ARN (Application Reference Number) & Its Usage in GST Registration

With the growing complexity of the Indian economy, the government has introduced a very efficient and comprehensive taxation system for goods and services in the country called GST, or Goods and Services Tax. This revolutionary system has replaced many previous indirect taxes, and today, everything from registration to return filing to refunds or tax payments is made online on the GST Portal. As a result, the ARN or Application Reference Number (ARN) plays a critical role in GST's online functionalities.

When you successfully apply for GST Registration, an Application Reference Number (ARN) is automatically generated. This unique number is a crucial part of the GST system, serving as valid proof of your registration application until the Goods and Services Tax Identification Number (GSTIN) is issued.

This article will give more detailed information like the ARN full form in GST, what ARN leverages in the GST system, its importance, and how you can understand the GST ARN status. Read on to learn more on ARN: 

What is Application Reference Number in simplest terms?

The Application Reference Number (ARN) is a unique 15-digit alphanumeric code allotted to each GST registration application. It serves as a reference and identification number throughout the application process until the issuance of the GSTIN. It is also a temporary ID that helps you track the progress of your registration application on the GST Portal.

How is ARN generated, and how long does it take?

The GST Portal automatically creates an ARN with the submission of a GST registration application. When the application is effectively filed, the system allots a unique ARN to it. This number acts as a reference for any subsequent inquiries or clarifications associated with the application. The ARN is usually available instantly or within a short span of time after submitting the GST registration application.

What are the features of ARN?

One of the main features of the Application Reference Number in GST is the input tax credit mechanism. The GST system allows businesses to claim an input tax credit (ITC) on the GST paid on their sales. This prevents cascading taxes and warrants that they are levied only on the value added on the stages of production or distribution. So, by claiming ITC, the tax liability can be reduced for businesses, eventually benefiting the end consumer. However, businesses must adhere to the prescribed time limits for claiming ITC to ensure compliance with GST regulations.

What are the benefits of ARN?

ARN is the key to your GST journey. A confirmed ARN provides transparency about the application status, making it more efficient.

These registrations include Sole Proprietorship, One-Person Company, Partnership Firm, Limited Liability Partnership (LLP) Company, Private Limited Company, Public Limited Company, and Section 8 Company. The GST ARN (Application Reference Number) status specifies the phase of processing an application. Knowing about the different types of company registration in India will help you make the right choice for your business. 

What are the steps involved in generating ARN?

  • Application completion: With the complete application and all mandatory details filled, the applicant submits the form online.
  • Automatic Generation of ARN: With the completion of submission of the GST registration application, the GST portal automatically generates an Application Reference Number (ARN) 
  • Receipt of ARN: The ARN is sent to the applicant via email, or you can also note it down directly from the GST portal immediately after submitting your GST application.
  • Tracking with ARN: The ARN number is very important as it allows the GST certificate applicant to track the status of the GST registration application on the GST Portal till the final GSTIN (Goods and Services Tax Identification Number) are issued by the government. 

Can you describe the Procedure for checking GST registration application status using ARN?

Once you have logged in to the GST Portal, you can track the status of various applications like new registrations, amendments, or cancellations. Here is a step by step know how to explain the procedure to check the application status using the GST portal:

The GST process must become simpler and less intimidating as it empowers taxpayers, maintains clarity, and fosters efficiency.
