Tax Disputes – A Key Part of Corporate Financial Administration

Related services

Disagreements that arise in the tax assessment and in tax audits often lead to lengthy appeal processes that sap time and resources from a company’s management and financial department. We advocate a pre-emptive approach to avoid problems through careful analysis of tax issues, diligent reporting and smooth communication with the tax authorities.

Should you nevertheless find yourself facing a tax dispute, whether domestic or international in nature, you will be able to rely on our renowned dispute resolution team to defend your interests. We will also provide you with the best possible assistance in handling tax complaint processes if your company is subject to a tax audit or if the Finnish Tax Administration intervenes in any arrangements at a later date.

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.
