State tax agencies use opaque AI for audit selection without oversight
State tax agencies in California and New York use automated AI systems for audit selection that bypass state oversight requirements. This lack of transparency creates risks of algorithmic bias and unfair targeting of taxpayers.
Agencies utilize narrow definitions of AI to bypass statutory transparency and bias-testing requirements.

What happened
State tax agencies in California and New York have implemented machine learning systems to identify taxpayers for audits. These systems operate without independent oversight or external validation for bias and accuracy. Consequently, taxpayers risk being wrongly flagged for audits due to opaque models that may perpetuate historical biases.
What broke inside the model
- 01 · TriggerA prompt pushes against a deployment boundary.
- 02 · Model stepThe model produces the disallowed output.
- 03 · Control gapNo enforcement blocks it at generation time.
- 04 · FailureThe output crosses the policy line.
- 05 · ConsequenceA limit the business set is breached in public.
The output crosses a policy boundary the deployment had defined.
The failure is a systemic lack of governance where agencies utilize narrow definitions of AI to bypass transparency laws. Specifically, the systems lack mandatory bias testing and impact assessments, allowing algorithmic errors to go undetected.

Realm compares what the model is about to output or do against the policy that governs the deployment, in real time, and can deny or redact the action before it takes effect, which is the gap an after-the-fact review never closes in time.
