# Taxing Efficiency Gains (The Efficiency Tax)

The organizational practice of treating time saved by technological efficiency as *spare capacity* to be immediately filled with more work. When employees use AI to automate tasks 'A and B,' organizations often respond by assigning tasks 'D, E, and F' rather than letting the employee focus on higher-value work 'C' or enjoy the recovered time. This is captured bluntly in [[quote-efficiency-tax]].

The result is a rational disincentive to reveal AI-driven productivity gains — formalized as [[claim-efficiency-tax-causes-hiding]] and as the **Workload Cost** in the [[framework-costs-of-ai-visibility]]. The direct remedy is [[action-explicit-saved-time-norms]]: publish explicit rules for how AI-saved time may be reinvested.

**Enrichment note:** The *label* 'efficiency tax' is original to this article. The underlying mechanism — employees withholding methods when they expect workload strain or defensive reactions — is directionally supported by adjacent knowledge-hiding research, even though no prior source uses this exact phrase.
