Buying a home is a significant financial decision, and understanding the applicable taxes is essential before making a purchase. One of the most common questions among homebuyers is whether GST on under-construction property is applicable and how much tax they need to pay.
In India, the Goods and Services Tax (GST) generally applies when you purchase a residential property that is still under construction. The applicable rate is usually 1% for qualifying affordable housing and 5% for other residential apartments, subject to the relevant conditions. However, a completed property sold after the required completion certificate has been issued is generally exempt from GST.
Understanding these rules can help buyers estimate their total property cost, compare under-construction and ready-to-move-in homes, and avoid unexpected expenses during the purchase process.
This guide explains the applicable GST rates, calculation methods, exemptions, and important considerations for property buyers in India.
What Is GST on Under-Construction Property?
GST on under-construction property is the tax applicable to the construction service supplied by a builder or developer when a property is sold before completion under the applicable GST provisions.
When you book an apartment in a project that is still being constructed, the builder may charge GST on the taxable value of the property. The amount depends on the type of property, its eligibility for affordable housing benefits, and the applicable tax scheme.
The GST framework for residential real estate was revised with effect from 1 April 2019, introducing lower effective rates for qualifying residential construction, generally without input tax credit for the developer under the new scheme.

For buyers, the most important distinction is whether the property is under construction or is a completed property sold after the issuance of the required completion certificate or first occupation, whichever is earlier.
GST Rates on Under-Construction Property in India
The applicable GST rate depends on whether the residential apartment qualifies as affordable housing.
| Property type | GST rate | Input tax credit |
| Affordable residential apartment | 1% | Not available |
| Other residential apartment | 5% | Not available |
| Qualifying completed property | No GST | Not applicable |
These are the effective GST rates under the concessional residential construction scheme introduced in 2019. The standard residential rates are subject to the applicable conditions and valuation rules.

1. GST on Affordable Housing
The GST rate on a qualifying affordable residential apartment is 1%, without input tax credit for the builder.
Under the applicable definition, an affordable residential apartment must generally meet both of these conditions:
- The carpet area must not exceed 60 square metres in metropolitan cities or 90 square metres in non-metropolitan cities.
- The gross amount charged for the apartment must not exceed ₹45 lakh.
Both the area and price conditions must be satisfied for the apartment to qualify. The relevant definitions and project conditions should be checked before relying on the concessional rate.

2. GST on Non-Affordable Residential Property
For residential apartments that do not qualify as affordable housing, the applicable GST rate is generally 5% under the concessional scheme.
For example, if you purchase an under-construction apartment worth ₹80 lakh, the GST calculation may be as follows:
- Property value: ₹80,00,000
- Applicable GST rate: 5%
- GST amount: ₹4,00,000
- Total cost, including GST: ₹84,00,000
This is an illustrative calculation. The actual taxable value must be determined according to the applicable GST valuation provisions and the terms of the agreement.
How to Calculate GST on Under-Construction Property
Calculating GST before booking a property helps you plan your budget and understand the total amount payable to the builder.
Under the applicable real estate valuation rules, one-third of the total amount charged is generally treated as the value of the land, with the remaining two-thirds forming the taxable value for the construction service.
This means the effective 1% and 5% rates are commonly calculated on the total amount charged for the apartment, subject to the applicable conditions.

Example: GST Calculation for a ₹60 Lakh Flat
Suppose you are purchasing a non-affordable under-construction apartment for ₹60 lakh.
| Particulars | Amount |
| Total property value | ₹60,00,000 |
| GST rate | 5% |
| GST payable | ₹3,00,000 |
| Total price including GST | ₹63,00,000 |
For an eligible affordable apartment priced at ₹40 lakh, the calculation would be:
| Particulars | Amount |
| Total property value | ₹40,00,000 |
| GST rate | 1% |
| GST payable | ₹40,000 |
| Total price including GST | ₹40,40,000 |
These examples assume the stated property values are the amounts to which the effective GST rates apply. Additional charges, contractual terms, and eligibility conditions may affect the final amount.
Is GST Applicable on Ready-to-Move-In Property?
No. GST is generally not applicable to the sale of a completed property when the entire consideration is received after the issuance of the completion certificate by the competent authority, where required, or after its first occupation, whichever is earlier.
This distinction is important when comparing an under-construction apartment with a ready-to-move-in property.
For example, if you purchase a completed flat for ₹75 lakh after the applicable completion milestone, GST generally does not apply to the property sale. However, stamp duty and property registration charges may still be payable.
The exemption relates to the sale of the completed property. Separate services or transactions associated with the purchase may have their own tax treatment.

