Under GST 2.0 effective 22 September 2025, the rate structure for real estate has been rationalized. Residential under-construction flats attract 5% GST without ITC. Affordable housing remains at 1% without ITC. Commercial under-construction projects now attract 18% GST with ITC (revised from 12%). Ready-to-move properties remain exempt.
What is GST for Builders?
How the Goods and Services Tax applies to builders, developers, and promoters in India's real estate sector.
GST for builders refers to the Goods and Services Tax levied on the construction and sale of real estate properties — specifically those that are still under construction at the time of sale. The GST framework for builders in India is governed primarily by the CGST Act 2017, Notification 11/2017-CT(R), Notification 3/2019-CT(R), and GST 2.0 revisions effective 22 September 2025.
Before GST, builders faced a complex structure of Service Tax, VAT, stamp duty, and other levies — leading to cascading taxes and significant compliance burden. GST unified most of these under a single framework, though the real estate sector has always had unique rules distinguishing under-construction from completed properties.
Key Principle: GST applies only when construction is in progress — i.e., the property is under construction and the buyer makes payments before the builder receives an Occupancy Certificate (OC) or Completion Certificate (CC) from the competent authority. Once OC/CC is issued, the sale is treated as a transfer of immovable property — exempt from GST as no supply of goods or services is involved.
For FY 2026-27, builders must operate under the post-GST 2.0 framework, where most construction services have been rationalized to the 18% slab for commercial works, while residential buyer-facing rates remain at 5% (non-affordable) and 1% (affordable housing) — both without ITC.
GST Registration Requirements for Builders
When GST registration is mandatory for builders and real estate developers in India.
| Category | Threshold | Registration |
|---|---|---|
| Builder / developer (services + goods supply) | ₹20 lakh/year aggregate turnover | Mandatory above threshold |
| Special category state builders (NE states + Uttarakhand/HP) | ₹10 lakh/year | Mandatory above threshold |
| Builder executing inter-state projects | No threshold | Mandatory regardless |
| Builder liable under RCM (JDA / TDR / GTA) | No threshold | Mandatory |
| Builder with Govt. TDS deduction u/s 51 | No threshold | Mandatory |
| Builder below threshold — voluntary | Below ₹20 lakh | Advisable — enables ITC on commercial projects |
Important for JDA Projects: Even if a builder's direct sales turnover is below ₹20 lakh, if the builder receives development rights under a JDA and the deemed supply value under GST exceeds the threshold, registration becomes mandatory. Always calculate aggregate turnover including RCM supplies. Refer: Aggregate Turnover Under GST.

GST on Residential Construction Projects
How GST applies to builders developing residential apartments, flats, and housing societies in India.
For residential construction projects, GST applies at the point of sale while the property is still under construction. The applicable rate depends on whether the project qualifies as affordable housing or falls under the general residential category.
🏘️ Non-Affordable Residential (5% GST)
- GST Rate: 5% without ITC
- Applicable to all residential flats, apartments, row houses not meeting affordable housing criteria
- GST charged on the booking amount / sale consideration (excluding land value)
- Land value typically deducted as 1/3rd of total consideration for GST computation
- Builder CANNOT claim ITC on cement, steel, contractor invoices
- Rate in force since 01.04.2019; unchanged under GST 2.0
- Applies to projects launched on or after 01.04.2019
🏠 Affordable Housing (1% GST)
- GST Rate: 1% without ITC
- Carpet area ≤ 60 sqm in metro cities (Delhi NCR, Mumbai, Bengaluru, Chennai, Hyderabad, Kolkata)
- Carpet area ≤ 90 sqm in all other cities and towns
- Gross consideration ≤ ₹45 lakh per unit
- Project must be under PMAY or equivalent scheme
- Builder CANNOT claim ITC on inputs
- Unchanged under GST 2.0
Land Value Deduction: GST on residential flat purchase is calculated on the construction value only — not on the total sale consideration. As per Rule 42 of CGST Rules and CBIC guidance, 1/3rd of the total value is deemed to be the land component and is excluded from the GST base. So if a flat costs ₹90 lakh, GST is charged on ₹60 lakh (2/3rds) at 5% = ₹3 lakh GST.
GST on Commercial Construction Projects
GST rates and ITC rules for builders developing commercial offices, shops, malls, and complexes.
