I want to pay tax on bank interest without it appearing in my tax code. How can I arrange to do that?

My interest this year will just exceed £1000 but next year it will be close to or probably above £10000. I don’t want this included in my tax code. So I need to pay directly. Can I voluntarily fill in a self assessment return for this year and in all subsequent years ( I realise if interest is over 10k then I must file) and arrange to be billed for my tax owed directly? When would I need to pay, presumably shortly after filing a return for the previous year? Do I need to provide an accurate estimate of the amount owed in the previous years tax return ( I’m concerned there is some penalty if I pay the following year for interest earned in the previous tax year).
