Section 139 of the Central Goods and Services Tax Act, 2017 deals with the migration of existing taxpayers into the Goods and Services Tax (GST) regime.
GST was introduced in India with effect from 1 July 2017, replacing several indirect taxes administered under different laws. To make this transition possible, the GST law provided a mechanism through which persons already registered under the earlier indirect tax laws could move into the new GST registration framework without having to follow the same process as a completely new taxpayer.
Section 139 was therefore an important transitional provision at the time GST was introduced. It provided for the issuance of a provisional certificate of registration to eligible persons registered under existing laws and having a valid Permanent Account Number (PAN), followed by the grant of a final registration certificate subject to the prescribed requirements.
The provision also contains an important consequence for a person who was not actually liable to registration under Section 22 or Section 24 of the CGST Act and subsequently obtained cancellation on that ground: the provisional registration certificate is deemed not to have been issued.
What Is Section 139 of the CGST Act?
Section 139 is titled “Migration of existing taxpayers.”
It is contained in Chapter XX – Transitional Provisions of the CGST Act.
The basic purpose of Section 139 was to provide continuity for taxpayers who were already registered under the existing indirect tax laws immediately before GST came into operation.
Instead of requiring every existing taxpayer to start the registration process from the beginning, the law provided a migration mechanism.
The section contains three important sub-sections:
- Section 139(1) – provisional registration for eligible persons registered under existing laws and having a valid PAN.
- Section 139(2) – grant of final registration in the prescribed form and manner, subject to prescribed conditions.
- Section 139(3) – treatment of provisional registration where the person is subsequently found not to have been liable for registration under Section 22 or Section 24.
Why Was Section 139 Introduced?
Before GST, businesses could be registered under different indirect tax laws depending on the nature of their activities.
For example, a business could have been registered under:
- Central Excise;
- Service Tax;
- State Value Added Tax;
- Central Sales Tax; or
- other applicable State or Central indirect tax laws.
GST replaced a large part of this fragmented indirect tax structure with a common GST framework.
The GST Council specifically noted that existing taxpayers would be migrated to GST so that they would not have to apply for a completely fresh registration in the ordinary manner.
The objective was to make the transition smoother and reduce disruption to existing businesses.
Section 139(1) – Provisional Registration
Section 139(1) provides that, on and from the appointed day, every person who was registered under any of the existing laws and had a valid PAN would be issued a certificate of registration on a provisional basis.
The provisional registration was subject to:
- prescribed conditions;
- prescribed form; and
- prescribed manner.
The provisional certificate would continue unless it was replaced by a final certificate of registration under Section 139(2), subject to the statutory consequences where the prescribed conditions were not complied with.
What Was the “Appointed Day”?
For GST, the appointed day for the central GST framework was 1 July 2017.
Therefore, Section 139 was primarily designed as a bridge between the old indirect tax registration system and the GST registration system.
Who Was Covered by Section 139(1)?
The provision covered persons who satisfied two fundamental conditions:
- They were registered under an existing law; and
- They had a valid PAN.
The GST Council’s transitional framework explained that existing taxpayers with valid PAN were to be migrated to GST.
The migration process was therefore not intended to function as an ordinary fresh registration application for a person who had never been registered under an earlier tax law.
What Was Provisional GST Registration?
The provisional registration was essentially a temporary GST registration issued as part of the migration process.
The purpose was to allow an existing taxpayer to enter the GST system while completing the requirements necessary for finalisation of registration.
CBIC described migration as the process of issuing a provisional GSTIN to existing taxpayers registered under Central Excise and/or Service Tax before GST implementation, followed by completion and finalisation of the GST registration process.
This mechanism was particularly important during the initial implementation of GST because millions of existing taxpayers had to be brought into the new system.
Provisional Registration and GSTIN
The migration process involved the issuance of a provisional GST registration and GSTIN-related credentials.
The GST registration framework prescribed the detailed migration procedure.
Under the then-applicable Rule 24, an eligible person registered under an existing law and having a PAN was required to enrol on the common portal by validating the relevant contact details. On enrolment, provisional registration was granted and FORM GST REG-25 was used for the provisional certificate.
The migration mechanism was therefore connected with the GST registration rules rather than operating entirely independently.
Section 139(2) – Final Certificate of Registration
Section 139(2) provides that the final certificate of registration shall be granted in the prescribed form and manner and subject to such conditions as may be prescribed.
The distinction between provisional and final registration is important.
Provisional Registration
This was the initial registration issued during migration from the earlier tax system.
Final Registration
This was the GST registration granted after the prescribed requirements and verification process were completed.
Therefore, Section 139 created a transition from:
Existing registration → Provisional GST registration → Final GST registration
Why Was Final Registration Necessary?
