How do you use the parking cost calculator?
- Enter the flat’s price without parking, whether the slot is covered or open, the number of slots and the price per slot.
- Pick the GST rate shown on the builder’s cost sheet. A flat bought after the occupancy certificate usually carries no GST.
- New flat or resale, other one-off parking charges and the stamp duty and registration rates are under “Adjust rates and other charges”.
What does parking really cost?
The price per slot is only the start. Parking bought with a flat goes into the agreement and the sale deed, so it raises the value on which stamp duty, cess, surcharge and registration are charged. On an under-construction flat the builder also bills GST on it. Together these add 12.6% to a ₹ 3 lakh covered slot with GST at 5%.
What a builder can sell matters too. Section 2(n) of the RERA Act counts open parking areas as common areas, which belong to all the owners, so open parking should not be sold as a separate item. A covered slot or garage shown in the sanctioned plan can be allotted for a price.
How the cost is worked out
Slots × price per slotSlot price × GST rate on your cost sheetCharges on (flat + parking) − charges on the flat aloneSlot price + GST + extra charges + other chargesWorked example: ₹ 3 lakh slot with a ₹ 1 crore flat
GST at 5% is ₹ 15,000. Adding ₹ 3 lakh to the deed value raises stamp duty, cess, surcharge and registration by ₹ 22,800, at 5.6% duty with cess and surcharge plus 2% registration. The slot costs ₹ 3,37,800 all in, 3.4% of the flat price.
Worked example: ₹ 3 lakh slot with a ₹ 40 lakh new flat, no GST
With the flat and parking together at ₹ 43 lakh, the first-sale duty of 3% applies, so the extra charges are ₹ 16,080 and the slot costs ₹ 3,16,080 all in.
Parking cost at each GST rate
| GST | GST amount | Extra stamp duty, registration | All-in cost |
|---|---|---|---|
| None | ₹ 0 | ₹ 22,800 | ₹ 3,22,800 |
| 5% | ₹ 15,000 | ₹ 22,800 | ₹ 3,37,800 |
| 18% | ₹ 54,000 | ₹ 22,800 | ₹ 3,76,800 |
What should you keep in mind?
- Ask for the slot number, its size and its place in the sanctioned plan, and make sure all three are in the agreement and the sale deed.
- The GST rate on separately priced parking has been disputed in advance rulings. Ask the builder which rate applies and confirm it with your Chartered Accountant.
- If a builder charges for open parking, have your lawyer look at it before you pay.
