When I complete the 'Check if you need to send a Self Assessment tax return' on line it tells me I don't need to. However I've calculated I need to pay tax on savings interest; how do I do this without completing a Self Assessment?

I have checked on the HMRC site using the tool and it tells me I don't need to complete a Self Assessment Tax Return. According to my calculation I am liable for about £200 in tax for interest earned from building society accounts. How do I pay my dues without completing a Self Assessment Tax Return?
