BH Series Calculator: 2-Year Tax, 14-Year Schedule and State Break-Even

What the BH Series Actually Is

The Bharat series, written BH on the number plate, is a nationwide vehicle registration introduced by the Ministry of Road Transport and Highways in 2021. Its whole point is mobility. If you move from one state to another, a normal registration forces you to re-register the car in the new state within twelve months, pay road tax there all over again, and chase a refund of the tax you already paid at home, a refund that is slow, partial and often simply never comes. The BH series removes that pain. A vehicle on a BH plate is valid in every state and union territory, so you can move from Pune to Bengaluru to Gurugram without touching the RTO each time.

The trade-off is how you pay for it. A normal private car pays road tax once, a single lifetime lump sum that covers fifteen years. A BH vehicle pays in two-year blocks instead. You pay for the first two years at registration, then renew every two years for the first fourteen years, and annually after that. So BH is not automatically cheaper or dearer, it is a different payment structure, and whether it saves you money depends entirely on your state’s lifetime rate. That is the comparison this calculator is built around, and the one almost every other BH tool leaves out.

How the MoRTH Formula Works, Including the 1.25 Factor

The BH tax is set by Rule 51B of the Central Motor Vehicles Rules, notified in the MoRTH gazette (CG-DL-E-27082021-229283). The calculation runs in three steps, and the third step is where most online calculators go wrong.

Step 1, find your slab. The rate is a percentage of the invoice price of the vehicle excluding GST. It is 8 percent for a vehicle costing under 10 lakh, 10 percent for 10 to 20 lakh, and 12 percent above 20 lakh. This gives your fifteen-year base tax.

Step 2, adjust for fuel. A diesel vehicle pays 2 percentage points more, so an 8 percent car becomes 10 percent. An electric vehicle pays 2 percentage points less. Petrol and CNG use the base rate.

Step 3, apply the 1.25 factor for the two-year payment. This is the step that trips up half the calculators online. The two-year tax is not simply the fifteen-year base divided by 7.5. The correct formula multiplies the base by 1.25, then by 2 years, then divides by 15: two-year tax equals (base tax multiplied by 1.25 multiplied by 2) divided by 15. The 1.25 factor is a deliberate loading in the rule, and any tool that skips it understates your tax by a fifth. Our calculator applies it exactly as the gazette specifies.

BH Series Slab Rates at a Glance

Rates are applied to the invoice value excluding GST, then loaded by the 1.25 factor for the two-year payment.

BH vs State Lifetime Road Tax: The Comparison Nobody Else Shows

Here is why the state comparison matters. Over fourteen years a BH vehicle pays seven two-year blocks. For a 10 lakh petrol car that is about 1.17 lakh in total. Whether that beats paying your state’s lifetime tax once depends on your state’s rate. States with high lifetime rates make BH look attractive, states with low flat rates make a normal registration cheaper. The table below uses indicative lifetime rates for a 10 lakh petrol car so you can see the pattern. Use the calculator above for your exact vehicle and state.

State rates are indicative representative slabs, not exact for every vehicle. Verify your state’s rate on the Vahan portal or with your RTO before deciding.

Three Real Examples, Three Cities

Priya in Bengaluru, 12 lakh petrol SUV. Priya works for an IT company with offices across the country, so she qualifies for BH. Her invoice value excluding GST is about 10.5 lakh, which sits in the 10 percent slab. Her fifteen-year base tax is 1.05 lakh, and her two-year BH payment works out to (1.05 lakh times 1.25 times 2) divided by 15, roughly 17,500. Over fourteen years she will pay about 1.22 lakh. Karnataka’s lifetime tax on the same car would be around 1.63 lakh, so BH saves Priya roughly 40,000, and she avoids re-registration if her employer moves her to another city.

Rahul in Pune, 8 lakh petrol hatchback. Rahul is a central government employee, automatically eligible for BH. His car sits in the 8 percent slab, giving a base tax of 64,000 and a two-year payment of about 10,667. Maharashtra’s lifetime rate on a small petrol car is around 11 percent, about 88,000. Rahul’s BH fourteen-year total is about 74,700, so BH is cheaper for him too, and far more convenient given he expects a transfer within three years.

Anjali in Ahmedabad, 15 lakh diesel car. Anjali’s case flips the answer. Her diesel car in the 10 to 20 lakh band attracts 10 percent plus 2 percent for diesel, so 12 percent, a base tax of 1.8 lakh and a two-year payment of about 30,000. Over fourteen years that is 2.1 lakh. Gujarat, however, charges a flat 6 percent lifetime, only about 90,000 on the same car. For Anjali, staying on a normal Gujarat registration is dramatically cheaper, and BH only makes sense if she is certain she will move states. This is exactly why the break-even matters.