Commercial under-construction properties — offices, shops, showrooms, commercial complexes, and mixed-use commercial units — are taxed at 18% GST with ITC effective 22 September 2025. This is a significant revision from the earlier 12% rate under the pre-GST 2.0 regime.
GST 2.0 Key Change — Commercial Projects: The 12% rate on commercial under-construction property sales has been revised to 18% effective 22 September 2025. Builders who have ongoing commercial projects must update all sale agreements, payment schedules, and invoices to reflect 18% GST for payments received on or after 22 September 2025. Seek legal advice for transition period treatment.
| Commercial Property Type | Status | GST Rate (FY 2026-27) | ITC |
|---|---|---|---|
| Office spaces, commercial floors | Under construction | 18% | Available |
| Retail shops, showrooms | Under construction | 18% | Available |
| Commercial units in mixed-use projects | Under construction | 18% | Available |
| IT parks, tech parks | Under construction | 18% | Available |
| Any commercial property | Post OC / CC (ready) | Nil / Exempt | N/A |
| Renting commercial property | Ongoing | 18% on rent | On rental expenses |
ITC Benefit for Commercial Builders: Builders developing commercial properties under the 18% scheme CAN claim ITC on cement, steel, contractor invoices, architect fees, and other construction inputs — reducing their effective tax outflow. This is a major advantage over residential builders under the 5% no-ITC scheme. Proper ITC tracking and GSTR-2B reconciliation is essential. Read: ITC Under GST — Complete Guide.
What is the GST Rate on Under Construction Flats?
The most commonly asked question — GST on under-construction flats, payment schedules, and calculation explained.
GST on under-construction flats is charged at the time each payment instalment is received by the builder — whether it is a booking amount, construction-linked payment, or demand payment. The rate depends on the type of project:
GST Calculation Example — Under Construction Flat
| Particulars | Non-Affordable (5%) | Affordable Housing (1%) |
|---|---|---|
| Total Sale Consideration | ₹90,00,000 | ₹40,00,000 |
| Less: Land Component (1/3rd) | ₹30,00,000 | ₹13,33,333 |
| Taxable Value (2/3rd) | ₹60,00,000 | ₹26,66,667 |
| GST Rate | 5% | 1% |
| GST Amount | ₹3,00,000 | ₹26,667 |
| Total Amount Paid by Buyer | ₹93,00,000 | ₹40,26,667 |
Note on Payment Schedule: GST is applicable on each instalment received before OC/CC. If any instalment is received after the builder obtains OC/CC, that payment is NOT subject to GST. Builders must carefully track payment timing vis-à-vis the OC receipt date for each project.
Is GST Applicable on Ready-to-Move Properties?
Why ready-to-move properties enjoy a complete GST exemption — and what triggers it.
No — GST is not applicable on ready-to-move-in properties. Once a builder has obtained an Occupancy Certificate (OC) or Completion Certificate (CC) from the competent municipal authority, the sale of the property is treated as a transfer of immovable property — not a supply of goods or services — and is therefore completely outside the scope of GST.
✅ Ready-to-Move — Exempt from GST
- OC / CC received from municipal authority before sale
- Property is fully constructed and legally habitable
- All payments made after OC/CC date — no GST
- Applicable to both residential and commercial units
- Buyer pays Stamp Duty + Registration charges only
- No GST on resale of completed properties either
⚠️ Key Caution Points
- If even 1 rupee is received BEFORE OC/CC, that payment is subject to GST
- Provisional OC ≠ Completion Certificate — verify exact document
- Builder's self-certification is NOT equivalent to OC/CC
- For part-payments before OC and balance after OC — GST applies only on pre-OC payments
- Builders must maintain OC/CC copies for all projects to defend audit
Practical Tip for Builders: Clearly mention in your sale agreements whether the property is under-construction (GST applicable) or ready-to-move (no GST). Misrepresentation of OC status to avoid GST collection from buyers constitutes tax evasion under Section 122 of the CGST Act and can attract penalties up to 100% of the tax amount.
GST on Affordable Housing Projects
Criteria, rates, and compliance for builders developing affordable housing under PMAY guidelines.
