On July 27-28, Colombia hosted the first ministerial summit for sustainable, inclusive, and equitable global taxation, with the support of Brazil and Chile. The choice of venue is not coincidental: it reflects Colombia’s commitment to tackling poverty and inequality through progressive taxes.
The Colombian government’s flagship tax reform, spearheaded by the finance ministry under my direction and approved by Colombia’s congress in late 2022, is a prime example of this commitment. But, following its implementation, our focus must shift to improving tax progressivity across Latin America and the Caribbean (LAC), which remains among the world’s most economically unequal regions.
Latin American countries suffer from staggering income disparities, with the top 10 per cent of earners making 22 times more than the poorest 10 per cent and the top 1 per cent accounting for 21 per cent of the region’s total income. Wealth inequality is even more pronounced, as the region’s wealthiest 10 per cent own 77 per cent of total household wealth, compared to less than 1 per cent for the bottom 50 per cent.
LAC countries also share an entrenched, regressive tax system, reflecting their longstanding failure to tax high incomes, particularly capital income. Moreover, widespread tax avoidance and evasion have deprived governments of the resources they need to increase social spending and mitigate the effects of income inequality.
While aggressive tax competition between countries has been widely hailed as a boon for foreign direct investment and economic growth, the evidence shows that tax incentives and privileges attract financial flows but do not increase real investment, which tends to be driven by other factors such as the quality of institutions, the skills of the workforce, and infrastructure. Misguided notions that incentivise relentless tax competition between countries must be abandoned in favor of new growth policies that rely on greater global coordination between tax authorities.
LAC also shares a common frustration with how international tax-reform negotiations have been conducted so far. There is very little disagreement that the global tax system is outdated and unable to adapt to the realities of twenty-first-century business models. Multinational corporations have become adept at setting up shell companies to shift their profits to tax havens. This problem has been exacerbated by the advent of the digital economy, which has made it far easier for companies and wealthy individuals to avoid paying their fair share.
To address some of the most egregious tax-avoidance strategies used by multinational companies, the G20 and the OECD launched the Base Erosion and Profit Shifting initiative, which culminated in a package of reforms endorsed by 138 countries and jurisdictions. But early hopes that this process would lead to comprehensive reforms have been shattered. Despite some innovative elements, the measures outlined in the OECD’s Pillar Two global tax deal might even deepen existing inequalities between countries.
While Pillar Two’s 15 per cent global minimum corporate tax rate is innovative and promising, its current structure favors countries in the Global North, where the world’s largest corporations are headquartered, and tax havens. The current deal enables these countries to impose the minimum tax on profits earned in the Global South, thereby collecting taxes on profits that should not have been diverted in the first place.
Moreover, the 15 per cent minimum corporate tax rate is well below the Latin American average, which currently stands at 24 per cent. It is also lower than the 25 per cent minimum rate proposed by the Independent Commission for the Reform of International Corporate Taxation, of which I am a member alongside colleagues including Joseph E. Stiglitz, Jayati Ghosh and Thomas Piketty.
This disappointing outcome is partly the result of LAC countries’ inability to approach multilateral negotiations with a strong and united voice. However, it is important to note that the frustration is not limited to the region: African countries have also called for the United Nations, rather than the OECD, to take the lead in negotiations to reform the international tax system.
To achieve fairer regulatory frameworks that better represent the Global South, we must ensure that international governance processes are transparent and equitable. The upcoming summit in Cartagena marks the first step toward changing how LAC countries approach multilateral negotiations to establish more effective taxation across the region. The conference, which is supported by the UN Economic Commission for Latin America and the Caribbean and includes 16 participating countries, is the result of a lengthy preparatory process characterised by active engagement with the private sector, academia and civil society.
This historic inaugural summit, one hopes, served as a platform for collaboration between the region’s governments, enabling us to defend our shared interests, stop competing on tax rates to attract foreign investment and develop a framework for taxing digital services that aligns with our needs. With inequality and tax avoidance on the rise, LAC governments must forge an equitable future based on the principle of shared prosperity.
