Description
German tax software for UK buyers
Living in the UK but still need to file a tax return in Germany, perhaps because you let out a flat there or run a business across the Channel? BUHL tax 2026 Professional is the extended edition of BUHL's German tax software for tax year 2025, covering up to 3 users on 1 PC.
One thing to be clear about before you order: the software is in German only and built for the German tax and banking system. It will not complete a UK Self Assessment return.
Key features
