    Mark Grimm, a speaker and communications coach, said, "Telling the prospective employer what you make is a mistake for so many reasons. It gives them leverage when you get to salary. It may lead to them thinking less about your skills in circumstances where you were underpaid. It can create an artificial starting point that otherwise would have been higher. Just say, 'That's proprietary information,' if asked."

    Some employers insist that you provide a ballpark figure for your desired salary. This gives you the opportunity to avoid a disappointing offer that you would be inclined to refuse by never disclosing your current salary. Give them the salary range you're expecting, not the salary you're making at your current job.
