At Nutmeg you can invest inside or outside of an ISA.
While you can set up or transfer an ISA to Nutmeg, there is no obligation to invest within an ISA wrapper.
If you don't select to invest in an ISA your investments with Nutmeg will remain in a standard taxable account.
If you have an ISA with Nutmeg you can still invest beyond the ISA limit for the year (or the limit that you set). We will first subscribe contributions to your ISA until you reach your ISA limit. Contributions beyond that will be held in a standard taxable account.