A provisional registration was not intended to permanently replace the normal GST registration framework.
The taxpayer had to complete the prescribed migration requirements.
The registration authorities could then verify the relevant information and documents before finalising the GST registration.
The detailed procedure was prescribed through the GST Rules.
For example, the migration rules required provisional registrants to submit the prescribed application and information electronically through the common portal.
Section 139(3) – Registration Deemed Not to Have Been Issued
Section 139(3) contains an important provision.
It states that the certificate of registration issued under Section 139(1) shall be deemed to have not been issued if the registration is cancelled pursuant to an application filed by the person on the ground that the person was not liable to registration under Section 22 or Section 24.
This prevents a person who was not legally required to register from retaining the benefit of the provisional migration registration merely because the registration had initially been issued during the migration process.
Example of Section 139(3)
Suppose a person was migrated into GST from an earlier registration and received a provisional GST registration.
Later, the person determines that the business was not actually liable for GST registration under the applicable provisions of Section 22 or Section 24.
The person applies for cancellation on that specific ground.
If the registration is cancelled pursuant to that application, Section 139(3) provides that the certificate issued under Section 139(1) is deemed not to have been issued.
This is different from simply surrendering a GST registration because a business has stopped operating.
The specific statutory condition in Section 139(3) relates to cancellation on the ground that the person was not liable for registration under Section 22 or Section 24.
Section 139 and Section 22
Section 22 deals with persons liable for registration.
It establishes the general framework for determining when a person becomes liable to register under GST, subject to the provisions, thresholds and exceptions contained in the Act and notifications.
Section 139(3) specifically refers to cancellation where the person was not liable to registration under Section 22.
Therefore, Section 22 is important for understanding the consequence contained in Section 139(3).
Section 139 and Section 24
Section 24 contains categories of persons who are required to obtain compulsory registration notwithstanding the general threshold provisions, subject to the applicable statutory framework and notifications.
Section 139(3) also specifically refers to Section 24.
Therefore, when determining whether the provisional migration certificate should be treated as never having been issued under Section 139(3), the person’s liability under both Section 22 and Section 24 is relevant.
Section 139 Was Primarily a Transitional Provision
One of the most important points to understand is that Section 139 was designed for the transition into GST in 2017.
It is not the normal registration provision for businesses starting operations today.
For current registration requirements, businesses generally look to provisions such as:
- Section 22 – persons liable for registration;
- Section 23 – persons not liable for registration;
- Section 24 – compulsory registration;
- Section 25 – procedure for registration; and
- Section 26 – deemed registration.
Section 139 belongs to the transitional framework created to move existing taxpayers from the earlier indirect tax regime into GST.
Migration Was Different From Fresh Registration
A person starting a new business after GST implementation would generally apply under the normal GST registration mechanism.
An existing taxpayer registered under an earlier law at the time of GST transition was dealt with under the migration mechanism.
This distinction can be represented as:
| Situation | Relevant framework |
|---|---|
| Existing taxpayer during GST transition | Section 139 migration |
| New person becoming liable to GST | Sections 22–25 |
| Compulsory registration category | Section 24 |
| Amendment of GST registration | Section 28 |
| Cancellation of registration | Section 29 |
| Revocation of cancellation | Section 30 |
Migration Under the GST Rules
Section 139 provided the statutory framework, while the GST Rules prescribed the detailed procedure.
Rule 24 of the CGST Rules dealt with migration of persons registered under existing laws.
The procedure included enrolment on the common portal and submission of prescribed information.
The rules provided for provisional registration through FORM GST REG-25 and subsequently required the provisional registrant to furnish information and documents through the prescribed process.
This demonstrates an important principle in GST law:
The Act provides the legal authority, while the Rules provide the detailed procedure for implementing it.
Role of the GST Common Portal
The migration process was designed around the GST common portal.
Existing taxpayers were required to use their migration credentials and provide or verify relevant information.
CBIC’s migration guidance explained that existing Central Excise and Service Tax assessees with valid PANs were issued provisional credentials to access the GST portal and complete the migration requirements.
This was a major administrative change because taxpayers who had previously dealt with different tax systems were brought into a common digital GST platform.
Importance of PAN in Migration
A valid PAN was an essential condition under Section 139.
The provision specifically refers to a person registered under an existing law and having a valid Permanent Account Number.
CBIC’s migration guidance also stated that taxpayers with invalid or missing PAN details had to address the PAN issue before migration could be completed.
PAN therefore served as an important identifier in connecting the earlier tax registration system with the GST registration system.
Migration of Existing Central Excise and Service Tax Taxpayers
CBIC’s migration guidance specifically described the migration process for existing Central Excise and Service Tax assessees.
Such taxpayers were provided provisional credentials through the existing system and were required to complete the necessary enrolment process on the GST portal.
