I've been contracting for many years now. It's a good writeup, but as the top comment mentions - these are the basics. There is a lot of nuance. I'm exclusively Outside-IR35, and since this was rolled out to the private sector it dried up a lot of work as companies were spooked for no reason about this. There is still work out there but the market is not as good as it was a year ago. The rates mentioned in this article are 'bad market rates'. Good market rates are higher. I've seen some mention Inside-IR35 - there is a catch there. If you've done outside work, and then go inside, your tax gets bundled up and you can potentially end up paying top rate from the get-go, or finding your self with a higher tax burden than you expected. Talk to your accountant about that if you're planning to take on Inside gigs or a mix of both. I'd avoid umbrellas at all costs.

Mixing inside and outside contracts can be quite tax efficient but requires being diligent. For example, an inside IR35 contract that partially spans two tax years can be used to take the "reasonably cheap" first 50k of salary of each year, with any extra put in a SIPP. Then, outside contracts in the same tax years are used just to accumulate money in a limited company with a view to withdraw funds via BADR at some point, and potentially used to top up the SIPP as well.

Interesting approach. My personal case is more complicated but this is still interesting. As an aside, my accountant raises a point that mixing might raise some flags with HMRC regarding status.

Working with a different statuses for the same client should definitely be avoided as HMRC will be sceptical that the working practices are actually different between contracts. Working differnent statuses for different clients shouldn't be an issue IMHO
