Road tax for national permit trucks: home state vs other states

Fleet owners new to the national permit often ask a fair question: if the truck runs in ten states, which of them does it pay road tax to? The short answer is the home state, plus an authorisation fee that covers the rest. The details are worth knowing, because both have dates, and both can lapse.

Road tax is a state tax

Road tax on motor vehicles is charged by each state under its own motor vehicles taxation act. For goods vehicles, it is commonly paid quarterly or annually, though some states charge lighter goods vehicles a one-time tax at registration instead. The rates, slabs and the way tax is calculated differ from state to state, and change with state budgets and notifications.

A truck pays road tax to the state where it is registered. The date the tax is paid up to is recorded on the vehicle's VAHAN record.

Where the national permit comes in

Without a national permit, a goods vehicle on a home-state permit that enters another state needs that state's permission, through a counter-signature or temporary permit, and can face that state's charges. The national permit scheme replaced that with a single arrangement: the home state issues the permit, and the truck pays an annual national permit authorisation fee online through Parivahan. The authorisation is what makes the permit valid across the country.

So a national permit truck has two separate payments to keep current:

Neither replaces the other. Paying the authorisation does not pay the home state's tax, and paying the tax does not renew the authorisation.

What goes wrong

• Tax lapses quietly. Quarterly tax comes round four times a year per truck. For a 60-truck fleet that is 240 payments a year, each on its own date.
• Tax and authorisation get confused. Someone pays one and believes the truck is covered.
• Grace periods differ. Some states allow a short period after the tax falls due; others charge a penalty from the first day. Assuming the rule from one state applies in another is a common mistake when a fleet registers trucks in more than one state.
• Rates change. A payment made at last year's rate after a revision can leave a shortfall.

Fleets with trucks in several states

Fleets that buy second-hand trucks, or run branches, often have vehicles registered in two or three states. Each pays tax to its own home state, under that state's act, on that state's schedule. Our state rules pages describe how each of twelve states structures goods vehicle tax and where its current notification is published.

A routine that works

1. Read the tax-paid-up date for every truck from the vehicle record.
2. Record the payment period for each truck: quarterly, half-yearly or annual.
3. Record the authorisation date separately.
4. Set reminders 30, 15, 7 and 1 days before each, to the person who pays.
5. After each payment, check the new paid-up date shows on the record.

Selling, moving or resting a truck

Three situations catch fleets out. When a truck is sold, the tax position goes with the vehicle, and a buyer will want the tax paid up to date before the transfer goes through. When a truck is moved to another state for good, it is re-registered there and starts paying that state's tax, and the old state may refund unused tax on application, depending on its rules. When a truck is laid up for repairs or a slack season, several states allow a non-use declaration that suspends the tax for that period, but the declaration usually has to be filed before the period starts, not after.

In every one of these cases, the rule is the home state's, not a national one. Read the state's notification, or ask the RTO, before relying on what worked in another state.

Where PRACHSO fits

PRACHSO reads the tax-paid-up date and the permit details from each truck's record and keeps road tax and the national permit authorisation as separate dates. Each has its own reminders on WhatsApp to whoever pays. PRACHSO does not pay tax or fees on anyone's behalf: it pre-fills what it can and hands off to the official portal.
