PAN Card is one of the most important requirements when applying for GST registration in India. The GST registration application uses the PAN of the business or the proprietor, depending on the constitution of the business. The GST Portal specifically states that PAN is mandatory for GST registration and that the legal name of the business should be entered as it appears in the PAN database.
For businesses planning to obtain a GSTIN in 2026, understanding which PAN should be used is important because the requirement is different for a proprietorship, partnership firm, LLP, company and other types of entities. A personal PAN may be relevant for a sole proprietor, while a separate entity PAN is applicable to businesses that have their own legal identity.
The PAN and GST registration details should also be entered carefully because the GST system validates the constitution of the business against the PAN information. A mismatch in the legal name, PAN or business constitution can create verification issues during registration.
The Income Tax framework has also moved to the new PAN forms from 1 April 2026. However, existing PAN numbers continue to remain valid, so businesses do not need to obtain a new PAN simply because the PAN application forms have changed.
What Is PAN Card for GST Registration?
PAN for GST registration means the Permanent Account Number that identifies the taxpayer or business whose GST registration is being requested.
While applying for GST registration, the applicant has to provide the appropriate PAN in the registration application. The GST Portal requires the PAN of the business or the PAN of the proprietor, depending on the business structure.
The PAN is not the same as the GSTIN.
PAN is an income-tax identification number, whereas GSTIN is the identification number issued after successful GST registration.
A simple distinction is:
| Particular | PAN | GSTIN |
|---|---|---|
| Full Form | Permanent Account Number | Goods and Services Tax Identification Number |
| Main purpose | Taxpayer identification | GST registration identification |
| Issuing authority | Income Tax Department | GST authorities |
| Used for | Income-tax and specified financial activities | GST returns, invoices and GST compliance |
| Relationship | Used during GST registration | Generated after GST registration |
Therefore, obtaining a PAN does not automatically provide a GSTIN. A separate GST registration application is required when registration is applicable.
Is PAN Mandatory for GST Registration?
Yes. PAN is mandatory for GST registration.
The GST Portal’s registration instructions specifically state that applicants must provide the PAN of the business or proprietor and that PAN is mandatory for GST registration.
The PAN requirement also helps the GST system identify the correct taxable person and validate information provided in the application.
During the initial registration process, the applicant has to provide:
- State or Union Territory
- District
- Legal name of business as mentioned in PAN
- PAN of business or proprietor
- Email address of the primary authorised signatory
- Mobile number of the primary authorised signatory
Email and mobile verification is carried out through OTP during the registration process.
Which PAN Is Required for GST Registration?
The correct PAN depends on the constitution of the business.
Sole Proprietorship
A sole proprietorship generally uses the proprietor’s PAN for GST registration.
The proprietor and the proprietorship do not have separate PAN identities in the same way that a company and its director do.
Therefore, if an individual operates a business as a proprietorship, the proprietor’s PAN is generally the PAN used for GST registration.
Partnership Firm
A partnership firm can have its own PAN.
Where the partnership firm is the taxable person applying for GST registration, the firm’s PAN should be used rather than the personal PAN of an individual partner.
The PAN information should correspond with the legal name and constitution of the partnership.
Limited Liability Partnership
An LLP has its own legal identity and can have its own PAN.
For GST registration of an LLP, the LLP’s PAN is used as applicable.
The personal PAN of a partner should not be substituted for the LLP’s PAN when the GST application requires the entity’s PAN.
Private Limited Company
A private limited company has its own PAN.
When the company applies for GST registration, the company’s PAN is used for the business registration.
The PAN of a director or shareholder may be required separately in authorised-signatory or stakeholder information, but it does not replace the company’s PAN.
Public Limited Company
A public limited company similarly uses its own entity PAN for GST registration.
The company’s legal name and PAN details should correspond with the information recorded in the relevant databases.
Other Business Structures
Trusts, societies, associations and other eligible organisations may have different documentation and registration requirements.
The applicant should identify the correct constitution before starting the GST application and use the corresponding PAN.
PAN and Legal Name in GST Registration
One of the most important details in the GST application is the legal name.
The GST Portal instructs applicants to enter the legal name of the business as mentioned in the PAN database. The trade name is a separate field and can be different from the legal name.
For example, a business may operate publicly under a brand or trade name while its legal name is associated with the proprietor or registered entity.
The applicant should therefore distinguish between:
- Legal name
- Trade name
- PAN
- Business constitution
- GST registration details
Using the trade name where the portal asks for the PAN-based legal name can result in incorrect information.
PAN and GSTIN: What Is the Difference?
PAN and GSTIN are connected but serve different purposes.
