KATA or KFT for a freelance English teacher?

1) If you have a KFT you are an employee. Your employee income taxes are listed here:

And the KFT has to make another 18% employer contribution for your social insurances and retirement. Total personal and company taxes for each employee (i.e. you) is about 52% of your income. And the KFT has to pay you a minimum wage (i.e. you can not just pay yourself 1 Forint). And any additional revenue from the company has a 10% company tax, and if paid out to you then is also taxed as income. And you have to put in 3 Million Forint into the KFT (can be done at company formation or over a few years) before you can withdraw any dividends.

2) There is a special entrepreneurial flat tax of about 35% on income (i.e. you can decrease this tax by writing off expenses from revenue).

3) And KATA which is a flat monthly payment (not a percentage) with a maximum revenue of 5 Million Forint. You can not write off any expenses.

Which of the above is best will require you doing the math given your expected income and expenses.
