GST and Udyam Registration serve different purposes for a business. GST is India’s indirect tax system, while Udyam Registration provides official recognition to eligible Micro, Small and Medium Enterprises (MSMEs). Where GSTIN information is applicable to an enterprise’s Udyam records, keeping the details accurate helps maintain consistency across government records and supports smoother verification and compliance.The Udyam Registration portal uses PAN and GST-linked information from government databases for applicable enterprises. Therefore, businesses should regularly verify their GSTIN, PAN, turnover and enterprise details and update the relevant records whenever changes occur.
Because of all this, it becomes essential to keep GST and Udyam records accurate and up to date. This helps meet regulatory requirements, strengthens corporate credibility, and helps you avoid annoying issues during verification or when dealing with government authorities. Companies that link and then periodically update both registrations can speed up compliance, improve their legal position, and still focus on steady growth while making use of what India’s MSME ecosystem offers.
Quick Summary
Keeping GSTIN and Udyam Registration details consistent is important for eligible MSMEs that are required to provide GST information under the applicable rules. The Udyam portal uses PAN and GST-linked information from government databases for enterprise classification and verification where applicable. Businesses should therefore ensure that their GSTIN, PAN and enterprise details are accurate and updated across the relevant government records.

What is GST?
The Goods and Services Tax (GST) is a unified indirect tax introduced in India on 1 July 2017 under the CGST Act, IGST Act, and State GST Acts. It replaced multiple indirect taxes, such as VAT, service tax, and excise duty, with a single tax system applicable to the supply of goods and services across the country. Businesses registered under GST can claim Input Tax Credit (ITC) on eligible purchases, reducing the overall tax burden. Eligible businesses must complete GST registration online to comply with tax laws, collect GST legally, and avail themselves of the benefits of the GST framework.

What is Udyam Registration?
Udyam Registration is an online scheme developed by the Ministry of Micro, Small & Medium Enterprises (MSME), Government of India, to register MSMEs. This scheme has replaced the previous scheme of Udyog Aadhaar and offers a unique identification number and an e-certificate called the Udyam Registration Certificate to the enterprises.
Through this scheme, the eligible enterprises get recognised officially as MSMEs, thus becoming eligible for various schemes offered by the government like subsidies, incentives, priority sector loans, etc. The scheme works in a completely paperless manner, uses the system of self-declaration, and is linked with the Aadhaar, PAN, and GST databases. Business entities having investments and turnovers meeting the required conditions can register under the Udyam Registration Scheme on the official website.
For a complete guide on how to register under the Udyam scheme and the benefits it provides to e-commerce businesses, see our guide on MSME registration for e-commerce sellers and D2C brands.
GST Registration vs Udyam Registration
GST Registration and Udyam Registration are two different registrations with different purposes. GST registration is related to indirect tax compliance and applies when a business becomes liable under GST law or falls within a compulsory registration category. Udyam Registration identifies an eligible enterprise as a Micro, Small or Medium Enterprise under the MSME framework.
A business may therefore have GST registration without necessarily being an MSME, while an eligible MSME may not always need GST registration if it falls within an applicable exemption. The requirement to provide GSTIN information for Udyam purposes depends on the applicable GST and MSME rules.
Is GST Linking Mandatory for All Udyam Registrations?
No — it depends on whether your business is required to register for GST:
| Business Type | GST Registration Required? | GST-Udyam Linking Required? |
| Turnover below ₹40 lakh (goods, most states) | No | No |
| Turnover below ₹20 lakh (services, most states) | No | No |
| Selling through e-commerce platforms | Yes — regardless of turnover | Yes |
| Export-oriented businesses | Yes | Yes |
| Turnover above GST threshold | Yes | Yes |
| Businesses in special category states (lower threshold) | Yes above ₹10 lakh | Yes |
Businesses below GST registration thresholds can complete Udyam Registration without providing a GSTIN, and this is entirely valid. The requirement to link a GSTIN applies only to businesses that are legally obligated to hold a GST registration.
