Transfer and tax query

Hi, I'd like to thank B&W as thanks to their invaluable guides I was recently transferred from IB to the WRAG(CB) group without the dreaded medical.

I've asked for a reconsideration as I believe I qualify for the support group. As with lots of you what was written on the TL54 form significantly contradicted what I had put on my ESA50 although it did say that a return to work was unlikely.

My query is that as I have a small pension because I had to leave work on health grounds I've now been sent a form to say it will be taxed. I'd been on Incapacity benefit for approx 16yrs and so never paid tax on it previously. I understood from info here that there should be transitional protection for people in this position and so I shouldn't be paying tax. Does anyone know if this it right and if so would I take it up with the DWP or tax office?

Thank you everyone who contributes to the main site and the forum, you offer such invaluable help and support and good wishes to everyone struggling in any way.

By the way, my esa50 went in on may 31st, they didn't ring me- just sent a letter dated 25th july to say I qualified for the WRAG group. I had a letter for an interview with the 'Adviser' but had to postpone it due to medical tests to it's now in november. (S yorks area)
