When is the tax return due date?
Can you let me know the date by which the tax return for 2012 is due?
The standard deadline for the 2012 tax return is 1 April. If you lived outside the Netherlands in 2012 for the whole year or part of the year the deadline is 1 July. If you haven‘t received an invitation to file a tax return a deadline is not applicable.
