What is best an ISA or a SIPP?

With longer life expectancies many investors are concerned about their retirement income. Some are now looking to boost their pension funds, either by topping up company schemes, or by using alternative vehicles.

One such vehicle is the Individual Savings Account (ISA) which could help to ensure your retirement income is as healthy as possible. ISAs and pension plans are both seen as tax efficient investment vehicles. However, there are big differences between the two. For example, when you put money into your pension plan, the contribution qualifies for a tax rebate at your marginal rate which, for a higher rate taxpayer, can add a significant amount to their investment. However, in exchange for this benefit, you must keep your money invested until at least age 50 (rising to 55 in 2010), and on retirement, the income you receive back is taxable, and counts towards your personal allowances.

With an ISA, the money you invest comes from taxed income and no rebate will be given. However, ISAs have no minimum term - so you can withdraw the proceeds or an income at any time you like. In addition, any income you do withdraw will be tax free and will not count towards any personal allowances. Which approach is best for you depends entirely on your personal situation. Perhaps the healthiest way to approach it is to combine the two.
