Obviously things get more complicated once you start hiring other people but the government does a good job of trying to streamline things compared to France.
Well, actually I didn't do anything because you literally have nothing to do. You just have the right to do some business on your own (but of course there are official companies of you want to get bigger).
Just when you start getting money, you have to inform the tax office, so they can give you the form next year.
Honestly, it wasn't so hard, and I can honestly say that I made it a little easier. The hardest part was taxes, and the honest solution is "hire a tax advisor, pay 300€ a year, be done with it".
The biggest problem for me is the cost of health insurance. As a self-employed person, you pay double. I pay 850€ a month in health insurance, and 550€ a month in rent. The fix is to switch to private health insurance, but that has its own caveats.
Here's an overview of what must be done: https://allaboutberlin.com/guides/start-a-business-in-german...

What do you mean, pay double? If you mean that, with regular employment, your "employer pays half" - that is just an accounting trick and you actually pay all of it.
For those who are curious, I wrote a plain English introduction to German health insurance: https://allaboutberlin.com/guides/german-health-insurance
There is a total cost for employer for a particular employee and the take-home pay for that employee. Where between those two we put a number that's called "your net income" is just arbitrary convention.
Employer knows how much the total cost will be when they negotiate the salary. It's all the same to them if the entire amount goes to you personally and then you use it to pay health insurance, or they first pay some of that amount to health insurance and then give the rest to you.
Ireland constantly pokes the tops of indexes that rank the ease of doing business across the world.
Current problems include the unattractiveness of using equity as a payment tool -- this only affects startups though.
Employing people: https://www.gov.uk/employing-staff (register with tax office, pay 13.8% of their pay over £166/w as national insurance. Very small employers don't have to register with PAYE: https://www.gov.uk/paye-for-employers
Usually you delegate that to some company like Sage.
Giving them shares or share options is potentially much more complicated, but by that point you'll retain an accountant for the purpose.
The big nightmares are visas (of any kind) and bank accounts. Small business banking doesn't have "consumer protection", and can come with all sorts of fees and predatory lending practices.
Next level would be incorporating. The process is easy. Can be done online in a few minutes.
Taxes become more complicated. For a small one to three person company expect to pay about 2-5K annually to a professional accountant.
Corporate tax rate is 15% under 500K of revenue in Ontario. It varies province by province. Quebec as I understand is higher and also more complicated as they have their own tax system separate.
Keep in mind thought that "starting" the business is one thing. How easy it it to find investments, opportunities and make it sustainable is a different question.
