Transitional Provisions Under GST: Overview for CMA Final

Updated 11 October 2026 · Fact-checked

Transitional provisions are rules in Chapter XX of the CGST Act (sections 139 to 142) that move taxpayers, credits and goods from the old indirect tax laws into GST. They apply from the appointed day. To answer questions, identify the situation (registration, credit or job work), then apply the matching section and its conditions.

Understand Transitional Provisions Under GST: Overview

GST replaced several central and state taxes such as excise duty, service tax and VAT. On the day GST began, businesses already held registrations, unutilised credits and goods sent out for job work under the old laws. Without special rules, they would have lost credit, paid tax twice, or had no valid registration. Transitional provisions solve this.

The appointed day is the reference date for these rules. Transitional rules look back to what existed "prior to the appointed day" and decide what happens "on or after the appointed day". Always fix the appointed day first in any problem.

Three sections matter most. Section 139 deals with migration of existing taxpayers. Section 141 deals with goods and inputs sent for job work before the appointed day. Section 142 is referred to in two places in your material: section 141 says that if job work goods are not returned in time, input tax credit is liable to be recovered in accordance with clause (a) of sub-section (8) of section 142, and rule 118 refers to the declaration for persons to whom clause (c) of sub-section (11) of section 142 applies. Read these sections together with the TRAN forms.

The rules are conditional. A provisional registration can be cancelled if the prescribed conditions are not met. Job work goods escape tax only if they come back within the time limit and the declarations are made. Miss the condition, and the benefit goes: credit may be recovered.

For your exam, treat this topic as a map. Know which section answers which problem, and know the key conditions and time limits. Many of these provisions are now historical, but questions still test the rules as they are in the Act.

Key rules to remember

Section 139(1): provisional registration: Registered under existing law + valid PAN → provisional certificate of registration from the appointed day; Subject to prescribed conditions. If the conditions are not complied with, it is liable to be cancelled unless replaced by a final certificate.
Section 139(2): final registration: Final certificate granted in the prescribed form and manner, subject to prescribed conditions; It replaces the provisional certificate.
Section 139(3): deemed not issued: Registration cancelled on the person's application that he was not liable under section 22 or 24 → certificate deemed not issued; Applies to a provisional certificate issued under sub-section (1).
Section 141: job work time limit: Return within 6 months from the appointed day; extension by Commissioner for a further period not exceeding 2 months, on sufficient cause; Section 141(1) covers inputs sent for job work, 141(2) covers semi-finished goods sent for manufacturing processes, and 141(3) covers excisable goods removed without payment of duty for tests or processes not amounting to manufacture. Each has the same six-month limit and two-month extension.
Section 141(4): declaration condition: No tax only if manufacturer and job worker declare details of goods held by the job worker on the appointed day; Form, manner and time are as prescribed.
Consequence of late return: Goods not returned in time → input tax credit liable to be recovered in accordance with clause (a) of sub-section (8) of section 142; Section 141 says this in the second proviso to each of sub-sections (1), (2) and (3), so it applies to all three job work cases. For your answer, the reference to section 142(8)(a) is enough.
Rule 118: TRAN-1 for section 142(11)(c): Every person to whom section 142(11)(c) applies → submit FORM GST TRAN-1 electronically within the period specified in rule 117 or such further period as extended by the Commissioner; The declaration furnishes the proportion of supply on which VAT or service tax was paid before the appointed day but the supply is made after, and the ITC admissible thereon. The words "a period of ninety days of the appointed day" were substituted by Notification No. 36/2017-CT dated 29.09.2017.

How to solve Transitional Provisions Under GST: Overview questions

Use this method for any question on transitional provisions.

1Fix the appointed day and the dates in the question. Note what happened before it and what happened on or after it.
2Identify the subject: registration, job work inputs, semi-finished goods, excisable goods for tests, or a TRAN-1 declaration.
3Match the subject to the section: section 139 for registration, section 141 for job work, section 142 and rule 118 for the declaration.
4List the conditions: valid PAN, prescribed conditions, return within six months, declaration by both parties, time limit for TRAN-1.
5Check each condition against the facts. Count months carefully and check whether an extension applies.
6State the consequence: tax not payable, certificate cancelled or deemed not issued, or credit recovered.
7Write a clear conclusion in one line, citing the section.

