You can put as much as you like into a personal pension scheme, but there are limits on how much of your contributions will benefit from tax relief. For example, if you’re not earning at all, you can add a maximum of £3,600 including tax relief into a pension. If you are earning, you can put up to 100% of your relevant UK earnings into a pension to get tax relief, up to a maximum of £60,000. So, even if you earn enough to get more tax relief than this, you won’t receive it on contributions above this figure.
You also cannot reclaim more tax relief in a year than you were due to pay in tax, so you need to ensure your pension planning takes this into account. But you can do something called Carry Forward, which enables you to use any unused annual allowance from the previous three years, to maximise the benefits of any unused amounts from these years.
If you earn more than £200,000 a year, your annual allowance for pension contributions could reduce from £60,000 to as low as £10,000, so you must take this into account when making decisions about optimising your tax allowances towards the end of the tax year.
One important thing to remember is that if you are a 40% or 45% taxpayer, you may need to reclaim your additional pension contribution tax relief – anything above the basic rate of tax relief of 20% - through your tax return directly from HMRC. So, if this hasn’t been done, even in previous years, you should speak to your accountant for advice.
