MDDP

What MDDP does

MDDP (full legal name: MDDP Michalik Dłuska Dziedzic i Partnerzy Spółka doradztwa podatkowego spółka akcyjna) is a Warsaw-headquartered, privately-held Polish tax advisory firm founded in 2004 that delivers comprehensive tax consulting across 26 service lines organized into three groups: core tax (VAT, international tax, transfer pricing, CIT, PIT, customs, real estate tax), specialized advisory (green taxes, ESG, investment funds, private clients, transaction advisory, tax litigation), and compliance/adjacent services (local government, tax reliefs, valuations, withholding tax). The firm complements its human advisory with internally developed digital tools, notably the SMART.TP and SMART.TP-R applications for transfer pricing documentation and reporting, and a Tech Tax – Work Smart AI-assisted blog.

MDDP serves enterprise and mid-market clients across ten vertical segments including construction, real estate, energy and renewables, financial services/FinTech, e-commerce, technology, defense, local government, sports, and influencer marketing. Its client roster features prominent names in Polish real estate (Immobel, Adventum Group, Yareal, Griffin Premium RE.., Echo Prime) and cross-border investors (Irish ICAV funds, Amundi Real Estate, South Korean institutional capital). The firm has secured precedent-setting rulings before the Court of Justice of the EU — including SAWP (C-37/16), Kronospan (C-222/09), Aspiro (C-40/15), and the MDDP case (C-319/12) — and is part of the ETL GLOBAL international network, with dedicated German, Latin American & Iberian, and Ukrainian Desks.

The business operates on a quote-based professional services model, with partner-led engagement teams delivering fee-for-service advisory. Senior partners and tax advisors handle client relationships directly, supported by a thought-leadership-driven demand generation engine spanning specialized blogs, a Knowledge Platform, webinars, the Tax Everest academic competition, and active social media presence. A wholly-owned subsidiary, MDDP Sp. z o.o. Finanse i Księgowość sp.k., extends the offering into accounting and payroll outsourcing, while an integrated partnership with Osborne Clarke provides adjacent legal advisory capability. The firm employs 251-500 staff, is owned by its partners, and reports no parent company or public listing.
