Is there a federal law requiring your annual income on credit application?

No. I recently refused to fill out the line that states annual income on a Nordstrom credit application. (I felt my 802 FICO spoke for itself). I was told by the credit department 3 times by 3 different people there was a Federal Law requiring this information, which they refer to as the " Consumer Credit Protection Act" of February 2010. I researched the Act and there is no requirement to state annual income on a credit application. In fact, that Act is to protect the consumer from credit card companies, not the other way around. After speaking with a supervisor, and waiting on hold for him to research, he admitted there was no law, just a rule from "somewhere" that requires them to "gather information on the applicants ability to pay". Pulling up the applicants credit history is sufficient information to issue credit.
