What it means for ecommerce sellers
Two changes matter to ecommerce brands. First, the inverted duty refund formula in Rule 89(5) now deducts only the share of output tax that is paid from input credit: tax payable on the inverted rated supply × (Net ITC ÷ ITC availed on inputs and input services). This usually raises the refund for brands that buy inputs at a higher rate than they sell at, for example fabric at 5% or 12% and garments at 5%. Second, Rule 88B (deemed inserted from 1 July 2017) confirms that interest on a late GSTR-3B is charged on the part of tax paid in cash, for the days of delay.
Who it affects
- Brands with an inverted duty structure (input rate above output rate)
- Anyone who files GSTR-3B after the due date
- Taxpayers with ITC wrongly availed and utilised
Before and after
Rule 89(5): amount deducted from the refund
- Before
- Tax payable on the inverted rated supply of goods and services
- After
- Tax payable on the inverted rated supply × (Net ITC ÷ ITC availed on inputs and input services)
Interest on late GSTR-3B
- Before
- Disputed whether on gross or net tax
- After
- Rule 88B(1): on the portion of tax paid by debiting the electronic cash ledger
Interest on ITC wrongly availed
- Before
- No rule on when it is "utilised"
- After
- Rule 88B(3): from the date of utilisation (as explained in the rule) till reversal or payment
What to do
- Recompute inverted duty refund claims for applications filed on or after 5 July 2022 using the revised formula.
- Keep the Net ITC and the ITC on inputs and input services as separate figures for each refund period.
- Compute interest on a late GSTR-3B on the cash portion only, for the days of delay.

Questions sellers ask
What is the revised Rule 89(5) formula?
Maximum refund = (Turnover of inverted rated supply of goods and services × Net ITC ÷ Adjusted Total Turnover) − {tax payable on such inverted rated supply × (Net ITC ÷ ITC availed on inputs and input services)}. Notification 14/2022–Central Tax substituted the second part.
From which date does the revised Rule 89(5) formula apply?
The notification came into force on its publication, 5 July 2022. CBIC has clarified that the amended formula applies to refund applications filed on or after that date.
How is interest on a late GSTR-3B calculated under Rule 88B?
Where the supplies are declared in the return for the period and the return is filed late, interest is calculated on the portion of tax paid by debiting the electronic cash ledger, for the period of delay beyond the due date, unless proceedings under section 73 or 74 had started.
From when does Rule 88B apply?
Rule 88B is deemed to have been inserted with effect from 1 July 2017.
