Tax Processes

We provide comprehensive advice in all tax processes: tax disputes, tax audits and tax crimes.

It takes time, money and effort to solve tax disputes. Our tax experts support you in planning your business and taxation. We help you to avoid difficulties before they occur and, if necessary, support you in solving tax disputes.

Any taxpayer can become the subject of a tax audit. In a tax audit, the taxpayer’s transactions and taxation are examined more thoroughly compared to other tax supervisory processes. This is why a tax audit may seem cumbersome even if the taxpayer had diligently observed all tax rules and regulations.

A tax audit may raise suspicions of a potential tax crime. To ensure the best possible support for your matter and to avoid any misunderstandings and confusions already at the early stages of the process, it is crucial to consult an expert as early as possible particularly in tax audit and tax crime processes.

Our tax experts have a versatile background in handling a wide variety of tax processes both as counsel and as a representative of the Finnish Tax Administration and administrative courts. In tax audit and tax crime matters, we assist our clients in cooperation with our recognised dispute and criminal procedure lawyers.

Careful planning is often the key to a successful arrangement, and it is possible to get definitive answers to questions that are open to interpretation through a ruling of the Finnish Tax Administration. The Tax Administration has recently focused on improving cooperation with its customers and has encouraged companies to actively apply for written preliminary rulings and even engage in preliminary discussions concerning more challenging arrangements. We have assisted Finnair and Municipality Finance , among others, in arrangements that involved significant income tax questions, which we resolved by applying for preliminary rulings. In the following, we describe a few of our recent case references involving preliminary rulings.
