Should I register business and pay tax?

Hello,

So, I'm a little worried about tax. There is 2 options for me.

First is, register a company and pay 20% tax from profit, have to do all accounting and use the documents/invoices online to remove the capital.

Second, register as a business only and pay 14% of all revenues.

The first option, if I take profit of just 20%, I would pay 20% of 20% which is 4%, and second option I pay 14%!.

But with a company I have to do accounting, with business, I just pay given figure, that is 14%…
