The accounting under commercial law is codified in §§ 238 ff. HGB. The norms of commercial law have an influence on taxation via the principle of relevance Determination of profits (Tax balance; Accounting obligation; Accounting). The trade balance permeates large parts of tax law via the reverse and extended relevance.
Due to tax exemptions, however, breaches of the principle of the relevance of the commercial balance sheet for tax law are increasingly evident.
The international accounting regulations (IAS / IFRS) are becoming more and more important for the consolidated financial statements. For the commercial balance sheet of individual companies, there are now options for accounting according to IAS / IFRS in numerous countries.
