The high levels of crime in South Africa are a popular topic of conversation amongst South Africans. As a result of the high levels of crime in South Africa, many South Africans employ private security companies in order to protect themselves and their property. The opinion exists that these private security costs should be allowed as a deduction against their taxable income. The study investigates certain factors that may influence crime, the private security industry and these companies’ perception on the duties of the South African Police Service. In order to determine private security companies’ perception on the duties of the South African Police Service, a questionnaire was conducted. The results reflected not only that private security companies are more effective and proactive in the prevention of crime, but also that they have a faster reaction time to emergency calls than the South African Police Service. This can lead one to argue that it has become a necessity to incur private security costs in South Africa. It also discusses current South African tax legislation in comparison with international trends. The study concludes whether the deduction of private security costs for the individual against taxable income is allowed in South Africa.
