National insurance on second, self employed job?

r.woolsey

Apologies if this isn't the correct board to post this in, however I am just about to set up a side business in addition to my regular PAYE job.

I am trying to work out how much to set aside each month from this second, self employed role for when I need to file my tax return and I am getting a bit confused in regards to National insurance contributions.

On the GOV website it mentions a category J (2%) - Employees who can defer National Insurance because they’re already paying it in another job

As I already have another full time job which is the bulk of my earnings each year, does this mean I fall under category J and only need to set aside 2% each month for NI contributions for the second job?

I have seen a few articles online which contradict this so wanted to check before getting too excited

Unless you already earn more than the NIC upper earnings limit on your main job (i.e. over £50k or so), no, you'll be liable to class 2 and class 4 NIC on your s/e income if you breach the relevant lower earnings limits for those (separate limits for each).

I am both employed and self-employed and Pennywise is spot on unfortunately
