E-Way Bill Rules: When Required, Validity & Penalties

The e-way bill is the single most operationally disruptive GST compliance requirement for businesses that move physical goods, because a mistake here does not just create a paperwork problem later; it stops a truck on the highway right now. Most disputes we see are not about whether the rule exists, but about the details: exact thresholds, how validity is calculated, and what counts as a valid reason for an extension.

When Is an E-Way Bill Required?

An e-way bill (Form GST EWB-01) must be generated before goods worth more than Rs 50,000 (inclusive of tax) are moved by road, rail, air, or vessel. This applies to inter-state movement across the board. For movement within the same state, the Rs 50,000 threshold applies in most states, but a number of states have notified their own, sometimes different, intra-state threshold. Always check the applicable state notification before assuming the national figure applies to a purely intra-state consignment.

The requirement is not limited to sales. It also covers movement for job work, branch transfers, exhibitions, and returns of goods, provided the value crosses the threshold. Certain categories, such as specified exempted goods and movement by non-motorised conveyance, are excluded regardless of value.

How Validity Is Calculated

Once generated, an e-way bill is valid for:

• One day for every 200 km (or part thereof) for normal cargo
• One day for every 20 km (or part thereof) for over-dimensional cargo

Validity starts from the date and time the e-way bill is generated. A consignment travelling 350 km, for example, gets 2 days of validity, not 1.75 rounded down; any part of the distance slab counts as a full additional day. This is the detail that trips up businesses estimating validity manually instead of letting the portal calculate it.

Extending an Expired or Expiring E-Way Bill

If a consignment is delayed, either the generator or the transporter can request an extension through the e-way bill portal, but only within a narrow window: 8 hours before or after the current validity expires. The system requires a reason (traffic delay, vehicle breakdown, natural calamity, and similar categories are typically accepted) and, in some cases, the current location of the goods.

Extensions can be granted in successive stages as needed, but the cumulative extended validity cannot exceed 360 days from the date the e-way bill was first generated. Beyond that, a fresh e-way bill has to be generated against the original document, assuming it is still within the 180-day base-document limit discussed below.

The 180-Day Rule for Base Documents

An e-way bill cannot be generated if the underlying document, the tax invoice, bill of supply, or delivery challan, is more than 180 days old from its own date. This closes a gap where an old, stale invoice could otherwise be used to justify a movement of goods long after the transaction it relates to. In practice, this means businesses with a backlog of undispatched, invoiced stock need to either move the goods promptly or re-invoice before the 180-day window lapses.

Penalties for Non-Compliance

Transporting goods above the threshold without a valid e-way bill, or with an expired, incorrect, or mismatched one, exposes the consignment to detention and seizure of both the goods and the vehicle by GST enforcement officers, along with a monetary penalty. Beyond the immediate financial hit, a detained shipment usually means missed delivery commitments, demurrage costs, and, if it happens repeatedly, closer scrutiny of the business's broader GST compliance. For most businesses moving goods regularly, the practical fix is to build e-way bill generation into the dispatch workflow itself rather than treating it as a separate compliance task done after the fact.

Common Mistakes We See

• Splitting invoices to stay under Rs 50,000: Artificially breaking a single consignment into multiple invoices to avoid the threshold is treated as an attempt to evade the requirement and invites penalty on the full consignment value.
• Vehicle number mismatches: The vehicle number on the e-way bill must match the vehicle actually carrying the goods; a mismatch during a transit check is one of the most common reasons for detention.
• Ignoring intra-state state-specific thresholds: Businesses operating across multiple states sometimes apply one state's threshold everywhere, missing a stricter requirement in another.
• Letting validity lapse mid-transit without extending: Once the 8-hour extension window closes, there is no way to extend that specific e-way bill; a fresh one is needed, which can delay the shipment further.
