Self employed people who have had maternity allowance - I've had mine come through assessed at £27 a week (is it even worth it?!) apparently due to the level of national insurance contributions. I pay these but obviously as I'm self employed I pay them in my tax return after the fact. Am I right that this therefore means I haven't paid 2018/19 class 2 yet as I'd usually pay this when the tax return is submitted end of this year and so I'd need to pay those contributions in advance now to get the full maternity allowance and then get my accountants to adjust my tax return so it shows I have already paid them?
