Tech Hiccup Halts E-filing at Multiple Tax Offices

Disruption at Financial Institutions' Operations Due to Technical Glitch - Significant technological disruption at financial headquarters

Hey there! Got some news that might impact your tax filing plans. A technical issue has knocked out e-filing services at several tax offices across various federal states, including Schleswig-Holstein, Hamburg, Lower Saxony, Bremen, Mecklenburg-Vorpommern, and Saxony-Anhalt. That's quite a cluster, huh?

According to the latest scoop, around 120 tax offices are currently in the dark, with the Ministry folks in Kiel and Bremen spilling the beans. The problem stems from a network glitch rather than a sneaky cyberattack, a spokeswoman clarified. This network snafu has yanked the plug on access to tax procedure software, making it nigh impossible to process tax returns and objections at the moment.

The exact duration of this tech troubleshooting is anybody's guess. While things look dicey, citizens can still get general tax information from the ministries. As for specific inquiries, you'll just have to bear with it for now. The electronic submission of tax returns via Elster is still an option, thankfully.

On a slightly brighter note, partial service restoration has been reported thanks to some server restarts. The spokeswoman for the Lower Saxony tax office hinted at more improvements, so let's keep our fingers crossed!

For the record, this technical outage kicked off at a Dataport data center in Germany on May 7, 2025, around 11:30 AM local time. By May 9, partial functionality had been restored, and they're working on a permanent fix, including hardware replacement and testing. So, expect this network hiccup to last beyond May 12, depending on how things pan out.

Just thought you should know! Stay tuned for updates, and in the meantime, keep those tax questions simmering. Good luck!
