Hi Nick,
Thank you for your query
As an invigilator your wife will be a part of the Self-Employment Exception group where Class 2 is voluntary and she does not pay Class 2 through Self-Assessment. How it works when you are an invigilator you are sent yearly Class 2 voluntary bills in the post. The bills are usually issued September/October time during the year.
If your wife has not yet received her Class 2 bill for 2023/24. Please contact the helpline.
If she also wishes to pay the prior years to 2023/24 at Class 2. She would need to contact the helpline and we would provided bank details and a reference number to make the payment to.
