Hi,
If your income is below the tax free threshold, your untaxed interest may be shown as present in your tax code, as you will still have unused tax free allowances, this amount will not be subject to tax.
Alternatively, it could be that your untaxed interest has been reported by your banks and building societies as being £1259, with the £259 after the savings allowance subject to tax. Please contact us so we can confirm why the untaxed interest is present.
