Good to see proactive proposals. In practice, it would be interesting to see whether this would have any real impact; people operating in the black economy are probably less concerned about being registered for tax and/or operating with proper licenses
The proposals include extending HMRC’s data gathering powers, forcing more business to register for tax purposes in order to access business services and licenses, and new penalties for compliance failings.