The government offers a concessional 1% GST rate without ITC for affordable housing projects to promote homeownership among low and middle-income groups. This rate has remained unchanged even under GST 2.0.
| Criterion | Metro Cities* | Non-Metro Cities / Towns |
|---|---|---|
| Maximum Carpet Area | 60 sqm (≈ 646 sq ft) | 90 sqm (≈ 968 sq ft) |
| Maximum Gross Value | ₹45 lakh per unit (all cities) | |
| GST Rate | 1% without ITC | |
| Scheme reference | PMAY (Pradhan Mantri Awas Yojana) or equivalent | |
| ITC to builder | Blocked — No ITC | |
*Metro cities: Delhi NCR (Delhi, Noida, Greater Noida, Ghaziabad, Gurugram, Faridabad), Mumbai (including MMR region), Bengaluru, Chennai, Hyderabad, and Kolkata.
ITC Trade-off — The Hidden Cost: While the 1% rate seems extremely attractive, the denial of ITC means all GST paid on cement (28%), steel (18%), sand (5%), contractor invoices (18%) becomes a direct cost for the builder — embedded into the project cost and ultimately passed on to the buyer. This "tax on tax" effect is a key policy debate in real estate GST. Builders should carefully evaluate whether the 1% no-ITC scheme or the ITC-eligible scheme (where applicable) is more beneficial for their specific project.
Works Contract Under GST for Builders
How builders are affected by works contract GST when engaging civil contractors for their projects.
Builders engage civil contractors, electrical contractors, plumbing contractors, and other specialist firms to execute their construction projects. These contractors raise GST invoices on the builder for works contract services under SAC 9954. Post-GST 2.0, all such works contract services attract 18% GST.
Key Rule: When a builder receives a works contract invoice from a contractor at 18% GST, whether the builder can claim ITC on it depends on the type of project:
🏢 Commercial Project Builder
Receives 18% GST invoice from contractor → CAN claim ITC on this invoice (18% works contract GST). This ITC is offset against the 18% GST charged to commercial buyers. Proper GSTR-2B reconciliation required.
🏠 Residential Project Builder (5%/1%)
Receives 18% GST invoice from contractor → CANNOT claim ITC — blocked under Section 17(5)(c) as the works contract services are used for construction of immovable property. This increases the construction cost for residential builders.
Mixed Projects (Residential + Commercial): For builders with projects containing both residential and commercial units, ITC must be bifurcated proportionately under Rule 42 of CGST Rules. ITC attributable to commercial portion is claimable; ITC attributable to residential portion is blocked. Maintain floor-wise or unit-wise cost allocation for accurate computation.
Can Builders Claim ITC Under GST?
ITC rules for builders — who can claim, who cannot, and what is blocked under Section 17(5).
| Builder Type / Project | ITC on Construction Inputs | ITC on Office Expenses | Reason |
|---|---|---|---|
| Residential builder — 5% new scheme | Blocked | Yes | Section 17(5) — opted new rate scheme |
| Affordable housing builder — 1% scheme | Blocked | Yes | Section 17(5) — opted 1% scheme |
| Commercial builder — 18% scheme | Yes — Full ITC | Yes | Taxable supply at 18% — ITC unrestricted |
| Mixed project (residential + commercial) | Proportionate Rule 42 | Yes | Apportion ITC as per Rule 42/43 |
| Pre-April 2019 ongoing project (old scheme) | Available if old rates opted | Yes | Old scheme — 8%/12% with ITC |
ITC Blocked Under Section 17(5)(c) & (d): Works contract services received by a builder for construction of immovable property for residential purposes — and goods/services used for such construction — are specifically blocked. This applies even if the builder is otherwise registered and filing returns. The block is absolute for residential builders under the new rate scheme. See: Blocked Credit Under Section 17(5).
GST on Joint Development Agreements (JDA)
The complex but critical GST treatment of JDAs — including landmark 2025 court rulings.
A Joint Development Agreement (JDA) is an arrangement where a landowner gives land to a developer/builder for construction. In return, the builder provides constructed units or monetary consideration to the landowner. GST treatment of JDAs has been one of the most litigated areas in real estate taxation.
