Who We Are

Sarego Finance is a Kraków-based firm focused on accounting, tax and legal support for foreign-owned companies operating in Poland. Most of our clients are international founders and executives who do not have a local team in Poland.

We work as one integrated team: accounting, tax and law in one place. Our clients deal with one firm, not three unrelated providers passing files between each other.

We operate fully remote and paperless. All client communication is in English. We are KSeF-ready and handle VAT, CIT, payroll and corporate compliance for entities across Poland, coordinated from our office in Kraków.

Our legal work is carried out through Gostyński i Wspólnicy, a law firm affiliated with Sarego Finance and specialising in corporate and commercial law. The two teams work together on client matters from the start.