Are You Even Eligible for BH?

The BH series is not open to everyone, and buying a car expecting BH only to find you do not qualify is a common and expensive surprise. You are eligible if you fall into one of these groups.

• Central government employees and central public sector undertaking staff.
• State government employees and state PSU staff.
• Defence personnel.
• Private-sector employees whose employer has offices in four or more states or union territories. This is the route most private buyers use, and it requires a working certificate (Form 60) from the employer.

If you do not fit any of these, you cannot register on a BH plate, and this calculator’s comparison is academic for you, a normal state registration is your only option. If you do qualify, the eligibility is tied to your employment, so check that your employer can issue the required documentation before you commit.

Does BH Work for Bikes and Two-Wheelers?

Yes. The BH series applies to two-wheelers exactly as it does to cars, using the same slab percentages on the invoice value and the same 1.25 factor for the two-year payment. Because most bikes cost well under 10 lakh, almost every two-wheeler sits in the 8 percent slab. A 1.5 lakh bike, for example, has a base tax of 12,000 and a two-year BH payment of about 2,000. The eligibility rules are identical, and the mobility benefit is the same, useful if you are a government employee or a transferable private-sector worker who wants to take the bike across state lines without re-registration. Select bike in the calculator above to model your two-wheeler.

Six Things to Know Before Choosing BH

• Run the break-even first. BH is a convenience product, not automatically a discount. In low-tax states like Gujarat or Himachal, a normal registration is often cheaper. Compare before you decide.
• Confirm eligibility in writing. Private buyers need their employer’s Form 60 confirming offices in four or more states. Get it before booking the car.
• Budget for the renewal. BH is not fire-and-forget. You must renew every two years, and missing it attracts penalties. Set a reminder.
• Watch the 1.25 loading. The two-year figure already includes the 1.25 factor, so BH is not as cheap per year as a naive division suggests. Our calculator shows the true number.
• Diesel changes the maths. The 2-point diesel loading can push BH above a low-tax state’s lifetime rate. Diesel buyers should check the comparison especially carefully.
• EV buyers, check state waivers. Many states waive road tax on EVs entirely, which usually beats BH. If your state offers a full EV waiver, a normal registration is likely free and cheaper than BH.

BH Series Quick Reference

The Problem BH Was Built to Solve

To understand whether BH is right for you, it helps to understand the mess it replaced. Under the normal system, road tax is a state subject. When you buy a car in Maharashtra you pay Maharashtra its lifetime road tax, often 11 to 13 percent of the value, and you get a Maharashtra registration valid there. The trouble starts when life moves you. If your job takes you to Karnataka, the law gives you twelve months before you must re-register the vehicle in Karnataka. Re-registration means paying Karnataka its road tax too, on the same car, and then applying to Maharashtra for a refund of the unused portion of the tax you already paid.

In theory the refund makes you whole. In practice it rarely does. Refunds are calculated on a depreciated basis, so you get back far less than you paid, the paperwork crosses two state bureaucracies that have no incentive to cooperate, and families routinely report waiting years or simply giving up. A transferable professional could easily pay road tax three or four times over the life of one car. The BH series was MoRTH’s answer, a single registration that follows you anywhere, with tax paid in small two-year blocks so you are never locked into a large lifetime payment to a state you might leave. Seen this way, BH is insurance against the refund trap as much as it is a tax structure.

Who Genuinely Benefits, and Who Does Not

The calculator gives you a rupee answer, but the decision has a human side the numbers alone miss. BH clearly benefits people whose careers are mobile by design. A central government officer on a transferable posting, a defence family that relocates every few years, a consultant or IT professional whose employer shuffles staff between metro offices, these are the people for whom BH pays for itself in avoided re-registration and avoided refund battles, often several times over. For them, even in a state where BH is slightly more expensive on paper, the convenience is worth the premium.

Equally, BH is a poor fit for people who are settled. If you have bought a house in your city, your job is local, and you expect to keep the car for its full life in one state, a normal lifetime registration is simpler and usually cheaper, particularly in a low-tax state. Paying every two years and tracking renewals is pure friction with no offsetting benefit if you never cross a state line. The honest advice is to be realistic about your next ten years, not your ideal ones. If there is a genuine chance of an inter-state move, BH earns its place. If not, it rarely does.

