Our mission
Most car buyers compare ex-showroom prices and then face a 10–18% tax shock at the dealership. In India, road tax alone ranges from 4% in Delhi to 14.5% in Karnataka. In the US, state sales tax swings from 0% in Oregon to 9.75% in parts of Tennessee. This confusion costs buyers real money.
CarTax.online exists to eliminate that gap. We give every buyer — whether in Mumbai, Dallas, or Melbourne — a clear, itemized cost estimate before they sign anything. Our calculators apply country-specific and state-specific tax logic, not rough averages, so the number you see reflects your actual purchase.

Road tax in Karnataka is 13%, in Delhi 4–10%, in Texas 6.25%. We apply the correct state or territory rate for your specific location, not a national average.

Original editorial content
Our blog covers GST changes, pay commission updates, federal tax law shifts, and car buying guides — written from first principles, not scraped from elsewhere.
Editorial policy
Every calculator on CarTax.online is built from official tax schedules — India's GST Act, state motor vehicle taxation acts, US state department of revenue tables, and country-level import duty schedules. We do not scrape, syndicate, or copy content from other websites.
Our blog covers tax law changes, car buying guides, and financial decisions around vehicle purchases. Articles are written by the CarTax team and researched from primary sources: Ministry of Finance notifications, IRS publications, SIAM data, and official government portals. We link to these sources directly so you can verify every claim.
Calculator results are clearly labeled as planning estimates. We recommend verifying final figures with your RTO, dealer F&I office, or state DMV before payment. Tax rates change — we update our logic as frameworks evolve and note the last-reviewed date on major pages.
How our calculators work
- 1
You enter the car details
Ex-showroom price, engine type, fuel type, and your state or territory. For India, we also ask about the vehicle segment (electric, hybrid, petrol/diesel below 1200cc, above 4m SUV) since GST slabs depend on these attributes.
- 2
We apply location-specific tax logic
Our engine pulls the correct GST rate, compensation cess, state road tax percentage, registration charges, and any applicable exemptions (EV subsidy, BH Series, FAME incentives, state EV policy) for your exact inputs.
- 3
You see the full itemized breakdown
Ex-showroom, GST, cess, road tax, registration, insurance estimate, hypothecation — each line shown separately. You can adjust inputs and recalculate instantly without reloading the page.
Advertising transparency
CarTax.online is free because we display Google AdSense advertisements. Ads are served by Google and placed in clearly separated zones — never inside calculator results, never disguised as navigation links, and never positioned to interfere with your use of the tool. We follow Google's AdSense program policies. If you ever see an ad that appears misleading or inappropriate, please contact us and we will review it immediately.
