Tax law

Tax is about more than numbers – it’s about reputation, risk, and responsibility. In today’s regulatory landscape, expert legal advice is essential to navigate complex rules, manage exposure, and avoid costly and time-consuming disputes with the tax authorities.

When tax issues arise, the state can be a powerful adversary. Securing the right legal counsel from the outset is crucial. We have substantial experience representing clients in intricate tax and VAT matters – from audits and administrative appeals to full litigation against national and international tax authorities.

I find them knowledgeable and receive balanced responses. I collaborate with them in a way similar to a colleague, on a seamless basis.
