If it's on the road (physically) it must be taxed (plus insured plus MOT). If you don't have a licence for it you won't be able to insure it for road use, so this option is out anyway.

If you have it physically off the road and aren't going to use it until May, why not send the tax disc off for a refund and declare it SORN? You can either get the form from a Post Office or download it from the DVLA website and stick the tax disc on it (remember to cross the "declare SORN" box) add a stamp and post it.

You get some cash back and just tax it again when you want to use it. Simple.
