Well, I setup a consulting company in my own name a couple of years ago and I've been keeping the money in the company for now, while I also have a half time job. I'd like to start paying myself out of the company this year, but I won't be giving up my other job
The first thing is that you need to register yourself as an employee for your own limited company. You can ring up revenue to do this. After that, they will register you as an employee of your company, and give you tax details for that employment. You can download these details from ROS (it's a P2C file) and import it into Bullet. After that, you can start paying yourself, and Bullet will calculate the tax etc, and the P30 returns.