How Your State Changes the Answer

Because the BH cost is fixed by a central formula but the alternative is your state’s lifetime rate, the entire decision hinges on where you live. The spread between states is enormous. At the high end, Karnataka can charge 13 to 18 percent depending on price, Kerala and Tamil Nadu sit around 13 to 15 percent, and Telangana and Andhra Pradesh are similar. In these states a 10 lakh car attracts 1.3 to 1.6 lakh in lifetime tax, comfortably more than the roughly 1.17 lakh a BH vehicle pays over fourteen years, so BH wins on cost as well as convenience.

At the low end the picture reverses. Gujarat charges a flat 6 percent on the pre-GST invoice, so the same 10 lakh car costs about 90,000 for life, well below the BH total. Himachal Pradesh starts as low as 2.5 percent, and the union territory of Dadra and Nagar Haveli is famously the cheapest in the country at a flat 2.5 percent, which is why so many high-value cars are registered there. In these places a normal registration is dramatically cheaper, and BH only makes sense if you are certain you will move. States in the middle, Delhi, Haryana, Uttar Pradesh, Madhya Pradesh and West Bengal, land in the 8 to 11 percent range where the answer is close and genuinely depends on your exact car and fuel. That is precisely the case where running the calculator matters most.

Putting BH Tax in the Context of Total Ownership

Road tax, whether BH or lifetime, is only one line in the true cost of owning a vehicle, and it helps to keep it in proportion. Over a typical ten-year ownership, fuel usually dwarfs road tax, a car driven 12,000 kilometres a year on petrol can burn through eight to ten lakh in fuel alone. Insurance adds another two to three lakh, servicing and tyres a lakh or more, and depreciation quietly removes the largest sum of all. Against that backdrop a difference of thirty or forty thousand rupees between BH and a normal registration is real money but not the deciding factor for most buyers, the convenience of not re-registering often matters more.

This is why the smartest way to use this page is alongside the rest of your vehicle planning. Work out your BH tax and break-even here, then estimate your running costs with the fuel calculator, your loan with the EMI calculator, and your state’s lifetime figure with the road-tax calculator. Seen together, the BH decision becomes clear, it is a convenience-versus-cost trade-off on one modest line of a much larger budget, and for a mobile professional the convenience usually wins.

BH Series for Electric Vehicles: Usually the Wrong Choice

Electric vehicles deserve their own discussion because the answer is counterintuitive. Under the BH formula an EV gets a two percentage point discount, so a 15 lakh EV in the 10 to 20 lakh band pays 8 percent rather than 10. That sounds attractive until you look at what a normal registration costs an EV in most states. To push electric adoption, the majority of Indian states currently waive road tax on electric vehicles entirely, a full one hundred percent exemption. Maharashtra, Delhi, Tamil Nadu, Telangana, Gujarat, Rajasthan, Haryana and Uttar Pradesh all offer complete or near-complete waivers.

The arithmetic is then simple. A normal EV registration in those states costs nothing in road tax, while BH still charges its discounted percentage across fourteen years. For a 15 lakh EV, BH would take well over a lakh over its life, versus zero for a normal registration in a waiver state. Unless you are certain you will relocate to a state that taxes EVs, or your home state is one of the few without a waiver such as Kerala or Madhya Pradesh, a normal EV registration almost always beats BH. The calculator reflects this, if you pick an EV and a waiver state, it will tell you plainly that normal registration is cheaper. It is a good example of why blindly choosing BH, or trusting a tool that only shows the BH number, can cost you real money.

Diesel Vehicles and the Two-Point Loading

Diesel buyers face the opposite pressure. The BH formula adds two percentage points for diesel, so a diesel car under 10 lakh pays 10 percent rather than 8, and one in the 10 to 20 lakh band pays 12 rather than 10. Over fourteen years that loading adds up. A 15 lakh diesel SUV on BH pays around 2.1 lakh in total, and in a low-tax state that is far more than the lifetime alternative, Gujarat’s flat 6 percent would charge only about 90,000 on the same vehicle. Even in a mid-tax state the diesel loading narrows or erases the BH advantage that a petrol version of the same car would enjoy.

The practical takeaway is that fuel type can flip the decision entirely for the same buyer. A family choosing between a petrol and a diesel variant of the same SUV might find BH sensible for the petrol version and clearly wrong for the diesel one, purely because of the two-point loading interacting with their state’s rate. This is exactly the kind of interaction a single-number calculator hides and a proper break-even reveals. If you are a diesel buyer, model your real state and rate before assuming BH is the mobile-friendly bargain it is often made out to be.

