3.2.2. Evolution of income for Corporation Tax

Net Corporation Tax revenues increased by 5% in 2016, 1,029 million euros more than in 2015. The impact of the regulatory changes is estimated at 1,047 million, and therefore, in the absence of any changes, revenue has remained stable. Growth is concentrated in payments by instalment, which increased by 8.8 percent (reduced to 3.5 percent if we remove the regulatory impacts). Withholdings over capital gains decreased (due to the reduction in rates and the drop in revenues) and the total tax liability was more negative than in 2015 (due to the 8.2 percent rise in refunds filed, as a result of the refunds requested in the 2015 campaign and, above all, to the higher rate of realisation).
