The Indian automotive market has been buzzing with excitement, and for good reason! The government’s strategic GST reforms, effective September 22, 2025, have ushered in a new era of affordability for compact SUVs. For those with their hearts set on the stylish and feature-packed Kia Sonet, this news is nothing short of spectacular. If you’ve been contemplating owning this head-turning vehicle, the revised Kia Sonet price after GST cut is the definitive sign you’ve been waiting for. Let’s delve deep into the significant savings and unravel the full impact of new GST on Kia Sonet price.
The Game-Changing GST Revision: A Boon for Compact SUVs
The core of this exciting development lies in the updated GST 2.0 framework. Under the previous regime, compact SUVs like the Kia Sonet, typically falling under the 4-meter length with specific engine capacities, were subject to a 28% GST along with a 1% cess, bringing the total effective tax to 29%.
The new legislation simplifies and reduces this considerably, now applying a flat 18% GST for this segment. This substantial 11% reduction in the effective tax rate is a direct benefit that manufacturers are passing on to consumers, resulting in a considerable Kia Sonet price drop across its extensive variant lineup.

Kia Sonet New Price List After GST: A Closer Look at the Savings
Kia India has promptly implemented the GST benefits, making its already popular Sonet even more accessible. Let’s examine the anticipated Kia Sonet old price vs new price after GST for some of the most sought-after petrol and diesel variants.
Note: These prices are ex-showroom and are approximate based on the 11% effective tax reduction. Final prices may have minor variations from the manufacturer.
As the table clearly illustrates, the savings are significant across the board. The Kia Sonet petrol price after GST and Kia Sonet diesel price after GST have both seen substantial reductions, with potential savings exceeding ₹1.25 Lakh on higher-end diesel automatic variants. This makes the Sonet an even stronger contender in the fiercely competitive compact SUV segment.
What You Actually Pay: Kia Sonet On-Road Price After GST
The ex-showroom price is just one part of the equation; the actual Kia Sonet on-road price after GST is what matters when you drive it home. The on-road price includes the ex-showroom price, RTO (Road Tax), and insurance. Since both RTO and insurance premiums are calculated based on the ex-showroom value, the GST reduction creates a positive ripple effect, leading to a lower final price for the customer.
For example, in a state like Kerala, the Kia Sonet price in Kerala after GST will see a notable decline in its on-road cost. This will undoubtedly boost its appeal in a market that appreciates value and features.

How Much is Kia Sonet Cheaper After GST?
The direct answer is impressive: the Kia Sonet is now approximately 8.5% cheaper across its entire range of variants. This translates to savings ranging from roughly ₹68,000 on the base petrol model to over ₹1.25 Lakh on the top-spec diesel automatic. This considerable reduction makes the Sonet’s premium features, bold design, and powerful engine options even more attainable for a wider audience.
Why the Kia Sonet Remains a Top Choice
Even before the GST cut, the Kia Sonet stood out with its:
- Segment-first features: Ventilated seats, Bose sound system, 10.25-inch touchscreen.
- Multiple powertrain options: Including iMT and a quick DCT for petrol, and a refined automatic for diesel.
- Striking design: A bold and dynamic exterior that captures attention.
- Strong safety package: Ensuring peace of mind for occupants.
With the new prices, the Sonet simply becomes an unbeatable proposition in its segment, offering an unparalleled blend of style, features, performance, and now, exceptional value.
