IRAS is correcting wrongly granted NSman tax reliefs for ~15,000 taxpayers for YA 2025–26; most adjustments will be small, and automatic refunds/charges handled via assessment notices.

## What Happened
- An error in the Ministry of Defence (MINDEF) system caused **incorrect NSman tax relief** amounts for approximately **15,000 taxpayers** (NSmen, eligible parents, spouses) in Years of Assessment **2025 and 2026**. ([iras.gov.sg](https://www.iras.gov.sg/news-events/newsroom/mindef-iras-clarification-on-correction-of-nsman-tax-relief-records?utm_source=openai))
- MINDEF discovered this in May 2026 and collaborated with IRAS to correct the records.
## Who's Affected & Financial Impact
- Of the 15,000 individuals, about **7,000** will see **increase in tax payable**, **8,000** will get **refunds**.
- Monetary adjustment per individual ranges from under **SGD 10** to about **SGD 900**, with most changes **under SGD 200**.
- Total estimated recovered amounts: **SGD 930,000**; refunds: **SGD 995,000**. ([iras.gov.sg](https://www.iras.gov.sg/news-events/newsroom/mindef-iras-clarification-on-correction-of-nsman-tax-relief-records?utm_source=openai))
## What Individuals Need to Do
1. **Wait for revised Notice of Assessment (NOA)**: IRAS will issue updated NOAs by **September 2026**. Affected taxpayers **do not need to take action** before receiving this.
2. If owing additional tax, check whether you are on a **GIRO instalment plan**; adjustments are automatic. If not, pay by the due date in revised NOA.
3. If qualifying for a refund, that will be processed automatically—no special claim needed.
4. Keep your contact details with IRAS updated so notices and refunds reach you without delay.
## Tips to Avoid Similar Issues
- Regularly **review reliefs claimed** in your NOA when first received.
- If relief involves data from third parties (e.g. MINDEF), check their systems or portals to confirm your activity records.
- Maintain documentation of National Service (NS) activities, related service records, and family ties for relief eligibility.
## Financial Example
Suppose you are an NSman or eligible spouse who mistakenly claimed too much relief: your tax-bill may increase by up to SGD 200, or in some cases nearly **SGD 900** if in higher tax bracket or if multiple dependents were involved. Many, however, will see **minimal changes** (e.g., less than **USD 150** equivalent).
If you already have instalment plan via GIRO, the increase will be folded into upcoming instalments—spreading impact over months.
## Final Thoughts
This correction illustrates how errors in third-party data sources can affect tax reliefs. Though most affected will see small financial changes, the system of automatic rectification and updates to NOAs simplifies resolution. Always check your tax details—even for reliefs—and stay alert for government notifications.
