Electricity tax enterprise definition and audit notice specificity for limitation period suspension

The Federal Court of Finance (BFH) ruled in favor of the taxpayer, ordering the lower court to reassess the case based on the interpretation of the statutory concept of "enterprise" for electricity tax benefits and holding that the tax assessment did not become time-barred because the specific audit notice did not sufficiently designate the audit's subject matter, thus failing to constitute a valid start of the external audit to trigger suspension of the limitation period. The dispute concerned the availability of electricity tax reductions for a power utility company and whether the tax authority’s subsequent assessment was precluded by the statute of limitations due to the timing and scope of a tax audit. The court clarified that for the limitation period to be interrupted by an external audit, the initial audit notice must precisely define the audit's scope; a generic notice that fails to specify the exact subject matter under review does not effectively commence the audit procedure for the purpose of suspending the assessment period under German tax procedure law.