🏛️ Landmark Bombay HC Ruling — April 8, 2025 (Shrinivasa Realcon Pvt. Ltd.): The Bombay High Court held that GST is not applicable on JDAs where no TDR/FSI is actually transferred. If a homeowner merely appoints a builder to develop land (without a formal TDR/FSI transfer), Entry 5B of Notification 11/2017 does not apply. No GST under RCM. Note: The Supreme Court stayed a related GST demand in October 2025 — the matter is still under judicial consideration. Builders should seek legal advice for their specific JDA structure.
| JDA Scenario | GST Applicability | Who Pays | Legal Reference |
|---|---|---|---|
| Landowner transfers TDR/FSI to developer | 18% GST under RCM | Developer / Builder (under RCM) | Notfn. 13/2017-CT(R) — Entry 5B |
| Landowner appoints builder (no TDR transfer) | No GST (Bombay HC 2025) | No liability (subject to Supreme Court) | Shrinivasa Realcon — Bombay HC April 2025 |
| Builder supplies constructed units to landowner | Deemed supply — 5% or 1% | Builder charges GST to landowner on units | Notfn. 11/2017 as amended |
| Builder receives monetary consideration under JDA | 5% / 18% on construction value | Builder on monetary portion | Circular 177/09/2022-TRU |
Practical Advice: JDA GST treatment is highly fact-specific. Given the ongoing Supreme Court proceedings (October 2025 stay order), builders involved in JDAs must obtain a written opinion from a qualified GST practitioner or advocate before finalizing their tax position.

GST on Transferable Development Rights (TDR)
How GST applies when TDR or FSI is purchased or transferred for real estate development.
Transferable Development Rights (TDR) and Floor Space Index (FSI) purchases by builders attract GST under the Reverse Charge Mechanism (RCM). The builder is required to pay GST on the value of TDR/FSI acquired for the project, irrespective of whether the seller is registered or unregistered.
| Type | GST Rate | Who Pays | ITC Availability |
|---|---|---|---|
| TDR / FSI purchase for residential project (new units for sale) | 18% under RCM | Builder / Promoter under RCM | Exempt from ITC (proportional to exempt units) |
| TDR / FSI purchase for commercial project | 18% under RCM | Builder / Promoter under RCM | Available for commercial portion |
| Additional FSI / premium FSI purchase | 18% under RCM | Builder / Promoter under RCM | Proportionate — Rule 42 |
| Long-term lease of land for development (≥ 30 years) | 18% GST | Lessor charges / RCM if unregistered | Available for commercial; blocked for residential |
RCM Compliance for TDR: When a builder purchases TDR/FSI, the seller (typically a landowner or government authority) may not be GST-registered. In such cases, the builder must self-assess and pay 18% GST under RCM in their GSTR-3B. Failure to pay RCM on TDR is a common audit point and triggers demand + interest + penalty. The value of TDR for GST computation is generally the purchase consideration paid. Read more: RCM Under GST — Full Applicability List.
GST on Construction Materials
GST rates on key construction materials that directly impact builders' project costs in FY 2026-27.
Understanding GST rates on construction materials is critical for builders — especially those under the 5% / 1% no-ITC residential scheme where these input taxes become embedded project costs passed on to buyers. Here are the latest rates on key materials:
Cement
Steel / Iron & Steel Products
Sand (natural)
Crushed Stone / Aggregates
Glass (safety / toughened)
Plumbing Fittings (PVC / CPVC)
Electrical Wires & Cables
Paints & Varnishes
Doors & Windows (wood)
Ready-Mix Concrete (RMC)
Aluminium Profiles / Sections
Tiles (ceramic / vitrified)
GST on Cement, Steel and Other Key Inputs
The ITC Denial Paradox: Cement attracts 28% GST — the highest slab. Steel attracts 18% GST. For a residential builder under the 5% no-ITC scheme, every ₹100 of cement costs an effective ₹128 (₹100 + ₹28 GST that cannot be recovered). This embedded tax becomes a project cost — a key reason why the abolition of ITC for residential builders has been criticized as inflationary for homebuyers.
