GST advance tax refund form rfd 01 interest calculation

Claiming a GST advance tax refund requires filing Form GST RFD-01 on the GST portal under the category for refund of excess balance in the electronic cash ledger or tax paid on advances. If the department fails to sanction the refund within 60 days from the date of receipt of your application, interest at 6 percent per annum becomes payable under Section 56 of the CGST Act from the 61st day until the disbursement date. Verifying your underlying input tax credit in GSTR-2B ensures your electronic cash ledger balance is not tied up in tax disputes or set-off adjustments.

Businesses frequently deposit cash advances into their electronic cash ledger or pay tax on advance receipts for services that are subsequently cancelled. When goods or services are not supplied, or when cash deposited in advance remains unutilised, the taxpayer is entitled to claim a refund through Form GST RFD-01. However, delays in departmental verification often lead to stalled payouts, making statutory interest calculations essential to protect your working capital.

Statutory framework for advance tax refunds in Form GST RFD-01

Refunds of advance payments, unutilised cash balances, and tax paid on advances are governed by Section 54 of the CGST Act read with Rule 89 of the CGST Rules. Applications must be filed electronically through the common portal in Form GST RFD-01 as outlined in Section 54 of the CGST Act. Taxpayers filing for refund of excess balance in the electronic cash ledger generate an Application Reference Number immediately upon submission.

In cases where tax was paid on an advance for a supply that was later cancelled without an invoice being issued, a refund voucher is issued under Section 31(3)(e). If tax was paid erroneously under the wrong head, such as intra-State instead of inter-State, CBIC Circular No. 162/18/2021-GST clarifies that the term subsequently held covers cases where the taxpayer discovers the error on their own ascertainment, enabling a refund claim under Section 77 in Form GST RFD-01 accompanied by Statement 6.

Common mistake: Claiming an advance tax refund without reconciling inward input tax credit in GSTR-3B against GSTR-2B. If tax officers audit the refund period and uncover ineligible ITC claims under Section 16(2)(aa), the refund amount in the electronic cash ledger may be withheld or adjusted against output tax demands under Section 73 or Section 74A.

Interest calculation on delayed refunds under Section 56

Under Section 56 of the CGST Act, if any tax ordered to be refunded is not refunded within 60 days from the date of receipt of application under Section 54(1), interest at the rate of 6 percent per annum is payable from the day immediately following the expiry of 60 days until the date of refund of such tax. In accordance with Section 170 of the CGST Act, the calculated interest amount is rounded off to the nearest rupee.

The standard interest formula applied under Section 56 is:

Interest Payable = (Sanctioned Refund Amount × 6% × Number of Delayed Days) ÷ 365

The delay period begins on the 61st day after the Application Reference Number date and terminates on the date the payment advice is issued and funds are disbursed to your bank account.

Worked example: delayed advance tax refund calculation

Consider an enterprise, Progressive Solutions LLP, that deposited an advance tax sum of ₹4,50,000 in its electronic cash ledger for a scheduled contract. The contract was terminated before work commenced, and no tax invoice was issued. The firm filed Form GST RFD-01 on 15 May 2026.

The statutory 60-day period ended on 14 July 2026. The refund order and payment advice were sanctioned on 28 August 2026, creating a delay of 45 days beyond the 60-day threshold.

Parameter Details Statutory reference
Application date (ARN generated) 15 May 2026 Section 54(1)
60-day statutory processing limit ends 14 July 2026 Section 56
Refund sanctioned and disbursed 28 August 2026 Form GST RFD-06
Number of delay days (15 July to 28 August) 45 days Section 56
Sanctioned refund amount ₹4,50,000 Electronic cash ledger
Applicable interest rate 6% per annum Section 56 notification
Interest formula applied (₹4,50,000 × 6% × 45) ÷ 365 Rule 94
Exact calculated interest ₹3,328.77 Section 56
Final interest payable (rounded) ₹3,329 Section 170 rounding

The total payout due to Progressive Solutions LLP is ₹4,53,329, comprising the ₹4,50,000 principal advance tax refund and ₹3,329 statutory interest for the 45-day delay.

How ITC reconciliation protects your advance refund claims

Before issuing a refund order, the jurisdictional GST officer verifies the applicant's compliance history across filed returns. Under Section 16(2)(aa) of the CGST Act, input tax credit can be claimed only if invoice details have been furnished by suppliers in their GSTR-1 and communicated to the recipient in Form GSTR-2B. In addition, Section 16(2)(b) stipulates that credit requires actual receipt of goods or services.

If your GSTR-3B return contains ITC claims not matched with GSTR-2B, tax authorities may initiate scrutiny under Section 73 or Section 74A. When an outstanding demand is identified, authorities can invoke Section 54(10) to withhold or adjust your electronic cash ledger refund against existing liabilities. Maintaining strict alignment between your purchase register and GSTR-2B prevents unverified credit from jeopardising legitimate cash refunds.
