Section 45 CGST Act — Final Return & GSTR-10 After GST Cancellation

1. Why Section 45 matters

Searches such as “Section 45 CGST Act”, “Section 45 GST”, “GST final return”, “GSTR-10”, “GSTR-10 due date”, “final return after GST cancellation” and “what happens after GST registration cancellation” all point to the same compliance question: what must a taxpayer do after GST registration is cancelled?

Section 45 answers that question by requiring the applicable registered person whose registration has been cancelled to furnish a final return. Rule 81 prescribes FORM GSTR-10 for that final return. The final-return exercise is closely connected with Section 29 cancellation, especially the liability relating to stock and capital goods at the time of cancellation.

2. What Section 45 means

Section 45 applies after cancellation of registration to a registered person who is required to furnish a return under Section 39(1). The provision requires a final return within the prescribed period and in the prescribed form and manner.

3. Statutory framework

The current Section 45 framework provides that every registered person required to furnish a return under Section 39(1), whose registration has been cancelled, must furnish a final return within three months of the date of cancellation or the date of the cancellation order, whichever is later, in the prescribed form and manner.

Rule 81 prescribes FORM GSTR-10 as the final return. The Rule states that it is furnished electronically through the common portal, either directly or through a notified Facilitation Centre. citeturn0search16turn0search20

4. Who has to file GSTR-10?

The statutory trigger is not simply “anyone whose GSTIN is cancelled.” Section 45 refers to a registered person who is required to furnish the return under Section 39(1) and whose registration has been cancelled.

Special categories that do not fall within the Section 39(1) return population should be checked separately under the relevant provisions.

5. GSTR-10 due date

The statutory time limit is three months from the date of cancellation or the date of the cancellation order, whichever is later.

The original GST framework and GST Council records also describe the three-month rule. citeturn0search0turn0search2

6. Effective date vs cancellation order date

This distinction is important in practical GSTR-10 computation. A cancellation order can specify an effective date of cancellation that is different from the date on which the order is passed.

Section 45 deliberately uses whichever of the two dates is later. Therefore, the compliance team should not automatically calculate three months from the date displayed on the portal without reading the cancellation order.

7. What is GSTR-10?

FORM GSTR-10 is the prescribed Final Return under Rule 81. The historical prescribed form captures, among other details, GSTIN, legal/trade name, correspondence address, effective cancellation date, cancellation-order reference and the stock/capital-goods information relevant to the final tax calculation.

The prescribed form specifically includes details of:

• inputs held in stock where invoice is available;
• inputs contained in semi-finished or finished goods;
• capital goods/plant and machinery;
• invoice or bill-of-entry details;
• quantity and value; and
• CGST, SGST/UTGST, IGST and cess amounts.

These fields are reflected in the prescribed GSTR-10 form under Rule 81. citeturn0search17

8. Section 29(5) stock liability

Section 29(5) is the key provision to read with Section 45. When registration is cancelled, the registered person is required to pay an amount relating to ITC contained in stock of inputs, semi-finished goods, finished goods and capital goods, or the output tax payable on such goods, as prescribed, generally comparing the two amounts.

The relevant stock is considered as prescribed with reference to the cancellation date. The amount is worked through the applicable Section 29(5), Rule 20 and final-return framework.

9. Capital goods and plant & machinery

Capital goods require special attention because the cancellation calculation is not simply the same as ordinary closing stock. The taxpayer should identify capital goods/plant and machinery on which ITC was availed and apply the statutory calculation prescribed for cancellation.

The final-return working should preserve:

• asset description;
• invoice date and number;
• original ITC;
• remaining useful-life calculation where relevant;
• applicable tax amount; and
• amount ultimately discharged.

10. Electronic credit/cash ledger

The cancellation-related amount may involve debit of the electronic credit ledger and/or cash ledger in accordance with the applicable provisions. GST guidance has clarified that the stock-related debit need not necessarily be completed as a pre-condition to submitting the cancellation application and can be addressed at the final-return stage.

The GST FAQ specifically explains that the Section 29(5) amount can be discharged through the electronic credit/cash ledger and that it can be dealt with at the time of GSTR-10. citeturn0search19turn0search21

11. Cancellation and final return

Cancellation under Section 29 and final return under Section 45 are separate legal steps.

