I would enter $1, as mentioned elsewhere. "I noticed you entered $1 here. Can you please correct with your actual salary?" Answers: "No" "I'm sorry, but I do not share previous salary information" "As a matter of principle, I won't be sharing previous salary information" "Yes I'm aware that it is required, and I would love to work for BigCo, but I won't be sharing my previous salary information" "I understand you need to enter salary information, but I do not share that information with any prospective employer. I sincerely hope we can move forward." Notice that the reasoning for each response is "because I said so" and is not open to prying HR tactics. They will try hard to make you second guess yourself, they may revoke the offer. Stick to your guns, "No salary info. I'd love to work there. Let's move on."
