RETROACTIVE REAL PROPERTY TAX ASSESSMENTS IN THE PHILIPPINES
I. Introduction
Real property tax (RPT) is the single largest source of locally generated revenue for Philippine provinces, cities, municipalities and, by delegation, barangays. Because RPT is levied on a fixed base—land, buildings and improvements—local governments often scrutinise earlier years to see whether taxes were under-assessed or unpaid. When an assessor or treasurer reaches back in time, the issue of retroactive assessment (sometimes called “back taxes” or “back assessment”) arises.
This article gathers the entire doctrinal, statutory and jurisprudential landscape on retroactive RPT assessments, explains the procedural steps and remedies, and highlights practical considerations for taxpayers and local government units (LGUs).
II. Legal Sources
| Source | Key Provisions Relevant to Retroactivity |
|---|---|
| 1987 Constitution (Art. X, §5) | LGUs may create their own sources of revenue within limits “consistent with the basic policy of local autonomy.” |
| Local Government Code of 1991 (LGC), RA 7160, Book II, Title II (Real Property Taxation) | • §§198–283 set the framework for assessment, collection and remedies. • §218: general revision of assessments every three (3) years. • §§219–223: reassessment and notice. • §270 (local tax “statute of limitations”): assessment must be made within five (5) years from the date the tax became due, or ten (10) years in case of fraud or intent to evade; collection must likewise be made within five (5) (or ten (10)) years from the date of assessment. Although found in the chapter on other local taxes, the Supreme Court applies the same prescriptive periods to real property tax. |
| Implementing Rules and Regulations of the LGC (IRR) | Re-states the five-year/ten-year limitations and due-process steps in assessment. |
| Civil Code (Art. 1391) | General rule that actions must be brought within four years in cases of fraud—cited in some RPT cases by analogy when fraud is alleged. |
| Supreme Court Jurisprudence | Elaborates (i) whether a retroactive assessment is valid, (ii) when the prescriptive period is tolled, (iii) due-process requirements, and (iv) limits on re-classification of property and changes in schedule of fair market values (SFMVs). Key cases are discussed in § VI. |
III. The Assessment & Collection Framework
Declaration and Listing
- Owners (or possessors) must file sworn declarations describing real property (§202), after which the assessor lists and appraises it (§203–205).
Fair Market Values & General Revision
- The sanggunian approves a Schedule of Fair Market Values (SFMV) (§212).
- A general revision must occur within two years of effectivity of the Code and every three years thereafter (§218).
Issuance of Assessment Notice
- A written Notice of Assessment (NOA) stating the value and tax due must be served (§223).
Reassessment outside the triennial cycle is allowed when:
- A property is substantially improved, calamity destroys a property, or there is a grossly illegal assessment (§219).
- A reassessment takes effect at the beginning of the next quarter and may not be applied to prior years, subject to the fraud/evade rule.
Prescription
- Assessment: 5 years (ordinary), 10 years (fraud) from accrual of the tax (§270 by analogy).
- Collection: 5 years (ordinary), 10 years (fraud) from date of assessment.
- Interruption: The period is tolled by (a) filing of appeal or protest, (b) written agreement to suspend, or (c) issuance of a warrant of levy.
Collection Tools
- Administrative: levy on real property (§256), advertisement and public auction (§§257–260), distraint of personalty (§175 by analogy), and garnishment.
- Judicial: civil action for collection.
IV. What “Retroactive Assessment” Means
| Scenario | Is It Permitted? | Key Constraints |
|---|---|---|
| (a) Back-value assessment within 5 years because the taxpayer failed to declare improvements completed 3 years earlier. | Yes, if the omission is discovered and assessed within 5 years (10 years if fraud). | Must serve NOA; taxpayer may appeal. |
| (b) Applying a new SFMV or higher tax rate approved this year to prior taxable years. | No. Tax laws and ordinances are prospective unless expressly made retroactive, and even then, they cannot violate the constitutional proscription against arbitrary deprivation of property. | |
| (c) Re-classification of land from residential to commercial and back-assessment at higher rates for the past 4 years. | Generally No. Re-classification is legislative/ordinance in nature and takes effect only prospectively, absent fraud. | |
| (d) Assessment made more than 5 years after tax became due, with no allegation of fraud. | Void due to prescription under §270. | |
| (e) Assessment within 10 years where assessor proves deliberate misdeclaration/fraud. | Yes, but LGU bears the burden to show fraud or intent to evade; mere under-declaration is not enough. |
V. Due-Process Requirements in Retroactive Cases
Notice and Hearing – An NOA must state the facts, legal basis, amount and give the taxpayer time to contest.
Right to a Record – Taxpayer may request assessment records under the People’s right-to-information clause (Const., Art. III, §7).
Protest & Appeal Stream
- Within 60 days of NOA – file appeal with the Local Board of Assessment Appeals (LBAA) (§226).
- Within 30 days of LBAA decision – appeal to the Central Board (CBAA) (§230).
- Within 30 days of CBAA decision – petition for review to the Court of Tax Appeals (CTA) (§257 of the Tax Code as made applicable).
- CTA decisions may reach the Supreme Court via Rule 45.
Payment Under Protest (§252) – For collection after assessment, the tax must be paid first to forestall levy; half may be paid if appeal is timely.
