Is an office container subject to property tax?

Property tax is one of the costs associated with running a business. It applies not only to buildings and business premises, but also to buildings and land. 

Pursuant to the Act on Local Taxes and Fees, the real estate tax covers buildings or their parts as well as structures or their parts constituting separate objects of ownership or possession. Under the concept building it is understood as a building structure with a closed body, permanently connected to the ground, which can be used throughout the year. On the other hand, a structure is understood as a structure that is not a building, permanently attached to land or water.

Office container is a closed building that can be used all year round. But is it permanently attached to the land? There is no clear answer to this question. It all depends on how the office container was installed and how long it is to be used in a given place.

Tax authorities and administrative courts take different positions on classification office containers as buildings or structures. Some believe that an office container is permanently attached to the ground if it is placed on foundations or other structural elements that prevent it from being moved without damage. Others believe that an office container is permanently attached to the ground if it is intended for long-term use in a given place and it is not possible to move it without incurring significant costs.

For example, the Supreme Administrative Court ruled in its judgment of March 14, 2019, file ref. II FSK 230/17, that an office container constitutes a building subject to real estate tax if it is placed on concrete foundation blocks and connected to a permanent electrical, water and sewage system. On the other hand, the Provincial Administrative Court in Warsaw ruled in the judgment of February 18, 2020, file ref. III SA/Wa 1807/19, that an office container is not a building subject to real estate tax if it is placed on metal legs and is not connected to a permanent electrical, water and sewage system.
