There are arguments on both side of this coin, but I think it's better to be specific about what you earn when asked.
The likelihood of compensation verification by a hiring manager or through a recruiting agency is higher for sales-related positions, but is also increasingly popular in engineering and operations positions. Be as forthcoming as possible, but also give insights as to why you are seeking an increase beyond 10% of your current base. You may have a very good reason, and the hiring manager may agree. But they won’t go to the mat for you if they get false information.