| Material | HSN Code | Old GST Rate | New GST Rate (GST 2.0) | ITC — Residential Builder (5%/1%) | ITC — Commercial Builder (18%) |
|---|---|---|---|---|---|
| Cement (all types — OPC, PPC) | 2523 | 28% | 18% | Blocked | Available |
| Steel / TMT bars / Iron & Steel | 7213 | 18% | 18% (No change) | Blocked | Available |
| Sand (natural / crushed) | 2505 / 2517 | 12–18% | 5% | Blocked | Available |
| Fly Ash Bricks / Building Bricks / Roofing Tiles | 6815 / 6901 / 6904 / 6905 | 5–18% | 12% (Notfn. 14/2025-CT(R) w.e.f. 22 Sept 2025) | Blocked | Available |
| Ready Mix Concrete (RMC) | 3824 | 28% | 18% | Blocked | Available |
| Electrical Wires, Cables & Fittings | 8544 | 18% | 18% (No change) | Blocked | Available |
| Ceramic / Vitrified Tiles | 6907 | 28% | 18% | Blocked | Available |
| Paints, Varnishes & Coatings | 3208 / 3209 | 28% | 18% | Blocked | Available |
| Marble & Granite (raw / rough blocks) | 2515 | 12–18% | 5% | Blocked | Available |
| Marble & Granite (polished slabs / tiles) | 6802 | 28% | 18% | Blocked | Available |
⚠️ Rates effective 22 September 2025 as per GST 2.0 — Notification 14/2025-CT(R) and related notifications. Always verify with the latest CBIC GST notifications before invoicing.
GST Invoice Requirements for Builders
What builders must include on every GST invoice — legal requirements under Section 31 and Rule 46 of CGST Rules.
Every GST-registered builder must issue a Tax Invoice for each payment received from a buyer before OC/CC. The invoice must comply with Section 31 of the CGST Act and Rule 46 of the CGST Rules. Key mandatory particulars:
📄 Mandatory Invoice Fields
- Builder's name, address, and GSTIN
- Consecutive unique serial number (max 16 characters)
- Date of issue
- Buyer's name, address, and GSTIN (if registered)
- SAC Code 9954 (Construction Services)
- Description: type of unit, project name, floor, unit no.
- Taxable value (2/3rd of consideration — post land deduction)
- GST rate (1% or 5% or 18%) + amount separately (CGST + SGST / IGST)
- Place of Supply (state where project is located)
- Total amount payable including GST
- Signature / digital signature of authorized person
⚠️ Common Invoice Errors by Builders
- Charging GST on full sale value without deducting 1/3rd land value
- Not issuing invoice within 30 days of payment receipt
- Wrong Place of Supply (should be property location, not buyer's state)
- Incorrect SAC code or missing SAC on invoice
- Not issuing Receipt Voucher for advance/booking amounts
- Continuing to raise invoices after OC/CC is received
- Charging old rate (12%) for commercial projects post 22 Sept 2025
- Not generating e-Invoice for B2B buyers (if T/O > ₹5 crore)
e-Invoicing for Builders (Mandatory if T/O > ₹5 Crore): Builders with aggregate annual turnover exceeding ₹5 crore must generate all B2B invoices (to registered buyers / corporate buyers) through the Invoice Registration Portal (IRP). Each invoice must carry an IRN (Invoice Reference Number) and QR code. Non-compliance results in the invoice being treated as invalid — and the B2B buyer loses ITC. Refer: GST Invoice Format Guide.
GST Return Filing for Builders — FY 2026-27
Which GST returns builders must file, due dates, and compliance schedule for FY 2026-27.
GSTR-1 and GSTR-3B Filing Requirements
| Return | Purpose | Frequency | Due Date | Applicability |
|---|---|---|---|---|
| GSTR-1 | Outward supply invoice details — each unit sale invoice uploaded here | Monthly (T/O > ₹5 Cr) / Quarterly (QRMP) | 11th of next month / 13th of next quarter | All registered builders |
| GSTR-3B | Summary return + tax payment (incl. RCM on TDR/JDA/GTA) | Monthly or Quarterly (QRMP) | 20th / 22nd / 24th based on state | All registered builders |
| GSTR-9 | Annual consolidated return — reconcile project-wise sales and ITC | Annually | 31st December of next FY | T/O > ₹2 crore |
| GSTR-9C | Reconciliation statement — certified by CA/CMA | Annually | Along with GSTR-9 | T/O > ₹5 crore |
| ITC-04 | Goods sent to / received from job worker | Half-yearly | 25th of month after half-year end | Builders sending materials to contractors at job work |
QRMP Scheme for Builders: Builders with aggregate turnover up to ₹5 crore can opt for the QRMP scheme — file GSTR-1 and GSTR-3B quarterly while paying tax monthly via challan. This significantly reduces the return filing burden for small to mid-size builders. Learn more: QRMP Scheme — Complete Guide | GST Return Filing Services.
Project-wise Accounting is Critical: Builders with multiple ongoing projects (some residential, some commercial, some affordable housing) must maintain strict project-wise books of account. Each project may have a different GST rate, different ITC eligibility, and different TDR/JDA treatment. A single consolidated ledger will make GSTR-9 reconciliation extremely difficult and invite audit scrutiny.