Quickest way: Subject, section, condition, consequence

When to use it: Use in MCQs and short case questions where you have under two minutes.

Underline the dates and the type of goods or registration.
Recall the section for that subject.
Test the one condition most likely to fail: PAN, six months, or declaration.
Pick the option matching the consequence.

Common mistakes in Transitional Provisions Under GST: Overview

Counting the six months from the date the goods were sent out to the job worker.
Students assume the period runs from dispatch.
Fix: Under section 141 the six months run from the appointed day, not from the date the goods were sent out.
Thinking the Commissioner can extend the period by any length.
The word extension feels open-ended.
Fix: Extension needs sufficient cause and cannot exceed a further two months.
Ignoring the declaration condition in section 141(4).
Students focus on the time limit alone.
Fix: No tax is payable only if both manufacturer and job worker declare details of goods in stock with the job worker.
Treating provisional registration as permanent.
The certificate looks like a normal registration.
Fix: It is liable to be cancelled if prescribed conditions are not complied with, unless replaced by a final certificate.
Missing the PAN requirement for migration.
Students remember only that registration under existing law is needed.
Fix: Section 139(1) needs both registration under an existing law and a valid PAN.
Quoting the ninety-day period for TRAN-1 under rule 118.
Older notes carry the original wording "a period of ninety days of the appointed day".
Fix: Rule 118 requires every person to whom section 142(11)(c) applies to file FORM GST TRAN-1. Notification No. 36/2017-CT dated 29.09.2017 substituted the ninety-day wording with the period specified in rule 117 or such further period as extended by the Commissioner.

Worked examples

Example 1

A manufacturer registered under an existing law holds a valid PAN. A friend says he need not do anything because GST registration will not apply to him. Advise under section 139.

Show the solution

He is registered under an existing law and has a valid PAN, so section 139(1) applies.
He is issued a provisional certificate of registration from the appointed day, subject to prescribed conditions.
If the conditions are not complied with, the provisional certificate is liable to be cancelled unless it is replaced by a final certificate under section 139(2).
Under section 139(3), if he applies for cancellation because he was not liable to register under section 22 or 24, the certificate is deemed not issued.

Answer: He is migrated automatically with a provisional certificate, but he must meet the prescribed conditions to get a final certificate, or it may be cancelled.

Example 2

Inputs were sent to a job worker under the existing law before the appointed day. They return after seven months from the appointed day. No extension was sought. Both parties had filed the required declaration. What is the position under section 141(1)?

Show the solution

Tax is not payable only if inputs return within six months from the appointed day.
Seven months exceeds six months.
The Commissioner could have extended the period by up to two further months (to eight months in all) on sufficient cause. That would have covered a return at seven months. But no extension was sought, so the six-month limit applies.
As the inputs did not return within the period, the no-tax benefit under section 141(1) is not available, and under the second proviso the input tax credit is liable to be recovered under section 142(8)(a).
The declaration under section 141(4) was made, but it does not cure the late return. It is a necessary condition, not a substitute for returning the goods in time.

Answer: The condition for no tax is not met because of the late return, so tax becomes payable and the input tax credit is liable to be recovered under section 142(8)(a). A Commissioner's extension of up to two months (to eight months) would have saved the position.

Exam tips

Memorise the section map: 139 migration, 141 job work, and 142(8)(a) as the place section 141 sends you for recovery of credit.
In MCQs, watch for traps on six months versus two months and on who may extend.
For case questions, write the condition, test it against the facts, then give the consequence.
Quote the section number only when sure; otherwise describe the rule in words.

Practice questions from Transition to GST (Transitional Provisions)

Transitional Provisions Under GST: Overview: frequently asked questions

What is the appointed day under the CGST Act?

It is the date from which the transitional rules look forward and back. Transitional provisions refer to events before the appointed day and those on or after it. Always mark it first when you read a question.

Why are transitional provisions needed in GST?

Businesses held registrations, credits and job work goods under the old laws when GST began. Transitional provisions prevent loss of credit, double tax and gaps in registration.

What does section 139 of the CGST Act cover?

It covers migration of existing taxpayers. A person registered under an existing law with a valid PAN gets a provisional certificate, which a final certificate later replaces.

What happens if job work goods are not returned in time?

The tax exemption under section 141 is lost. The input tax credit is liable to be recovered under clause (a) of sub-section (8) of section 142.
