Consolidated GST Show Cause Notice for Multiple Financial Years: Karnataka High Court Clarifies the Law

A significant question in GST litigation is whether the tax department can issue a single consolidated Show Cause Notice (SCN) covering multiple financial years or tax periods.

The Karnataka High Court has now provided important clarity on this issue in The Commissioner of Central Tax v. M/s Chimney Hills Education Society & Ors., decided on 23 April 2026.

The Division Bench of the Karnataka High Court held that there is no statutory prohibition under Sections 73 and 74 of the CGST Act, 2017 against issuing a common or consolidated Show Cause Notice covering multiple financial years or tax periods.

The judgment reversed earlier Single Judge orders that had quashed consolidated SCNs and restored the proceedings initiated by the GST authorities.

What is a Consolidated Show Cause Notice under GST?

A Show Cause Notice (SCN) is issued by the GST department when it proposes to determine tax, interest or penalty against a taxpayer.

A consolidated SCN is a single notice that covers alleged defaults relating to more than one tax period or financial year.

For example, instead of issuing separate notices for:

• FY 2019–20
• FY 2020–21
• FY 2021–22
• FY 2022–23

the department may issue one SCN covering all these periods, provided the statutory requirements are fulfilled.

The legality of such consolidated notices had been the subject of conflicting judicial views across different High Courts.

The Karnataka High Court's 2026 judgment provides an important development in this area.

Background of the Chimney Hills GST Case

The Karnataka High Court Division Bench heard a batch of appeals filed by the Revenue against orders passed by Single Judges.

The Single Judge had quashed common/consolidated SCNs issued under Sections 73 and 74 of the CGST Act on the ground that the notices covered more than one tax period or financial year.

The Revenue challenged those orders before the Division Bench.

The principal question was whether the GST law actually restricts a Proper Officer from issuing one SCN covering multiple financial years.

After examining the statutory framework and competing judicial decisions, the Division Bench answered the issue in favour of the Revenue.

The Main Legal Question

The central question before the Karnataka High Court was:

Can GST authorities issue one consolidated SCN under Sections 73 or 74 covering multiple financial years?

The Division Bench answered:

Yes.

The Court held that Sections 73 and 74 do not contain an express prohibition against issuing a common SCN covering multiple tax periods or financial years.

According to the Court, proceedings under these provisions are concerned with tax defaults, and the statutory language does not make the issuance of a notice strictly financial-year-specific.

What Did the Karnataka High Court Hold?

The Court examined the wording of Sections 73 and 74 and the overall scheme of the GST legislation.

It concluded that there is no statutory bar on a consolidated SCN covering multiple periods.

The Court observed that interpreting the provisions as requiring a separate SCN for every financial year would effectively add a restriction that Parliament had not expressly included in the legislation.

The Division Bench therefore disagreed with the approach adopted by the Single Judge and restored the consolidated SCNs.

Why is “Any Period” Important?

A significant part of the Court's reasoning relates to the language used in Sections 73 and 74.

The provisions use expressions such as “any period” and “such periods” in relevant contexts.

The Court considered this wording to be broader than a requirement that every proceeding must necessarily be confined to one financial year.

Therefore, the mere fact that an SCN covers multiple financial years does not automatically make the notice invalid.

Does Section 73/74 Require a Separate SCN for Every Financial Year?

No.

The Karnataka High Court has clarified that the GST law does not impose such an absolute requirement.

A single consolidated SCN can cover multiple periods if the notice:

• identifies the relevant periods;
• sets out the allegations;
• specifies the proposed tax liability;
• provides sufficient particulars;
• complies with applicable limitation requirements; and
• gives the taxpayer a meaningful opportunity to respond.

Therefore, consolidation itself is not a ground to invalidate an SCN.

What About the Limitation Period?

This is one of the most important practical aspects of the judgment.

The fact that multiple financial years can be included in one SCN does not mean that the department gets unlimited time.

The statutory limitation provisions continue to apply separately to the relevant periods.

The Karnataka High Court distinguished between:

The ability to issue one consolidated notice

and

The statutory time limit for determining the tax liability.

Therefore, taxpayers should carefully examine the limitation applicable to each financial year or tax period covered by the notice.

A consolidated SCN cannot be used as a device to bypass the limitation provisions of the GST law.

Does a Consolidated SCN Automatically Become Valid?

No.

The judgment does not mean that every consolidated SCN is automatically valid.

The taxpayer can still challenge a notice on other legally sustainable grounds.

For example, issues may arise where:

• the notice is vague;
• the allegations are not clearly specified;
• the tax liability is not properly quantified;
• the relevant periods are unclear;
• the notice does not provide sufficient material;
• limitation has expired for a particular period;
• principles of natural justice are violated; or
• the Proper Officer lacks jurisdiction.

The key point is that consolidation by itself is not sufficient to invalidate the SCN.

Year-Wise Details Still Matter

Although a consolidated notice is permissible, taxpayers should carefully check whether the notice provides sufficient details for each relevant period.

For example, if an SCN covers four financial years, the taxpayer should be able to identify:

A taxpayer should not be expected to defend a vague allegation covering several years without sufficient particulars.

This is why period-wise reconciliation and analysis remain extremely important.

Consolidated SCN vs Separate SCNs

Why Did the Karnataka High Court Reverse the Earlier View?

The Single Judge had relied on earlier decisions that took the view that GST proceedings should be restricted to a particular financial year.

