Generally, no. But it depends on the machine

It is designed to hold pressure you know. :P
However, long term storage is different and depends on the specifics of the machine.

(I'm not an air compressor mechanic, dealer, or vendor. Just another diy'er and this is just my opinion)

I drain mine ~weekly, but leave it full, unplugged and the regulator backed off. Mine is stored in the basement. If storing outside (unconditioned space) I store it empty with the drain valve open.

It is good practice to drain them between uses, or at least at fairly regular intervals. The pressure isn't such an issue, they're made to take it. The reason is that you need to evacuate the moisture (in the air) from the tank. On even the driest days, I usually get a tablespoon of water from my compressor, which has a drain valve in the bottom of the tank. Draining at the regulator won't deal with all the moisture. Of course, the moisture will degrade the tank faster. Either way, you'll still get years of use, but a properly maintained tank will outlast a constantly wet tank every time.

Make sure you unhook any rubber air hoses if you let the compressor charged.
