The New Delhi Municipal Council’s proposed shift to the unit area method could fundamentally change how property tax is calculated across one of the capital’s most closely administered urban areas. The draft combines a 30% rebate for eligible self-occupied homes with a formula based on use, age, structure, occupancy, location and infrastructure, but the system will not take effect until public feedback, council approval, parliamentary ratification and a further valuation process are completed.
That sequence is important because the draft does not yet establish the final tax rates or the amount payable by individual properties. Instead, it proposes the framework through which those rates would later be determined. The reform therefore represents less an immediate tax cut than a change in the administrative logic of property taxation in the NDMC area.
The council currently uses the rateable value method, which is based on the assessed value of a property. The Municipal Corporation of Delhi, by contrast, follows the unit area method, which calculates tax through a formula using factors such as property size, use and age. According to the report, residents in the NDMC area have been demanding a shift to the unit area method since 2016. Traders in locations including Khan Market and Connaught Place continue to pay property tax under the existing rateable value system.
The proposed change matters because the two methods organise information about a property differently. Under the draft, the tax calculation would take account of the property’s use, whether residential, commercial, office, hotel, hospital, nursing home, recreational or industrial. It would also consider whether the structure was built before or after 1960, whether it is classified as kuccha or puccha, whether it is self-occupied or rented, and the circle-rate category of its location.
Infrastructure and location would form another part of the formula. The width of the road or street adjoining a property would be divided into three categories: 24 metres and above, between 13.5 metres and 24 metres, and below 13.5 metres. The draft also refers to the infrastructure available in an area. These provisions indicate an attempt to connect the tax assessment more closely to the physical and locational characteristics of the urban environment, rather than relying only on an assessed property value.
Yet the framework also creates a significant implementation question: the same building type may produce different liabilities depending on its use, age, location, road width and occupancy. The proposal does not, in the material supplied, specify the final base unit area values or tax slabs. Those will be recommended later by a municipal valuation committee. Until that committee makes its recommendations and they are approved, taxpayers cannot establish the complete financial effect of the proposed method.
The draft proposes a 30% rebate for self-occupied residential properties belonging to men aged 65 and above, all women and persons with disabilities. The concession would apply only to plots with a built-up area of up to 100 square metres and would be available for no more than one residential building within the NDMC jurisdiction. The eligibility conditions make the proposal targeted rather than universal: the benefit depends on the owner’s category, the use of the property, its built-up area and the number of buildings covered.
A separate rebate of up to 15% is proposed for taxpayers who pay the entire property-tax amount by June 30 of the financial year. The draft also allows payment either as a lump sum or in four equal quarterly instalments. For delayed payments, it proposes simple interest of 1.5% per month or part thereof. These provisions link the proposed assessment system to collection behaviour, offering an incentive for early payment while increasing the cost of delay.
The proposal also addresses plots that are not substantially built upon. The draft would apply the standard tax rate where construction covers 25% of a plot’s area. If construction covers less than that threshold, an additional charge called vacant land tax may be imposed at a rate to be determined by NDMC. This provision could become significant for properties where the value of the land is high but the built-up area is limited, although the supplied material does not establish the proposed vacant-land rate or its eventual distribution across property categories.
Another administrative provision concerns buildings or vacant land occupied by multiple parties. The draft proposes a processing fee of Rs 100 per assessee for each assessment period when information is requested on the apportionment of property tax among multiple occupants, including for previous assessment periods. The fee reflects a move towards formalising the information required to divide tax liabilities, but the draft’s practical effect will depend on how NDMC records occupancy and resolves disagreements among occupants.
The reform is being presented by NDMC as part of the Jan Vishwas Act (Amendment of Provisions), 2026, and as an effort to simplify the property-tax system. An official quoted in the report said the changes would reduce disputes, improve transparency and create greater predictability in tax liabilities. The official also described the existing system as a pre-Independence-era “property tax inspector raj”. That characterisation is an official assessment of the current process, not an independent finding established in the supplied material.
The next stage is public scrutiny. NDMC has invited suggestions on the draft until October 23. After examining the feedback, the council will place the proposal before itself for approval and incorporate suggestions where required, according to the agency. A formal notification would then be issued and submitted to Parliament for ratification. The proposal is therefore not yet an enforceable replacement for the current rateable value method.
If the reform receives the required approvals, a municipal valuation committee will recommend the tax rates, slabs, base values and categorisation of colonies within the NDMC area. The base unit area values for each category would remain in force for three years. Those values would then be multiplied by five factors: use, age, structure, occupancy, and infrastructure and location. The committee’s recommendations would subsequently return to the council for approval and implementation.
This structure places the most consequential decisions after the initial policy announcement. The draft establishes the categories and factors, but the valuation committee will determine the numbers that turn those categories into tax demands. That means the public feedback process will be relevant not only to the principle of adopting the unit area method, but also to how properties are classified and how the eventual rates are calibrated.
The proposed NDMC property tax reform consequently raises a broader urban-governance question: can a rule-based formula make municipal taxation more predictable without overlooking the differences between old buildings, mixed-use properties, high-value commercial districts and lightly developed plots? The draft attempts to answer that through a larger set of measurable factors. Its final effect, however, will become clear only when the valuation categories, base values and rates are published.
For residents and property occupiers, the immediate development is the opportunity to respond to the draft before approval. For NDMC, the central administrative task will be to translate the proposed framework into consistent assessments and a transparent valuation process. The next milestones are the October 23 deadline for public suggestions, consideration by the council, parliamentary ratification and the later recommendations of the municipal valuation committee.
