Introduction
Turnover is a fundamental concept under Goods and Services Tax (GST) law in India. It determines key compliance requirements, including registration, tax liability, return filing obligations, eligibility for schemes, and audit applicability. Incorrect calculation of turnover can lead to penalties, non-compliance issues, and financial liabilities.
Understanding GST turnover is crucial for businesses to stay compliant, plan taxes efficiently, and avoid legal consequences. This article provides an in-depth breakdown of GST turnover, its components, legal provisions, implications, and practical examples to help businesses navigate this essential aspect effectively.
1. Definition of Turnover under GST
1.1 Meaning & Legal Definition
Turnover under GST is a key determinant for registration, tax compliance, and procedural requirements. The law provides multiple turnover definitions, with the most significant being “Aggregate Turnover”, as defined under Section 2(6) of the Central Goods and Services Tax (CGST) Act, 2017.
As per Section 2(6) of CGST Act, 2017:
“Aggregate Turnover” means the aggregate value of:
- Taxable Supplies (excluding inward supplies liable to Reverse Charge Mechanism – RCM)
- Exempt Supplies (supplies fully or partially exempt under Section 11 of CGST Act or Section 6 of IGST Act)
- Exports of Goods and/or Services (including Zero-rated supplies)
- Inter-state supplies of persons having the same PAN
- Exclusions: GST components (CGST, SGST, IGST, UTGST, and Compensation Cess)
1.2 Key Legal Interpretations
- Turnover is PAN-based, not state-specific – It is calculated on an all-India basis, including supplies from all registered places of business under the same PAN.
- Exempt supplies are included – Even though not liable to GST, exempt supplies must be considered in aggregate turnover.
- Reverse Charge Mechanism (RCM) exclusions – The value of supplies on which GST is payable under RCM is not included in turnover.
- GST tax amounts are excluded – The turnover computation excludes GST components and cess.
1.3 Different Types of Turnover Under GST
- Aggregate Turnover – Determines GST registration eligibility under Section 22.
- Taxable Turnover – Used for tax calculation and ITC eligibility under Section 16 & 17.
- Turnover in a State – Relevant for state-wise GST return filing & compliance under Section 2(112).
- Turnover for Composition Scheme – Determines eligibility under Section 10.
This classification ensures businesses understand turnover’s legal impact on compliance, tax liability, and GST registration obligations.
2. Significance of Turnover in GST Compliance & Taxation
2.1 GST Registration Threshold Limits (As per Section 22 of CGST Act)
| Nature of Business | Threshold Limit (₹) |
| Supply of Goods (Normal States) | ₹40 Lakhs |
| Supply of Goods (Special Category States) | ₹20 Lakhs |
| Supply of Services (All States) | ₹20 Lakhs |
2.2 Impact of Turnover on GST Returns & Compliance
- GSTR-1 Filing: Businesses with turnover above ₹5 crore must file monthly GSTR-1, while others can file quarterly under QRMP scheme.
- GSTR-9 Annual Return: Mandatory for businesses with turnover above ₹2 crore.
- GSTR-9C Audit Requirement: Required if turnover exceeds ₹5 crore, necessitating a GST Audit (Self certified)
2.3 Turnover’s Role in Composition Scheme Eligibility
- Businesses with aggregate turnover up to ₹1.5 crore can opt for Composition Scheme (Section 10 of CGST Act), paying a fixed percentage of turnover as tax.
- Service providers can opt for the scheme if turnover is up to ₹50 lakh.
2.4 Turnover Impact on E-Invoicing & E-Way Bill Compliance
- E-Invoicing – Mandatory for businesses with turnover exceeding ₹5 crore (effective 2024).
- E-Way Bill Requirement – Businesses engaged in the movement of goods must generate e-way bills if turnover exceeds ₹20 lakh (for inter-state supplies).
2.5 GST Rate Applicability Based on Turnover
- Certain small businesses benefit from lower GST rates under Composition Scheme.
- Businesses above the threshold must charge GST as per prescribed rates (5%, 12%, 18%, or 28%).
