Many buyers assume a car is a car — but a T-permit (commercial) car and a private car are governed by completely different rules. The one you should buy depends on whether you want to earn from the vehicle or just use it personally. Here is the full comparison for 2026.
Number Plate and Registration
- Private car: White plate, black lettering, registered for personal use
- T-permit car: Yellow plate, black lettering, registered as a transport vehicle
- Only a T-permit car can legally pick up paying passengers
Tax and Permit Costs
- Private car: One-time road tax at purchase, no permit needed
- T-permit car: Recurring road tax plus permit fees (city, state or All India)
- Commercial vehicles also pay for periodic fitness certification
Insurance
- Private car insurance is cheaper and covers personal use only
- Commercial insurance is costlier but mandatory for any car carrying passengers
- Driving a passenger for hire on private insurance voids your claim
Earning Potential
This is the deciding factor. A private car saves you money on tax and insurance but cannot legally earn. A T-permit car costs more to run but can be put on Ola, Uber, outstation routes or a local taxi stand and earn ₹40,000–₹1,20,000+ per month depending on model, city and hours. If you want income from the vehicle, only a T-permit car works.
Resale and Depreciation
Commercial cars usually run far more kilometres, so they depreciate faster on paper. However, a well-maintained T-permit car with a valid permit sells quickly to other operators because the buyer can start earning immediately. A private car has a wider buyer pool but no earning record to justify its price.
Which Should You Buy?
- Buy a private car if the vehicle is purely for family or personal use
- Buy a T-permit car if you want to run it as a taxi or cab and earn
- Never run a private car as an unofficial taxi — it is illegal and uninsured
What Does "T Permit" Actually Mean?
A T permit (transport permit) car is one registered as a commercial/transport vehicle — yellow number plate, commercial RC, annual fitness, and a permit that allows carrying paying passengers. The "T" you see on Maharashtra plates and in listings simply marks a transport-category registration. A private (white-plate) car may never legally carry paying passengers, which is why Ola/Uber require commercial registration.
Charges to Convert Between Private and T Permit
Converting a private car to commercial costs the road-tax difference between private and commercial rates, a permit fee of ₹5,000–₹15,000, fitness and inspection charges, and a higher insurance premium — the process takes 2–4 weeks. Converting the other way (T permit back to white plate) is possible after clearing dues and surrendering the permit, and typically lifts resale value because private buyers re-enter the market.
