Tata Sierra on-road price in Guwahati, Assam (2026)

Is the dearer Sierra worth it in Assam?

The best-covered upgrade on this car is Adventure+ 1.5 Diesel AT to Accomplished 1.5 Diesel AT. In Assam that costs ₹1,56,843 more on the road — against ₹1,35,000 ex-showroom, because road tax is banded on the sticker price — and it adds ₹2,17,000 of equipment we price, 160% of the ex-showroom rise.

Tata Sierra on-road price in Guwahati and across Assam

These are the figures for every city in Assam. Road tax is set by the state, not the city, so the Smart+ 1.5 Petrol MT costs the same ₹13,38,008 to put on the road in Guwahati as it does in Dibrugarh. The only thing that moves between showrooms is the dealer handling charge, which is not a published figure — so it is not in any total on this page.

What Assam charges

Assam bands the rate by ex-showroom price, from 6% to 14%. The Smart+ 1.5 Petrol MT pays ₹1,14,900 of road tax on its ₹11,49,000 ex-showroom price, plus ₹2,068 of cess — the ₹1,16,968 the table shows. That cess is 0.18% of ex-showroom, and we bill it because it appears at exactly that rate on every invoice we checked, in all 36 states and union territories. We have not found the notification that sets it, so we describe it rather than name it.

Assam taxes diesel up to 4 percentage points higher than petrol, so the same trim costs more to register on that fuel here than the ex-showroom gap suggests.

The tax boundary to watch in Assam

Assam re-rates the whole price once a car crosses a band, so a small move up the range can cost several times its ex-showroom difference. On the Tata Sierra, 2 variants do this.

• Accomplished 1.5 Turbo Petrol AT → Accomplished+ 1.5 Turbo Petrol AT

  ₹1,00,000 more ex-showroom becomes ₹2,00,140 more on the road — ₹1,00,140 of it from crossing the ₹20,00,000 line, where the rate goes from 10% to 14%.

• Accomplished 1.5 Diesel AT → Accomplished+ 1.5 Diesel MT

  ₹30,000 more ex-showroom becomes ₹1,16,014 more on the road — ₹86,014 of it from crossing the ₹20,00,000 line, where the rate goes from 10% to 14%.

Worth knowing before you pick a trim: our verdict on whether the equipment justifies the gap is based on the ex-showroom difference, and in Assam these upgrades cost more than that.