The objective was to avoid requiring an entirely fresh registration process for every existing taxpayer.
Migration of State Taxpayers
The GST migration framework also covered existing taxpayers registered under State-level indirect tax laws.
The GST Council explained that existing taxpayers registered under earlier laws were intended to migrate into GST and that existing taxpayers would not have to apply for a completely fresh registration in the ordinary manner.
This was necessary because GST replaced State VAT and several other State indirect tax systems.
Why Section 139 Was Important During GST Implementation
The introduction of GST represented a major restructuring of India’s indirect tax system.
A completely fresh registration process for every existing taxpayer could have created substantial administrative difficulty.
Section 139 therefore helped establish continuity.
The migration framework allowed:
- existing taxpayer information to be brought into GST;
- provisional GST registration to be issued;
- taxpayer details to be verified;
- final GST registration to be granted; and
- the transition to occur through the common GST system.
The GST Council specifically described migration as a mechanism through which existing taxpayers could move into GST without having to apply for fresh registration in the ordinary manner.

Migration and Transitional Input Tax Credit
Section 139 itself primarily concerns registration migration, not the substantive entitlement to transitional input tax credit.
However, Section 139 formed part of the broader transitional provisions in Chapter XX.
Other provisions of the CGST Act, particularly Sections 140 onwards, dealt with transitional credit and other matters connected with the movement from the old tax regime to GST.
The GST Council’s transitional framework separately identified provisions dealing with:
- carried-forward VAT or CENVAT credit;
- unavailed capital goods credit;
- stock-related credit;
- goods in transit;
- goods sent for job work;
- goods held by agents; and
- other transitional situations.
Therefore, Section 139 should not be confused with Section 140.
Section 139
Migration of existing taxpayers.
Section 140
Transitional arrangements for input tax credit.
Migration and Multiple Registrations
The migration framework also had to deal with taxpayers who had multiple registrations under earlier laws.
The GST migration rules contained specific provisions for cases where a taxable person had multiple registrations under the existing law on the basis of a single PAN.
For example, Rule 24 provided that a taxable person with multiple registrations under the existing law based on one PAN would receive only one provisional registration under the relevant migration provision.
This illustrates why PAN was an important component of the migration process.
Migration and Existing Taxpayer Data
The migration process also involved transferring relevant registration information from the earlier tax administration systems into the GST framework.
CBIC explained that existing Central Excise and Service Tax assessees were provided provisional credentials and were required to complete the enrolment process on the GST portal.
This allowed the GST administration to establish the taxpayer’s GST registration based on information already available under the earlier indirect tax regime, subject to the prescribed verification and migration requirements.
Special Procedures for Taxpayers Who Could Not Complete Migration
Although Section 139 established the basic migration framework, the implementation of GST involved practical difficulties for some taxpayers.
The Government subsequently issued notifications providing special procedures for taxpayers who had received provisional IDs but could not complete the migration process.
For example, Notification No. 31/2018-Central Tax dated 6 August 2018 prescribed a special procedure for completing migration for taxpayers who had received provisional IDs but could not complete the migration process.
The time period under that special procedure was subsequently extended by Notification No. 67/2018-Central Tax dated 31 December 2018.
These measures demonstrate that the statutory migration framework was supplemented by administrative procedures to address practical implementation issues.
Section 139 and Final GST Registration
The ultimate objective of the migration process was to move the existing taxpayer into the regular GST registration framework.
The provisional registration was therefore not intended to remain a separate category indefinitely.
The taxpayer was required to complete the prescribed requirements so that the GST registration could be finalised.
The detailed migration rules provided the forms and procedures for completing this process.
Section 139 and Cancellation
Section 139 also has a specific connection with cancellation of registration.
Under Section 139(3), where the registration is cancelled pursuant to an application made on the ground that the person was not liable to registration under Section 22 or Section 24, the provisional certificate is deemed not to have been issued.
This provision is important because it deals with the legal status of the migration certificate itself.
It is therefore different from an ordinary cancellation of GST registration under Section 29 after a person has been validly registered and subsequently ceases to be liable.
Section 139 vs Section 25
Section 25 provides the general procedure for registration under GST.
Section 139 was specifically designed for the migration of persons already registered under existing laws at the time GST was introduced.
| Basis | Section 139 | Section 25 |
|---|---|---|
| Main purpose | Migration of existing taxpayers | General GST registration procedure |
| Target persons | Existing taxpayers registered under earlier laws | Persons liable or otherwise eligible for GST registration |
| Nature | Transitional | Regular registration |
| Provisional registration | Central feature | Applies in specified registration situations under the Act/Rules |
| Historical role | GST implementation transition | Continuing registration framework |
Section 139 vs Section 29
Section 29 deals with cancellation or surrender of GST registration.
