Deadline for IB declaration now December 10th
Last weekend the portal MijnCN was down. This was due to maintenance work, which unfortunately ran over a day.
In a reminder that was sent to a group of taxpayers, November 11 was set as the deadline to file an income tax (IB) return. Due to maintenance, they could not use MijnCN this weekend.
The Belastingdienst CN now gives these taxpayers until December 10th to file their income tax return.
