I am planing to move EU countries to start a company and apply for citizenship. Can you please kindly suggest me as per you experience , is Hungary is right place? I heard that tax is huge here.

And can you please give me a rough idea for all costing to start a company and apply for citizenship, living cost everything.

As my plan to save money as well, am I show my home ( rent or buy) as a business address?

Please kindly share ur knowledge about below costing or any other needfull.

1. Company Incorporation
2. Registered address ( may i use my home address ?)
3. Housing rent per year ( include current, internet, water, gas, TV, etc. everything)
4. Resident Permit application
5. Tax number, Social security number, Insurance
6. Business plan writing to submit
7. Food cost per person monthly ( on average )
8. Yearly tax

Is there any good firm can help or any other good person who can guide me.
