Abstract: This paper studies how tax legitimacy shapes resistance to taxation. We examine colonial Nigeria, where British authorities introduced broadly similar taxes under a common colonial regime but confronted sharply different pre-existing fiscal systems and sources of legitimacy. Using 40,852 colonial administrative documents, we apply large language models to construct measures of tax sentiment and tax complaints, and validate them against a human-coded subsample. In a spatial regression discontinuity design at the historical boundary of the Sokoto Caliphate, we find more negative tax sentiment and higher complaint rates in areas where colonial taxation displaced a centralized fiscal order rooted in established moral and religious authority. These patterns are consistent with contestation of the colonial state’s right to tax rather than differences in tax instruments or burden, enforcement, administrative capacity, or colonial public goods provision. We also document persistence today using Afrobarometer measures of tax legitimacy, including beliefs about whether the tax authority has the right to make people pay taxes. The findings identify legitimacy as a distinct determinant of tax resistance and a key constraint on fiscal capacity.
