The Federal Fiscal Court (BFH) confirms strict requirements for vehicle tax exemptions for agricultural vehicles

The Federal Fiscal Court (BFH) has ruled that a partnership is not eligible for a motor vehicle tax exemption for its agricultural vehicles if it also uses them to transport produce to a biogas plant it operates (BFH, ruling of Dec. 18, 2024 – IV R 11/23). This ruling has far-reaching consequences for agricultural businesses engaged in secondary commercial activities.

Background of the Motor Vehicle Tax Exemption

Under Section 3(7) of the Motor Vehicle Tax Act (KraftStG), agricultural and forestry trailers are exempt from tax under certain conditions. This exemption applies if:

• the vehicles are used exclusively in agricultural or forestry operations, or
• transport is carried out for agricultural or forestry operations, provided that such transport begins or ends at such an operation.

Facts of the Case: Use of Agricultural Trailers for a Biogas Plant

In the underlying case, a GmbH & Co. KG grew silage corn and rye and simultaneously operated a biogas plant. The electricity produced was sold. All of the silage corn was used for energy production, while most of the rye was sold. The corn was transported to the biogas plant using two trailers, for which the company applied for a tax exemption.

The Main Customs Office rejected the application because the vehicles were not used exclusively for agricultural operations. Following an unsuccessful lawsuit, the Federal Fiscal Court (BFH) has now upheld this decision.

BFH Decision: No Tax Exemption for Commercial Use

The BFH clarified that the tax exemption is not automatically ruled out simply because the plaintiff is classified as a commercial enterprise under income tax law. Rather, the decisive factor is whether the vehicles were used exclusively for agricultural operations.

Since the trailers were also used to transport corn to the commercially operated biogas plant, there was no exclusive agricultural use. Thus, the requirement for a tax exemption was not met.

Consequences for Agricultural Businesses

The ruling makes it clear that agricultural businesses with secondary commercial activities must carefully examine how they use their vehicles. As soon as there is commercial use—such as for a biogas plant—the vehicle tax exemption no longer applies. Affected farmers should therefore reconsider their transport logistics to avoid tax disadvantages.

Conclusion

Agricultural vehicles are only exempt from vehicle tax if they are used exclusively for agricultural operations. As soon as a commercial activity comes into play, such as the operation of a biogas plant, the tax exemption may no longer apply. Businesses with mixed activities should seek tax advice to avoid potential tax liabilities.
