GST on Home Purchase in India: What You Actually Pay

Does GST Apply to Every Home Purchase?

No — and this is the most important thing to understand first.

GST applies only to under-construction properties — flats, villas, or row houses where construction is ongoing at the time of sale. It does not apply to:

• Ready-to-move-in (completed) properties where the builder has obtained a Completion Certificate (CC) or Occupancy Certificate (OC).
• Resale transactions between individual buyers and sellers.
• Pure land transactions (though some composite deals have implications).

If you buy a flat that already has its OC, GST is zero. This is why many buyers specifically target completed projects.

GST Rates on Under-Construction Properties

The GST Council revised rates in April 2019. Current applicable rates are:

Note: Input Tax Credit (ITC) is not available to builders for residential projects. This means the builder cannot offset GST paid on cement, steel, and services — so part of that cost is embedded in the sale price.

What Qualifies as "Affordable Housing"?

The 1% concessional rate applies to units that meet all of the following criteria:

• Metropolitan cities (Delhi NCR, Mumbai MMR, Chennai, Kolkata, Bengaluru, Hyderabad, Pune): Carpet area ≤ 60 sq m and price ≤ ₹45 lakh
• Other cities and towns: Carpet area ≤ 90 sq m and price ≤ ₹45 lakh

This definition is deliberately strict. In Mumbai, a ₹44 lakh flat with 61 sq m carpet area is not affordable housing for GST purposes — it falls under the 5% slab.

How GST Is Calculated: Real Examples

Example 1 — Affordable Housing in Pune

A 2BHK flat with 58 sq m carpet area priced at ₹42 lakh in a RERA-registered project under construction.

• Qualifies as affordable housing (area ≤ 60 sq m, price ≤ ₹45 lakh)
• GST = 1% × ₹42,00,000 = ₹42,000
• Total payable = ₹42,42,000

Example 2 — Non-Affordable Under-Construction in Mumbai

A 2BHK flat with 72 sq m carpet area priced at ₹1.2 crore in Thane.

• Not affordable housing (area exceeds 60 sq m)
• GST = 5% × ₹1,20,00,000 = ₹6,00,000
• Total payable = ₹1,26,00,000

Example 3 — Ready-to-Move Flat in Bengaluru

A flat with OC priced at ₹85 lakh.

• GST = ₹0
• Total payable = ₹85,00,000 (plus stamp duty and registration)

GST on Parking, Club Membership, and Extras

GST applies to the entire consideration paid to the builder, not just the base flat price. This includes:

• Parking charges: 5% GST if bundled with under-construction flat
• Preferential Location Charges (PLC): 5% GST
• Club membership fees (if mandatory at the time of flat purchase): 5% GST
• Maintenance deposits collected at the time of possession: These are typically outside GST scope but check the structure with your builder.

Many builders quote a base price for the flat and then add these charges separately. Ensure you get a complete cost sheet to calculate total GST liability.

GST and Stamp Duty: No Double-Dipping?

GST and stamp duty are both levied but on different bases:

• GST applies to the construction/development service component and is paid to the central/state governments through the GST mechanism.
• Stamp duty applies to the value of the property being transferred and is a state levy.

There is no offset between the two — you pay both independently. On a ₹1 crore under-construction flat in Maharashtra, you might pay ₹5 lakh GST (5%) and ₹6 lakh stamp duty (6%) — a combined ₹11 lakh in government charges.

Is GST Input Tax Credit Available to Buyers?

No. Individual residential buyers cannot claim ITC on GST paid on home purchase. GST paid on the flat is a pure cost. This is different from commercial property purchases, where registered businesses buying shops or offices can claim ITC.

Practical Tips for Homebuyers

1. Prefer completed projects if you want to avoid GST entirely — but balance this against RERA protections, which apply only to under-construction projects.
2. Negotiate the cost sheet carefully: Ensure the builder provides a breakup of base price, PLC, parking, and applicable GST — each line item separately.
3. Check the carpet area precisely: The difference between 59 sq m and 61 sq m can mean the difference between 1% and 5% GST on the full amount.
4. Get GST invoice from builder: You are entitled to a GST invoice for every payment. Maintain these for your records — they are relevant for capital gains computation when you sell.
5. Verify builder's GST registration: The builder's GSTIN should appear on your payment receipts and sale agreement.
