GST on Real Estate Industry

GST on Real Estate Industry

The short answer for FY 2026-27: GST on real estate divides into four rate bands — 1%, 5%, 12%, and nil — determined by project type, affordability criteria, and whether a completion certificate has been issued. The 80% procurement rule, reverse charge on cement, JDA development-rights RCM triggered at completion, and conditional TDR exemption layer on top. Classify your project correctly before you price a single unit; every subsequent compliance decision flows from that classification, and getting it wrong hands the department a ready-made demand notice.

The Four-Rate Matrix: Where Your Project Sits

The post-April 2019 rate structure — retained intact by Union Budget 2026 — applies to all residential and commercial real estate projects. Four bands cover every scenario:

The first classification call you must make is RREP vs REP. A Residential Real Estate Project (RREP) is one where the commercial component does not exceed 15% of total carpet area. A Real Estate Project (REP) contains commercial space exceeding that 15% threshold. In an RREP, even the commercial units are taxed at 5% without ITC. In a REP, the residential portion stays at 1%/5%, but the commercial portion moves to 12% with full ITC — requiring strict project-level accounting to separate the two pools.

Defining "Affordable Housing" with Precision

The 1% rate is available only where both conditions are satisfied simultaneously:

1. Carpet area does not exceed 60 sqm in metropolitan cities (Delhi NCR, Mumbai MMR, Chennai, Kolkata, Bengaluru, Hyderabad) or 90 sqm in all other cities and towns.
2. Gross consideration does not exceed Rs. 45 lakh (all-inclusive, before GST).

A flat in Coimbatore with an 88 sqm carpet area priced at Rs. 40 lakh is not affordable — it fails the area test even though it clears the price gate. Both conditions must be met.

RERA carpet area ≠ popular usage. The GST definition of carpet area follows Section 2(k) of the Real Estate (Regulation and Development) Act, 2016, which excludes external walls, service shafts, exclusive balconies, verandahs, and open terraces. Builders who inadvertently include these areas inflate the carpet area figure, causing an affordable unit to misclassify as non-affordable and attracting a 4-percentage-point rate differential. Cross-check your RERA carpet area certificate against the statutory definition before applying the 1% rate.

The 80% Procurement Rule: Mechanics and Arithmetic

The 1% and 5% rates are conditional on procuring at least 80% of inputs and input services from GST-registered suppliers. This is a project-level, cumulative test — not a monthly hurdle. The shortfall attracts reverse charge at 18%, payable in cash with no ITC offset.

The Cement Exception: RCM at 28%, Always

Cement purchased from an unregistered supplier attracts RCM at 28% in the period of purchase — regardless of whether the 80% threshold has already been met for the project overall. This is a hard rule with no exceptions. It applies to all grades: OPC, PPC, PSC, and white cement.

Worked Example: Quantifying the Procurement RCM Exposure

Non-affordable residential project, Nagpur (non-metro), FY 2026-27.

Step 1 — Cement RCM (automatic, no threshold test needed): Rs. 30,00,000 × 28% = Rs. 8,40,000, payable in Table 3.1(d) of GSTR-3B for the month of purchase.

Step 2 — Test the 80% threshold (excluding cement from unregistered): Adjusted total procurement = Rs. 4,00,00,000 − Rs. 30,00,000 = Rs. 3,70,00,000 80% target = Rs. 3,70,00,000 × 80% = Rs. 2,96,00,000 Registered procurement = Rs. 2,80,00,000 Shortfall = Rs. 2,96,00,000 − Rs. 2,80,00,000 = Rs. 16,00,000

Step 3 — Shortfall RCM: Rs. 16,00,000 × 18% = Rs. 2,88,000, payable in cash.

Total additional GST cash outflow: Rs. 11,28,000 — with zero ITC available to absorb it.

