Only 3 month's IT Contract through Limited Comapny

[Bluebird]

No - IR35 is designed to stop disguised employees avoiding paying PAYE and NI. Whether this is a permie going contract or the other way round is neither here nor there - in fact I would think this is more likely to be IR35 caught, since there is not much argument to be had for proving that this isn't just a three month trial period.

IR35 was introduced to stop the permie-contract flow.

It's not quite the same the other way around, somebody who is outside of IR35 in contract & working practices CAN become an employee, and thus recieve the benefits of employment, but pay the price by paying PAYE.

Just because your employment status changes from Contract to Permanent Employment DOESN'T put you inside IR35 for the contract element of you assignment.
