The 1979-80 budget in Mauritius was highly anticipated as the country faced a crushing tax burden, particularly in the 1970s. The Mauritius Tax Payers' Association had made several representations and proposals prior to the budget presentation, calling for a major review of the income tax system. However, the budget did not provide the expected relief, instead announcing additional indirect taxes that had a direct impact on inflation. This led to widespread discontent among taxpayers, the private sector, and consumers.
In response to the outcry, the Mauritius Tax Payers' Association called for protests and rejection of the budget. Protracted discussions between the Association and the Ministry of Finance ensued, resulting in several income tax changes incorporated into the budget. The personal deduction was raised from Rs 4,500 to Rs 5,500, a 22% increase, the largest in the 1970s. Additionally, the limit on a few other deductions was adjusted upward.
A significant development in the 1979-80 budget was the introduction of separate taxation for a working wife, at the option of the taxpayer. This marked a major victory for women's rights, as previously a wife's income was cumulated with her husband's, resulting in a higher marginal tax rate. This change brought Mauritius in line with the UK, which had allowed separate taxation since 1972-73. Furthermore, an earned income relief of 5% was introduced on earned income, subject to a maximum of Rs 5,000.
The 1979-80 budget also modified the tax brackets and rates. The first slab of taxable income of Rs 10,000 was divided into two, with a new marginal tax rate of 5% on the first income range and 10% on the second range. These changes benefited all taxpayers, small and large, and marked a fundamental shift in the development of Mauritius' income tax system.
The impact of the tax concessions was a 13% drop in income tax revenue between 1978-79 and 1979-80. However, most deductions were subject to a ceiling, ensuring that taxpayers contributed a fair share of expenses. The deductions were designed to prevent abuse and overstatement of actual expenses, while fulfilling specific needs such as encouraging savings and investment in housing.
An analysis of effective tax rates between 1978-79 and 1979-80 shows that the average effective tax rate fell from 14.7% to 12%, a decline of almost 20%. The impact was favorable on all income groups, with lower income groups experiencing a more substantial decline in effective tax rates. However, the tax burden remained high for high-income earners, with marginal tax rates ranging from 5% to 75%.
The 1979-80 budget marked a turning point in Mauritius' income tax reform, recognizing the need for an annual review of tax policies. The changes introduced in the budget had a lasting impact, with piecemeal changes continuing to be made in the following years. The budget's focus on providing relief to taxpayers and promoting a more progressive tax structure set a precedent for future budgets.