Common GST Mistakes Made by Builders
Real-world GST errors made by builders and developers in India — with practical solutions.
-
1
Charging GST on full sale value without land deduction
Builders often charge GST on the full consideration (including land value) instead of restricting it to 2/3rd (construction component only). This results in excess GST collection from buyers — and excess tax liability to the government.
Apply the 1/3rd land deduction on all under-construction flat sale invoices. GST must be charged only on 2/3rd of the total consideration. Ensure your billing software is configured correctly from Day 1 of the project. -
2
Still charging 12% on commercial projects post September 2025
Builders with ongoing commercial projects launched before GST 2.0 are still raising invoices at 12% for payments received on or after 22 September 2025 — which is now incorrect and results in short-charging of GST.
Update all commercial project invoices to 18% for payments received on or after 22 September 2025. Issue supplementary invoices / debit notes for any short-charged amounts and deposit the differential GST with interest. -
3
Not paying RCM on TDR / JDA transactions
Many builders acquire TDR/FSI or enter JDAs without computing and paying 18% GST under RCM. This is a top audit trigger — the department scrutinizes TDR transactions specifically during assessments.
Calculate RCM liability on all TDR/FSI acquisitions at the time of purchase. Pay via GSTR-3B under the RCM head. Maintain all TDR purchase documents. Seek specialist JDA structuring advice post-Bombay HC 2025 ruling. -
4
Raising GST invoices after OC / CC is received
Some builders continue to raise GST-charged invoices for installments due/received after the Occupancy Certificate has been issued. This is incorrect — post-OC payments are exempt from GST entirely.
Track OC/CC receipt date for every project. From the date OC/CC is received, all subsequent payment demands and receipts must be without GST. Issue a revised invoice or a note to correct any erroneous GST charged post-OC. -
5
Claiming ITC on residential project inputs (5% scheme)
Builders under the 5% residential scheme attempt to claim ITC on cement, steel, and contractor invoices in GSTR-3B. This ITC is blocked under Section 17(5) and will be reversed during scrutiny with 18% interest.
Ensure your accounting team is aware that ALL construction input ITC is blocked for residential projects under the new rate scheme. Only office/admin expense ITC is claimable. Set up accounting controls to prevent erroneous ITC claims. -
6
No Receipt Voucher for booking amounts
Builders receive booking advances and construction-linked payments but do not issue Receipt Vouchers or declare GST on these collections in GSTR-3B — causing significant GSTR-1 vs. GSTR-3B mismatches and department scrutiny.
Issue a GST Receipt Voucher for every payment received (booking, milestone, demand). Declare GST liability in GSTR-3B for the period of collection. Adjust when final Tax Invoice is issued. Read: Treatment of Advance Received Under GST. -
7
Wrong Place of Supply on invoices (inter-state buyers)
When a buyer from another state purchases an under-construction flat, the Place of Supply is the location of the property — not the buyer's state (per Section 12(3) IGST Act). Charging CGST+SGST instead of IGST for such buyers is a legal error.
Always use the state where the project/property is located as the Place of Supply for construction services — regardless of the buyer's home state. Charge CGST+SGST if the buyer is from the same state; charge IGST if from a different state. Read: Place of Supply for Immovable Property.
Penalties for GST Non-Compliance by Builders
Financial and legal consequences of GST non-compliance for real estate builders and developers in FY 2026-27.
Late Filing — GSTR-1 / GSTR-3B
₹50 per day (₹25 CGST + ₹25 SGST) for returns with liability. Maximum ₹10,000 per return. Nil return: ₹20/day.
Interest on Late Tax Payment
18% per annum on unpaid GST from due date till actual payment. Section 50 CGST Act — applies automatically.
Wrong Rate / Short GST Charged
Demand under Section 73 (genuine error) — 10% penalty of tax + 18% interest. Under Section 74 (intentional) — 100% penalty.
Fraudulent / Excess ITC Claim
Claiming blocked ITC on residential projects or fraudulent ITC under Section 74 — full tax + 100% penalty + criminal risk above ₹5 crore.
Non-Payment of RCM (TDR / JDA)
10% of tax due for genuine omission; up to 100% if deliberate. TDR/JDA RCM non-payment is a top GST audit trigger for builders.