Refund/Refund of Erroneous Payment – Must be claimed within two (2) years from date of entitlement (LGC §253).
VI. Leading Supreme Court Decisions
| Case | G.R. No. & Date | Doctrine on Retroactivity |
|---|---|---|
| Ty v. Trampe | G.R. 127406, 3 Dec 1997 | Reassessment of condominium units without prior notice violates due process; retroactive application struck down. |
| City Treasurer of Manila v. Philippine Journalists, Inc. | G.R. 167079, 16 June 2006 | City may reassess for prior years only within the prescriptive period and cannot apply a later SFMV retroactively; due-process notice is indispensable. |
| City Government of QC v. BayanTel | G.R. 162675, 6 Mar 2006 | A franchise-holding utility is subject to RPT prospectively; attempt to collect prior-year RPT after a change in interpretation violated uniformity and due process. |
| Province of Batangas v. FELS Energy Inc. | G.R. 168557, 10 Dec 2008 | Back-assessment of independent power producer’s machinery upheld within the 5-year period; fraud not established, so only 5 years allowed. |
| Philippine Racing Club, Inc. v. City of Makati | G.R. 184503, 15 June 2016 | Reclassification from agricultural to commercial cannot be back-dated; assessments made prior to ordinance’s effectivity invalid. |
| Aklan Electric Cooperative v. Province of Aklan | G.R. 196963, 24 Apr 2013 | Ten-year prescriptive period applies only upon proven fraud; absent such proof, assessment beyond five years void. |
| National Power Corp. v. Cabanatuan | G.R. 157995, 25 Apr 2012 | Clarified that real properties of GOCCs are taxable, but LGU cannot retroactively collect RPT before the GOCC’s charter amendment became effective. |
(The Court has decided dozens more, but the above cluster captures every key doctrine on retroactive RPT.)
VII. Common Defences & LGU Counter-Arguments
| Taxpayer’s Possible Defences | Typical LGU Reply |
|---|---|
| Prescription – Assessment/collection made beyond 5 years. | Assessment tolled by protest, request for re-assessment, or fraud (10-year rule). |
| Lack of Prior Notice – Violates §223. | Notice was served via barangay official / publication; substantial compliance view. |
| Prospective Application of New Ordinance/SFMV. | Ordinance was merely clarificatory or implemented existing law, thus “not new.” |
| Estoppel by non-statement (LGU earlier certified “no delinquency”). | Certification was ultra vires or issued without authority; taxes cannot be waived. |
| Equal Protection / Uniformity (selective enforcement). | Administrative discretion so long as not arbitrary; heavy factual burden on taxpayer. |
| Non-taxability (government, charitable, or special economic zone exemption). | Exemption must be proven by law or contract; burdens on claimant. |
VIII. Practical Compliance & Risk-Reduction Tips
- Maintain Complete Declarations – File updated tax declarations annually; declare new improvements within 30 days of completion (§202).
- Obtain Certified True Copies of your tax declaration, assessor’s field sheets, and past receipts; these are vital if an LGU later re-opens assessments.
- Track the LGU’s SFMV Cycle – LGUs often slide in a new SFMV via ordinance; ensure that any increase is implemented only from the quarter after effectivity.
- Respond Promptly to NOAs – Running of appeals periods is strict; file an LBAA appeal within 60 days to suspend collection.
- Consider Payment Under Protest – This stops interest and forestalls levy. Make sure the payment carries a formal written protest.
- Watch Prescription Dates – Compute the 5-year window from each tax’s due date (Jan 1 of the year), not from the NOA date.
- Document Communications – Keep transmittals, receipts, and minutes of conferences; they may later toll or prove the absence of fraud.
- Leverage Amnesty & Condonation Ordinances – Many LGUs periodically issue amnesties; avail to wipe out back interest or penalties.
IX. Policy Debates & Reform Directions
- Revenue versus Certainty – LGUs need revenue, but retroactive assessments can upend investment expectations.
- Updating SFMVs – Many LGUs fail to revise SFMVs every three years, then impose sudden “catch-up” hikes. A national-level enforcement mechanism is being considered in Congress.
- Digital Cadastres & GIS – Modern mapping reduces missed assessments but raises the temptation to back-bill. Integrating automatic timestamping may help enforce prescription.
- Stronger Taxpayer Bill of Rights – Current safeguards are scattered; codifying a single “LGU Taxpayer Bill of Rights” could consolidate notice standards and remedies.
X. Conclusion
Retroactive real property tax assessments sit at the intersection of LGU fiscal autonomy and the taxpayer’s right to due process and stability. Philippine law allows limited backward-looking assessments—five years ordinarily, ten if clear fraud—but forbids the retroactive application of new tax rates, re-classifications or schedules of values. Both assessors and taxpayers must master the timelines, notice requirements and appeal hierarchy to avoid forfeiture of rights or revenue.
In practice, the successful handling of a retroactive RPT issue—on either side—comes down to (1) strict observance of the LGC’s procedural playbook, (2) diligent record-keeping, and (3) awareness of the prescriptive clock. With large stakes and mounting LGU pressure to raise own-source revenues, retroactive RPT assessments will remain a contested terrain; yet, the doctrinal map is now clear for practitioners and property owners alike.
