What are the odds of Feds finding out employer offers HC while employee uses ACA instead?

5. Some things to keep in mind....

I base this on my limited knowledge after working on IRS computer systems for a long time - However it has been almost 20 years since I retired.

There are two primary components to our IRS system. An "input" entity and a "compliance" entity. At any of the various IRS offices around the country they have a very large physical presence usually at two separate distinct locations.

Any forms that are submitted to the IRS... are loaded into their databases, usually digitally, and basic math checks are performed. About a year later the work of the compliance center begins....there is an automated match done comparing forms received and forms submitted, if you get my drift.

For "flags" that come up then there is human intervention. In most cases an automated letter is generated and mailed for discrepancies. For egregious differences then it is possible to go into the audit cycle which has various levels of intervention.

Bottom line - computers do most of the verification.
