K-RERA Orders Casagrande Garden City to Refund Rs 52.74 Lakh on GST: The January 2026 Precedent and What Bengaluru Buyers Should Check on Their Own Cost Sheets

On January 2, 2026, K-RERA passed an order directing Casagrande Garden City Builders Pvt Ltd to refund Rs 52.74 lakh to a Bengaluru homebuyer after finding that the developer engaged in unfair trade practices related to GST billing. The bench, headed by Member GR Reddy, observed that the builder repeatedly altered the cost breakup of the property and inflated the GST component, resulting in an undue financial burden on the buyer. The order is one of the cleanest recent precedents on developer GST treatment of under-construction properties in Bengaluru and has implications for buyers across the city whose cost sheets show similar patterns. This piece walks through the order, the underlying GST framework for under-construction residential property, and the concrete buyer-side cost sheet checks that can flag unfair GST billing before the transaction closes.

What exactly did the K-RERA Casagrande Garden City order say?

The order, dated January 2, 2026 and issued by Member GR Reddy, found that the developer had engaged in three specific unfair trade practices. First, the cost breakup of the property was repeatedly altered between booking, agreement, and final billing, with different splits between basic cost, parking, club, and other charges across iterations. Second, the GST component was inflated beyond the statutorily applicable rate on the relevant cost components. Third, the developer failed to provide a transparent computation of the GST liability with reference to the underlying GST framework when the buyer requested clarification. K-RERA found these practices to be unfair trade practices within the meaning of relevant RERA provisions and directed the refund of Rs 52.74 lakh, which represents the excess GST and miscalculated charges paid by the buyer. The order is appealable to the Karnataka RERA Appellate Tribunal, but the substantive findings establish a usable precedent for similar buyer disputes.

What is the GST framework for under-construction residential property?

The GST regime distinguishes between under-construction property (where construction is incomplete at the time of purchase) and ready property with Occupancy Certificate (where construction is complete and OC is issued). For under-construction residential property, the applicable GST rate depends on the project category. Affordable housing projects (specific criteria on price and carpet area) attract 1 percent GST without input tax credit (ITC). Other residential projects attract 5 percent GST without ITC. Commercial and mixed-use components attract 12 percent GST with ITC. For ready property with OC issued before the transaction, no GST applies; only stamp duty and registration. The applicable GST is computed on the basic cost of the property plus certain integral components (parking, club, common area maintenance corpus) but excludes certain items (separate registration of car park, post-OC AMC, society maintenance pre-payment). Our Karnataka stamp duty piece covers the parallel stamp duty framework.

What are the most common unfair GST billing patterns?

Four patterns flagged across multiple K-RERA and consumer forum complaints. First, applying 12 percent commercial GST rate on residential cost components by mis-categorising the project or specific charges. Second, applying GST on items that should be GST-exempt such as registration charges, stamp duty, and pre-OC society membership fees. Third, applying GST on the gross value including the land cost component, when GST applies only to the construction and integral services value (typically the construction component is 2/3 of the under-construction property value, with land at 1/3 deemed exempt). Fourth, applying multiple layers of GST on the same component (for example, GST on the basic cost plus a separate GST line on the development charges that are already embedded in basic cost). The Casagrande Garden City order specifically addressed cost-breakup manipulation and inflation, which combines two or more of these patterns. Buyers should treat any cost sheet with iteration-by-iteration breakup changes as a structural warning sign requiring detailed scrutiny.

What buyer-side cost sheet checks catch these issues?

Six concrete checks. First, verify the project's GST category (affordable at 1 percent or other residential at 5 percent) by cross-referencing the RERA registration document and the builder's GST registration. Second, confirm that GST is computed on the construction value (typically 2/3 of property cost), not the gross property value including land. Third, ensure no GST is being charged on registration fees, stamp duty, or items that are statutorily exempt. Fourth, demand a transparent computation memo showing the GST base, the rate applied, and the final GST amount for each cost component. Fifth, retain all cost sheet iterations and the booking-to-agreement-to-billing breakup; iteration-by-iteration changes are themselves a warning sign. Sixth, request the developer's GST return filings (GSTR-3B and annual return) for the project to confirm the GST collected from buyers matches what is deposited with the government. The Casagrande Garden City buyer ultimately succeeded because they retained iteration documentation and could demonstrate the inflated billing pattern. Our cement and steel input cost piece covers the related construction cost framework.

What is the role of Input Tax Credit (ITC) in the residential GST framework?

