I am completing my self assessment online and have earned over the threshold to pay Class 2 but it is saying I own '0.00' in the NI2 section and saying 'NI2 amount not available' in the full calculation section.
I can't select to pay voluntarily instead as it then comes back with an error saying I have earned over the amount to do this.
I paid NI2 via self assessment last year so am all set up to do so.
Can anyone shed any light on what's going on. Is this an error in the HMRC's system?
