The opening
balance sheet is the asset overview of a company prepared at the start of a new
fiscal year, upon the establishment of a company, or following
transformation,
merger, or
insolvency proceedings. As a central component of accounting and financial reporting according to the HGB, it contains all assets and liabilities, serves the commercial registry as proof of existing equity, and forms the basis for all subsequent business transactions. Founders of a GmbH, UG, or AG, as well as
partnerships transitioning into a corporation, must submit the opening balance sheet to the registry court in a timely manner; however, unlike the
annual financial statement, it is not published. The obligation to prepare also applies to acquiring companies after a merger and to the
insolvency administrator upon the opening of proceedings. A correct opening balance sheet ensures
compliance with essential Generally Accepted Accounting Principles (GAAP), commercial and tax regulations, minimizes liability risks, and facilitates audits. Tax advisors recommend using accounting software or ERP systems during the founding process to optimize valuation, documentation, and electronic submission. Preparing the opening balance sheet creates transparency, strengthens the trust of investors, banks, and business partners, and lays the foundation for sustainable business success.