12. Pending returns before GSTR-10

A taxpayer should not treat GSTR-10 as a substitute for pending periodic returns. The cancellation process and final-return process operate alongside the taxpayer's outstanding statutory obligations.

In practical cancellation compliance, first prepare a complete return-status statement covering all tax periods up to the applicable cancellation period, then calculate the final-return position.

13. Late filing consequences

Failure to furnish GSTR-10 within the prescribed time can result in late-fee consequences under Section 47 and may lead to departmental follow-up for the unfiled final return.

GST Council material records the historical late-fee structure for GSTR-10 as ₹100 per day under CGST and a corresponding amount under the State/UT law, subject to the statutory maximums applicable at the relevant time. citeturn0search4

Because late-fee provisions can be amended or waived for specific periods, the applicable amount should be checked against the law and notification in force for the relevant default.

14. Best-judgment assessment when GSTR-10 is not filed

Failure to file the final return can trigger departmental notice and assessment procedures. GST guidance has historically provided for a notice to the return defaulter and, if the return is still not furnished within the prescribed response period, best-judgment assessment under Section 62 read with the applicable Rules.

GST Council material records the historical workflow: GSTR-3A notice, followed by best-judgment assessment in FORM GST ASMT-13 where the taxpayer continues to default. citeturn0search19turn0search23

15. Late-fee relief history

The Government has periodically introduced amnesty/late-fee relief for delayed GSTR-10 filing. These are period-specific concessions, not permanent changes to the Section 45 deadline.

For example, the GST Council's 49th meeting considered an amnesty for persons who had failed to file GSTR-10 and furnished it between 1 May 2023 and 31 July 2023, with late fee above ₹1,000 proposed to be waived. citeturn0search5

This history demonstrates why late-fee calculations should always be checked against the notification applicable to the actual default period.

16. Documents required

• GST cancellation application/order;
• effective cancellation date;
• cancellation order date;
• last filed GSTR-1/GSTR-3B;
• stock register as on cancellation date;
• purchase invoices and bills of entry;
• capital-asset register;
• ITC ledger;
• electronic credit and cash ledger;
• credit/debit note register;
• closing inventory valuation;
• Section 29(5) calculation; and
• GSTR-10 filing acknowledgement.

17. Final GST reconciliation

Before filing GSTR-10, perform an exit reconciliation:

18. ITC at cancellation

The cancellation process requires careful separation between:

• ITC already availed and used;
• ITC lying in the electronic credit ledger;
• ITC embedded in closing stock;
• ITC embedded in semi-finished/finished goods; and
• ITC relating to capital goods.

The final liability should be determined using the applicable Section 29(5) and Rules rather than simply reversing the entire electronic credit ledger balance.

19. Credit/debit notes

Credit notes and debit notes issued around the cancellation date can materially affect the final GST position. The taxpayer should reconcile notes that were reported before cancellation and notes issued or received after cancellation where they relate to supplies made before cancellation.

Cancellation does not retrospectively erase the underlying supply or the tax obligations connected with it. Each adjustment must be analysed under the applicable Section 34 and return rules.

20. Multiple GSTINs

Where an entity has GST registrations in multiple States/UTs, Section 45 applies registration-wise. Cancellation of one GSTIN does not automatically mean that all other GST registrations are cancelled.

Maintain a separate final-return tracker for each GSTIN showing:

• GSTIN;
• effective cancellation date;
• order date;
• GSTR-10 due date;
• Section 29(5) calculation;
• pending returns;
• late fee, if any; and
• filing acknowledgement.

21. Construction and infrastructure examples

For construction, mining, roads, irrigation and infrastructure businesses, GST cancellation may occur after a project closes or a registration is no longer required. Final-return preparation should therefore be integrated with project closure.

22. Detailed practical examples

Example 1 — voluntary cancellation

A company stops taxable operations and obtains GST cancellation. It identifies the later of the effective cancellation date and order date, then calculates the Section 45 three-month deadline.

Example 2 — stock on hand

The company has inputs remaining on the cancellation date. The final working identifies the relevant ITC/output-tax amount under Section 29(5) and reports it through the final-return process.

Example 3 — capital machinery

A machine on which ITC was availed remains in the business when registration is cancelled. The taxpayer performs the prescribed capital-goods calculation rather than simply ignoring the asset.

