We send you a certificate of interest annually, the letter is issued shortly after the closure of the tax year. The letter confirms the interest you’ve earned within the previous tax year. It is your responsibility to calculate any tax owed above your Personal Savings Allowance.

You can also request a copy of your certificate of interest for the previous tax year at any time - just call us on 0203 370 0970, select option 2, and we’ll sort it out 8am-8pm Monday to Friday (except bank holidays).

The letter confirms the interest you’ve earned from your Tandem Account within the previous tax year. We don’t take any tax off the interest we pay you.

Your Personal Savings Allowance is the amount of interest you can receive tax free and depends on your taxable income. You may have to pay additional tax. You can find more information by searching Personal Savings Allowance on www.gov.uk.
