Problem
Finding the right Finanzamt should be simple, but the process is often fragmented across official pages, postcode tables, and district-specific wording.
For people registering, filing, moving, or dealing with tax paperwork in Germany, the real question is practical: which office is responsible for me, and what do I do next?
Approach
Welches Finanzamt? puts the address or postcode first, then resolves the relevant tax office into a clean result with the details people actually need.
The interface was designed as a fast utility rather than a directory: minimal form input, clear result hierarchy, and mobile-friendly pages for people checking while filling out paperwork.
Search and content structure were treated as part of the product, so each lookup path can support discoverability while still feeling direct to the user.
Outcome
A simple civic-tech tool that turns a bureaucratic lookup into a confident answer.
People can find the correct Finanzamt in seconds, understand why it applies to them, and move on with the next step instead of opening more tabs.
