In view of the complexity of the provisions relating to the tax on individuals, we have included as Exhibit E an example to illustrate the computation of the tax. 49. Payment of the tax: Individuals who receive combined income in cash or in kind in excess of US$6,000 in the months of January to June from personal services and from capital investments, taken together, or those who receive such amount of income solely from capital investments, are obligated to make a provisional payment in the month of August which is calculated by applying the tax table of Exhibit D; from the provisional payments so determined the taxes withheld or paid for purposes of the taxes on income from personal services and on capital investments can be deducted. In the month of April, individuals subject to this tax must file a return covering their combined income, to which the rates of Exhibit D are applicable. From the resulting tax are deducted taxes paid on personal services and/or on income from invested capital, which relate to the combined income. Also obligated to file an annual tax return are those taxpayers who have made the provisional payment, even though by year-end-they are not subject to this tax.