Section 139 deals with migration from the earlier tax regime.
The two provisions can intersect where a migrated taxpayer later seeks cancellation because it was not actually liable for registration under Section 22 or Section 24.
However, Section 139(3) contains a specific legal consequence for that particular situation.
Section 139 vs Section 140
These two sections are both part of the transitional provisions but deal with different subjects.
| Section | Subject |
|---|---|
| Section 139 | Migration of existing taxpayers |
| Section 140 | Transitional arrangements for input tax credit |
Section 139 concerns registration migration.
Section 140 concerns specified transitional ITC.
A taxpayer should therefore not treat migration of registration and transitional credit as the same legal issue.
Practical Example of Section 139
Consider a business that was registered under State VAT immediately before GST came into force.
The business had:
- a valid PAN;
- an existing tax registration; and
- a continuing business operation.
When GST was introduced, the business was brought into the GST system through the migration mechanism.
A provisional GST registration was issued under the prescribed process.
The taxpayer then completed the prescribed migration requirements so that the GST registration could be finalised.
This is the basic operation for which Section 139 was created.
Practical Example – Invalid PAN
Suppose an existing taxpayer was registered under an earlier tax law but the PAN associated with the registration was not valid.
Because Section 139(1) specifically requires a valid PAN, the taxpayer could not simply rely on the old registration information without resolving the PAN issue.
CBIC’s migration guidance specifically addressed the requirement of a valid PAN for migration.
Practical Example – Person Not Liable to Registration
Suppose a taxpayer was migrated into GST and received a provisional certificate.
Later, the taxpayer establishes that the business was not liable for registration under Section 22 or Section 24 and applies for cancellation on that ground.
If the registration is cancelled pursuant to that application, Section 139(3) provides that the certificate issued under Section 139(1) is deemed not to have been issued.
This is the specific statutory consequence provided by Section 139(3).
Importance of Section 139 for Understanding GST’s Transition
Even though the migration process was primarily relevant during the introduction of GST, Section 139 remains important for understanding the structure of the CGST Act.
It demonstrates how Parliament addressed the transition between:
Old indirect tax registration system → GST registration system
The provision also provides an example of how transitional provisions can be supported by detailed rules, forms and administrative procedures.
Key Points of Section 139
The most important points can be summarised as follows:
- Section 139 deals with migration of existing taxpayers into GST.
- It is located in Chapter XX of the CGST Act dealing with transitional provisions.
- It was designed for the transition to GST from the earlier indirect tax regime.
- Section 139(1) covers persons registered under existing laws and having a valid PAN.
- Eligible persons were issued provisional registration certificates subject to prescribed conditions.
- Section 139(2) provides for grant of the final certificate of registration in the prescribed form and manner.
- The detailed migration procedure was prescribed through the GST Rules.
- Rule 24 dealt with migration of persons registered under existing laws.
- FORM GST REG-25 was used for provisional registration under the migration framework.
- Section 139(3) deals with a person who was not liable to registration under Section 22 or Section 24.
- Where such registration is cancelled pursuant to an application on that ground, the provisional certificate is deemed not to have been issued.
- Section 139 is different from Section 25, which provides the general registration procedure.
- Section 139 is also different from Section 140, which deals with transitional input tax credit.
- PAN was a fundamental part of the migration process.
- The GST migration framework was implemented through the GST common portal.
- Special procedures were later provided for taxpayers who had received provisional IDs but could not complete migration.
- Section 139 was primarily a transitional provision associated with the implementation of GST from 1 July 2017.
Conclusion
Section 139 of the CGST Act was introduced to provide a smooth transition of existing taxpayers into the GST registration system when GST replaced the earlier indirect tax structure.
The provision allowed persons registered under existing laws and having a valid PAN to receive provisional GST registration, subject to the prescribed conditions and procedures. The provisional registration could then be followed by the grant of a final registration certificate under Section 139(2).
The detailed migration mechanism was supported by the GST Rules. Rule 24 prescribed the enrolment and provisional registration procedure, including the use of FORM GST REG-25 and subsequent submission of the required information and documents.
Section 139(3) provides a specific consequence where a migrated taxpayer’s registration is cancelled pursuant to an application stating that the person was not liable to registration under Section 22 or Section 24. In such a case, the provisional registration certificate is deemed not to have been issued.
It is also important to distinguish Section 139 from the other transitional provisions. Section 139 primarily addresses migration of registration, whereas provisions such as Section 140 deal with transitional input tax credit and other sections of Chapter XX address different aspects of the transition from the old indirect tax system to GST.
Although the original migration exercise was associated with the implementation of GST in 2017, Section 139 remains relevant for understanding how the GST framework handled the transition of existing taxpayers from the earlier tax regime into the unified GST system.
