Strange, because that sounds reasonable but the reasoning doesn't actually work, does it?
Either "the law" can be trusted, and there's no point to deleting data after a cut-off date, or the reverse is true and you're no worse off getting caught deleting data.
I believe the law actually provides a middle ground. You're liable for tax fraud for X years, but you're allowed to delete the data after Y years. Since X > Y you make it much harder for the tax office to sue you if you delete data. Plus make it pointless for them to use their other investigative powers against you, which is in reality more important, especially for smaller firms.
