GST sale at concessional rate of 5% to institution funded for research and development

In the scenario where you purchase goods at a higher GST rate (e.g., 18%) and sell them at a lower concessional rate (e.g., 5%), you generally do not need to reverse your Input Tax Credit (ITC) as long as the outward supply remains taxable.

Here is the breakdown of how to handle this accounting and compliance situation:

1. ITC Reversal Is Not Required

According to GST regulations, ITC reversal under Section 18(4) of the CGST Act is typically mandatory only when:

• Your output supplies become wholly exempt from GST.

• You transition from a regular taxpayer to the Composition Scheme.

Since selling at a 5% concessional rate still constitutes a taxable supply, you are entitled to continue claiming and utilizing the ITC on your purchases.

2. Handling the "Inverted Duty Structure"

When your input tax rate (18%) is higher than your output tax rate (5%), this is known as an inverted duty structure. This often leads to an accumulation of unutilized ITC in your electronic credit ledger.

• Accumulation: You can carry forward this unutilized ITC to subsequent tax periods to offset future output tax liabilities.

• Refunds: Under Section 54(3) of the CGST Act, if you have an accumulation of ITC due to an inverted duty structure, you are eligible to claim a refund of the unutilized ITC at the end of the tax period, subject to specific conditions and calculations provided by the government.

3. Accounting in Your Books

There is no special "adjustment" required for the difference in tax rates in your books; you simply record the transactions according to the applicable rates:

• Purchase Entry: Record the inventory at the purchase cost (excluding GST) and debit the GST (Input) to your "Input CGST/SGST" or "Input IGST" account at 18%.

• Sales Entry: Record the revenue and credit the GST (Output) to your "Output CGST/SGST" or "Output IGST" account at 5%.

• Ledger Reconciliation: At the end of the month, your Input Tax Ledger will likely have a higher balance than your Output Tax liability. This surplus is your "Input Tax Credit" balance, which remains in your electronic credit ledger on the GST portal.

Summary for your records:

• No Reversal Needed: You do not need to reverse any ITC because the 5% sale is still a taxable supply.

• Maintain Credit: Continue to claim the full 18% ITC on your purchases.

• Refund Option: If the ITC accumulates significantly, you are eligible to apply for a refund of the unutilized balance under the "Inverted Duty Structure" category (Section 54(3)).

• Compliance: Ensure your HSN codes and tax rates are correctly mapped in your accounting software (e.g., Tally) to reflect the 5% rate for that specific institution.

Summary: You do not need to reverse your Input Tax Credit (ITC) for selling at a lower rate (5%) as long as the supply remains taxable; instead, you may accumulate the excess credit and potentially claim a refund due to the "inverted duty structure."
