GST on Under-Construction Property in India: The Complete Guide

Goods and Services Tax is one of the most misunderstood costs in an Indian property purchase — partly because it applies to some homes and not others, and partly because it sits on top of stamp duty rather than replacing it. Getting GST right matters, because on an under-construction home it can add a meaningful percentage to your total outlay, and it is the single biggest reason a ready-to-move home can end up costing less than it first appears versus an under-construction one at a similar sticker price.

This guide explains exactly when GST applies to residential property, the concessional rates for affordable and non-affordable homes, what "affordable housing" means for GST, why there is no input-tax-credit benefit under the current scheme, what GST does and does not cover, and how it factors into your buying decision. GST rates and definitions can change, so treat the figures here as the prevailing scheme and confirm the current rate for your specific purchase.

The quick answer: when does GST apply?

• GST applies to under-construction residential property — homes bought before the building receives its occupancy certificate.
• GST does not apply to a completed property with an occupancy certificate (OC), nor to resale property. These attract only stamp duty and registration.

The dividing line is the occupancy certificate. Once a project has its OC, a sale of that home is treated as a sale of immovable property, outside GST. Before the OC, you are effectively paying for a construction service, which is why GST applies.

The GST rates on residential property

Under the current concessional scheme, residential under-construction property is taxed at two main rates depending on whether it qualifies as affordable housing:

• Affordable housing: a lower concessional GST rate (commonly cited as 1%), without input tax credit.
• Non-affordable (other) housing: a higher rate (commonly cited as 5%), without input tax credit.

These rates apply to the value of the under-construction home (with the land portion accounted for through an abatement built into the scheme). Because rates and the scheme's mechanics can be revised, confirm the current applicable rate for your project before you budget.

What counts as "affordable housing" for GST?

The concessional affordable-housing rate is not a marketing label — it has a definition based on carpet area and price. Broadly, a home may qualify as affordable if its carpet area is within a defined limit (with different limits for metro and non-metro cities) and its value is within a defined price cap. If either threshold is exceeded, the home falls into the non-affordable category and the higher GST rate applies. Because these thresholds are specific and can change, confirm whether your particular home qualifies rather than assuming — the difference in rate is significant.

Why there is no input tax credit

Under the current concessional scheme, the lower GST rates come without input tax credit (ITC) — meaning the developer cannot pass through the GST they paid on inputs (cement, steel, services) to reduce your bill. In practical terms, the rate you see is broadly the rate you pay; there is no further ITC benefit to expect. This is a deliberate design of the concessional scheme, trading a lower headline rate for the removal of ITC.

GST is separate from stamp duty

A frequent point of confusion: GST and stamp duty are two different charges, and on an under-construction home you pay both. Stamp duty and registration are state charges on the transfer of the property; GST is a central tax on the construction. They are calculated separately, on their own bases, and neither replaces the other. When you total the cost of an under-construction home, include the price, GST, stamp duty, and registration — plus any GST on associated charges (below).

GST on other charges

Beyond the base price, developers often levy additional charges, and some of these can attract GST:

• Preferential location charges (PLC), floor-rise, and parking that are part of the composite supply of the under-construction home generally follow the home's GST treatment.
• Certain one-time deposits and maintenance-related amounts may have their own GST treatment depending on how they are structured.

Ask the developer for a clear cost sheet that shows the base price, each additional charge, and the GST on each, so you can see the true all-in cost rather than a headline figure that omits taxes and extras.

How GST affects the ready-vs-under-construction decision

GST is often the deciding financial factor between a ready and an under-construction home. Consider two homes at a similar sticker price — one ready with an OC, one under-construction. The ready home attracts no GST; the under-construction one adds GST on top. That difference can materially change which is cheaper on an all-in basis. This does not mean ready is always better — under-construction offers a lower entry price, staged payments, and appreciation potential — but it does mean you must compare on the GST-inclusive total, not the headline price, to make a fair decision.

A simple worked approach

1. Confirm whether the home is under-construction (no OC yet) — if it has an OC or is a resale, there is no GST.
2. Determine whether it qualifies as affordable (carpet-area and price thresholds) to know which rate applies.
3. Apply the current GST rate to the applicable value to estimate the GST.
4. Add stamp duty and registration separately.
5. Add GST on any additional charges from the cost sheet.
6. Compare this all-in total against a ready/resale alternative, which carries no GST.

