Upon your consent, MINDEF/MHA will retrieve from IRAS the trade income in your Notice of Assessment (NOA) for the year of ORNS activity. If the NOA for the year of ORNS activity is not available, a provisional MUP amount will be auto-generated using your latest available NOA. Any difference will be topped up or recovered from you subsequently when the NOA for the year of ORNS activity becomes available (e.g., NOA 2024 for income earned in 2023).
