Wrong - that's just a myth. Failure to display your tax disc is a separate offence to not actually having paid for the tax. Even if you have a disc it is an offence not to have it in your window.

I have not received the tax disc. Can I use the vehicle without the tax disc displayed?
When you apply for a tax disc online or by using our phone service you are able to legally continue to drive your vehicle for up to 5 days after the tax disc has expired while you wait for the new tax disc to arrive. This will only apply when you have applied for a new tax disc before the current one expires. You should continue to display the expired disc on your vehicle, until the new one arrives.
So dont know really with where i stand taxing whilst the car was sorned? Thats the point i was making i tried to apply before the 1st so i could have my disc in time but they would not give me the option when to start the licence from.
Not if you always wait until its run out first then like I do!
