A system error at MINDEF has resulted in incorrect NSman tax relief amounts for about 15,000 taxpayers. The error affects these taxpayers in different ways, with some facing a higher tax bill and others seeing a decrease. Approximately 7,000 taxpayers will have to pay more, while around 8,000 will pay less.

The discrepancy is due to the system error, but further details are not provided here. For more information, readers can refer to the original source.

The error's impact is uneven, with a slightly larger number of taxpayers seeing a decrease in their tax bill than an increase.
