Umbrella or PLC (or any other means!) to maximise this payslip

Hello,

I contract through an umbrella company. I was hoping someone could look through the typical pay slip below and tell me if it's worth forming a company and paying an accountant and whatever else is involved.

I've got to try and find the best way to maximise what I get. I worked an additional 30 hours last month compared with the previous to try and up my take home ... €17 out of each of those additional hours went on tax, leaving me to take home just €5.

So, if working harder isn't a viable option to increase my salary, I guess I need to find out how to do it smarter.

My accounting and tax knowledge is very limited so I do appreciate your patience in your replies.
