I. STATEMENT OF FACTS

I am the registered owner/authorized representative of the subject property. On [Date Received], I received a Notice of Assessment indicating a significant increase in the assessed value of my property. Upon verification, I noted the following discrepancies between the actual status of the property and the records reflected in your assessment:

  1. Discrepancy in Land Area: The Notice of Assessment indicates a land area of [Incorrect Area in sqm] square meters. However, the Transfer Certificate of Title No. [TCT No.] and the latest Geodetic Survey plan clearly show that the actual land area is [Correct Area in sqm] square meters. The assessment was clearly computed based on an erroneous area.

  2. Discrepancy in Property Classification: The subject property has been re-classified as [Current Classification in Assessment, e.g., Commercial], resulting in a higher assessed value. However, the actual usage of the property remains strictly [Actual Usage, e.g., Residential]. No business activity is being conducted on the premises, and the structure serves solely as a dwelling for my family. This re-classification is factually incorrect and contrary to the definition of property classifications under the Schedule of Market Values of this [City/Municipality].

  3. Excessive Valuation: The assessed value was increased by [Percentage]% without any significant improvement or renovation made to the property. The market value assigned is significantly higher than the zonal valuation and the current market rates of comparable properties in the vicinity.

WHEREFORE, premises considered, it is most respectfully prayed that:

  1. The Formal Letter of Demand and Assessment Notice No. [Number] be CANCELLED and SET ASIDE; or
  2. In the alternative, a reinvestigation be conducted, and a new assessment be issued reflecting the correct tax liability of PHP [Your Correct Tax Computation] , with all surcharges and interest removed.

LIST OF ATTACHED SUPPORTING DOCUMENTS:

I certify that I have not commenced any other action involving the same assessment before any other office or court, and that to the best of my knowledge, no such action is pending. I further undertake to inform this Office immediately should any such action be commenced.

Thank you for your favorable action.

Respectfully submitted,