On a Rs. 4 crore procurement base, the difference between 79% and 80% registered procurement is roughly Rs. 3 lakh in extra cash tax. On a Rs. 40 crore project, it crosses Rs. 30 lakh. Procurement planning is not a compliance afterthought — build registered-vendor targets into your subcontractor award criteria from the tender stage.

Joint Development Agreements: When GST Triggers and Who Pays

JDAs are the most litigated area in real estate GST. The framework rests on Notification No. 4/2018-CT(R) and Circular No. 151/07/2021-GST.

Two Supplies, Two Tax Events

Supply 1 — Development rights transferred by landowner to developer: This is a supply of service by the landowner. The developer pays GST on it under reverse charge, but only on the date of issuance of the completion certificate (CC), or date of first occupation, whichever is earlier. The time-of-supply deferral to CC date is deliberate — the developer has no cash flow from the project until flats are sold.

Supply 2 — Construction service provided by developer to landowner: When the developer allots constructed flats to the landowner as part of the JDA consideration, this is a taxable construction service at 1%, 5%, or 12% depending on project category.

Valuing the RCM on Development Rights

Circular 151/07/2021-GST provides the valuation framework. For the portion of flats unsold at the CC date, the value of development rights equals the proportionate construction cost attributable to those flats.

Worked JDA Example

Project: 40 flats, non-affordable RREP, Bengaluru. Developer–landowner split: 70% (28 flats) to developer, 30% (12 flats) to landowner. Total construction cost: Rs. 5,00,00,000. At CC date — 8 of the 12 landowner flats and 28 of the developer's 28 flats have been sold. 4 landowner flats remain unsold.

Proportionate construction cost for 4 unsold flats: 4 / 40 × Rs. 5,00,00,000 = Rs. 50,00,000

Developer's RCM on development rights for unsold 4 flats (payable on CC date): Rs. 50,00,000 × 18% = Rs. 9,00,000

For the 8 landowner flats sold before CC, GST on the construction service at 5% was already payable at the time of each sale. That liability pre-exists and is forward charge on the developer. The RCM obligation at CC covers only the unsold residual.

Income Tax note: Under Section 194-IC of the Income Tax Act, 1961, TDS at 10% applies to any monetary payment made by a developer to a landowner under a JDA. Cross-check TDS obligations alongside GST at JDA commencement — both run concurrently.

TDR, FSI and Long-Term Lease Premiums

Transferable Development Rights (TDR) and Floor Space Index (FSI) are treated as taxable services at 18%. The key exemption and RCM rules under Notification No. 4/2019-CT(R) are:

• Exempt: TDR/FSI used for residential construction, to the extent of flats sold before the CC date. Long-term lease premiums (30+ years) on plots granted by Government and notified industrial development authorities for residential construction are also exempt.
• Taxable under RCM at 18%: TDR/FSI attributable to residential flats unsold at CC date, paid by the developer. TDR/FSI used for commercial construction carries no exemption and is taxable at 18% RCM regardless.

Tracking your sales register relative to the CC date is therefore a tax management exercise, not just a RERA disclosure obligation. A last-minute burst of bookings before the CC date reduces your TDR RCM exposure directly.

Time of Supply and Invoice Discipline

GST liability on construction services arises under Section 13 of the CGST Act, 1961 at the earlier of:

• Date of invoice, or
• Date of receipt of payment

Developers typically issue demand notices tied to construction milestones. A demand notice alone is not a tax invoice under GST. A formal tax invoice must be raised on or before the date of receipt of payment or within 30 days of service completion — whichever is earlier. Issuing demand notices without corresponding tax invoices creates a mismatch between GSTR-1 and bank receipts, which the system flags in scrutiny.

HSN code for residential construction services: 9954 12 (SAC 995411 — construction of residential buildings). Use this consistently across GSTR-1, e-invoices (mandatory where aggregate turnover exceeds Rs. 5 crore in the preceding financial year), and all contractual documentation.

