Early tax return filers have been punished rather than rewarded by the Dutch tax office, as a computer glitch meant all their information was deleted.
At least 730,000 people will now have to resubmit their 2007 tax returns.
No backups were made of the electronically-filed returns, and the only information to survive was the social security numbers of those affected.
The Dutch tax office has been struggling with IT problems since last year, when 400,000 companies had to resubmit payroll details because of a software fault.
The Auditor-General already noticed the aging IT systems at the rental and health care section earlier this year, but losing 730,000 returns is without doubt the worst hiccup in the tax office's battered IT history.
