Hi, can you please advise how I can calculate my payroll taxes in Bullet

The payroll software will do it for you automatically. The the P35 and P35l are ready they'll appear on your todo list.
When you pay yourself you'll see all your taxes in the review screen for that month.
Have you installed the payroll app?

Sure, make sure you use the P2C file from ROS to set yourself up on Payroll. If you do it manually it will result in terrible mistakes.
You can get the P2C file from ROS. Simply download it and import it into Bullet and we'll set everything up automatically.
