When making Class 3 voluntary contributions to fill missing years in your NI record, do you pay the full annual sum in one payment or do you / can you pay monthly? I was under the impression that I would have to pay monthly by direct debit, which would limit the number of years I could realistically commit to paying before the April 2025 cut-off. But if you're required to pay for each year in one lump sum then I could wait until nearer the end of the year and see how many years I can afford to pay in one go. I would appreciate clarification.
