I was pushed hard on this last time I was interviewing. We danced around a bit, with them requesting and me declining, until they said they must have my previous salary because it is their policy. So I responded that it was my policy not to disclose my salary. They couldn't argue with that, and I got the offer I was looking for (which I ended up turning down anyway, but that isn't the point.) This is in the UK, but I don't see why it wouldn't apply anywhere.
