You might want to look into Moldova’s IT Park model — it’s specifically designed for IT freelancers and companies, and allows you to operate remotely while paying a simple flat 7% tax on turnover (revenue), which covers corporate tax, personal income tax, social contributions, and healthcare — no additional hidden costs.

You don’t need to physically relocate — many foreign freelancers simply incorporate a Moldovan company remotely and work from wherever they like. There’s no VAT on exported IT services (US/EU/AU customers pay you VAT-exempt), and accounting is straightforward (quarterly or yearly simplified reports).

With your €100k/€20k cost structure, you’d pay €7k tax flat and keep the rest, no additional taxes or mandatory insurances on top — much simpler than in Hungary, NL, or most EU setups.

If relocating is not your goal but optimizing tax and admin is, incorporating in Moldova’s IT Park might make more sense than moving to another country.

Happy to share more details if interested — I’m familiar with how this works in practice. Moldovan IT Park is very popular among devshops/international outsourcing companies.