Non-Registration
10% of tax or ₹10,000 — whichever higher — for failure to register despite liability. Section 122 CGST Act.
Section 132 — Criminal Prosecution Risk: Builders involved in fraudulent ITC claims or tax evasion above ₹5 crore risk imprisonment up to 5 years under Section 132 of the CGST Act. For ₹2–5 crore — up to 3 years. This applies to managing directors, partners, and authorized signatories personally. Refer: GST Prosecution, Penalty & Procedure | GST Late Fees & Interest Guide.

Frequently Asked Questions — GST for Builders
Answers to the most commonly asked questions about GST for builders in India for FY 2026-27.
-
GST for builders refers to the Goods and Services Tax levied on the sale of under-construction properties. GST applies when a buyer purchases a flat, apartment, or commercial unit while construction is in progress — before the builder obtains an Occupancy Certificate (OC) or Completion Certificate (CC). For FY 2026-27, residential under-construction flats attract 5% GST (no ITC), affordable housing attracts 1% GST (no ITC), commercial under-construction units attract 18% GST (with ITC), and ready-to-move properties (post OC/CC) are exempt from GST entirely.
-
For FY 2026-27, the GST rate on under-construction flats is: 5% (without ITC) for non-affordable residential units, and 1% (without ITC) for affordable housing units (carpet area ≤ 60 sqm in metros / ≤ 90 sqm in other cities, value ≤ ₹45 lakh). These rates remain unchanged under GST 2.0 effective 22 September 2025. GST is calculated on 2/3rd of the total consideration (excluding 1/3rd deemed land value). No GST is applicable on payments received after the builder receives OC/CC.
-
No. GST is not applicable on ready-to-move properties. Once a builder has received an Occupancy Certificate (OC) or Completion Certificate (CC) from the competent authority, the sale is treated as a transfer of immovable property — not a supply of goods or services — and is completely exempt from GST. The buyer pays only Stamp Duty and Registration charges. This applies to both residential and commercial completed properties.
-
Affordable housing under PMAY criteria attracts 1% GST without ITC under Notification 3/2019-CT(R). Criteria: carpet area must be ≤ 60 sqm in Delhi NCR, Mumbai, Bengaluru, Chennai, Hyderabad, Kolkata (metro cities) or ≤ 90 sqm in all other cities, AND the gross consideration must not exceed ₹45 lakh. The builder cannot claim ITC on cement, steel, or contractor invoices for these projects. This rate is unchanged under GST 2.0.
-
It depends on the type of project. Builders under the 5% residential or 1% affordable housing scheme CANNOT claim ITC on construction inputs — cement, steel, contractor invoices are all blocked under Section 17(5)(c) and (d). However, builders developing commercial properties at 18% GST CAN claim full ITC on construction inputs, which offsets against the 18% GST charged to buyers. For mixed projects, ITC must be apportioned under Rule 42 of the CGST Rules.
-
JDA GST treatment is complex. Generally, when TDR/FSI is transferred by a landowner to a developer, 18% GST applies under RCM paid by the developer. The developer also pays GST (at 1%/5%/18% as applicable) on the units handed over to the landowner as consideration. However, the landmark Bombay High Court ruling (April 8, 2025) held that no GST applies if no TDR/FSI is actually transferred — merely granting the right to construct is not a taxable supply. Note: The Supreme Court stayed a related demand in October 2025 — this area remains under judicial consideration.
-
Under GST 2.0 effective 22 September 2025, commercial under-construction properties (offices, shops, commercial complexes) attract 18% GST with ITC. This is revised from the earlier 12% rate. The builder can claim ITC on all construction inputs for commercial projects. For payments received on or after 22 September 2025 for ongoing commercial projects, 18% GST applies — builders must update their billing and ensure they have revised all sale agreements and payment schedules accordingly.
-
Builders must file: GSTR-1 (by 11th monthly or 13th quarterly under QRMP) — upload all buyer invoices; GSTR-3B (by 20th monthly) — pay GST and declare RCM on TDR/JDA/GTA; GSTR-9 (annual by 31st December, T/O > ₹2 crore); GSTR-9C (reconciliation, T/O > ₹5 crore). Builders with T/O up to ₹5 crore can opt QRMP for quarterly filing. Project-wise accounting and GSTR-2B reconciliation is critical for multi-project builders.
