A raid is a lot of work and only happens when you know you find something.

For 99,9% of companies, you get audited every 5—25 years by getting a visit from your local tax authority.

Remember: Small/medium companies have comparable companies and you can easily spot the tax dodgers. Or tax dodging is unofficially tolerated to some degree — think restaurants only accepting cash.

Most companies are not as blatantly illegal as Uber..
