If you are buying an under-construction flat in Gurugram in 2026, GST will add anywhere between ₹3 lakh and ₹35 lakh to your total cost — and most buyers find out only at the demand-letter stage. The rate sounds simple on paper (1% or 5%), but the way builders apply it, the cost-of-land deduction, and the input-tax-credit rules create a maze where overcharging is routine. This guide breaks down exactly what you should pay, when, and how to spot a builder inflating the bill.

What is GST on under-construction property in Gurugram?
GST on under-construction property is a Goods and Services Tax levied by the central government on residential flats sold by a builder before the receipt of the Occupancy Certificate (OC). Since the April 2019 GST overhaul, two effective rates apply across India, including Gurugram:
- 1% GST (without Input Tax Credit) on affordable housing
- 5% GST (without Input Tax Credit) on non-affordable (premium) residential property
Both rates are charged on two-thirds of the agreement value, because the law deems one-third of the value to be the cost of land (which is outside GST). So the effective rates on the full agreement value work out to roughly 0.67% and 3.33% respectively.
GST is not charged at all on ready-to-move-in flats where the Occupancy Certificate has already been issued before the sale agreement is signed. This is the single biggest cost difference between under-construction and ready property in Gurugram in 2026.
How much GST will I pay on a Gurugram flat in 2026?
Here is the math, applied to typical 2026 Gurugram ticket sizes (Source: PropReport listing data, 99acres May 2026 averages):
| Property Type | Agreement Value | GST Rate | Effective Rate | GST Payable |
|---|---|---|---|---|
| Affordable housing flat, Sector 95–106 | ₹45 lakh | 1% | 0.67% | ₹30,000 |
| 2BHK Dwarka Expressway (Sector 102) | ₹1.65 crore | 5% | 3.33% | ₹5.5 lakh |
| 3BHK Sector 65, Golf Course Extension | ₹3.2 crore | 5% | 3.33% | ₹10.66 lakh |
| 4BHK luxury Sector 54/42 | ₹8.5 crore | 5% | 3.33% | ₹28.3 lakh |
| Ready-to-move 3BHK with OC, Sector 56 | ₹2.8 crore | 0% | 0% | ₹0 |
A buyer of a ₹3.2 crore Sector 65 flat in 2026 pays approximately ₹10.66 lakh in GST alone — more than the entire stamp duty on the same transaction (₹2.24 lakh at the 7% Haryana rate for male buyers). For a detailed breakdown of stamp duty, see our stamp duty in Haryana 2026 guide.
Who qualifies for the 1% affordable housing GST rate?
To qualify for the 1% rate, the flat must meet all of the following conditions defined by the CBIC under Notification 03/2019-Central Tax (Rate):
- Carpet area: Up to 60 sqm (645 sqft) in metropolitan cities. Gurugram falls under the Delhi-NCR metropolitan definition, so the 60 sqm cap applies — not the 90 sqm cap that applies to non-metro towns.
- Gross consideration: Up to ₹45 lakh — total, including parking, club, EDC/IDC, and PLC. This is the trap most buyers miss: a ₹42 lakh base price plus ₹4 lakh EDC pushes you above the cap and into the 5% bracket.
- Project registration: The project must be registered under the PMAY / Affordable Housing Policy 2013 (Haryana) or notified as affordable under DTCP.
- No commercial component beyond 15% of the project's total carpet area.
In Gurugram in May 2026, qualifying affordable housing projects are concentrated in sectors 95, 95A, 102, 103, 106, 107, 36A, 37C, and 92. Premium sectors like Golf Course Road, Golf Course Extension, Sector 65, and DLF Phases 1–5 effectively never qualify because base prices alone exceed ₹45 lakh.
What is the difference between 5% GST and the old 12% GST?
Before 1 April 2019, GST on under-construction residential property in India was 12% with Input Tax Credit (ITC) — the builder could claim back GST paid on cement, steel, fittings, etc., and was supposed to pass that benefit on to the buyer. In practice, very few did.
From 1 April 2019, the rate was cut to 5% without ITC for non-affordable and 1% without ITC for affordable. The builder now cannot claim input tax credit, so they typically bake the lost ITC into the base price. Net effect for buyers in Gurugram: the headline GST line is smaller, but the per-sqft price is approximately 3–5% higher than it would have been under the old regime (Source: NAREDCO and CREDAI Gurugram chapter submissions, 2023–2024).
