Maximise your Income - Tax
Confirm with your local tax office to make sure that you have the right tax code. If you are married, responsible for bringing up children, elderly, widowed or registered blind, you can get a higher tax allowance.
If you are married and either you or your spouse earn less than the married person's tax allowance, it may be worth transferring the whole of the allowance to the other partner.
Confirm to see if you are entitled to tax relief on any maintenance you have to make.
You may be able to claim tax relief on work related expenses, again check with your tax office.
Extra tax allowances can be back-dated for up to six years. The Inland Revenue will also pay you interest.
