🇱🇰 TODAY IS THE LAST DAY TO PAY YOUR FINAL INCOME TAX

⭕ September 30 is the deadline to make the final income tax payment for the 2025/2026 Year of Assessment.

⭕ This applies to individuals, companies and partnerships with income tax payable. Any balance remaining after the tax already paid during the year should be settled today.

⭕ If you are an employee, having APIT deducted from your salary does not necessarily mean your full tax obligation is settled.

⭕ Many employees also earn interest from fixed deposits or savings, which counts as investment income. Banks generally deduct 10% Advance Income Tax (AIT) on interest, but depending on your total taxable income, that deduction may not fully cover your final income tax liability.

⭕ Don’t confuse this with the income tax return deadline. The return for 2025/2026 can be filed until November 30, 2026.

⭕ The Inland Revenue Department warns that late payment can result in interest and penalties.

📅 Final tax payment: September 30
📅 Income tax return: November 30

⭕ Not sure how much you need to pay? Use the our Individual Income Tax Calculator to estimate your tax obligation based on your employment, interest and other taxable income.
