Stamp Duty and Registration are essential parts of every real-estate transaction in Maharashtra. However, the calculation method varies depending on the property type, age, location, floor level, kind of transaction, and relationship between parties.
This guide explains the current rules and shows you exactly how to calculate Stamp Duty for flats, shops, car parking spaces, terraces, lofts, and more.
1. Current Stamp Duty & Registration Charges in Navi Mumbai
For a straightforward purchase of a new or resale flat, Stamp Duty is charged at the flat rate announced periodically by the Government of Maharashtra.
Current Rates (2025)
- Stamp Duty (Navi Mumbai): 5%
- Registration Charges: 1%, capped at ₹30,000
- Women Homebuyers Discount: 1% less on Stamp Duty
- Additional Municipal Cess / LBT: Usually 1%, depending on the jurisdiction
- Extra surcharges may apply in certain areas, sometimes raising the total by up to 2%
Key point:
Although a flat can be sold at any mutually agreed price, Stamp Duty is always calculated on the Ready Reckoner Value or the Agreement Value, whichever is higher.
2. How Ready Reckoner Rates Affect Stamp Duty
Before calculating Stamp Duty, you must check the Ready Reckoner Rate for the exact location of the property.
To find the correct rate:
- Select your district
- Select your location based on Sector No., Plot No., TPS No., etc.
- Identify the property type (Flat, Shop, Office, Plot)
- Note the rate per sq. meter of built-up area
Once you have the rate, use this formula:
Built-up Area (sq.m.) × Ready Reckoner Rate = Government Valuation
Stamp Duty is applied on this valuation.
3. Converting Carpet Area to Built-Up Area
Most buyers know only the Carpet Area, but Ready Reckoner values are based on Built-Up Area.
Conversion formulas
- Carpet → Built-up
Built-up Area = Carpet Area × 1.1 - Built-up → Carpet
Carpet Area = Built-up / 1.1
This conversion is mandatory before calculating Stamp Duty.
4. Stamp Duty on Balconies, Terraces, Lofts & Basements
Not all areas are counted equally. Different components of the property attract different percentages.
Area Consideration for Stamp Duty
| Component | % of Area Counted |
|---|---|
| Enclosed Balconies | 100% |
| Open Balconies | 40% |
| Terrace Above Flat (internal access) | 25% |
| Terrace Above Shop/Office | 40% |
| Loft (Commercial) | 50% |
| Loft (Residential) | 25% |
| Basement (godown use) | 70% |
These percentages must be applied before multiplying the area with the Ready Reckoner Rate.
5. Stamp Duty on Car Parking
Parking spaces also carry valuation based on their type.
Parking Area Consideration
| Parking Type | % of Area Counted |
|---|---|
| Open Parking | 40% |
| Covered / Stilt Parking | 25% |
Example:
1 open car parking = approx. 6.97 sq.m (70 sq.ft.)
Stamp Duty applicable area = 40% of 6.97 = 2.78 sq.m
6. Floor-Wise Increase or Decrease in Value
The value of a flat may increase or decrease depending on:
- Whether the building has a lift, and
- Which floor the property is on
A. Without Lift – Value Decreases with Height
| Floor | Value Considered |
|---|---|
| Ground | 100% |
| 1st / Stilt | 95% |
| 2nd | 90% |
| 3rd | 85% |
| 4th & Above | 80% |
B. With Lift – Value Increases Above 4 Floors
| Floor | Increased Valuation |
|---|---|
| Ground to 4th | No increase |
| 5th to 10th | +5% |
| 11th to 20th | +7.5% |
| 21st & Above | +10% |
7. Depreciation Allowed for Older Buildings
Depreciation applies only in:
- Ready Reckoner valuation cases
- Gift deeds
Depreciation Rates (RCC Structures)
| Age of Building | Depreciation |
|---|---|
| 0–2 years | 0% |
| 2–5 years | 5% |
| 5+ years | 1% per year (up to 70% max) |
Older buildings can therefore attract lower Stamp Duty values.
8. Stamp Duty on Gift Deeds (Very Important Rule)
Discounted Stamp Duty applies only to transfers between blood relatives.
Gift Deed Rates (2025)
| Relationship | Stamp Duty | Registration |
|---|---|---|
| Parent → Son/Daughter | 2% + ₹200 | ₹200 |
| Son/Daughter → Parent | 4% | 1% (max ₹30,000) |
This is a common area of confusion for many buyers.
9. Putting It All Together — Final Calculation Steps
To calculate Stamp Duty:
- Convert the area to built-up sq.m.
- Adjust the area (balcony/terrace/loft/% rules)
- Apply Ready Reckoner Rate
- Apply floor-wise increase/decrease
- Apply depreciation (if applicable)
- Compare with agreement value
- Pay Stamp Duty on the higher of the two values
10. Final Notes & Resources
Stamp Duty calculation can get complicated when:
- The property includes multiple components (open terrace + loft + parking)
- Two or more surcharges apply
- The building is old and depreciation rules kick in
