- GSTN removed the block on appeals for NIL or Zero demand orders when liability is still disputed.
- Taxpayers can now file Form GST APL-01 if payment was made before the demand order was issued.
- If filing still fails, GST Helpdesk support is the defined escalation path for appeal errors.
GSTN has removed the restriction that blocked appeals against demand orders showing NIL or Zero demand, opening the filing route to taxpayers who still dispute the underlying liability. The change applies where the disputed amount had already been paid before the order was issued. It was active as of September 8, 2026.
Taxpayers can now use Form GST APL-01 to challenge such orders. The change concerns the portal’s filing validation, not a new determination of whether tax is owed. The underlying dispute remains the basis for the appeal.

The earlier system treated a demand displayed as NIL or Zero as a barrier to filing. That happened even when the taxpayer maintained that the liability itself was wrong and had paid before the demand order came out. The restriction operated at the filing stage.
The update removes that block. It allows the taxpayer to pursue the regular appellate remedy instead of being stopped because the order displays no remaining demand.
The advisory targets a narrow portal validation problem
A GSTN advisory dated 07.09.2026 underpins the change. It addresses orders that show NIL or Zero demand while a substantive disagreement over tax liability continues.
The stated trigger is specific. The taxpayer must have made payment before issuance of the demand order, according to the update. The change therefore addresses a mismatch between the amount displayed on the order and the liability the taxpayer seeks to contest.
The appeal route remains the standard GST appellate form, APL-01. The update does not describe a separate offline procedure. It restores access through the regular online route.
The support instruction accompanies the system change. Taxpayers facing a filing problem are directed to raise a ticket rather than treat the validation error as the end of the appeal process.
| Earlier portal behavior | Current portal position |
|---|---|
| Orders showing NIL or Zero demand could block an appeal | Appeals can be filed against those orders when the underlying liability remains disputed |
| The block applied even where payment came before the demand order | Payment made before issuance is the practical trigger described in the update |
| The taxpayer could be stopped at portal validation | APL-01 filing is now permitted through the regular route |
The distinction is between the figure shown as demand and the dispute behind the order. A NIL or Zero display does not, under this update, prevent the taxpayer from submitting the appeal when the stated conditions are present.
The change restores access without creating a separate filing process
The update removes a procedural obstacle. It does not announce a new tax assessment or resolve the merits of any individual liability dispute.
That leaves the appeal as the vehicle for the taxpayer’s challenge. The system change enables filing; it does not decide whether the disputed liability should be upheld or overturned.
The update also does not describe a special paper-based workaround. The normal online appellate form is the route identified for these cases. Taxpayers therefore have a way to submit the dispute even when the order itself reflects no payable demand.
The earlier restriction had created a filing barrier precisely in cases where the payment and the order’s displayed demand did not align with the taxpayer’s position. Removing the validation block addresses that access problem at the system level.
The system change was visible through September 8
The advisory was issued on September 7, 2026, and the operational change appeared in reporting dated September 8, 2026. The update is being treated as active on the GST portal on that date.
The immediate operational question is whether a taxpayer can submit the appeal against an order marked NIL or Zero. Under the updated position, the answer is yes when an underlying liability dispute exists and payment preceded issuance of the order.
A filing error now has a defined escalation path. The taxpayer can raise a ticket with the designated support channel while pursuing the online appeal route.
