Ibsen Venning Brixius I/S (IVB)

Ibsen Venning Brixius I/S (IVB) is a Danish consulting partnership led by partners Alexander Ibsen, Mille Venning and Sebastian Brixius, combining specialist skills in tax, real estate, accounting and investment. The firm provides integrated advisory services that span tax compliance, property transactions, investment analysis and financial accounting, enabling clients to handle complex financial and legal-adjacent matters from a single advisor.

IVB has developed a reputation for deep technical expertise in niche areas such as parental purchase of real estate, estate tax matters and company tax schemes, supported by practical experience in preparing deeds, rental contracts and tax accounts. Their advisers apply detailed, jurisdiction-specific knowledge of Danish tax and property rules when structuring transactions and reporting to the tax authorities.

The firm prioritizes a personal, dialogue-driven service model that emphasizes trust, clarity and holistic problem solving. IVB works directly with private clients, company owners and expats to deliver tailored solutions, and when specialist expertise beyond its scope is required, the firm leverages a network of external advisors to ensure clients receive comprehensive, practical outcomes.
