How can I find out what tax code I'm on?

Help need information about Tax code BR and p45?

• I started a new job in august and after months of requesting my p45 from my previous employer have still not received it. I have tried contacting my local tax office but can never get through and cant find the relevent information i am looking for online. so if anyone could answer my questions i would be grateful. Can i give my present employer a alternative piece of documentation like p46 after i have received my first paycheck? My current tax code is BR is that a emergency tax code and will i be able to claim tax back? It says online BR is used when you changed jobs or have a second job so im unsure if i will get the tax back as its been so long but i have only received one wage. If anyone could help i would be grateful.

• Answer:

  If this is your only job right now - get a P46 from your employer - tick Box B - fill in personal bits and hand it back. That will put you on 647L X (week/month 1) and decrease the tax bite. The process then is automatic - HMRC computer notes and makes a workitem - at the worst you go on a cumulative code in April and HMRC will get back to you with a rebate later.
