Africa has sustained gains in domestic resource mobilisation made since 2000, as tax revenues remained stable in 2016, according to Revenue Statistics in Africa 2018. Providing internationally comparable data for 21 participating countries, the report finds that the average tax-to-GDP ratio was 18.2% in 2016, the same level as in 2015, which represents a strong improvement from 13.1% in 2000.
The third edition of Revenue Statistics in Africa, released today in Paris during the 18th International Economic Forum on Africa, shows that tax-to-GDP ratios varied widely across African countries, ranging from 7.6% in the Democratic Republic of the Congo to 29.4% in Tunisia in 2016. Six countries -Mauritius, Morocco, Senegal, South Africa, Togo and Tunisia- had tax-to-GDP ratios greater than or equal to 20% in 2016. In comparison, the average tax-to-GDP ratio for Latin America and the Caribbean was 22.7% and 34.3% for OECD countries in 2016.
Revenue Statistics in Africa is a joint initiative between the African Tax Administration Forum (ATAF), the African Union Commission (AUC) and the Organisation for Economic Co-operation and Development (OECD) and its Development Centre, with the support of the European Union.
The publication, which now covers 21 countries, shows that revenue trends are mixed. Between 2015 and 2016, the tax-to-GDP ratios of 11 countries increased while those of 10 countries in the sample decreased. Botswana registered the highest increase (1.3 percentage points) followed by Mali (1.2 percentage points). The largest decreases (of over 2.0 percentage points) occurred in the Democratic Republic of the Congo and Niger. The changes in tax-to-GDP ratios were primarily due to economic factors. Declines in oil prices coupled with lower activity among mining and oil companies contributed to the decreases in the Democratic Republic of the Congo and Niger, while a significant increase in the sale of diamonds in Botswana has increased revenues. In contrast, the increased tax-to-GDP ratio in Mali is partly explained by improvements to tax administration.
African economies continue to rely heavily on taxes on goods and services, which accounted for 54.6% of total tax revenues in the Africa (21) average. Value-added taxes (VAT) alone accounted for 29.3% of revenues. However, the contribution of income taxes is increasing: taxes on income and profits accounted for 34.3% of total revenues across the Africa (21) in 2016 and have contributed the most to growth in tax revenues since 2000, increasing by 2.6% of GDP to reach 6.2% of GDP in 2016. Corporate income tax revenue increased by 1.4 percentage points over this period to 2.8% of GDP, while revenue from personal income tax rose from 2.1% to 3.0% of GDP in 2016, a historic high.
The report also contains data on non-tax revenues, which continued to decline across the 21 countries on average in 2016 but remain an important source of income in certain countries. These revenues, which include income from natural resources and grants, exceeded 5% of GDP in nine of the 21 countries.
Revenue Statistics in Africa is an important part of the African Union’s Strategy for the Harmonization of Statistics in Africa (SHaSA) and is aligned with the African Union’s Agenda 2063 and SDG 17.1. This edition contains a special chapter on SHaSA, identifying its approach to establishing an efficient statistical system that covers the political, economic, social, environmental and cultural development and integration of Africa, as well as the role of Revenue Statistics in Africa in this strategy.
Tax revenues as a percentage of GDP
The Africa (21) average tax-to-GDP ratio was 18.2% in 2016, which is 5.0 percentage points higher than in 2000 but unchanged from 2015. In 2016, tax-to-GDP ratios ranged from 7.6% in the Democratic Republic of the Congo to 29.4% in Tunisia. Six countries (Mauritius, Morocco, Senegal, South Africa, Togo and Tunisia) had tax-to-GDP ratios greater than or equal to 20% in 2016. The change in the tax-to-GDP ratio since 2000 is comparable with the increase in the LAC region (4.7 percentage points) and significantly stronger than growth amongst OECD countries over the same period (0.4 percentage points). Between 2015 and 2016, the tax-to-GDP ratios of 11 countries increased while those of 10 countries in the sample decreased. This contrasts with 2015, when the Africa (21) tax-to-GDP ratio increased by 0.5 percentage points from the previous year on average and in 15 of the 21 countries.
VAT revenue as a percentage of GDP in the Africa (21) increased by 2.0 percentage points from 2000, to 5.3% in 2016. VAT revenue accounted for the highest share of tax revenues in 2016 at 29.3%, an increase of 4.9 percentage points from 2000. The share of taxes on trade has fallen from 17.9% of total tax revenue to 11.6% over the same period. Revenue from income taxes contributed the most to growth in the average tax-to-GDP ratio of the Africa (21) between 2000 and 2016, increasing by 2.6% of GDP over this period to reach 6.2% of GDP in 2016. On average across the Africa (21), corporate income tax revenue increased by 1.4 percentage points – from 1.4% to 2.8% of GDP – between 2000 and 2016. The Africa (21) average tax structure is similar to that of LAC countries, although social security contributions in LAC are, on average, considerably higher. The Africa (21) average share of personal income tax (PIT) revenues to total tax revenue was 15.8% in 2016, lower than the OECD average (24.4%) but higher than the LAC average (9.7%). Non-tax revenues were equivalent to at least 5% of GDP in nine of the 21 countries in 2016. Of the 21 countries, all but four had lower non-tax revenues as a proportion of GDP in 2016 than in 2015.
