Final answer:
The primary role of the IRS Criminal Investigation Division is to uncover financial crimes related to tax evasion, particularly focusing on willful and intentional violations concerning the filing of income tax returns.
Step-by-step explanation:
The chief responsibility of the Criminal Investigation Division (CID) would typically revolve around investigating serious crimes such as organized crime, financial crime, cybercrime, and other criminal offenses. However, if we are referring specifically to an agency like the Internal Revenue Service (IRS) Criminal Investigation Division, the core responsibility is indeed very specialized.
The IRS CID primarily focuses on financial crimes relating to tax evasion and fraudulent tax filings, including the detection of taxpayers who willfully and intentionally violate their known legal duty of voluntarily filing an income tax return.
Although the IRS CID may at times engage in verifying the accuracy of tax returns or detecting fraud in public corporation's tax filings, these would be seen as supporting activities to the primary objective. To reduce the amount of tax evasion, the US government would need to allocate additional resources towards enforcement and monitoring, combating the substantial free riding that costs the Treasury billions annually.
