SMALL TAXPAYER IN POOR COUNTRIES CARRY THE BURDEN

If low-income countries were to revise their taxes, strengthen their financial administrations and abolish tax exemptions for transnational investors so that the proportion of public revenues within gross domestic product (which was 12% in 2003) was brought to the average level of the rich countries (26% in 2003), their governments' income would increase by approximately USD 140 billion per year.
The tax income of the developing countries would increase by over USD 285 billion per year if the informal economy could be integrated completely into the formal economy and taxed accordingly. Even if this is unrealistic, partial integration would already bring in many billions in additional income.
