WTC/means tested ?

on the gov.co.uk calculator, it gives the impression that this benefit is not means tested. OK it asks a few Qs, but not "how much you got", merely "what is your income"

When you get the form, it DOES ask what gross interest from banks/bldg socys, you get. Ignores ISA - why if gross interested is requested.

So they DO take gross interest into account when assessing you gross income - true ?

thanks
