GST on Under-Construction Properties: Homebuyers Must Know (2025)

What is GST on Under-Construction Properties?

Introduced in 2017, GST subsumed various indirect taxes into one unified system. When it comes to real estate, the government levies GST only on under-construction properties, not on ready-to-move-in homes.

Initially, GST on under-construction properties was charged at 12%, but after the 33rd GST Council amendment, it was revised:

  • 5% GST for non-affordable under-construction residential properties (without Input Tax Credit)
  • 1% GST for affordable under-construction residential properties (without ITC)

Note: No GST is applicable if the property has received a completion certificate.

How to Calculate GST on Under-Construction Properties?

To calculate GST, remember that land cost is exempted. Only two-thirds of the total property value is considered taxable.

How to Calculate GST on Under-Construction Properties?

Formula:
GST = (Total Property Value × 2/3) × Applicable GST Rate

Affordable Housing Example:

  • Property Value = ₹42,00,000
  • Taxable Value = 42,00,000 × 2/3 = ₹28,00,000
  • GST = 1% of ₹28,00,000 = ₹28,000

Non-Affordable Housing Example:

  • Property Value = ₹75,00,000
  • Taxable Value = 75,00,000 × 2/3 = ₹50,00,000
  • GST = 5% of ₹50,00,000 = ₹2,50,000

Key Details You Must Know About GST on Under-Construction Properties

Key Details You Must Know About GST on Under-Construction Properties

1. GST is NOT applicable on completed properties

If the builder has received a Completion Certificate (CC), you don’t have to pay GST.

2. Different slabs for affordable vs. regular housing

  • Affordable Housing (up to ₹45 lakhs): 1% GST
  • Others: 5% GST

3. Commercial Properties have 12% GST

If you’re investing in a shop, office, or any other commercial space, you’ll be charged 12% GST.

4. Land value is excluded

These are mandatory and separate from GST. Usually, they add 5%-7% more to the total cost.

Some builders agree to absorb GST, reducing your overall property cost. Always ask.

Financial Impact of GST on Under-Construction Properties

  • Saves money by excluding land value from the tax base.
  • Clearer tax structure with no confusion between VAT, service tax, etc.

  • You don’t get Input Tax Credit (ITC) under the new GST scheme.
  • Property cost = Base Price + GST + Stamp Duty + Registration
