What about the financial penalties?
When it comes to assessing penalties against incorporated or unincorporated nonprofits for late filing or failure to file Form 990, the price tag is steep:

      $20 per day up to $10,000 or 5% of revenue (whichever is less) for organizations grossing under $100,000 or;

      $100 per day up to $50,000 for those grossing over $100,000.

Definitely not chump-change. In fact, it is enough to force the closure of many nonprofits.
