Quick answer: If you've brought your vehicle to Bangalore from another state, you have 30 days to update your address with the local RTO, and a hard 12-month deadline from the date your vehicle entered Karnataka to complete full re-registration with a new local number. Miss that 12-month window and your original registration becomes invalid, with real penalties and the risk of the vehicle being seized. The one way around this entirely is a BH (Bharat) series number plate, if you're eligible for one, which avoids re-registration altogether when you move states.

The 30-Day and 12-Month Rules

Under the Karnataka Motor Vehicles Act, there are actually two separate clocks running once your vehicle enters the state:

• 30 days to update your address on the vehicle's registration, even before you re-register it with a new number
• 12 months from the date of entry to complete full re-registration, obtain a No Objection Certificate (NOC) from your original state, and get a new Karnataka registration number

Your vehicle can legally run on its original state's number for up to that 12-month window. After that, if you haven't re-registered, the original registration becomes invalid, and the vehicle is technically at risk of being seized.

The BH Series Exception

If you're eligible for a BH (Bharat) series number plate, none of the above applies to you. BH registration is specifically designed for people with transferable jobs, and it means you never have to re-register or get an NOC when you move states.

• Who's eligible: central and state government employees, defence and armed forces personnel, employees of PSUs and banks, and private-sector employees whose company has offices across multiple states (the typical threshold cited is four or more states, confirm the current figure with your RTO or the Vahan portal)
• What you get instead: no re-registration or NOC requirement when you move, road tax paid in two-year blocks rather than one lump sum, and simpler resale across states
• How to switch: for a new vehicle, ask your dealer for BH registration at the time of purchase; for an existing vehicle, eligible owners can convert through the Vahan portal or their RTO

If you think you might qualify, it's worth checking before you go through the standard re-registration process below, since it can save you the entire exercise on this vehicle and any future one.

The Re-Registration Process

If BH registration doesn't apply to you, here's the sequence:

• In your original state: get a police verification report from your hometown police station, and apply for an NOC (CMV Form 28, in quadruplicate) from your original RTO
• In Karnataka: apply at your local RTO with the NOC, the registration mark application (Form 27), the change of address form (Form 33), the migration intimation form (KMV Form 27), and a police verification report (SCRB), obtainable locally for a small fee
• Pay the Lifetime Tax (LTT) applicable in Karnataka and get the corresponding tax form (KMV 14)

If your NOC from the original state doesn't arrive within 30 days of applying, you can proceed in Karnataka using a copy of your Form 28 application, proof you submitted it, and a declaration that no response was received.

Documents You'll Need

• NOC from your original state's RTO (Form 28)
• Registration mark application, change of address, and migration intimation forms
• Police verification (SCRB) report
• Original purchase invoice
• Identity and current address proof
• RC book, insurance, and PUC (Pollution Under Control) certificate
• Financier's consent letter, if the vehicle is under a loan
• Passport-size photographs

Tax, Fees, and Claiming a Refund

Karnataka's Lifetime Tax depends on your vehicle's invoice value and age, vehicles under two years old are treated as new for this purpose. Once your new Karnataka number is issued, you can separately claim a refund of the Lifetime Tax you already paid in your original state, and claiming it sooner generally gets you a larger refund than waiting.

What Happens If You Miss the Deadline

Failing to re-register within 12 months carries a penalty, typically starting around a few hundred rupees for a first offence and more for repeat non-compliance, on top of any unpaid tax plus interest. If you've already applied and are waiting on paperwork, keeping your RTO acknowledgement on hand is useful if you're stopped, since it shows you've started the process rather than ignored it.

Where DocuPro Fits In

DocuPro handles the full re-registration process for vehicles moving into Bangalore: coordinating the NOC from your original state, filing the Karnataka-side forms, managing the tax payment, and following up until your new registration is issued, so you're not tracking down forms across two states' RTOs yourself.

We won't promise the RTO moves faster because of who files the paperwork, that depends on the office's workload either way. What we take off your hands is making sure nothing in a two-state process gets missed, so you're not the one finding out at the 11-month mark that a form was never submitted.

Frequently Asked Questions

1. How long can I drive my vehicle in Bangalore with my old state's number plate?

Up to 12 months from the date it entered Karnataka, provided you address the required address update within the first 30 days.

2. What happens if I don't re-register within 12 months?

Your original registration becomes invalid, you can face a penalty plus unpaid tax and interest, and the vehicle is technically at risk of being seized.

3. Can I avoid re-registration entirely?

Yes, if you're eligible for a BH (Bharat) series number plate, typically available to those with transferable government, defence, PSU, bank, or qualifying private-sector jobs. BH-registered vehicles don't need re-registration or an NOC when you move states.

4. What documents do I need from my original state?

An NOC (CMV Form 28) from your original RTO, along with a police verification report from your hometown police station.

5. Do I get my old state's road tax back after re-registering in Karnataka?

Yes, you can claim a refund of the Lifetime Tax already paid in your original state once your new Karnataka registration is issued. Claiming sooner tends to get a larger refund.

6. What if my NOC doesn't arrive in time?

If 30 days pass with no response, you can proceed using a copy of your application, proof of submission, and a declaration that no reply was received.

7. Does the 12-month rule apply to two-wheelers too?

Yes, the same re-registration requirement applies to both two-wheelers and four-wheelers brought into Karnataka from another state.
