Important information about taxation

Up to 5th April 2016 and subject to certain exceptions credit interest will be paid net after deduction of tax at the basic rate under current legislation. If you are a higher rate tax payer, you may have additional tax to pay.

Credit interest will be paid without deduction of tax to UK residents who are non-tax payers and who provide a valid Form R85.

Credit interest will be paid without the deduction of tax to individuals who maintain a balance of at least £10,000 and who are not resident in the UK and who have provided us with a completed non-resident declaration Form R105.

Credit interest will be paid without deduction of tax on accounts held by companies, certain trusts, pension funds, clubs, societies and associations, provided the appropriate documentation is in place.

From the 6th April 2016 credit interest on all accounts will be paid gross (under new legislation tax will not be deducted when credit interest is paid). If your credit interest is more than your Personal Savings Allowance you may still have tax to pay. Please see for information on the Personal Savings Allowance or speak to a tax advisor.