PAN identifies the taxpayer for income-tax purposes and certain other financial and regulatory activities.
GSTIN identifies a taxpayer registered under the GST system.
After a successful GST registration, the GSTIN is issued according to the applicable registration details.
Businesses should therefore avoid treating PAN and GSTIN as interchangeable numbers.
The PAN is required before the GST registration can be completed, while the GSTIN is the registration identification that results from the GST process.
How to Apply for PAN Before GST Registration
If a business does not yet have the required PAN, the PAN should be obtained before proceeding with GST registration.
The process depends on the applicant.
Step 1: Identify the Applicant
Determine whether the applicant is:
- An individual proprietor
- A partnership firm
- An LLP
- A company
- A trust
- Another eligible organisation
This determines whose PAN should be used.
Step 2: Check Existing PAN
Before submitting a new PAN application, check whether the individual or entity already has a PAN.
A second PAN should not be obtained merely because the existing PAN card has been misplaced or because the PAN application forms changed in 2026.
The Income Tax Department confirms that existing PAN numbers continue to remain valid under the new framework.
Step 3: Select the Applicable PAN Process
For new PAN applications filed from 1 April 2026, the applicable forms prescribed under the Income Tax Rules, 2026 are used. The appropriate form depends on the applicant’s category.
Step 4: Enter Correct Business Details
Provide the legal information exactly according to the applicable incorporation or constitution documents.
Step 5: Complete Verification
Complete the prescribed authentication and verification procedure.
Step 6: Keep the PAN Details Safe
Once the PAN is allotted, use the same correct PAN while completing GST and other business registrations.
Can Instant e-PAN Be Used for GST Registration?
Instant e-PAN is designed for eligible individual taxpayers who have not already been allotted a PAN.
The Income Tax Department states that the service is available to an individual who does not already have a PAN and has a valid Aadhaar linked to an active mobile number, along with access to DigiLocker. Minors and existing PAN holders are not eligible for the service.
This distinction is important for businesses.
A company, LLP or other non-individual entity should not assume that the individual Instant e-PAN facility is a substitute for obtaining the entity’s PAN.
For a proprietorship, the proprietor’s PAN is generally relevant to the GST application. For an incorporated or separate entity, the entity’s own PAN should be used where required.
Documents Required for GST Registration With PAN
PAN is only one part of the GST registration application.
The documents required can depend on the constitution of the business and the circumstances of the applicant.
Commonly relevant documents and information may include:
- PAN of business or proprietor
- Proof of constitution of business
- Identity and address details of proprietor, partners or authorised signatories
- Photograph of the relevant person, where applicable
- Principal place of business proof
- Bank account details, where required during the applicable process
- Authorisation or appointment documents for the authorised signatory
- Incorporation or registration documents for applicable entities
For the principal place of business, the GST Portal provides different document options depending on whether the premises are owned, rented or leased.
GST Registration Process Using PAN
Once the appropriate PAN is available, the GST registration application can be started.
Step 1: Open GST Registration
Select the option for new registration and choose the taxpayer category.
Step 2: Select State and District
Enter the State or Union Territory and district for which registration is being requested.
Step 3: Enter Legal Name
Enter the legal name exactly as it appears in the PAN database.
Step 4: Enter PAN
Provide the PAN of the business or proprietor, according to the business constitution.
Step 5: Enter Contact Details
Provide the email address and Indian mobile number of the primary authorised signatory.
Separate OTPs are used for verification.
Step 6: Receive Temporary Reference Details
After the initial verification, the registration process can continue using the information generated by the GST system.
Step 7: Complete Business Information
Enter the trade name, constitution of business, address and other applicable information.
Step 8: Add Promoter or Stakeholder Details
Provide the required information about proprietors, partners, directors or other relevant stakeholders.
Step 9: Add Authorised Signatory
Enter the required details of the person authorised to act on behalf of the business.
Step 10: Upload Documents
Upload the applicable supporting documents, including proof relating to the principal place of business.
Step 11: Complete Verification
Complete the applicable Aadhaar authentication, e-signature, EVC or DSC process according to the applicant type and GST requirements.
Step 12: Submit the Application
After submission, the GST system generates an application reference number or ARN that can be used for tracking.
PAN Validation During GST Registration
PAN validation is an important part of the GST registration process.
The GST Portal states that the constitution of business entered in the application is validated with the CBDT database against the PAN entered in Part A.
This means that the applicant should not enter business information casually.
For example, if an applicant selects a business constitution that does not correspond with the PAN records, the application may require correction or additional verification.
