Okay last tax year - part time employed part time self employed but didn't earn enough to go over the threshold to need to pay class 2 contributions (pay class 1 via PAYE).
This Tax year- will definitely earn over the threshold but until 1st Sept still employed and paying class 1 NI.
What is unclear to me is whether I start paying my class 2 NI now for this tax year (alongside my class 1's) or wait until Sept or wait until I have earned over the threshold (maybe Oct).
It seems like I will be doubling up on NI contributions if I pay both but I guess it must be somehow proportional to total income so I won't be paying more?
