I have a ING high interest account, and since my new job I have a lot more money saved in there.
Every month I get interest, and then every time the interest comes in, they take away 'Witholding tax' .. I have figured out this is because they don't know my Tax File Number, if I call them and provide them with they adjust it?
Or refund if they have taken away too much? Worried I may be losing money