The Bottom Line on BH Series

The BH series is one of the more genuinely useful reforms in Indian vehicle registration, but it is widely misunderstood as a discount when it is really a convenience. Whether it saves you money comes down to two things the calculator on this page puts side by side, the correct MoRTH tax including the 1.25 factor, and your own state’s lifetime rate. In high-tax states BH tends to win on both cost and convenience. In low-tax states it wins only on convenience, and only if you actually move. For EVs in waiver states it usually loses, and for diesel vehicles the two-point loading demands a careful check.

Use the tool above with your real invoice value, fuel type and home state, read the fourteen-year schedule rather than just the first payment, and confirm your eligibility in writing before you commit. Do that, and you will make the BH decision on facts rather than on the half-formula figures floating around most of the internet. That clarity, the right number and the right comparison in one place, is exactly what this calculator was built to give you.

How to Register a Vehicle on the BH Series

If the calculator tells you BH makes sense, here is how the registration actually happens, because the process differs slightly from a normal registration and catches first-timers out. The application is made through the Vahan portal, either by you or, more commonly, by the dealer at the point of purchase. You select the BH series option during registration rather than the standard state series, and this choice is made once, at first registration, it is not something you switch to later.

The documents fall into two buckets. The standard set is the same as any registration, the vehicle invoice, proof of insurance, your identity and address proof, and the temporary registration if the dealer issued one. The BH-specific document is proof of eligibility. Government and defence employees provide their official identity card or service certificate. Private-sector employees provide Form 60, a working certificate issued by the employer confirming it operates offices in four or more states or union territories, this is the single most important document and the one most likely to cause delay, so request it early. Once submitted, the RTO verifies eligibility, calculates the two-year tax using the MoRTH formula, and issues the BH plate. The tax you pay at this stage is the first two-year block, and the system will expect the next payment before that block expires.

Reading Your 14-Year Payment Schedule

One thing the calculator makes concrete that competitors hide is the full schedule. When you enter your car, the chart above plots the cumulative tax you will pay across fourteen years in seven steps. This matters because BH can feel deceptively cheap at the counter, you hand over one two-year block and drive away, but the commitment is seven blocks. Seeing the cumulative line climb helps you plan, and it makes the comparison with a one-time lifetime payment honest.

Take the 10 lakh petrol car again. Each two-year block is about 16,667. At the end of year two you have paid 16,667, at year four 33,334, at year six 50,000, and so on, reaching about 1.17 lakh by year fourteen. A lifetime registration in a high-tax state would have taken 1.5 lakh or more up front, so the BH owner not only pays less overall but spreads it out, keeping cash in hand in the early years. In a low-tax state the same schedule ends above the lifetime figure, which the chart shows clearly. The point of surfacing the whole schedule is that a road-tax decision made for fourteen years deserves to be seen across all fourteen, not judged on the first payment alone.

Common BH Series Mistakes to Avoid

• Assuming BH is always cheaper. It is a convenience structure. In Gujarat, Himachal or Haryana a normal registration frequently costs less. Always run the break-even for your state.
• Trusting a calculator that omits the 1.25 factor. Several popular tools divide the base tax by 7.5 and call it the two-year figure. That is wrong and understates the tax by a fifth. Confirm any figure against the correct formula.
• Using the ex-showroom or on-road price. The tax base is the invoice value excluding GST, which is lower than on-road and slightly different from ex-showroom. Using the wrong base inflates your estimate.
• Forgetting the renewal. Unlike a one-time lifetime tax, BH must be renewed every two years. A missed renewal means penalties and a technically unroadworthy vehicle.
• Booking the car before confirming eligibility. Private buyers who cannot get Form 60 from their employer cannot register on BH, no matter what the dealer implies. Confirm the certificate first.
• Ignoring the fuel adjustment. Diesel adds two points and can tip BH above your state’s rate, while an EV waiver in your state can beat BH entirely. Model your actual fuel type.

BH Series Myths, Cleared Up

Myth: BH plates are only for the ultra-rich to dodge tax. Not so. BH was designed for mobile employees, and for many of them it is cheaper than repeated re-registration, not a loophole. The scheme is tied to eligible employment, not wealth.

Myth: a BH car cannot be sold. It can. A BH vehicle can be sold like any other, and the buyer’s eligibility and state determine how the registration is handled thereafter. Resale is not blocked by the BH series.

Myth: BH means no road tax at all. BH is still road tax, just paid in two-year blocks under a central formula rather than as a state lifetime lump sum. You pay across the life of the vehicle, and the total can be higher or lower than lifetime depending on your state.

