Tulips

Just a question regarding my tulips: Should I wait till the foliage has completely withered to cut them back? Or can I cut them back now that the leaves have started to fade and yellow? They are a perennial variety, so I don't want to stunt their return next year. I would like to clear their dying leaves though, so I can put in some annuals. The flower bed is looking a tad sickly at the moment. Thanks!
