Terence, based on information provided by you tax calculations for 2012-13 and 2013-14 are as follows:
Pension income - full year
Friendslife = £422
Prudential (116.68 x 12) = £1,400
State (699.32 x 12) = £8,392
Other income = £nil
Total (422+1400+8392) = £10,214
Personal allowance £10,500 same for both years
Total taxable = £NIL
Based on above calculations you should not be paying any tax.
I advise you to contact HMRC and ask them to review your tax code. They should communicate with your pension providers and amend your tax code as your income is less than your personal allowances.
If you need more information please let me know before you rate my service.
