This one might be so specific, but I will again ask another question, I am getting advantage of %30 tax ruling right now and I still have 3 years in addition. Is there any risk to lose this advantage after I started to gain additional income from my side business?

Another question , if I cannot find any client within one year and not able to provide any income from my own business Will I be subject to any penalties due to the inactivity of my own business?

Yes , I will start as a sole proprietorship. What is the best way to manage/follow this "taxing" topics ? I assume , I need to declare income of my own business separately . I am getting my salary(net) after deduction of the required tax amounts from my current employer . How the tax authorities will manage additional income that comes from my own business? What is the main logic behind that?

Hello , I am considering working as ZZP to gain extra income in addition to my full-time job. For a while , I am investigating everything about being ZZP in Netherlands and sometimes I am losing myself within a lot of different topics specially that ones related to "Tax" and "Regulation" topics. What I want to know is , Is there any profit/income limit that I need to reach within my first year to keep my company running ? I do not have any "fixed" client right now and I am planning to find some customers via famous "freelance job sites".I want to do experience this journey within a "smooth" scope in addition to my full time job. Could you please give me some information about this topic ? Any help/comment will be appreciated . Kind regards. Kutay.
