GST on House Purchase: Rates, Rules and How It Impacts Property Prices

GST on a house purchase depends on whether the property is under-construction, ready-to-move-in, or land. Under-construction homes attract 1% GST for affordable housing (up to ₹45 lakh, 60 sq m carpet area in metros) and 5% for non-affordable housing, both without input tax credit. Ready-to-move-in homes with a Completion Certificate, resale properties, and pure land purchases attract zero GST. Buying ready-to-move-in remains the most effective legal way to avoid GST entirely.

GST on house purchase is one of the biggest cost factors buyers overlook when budgeting for a new home. Since GST was introduced in July 2017, it has reshaped how residential property is taxed in India, folding VAT, service tax and excise duty into a single system. Whether you're a first-time homebuyer or a seasoned investor, understanding GST on residential property purchase is crucial, since the tax structure directly affects the final price you'll pay, from under-construction flats to ready-to-move-in homes. Here's what you need to know.

The Pre-GST Era: Why the Old Tax System Was Confusing

Before GST, Indian real estate ran on a patchwork of taxes that varied by state and project type, making it hard to predict costs:

• VAT (Value Added Tax): Applied to construction materials, at state-level rates that varied by region.
• Service Tax: Levied on the labour portion of under-construction property costs.
• Stamp Duty and Registration: State-imposed charges separate from the sale value, which still apply today.

GST replaced VAT and service tax with one consistent rate across the country, making pricing more transparent and predictable for both buyers and developers.

GST on Under-Construction vs Ready-to-Move-In Property

The single biggest factor in how much GST you pay is whether the property is under construction or already complete.

• Ready-to-move-in homes: Once a property has a Completion Certificate (CC) from local authorities, it's treated as a sale of immovable property, not a service — so no GST applies at all.
• Under-construction homes: These are treated as "works contract" services (construction is still in progress), so GST applies to both material and labour costs.

TIP: This is the single most effective way to reduce or fully avoid GST on a flat purchase — buying a ready-to-move-in home with a CC in hand means you pay zero GST on the property, though stamp duty and registration still apply. See our full comparison of under-construction vs ready-to-move-in homes for the trade-offs beyond just tax.

GST Rates on Residential Property Purchase

For under-construction properties, GST is charged based on whether the project qualifies as affordable or non-affordable housing:

Neither affordable nor non-affordable housing allows developers to claim ITC, which means the tax paid on materials and services during construction gets passed on to the buyer as part of the final price.

What Qualifies as Affordable Housing Under GST?

To qualify as affordable housing under GST, a property must meet both a price and a size test:

• Price: The unit must be priced up to ₹45 lakh.
• Carpet area: Up to 60 square metres in metro cities like Mumbai, Delhi and Bengaluru, or up to 90 square metres in non-metro cities like Mysuru, Jaipur and Pune.

A property that misses either limit is taxed as non-affordable housing at 5% GST. This is worth flagging clearly: Brigade Group's residential projects across Bengaluru, Chennai and Hyderabad are premium developments, so they fall under the non-affordable, 5% GST category rather than the 1% affordable slab.

Understanding Input Tax Credit (ITC) on Residential Property

Input Tax Credit (ITC) normally lets businesses claim back GST paid on inputs, reducing the cascading effect of tax on tax. For residential property, though, ITC isn't available to developers on under-construction projects. This means:

• Developers pay GST on construction materials and services but can't offset it.
• That cost gets built into the price you pay as a buyer.
• The GST rate you see (1% or 5%) is effectively the final rate, since there's no credit reducing it further.

A Practical Example: Calculating GST on a Residential Property

• Affordable Housing Example: A unit in Pune priced at ₹30,00,000, taxed at 1% GST, works out to ₹30,000 in GST, for a total of ₹30,30,000.
• Non-Affordable Housing Example: A unit priced at ₹60,00,000, taxed at 5% GST, works out to ₹3,00,000 in GST, for a total of ₹63,00,000.

As the numbers show, GST on non-affordable housing has a much bigger impact on your total cost, both in rupee terms and as a share of the price.

How to Legally Reduce GST on Flat Purchase

There's no way to legally dodge GST that's genuinely due, but there are legitimate ways to lower what you pay:

• Buy ready-to-move-in: Homes with a Completion Certificate attract zero GST, so this is the most effective way to avoid the tax entirely.
• Check the affordable housing criteria: If your budget and preferred carpet area fall within the ₹45 lakh price cap and size limits, you'll pay 1% instead of 5%.
• Negotiate the payment schedule: Where possible, paying a larger share after possession (once the CC is issued) reduces the portion of your payment that attracts GST.
• Watch for preferential location charges (PLC): Premiums for a park-facing unit, higher floor or corner plot attract GST at the same rate as the base property price, so factor this into your budget rather than treating it as a separate cost.
• Be cautious of any developer suggesting informal, off-the-books payments to avoid GST — this isn't a legal workaround and can create serious problems with title and documentation later.

GST 2.0 and Recent Changes

GST rates on real estate are reviewed periodically, and construction material costs shifted under the GST 2.0 revisions rolled out in September 2025. These changes mainly affect developer input costs (cement, tiles, sand and other materials) rather than the 1%/5% rate buyers pay directly. For a deeper look at how GST 2.0 is affecting construction costs and project pricing, see our blog on how the new GST cuts impact real estate this year.

Conclusion

Understanding GST on house purchase is essential for any buyer navigating today's real estate market. Ready-to-move-in properties are exempt from GST entirely, while under-construction properties attract 1% or 5% GST depending on whether they qualify as affordable housing, with no Input Tax Credit available to soften the cost either way. If you're still deciding between an under-construction and a completed home, our detailed comparison of under-construction vs ready-to-move-in homes covers the trade-offs beyond just tax. Whether you're buying a first home or a luxury flat, factoring in GST early helps you budget accurately and avoid surprises at the time of payment.

FAQ

1. Is GST applicable to resale properties?

No. GST only applies to under-construction properties. Resale and ready-to-move-in properties with a Completion Certificate are exempt.

2. Who should pay GST, the builder or the buyer?

The builder collects GST from the buyer as part of the property price and deposits it with the government. While the developer is legally responsible for remitting the tax, the cost is passed on to the buyer in the sale price.

3. What will the GST rate on real estate be in 2026?

As of now, the rates remain 1% for affordable housing and 5% for non-affordable housing on under-construction properties, both without Input Tax Credit. GST 2.0 changes in 2025 affected construction material rates rather than these buyer-facing property rates, though it's worth checking for updates before you finalise a purchase.

4. How can I avoid or reduce GST on a flat purchase?

The most effective legal way is to buy a ready-to-move-in property with a Completion Certificate, which attracts zero GST. If you're buying under construction, check whether the property qualifies for the 1% affordable housing rate instead of the 5% non-affordable rate.

5. Can I get a refund for GST paid on an under-construction flat?

No, GST refunds aren't available on under-construction flat purchases. However, buyers can discuss with the builder whether any input cost savings can be passed on as a price reduction.

6. How do I know if my property qualifies as 'affordable housing' for GST?

Check both the price (up to ₹45 lakh) and the carpet area limit — 60 square metres in metro cities, 90 square metres in non-metro cities. Both conditions must be met for the 1% rate to apply.

7. Does GST apply to the purchase of a plot of land?

No. GST does not apply to the purchase of pure land, since it isn't considered a construction service. It only applies to the construction of a building or property.

8. What else should I budget for apart from GST when buying a residential property?

Alongside GST, factor in stamp duty and registration charges, maintenance costs, and any preferential location charges. GST also applies at 18% on maintenance charges once a residential welfare association's collections cross the prescribed threshold.
