Piggy bankMore than 3 million people paid double the amount of tax they owed on their savings in 2009/10, HM Revenue & Customs admitted this week.

Its figures indicate that only 718,000 people applied for a rebate of at least some of the 20% tax automatically deducted from standard savings accounts, despite some 3.5 million being liable to pay just 10%.



Pressure group Save our Savers, which is calling for the way savings are taxed to be changed, told the Daily Telegraph newspaper that many people are paying far more tax than they should on their savings.

"It is often pensioners, who have low incomes, but reasonable savings pots that are losing out," Save our Savers said.



"Better-off savers are given generous credit terms to pay the tax they owe on their savings, whilst pensioners and others on low incomes have to overpay immediately, then have to fill out various forms to reclaim their own money."

Why is this happening?
Anyone whose total income (including earnings or pension, plus any interest paid on savings and investments) is less than the annual personal allowance - £8,105, rising to £10,500 for those aged 65-74 and £10,660 for over 75s - can complete an R85 form to avoid 20% tax being deducted from their savings interest.

However, things get more complicated if your income is slightly above these levels as the 20% tax is always automatically deducted.

Pensioners and other savers on low incomes who qualify to pay tax at just 10% on the next £2,560 of savings interest earned must therefore claim the extra tax back themselves.

And thousands of them lose out because they do not understand how to make the claim.

So how can I avoid paying too much tax on my savings?
The best way to avoid tax on your savings is to maximise your ISA allowance. If you have cash in standard savings accounts, though, the first thing to check is whether you can have interest paid gross on your savings.

If not, and you can claim back the extra 10%, you must either complete a self-assessment form or an R40 form that you can find at your bank.

You will have to wait a while for the rebate to come through, but at least this way you will only pay the tax you owe - not more.
