Potential Merchant : Thinking about Bitcoin

I am thinking about accepting Bitcoin as a merchant.

I am worried about dirty bitcoins, bitcoins originating from sanctioned countries, proceeds of hacking / crime etc. Is there a way to check for this before accepting Bitcoin?

Keeping in mind that there will be:
The tax man
Financial conduct authority
Data Protection Agency

and a host of other 3 letter agencies auditing me and I hate hassle I want to be cleaner than the clean. (heart issues, no stress, doctor's orders)
