0021·Sales value excluding tax, or quantity, is missing

What this means

FBR needs a taxable base. For most sale types that is the excluding-tax sales value; for specific-rate types it is quantity. A line with neither cannot be assessed.

Why it happens

• Both fields were left at zero on a Third Schedule line, where the base sits in the retail price field instead — a valid setup that can still fail if the sale type does not match.
• A value-only adjustment line was submitted with no quantity.
• The value failed to parse and defaulted to zero.

How to fix it

1. 1Confirm the sale type matches where you actually placed the taxable base.
2. 2Send both value and quantity on ordinary goods lines even where only one drives the tax.
3. 3Handle pure adjustments through notes rather than zero-value lines.
