Property tax suddenly tripled? Use RTI to challenge it (2026 guide)

This pattern repeats every year in every Indian metro. Property tax revisions due to “Unit Area Value” (UAV) reclassification or revised “ratable value” surveys generate hundreds of thousands of disputes annually. Most citizens just pay, because the corporation's appeal mechanism feels opaque. The RTI surfaces the actual basis — and almost always exposes either a clerical error, a missed exemption, or an ultra-vires demand.

You may have already tried the online portal — MCGM PT app (Mumbai), BBMP portal (Bangalore), GHMC bill enquiry (Hyderabad), NMMC Saral (Navi Mumbai), PMC PT portal (Pune), MCD/NDMC online (Delhi). They show the bill but not the basis. Helplines route you back to the same ward.

• Portal / helpline: Bill amount + payment link. No basis. No officer name. No appeal channel surfaced.
• RTI: PIO (typically the Assessor & Collector of the ward) must give you a written, signed reply in 30 days with the specific UAV/RV calculation, the survey date, the surveyor's name, and the statutory provision invoked. Once you have this, you can file a statutory appeal under the relevant Municipal Act section within the prescribed window (usually 30 days from the demand notice).

The Constitution itself is on your side: Article 265 says no tax shall be levied or collected except by authority of law. The corporation has to show its working — RTI is how you make them.

Property tax is administered by the Property Tax / Assessment Department of your municipal corporation, working through ward offices. The ward office that issued the bill is your starting point.

• Mumbai — MCGM (Brihanmumbai Municipal Corporation), Assessor & Collector, ward office (e.g., A-Ward, K/East)
• Bangalore — BBMP, Joint Commissioner (Revenue), Zonal Office
• Hyderabad — GHMC, Deputy Commissioner (Revenue), Circle Office
• Pune — PMC, Asst. Municipal Commissioner, Ward Office
• Delhi — MCD / NDMC, Assessor & Collector, Zonal Office
• Chennai — Greater Chennai Corporation, Asst. Revenue Officer, Zonal Office

By default, the PIO of the corporation is the Assistant Commissioner / Assessor & Collector of the ward. The First Appellate Authority is one rank above — typically the Deputy Commissioner / Joint Commissioner (Revenue) of the zone, or the Municipal Commissioner for systemic complaints.

Registered Post with AD = tracking + proof. The 30-day clock starts the day the office signs the AD. You may also hand-deliver to the dak counter for a stamped duplicate.

If the appeal window is short (often 30 days from demand) and interest accrues, pay under protest by writing “Paid under protest pending appeal” on the challan. This preserves your right to refund without losing waiver of interest. Mark on the calendar:

• Day 30: RTI reply due.
• Day 31 onwards: §7(2) deemed refusal — file First Appeal immediately.

The First Appellate Authority is typically the Deputy / Joint Commissioner (Revenue) of the zone or the Municipal Commissioner.

Subject: First Appeal under §19(1), RTI Act 2005

I filed an RTI dated [date] (received on [AD date]) at the office of
the PIO, [Ward / Zone]. The 30-day reply window under §7(1) ended on
[day 30]. I have received [no reply / a vague reply not addressing my
numbered questions].

I therefore prefer this First Appeal under §19(1) and request the FAA
to direct the PIO to furnish the information sought and pass orders
under §20 for deemed refusal.

Enclosures: (a) copy of RTI, (b) AD card, (c) PIO reply (if any).

[Signature]

If the FAA fails in 45 days (§19(6)), file a Second Appeal under §19(3) to the State Information Commission.

1. “Tax computation as per [section] of [Act]; UAV Rs _/sq ft, area _ sq ft, factor _, total Rs _.” Verify each line; common errors are area, zone, and usage factor.
2. “Property re-surveyed on [date] by [officer]; reclassified from Zone B to Zone A based on [reason].” If reason is wrong (e.g., your locality is not actually Zone A), file the statutory appeal with the RTI reply.
3. “Notice under §___ issued on [date]; service by registered post.” If you never received it, ask for a copy of the postal AD; absence = bad service = appeal.
4. “Senior-citizen rebate not applied as DOB not on record.” Submit Aadhaar / Form-15H and apply for rebate retrospectively.
5. “Duplicate property entry — to be merged.” Push for merger; refund of duplicate-paid years.

Once you have the reply, file the statutory tax appeal:

• Mumbai (MMC Act 1888): §217 (Investigation Committee) / §406 (suit) — appeal within 21 days of bill.
• BBMP Act 2020: §144 + §149 — appeal to the Assessing Officer / Joint Commissioner within 30 days.
• GHMC Act: §216 — revision petition to the Commissioner within 30 days.
• PMC (BPMC Act 1949): §406 — appeal to the Court of Small Causes / Asst. Commissioner.
• DMC Act 1957 (MCD): §169 — objection within 30 days; appeal to Municipal Taxation Tribunal.

• “Approach the appellate authority directly — RTI not the right route.” RTI is parallel; you need the basis to file the appeal. Khanapuram Gandaiah v. Administrative Officer (2010) 2 SCC 1 confirms RTI does not require justification.
• “Assessment is sub-judice — §8(1)(b).” Routine reassessment is not sub-judice unless an actual case is pending in court. CIC/SS/A/2015/000789 covers this.
• “Personal information of surveying officer — §8(1)(j).” Names of public servants on duty are not personal. Subhash Chandra Agrawal v. CPIO.
• “Information is voluminous — §7(9).” §7(9) only allows the PIO to furnish in a different form, not to deny. Insist on inspection if needed.
• “Internal computation is confidential — §8(1)(d).” UAV / RV calculation is a public formula. Article 265 — no tax without authority of law — overrides.

1. §7(1) — 30 days: PIO replies.
2. §7(2) deemed refusal — Day 31: First Appeal under §19(1) to Dy/Jt Commissioner.
3. §19(6) — 45 days: FAA decides.
4. §19(3) — 90 days from FAA order: Second Appeal to State Information Commission.
5. §20 penalty: Up to Rs 25,000 on the PIO + disciplinary action.

In parallel, the statutory tax appeal continues independently before the Investigation Committee / Asst. Commissioner / Tribunal under the Municipal Act.
