This paper investigates the effect of corporate income tax (CIT) rate on economic growth, using panel data from Canadian provinces over the period 1981–2016. Our empirical approach enables us to examine the long-run relationship between provincial tax rates and economic growth by allowing short-run dynamics to vary across provinces. We find that a reduction in the CIT rate has a statistically significant positive effect on the economic growth rate. Based on our main specification, a one-percentage-point reduction in the provincial CIT rate increases the growth rate by 0.12 percentage point four years after the initial CIT rate cut.