Common GST questions and pitfalls

• "The flat is ready, do I pay GST?" If it has an occupancy certificate, no — only stamp duty and registration.
• "Is resale subject to GST?" No. Resale of a completed home is a sale of immovable property, outside GST.
• "Does GST replace stamp duty?" No. Both apply to an under-construction purchase.
• "Will I get input tax credit?" Not under the concessional scheme — the lower rate comes without ITC.
• "Is the rate the same for every flat?" No — affordable and non-affordable homes are taxed differently, based on carpet-area and price thresholds.

Your GST checklist

• Confirmed whether the home is under-construction or has an OC (GST applies only to the former).
• Checked whether it qualifies as affordable housing for the concessional rate.
• Applied the current GST rate to estimate the tax.
• Added stamp duty and registration separately.
• Reviewed the developer's cost sheet for GST on additional charges.
• Compared the GST-inclusive all-in cost against a ready/resale option.

The bottom line

GST applies to under-construction homes and not to completed or resale ones, sits alongside (not instead of) stamp duty, and comes without input tax credit under the current concessional scheme. For buyers, the practical takeaway is simple but important: always compare homes on the GST-inclusive, all-in cost. A ready home's higher sticker price may be closer to — or lower than — an under-construction home once GST is added. Know the rate that applies to your purchase, confirm whether it qualifies as affordable, and budget for GST from the start so it never becomes a closing-day surprise.

How GST on property has changed

It helps to understand the history, because you may encounter older figures. Before the 2019 rationalisation, under-construction homes were taxed at a higher headline GST rate with input tax credit, which developers were meant to pass on. In practice, the ITC pass-through was inconsistent and contentious. The current concessional scheme replaced that with lower rates and no ITC — simpler and lower-headline for buyers, but without any further credit to expect. If you see references to older, higher rates with ITC, they reflect the previous regime, not the current one; always use the current scheme for your purchase.

GST on plots and land

Buying a plot of land (without construction) is treated as a sale of immovable property and is outside GST — you pay stamp duty and registration, not GST. Where a transaction bundles land with a construction/development service, the construction element can attract GST, so the structure of the deal matters. For a straightforward plot purchase, expect no GST; for a plot-plus-construction package, clarify how the construction portion is taxed.

GST on renting a home

For most people renting a residential property to live in, GST does not apply to the rent. GST treatment can differ where residential property is rented to a registered business, or for commercial leasing, which follow their own rules. If you are an individual renting a flat as your home, GST is generally not a concern; if you are a business or landlord dealing with commercial or business-linked leasing, confirm the current position.

GST on commercial property

The framework extends to commercial property, but the treatment and rates differ from residential. Under-construction commercial units generally attract GST (often at a different rate and with different ITC rules than residential), while completed commercial property with the relevant certification is outside GST as a sale of immovable property. If you are buying commercial space, get the GST position confirmed specifically, as it does not mirror the residential concessional scheme.

GST for NRI buyers

GST on an under-construction home is the same whether the buyer is a resident or an NRI — it is a tax on the construction, not on the buyer's residency. So an NRI buying under-construction pays GST just as a resident would, on top of stamp duty and registration. For NRIs comparing options, the GST-free nature of ready and resale homes is an added reason many favour completed property for a first, remotely-managed purchase. GST does not affect repatriation directly, but it is part of your total acquisition cost, so keep the records.

How to spot GST being charged incorrectly

• GST on a ready/OC-received flat: should not be charged — if a seller adds GST to a completed home with an OC, question it.
• GST on resale: should not apply — a resale of a completed home is outside GST.
• The wrong rate: an affordable home charged at the non-affordable rate (or vice versa) — check the thresholds.
• "ITC benefit" promises: under the concessional scheme there is no ITC, so be sceptical of claims that you will receive credit.

Always insist on a clear cost sheet and, if in doubt, verify the treatment with a tax professional before paying. GST is a legitimate cost on under-construction homes, but it should be charged correctly and only where it actually applies.
