This April the laws are changing so that they strongly incentivise companies who hire contractors to get them inside IR35. Prior to that, IR35 was mostly only observed by government agencies.
IR35 is being reformed in April 2020. It is not a new law, as I have pointed out to the previous poster. There are no radical changes to: a) either create a new law or b) morph it into creating another law, which is completely unrecognisable from it's current form. Your claim that it is currently ONLY being observed by 'government agencies' is not accurate. Furthermore, your reading of this reform being pushed as some form of incentive is incorrect.
In the interest of providing impartial advice to the author of this thread; it would be extremely wise to seek professional advice before embarking on this route, as the conditions of employment under IR35 are complex and subjective.
