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

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...

im 17 and have just started part time work at pc world however ive now had two pay slips and had tax deducted from both when i shouldnt have done my employer has sent off a P46 form. my current tax code is Ot W1 , what should i do?

i have just recived my first pay slip and it has taxed me 57£? it says my national insurence number code is : A and my tax code is BR i have been told this is a temp code? and i will be refunded? i only got paid 225? why is it so much? and what...

My tax code has just changed and the tax man is taking 50% of my money every month,i have tried all the help numbers on the tax site but nobody answers,has anybody been in the same situation and is there a secret number to call the taxman,I am on low...

what does this tax code 547T mean for me, is it a normal tax code or is it a high tax code

Im not sure if i have the correct tax code at the moment (&&I dont really understand the codes and I have looked online and just feel really lost! Could someone explain it to me - simply =p) My tax was really high this month.. 1/4 of my wages...

My state tax return was rejected and I need to get "help" but I cant find the error code to do that.

since ive started work which was a year and half ago, ive been automatically on BR. after tax i get around £650 and get taxed around £200 how do i change my taxcode so its not on emergency tax?

I think im paying too much tax, i heard there is a website that goes through all your circumstances and allows you to make sure you are on the correct Tax Code. Is this true and if so what is it?
