It depends how much cash you have left in the company and the reason for closure. If you have good assets that you can't dividend out over a couple of years and don't want to work in the trade again then an MVL makes sense as can use "entrepreneurs relief" and pay 10% CGT on the first 1m. But to do an MVL incurs fees and you lose control of the company bank account from the moment the liquidation starts until its finished.

I think about 50k assets is/was where an MVL made sense but as others have said check with your accountant but if decent cash left after paying everyone then MVL is the best way to take advantage of the CGT tax break.
