- February 8, 2025

Picture this: You’ve finally found your dream home in that perfect neighborhood. The builder’s office is ready with the paperwork, but wait – what’s this additional GST on under-construction flats they’re talking about? If you’re confused about how GST affects your home purchase and worried about hidden costs, you’re not alone. Let’s break it down together.
GST Decoded: Why It Matters for Under-Construction Flats
The Goods and Services Tax has changed how we look at property purchases in India. Understanding GST for under-construction flats is crucial because it directly impacts your total investment and can add significant costs to your dream home purchase.
- Basic GST Structure: Currently, GST on property under construction stands at 5% for regular housing and 1% for affordable housing projects (as per the 33rd GST Council Meeting, February 2019).
- Input Tax Credit (ITC): Before 2019, builders could claim ITC and charge 12% GST. The new reduced rates without ITC have simplified the process for homebuyers.
- Coverage Scope: Residential property GST applies only to under-construction properties. Ready-to-move-in properties with completion certificates are GST-exempt.
Pro Tip: Always check if your property falls under the new or old GST regime, as this can significantly impact your final costs.
Breaking Down GST Rates: Affordable vs. Premium Housing
When it comes to GST for property, rates vary based on your property type. According to the Ministry of Housing and Urban Affairs, affordable housing has specific criteria that determine GST applicability.
- Affordable Housing Criteria: Properties up to 60 square meters in non-metropolitan cities and 90 square meters in metropolitan cities, priced under ₹45 lakhs, qualify for the 1% GST rate.
- Premium Housing: All other properties attract 5% GST on flat purchases, making it essential to calculate these costs before finalizing your budget.
- Metropolitan vs. Non-Metropolitan: Cities like Delhi-NCR, Mumbai-MMR, Chennai, Kolkata, Bengaluru, and Hyderabad fall under the metropolitan category with different criteria:
- Monthly maintenance charges: Higher threshold of ₹7,500 for metropolitan cities versus ₹5,000 for non-metropolitan areas before 18% GST applies.
- Construction cost variation: Metropolitan cities have a higher deemed construction cost percentage (65% of total amount) compared to non-metropolitan areas (55%) for GST calculation.
This distinction by the GST Council acknowledges the cost variations and living standards across different city categories.
Please Note: According to CREDAI data (2023), about 40% of new launches fall under the affordable housing segment, making the 1% GST rate applicable to a significant portion of buyers.
The True Cost: How GST Impacts Your Property Price
Before finalizing your purchase, understanding how GST for apartment purchase affects your total cost is crucial. Recent market analysis shows GST can add 1-5% to your property cost.
- Base Price Impact: The GST is calculated on the base price, excluding stamp duty and registration charges. For example, on a ₹50 lakh property, GST at 5% would be ₹2.5 lakhs.
- Construction Stage Matters: The earlier you book, the more GST on home you pay, as GST applies to remaining construction costs.
- Additional Costs: Remember to factor in stamp duty (typically 5-7%) and registration charges (1%) along with GST on flat purchase.
Example: For a ₹75 lakh under-construction property, the total additional costs would include ₹3.75 lakhs as GST (5%), ₹4.5 lakhs as stamp duty (6%), and ₹75,000 as registration charges (1%).
Exemptions and Perks: What Every Buyer Should Know
Several exemptions exist when it comes to under-construction property GST, potentially saving you significant amounts. Let’s explore what you might be eligible for.
- Ready-to-Move-In Properties: Properties with completion certificates or occupation certificates are completely exempt from GST.
- Land Value Deduction: One-third of the total amount is deducted towards land value before GST calculation, effectively reducing your tax burden.
- Resale Properties: Secondary market properties are GST-exempt, making them an attractive option for budget-conscious buyers.
Pro Tip: Keep all payment receipts and ensure your builder mentions GST components clearly in the agreement.
Smart Buying: Essential GST Tips for Homebuyers
Making an informed decision about your GST for apartment purchase can save you lakhs of rupees. Here’s what smart buyers should consider.
- Timing Your Purchase: Consider buying when construction is nearly complete to minimize GST impact, as you only pay for remaining construction.
- Documentation Check: Ensure your builder has registered under GST and provides proper tax invoices for all payments.
- Budget Planning: Always add 10-15% to your base budget for GST and other taxes when planning your property purchase.
Please Note: According to Knight Frank India’s H2 2023 report, 68% of new launches are under construction, making GST understanding crucial for most buyers.
Conclusion
Understanding GST on under-construction flats doesn’t have to be complicated. By staying informed about rates, exemptions, and calculations, you can make a smart property investment decision. Remember, the key is to factor in all costs upfront and work with reliable builders who maintain transparency in their GST practices.
FAQs
- If I buy a ready-to-move-in flat, do I need to pay GST?

No, individual homebuyers cannot claim input tax credit on GST for under-construction flats. The current GST rates (5% and 1%) are already reduced rates that factor in this limitation. - What happens if my builder asks for GST on parking charges?
