How do I work out my tax?

For most pensioners with simple tax affairs the way the tax calculation works is as set out below. Remember that the tax year runs from 6 April one year to 5 April the next.

£
Income (most income is taxable although some may be tax free) xxxx
Take off the tax free amounts called personal allowances. Everyone get one of these but it varies with age and level of income (xxxx)
Take off the allowance for those who are registered blind (xxxx)
You are left with the amount of your taxable income xxxx
The next stage is to calculate your tax liability xxxx
Then take off the amounts you get due to special allowances (xxxx)
Then take off any tax already deducted from the income you receive before you get it (xxxx)
Tax now due or (repayable)

xxxx or

£ (xxxx)

Once you feel comfortable with the various stages in the tax calculation process you may want to check your understanding by having a look at 2 simple examples, which follow.

Amy - occupational pensions - state pension - savings income

Amy is aged 80 and single. She is registered blind. For 2012/13 she has the following income - we look at two different amounts of income so you can see how the starting rate for savings of 10% can affect your tax bill:
Income before tax Tax taken off
£ £
Occupational pension from BT 7,230 1,000
Occupational pension from local council 4,330 550
State retirement pension 5,730

If Amy's pension income is £13,890 instead of £17,290 for 2012/13 - she will be able to use part of her starting rate for savings tax band so some of her interest on Income Bonds will be taxed at 10% rather than 20%.

  1. The rate of Amy's income depends on the type of income she has.
  2. Amy's income is less than £25,400 so she gets her full personal allowance.
  3. Amy is registered blind and so she gets an extra allowance.
  4. This is the income on which Amy pays her highest rate of tax so we take her allowances from her pensions first so that she pays as little tax as possible.
  5. We use savings income before any tax is taken off when working out Amy's tax. In the second example Amy still has part of her starting rate for savers unused so part of her interest is taxed at 10%. If you would like more information on how the starting rate for savers works you can find that here.
  6. Dividends are taxed at 10% unless you are a 40% taxpayer. Amy pays tax at 10% on the amount of her dividends.
  7. Amy has no special allowances.
  8. This is the tax taken off Amy's income before she receives it so we need to take this off her tax bill.

  1. This is the income on which Will pays his highest rate of tax so we take his allowances from pensions first so that he pays as little tax as possible.
  2. Will gets married couple's allowance of £7,705 and so he can get £7,705 divided by 10 = £770.50 taken off his tax bill. Will's will get the full allowance as his income is not high enough to trigger any restriction.
