To be honest I couldn't be bothered finding it as google searches keep returning chats on forums and so on. But feel free to confirm it with your local office, it's just a friendly warning for anybody who thinks they will be saving a month or two of tax. If you definitely need your car on the 3rd month, when you go to tax it you will be asked to pay for the previous 2 even if it's been off the road.

If I find something I'll post it up
Yep, this is my understandig of how it works now too, and I'm sure I've seen as much in official documentation. It's one of my biggest issues with the new system, as it does away with the option of taxing for say Apr-Jun, and then again Aug-Oct, with a month of storage inbetween