Before submitting the application, check:
- PAN number
- Legal name
- Constitution of business
- State
- Business address
- Proprietor or entity details
- Authorised signatory details
Common PAN Errors in GST Registration
Wrong PAN Number
Entering even one incorrect character in the PAN can cause validation problems.
Always verify the PAN before submitting the application.
Using Director’s PAN for Company
A company has its own PAN. The personal PAN of a director should not be entered as the company PAN where the entity’s PAN is required.
Using Partner’s PAN for Partnership
If the partnership firm has its own PAN, the firm’s PAN should be used for its GST registration.
Incorrect Legal Name
The legal name should correspond with the PAN database.
A trade name can be different, but it should not be entered in the legal-name field simply because it is the name customers know.
Incorrect Business Constitution
The constitution selected during GST registration should correspond with the applicant and PAN information.
Applying With an Unavailable PAN
If the required PAN has not yet been allotted, the applicant should first complete the applicable PAN process rather than entering an incorrect PAN.
PAN Card for GST Registration for Small Businesses
Small businesses should identify their business structure before starting the GST application.
A small shop operated as a proprietorship may use the proprietor’s PAN, while a registered company operating a similar business will use the company’s PAN.
Business size does not by itself determine whose PAN should be entered.
The legal constitution of the taxable person is more important for identifying the appropriate PAN.
Small businesses should also keep their PAN, business name and address information consistent across their tax and financial records.
PAN Card for GST Registration for New Companies
A newly incorporated company should use its company PAN for GST registration where GST registration is required.
The company’s directors may separately need to provide their personal identification information as promoters or authorised signatories.
The company’s PAN and a director’s PAN therefore have different roles.
Businesses should avoid mixing these details when completing the GST application.
PAN Card for GST Registration for Online Sellers
Online sellers may need GST registration depending on their business activities and applicable GST provisions.
Where GST registration is required, the appropriate PAN is part of the registration application.
An online seller operating as a proprietorship generally uses the proprietor’s PAN, while a company or LLP uses its entity PAN.
The business should also ensure that the legal name and constitution details entered during registration match the PAN records.
PAN and GST Registration After 1 April 2026
The Income Tax Department introduced the new PAN application forms from 1 April 2026 as part of the transition to the Income Tax Rules, 2026. The new forms apply to fresh PAN applications filed from that date. Existing PAN and TAN numbers remain valid.
Therefore, a business that already has a valid PAN does not need to obtain another PAN before GST registration merely because the PAN application forms were changed.
This is particularly important for existing businesses that may see references to the new PAN forms online.
The change in PAN application forms should not be confused with a requirement to replace an existing PAN.
Does PAN Need to Be Linked With Aadhaar for GST Registration?
PAN-Aadhaar requirements depend on the taxpayer category and applicable income-tax rules.
For individual PAN holders who fall under the applicable linking provisions, the Income Tax Department states that PAN-Aadhaar linking is mandatory and that failure to link can make the PAN inoperative, subject to applicable exemptions.
However, PAN-Aadhaar linking should not be treated as a universal requirement for every type of business entity.
Companies and other non-individual entities have different identification structures.
Therefore, businesses should determine the applicable PAN and Aadhaar requirements according to their constitution and taxpayer status.
What If PAN Details Are Wrong During GST Registration?
If the PAN details entered in the GST application are incorrect, the applicant should correct the information rather than trying to continue with mismatched details.
Common corrections include:
- Incorrect PAN number
- Incorrect legal name
- Wrong constitution of business
- Incorrect proprietor or entity information
- Incorrect authorised-signatory information
The correct correction process depends on the stage at which the error is discovered.
If the application has not yet been submitted, the information can generally be reviewed and corrected before final submission.
If an application has already been submitted, the applicant may need to follow the applicable GST clarification or amendment process.

- Business constitution
- Proprietor or entity details

Conclusion
PAN is a mandatory part of GST registration in India. The GST Portal requires the PAN of the business or proprietor and uses PAN-related information to validate the legal name and business constitution entered in the application.
The correct PAN depends on the structure of the business. A proprietorship generally uses the proprietor’s PAN, whereas a company, LLP or other entity with its own PAN should use the applicable entity PAN.
Businesses should also remember that PAN and GSTIN are different. PAN is used to identify the taxpayer, while GSTIN is issued after successful GST registration.
For 2026, new PAN applications are governed by the new forms introduced under the Income Tax Rules, 2026. Existing PAN numbers remain valid, so an existing business does not need a fresh PAN simply because the application forms have changed.
Before submitting a GST registration application, carefully check the PAN, legal name, business constitution, authorised signatory details and supporting documents. Accurate PAN information can help ensure that the GST registration application is matched with the correct taxpayer record.
