apply | Hard inquiry, usually small and short-lived | Nothing yet |
| Card with a guarantee, paid on time | May appear in your file; balances can count toward your utilization | Can build your business file if the issuer reports to business bureaus |
| Card with a guarantee, missed payments | Late payments can hurt your personal score | Can hurt your business file |
| Card without a guarantee | Generally no effect after the application | Reported to business bureaus only, depending on the issuer |
Capital One puts it this way: with a guarantee, missed payments may be reported to both business and personal bureaus, and a default can hurt both scores. Read our guide on what a personal guarantee means for the detail.
Utilization is the quiet one
If a guaranteed card reports to your personal file, a high balance can raise your personal utilization even when the spending is entirely for the business. Chase recommends keeping utilization below 30 percent on all your cards, business cards included. For sellers who buy inventory on a card, that takes planning.
How to protect yourself
- Ask the issuer before you apply: "Do you report this account to personal credit bureaus, or only business bureaus?"
- Apply for one card at a time instead of several in the same week.
- Pay on time, every time, and pay down balances before the statement date if you can.
- Keep the business and personal sides separate. Mixing them creates its own problems.
The upside
A card that reports to business bureaus builds your business file, which is the whole reason to use one for credit building. Our page on which business cards report to business bureaus goes through how reporting works.