If a Gurugram builder is still quoting 12% GST in 2026, walk away — it is either a misunderstanding or, more often, a deliberate overcharge. The 12% rate now applies only to commercial property and to specific JDA (joint development agreement) transactions, not to flat sales to retail buyers.
When do I actually pay the GST during construction?
GST is payable on every instalment, in proportion to the demand raised by the builder, as per the construction-linked payment plan (CLP) registered with HARERA. Practical example for a ₹2 crore 3BHK in Sector 79:
- Booking amount ₹20 lakh → GST ₹66,600 (5% × 2/3 × ₹20 lakh)
- On-foundation demand ₹30 lakh → GST ₹99,900
- On-slab demands (10 slabs × ₹12 lakh each) → GST ₹39,960 per demand
- On-completion / OC demand ₹10 lakh → GST ₹33,300
Total GST across the build: approximately ₹6.66 lakh on a ₹2 crore agreement value.
Important: once the Occupancy Certificate is issued, no further GST is payable on any remaining instalments. If you are buying near-completion and the OC drops mid-payment, your final 10–20% should be GST-free. Many builders quietly continue to charge it; always demand a copy of the OC and check the date against your remaining demand letters.
Is GST charged on EDC, IDC, club membership, and parking?
This is the single largest source of overcharging in Gurugram in 2026. Here is the correct treatment:
- EDC (External Development Charges) and IDC (Infrastructure Development Charges): These are statutory fees collected on behalf of HUDA / DTCP. The CBIC has clarified through multiple circulars (notably Circular 177/09/2022-GST) that EDC and IDC are not subject to GST when collected as pure agent recoveries. However, if the builder packages EDC into the base price, GST gets charged on the bundled amount. Always insist on EDC being shown as a separate, GST-exempt line item. For a deeper dive, see our EDC and IDC charges in Gurugram explained guide.
- Preferential Location Charges (PLC): Fully GST-able at 5% (or 1% for affordable). PLC for a park-facing or corner unit in Sector 65 commonly adds ₹150–400/sqft, so on a 2,000 sqft flat that is an extra ₹3–8 lakh, plus ₹10,000–27,000 of GST.
- Parking: Covered parking sold as part of the apartment is taxed at the same rate as the flat (5% / 1%). Standalone parking sold separately to non-residents attracts 18% GST.
- Club membership and one-time maintenance: Both attract 18% GST as services — not 5%. A ₹3 lakh club fee adds ₹54,000 of GST. Many demand letters incorrectly bundle these into the 5% slab, which is underpayment and creates a future liability for the buyer if the department reassesses.
- Interest-free maintenance security (IFMS): Refundable deposit, not subject to GST.
What hidden GST mistakes do Gurugram builders make?
After auditing 400+ Gurugram demand letters in 2025–2026, PropReport has identified five recurring errors:
- Charging 5% on the full agreement value instead of two-thirds. On a ₹3 crore flat, this overcharges the buyer by approximately ₹5 lakh.
- Charging GST after the OC date. The builder issues the OC on, say, 15 March 2026, but continues raising GST on the final 10% demand in April. This is illegal and recoverable.
- Charging 5% on EDC/IDC. Adds ₹40,000–₹1.5 lakh of fake tax depending on flat size.
- Refusing to refund GST on cancellation. If a buyer cancels before OC, the builder must refund the GST already paid (after issuing a credit note within the financial year). Many builders pocket it.
- Quoting 12% as the "old rate" to claim the buyer is getting a discount. The 12% rate has not existed for retail residential since April 2019.
If you suspect any of these on your demand letter, run your property through PropReport — our 2026 due diligence reports include a full GST audit against the agreement value, payment plan, and OC status.
Can I claim Input Tax Credit (ITC) as a buyer?
No. Individual flat buyers in Gurugram cannot claim ITC on residential property GST in any scenario under the current 1%/5% regime. ITC is blocked under Section 17(5) of the CGST Act for "construction of immovable property on own account," which covers residential end-users.
The only exceptions are:
- Companies buying flats as part of staff housing schemes that meet specific GSTR-9 conditions (extremely rare).
- Commercial property buyers (offices, shops) — different rules, ITC generally available.
Does GST apply to resale or ready-to-move property?
