Limitation and interest: the working sheet for a GST demand
Six lines of arithmetic that decide whether a demand is worth fighting.
Before any legal analysis, run six computations: the limitation position for the notice and the order, the interest on tax under the Section 50(1) proviso, the interest on credit under Rule 88B(3), the graded penalty reductions, the appeal pre deposit, and the Section 128A waiver arithmetic where the year is covered. The answer to whether you should fight is usually in those six numbers.
The six computations
One. Limitation. Annual return due date for the year, the ordinary notice and order dates under the applicable provision, every extension notification relied on, and the actual dates. If the order is out of time, stop here.
Two. Interest on tax. Whether the Section 50(1) proviso applies, and the net cash liability figure rather than the gross.
Three. Interest on credit. The first month in which the credit ledger balance fell below the disputed amount, under Rule 88B(3). If it never did, the interest is nil.
Four. Penalty. The figure if paid before notice, within thirty days of notice, within thirty days of order, and on final determination.
Five. Pre deposit. Ten percent of the disputed tax for the first appeal under Section 107, and the further amount for the Tribunal under Section 112, with the statutory caps and the position for penalty only demands.
Six. Waiver. Where the year falls within Section 128A, the tax payable against the interest and penalty foregone.
Reading the numbers
Where the interest and penalty exceed the tax, and the year is covered by a waiver, the arithmetic usually says pay. That is not a concession on the law; it is a commercial decision recorded as such.
Where the tax is large and the interest is nil because the credit was never utilised, the arithmetic usually says fight, because the downside is the tax you would pay anyway.
Where limitation is arguable, fight regardless of the merits, because a limitation success is complete.
Where the pre deposit exceeds the value of the dispute, consider whether a rectification under Section 161 can reduce the demand first.
What to do on Monday
Run all six computations before the first meeting on any demand, and keep them on one page.
Update the sheet when the order is received, because the numbers change.
Keep the credit ledger extracts that support the interest computation.

Is the pre deposit refundable?
Yes, on success, with interest. Record it correctly as a pre deposit in DRC-03.
Does paying under a waiver scheme admit the liability?
Record it as a commercial closure without prejudice; that is what the covering letter is for.
Can interest be negotiated?
No. It is compensatory and arises by law. What can be corrected is the computation.
