OmaVero: a system upgrade for the Finnish Tax Administration

Together with the US software company FAST Enterprise, we implemented a system upgrade for the Finnish Tax Administration, replacing up to 70 end-of-lifecycle tax-related IT systems with a single off-the-shelf software package. The Valmis project, which was the largest transformation project in the history of the Finnish Tax Administration, overhauled the entire Finnish tax system between 2013 and 2020.

The Finnish Tax Administration faced the challenge of managing dozens of separate tax systems and technology solutions, that in many cases were already outdated. The goal was to have a system that was easier to maintain, faster to develop and more cost-efficient.

Additionally, the project aimed to build a new type of interface that would allow citizens and businesses to manage and administer their tax affairs digitally and seamlessly with one single login.


The project involved a wide range of experts from many different fields. We worked closely with our partner FAST, the Finnish Tax Administration and various stakeholders to build a complete solution that streamlines the customer experience and brings more efficiency to the Tax Administration’s operations. We implemented the GenTax product from the FAST Enterprise to enable centralized management of all tax-related activities through a single system.

The new system allows people to complete a number of routines, including file income tax returns for corporations or claim benefits under a joint administration. Additionally, it is also possible to request a prepayment or additional prepayment for a corporation, file self-assessed tax returns, request a payment arrangement, request a tax debt certificate, file gift tax returns, and much more.

Impact – Project of the year

The Tax Administration runs Finland’s most important service. Reforming the tax system has therefore been a large, complex project that has been a great success. The project was delivered on time, costs were kept under control and the final result exceeded expectations. Valmis also won the 2020 Project of the Year award.

How proactive public services can contribute to a more socially just and equitable society

Proactive public services have the potential to transform societies. Examples of what a PPS-enabled future can look like include tax declarations that take seconds, a new driver’s license dropped into your mailbox when an expiration date gets close, or social benefits that get automatically deposited into your bank account.
