MDR system maintenance: 30 September evening to 1 October
Poland’s MDR taxpayer application may be unavailable from 19:00 on 30 September until 08:00 on 1 October during maintenance.
Maintenance affecting Poland’s MDR taxpayer application is announced for today, 30 September 2026. According to podatki.gov.pl, it may be unavailable from 19:00 until 08:00 on 1 October.
The announced maintenance window
The notice was published on 25 September. It concerns MDR and does not establish that every electronic tax service will close or that the entire portal has failed.
Identify the affected application
If you plan to use the application this evening, allow for the stated window. First confirm that your document is actually submitted through the affected service. This is especially useful where different staff handle different reporting obligations.
Keep submission confirmations
After completing an operation, retain the available confirmation and check the document’s status. Saving a draft is not the same as completing submission. If an error appears, record its wording and time to help with later clarification.
The maintenance notice does not itself announce an extension of tax deadlines. Ask your accounting team or the responsible authority about a specific obligation. Once the scheduled work ends, check the service’s current status.