RERA alignment: Every invoice and demand letter must separately state the GST amount, the applicable rate, and whether ITC is available or not. Inconsistency between your GSTR-1 filings and RERA project account statements is a red flag in both RERA audits and GST scrutiny proceedings. Auditors routinely compare both sets of records.

Brokerage, RWA Maintenance and Renting: The Allied Transactions

Real Estate Brokerage and Commission

A broker or agent arranging the sale, purchase, or rental of property owes 18% GST with ITC under SAC 997233. The service is taxable regardless of whether the underlying property transaction falls inside or outside the GST net. Brokers must issue tax invoices; if registered under the composition scheme, they may not charge GST separately.

Resident Welfare Association Maintenance Charges

• Up to Rs. 7,500 per member per month — exempt, regardless of the RWA's aggregate turnover.
• Above Rs. 7,500 per member per month — 18% GST on the entire monthly charge, not just the excess.

This is the most commonly misread exemption in residential GST. If an RWA charges Rs. 8,500 per month, the full Rs. 8,500 is taxable at 18% — the Rs. 7,500 is an eligibility threshold, not an exemption limit. If the member owns two flats in the same complex, each flat's maintenance charge is assessed separately against the Rs. 7,500 threshold.

Renting of Immovable Property

The RCM on residential rentals to registered persons (effective 18 July 2022 under Notification 05/2022-CT(R)) catches every company that leases residential flats for employee accommodation. If you are a registered entity renting a residential flat — even for an individual employee's use — you owe 18% GST under RCM in your GSTR-3B, regardless of whether your landlord is registered or not. Many corporates discovered this liability during scrutiny years later, along with accumulated interest at 18% per annum under Section 50 of the CGST Act.

Resale of Completed Property

Once a completion certificate is issued or the property has been first occupied, any subsequent sale is a transfer of immovable property — entirely outside the GST net. Stamp duty and registration charges apply. No GST invoice is required, and no GST liability arises — whether the seller is a builder with unsold inventory or an individual reselling a flat purchased years earlier.

ITC Reversal Under Rules 42 and 43

Developers operating under the 1%/5% no-ITC regime are barred from claiming input tax credit on all project-related inputs, input services, and capital goods. Where the same entity also undertakes taxable commercial construction (12% with ITC), it must apportion ITC under the CGST Rules.

Rule 42 applies to inputs and input services used partly for taxable and partly for exempt or no-ITC supplies:

> ITC to be reversed = (Common ITC) × (Value of exempt/no-ITC supplies ÷ Total turnover in the period)

Rule 43 applies to capital goods — cranes, batching plants, transit mixers — used across mixed projects. The reversal runs over 60 months at 1/60th per month.

Exempt supplies for Rule 42 purposes include sale of completed flats (post-CC), interest income from delayed buyer payments, and any other non-taxable income generated by the entity. These are commonly overlooked, which is why Rule 42 demands in real estate audit proceedings are almost always larger than the developer expects.

Maintain a project-specific ITC ledger from Day 1. Commingling residential and commercial cost centres in your accounting system is the single biggest cause of Rule 42 demands in practice.

Common Mistakes and Pitfalls to Avoid

1. Misclassifying RREP vs REP at project planning stage. A project with shops on the ground floor that account for 16% of total carpet area is a REP, not an RREP. Once sold at 5%, correcting the rate upward triggers buyer renegotiation, refund requests, and potential RERA complaints. Compute the commercial-to-total carpet ratio before you launch.

2. Paying cement RCM at year-end instead of in the purchase month. RCM under Section 9(4) of the CGST Act (for cement from unregistered dealers) is due in the return period of purchase. A developer who stockpiles unregistered cement for 6 months and pays RCM annually owes interest at 18% per annum on each delayed payment from the GSTR-3B due date.

3. Treating the JDA signing date as the GST trigger date. RCM on development rights is triggered on the date of the CC, not when the JDA is signed or when excavation begins. Early payment is permissible but creates a cash-flow drag. Missing the CC-date trigger creates an interest exposure.

