Let’s recap the key takeaways from this guide to ensure you stay ahead of the curve:
1. GST on Flats: Clarity Saves Money
From under-construction properties (5% GST) to affordable housing (1%), knowing the right GST rate helps you budget effectively. Remember, ready-to-move-in flats with occupancy certificates are GST-free, so always verify the property’s status before signing deals.

2. Cars: Balance Luxury and Savings
Luxury cars may come with a hefty 43% tax (28% GST + 15% cess), but EVs at 5% GST offer a greener, cheaper alternative. If you’re a business owner, don’t forget to claim Input Tax Credit (ITC) on vehicles used for commercial purposes. This small step can save lakhs over time.

While smartphones attract 18% GST, only businesses can claim refunds on devices used for operations. For freelancers and startups, this means every phone bought for your team is a tax-saving opportunity.
4. Who Pays GST? Transparency is Key
Builders may handle GST paperwork, but buyers ultimately bear the cost for under-construction properties. Always cross-check invoices and verify the builder’s GSTIN to avoid scams. The 2025 GST grievance portal empowers you to report discrepancies instantly.
5. Stay Updated, Avoid Mistakes
The 2025 GST tweaks, like reduced rates on solar panels (12%) and UPI payment incentives, reflect India’s push toward sustainability and digital growth.