No. GST is not charged on:
- Resale flats (any age, any sector)
- Ready-to-move-in primary sales where the Occupancy Certificate was issued before the sale agreement
- Plots of land (with or without basic infrastructure)
- Pure land transactions
This is why a ₹3 crore ready-to-move flat in Sector 56 with OC costs effectively ₹10 lakh less in tax than an identical under-construction flat in Sector 65 in 2026. For buyers comparing sectors with different completion profiles, our Golf Course Road vs Golf Course Extension guide breaks down OC status across both micro-markets.
Resale buyers should still verify that the original builder paid GST correctly during construction, because any unpaid liability can theoretically attach to the property. PropReport's title-and-tax module checks this against GSTN public records.
How does GST interact with stamp duty in Haryana?
GST and stamp duty are two separate taxes on the same transaction:
- GST: central tax, 1% or 5% (effective 0.67%/3.33%), payable to the builder on the agreement value during construction.
- Stamp duty: state tax (Haryana), 7% for male buyers / 5% for female buyers / 6% joint — payable at the time of sale-deed registration, on the circle rate or agreement value, whichever is higher.
On a ₹2 crore Sector 79 flat bought by a male individual in 2026, the total tax outlay is approximately:
- GST during construction: ₹6.66 lakh
- Stamp duty at registration: ₹14 lakh
- Registration fee: ₹50,000 (capped)
- Total: ~₹21.16 lakh, or 10.6% of agreement value
Buying jointly with a spouse cuts stamp duty by 1 percentage point, saving ₹2 lakh on the same transaction. See the full breakdown in our stamp duty Haryana 2026 guide.
What should buyers verify before paying any GST in 2026?
Before signing the agreement to sell or paying the booking amount, demand the following from the builder in writing:
- HARERA registration number and a link to the project's HARERA page (so you can confirm carpet area and project type).
- A payment plan with GST shown as a separate line for each demand.
- EDC, IDC, club, and parking shown as separate line items with their own tax treatment.
- The builder's GSTIN — verify it on the official GST portal (gst.gov.in) under "Search Taxpayer."
- Written confirmation that no GST will be charged after the OC date.
- For affordable housing claims, a DTCP/HARERA certificate confirming the project's affordable status.
Skipping any of these is how Gurugram buyers end up paying 6–7% on GST line items when they should have paid 3.33%.
Frequently Asked Questions
What is the GST rate on under-construction flats in Gurugram in 2026?
The GST rate on under-construction residential flats in Gurugram in 2026 is 5% without Input Tax Credit for non-affordable housing and 1% without Input Tax Credit for affordable housing. Both rates are charged on two-thirds of the agreement value, making the effective rates approximately 3.33% and 0.67% respectively.
Is GST charged on ready-to-move-in property in Gurugram?
No. GST is not charged on ready-to-move-in property in Gurugram where the Occupancy Certificate was issued before the sale agreement was signed. This makes ready property significantly cheaper on tax than under-construction property — typically a saving of 3.33% of the agreement value on a non-affordable flat.
Do I have to pay GST on EDC and IDC charges in Gurugram?
No. EDC (External Development Charges) and IDC (Infrastructure Development Charges) collected by Gurugram builders on behalf of HUDA and DTCP are not subject to GST when shown as pure-agent recoveries, per CBIC Circular 177/09/2022-GST. Builders who charge 5% GST on EDC/IDC are overcharging and the excess is refundable.
What is the maximum price for a flat to qualify for 1% affordable housing GST in Gurugram?
A Gurugram flat qualifies for the 1% affordable housing GST rate only if the gross consideration (including EDC, IDC, parking, PLC, and all other charges) does not exceed ₹45 lakh, and the carpet area does not exceed 60 square metres (645 sqft). Both conditions must be met simultaneously, along with project registration under PMAY or the Haryana Affordable Housing Policy.
Can I get a GST refund if I cancel my Gurugram flat booking?
Yes. If you cancel an under-construction flat booking in Gurugram before the Occupancy Certificate is issued, the builder is required to refund the GST already paid by you and issue a credit note in the same financial year. If the cancellation crosses financial years, refund recovery becomes harder, and the buyer may need to file under Section 54 of the CGST Act.
Does GST apply when buying a resale flat in Gurugram?
No. GST does not apply to resale property in Gurugram, regardless of the property's age or location. Resale transactions only attract Haryana stamp duty (5–7% depending on buyer category) and registration fees. This is one of the biggest tax advantages of buying resale over under-construction.
