Abstract

Determining the optimal tax burden that maximizes compliance and revenue remains a major challenge in developing countries, partly due to the literature's focus on linear tax-compliance relationships. Using firm-level data from Ghana and an instrumental variable approach, this paper finds a nonlinear relationship: compliance rises with higher taxes up to a threshold of 45%, beyond which it declines. This threshold, more than double the average tax burden of 21%, varies by firm size and formality—medium-large firms (30%), micro (46%), small (49%), formal (41%), and semi-formal (46%).
