MINDEF–IRAS NSman Tax-Relief Record Correction (September 2026)

On 3 September 2026, MINDEF and IRAS said that incorrect National Service activity records had produced incorrect NSman tax-relief amounts for approximately 15,000 taxpayers across Income Tax Years of Assessment (YA) 2025 and 2026. The affected population included NSmen as well as eligible parents and spouses; the issue was an administrative-record error, not a change to the NSman-relief scheme itself (MINDEF, 3 September 2026).

Direction and size of the adjustments

Of the approximately 15,000 affected taxpayers, MINDEF and IRAS estimated that about 7,000 would see an increase in their tax bill and about 8,000 a decrease. The authorities said about S$930,000 would be recovered and about S$995,000 refunded in total. Most adjustments were expected to be below S$200, but the reported range could run from under S$10 to about S$900 depending on the taxpayer's relief entitlement and income-tax bracket (MINDEF, 3 September 2026). These are correction totals for the identified YA 2025–2026 records, not a new tax rate or a general NSman-relief amount.

Rectification and taxpayer action

MINDEF said it identified the inaccuracies in May 2026 while reviewing NSmen’s queries and checking records, and has rectified the underlying errors. Affected NSmen were directly notified. IRAS said revised Notices of Assessment would be issued by September 2026, showing any additional tax payable or refund; taxpayers do not need to act before receiving a revised notice. GIRO instalment plans will be adjusted automatically where applicable, while taxpayers not on GIRO should follow the payment due date on the revised notice and refunds will be made automatically (MINDEF, 3 September 2026).

Relationship to the standing NSman-relief rules

IRAS normally grants NSman Self Relief automatically using eligibility and activity records supplied by MINDEF, SPF and SCDF. For YA 2026, the relevant NS activity work year is 1 April 2025 to 31 March 2026; the ordinary relief quantum depends on whether qualifying NS activities were performed and whether the person holds a key command or staff appointment (IRAS, NSman Relief, accessed 3 September 2026). The September correction therefore concerns the accuracy of records used in particular assessments, not an across-the-board revision of every NSman’s relief entitlement.
