All three credit bureaus collect mostly the same basic information about consumers. This includes personal data, such as name, address, Social Security number, and date of birth. It also includes credit history, including debts, payment history, and credit application activity. It is common practice for the credit bureaus to collect information on federal and private student loans and from housing lenders.

If you are delinquent in making student loan payments, Sallie Mae can report that to a credit bureau—typically after you are 45 days late. Federal loans provide more leeway, allowing 90 days to pass before the servicer will file a report of a delinquency.

The Internal Revenue Service (IRS) doesn’t report income tax payments or overdue taxes to the bureaus. However, if a taxpayer does not pay their tax debt in a reasonable amount of time, or if they owe a lot of back taxes, then the IRS might file a federal tax lien (a legal claim against a taxpayer’s property) with the local county clerk’s office. A tax lien filing is considered public information, and the bureaus can find it through third-party research.

Note that not all lenders report credit activity to every credit bureau, so one bureau’s credit report can differ from another credit bureau’s. Even when lenders report to all three bureaus, their information may appear on credit reports at different times simply because the bureaus compile data at different times of the month.
