On a similar note to Snootyjim's thread, but as it's different I thought I would start my own
I was employed until August last year on a proper contract then placed on retainer afterwards, I was charged tax at the regular rate for the 4 months in the tax year, but I did not earn over the threshold.
As my contract was switched I did not receive a P45 and I have yet to receive an end of year statement from the current company.
Is it possible using my tax code to contact HMRC and claim the tax back for the previous year? It's a fairly substantial amount so I'd rather get it back if possible for obvious reasons (and I made need the money if I gain a job and need to relocate)
