What is understatement of income to Inland Revenue Department? Why does it happen?
Understatement of income to Inland Revenue Department means failing to declare all taxable income when filing your tax return.
Common situations include:
• Income changes (e.g. job change or unstable income)
• Forgetting to report part-time or additional income
• Submitting tax returns without consolidating all income records
Most of the time, it’s not intentional —
it happens due to job changes, incomplete information, or simple oversight.
💡 Amy’s Tip
If you’ve changed jobs or have multiple income sources, you are more likely to miss something.
Always consolidate all your income records before filing to avoid mistakes.
What are the consequences of Understatement of income to Inland Revenue Department? Will there be penalties?
If understatement of income to Inland Revenue Department is discovered, you may face:
• Recovery of unpaid taxes
• Additional penalties depending on the nature of understatement of income, the degree of the taxpayer’s co-operation and the length of the offence period.
Even if it’s unintentional, you may still be held responsible.
💡 Amy’s Tip
Many people think “it wasn’t intentional” means no problem.
But once understatement of income to Inland Revenue Department occurs,
you may still face consequences, and it could affect your future tax records.
Real Case: Understatement of income to Inland Revenue Department After Job Change
《Case Ref: D17/22》
A physical education teacher working at an international school changed jobs during the tax year (from School A to School B).
When filing taxes, she failed to report income earned from School A.
The Inland Revenue Department later discovered the omission and imposed additional penalties.
The teacher attempted to appeal, but:
• As a teacher, she was presumed to possess a certain degree of literacy
• “Not knowing how to file taxes” was not accepted as a valid excuse
• She should have been aware of the appeal mechanism
In the end, the appeal was rejected, and the teacher had to pay the penalty.
💡 Amy’s Tip
Under tax law, accurate tax reporting is the taxpayer’s responsibility.
Even if the mistake was not intentional, it does not guarantee exemption from penalties.
Simply saying “I didn’t know” is not a valid defense.
Do not rely on common misconceptions.
How to Avoid Tax Filing Mistakes
To avoid understatement of income to Inland Revenue Department:
• Make sure to include all income within the same tax year (previous and current employers)
• Keep complete income records
• Consolidate your income clearly before filing
This is especially important in years when you change jobs.
