My state pension is paid every 4 weeks.
I have not had an answer to my question as yet, just that more info is needed. Therefore cannot comment on service.
Hi again.You are entitled to a personal allowance of £10,600 for 2015/16. From that, you deduct the state pension which is taxable but does not have tax deducted at source (£6,876 (£528.91 x 13)), to leave you with net allowances of £3724 which converts to a tax code of 372L. If that code is operated against your £629.54 pension, you will pay £63.84 per month in taxCall the tax office on the number here and ask them to review your tax codings and to make the necessary changes. They could even allocate £2,400 of your personal allowances against your £200 per month pension so that is paid to you gross and all your tax is then paid through one pension.The Personal Independence Payment you receive is tax free as you say. Confirmation of that is here.
As you retired in the 2014/15 tax year, you should ask the tax office to review your tax position for that year. They may issue a P800 tax calculation to you which you should check carefully.
Finally, I'd make a complaint about your previous treatment the next time you call the tax office if I were you.I hope this helps but let me know if you have any further questions.
