Real Property Tax (RPT) in the Philippines is governed by the Local Government Code of 1991 (Republic Act No. 7160). Local government units (LGUs) assess the value of real properties to determine the tax due. However, there are instances where property owners believe the assessment is excessive, unfair, or based on incorrect property details (e.g., wrong land area, incorrect classification).
Under Section 226 of the Local Government Code, a property owner has the right to contest an assessment. This report outlines the procedure and provides a comprehensive sample letter.

Dear Sir/Madam,
Re: Protest on Tax Assessment for the Year [Year] On [Date], we received Formal Letter of Demand/Assessment
I/We, [Your Name], with TIN [Your TIN], respectfully submit this letter as a formal protest to the tax assessment notice received on [Date Received], for the taxable year [Taxable Year].
The said assessment pertains to an alleged underpayment of [Tax Type] amounting to PHP [Amount]. I/We strongly disagree with the findings and computations in the assessment.
Grounds for Protest:
Error in Computation: The assessment incorrectly computed my taxable income, overlooking allowable deductions and exemptions.
Incorrect Tax Classification: My business operations qualify for a different tax classification that significantly reduces my tax liability.
Supporting Documents:
Relief Sought:
I/We respectfully request a re-evaluation of the tax assessment and a reduction/cancellation of the alleged tax liability, taking into account the allowable deductions and correct tax classification.
Conclusion:
I/We are confident that upon review of the facts and supporting documents, the assessment can be revised accordingly. I/We look forward to a prompt and fair resolution of this matter.

[List attached documents]
Thank you for your attention to this matter.

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:
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.
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].
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.

RE: PROTEST / REQUEST FOR RECONSIDERATION Subject: Formal Letter of Demand No. [FLD Number] dated [Date of FLD] Taxable Year: January 1, [Year] to December 31, [Year] Tax Type: Deficiency Income Tax / Value-Added Tax / [Specify] Amount Assessed: Php [Total, e.g., 1,250,000.00]
Dear Revenue District Officer:
I, JOHN A. DELA CRUZ, of legal age, Filipino, married/single, with TIN [Number], and registered business address as indicated above, under oath, state that:
On [Date you received the FLD], I received a Formal Letter of Demand (FLD) No. [Number] dated [Date of FLD], together with the details of discrepancy and assessment notices, alleging deficiency [Type of Tax] for the taxable period ending December 31, [Year], in the total amount of Php [Amount].
I respectfily PROTEST the aforesaid assessment, as I find it to be erroneous, invalid, and/or unsupported by evidence.
The specific legal and factual grounds for this protest are as follows:
a) Unsubstantiated Disallowance of Deductions. The BIR disallowed documented operating expenses in the total amount of Php [Amount] for [Reason, e.g., advertising and promotion]. The corresponding official receipts and invoices were presented during the audit, which are valid and duly issued by registered suppliers.
b) Mathematical Error in Tax Computation. The assessment incorrectly computed the net taxable income by failing to consider the approved carry-over of excess Minimum Corporate Income Tax (MCIT) from prior year.
c) Violation of Due Process. The BIR failed to issue a Preliminary Assessment Notice (PAN) prior to the issuance of the FLD, which is a mandatory requirement under Section 228 of the NIRC of 1997, as amended. Consequently, I was deprived of the opportunity to respond to the initial findings.
I am attaching herewith the following supporting documents as required under Revenue Regulations No. 12-99, and I shall submit additional documentary evidence within the 60-day period prescribed by law:
WHEREFORE, premises considered, it is most respectfully prayed that the Formal Letter of Demand No. [Number] be CANCELLED and WITHDRAWN, and that no deficiency tax be assessed for the said taxable period.
Other reliefs just and equitable under the law are likewise prayed for.

Once the protest is filed, the BIR must act within strict deadlines:
| Step | Action | Deadline | |------|--------|----------| | 1 | Filing of valid protest | Within 30 days from receipt of FLD/FAN | | 2 | Submission of supporting documents | Within 60 days from filing of protest (may be extended for justifiable reason) | | 3 | BIR decision on protest (final decision) | Within 180 days from date of submission of documents | | 4 | Appeal to Court of Tax Appeals (CTA) | Within 30 days from receipt of BIR’s final decision |
Important: If the BIR fails to decide within 180 days, the taxpayer may appeal to the CTA within 30 days after the expiry of the 180-day period (doctrine of inaction). Failure to appeal results in the assessment becoming final.
