Sandbox scenario · SN018
Services where federal excise duty is charged in sales tax mode
The services counterpart of SN017. Assigned wherever the profile is in the Services sector, and to every Service Provider activity regardless of sector — so service businesses clear this alongside SN019 as a pair.
What to send
These strings are matched by FBR's API. Send them exactly as published — including any irregular spacing or punctuation, which is deliberate and not a typo.
- scenarioId
- SN018
- saleType
- Services (FED in ST Mode)
- FBR description
- Services rendered or provided where FED is charged in ST mode
scenarioId is sandbox-only. It is required on sandbox submissions and must be omitted from production invoices — FBR derives the treatment from the sale type once you are live.
Who has to pass SN018
FBR assigns scenarios from your sales tax profile — your business activity and your sector. 20 of the 104 possible profiles are assigned this one.
- Manufacturer Services
- Importer Services
- Distributor Services

- Service Provider every sector

What gets SN018 rejected
- 01
Nearly always assigned together with SN019. Clearing one and not the other leaves the production token locked.

Description of this scenario was revised by PRAL on 24 July 2025.
- 03
Services carry their own HS-code equivalents; a goods HS code returns error 0052.
