  • RE: Two National Insurance Numbers

    I also have this issue. Is there a way to resolve this without calling the Taxes helpline number as you have to hold for a long time before getting through? Please note that I have called the helpline and written several times to highlight this issue over the last 1.5 years. And keep getting penalty notices for not having submitted my tax return. When in fact i have submitted my tax return using my usual NI number.
