E-Way Bill: What It Is, When It's Required and How to Generate It (2026)

If you move goods for your business, whether you sell them, ship them to another branch, or send them back to a supplier, you will run into the e-way bill. It is one of the most misunderstood parts of GST, and getting it wrong can mean your goods are detained at a checkpoint and a penalty is levied. This guide explains what an e-way bill is, when you need one, what goes into it, how long it stays valid, and the exact steps to generate one on the portal.

What an e-way bill is

An e-way bill, short for electronic way bill, is a document generated on the GST e-way bill portal before goods are moved from one place to another. It carries a unique number, called the EBN, and records who is sending the goods, who is receiving them, what the goods are, their value, and how they are being transported. The person moving the goods, or the transporter, must carry this information during transit so an officer can verify it if the vehicle is checked.

The purpose is to give the tax system a live view of goods on the move, which reduces tax evasion and speeds up genuine consignments through checkpoints. It sits alongside your GST invoice, not in place of it: the invoice records the sale, the e-way bill authorises the movement.

When an e-way bill is required

The main trigger is value. An e-way bill is generally required when the value of goods in a single consignment is more than Rs 50,000. This applies not only to sales but to any movement, including a stock transfer between your own godowns, goods sent for job work, and returns to a supplier. The threshold is based on the consignment value including the GST charged.

States can set their own lower thresholds for movement of goods within the state, so a movement under Rs 50,000 may still need a bill in some states. Always confirm your state's rule for intra-state moves rather than assuming the national figure applies everywhere.

Who generates it

The registered person who causes the movement of goods is responsible for generating the e-way bill. In most transactions that is the supplier who raises the invoice. In some cases the recipient generates it, for example when buying from an unregistered person. If a registered person hands the goods to a transporter without generating a bill, the transporter may be required to generate it based on the invoice and details provided. For the vast majority of small businesses, the seller raising the invoice is the one who creates the e-way bill.

Part A and Part B

An e-way bill has two parts, and both matter:

For movement by road, the e-way bill is complete only once Part B is filled with the vehicle number. There are limited situations, such as very short distances within a state as notified, where Part B is not mandatory, but the safe default is to complete both parts.

Validity by distance

An e-way bill does not stay valid forever. Its validity depends on the distance the goods have to travel. As a broad rule, you get roughly one day per 200 kilometres of distance, with proportionate additional time for any leftover distance beyond a full block. So a short local move carries a short validity, while a long inter-state haul carries several days.

The validity is generally counted from the time Part B is entered. If the goods cannot reach the destination within the valid period because of a breakdown or a genuine delay, the person in charge can extend the e-way bill within the window the portal allows, giving a reason. Letting a bill lapse in transit exposes the consignment to detention, so plan the route and the validity together.

Common exemptions

You do not always need an e-way bill. Common cases where one is not required include:

The exempt list and the state notifications change from time to time, so treat these as categories to check rather than a fixed list to rely on. When in doubt, generating a bill is safer than skipping one.

How to generate one on the portal

The process on the e-way bill portal is straightforward once your details are ready:

If your billing tool is linked to the e-way bill system, most of Part A can be pulled straight from the invoice, which cuts re-typing and reduces the small errors, a wrong HSN code or a mismatched value, that cause disputes at checkpoints. Keeping your invoicing and e-way bills in one flow, and your input tax credit records clean, saves time and avoids penalties.

The takeaway

The e-way bill rewards preparation. Know that the usual trigger is a consignment over Rs 50,000, keep Part A and Part B complete, match the validity to the distance, check exemptions and state thresholds before you assume, and generate the bill from your invoice so the details stay consistent. Do that and your goods move through checkpoints without drama. If new rules or rates affect you, keep an eye on updates like the latest GST changes.