Under the current GST framework for residential property (1 percent affordable and 5 percent other), the developer does not get Input Tax Credit on the construction inputs (cement, steel, finishings). The GST charged to the buyer at 1 percent or 5 percent is the final tax incidence, with no setoff against the GST that the developer paid on inputs. This is materially different from the pre-April 2019 framework, where developers could claim ITC and pass through different rates. The buyer-side implication is that the GST liability is fixed at 1 percent or 5 percent depending on project category, and any developer claim that ITC complicates the math or justifies a different rate is structurally incorrect under the current framework. The Casagrande Garden City order partially leveraged this clarity to flag the GST inflation as unfair trade practice. Buyers should be sceptical of any developer pitch that invokes ITC ambiguity to justify higher GST charges on residential under-construction property.

How can buyers actually use the Casagrande precedent for their own disputes?

Three operational steps. First, compile a complete documentation set: original booking agreement, all cost sheets received during the transaction, final billing breakup at handover, GST invoices issued by the developer, and any email or letter correspondence on cost breakup changes. Second, prepare a written demand letter to the developer specifically referencing the GST framework (1 percent or 5 percent rate, computation on construction value only) and requesting a transparent computation memo. Send the letter by registered post with acknowledgment due. Third, if the developer does not respond within 30 days or refuses to refund the excess GST, file a complaint with K-RERA (or the relevant state RERA) specifically citing the Casagrande Garden City order as precedent for unfair trade practice. The complaint should be filed under the unfair trade practice provisions and include the demand for refund with interest at SBI MCLR plus 2 percent. K-RERA complaints are filed online with a nominal fee. Our Supreme Court paper tiger piece covers the broader enforcement context within which this precedent operates.

What about projects where OC is already issued?

For projects where the developer has obtained Occupancy Certificate before the buyer's transaction (typically resale ready inventory or end-of-cycle direct sale), no GST applies on the property sale itself. Only stamp duty and registration apply. Buyers transacting on OC-issued properties should not be charged any GST by the developer or the seller; any GST charge on such transactions is structurally incorrect. The exception is if the developer is selling services or amenities separately (interior fit-out, premium AMC packages) that are themselves taxable services; these can attract GST but only at the applicable services rate (typically 18 percent) and only on the genuine service value. The Casagrande Garden City order did not directly address OC-issued projects, but the principle of transparent cost breakup applies equally. Buyers on OC-issued properties should explicitly verify that no GST is being charged on the property sale itself and only on legitimate separately-billed services.

What is the broader signal from this order for Bengaluru buyers?

K-RERA's willingness to apply unfair trade practice provisions to GST billing irregularities is a meaningful expansion of buyer protection beyond the traditional possession-delay and refund disputes. The Casagrande Garden City order joins the Mantri Developers 5 percent penalty order from earlier in May 2026 as part of a sharpened K-RERA enforcement posture through 2026. Buyers should read this as positive signal that K-RERA is increasingly willing to scrutinise developer practices beyond the headline procedural compliances. The practical implication is that buyers facing similar cost-sheet manipulation, GST inflation, or fee-stacking practices now have a cleaner precedent path to pursue refund through K-RERA. The downside, consistent with the broader Supreme Court observation, is that K-RERA enforcement of refund orders remains slow even where the order is favourable. Buyers should still treat this as a remedial backstop rather than a primary risk management. Our Mantri Developers K-RERA piece covers the parallel enforcement signal.

What is the single most useful buyer takeaway from this precedent?

Retain every cost sheet iteration and demand a transparent GST computation memo before paying beyond a token amount. The single discipline of retaining iteration documentation is what enabled the Casagrande Garden City buyer to succeed at K-RERA. Buyers who casually accept the final billing without comparing it against earlier iterations have materially weaker positions in disputes. For new purchases in May 2026, the demand for a clean GST computation memo (rate applied, computation base, final amount per component) should be a non-negotiable condition before signing the sale agreement. Developers who refuse this transparency check are themselves a warning signal. Buyers who insist on this discipline at the point of purchase rarely need to litigate later; the documentation discipline itself often deters the unfair-billing practices the Casagrande order targeted.

The K-RERA Casagrande Garden City order of January 2, 2026 is a usable precedent for Bengaluru buyers facing similar GST billing irregularities. The Rs 52.74 lakh refund directive establishes that cost-breakup manipulation and GST inflation constitute unfair trade practice subject to remedy under RERA. Buyers should treat this as a signal both to scrutinise their own cost sheets rigorously and to pursue remedy through K-RERA if irregularities are identified. The underlying GST framework for under-construction residential property (1 percent affordable, 5 percent other, computed on construction value only) is well-defined; developer attempts to inflate beyond this framework are structurally challengeable. The single discipline of retaining cost-sheet iteration documentation and demanding transparent computation memos is the most valuable buyer-side defence. The Casagrande precedent is one of several signals that K-RERA's enforcement posture is sharpening through 2026.
