If you are a non-taxpayer it is possible for you to have most income paid to you without tax being taken off.
Many of the problems of the 10% taxpayer, as for the non-taxpayer, are through having too much tax deducted from your income before you get it. However, unlike the non-taxpayer, the 10% taxpayer cannot ask for his income, such as bank interest, to be paid without tax taken off. This tax will have been deducted at 20%.
The Revenue may owe you a repayment and if so they will want to give it you back.
