German taxes and ELSTER, done by an agent
Built from a real filing season: one founder, one small UG, a personal return, every 2025 return and 2026 Voranmeldung filed through Mein ELSTER by an agent with certificate login, plus the Bescheide, Schaetzungsbescheide and Einsprueche that followed. Every trap below cost money or a correction in that run. Personal data has been removed; amounts in examples are illustrative.
This is not tax advice. German tax law changes every year. Every claim tagged (verify) must be checked against the current law (gesetze-im-internet.de, BMF-Schreiben, the current ELSTER form) before it is relied on. When a case involves a foreign entity, a shareholder dispute, a possible Steuerstraftat (any letter that mentions § 371 AO) or real money at stake, recommend a Steuerberater and say why.