GST on Under-Construction Property vs Ready-to-Move-In Property
Before deciding which property to purchase, compare the tax implications and other costs.
| Factor | Under-construction property | Completed property |
| GST | Generally 1% or 5% for residential apartments under the concessional scheme | Generally no GST if the completion conditions are met |
| Possession | At a future date | Usually available sooner |
| Construction risk | Potential delays or changes | Construction is completed |
| Stamp duty | Applicable as per state law | Applicable as per state law |
| Registration charges | Applicable as per state law | Applicable as per state law |
The absence of GST does not automatically make a completed property cheaper. Buyers should compare the total price, location, amenities, possession timeline, and other charges before making a decision.
Is GST on Under-Construction Property Included in the Agreement Value?
GST may be included in the overall quoted price or charged separately, depending on the builder’s pricing structure and the terms of the sale agreement.
Before booking an apartment, ask the developer for a detailed cost sheet that clearly identifies:
- Basic sale price
- GST amount and applicable rate
- Parking charges, where applicable
- Clubhouse and amenity charges
- Maintenance deposits
- Stamp duty and registration charges
- Other applicable fees
Check whether the advertised property price is inclusive or exclusive of GST. A clear cost breakdown helps prevent confusion when instalment demands are issued.
Can a Buyer Claim Input Tax Credit on GST Paid for a Flat?
Generally, an individual purchasing a residential apartment for personal use cannot claim input tax credit for the GST paid on the purchase.
Under the concessional residential construction scheme, developers are also generally not entitled to claim input tax credit on inputs and input services used for the qualifying residential construction supplies.
The lower effective GST rates of 1% and 5% are linked to the no-ITC conditions of this scheme.

Buyers should therefore treat GST as part of the overall acquisition cost rather than assume it can be recovered later.
What Happens If You Book a Flat Before Construction Is Completed?
When you book an apartment before completion, the builder may collect payments in stages according to the construction-linked plan or the payment schedule specified in the agreement.
The GST treatment depends on the applicable provisions, the nature of the supply, the project scheme, and the relevant time-of-supply rules.
If you booked a property under an older project or a project that falls under a different tax arrangement, the applicable rate may require additional examination. The revised rates introduced in April 2019 included specific provisions for ongoing projects and options available to developers.

For this reason, buyers should not rely only on the booking date. Review the builder’s GST invoice, the project details, and the applicable tax provisions.
GST on Commercial Under-Construction Property
GST treatment for commercial property can differ from the treatment of residential apartments.
Commercial units, such as shops and offices, may fall under different provisions depending on the type of project and the tax scheme selected or applicable to the developer.
For example, the concessional residential real estate framework provides specific treatment for commercial apartments within residential real estate projects, while other commercial construction supplies may be taxed under different provisions.

If you are buying an office, shop, or commercial unit, confirm the applicable GST rate with the developer or a qualified tax professional before making the payment.
GST on Under-Construction Property: Important Things to Check Before Buying
A property purchase involves several financial and legal checks. Before paying the booking amount, consider the following:
- Confirm the property status: Check whether the project is under construction or has received the relevant completion certificate.
- Verify the GST rate: Ask the builder to explain why the property qualifies for the stated rate.
- Check affordable housing eligibility: Confirm both the carpet-area and price requirements.
- Review the cost sheet: Ensure GST is clearly mentioned and identify any additional charges.
- Check the sale agreement: Understand whether GST is included in the quoted price or payable separately.
- Keep all invoices: Retain booking receipts, demand letters, and GST invoices for your records.
- Verify the project details: Review the project’s registration and approvals before committing to the purchase.
These checks can help you make a more informed decision and reduce the risk of unexpected costs.
