Thedy & Partners

What Thedy & Partners does

Thedy & Partners is a Warsaw-based professional services firm founded in 2015 that delivers tax advisory, transaction consulting, financial advisory, accounting, grants/incentives, and regulatory advisory services to large enterprises, private equity funds, and mid-market companies operating in Poland. Service lines span CIT, PIT, VAT, excise duty, transfer pricing, real estate tax, tax litigation, M&A transaction structuring, Polish Investment Zone permits, and emerging EU regulatory frameworks including CBAM, PPWR, EUDR, and supply chain compliance. The firm was strengthened in 2017 through a merger with Nielepkowicz & Partners, a specialized real estate tax practice that contributed the current real estate tax leadership.

The firm operates from four Polish offices (Warsaw headquarters plus regional branches in Katowice, Poznań, and Wrocław) and is staffed entirely by licensed tax advisors. All eight partners hold Big4 pedigrees, predominantly Arthur Andersen and Ernst & Young. The partnership includes specialists individually recognized in Polish tax rankings — Michał Nielepkowicz (real estate tax, Rzeczpospolita's Best Tax Advisor in PON), Andrzej Kapczuk (VAT), Łukasz Kupryjańczyk (M&A), Adam Allen (grants and incentives, with PLN 300 million+ secured and 80+ SSE permits), and Managing Partner Michał Thedy (transactions, ex-Ernst & Young Director). Director Michał Parafiniuk leads the financial advisory practice with CFA and prior CFO/Finance Director experience at PE-backed companies (SMYK/Bridgepoint, CTL Logistics, Budimex).

Go-to-market is partner-led and relationship-driven, with senior advisors reaching enterprise clients directly and the website publishing individual partner email contacts. The firm ranks 14th–15th by revenue and 10th by number of licensed tax advisors in Poland's two principal 2026 industry rankings (Rzeczpospolita and Dziennik Gazeta Prawna). Revenue is generated exclusively through engagement-based professional fees — there is no technology product, no software platform, and no AI/ML infrastructure underlying delivery.
