For retailers, distributors, wholesalers, and manufacturers, understanding E-Way Bill Rule 138 is essential. Non-compliance can lead to penalties, delays in transportation, and disruption of business operations. Fortunately, modern GST Billing Software can automate most of these compliance requirements.
In this article, let’s understand Rule 138, when an e-Way Bill is required, and how businesses can stay GST compliant.
What is E-Way Bill Rule 138?
Rule 138 of the Central Goods and Services Tax (CGST) Rules, 2017, governs the generation of an e-Way Bill for the movement of goods. It requires registered persons to generate an electronic document before transporting goods when the consignment value exceeds the prescribed limit.
A standard e-way bill contains;
- Supplier
- Recipient
- Goods being transported
- Invoice or delivery challan
- Vehicle details
- Transporter information
Its primary objective is to ensure transparent movement of goods and prevent tax evasion.
When is an e-way bill required under Rule 138?
An e-way bill is generally required when the value of goods exceeds Rs. 50 thousand. It applies in situations like;
- Supply of goods
- Transfer of stock
- Job work
- Return of goods
- Exhibition or business-related movement
- Imports from ports to business premises
The responsibility for generating the e-way bill depends on who initiates the movement of goods.
Who can generate an e-way bill?
Rule 138 allows different parties to generate the e-way bill depending on the transaction. These include;
- Registered supplier and recipient
- Transporter
- E-commerce operator (where applicable)
- Unregistered supplier in certain cases
The document is generated electronically through the GST portal or integrated GST Billing Software
What information is necessary to generate an e-way bill?
Generating an e-way bill requires accurate transaction details. Common information for e-invoice are;
- GSTIN of supplier
- GSTIN of recipient
- Invoice number and date
- HSN code
- Description of goods
- Quantity
- Taxable value
- Vehicle number
- Transporter ID
- Place of dispatch and delivery
Using an integrated ERP System like Marg Billing Software helps populate these details automatically, reducing manual errors.
What are Part A and Part B of an e-way invoice?
An e-Way Bill consists of two important sections Part A and Part B. Let’s explore their components in the table below.
| Part A (Transaction Details) | Part B (Transportation Details) |
| GSTIN of Supplier | Vehicle Number |
| GSTIN of Recipient | Transport Document Number |
| Invoice Details | Transporter Information |
| Value of Goods | |
| HSN Code | |
| Reason for Transportation |
Both sections must be completed before goods are dispatched. For error-free invoicing, we recommend choosing the best GST billing software in India with regular updates and latest features.
What is the validity of an e-way bill?
The validity of an e-way bill depends on the distance to be travelled and the cargo type. Here is core information you need to know for a seamless business.
Validity Rules by Distance
- Normal Cargo: 1 day for up to 200 km, plus 1 extra day for every additional 200 km or part thereof.
- Over-Dimensional Cargo (ODC): 1 day for up to 20 km, plus 1 extra day for every additional 20 km or part thereof.
- Calculation Start: The period counts from the exact date and time the Official E-Way Bill Portal generates the bill.
Extension of Validity
- Time Window: Businesses can extend the validity within 8 hours before or 8 hours after the current expiry time.
- Reasons Required: You must provide a valid reason like a vehicle breakdown, traffic delay, or natural problem when logging into the portal to update vehicle and distance detail.
What happens if Rule 138 is now followed?
Failure to comply with Rule 138 may result in enforcement action under GST. Possible consequences include;
- Detention of goods
- Detention of vehicles
- Financial penalties
- Delayed deliveries
- Additional documentation requirements
