+administration FAQ on tax shelter for scaleups (translated to english):
+
+   31. A royal decree (to be issued) will determine the manner in which
+       evidence is to be provided and that the proof that the company in
+       growth fulfills the criterion of growth of turnover or full-time
+       equivalents.
+
+In the attestation template from the administration, there is currently
+some information on annual sales and number of employee for the past two
+years before the fiscal year. It’s a lot of information to add to the
+declaration. Since the legal situation seems still uncertain, we might
+wait before adding this information in the report.