4. Applying the Rs. 7,500 RWA exemption as a slab deduction. Once a member's monthly charge exceeds Rs. 7,500, GST applies to the full amount — not just the excess. The threshold determines taxability, not quantum of exempt income.

5. Overlooking RCM on residential rentals paid by the company. HR and finance teams routinely miss this. Every residential lease taken by a registered entity triggers 18% RCM on the full rent, in every monthly GSTR-3B. The landlord's registration status is irrelevant.

6. Failing to maintain a transition workpaper for anti-profiteering. Anti-profiteering proceedings under Section 171 of the CGST Act, adjudicated by the Competition Commission of India (which absorbed the National Anti-Profiteering Authority), continue to arise for projects that straddled the April 2019 regime change. If your project collected 12% with ITC before April 2019 and shifted to 5% without ITC after, you need a documented working showing the net benefit passed on to buyers. Without it, even legitimate price increases attributable to steel and cement inflation can be characterised as profiteering.

Step-by-Step Launch Checklist for a New Residential Project

Build this structure before you sell the first unit:

1. Determine project category — compute carpet areas, confirm affordable/non-affordable split, calculate commercial-to-total carpet ratio to confirm RREP or REP status.
2. Register under RERA — the registration number is mandatory on every GST invoice.
3. Open a project-specific cost centre in your ERP — separate ledgers for ITC-eligible (commercial) and non-ITC (residential) procurement, from Day 1.
4. Set up a procurement register — capture each vendor's GSTIN, invoice date, supply value, and whether the vendor is registered or unregistered. Flag cement purchases as a separate line item.
5. Build an 80% registered-procurement alert — set an internal threshold at 85% to give yourself a safety buffer. Your procurement team must know that issuing a purchase order to an unregistered vendor for anything other than cement has a blended 18% RCM cost attached.
6. Issue milestone-linked tax invoices — each invoice carries the RERA registration number, SAC 995411, applicable GST rate, ITC status (not available), the buyer's PAN, and HSN-level GST breakup.
7. File GSTR-1 and GSTR-3B monthly — disclose all RCM liabilities (cement, shortfall, JDA development rights when triggered) in Table 3.1(d) and discharge in cash.
8. Run Rule 42/43 calculations quarterly — essential if you have common costs across RREP and commercial projects.
9. At CC issuance — compute and pay JDA development-rights RCM and TDR RCM on the unsold-inventory fraction before filing the return for that month.
10. Archive the full project file — invoices, procurement register, RCM workings, Rule 42/43 calculations, anti-profiteering workpaper, and RERA filings — for at least six years after the CC date, as required under Section 36 of the CGST Act.

Key Takeaways

• Four rate bands determine everything: 1% (affordable residential), 5% (non-affordable residential and commercial within RREP), 12% (standalone commercial and commercial portion of REP), nil (post-CC resale). Classify before you price.
• Both gates must open for 1%: carpet area ≤ 60/90 sqm and gross consideration ≤ Rs. 45 lakh. One failure pushes the rate to 5%.
• The 80% procurement rule is cumulative and project-level. Shortfall on non-cement items attracts 18% RCM in cash. Cement from unregistered suppliers always attracts 28% RCM, independently and in the month of purchase.
• JDA development-rights RCM is triggered on the CC date, not the signing date. Value it on proportionate construction cost for unsold flats at that date.
• TDR and FSI exemption is partial — exempt only for residential flats sold before CC; the unsold residential fraction and all commercial TDR attract 18% RCM.
• RWA maintenance above Rs. 7,500 per member per month attracts 18% GST on the full amount — the threshold is binary, not a slab.
• Project-wise cost centres, procurement registers, and Rule 42 workings must start on Day 1 — retroactive reconstruction ahead of audit is unreliable and exposes you to demands that the underlying facts would have defeated.
