If you're a UK resident under the age of 75, the general rule is you can contribute to all of your pensions as much as you earn and you will receive tax relief on your contributions.
For example: If you earn £30,000, you should be able to contribute £30,000 gross to your pension. The payment you make will be £24,000, to which the taxman will add basic-rate (20%) tax relief of £6,000.
Higher and top-rate taxpayers can claim back the additional tax they have paid through their tax return.
A pension annual allowance of £40,000 and a lifetime allowance of £1 million apply and if you have income over £150,000 your annual allowance is tapered down from £40,000. Please read our taper relief guide for more information.
Please remember that tax rules can change in the future and there are other factors that affect how much you can pay into your pension, which you may need to consider.
