e-Invoicing under Goods and Services Tax Laws

E-Invoicing under Goods and Services Tax is a way of electronically authenticating business-to-business ( B2B ) invoices. If your business falls under certain categories, you’re required to generate e-invoices for B2B transactions.

In simple terms, under Goods and Services Tax rules, an “invoice” or “tax invoice” is a document required by the Goods and Services Tax Act, 2017. This law says that anyone selling goods or services must provide an invoice or a bill of supply for each transaction. Issuing an invoice is necessary for people involved in selling goods or services.

An Overview of the Goods and Services Tax Invoice Registration Portal (IRP)

The Invoice Registration Portal ( IRP ) is like a website where businesses upload their invoice details. It quickly generates a unique code for each invoice and puts it in a QR code. This code helps track the invoice easily. The IRP also works with other government systems to make filing taxes and generating transport documents easier for businesses. It’s managed by the government’s NIC and provides all necessary information on its interface.

Notification number 69/2019 – Central Tax, dated December 13, 2019, was issued to announce ten website addresses for registering invoices according to rule 48(4). The first Invoice Registration Portal ( IRP ) has been active for the past two years and is accessible at “https://einvoice1.Goods and Services”. This portal is managed by the National Informatics Centre ( NIC ) and more taxpayers are being included under the ‘e-invoice’ rule. Another portal, “https://einvoice2Goods and Services”, has been set up by NIC to ensure continuous operation 24/7. Additionally, four new IRPs have been introduced by private companies, offering unique value-added services.

The Goods and Services Tax e-invoicing Process: A step-by-step Guide:

Setting Up E-Invoicing

To initiate e-invoicing, businesses must ensure their ERP system aligns with PEPPOL standards, incorporating prescribed e-invoicing standards and mandatory parameters from CBIC.

Creating Invoices

Upon technical setup completion, businesses generate regular invoices on their software, incorporating essential details like billing information, Goods and Services TaxN, transaction value, item rate, Goods and Services Tax rate, and tax amount.

Uploading to IRP and Authentication

The invoice details, especially mandatory fields, are then uploaded to the Invoice Registration Portal ( IRP ). The IRP authenticates B2B invoice details, checks for duplications, and generates an Invoice Reference Number ( IRN ).

Integration with Goods and Services Tax and E-Way Bill Portals

The authenticated payload is sent to the Goods and Services Tax portal for returns, and relevant details are forwarded to the e-way bill portal if applicable. The Goods and Services TaxR-1 of the seller is auto-populated, determining their tax liability.

Advantages of e – invocing through Goods and Services TaxN

1. Error Reduction: Fixes errors in data reconciliation, reducing mistakes.

2. Interoperability: Invoices from one software are easily understood by another, minimizing data entry errors.

3. Real-Time Tracking: Enables real-time monitoring of supplier invoices.

4. Automation of Goods and Services Tax Return Filing:Streamlines the process with invoice details automatically populating returns.

5. Quick Access to Input Tax Credit:Facilitates quicker access to genuine input tax credit.

6. Audit Reduction: Decreases the chance of tax audits as required information is available at a transaction level.

7. Access to Formal Credit Routes: Enhances opportunities for invoice discounting or financing, especially for small businesses.

8. Improved Business Relations: Small businesses can strengthen customer relations and explore opportunities with larger enterprises.

Required Documents for E-Invoicing –

Businesses need to report invoices, credit notes, debit notes under section 34 of the Central Goods and Services Tax and other documents specified under Goods and Services Tax law as e-invoices.

If your business’s sales exceeded a certain limit between 2017-18 and 2021-22, or if it goes beyond that limit in the current financial year, you need to use e-invoicing from the next financial year (starting FY 2023-24). This rule applies if the combined sales of all your Goods and Services Tax numbers under one PAN in India surpass the specified limit.

E-Invoicing under Goods and Services Tax is akin to upgrading from handwritten letters to instant messaging for businesses. Recent updates and added features highlight continuous improvements, making the invoicing process more efficient and error-free in the digital age. It’s not just about staying current; it’s about enhancing business operations and collaboration opportunities.

The Limit to upload invoice for IRN.

Under Goods and Services Tax law, there’s no extra time given to upload invoice data for IRN generation. The rules state that certain registered persons need to prepare invoices using specific details in Form Goods and Services Tax INV-01 and get an IRN by uploading it on the common portal. Any invoice issued differently won’t be considered valid. Also, a QR code with IRN is mandatory for invoices issued by certain notified persons. Additionally, Part A of the e-way bill is generated automatically based on the invoice data uploaded.

Sure, here are the rules outlined in bullet points:

– Rule 48(4): Certain registered persons must prepare invoices using specific details in Form Goods and Services Tax INV-01 and obtain an IRN by uploading it on the common portal.

– Rule 48(5): Invoices issued in any other manner than specified in Rule 48(4) will not be considered valid.

– Rule 46(r): A QR code embedded with IRN is mandatory for invoices issued by notified persons under Rule 48(4).

– Rule 138A(3): Part A of the e-way bill is generated only based on the invoice data uploaded at IRP.

All the rules mentioned indicate that for notified persons under Rule 48(4), invoices must strictly follow the guidelines set in Rule 48(4). It’s important to ensure that the data on the invoice document matches the data of the IRN, especially when transitioning between months or years.

An advisory from Goods and Services TaxN stated that starting from May 1, 2023, a 7-day time limit was set for uploading old invoices for entities with an Annual Aggregate Turnover ( AATO ) over ₹100 Crore. However, this 7-day time limit was deferred for three months as informed by Goods and Services TaxN.

Additionally, as a one-time measure, a grace period of 30 days was allowed to obtain IRN for invoices issued between October 1, 2020, and October 31, 2020, as per Notification 73/2020 dated October 1, 2020.

Sure, here it is in a more expanded form:

How e-invoicing records / documents are Secured and Saved:

Rule 57 states that it’s necessary to keep electronic backups of e-invoice records in good order and store them securely as outlined. These backups should be readily accessible if requested by the Goods and Services Tax Proper Officer. Furthermore, Section 36 specifies the requirement to retain documents and records for a period of 72 months, which equals six years.

Using QR Codes for Invoices

What is a QR Code?

– A two-dimensional code for machine readability.

– Contains invoice details such as supplier and recipient Goods and Services TaxIN, invoice number, date, value, line items, HSN code, and a unique IRN or hash.


– All B2B taxpayers generating invoices must print the QR code on their invoices as per e-invoice schema mandated by the Goods and Services Tax Council.
