Taxpayers reminded of September 30 deadline for final 2025/2026 tax payment

The Inland Revenue Department (IRD) has reminded all taxpayers of the approaching September 30 deadline for submitting final tax payments for the 2025/2026 Year of Assessment. The notice emphasizes the importance of meeting this critical date to avoid potential penalties and compliance issues.

Taxpayers are advised to ensure all outstanding tax liabilities are cleared by the stipulated deadline. The IRD has encouraged individuals and businesses to verify their tax records and make necessary adjustments to avoid last-minute complications.

Failure to comply with the deadline may result in additional charges, interest, and other enforcement actions by the revenue authority. The department has urged taxpayers to seek assistance from their tax advisors or contact the IRD directly if they require clarification on their tax obligations.

The final payment deadline is part of the IRD's regular tax administration calendar and applies to all categories of taxpayers, including individuals, corporations, and self-employed professionals. Those who have already settled their taxes in installments should verify that all payments have been properly credited.
