Seeking English-speaking accountant: Cross-border tax, A1 certificate & "Egyéni vállalkozó" setup

Dear all,

I am a dual citizen recently relocated to Budapest. Since I am still learning the language, I am looking for an English-speaking accountant/tax advisor to assist me with my specific tax situation and compliance.

My situation includes:

- Hungarian Employment: I am currently employed at a Hungarian university.

- Freelance Business: I currently have a sole proprietorship in another EU country (writing/consulting). I want to close the foreign firm and transition this to a Hungarian "Egyéni vállalkozó" (sole trader) setup to streamline my taxes and avoid double taxation. I need advice on whether Flat-rate taxation (Átalányadó) is the best fit for me.

- Cross-border Remote Work: I am likely to take on a part-time remote employment with a foreign university. I need guidance on social security belonging and help applying for the A1 certificate.

- Sale of Assets: I have some private sales of assets from abroad that need to be correctly reported in my Hungarian tax return.

I am looking for someone who is comfortable with EU double taxation treaties and international social security rules.

If you can assist or recommend someone, please reach out via e-mail.

Best,
