Property owners across the Greater Chennai Corporation (GCC) have been hit with revised property tax demands that are in some cases three to four times higher than what they paid during the first half of 2025-26, prompting widespread concerns over a steep tax hike. The civic body, however, has clarified that there has been no increase in property tax rates, saying the higher demands are the result of correcting under-assessed or incorrectly assessed properties based on discrepancies found through self-declarations, re-measurements, GIS mapping, satellite imagery and other government records, as reported in ANI.
The GCC has around 14 lakh registered property tax assessees across its 15 zones.
The revised demands have triggered complaints from property owners and residents’ associations, particularly over the sharp increase in the amounts payable and the manner in which the reassessments have been implemented, as reported in DT Next.
One such case is that of Radhika Sunder Raj of Anna Nagar, whose property tax reportedly increased from Rs 5,000 in the first half of 2025-26 to Rs 28,000 under the revised assessment.
Is there any official announcement about property taxes being increased? @chennaicorp ???

The GCC has said the revised demands were issued only in cases where discrepancies were found in the assessment of property extent, usage or built-up area and did not represent a general revision of tax rates.
According to GCC officials, the reassessment process was originally initiated following a self-declaration exercise conducted in 2018. Around 1.5 lakh residential property owners had declared deviations in land value assessments during the exercise. Subsequently, discrepancies were identified in around three lakh commercial and non-commercial buildings.
The exercise was kept on hold during the COVID-19 pandemic and has now resumed.
The Corporation has said the latest reassessment combines information furnished by property owners with data obtained through physical re-measurements, Geographic Information System (GIS) mapping, satellite imagery and other government records. The objective is to establish the actual usage and built-up area of properties and correct assessments where discrepancies are found.
The property tax revision exercise was outsourced to a private agency, which conducted a citywide drone-based GIS survey in 2024. The Corporation has been using the survey findings to identify differences between the property details available with the civic body and the actual extent and usage of properties.
Sarbajaya Das, chairperson of the Standing Committee on Taxation and Finance, said the reassessments were being implemented based on discrepancies identified between the GIS survey findings and the property tax payments being made. Commercial properties were taken up first, with reassessments of around 16,000 commercial buildings still under way.
Revised Assessment Effective From Second Half Of 2025-26
The GCC has said it will apply the revised assessment from the second half of the 2025-26 financial year, irrespective of the age of the building or when the deviation occurred, as reported in The New Indian Express.
The Corporation said this approach was intended to reduce the financial burden on property owners by avoiding recovery of revised tax for earlier periods.
The civic body has also invited property owners to challenge revised assessments if they believe the reassessment is incorrect.
Owners can submit objections or grievances, along with supporting documents and evidence, to the concerned Regional Deputy Commissioner within 15 days of receiving the revised assessment order.
The GCC said the objections would be examined by the respective Regional Deputy Commissioners and appropriate action would be taken within one month, or 30 days, of receiving the appeal.
Residents Question Methodology And Lack Of Prior Communication
Residents’ associations have questioned the sharp increases, the retrospective application of the revised assessment and the absence of prior communication to property owners.
Sandhiya Vedullapalli of the Federation of Anna Nagar Residents’ Associations (FOARA) said increases ranging from 10 per cent to more than 300 per cent were unacceptable. She called for the GCC to clarify the methodology used to calculate the revised assessments and justify applying them from the second half of 2025-26.
FOARA also questioned whether taxpayers should be made to bear the consequences of discrepancies arising from earlier administrative assessments.
TK Shanmugam, president of the Federation of North Chennai Residents Welfare Association (FNCRWA), raised concerns over the impact on low-income households and small-scale leather industries in North Chennai.
He also questioned why such an important measure had not been discussed in the Corporation council and pointed to the potential impact of higher property tax assessments on Metro Water tax payments.
Sarbajaya Das said the reassessment exercise would also be extended to domestic properties. She noted that the matter had not been discussed during the finance committee meeting in July and said it would be taken up at the August meeting in view of the revised assessments implemented for the current financial year.
GCC Commissioner GS Sameeran has meanwhile dismissed reports suggesting that the Corporation has increased property tax rates. He said the exercise was intended to ensure accurate assessment and revenue regularisation and was not a blanket increase in property tax.
