Module C: Formula & Methodology Behind the Calculation

Tambaram Municipality uses a modified version of the Annual Rental Value (ARV) system with zone-based multipliers. The 2024-25 calculation follows this precise formula:

1. Base Rate Determination

The base rate per sq.ft is determined by:

Base Rate = Zone Multiplier × Construction Factor × Age Factor × Occupancy Factor

Zone Multipliers (2024-25)

Zone	Residential Rate (₹/sq.ft)	Commercial Rate (₹/sq.ft)	Industrial Rate (₹/sq.ft)
A	₹12.50	₹25.00	₹18.75
B	₹8.75	₹17.50	₹13.12
C	₹5.00	₹10.00	₹7.50
D	₹2.50	₹5.00	₹3.75

2. Construction Type Factors

Construction Type	Factor	Description
RCC	1.0	Standard multiplier
Brick & Mortar	0.85	15% reduction
Steel Structure	1.1	10% premium
Wooden Structure	0.7	30% reduction

3. Age Adjustment Factors

Properties receive age-based adjustments:

• 0-5 years: 1.0 (full rate)
• 6-15 years: 0.95 (5% reduction)
• 16-30 years: 0.90 (10% reduction)
• 31+ years: 0.85 (15% reduction)

4. Occupancy Status Impact

Different occupancy types affect calculation:

• Self-Occupied: Taxed at 60% of ARV
• Rented: Taxed at 100% of actual rent or ARV (whichever is higher)
• Vacant: Taxed at 50% of ARV (maximum 2 years)

5. Final Calculation Formula

Annual Property Tax = (Plinth Area × Base Rate × Occupancy Factor) + (10% Library Cess) + (2% Education Cess)

Where:
- Base Rate = Zone Rate × Construction Factor × Age Factor
- Occupancy Factor = 0.6 (self), 1.0 (rented), or 0.5 (vacant)

6. Payment Structure

Tambaram Municipality collects property tax in two half-yearly installments:

• First Half: April 1 to September 30 (Due by April 30)
• Second Half: October 1 to March 31 (Due by October 31)

Late payments incur 2% monthly interest on the outstanding amount.

Calculation:

1. Base Rate = ₹8.75 (Zone B) × 1.0 (RCC) × 0.95 (age 6-15) = ₹8.31/sq.ft
2. Annual Value = 1,500 × ₹8.31 = ₹12,465

2. Annual Value = 2,200 × ₹25.00 = ₹55,000
3. Rent Comparison: ARV (₹55,000) vs Actual Rent (₹6,00,000) → Higher value used

2. Annual Value = 900 × ₹3.61 = ₹3,249
3. Occupancy Adjustment = ₹3,249 × 0.6 = ₹1,949.40

How is property tax calculated for apartments in Tambaram?

Apartments in Tambaram have a specialized calculation method:

1. Undivided Share (UDS) Basis:

• Each flat’s tax is calculated based on its UDS of the total land
• UDS is mentioned in your sale deed (e.g., 0.5% of 2 acres)
• Common areas are proportionally divided among all units

2. Calculation Formula:

Apartment Tax = (UDS × Land Rate) + (Built-up Area × Zone Rate × Construction Factor)

Where:
- Land Rate = ₹500/sq.ft (Zone A), ₹300/sq.ft (Zone B), ₹150/sq.ft (Zone C)
- Zone Rate = Standard residential rates
- Construction Factor = 1.0 for RCC (most apartments)

3. Special Considerations:

• Stilt Parking: 30% of covered parking area is taxable
• Common Amenities: Swimming pools, gyms add 5% to total tax
• Lifts: ₹2,000/year per lift, divided among all units
• Generator Rooms: 20% of their area is taxable

4. Example Calculation:

For a 1,200 sq.ft flat in Zone B with 0.4% UDS in 1-acre plot:

• Land Component = (0.4% of 43,560 sq.ft) × ₹300 = ₹5,227
• Building Component = 1,200 × ₹8.75 × 1.0 = ₹10,500
• Total Before Cesses = ₹15,727
• With Cesses = ₹15,727 × 1.12 = ₹17,614

Note: Gated communities with >50 units may qualify for bulk assessment discounts (contact the municipality).
