GST is the silent ₹75 lakh line item in a Worli under-construction purchase agreement. On a ₹15 Cr UC ticket, the 5% GST charge adds ₹75 lakh to the headline price — a number large enough to materially shift the UC-vs-resale economics, but small enough to be glossed over in the agreement annexures most buyers do not read carefully. This guide walks the actual math, the input tax credit question that confuses most buyers, the 1% affordable carve-out (which never applies to Worli), and the structuring decisions that decide whether you save or spend an extra 5%.

The Three GST Rates — Pick Your Scenario
Indian residential property GST has three rate slabs since the April 2019 restructuring. Only one applies to Worli buyers. Knowing which one and why matters because the agreement will state the rate but rarely explain the reasoning.
| GST Rate | Property Type | Input Tax Credit | Worli Application |
|---|---|---|---|
| 5% | Non-affordable residential (carpet >60 sqm metro / >90 sqm non-metro, OR price >₹45 lakh) | No ITC available to developer | Default for Worli — applies to virtually all Worli UC |
| 1% | Affordable residential (carpet <60 sqm metro AND price <₹45 lakh) | No ITC available to developer | Never applies to Worli (price floor exceeded by every project) |
| 12% (legacy) | Non-affordable residential under pre-April-2019 regime | ITC was available | Only on a handful of grandfathered legacy Worli projects |
For 99% of Worli under-construction buyers in 2026, the operative rate is 5% without input tax credit. The 1% affordable rate is structurally unavailable in Worli because the price floor of ₹45 lakh is below the cheapest Worli unit (Hubtown Celeste 1 BHK at ₹1.99 Cr). The 12% legacy rate applies only to projects that were under construction at the April 2019 transition cut-off and explicitly opted to retain the old regime — this is now a tiny pool, mostly older Lodha World Towers tower phases and a small slice of Omkar 1973 inventory.
What "Without Input Tax Credit" Actually Means for the Buyer
The 5% GST rate looks low on paper compared to the legacy 12%. The hidden cost: the developer cannot claim input tax credit on the GST it pays to suppliers (cement, steel, contractors, services). That embedded GST cost flows through into the project budget and ultimately the price the developer quotes to the buyer. Estimates from CREDAI and Knight Frank suggest the embedded effective tax cost is roughly 6-9% of the project hard cost — passed to the buyer in the headline ask.
PROPERTY BUTLER GST CALL
The 5%-without-ITC structure is buyer-unfriendly relative to the legacy 12%-with-ITC structure for Worli specifically. Worli's high construction-cost base (Class A finishes, premium structural specs) means the embedded GST cost the developer absorbs is meaningful. For a 4 BHK at ₹15 Cr UC, total tax burden (5% headline GST + ~3-5% embedded GST in the construction cost) is roughly 8-10% of the all-in price — meaningfully higher than the headline 5% suggests. There is no buyer remedy; this is the architecture of the post-2019 regime. The economic case for ready-to-move resale becomes correspondingly stronger.
UC vs Ready Resale — The 5% Net Economics
The single most important GST-driven structuring decision a Worli buyer makes: under-construction with 5% GST, or ready resale with zero GST. Let us work the math on a Worli 3 BHK at the same effective ticket size.
| Cost Item | UC at ₹15 Cr | Ready Resale at ₹16 Cr |
|---|---|---|
| Headline ticket | ₹15.00 Cr | ₹16.00 Cr |
| GST | ₹75 L (5%) | ₹0 |
| Stamp duty (6%, on agreement value) | ₹90 L | ₹96 L |
| Registration (1%, capped ₹30 k) | ₹30 k | ₹30 k |
| Brokerage on resale (~1%) | ₹0 (UC fees built into developer pricing) | ₹16 L |
| All-in cost | ₹16.65 Cr | ₹17.12 Cr |
| Plus: 4-7 yr possession wait (UC), opportunity cost / rental gap | Significant | Zero — immediate possession |
The headline difference is ₹1 Cr higher ticket for ready resale, but the all-in difference compresses to ₹47 lakh once GST is factored in — before considering possession-wait opportunity cost and rental income on the ready alternative. For a Worli buyer who values immediate possession or who would otherwise need to pay rent during the UC waiting period, ready resale frequently wins on net economics despite the higher headline ticket. This is the structural reason flagship ready Lodha towers (World Towers, Trump, Adrina) trade at a 15-25% premium to UC alternatives.