3. Formula & Key Components of GST Turnover Calculation
3.1 Formula for Aggregate Turnover
As per Section 2(6) of CGST Act, 2017:
Aggregate Turnover = (Taxable Supplies) + (Exempt Supplies) + (Export Supplies) + (Inter-state Supplies)
(Excluding: Reverse Charge Supplies + GST Amounts + Non-GST Supplies)
3.2 Breakdown of Key Components
| Component | Included in Turnover? | Legal Reference |
| Taxable Supplies | ✅ Yes | Section 2(6), CGST Act |
| Inter-State Sales | ✅ Yes | Section 2(6), IGST Act |
| Export of Goods/Services | ✅ Yes | Section 16, IGST Act |
| SEZ Supplies | ✅ Yes | Section 16, IGST Act |
| Exempt Supplies | ✅ Yes | Section 2(47), CGST Act |
| RCM Inward Supplies | ❌ No | Section 9(3), CGST Act |
| GST Collected | ❌ No | Section 15(2), CGST Act |
| Interest from FD | ❌ No | AAR Rulings |
3.3 Practical Illustration
Scenario:
M/s PQR Enterprises has the following transactions in FY 2023-24:
- Taxable Sales (Intra-State): ₹50,00,000
- Taxable Sales (Inter-State): ₹20,00,000
- Export of Goods: ₹10,00,000
- Exempt Sales: ₹5,00,000
- GST Collected: ₹9,00,000
Aggregate Turnover Calculation:
(50,00,000 + 20,00,000 + 10,00,000 + 5,00,000) = ₹85,00,000
Since the turnover exceeds ₹40 lakh, M/s PQR must register for GST under Section 22 of CGST Act.
4. Detailed Illustrations & Examples of GST Turnover
4.1 Example 1 – Computation of Aggregate Turnover for GST Registration
Scenario:
| Particulars | Amount (₹) | Included in Aggregate Turnover? |
| Taxable Supplies (within state) | 30,00,000 | ✅ Yes |
| Taxable Supplies (inter-state) | 15,00,000 | ✅ Yes |
| Export of Goods (Zero-rated) | 10,00,000 | ✅ Yes |
| Exempt Supplies (Non-GST goods) | 5,00,000 | ✅ Yes |
| Inward Supplies under Reverse Charge | 2,00,000 | ❌ No |
| Interest from Fixed Deposit | 1,50,000 | ❌ No (as per AAR rulings) |
| GST (CGST + SGST) Collected | 5,40,000 | ❌ No |
Analysis & Legal Explanation:
- The Aggregate Turnover for M/s ABC Enterprises = ₹30,00,000 + ₹15,00,000 + ₹10,00,000 + ₹5,00,000 = ₹60,00,000.
- Exclusions: Inward supplies under Reverse Charge (RCM), FD interest, and GST collected are not included in Aggregate Turnover as per Section 2(6) of CGST Act, 2017.
- Conclusion: Since the aggregate turnover exceeds ₹40 lakhs, M/s ABC Enterprises is liable for GST registration under Section 22 of CGST Act.
4.2 Example 2 – GST Applicability for Composition Scheme
Scenario:
| Particulars | Amount (₹) | Included in Turnover? |
| Intra-state taxable sales | 1,00,00,000 | ✅ Yes |
| Exempt Supplies | 25,00,000 | ✅ Yes |
| Export of Goods | 30,00,000 | ✅ Yes |
| Interest Income from Bank FD | 3,00,000 | ❌ No |
Analysis & Legal Explanation:
- Total Aggregate Turnover = ₹1,55,00,000.
- The Composition Scheme threshold for traders is ₹1.5 crore (as per Section 10(1) of CGST Act, 2017).
- Since M/s XYZ Traders’ turnover exceeds ₹1.5 crore, it cannot opt for the Composition Scheme and must comply with regular GST provisions.
5. Consequences of Exceeding GST Turnover Limit Without Registration
5.1 Legal Penalties for Non-Registration
As per Section 122 of CGST Act, 2017, the penalties for non-registration are:
Offense | Applicable Penalty |
Failure to register when liable | ₹10,000 or 10% of tax due (whichever is higher) |
Willful evasion of tax (exceeding ₹5 crore) | 100% of tax due + prosecution |
Failure to issue tax invoices | ₹10,000 per invoice |
Example:
M/s DEF Services exceeded the ₹20 lakh turnover limit for services but did not register for GST. The GST department detected the non-compliance, and the company was liable to pay GST along with interest and penalties under Section 50 and Section 122 of CGST Act.
5.2 Tax Liability with Interest & Backdated Compliance
- As per Section 73 of CGST Act, the GST Department can recover unpaid tax with interest (18% p.a. under Section 50).
- The business must file past-due GST returns, pay outstanding GST, and comply with regulations from the date it became liable for registration.
5.3 Input Tax Credit (ITC) Denial to Buyers
- Non-registered suppliers cannot issue valid GST invoices, leading to ITC ineligibility for buyers under Section 16(2) of CGST Act.
Buyers may withhold payments from unregistered suppliers, impacting business relationships.
