WinnerLex is a team of experienced tax lawyers in Ukraine with a strong track record in tax advisory, audit support, and litigation.
Ukrainian tax law, regulatory policy, and court practice evolve rapidly and often unpredictably — making tax issues a constant priority for businesses of all sizes.
Our tax practice is led by attorneys with hands-on experience working inside Ukrainian tax authorities. This gives us a deep understanding of how tax administration works in practice — and how to build effective dispute resolution strategies from the inside out.
We advise businesses — including large taxpayers — at every stage: before audits (tax due diligence, contract review, responding to authority inquiries)
and after (challenging tax assessment decisions). We also regularly represent clients during audits, ensuring inspectors act within the bounds of their legal authority.
WinnerLex has built a strong reputation as litigation-focused tax lawyers in Ukraine. Our track record includes successfully overturning complex tax assessments — including a UAH 180 million tax notification-decision — as well as participation in drafting tax legislation and running professional development seminars for tax lawyers and accountants across Ukraine.
