How to tax a SORNed car - Pondlife

My car has been SORNed for a couple of years and I'm now getting it back on the road again. I've insured it, but I'm having difficulties taxing it on the gov.uk website - it says the V5 reference number is not valid, I guess because of the SORN status.

Does anyone know the best way to tax my car? I want to do it online if possible.

Please ignore the previous post - I managed to tax the car using the V5 after all.