Myth: you can switch your existing car to BH whenever you like. In most states the BH choice is made at first registration and cannot be applied retrospectively. Rules are evolving, so verify the current position rather than assuming conversion is available.

BH vs State Lifetime Tax at Three Price Points

Because the break-even shifts with the price of the car, here is a fuller reference across three common price points for a petrol vehicle, an entry car at 8 lakh, a mid car at 15 lakh, and a premium car at 25 lakh. For each, the BH fourteen-year total is compared with the indicative state lifetime tax. Where BH is lower, it wins on cost as well as convenience, where the state figure is lower, BH only makes sense if you move. As always these state rates are indicative, confirm yours on Vahan.

8 lakh entry car (BH 14-year total about ₹74,667)

15 lakh mid car (BH 14-year total about ₹175,000)

25 lakh premium car (BH 14-year total about ₹350,000)

Indicative representative rates for petrol vehicles. Diesel adds roughly two points to the state figure, EVs are often fully waived. Verify your exact rate on the Vahan portal.

The BH Renewal Process, Step by Step

Because BH is paid in two-year blocks rather than once, renewal is a real part of ownership that a lifetime registration never involves, and getting it wrong is the most common BH headache. The good news is that renewal is straightforward and almost entirely online through the Vahan portal. Here is how it works and what to watch for.

Roughly a month before your current two-year block expires, log in to the Vahan portal with your vehicle details. The system already knows your BH registration and will calculate the next two-year payment using the same MoRTH formula, on the same invoice value, so the amount is predictable, it does not rise with the car’s age the way some owners fear. You pay online, receive a digital receipt, and your registration is extended for the next two years. There is no need to visit the RTO in person for a routine renewal, and no re-inspection of the vehicle for the tax renewal itself, though your separate pollution certificate and insurance must of course stay current.

The one thing to guard against is simply forgetting. Unlike a lifetime tax you paid and never think about again, BH quietly expires every two years, and driving on an expired block is an offence that attracts a penalty and can complicate an insurance claim. Set a calendar reminder for two months before each expiry, or note the renewal date on the same day you diarise your insurance renewal so the two travel together. Over fourteen years you will do this seven times, then move to annual renewals from the fifteenth year. Treat it like insurance, a small recurring admin task, and BH stays painless. Ignore it, and the convenience the series was designed to give you turns into a fine.

Worked Scenario: A Transfer From Pune to Bengaluru

The clearest way to see BH’s value is to follow one family through the exact situation it was built for. Meet Vikram, a private-sector IT manager whose employer has offices in eight states, so he qualifies for BH. In 2026 he buys a petrol car with an invoice value of 12 lakh in Pune. Consider his two possible paths.

Path one, normal Maharashtra registration. Vikram pays Maharashtra its lifetime road tax up front, roughly 12 percent on a 12 lakh car, about 1.44 lakh, and gets an MH plate. Two years later his company transfers him to Bengaluru. Now the clock starts, within twelve months he must re-register in Karnataka and pay Karnataka road tax too, another 13 to 18 percent, call it 1.8 lakh, while applying to Maharashtra for a refund of his unused tax. That refund, calculated on a depreciated basis and delayed by two bureaucracies, might eventually return 60,000 to 80,000 if he is lucky and persistent. Net, Vikram has paid well over 3 lakh in road tax on one car in two states and spent months chasing paperwork.

Path two, BH series. Vikram registers on a BH plate in Pune. His two-year payment on the 12 lakh car in the 10 percent slab is about 20,000. When he moves to Bengaluru two years later, he does nothing at the RTO, his BH plate is already valid in Karnataka. He simply pays his next two-year BH block when it falls due, again about 20,000, from wherever he now lives. Over the fourteen years and the two inter-state moves his career brings, he pays roughly 1.4 lakh in total, spread out, with zero re-registration and zero refund battles. Against path one’s 3 lakh-plus and months of hassle, BH has saved Vikram more than half his road-tax cost and all of the administrative pain. This is the scenario the calculator’s break-even is really pricing, and for a genuinely mobile professional like Vikram, the answer is emphatic.

Notice, though, what would flip it. If Vikram were settled in Pune with no prospect of moving, path one’s single 1.44 lakh payment, with no renewals, would be the simpler and often cheaper choice, and in a low-tax state like Gujarat it would be cheaper still. The scenario only favours BH because Vikram actually moves. That is why the honest question is never just what does BH cost, but will you move, and the calculator answers the cost half so you can weigh it against your own answer to the mobility half.
