The IRS reports “enforcement” revenue more routinely than it reports “service” revenues from alternative treatments. As a result, it may be more likely to use coercive treatments than to implement effective alternatives that rely on the latest behavioral science insights (e.g., insights from psychology and behavioral economics). However, the taxpayer’s right to privacy, which includes the right to expect that any IRS inquiry or enforcement action will “be no more intrusive than necessary,” require the IRS to try alternative treatments before resorting to coercion. Further, when coercion is unnecessary, it wastes resources, burdens taxpayers and probably reduces voluntary compliance and overall tax revenue indirectly (i.e., in future years or due from other taxpayers).
