Tata Altroz on-road price in Patna, Bihar (2026)

Is the dearer Altroz worth it in Bihar?

The best-covered upgrade on this car is Accomplished S 1.2 Petrol DCA to Accomplished+ S 1.2 Petrol DCA. In Bihar that costs ₹29,045 more on the road — against ₹25,000 ex-showroom, because road tax is banded on the sticker price — and it adds ₹36,550 of equipment we price, 146% of the ex-showroom rise.

Tata Altroz on-road price in Patna and across Bihar

These are the figures for every city in Bihar. Road tax is set by the state, not the city, so the Smart 1.2 Petrol MT costs the same ₹6,88,169 to put on the road in Patna as it does in Bhagalpur. 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 Bihar charges

Bihar bands the rate by ex-showroom price, from 9% to 12%. The Smart 1.2 Petrol MT pays ₹53,999 of road tax on its ₹5,99,990 ex-showroom price, plus ₹1,080 of cess — the ₹55,079 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.

Bihar taxes diesel up to 1 percentage point 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 Bihar

Bihar 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 Altroz, 2 variants do this.

• Smart 1.2 CNG MT → Pure 1.2 CNG MT

  ₹90,000 more ex-showroom becomes ₹1,10,962 more on the road — ₹20,962 of it from crossing the ₹8,00,000 line, where the rate goes from 9% to 10%.

• Pure 1.2 Petrol AMT → Pure S 1.2 Petrol AMT

  ₹30,000 more ex-showroom becomes ₹42,274 more on the road — ₹12,274 of it from crossing the ₹8,00,000 line, where the rate goes from 9% to 10%.

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 Bihar these upgrades cost more than that.
