The GST Composition Scheme was designed to make compliance incredibly easy for small businesses. By paying a flat 1% (or 6% for service providers) on quarterly turnover, you avoid the hassle of detailed invoicing and ITC matching. But does this exemption from detailed GST compliance also excuse you from paying Income Tax in advance?

1. The Myth: "Composition Scheme Means No Advance Tax"
Many small business owners mistakenly believe that because they pay a fixed 1% tax on their turnover to the GST department every quarter (via CMP-08), they are somehow absolved from paying income tax on their profits. This is entirely false.
GST is a tax on supply, while Income Tax is a tax on profit. No matter which GST scheme you fall under, the Income Tax Act operates independently. If your estimated income tax liability for the year exceeds ₹10,000, you are legally obligated to pay Advance Tax.
2. The Intersection: Composition Scheme and Section 44AD
Almost 95% of businesses that opt for the GST Composition Scheme also opt for the Presumptive Taxation Scheme under Section 44AD of the Income Tax Act. The two schemes perfectly complement each other:
- GST Composition Scheme: Eases indirect tax compliance. (Turnover limit: ₹1.5 Cr).
- Section 44AD (Income Tax): Eases direct tax compliance by assuming profit at 6% or 8%. (Turnover limit: ₹3 Cr).
Because GST Composition dealers cannot issue tax invoices and generally deal in B2C (Business to Consumer) transactions, a significant portion of their receipts may be in cash. This means the 8% presumptive rate under 44AD often applies to them, rather than the 6% digital rate.
3. When and How to Pay Advance Tax
Your advance tax schedule depends entirely on whether you have opted for Section 44AD. Let's compare the two scenarios:
| Criteria | Composition Dealer (Opted for 44AD) | Composition Dealer (Normal Books) |
|---|---|---|
| Advance Tax Installments | Single installment. | Four installments (15%, 45%, 75%, 100%). |
| Due Date | On or before 15th March. | 15th June, 15th Sep, 15th Dec, 15th Mar. |
| Tax Calculation Base | 6% or 8% of GSTR-4 declared turnover. | Actual net profit derived from P&L statement. |
4. Reconciling CMP-08 and ITR-4 Turnover
When you file your annual ITR-4 (for Section 44AD), the Income Tax department's AI directly cross-references your gross receipts with the total turnover you declared across your four quarterly CMP-08 statements and your annual GSTR-4.
If your ITR-4 turnover is significantly lower than your GSTR-4 turnover, you will receive an automated scrutiny notice. The 1% tax you paid on your composition turnover acts as a documented trail of your actual sales volume.
Notice Prevention Tip
If the department flags a turnover mismatch and issues a notice, do not panic. Use our GST Notice Reply Generator to instantly draft a legal response explaining the reconciliation differences (e.g., exempt supplies, fixed asset sales) for your CA to review.
Conclusion
Yes, GST Composition Scheme dealers must pay advance tax if their estimated income tax liability exceeds ₹10,000. However, by combining the Composition Scheme with Section 44AD, you can defer this payment to a single installment on March 15th, making your cash flow management significantly easier.
