A taxpayer can only object to the value that was placed on the property, by the Inland Revenue Department. They cannot object to the tax. If the value is correct, then the tax is correct.
As stated in the Property Section of the website, you have thirty 30 days to object to the valuation of your property, if you believe it has been over or undervalued. After that period, the valuation is permanent until the next valuation period. Once the objection has been received the Department has 45 days to reply to the objection. For more information on how property is valued, look in the Valuation of Property section of the Property Tax tab.
To start the objection process you must complete the Objections Form (OBJ-002 - Objection Form For Property Tax Assessments). In it, you must record your name, address, contact information, the property information and define the reasons under which you are objecting. You may also include any other information that you think is relevant to your case. You should complete the form in its entirety to ensure faster service. The objections letter is sent to the Secretary of the Property Tax Review Board in care of the Inland Revenue Department.
