Honestly - stay at home and go offshore with your business
Would be legal in CZ (no CFC rules)! In SK probably not.
Bulgaria and Romania are both good options. The Baltic countries too. Depends all on your goals.
Malta is overrated and overpriced. And the 6/7 tax cashback brings you just in the next trouble. You need it to transfer is out of Malta. And after that you need to pay tax in the country of your residence. Incorporation cost you about 2-4k, accounting etc maybe 300-400 a month. Banks become paranoid.
One cool option if you want to stay in the EU ... Relocate to Cyprus (for just 60 days a year). They have an ultra interesting Non-Dom scheme (Cyprus HNWI).
My best advice, leave Europe. Go to Thailand. Nice country, great weather, friendly people, lots of fun and pretty good infrastructure.
The best is the tax regime. You can be resident without paying any tax if you do not generate income in Thailand and the money which you transfer to Thailand for rent, living etc must be generated in the year before.
Means, send yourself your complete (offshore company) income from 2017 in January 2018 and it will be completely tax-free and 100% compliant!
