Step 7: Review Information

Review all the income and deduction information you’ve entered. The system will automatically calculate the tax amount due. If you have already paid tax, the system will notify you of any overpaid tax, which you can request a refund for, or allocate it to support political parties. After reviewing all the information, click "Next."

Step 8: Confirm Submission

Once all the information is reviewed, click "Confirm Submission" to complete the online individual income tax filing process.

If you’re preparing to file your taxes, it’s recommended to do so online as early as possible.