Steps to Link GST With Udyam Registration
Exact Portal Navigation for Linking GST With Udyam
| Step | Action | URL/Location |
| 1 | Go to the official Udyam portal | udyamregistration.gov.in |
| 2 | Click “Update Details” or “For those already registered” | Homepage menu |
| 3 | Enter Udyam Registration Number (URN) | Format: UDYAM-XX-00-0000000 |
| 4 | Verify with Aadhaar OTP on registered mobile | OTP-based authentication |
| 5 | Navigate to the “Enterprise Details” section | Left menu after login |
| 6 | Find the GSTIN field — enter your 15-digit GSTIN | Enterprise details tab |
| 7 | Portal auto-fetches business name, address, and turnover from the GST system | Verify auto-populated data |
| 8 | Submit and download the updated certificate | Confirmation page |
Important: The Udyam portal may require authentication using the details associated with the existing registration. Before attempting an update, verify that your GSTIN, PAN and business information are correct. If your GST details are not reflected in Udyam Registration, first identify whether the mismatch originates from the GST record or the Udyam record before submitting another update.
What Happens If GST and Udyam Details Do Not Match?
A mismatch between GST and Udyam information does not automatically mean that a business has committed a GST offence. However, incorrect or outdated information can create difficulties during verification, classification, amendments or applications connected with government schemes.
Common issues include:
- GSTIN not appearing correctly in Udyam records
- Differences in PAN or legal business name
- Outdated business information
- Incorrect turnover or enterprise details
- Difficulty verifying MSME information for a particular purpose
If the information submitted during Udyam registration or updation is intentionally misrepresented or suppressed, the enterprise may be subject to the applicable penalty provisions under Section 27 of the MSMED Act. Kanakkupillai supports businesses with GST registration, GST amendments, Udyam Registration, record updates and ongoing GST and MSME compliance requirements.
Advantages of Linking GST With Udyam Registration
Linking GST with Udyam Registration helps the Micro, Small, and Medium Enterprises (MSMEs) with various benefits like improved compliance and accurate business documentation. Some of the main advantages are:
- Effective Verification: Records from GST can help in verifying the authenticity of the information shared during Udyam Registration.
- Accurate Turnover Information: Through GST records, the Udyam portal reduces the need for manual data entry by fetching the turnover information.
- Easier Compliance:Keeping GST and Udyam information consistent becomes particularly important when business particulars change. If your business information has changed, first complete the required GST registration amendment and then verify whether the corresponding Udyam information also needs to be updated.
- Quick Access to MSME Benefits: Correctly linked records help to process the benefits from various government schemes, incentives, subsidies, and credits efficiently.
- Less Documentation: The automatic linkage of information from GST will reduce the submission of extra documents.
- Enhanced Accuracy: Linked records make the commercial information shared by businesses more reliable.
- Easily Updatable Records: Any changes in the business can be easily updated through this linkage.
- Improved Credibility: Accurate and up-to-date registrations increase the credibility of the company with banks, financial institutions, government departments, and business partners.
How Udyam Registration Relates to Section 43B(h) for MSME Suppliers
Udyam Registration can be important for businesses that qualify as micro or small enterprises because MSME status is relevant to the delayed-payment framework under the MSMED Act.
Under Section 15 of the MSMED Act, where payment terms are agreed in writing, the agreed period cannot exceed 45 days from the date of acceptance or deemed acceptance. Section 43B(h) of the Income Tax Act provides that certain amounts payable by an assessee to a micro or small enterprise beyond the period specified under Section 15 are allowed as a deduction only on actual payment. Therefore, businesses should maintain accurate Udyam and supplier records. However, GST-Udyam linking itself should not be described as creating the Section 43B(h) liability. Certain companies are required to file MSME Form 1 with the Registrar of Companies when applicable, particularly where payments due to micro or small enterprise suppliers remain outstanding beyond the prescribed period. The filing requirement depends on the applicable Companies Act provisions and the company’s circumstances.