Example 4 — retrospective cancellation

The cancellation order specifies an effective date earlier than the order date. The taxpayer calculates the Section 45 deadline from the later of the two dates.

Example 5 — pending GSTR-3B

Registration is cancelled while earlier GSTR-3B returns remain pending. The taxpayer completes the outstanding return compliance and separately prepares GSTR-10.

Example 6 — credit note after cancellation

A supplier issues a credit note relating to a pre-cancellation purchase. The taxpayer examines the applicable current provisions and ensures the tax/ITC adjustment is properly documented.

Example 7 — multi-State company

One GSTIN is cancelled while registrations in three other States remain active. Only the cancelled registration enters its Section 45 final-return process.

Example 8 — no closing stock

A service business has no goods or capital goods requiring Section 29(5) payment, but it still needs to assess the final-return requirement and outstanding liabilities.

Example 9 — GSTR-10 late

A taxpayer misses the three-month deadline. The company checks the applicable Section 47 late fee and any current amnesty/relief notification before filing.

Example 10 — construction project closure

A project GST registration is cancelled after completion. The finance team reconciles RA bills, materials at site, capital assets, subcontractor ITC, credit notes, outstanding liabilities and GSTR-10 before closing the GST file.

23. Legislative timeline

24. GST Council background

The original GST return framework contemplated a final return after cancellation from the beginning. GST Council records show that Section 45 was part of the original CGST/SGST return architecture.

Later Council discussions focused on practical implementation, availability of GSTR-10 on the portal, cancellation-related compliance and late-fee relief. The 31st GST Council agenda specifically recorded the three-month Section 45 requirement and the initial portal-availability problem. citeturn0search0

The 43rd GST Council meeting also considered requests for relief from GSTR-10 late fees, demonstrating that final-return compliance remains relevant even after the registration itself has ceased.

29. Section 45 GST FAQs

What is Section 45 of the CGST Act?

Section 45 governs the final return that an applicable registered person must furnish after GST registration is cancelled.

What is GSTR-10?

GSTR-10 is the prescribed final return under Rule 81 for a registered person required to furnish a final return under Section 45.

What is the GSTR-10 due date?

The statutory deadline is three months from the date of cancellation or the date of the cancellation order, whichever is later.

Is GSTR-10 required after GST cancellation?

For a registered person falling within the Section 45 population, yes. The exact applicability should be checked against the person's return category and cancellation facts.

Does GST cancellation remove previous tax liabilities?

No. Cancellation does not extinguish liabilities or obligations relating to periods before cancellation.

What is Section 29(5) in relation to GSTR-10?

Section 29(5) deals with the tax/ITC amount connected with stock, semi-finished/finished goods and capital goods at cancellation. GSTR-10 is the final-return mechanism through which the closing position is reported.

Do I have to reverse the entire ITC balance on cancellation?

No. The cancellation liability must be determined using Section 29(5) and the applicable Rules. It is not automatically equal to the entire electronic credit ledger balance.

Can GSTR-10 be filed before the cancellation order?

The final-return obligation is triggered by cancellation and the statutory deadline is measured from the later of the cancellation date or cancellation-order date. The practical filing sequence should follow the cancellation order and portal procedure.

What happens if GSTR-10 is not filed?

Late-fee and departmental return-default consequences can arise. The taxpayer may receive a notice and, if the default continues, assessment proceedings may follow under the applicable provisions.

Is GSTR-10 required for a composition taxpayer?

Do not apply the regular Section 45 workflow blindly. Composition taxpayers have a different return framework, so the specific cancellation and final-return requirements should be checked for the relevant period.

Is GSTR-10 the same as GSTR-9?

No. GSTR-9 is the annual return under Section 44; GSTR-10 is the final return after cancellation under Section 45.

Does GSTR-10 cover stock?

Yes. The prescribed GSTR-10 form includes details relevant to inputs in stock, inputs contained in semi-finished/finished goods and capital goods/plant and machinery for the cancellation-related tax calculation.

Does cancellation affect electronic credit ledger balance?

The taxpayer must address the cancellation-related liabilities under Section 29(5) and the applicable Rules. The remaining ledger position should be reconciled as part of the exit process.

Can a cancelled GSTIN still have tax liability?

Yes. Cancellation does not extinguish liabilities for periods before cancellation or other obligations under the GST law.
