GST on Flat Purchase in Mumbai: What You Need to Know

Buying a flat in Mumbai comes with a long list of costs that go beyond the price your developer quotes. Stamp duty, registration charges, and GST all add to the final amount you pay. Of these, GST is often the most misunderstood. Many buyers only discover it when they receive a payment demand, which leads to confusion about why the number is higher than expected.

This post covers how GST applies to flat purchases in Mumbai, what the current rates are, when you pay it, and which situations are exempt.

How GST Applies to Flat Purchases

GST replaced a patchwork of earlier taxes, including service tax, VAT, and a few state-level levies, when it came into effect in 2017. For residential property, GST applies to under-construction flats. The logic is that buying an under-construction flat is treated as a supply of service by the developer, because the construction work is still ongoing and you are paying for something being built for you.

This is an important distinction. GST does not apply in the same way to all property transactions. The nature of the property and the stage of construction at the time of purchase determines whether GST is payable.

What Are the Current GST Rates on Residential Property?

The GST Council revised the rates applicable to residential property in 2019. The rates currently in effect are:

Affordable housing: 1% GST (without input tax credit). An affordable housing unit in this context is defined as a residential unit with a carpet area of up to 60 square metres in metropolitan cities, including Mumbai, and with a value that does not exceed Rs 45 lakh. Both conditions must be met simultaneously.

Other residential properties (non-affordable): 5% GST (without input tax credit). This applies to all under-construction flats that do not qualify under the affordable housing definition. Most 2 BHK and larger units in Mumbai's suburban and western micro-markets fall under this bracket.

Ready-to-move-in flats: No GST. Once a developer has received the Occupancy Certificate for a project, the sale is treated as a sale of immovable property and is outside the scope of GST. Buyers purchasing a flat from a developer after the OC is issued pay stamp duty and registration charges but not GST.

When Do You Actually Pay GST?

GST on a flat purchase is not a one-time payment made at the time of booking or registration. It is collected across the payment schedule, which means you pay GST proportionately with each instalment you make to the developer.

When you make a payment against a construction-linked plan, the developer raises a payment demand. The GST component is included in that demand and must be paid alongside the principal amount. By the time you reach possession, the full GST amount will have been collected across the instalments.

It is important to keep records of each payment and the GST amounts collected. Your developer should issue a GST invoice for each demand raised. If you are applying for a home loan, confirm with your bank whether the loan covers the GST component or only the base property value, as this varies by lender.

What GST Does Not Apply To

A few elements of a flat purchase are explicitly outside the scope of GST:

Ready-to-move-in units (post-OC): As noted, no GST applies if the Occupancy Certificate has been issued before the sale agreement is executed.

Resale transactions: GST does not apply when you buy a flat from an existing owner. Resale purchases attract only stamp duty and registration charges.

Plots of land: GST does not apply to the sale of land, as land itself is treated as immovable property and not a taxable supply under GST.

Stamp Duty and GST Are Separate

One of the more common points of confusion is whether GST and stamp duty overlap or whether paying one reduces the other. They are entirely separate charges collected by different authorities. GST is a central tax collected by the developer and remitted to the government. Stamp duty is a state tax collected at the time of registration. Both apply to under-construction flat purchases, and neither offsets the other.

For a flat in Mumbai that does not qualify as affordable housing, a buyer should budget for approximately 5% GST on the agreement value during the construction period, plus stamp duty and registration charges at the time of registration.

Checking Your Developer's GST Registration

Before making any payment that includes a GST component, verify that your developer is GST registered. The GST Identification Number (GSTIN) should appear on every payment demand and invoice the developer raises. You can verify a GSTIN on the GST portal to confirm it is valid and active. If a developer is collecting GST but is not registered, that is a red flag that should be addressed before you proceed.

Also retain all GST invoices. These documents may be needed when you apply for a home loan, during any audit, or if a dispute arises about the amounts collected.

Frequently Asked Questions

1. Does GST apply to a flat purchased directly from the developer after the Occupancy Certificate has been issued?

No. Once the Occupancy Certificate has been received, the sale is treated as a sale of immovable property and falls outside the scope of GST. Only stamp duty and registration charges apply in that case.

2. Is GST calculated on the total sale price or only on the construction component?

GST applies to the entire agreement value for under-construction residential properties. There is no bifurcation for land and construction components under the current simplified rate structure applicable from April 2019.

3. What is the GST rate for a 2 BHK flat in Mumbai priced at Rs 90 lakh?

A flat valued at Rs 90 lakh does not meet the Rs 45 lakh threshold for affordable housing, regardless of carpet area. GST will apply at 5% on the agreement value.

4. Can I claim input tax credit on GST paid for my flat purchase?

Individual homebuyers cannot claim input tax credit on GST paid for a residential flat purchase. Input tax credit is not available to end buyers under the current residential property GST framework.

5. Does GST apply if I buy a flat through a resale transaction?

No. GST does not apply to resale transactions. When you purchase a flat from an existing owner, only stamp duty and registration charges apply. GST is relevant only for purchases from a developer for under-construction properties.
