No idea, sorry. I don't know how big of a problem this is in practice in Denmark. I know that audits are performed on a national level. So I assume this would be less of an issue compared to countries where the health care system is very decentralized.
If you ever want to share and blur out information, I would love to see screen shots of the portals where all of this comes together. Everything is more expensive in Denmark. Does that VAT that you pay, get applied directly to the healthcare system?
We more or less only pay for prescription medicine (out of hospital) and dentist. And both of those two are highly subsidized by the government. VAT does not go directly into anything particular but is just a general income for the government.