The Division Bench examined the statutory language and several decisions from different High Courts.

It noted that there was a divergence of judicial opinion.

The Karnataka Division Bench ultimately agreed with the approach taken by courts such as the Delhi High Court, Allahabad High Court and Jammu & Kashmir High Court, which had accepted the permissibility of consolidated notices in appropriate circumstances.

At the same time, it expressly declined to follow contrary views from certain other High Courts, including decisions from Bombay, Kerala, Madras, Andhra Pradesh and Himachal Pradesh.

Important: There Are Conflicting High Court Views

This is an important point for anyone writing or relying on this judgment.

The issue of consolidated GST SCNs has not historically been interpreted uniformly across all High Courts.

For example, certain High Courts have taken a restrictive view regarding consolidated notices for multiple financial years, while the Karnataka High Court Division Bench has now taken the view that such notices are permissible.

Therefore, the jurisdiction in which the taxpayer's case arises can be important.

The Karnataka judgment is a significant 2026 development, but taxpayers should not assume that every High Court will necessarily apply the same approach in every case.

What About the Supreme Court Position?

The legal position has also been evolving because the Supreme Court has considered related matters concerning consolidated GST SCNs.

In Vishal Maruti Jadhav v. Union of India, decided on 17 April 2026, the Supreme Court dismissed the SLP and noted the existing divergence of views on whether consolidated SCNs covering multiple financial years can be issued. The matter highlighted the importance of examining the competing High Court decisions and the statutory framework.

Accordingly, the issue remains an important area of GST litigation and should be analysed carefully based on the applicable jurisdiction and the latest binding precedent.

Practical Example

Suppose the GST department identifies alleged tax discrepancies for:

FY 2020–21: ₹5 lakh
FY 2021–22: ₹8 lakh
FY 2022–23: ₹12 lakh

Instead of issuing three separate SCNs, the department issues one consolidated notice covering all three years.

Under the Karnataka High Court's 2026 ruling, the mere fact that the SCN covers three financial years does not make it invalid.

However, the taxpayer should still check:

1. Whether each year's liability is separately identifiable;
2. Whether the allegations for each period are clear;
3. Whether the demand for each period is within limitation;
4. Whether supporting documents have been provided;
5. Whether the Proper Officer has jurisdiction; and
6. Whether adequate opportunity to respond has been provided.

What Should a Taxpayer Do After Receiving a Consolidated SCN?

Receiving a consolidated SCN covering several financial years can appear complicated.

Businesses should take a structured approach.

Step 1: Identify Every Financial Year

Create a separate working sheet for each year covered by the notice.

Step 2: Check the Limitation

Calculate the applicable statutory limitation separately for every relevant year.

Step 3: Break Down the Demand

Separate:

• Tax;
• Interest;
• Penalty; and
• Other amounts.

Step 4: Reconcile the Department's Figures

Compare the demand with:

• GSTR-1;
• GSTR-3B;
• GSTR-9;
• GSTR-9C;
• Electronic Liability Ledger;
• Books of Accounts; and
• Other relevant records.

Step 5: Identify the Legal Basis

Check whether the notice proceeds under:

• Section 73;
• Section 74; or
• another applicable provision.

Step 6: Prepare a Period-Wise Reply

Even though the SCN is consolidated, the taxpayer's response should preferably address the allegations year-wise and issue-wise.

Impact on GST Authorities

The judgment also provides practical guidance for the GST department.

A consolidated SCN can be administratively convenient where the alleged defaults across different periods are connected.

However, the department must still ensure that the notice is sufficiently detailed and legally compliant.

A consolidated format should not result in:

• vague allegations;
• absence of year-wise figures;
• unclear grounds;
• limitation violations; or
• denial of an effective opportunity of hearing.

Thus, the judgment permits consolidation but does not eliminate the department's obligation to follow due process.

Key Takeaways for Businesses

1. Consolidated SCNs are not automatically invalid

A single SCN can cover multiple financial years under the Karnataka High Court's 2026 ruling.

2. Limitation remains crucial

The department cannot use consolidation to extend the statutory limitation period.

3. Check year-wise demand

Every financial year's alleged liability should be examined separately.

4. Respond comprehensively

A consolidated SCN requires a properly structured response covering each period and allegation.

5. Jurisdiction matters

Because different High Courts have taken different approaches, taxpayers should consider the law applicable in their jurisdiction.

6. Do not ignore the notice

Even if a taxpayer believes the SCN is defective, the legal strategy should be evaluated carefully rather than simply ignoring the proceedings.

Conclusion

The Commissioner of Central Tax v. Chimney Hills Education Society & Ors. judgment is an important 2026 development in GST litigation concerning consolidated Show Cause Notices.

The Karnataka High Court Division Bench has clarified that Sections 73 and 74 of the CGST Act do not prohibit the issuance of a common SCN covering multiple tax periods or financial years.

However, this does not give the GST department unlimited powers.

The applicable limitation periods continue to apply, and taxpayers must be provided with sufficient details and an effective opportunity to defend the allegations.

For businesses, the key lesson is:

A consolidated SCN is not automatically invalid—but every financial year covered by it must be carefully examined.

Taxpayers receiving such notices should prepare a year-wise reconciliation, verify limitation, analyse the legal provisions invoked and submit a detailed response.

As GST jurisprudence continues to evolve, the issue of consolidated SCNs remains an important area for businesses and GST professionals to monitor.
