I disagree on my tax bill as I have overlooked to claim for business expenses/ reliefs or wrongly declared my income. What should I do?

Please make amendments to your income information and/or tax relief claims through the 'Amend Tax Bill' digital service at myTax Portal. See details in Q4 of Tax Season 2025 – About Your Tax Bill.