The OC Pivot — Why Timing Your UC Purchase Matters
GST is charged only on under-construction property — defined as property where the occupation certificate (OC) has not yet been issued. Once the developer obtains the OC, the same flat becomes "ready" and any subsequent sale to a new buyer attracts zero GST. This creates a structural pricing inflection at the OC moment.
Three buyer scenarios this affects:
- Booking pre-OC vs post-OC at the same project — the pre-OC unit costs 5% more in GST. If the project is within 6-12 months of OC, the wait may be worth the 5% saving.
- Resale of a unit purchased pre-OC and resold post-OC — the original buyer absorbed the 5% GST; the resale buyer does not. The seller cannot recover the 5% but it is part of the seller's acquisition cost basis for capital gains computation.
- Investor flip strategy — some Worli investors deliberately book pre-OC and resell within 90 days of OC, capturing the appreciation but absorbing the 5% GST in their own cost basis. Math works only when the appreciation rate exceeds the GST + holding cost.

WhatsApp Property ButlerFrequently Asked Questions
Can I claim back the GST paid on a Worli under-construction purchase?
No, under the current 5%-without-ITC regime, neither the developer nor the buyer can recover the GST charged on the residential property purchase. The GST flows through to the buyer as a final tax cost. The legacy 12%-with-ITC regime allowed developers to claim ITC on input GST, with the savings passed to buyers in lower headline pricing — but that regime was withdrawn in April 2019. The exception: commercial property (office space) under a different GST treatment can allow ITC claims by businesses using the property for taxable supplies.
If I cancel my Worli under-construction booking, do I get the GST back?
Yes, in most cases. If you cancel the booking before possession and the developer refunds the consideration, the developer is also required to refund the GST charged. The mechanism: developer files a credit note in their GST return reversing the original GST liability, and refunds the GST amount to you alongside the principal. Some developers attempt to retain the GST as a “cancellation cost” — this is not GST-law compliant and is challengeable. Always confirm in writing that any cancellation refund includes the GST component before signing the cancellation deed.
Does the 5% GST apply to the carpet area or saleable area?
GST applies to the consideration (price) paid for the property, not directly to the area. So the 5% applies to whatever total amount appears on the agreement, regardless of whether that price is quoted per carpet square foot or per saleable square foot. However, the affordable-housing eligibility test (which would qualify the property for the 1% rate — not applicable in Worli but relevant elsewhere) is based on carpet area: under 60 sqm in metro, under 90 sqm in non-metro. Worli flats categorically exceed both the carpet and price thresholds for the affordable rate.
Why is GST not charged on ready-to-move properties?
Under GST law, the sale of completed property is treated as the transfer of an immovable asset, not a ‘supply’ for GST purposes. The legal trigger for GST on real estate is the under-construction supply of services (construction). Once the OC is issued, the construction supply is complete; subsequent sales are immovable property transfers governed by stamp duty and registration alone, not GST. This is why ready resale is GST-free and why developers structure pricing to incentivise pre-OC bookings (where the buyer absorbs the GST) versus post-OC resale (where they cannot pass on the GST embedded in their cost base).
Are the parking and clubhouse charges also subject to 5% GST?
Yes, when bundled with the under-construction property purchase, parking allotment fees, clubhouse / amenity charges, and Preferential Location Charges (PLC) are all subject to the same 5% GST rate as the principal property consideration. Developers sometimes structure these as separate line items in the agreement to manage the buyer's perception of the headline price — but the GST treatment is uniform.
