Withholding Tax Deduction

This s a documentation page for our shiny new REST API - you weren't meant to find it. This API isn't ready for public use yet. We're chopping and changing it a LOT as we grow it. So if you build something that uses it then it's very likely to break in a future update. Don't say you weren't warned!





Response Formats:



Allows to apply withholding tax deduction on a particular entity (invoices/purchases), if CIS deduction is enabled for the customer/supplier invoiced.

POST Operation

Applies withholding tax deduction. If CIS is successfully applied, this API responds with the updated entity (invoice/purchase) resource having an additional line item for CIS deduction. The amount of deduction applied depends on the WithholdingTax Settings for the user.

This API method does not require a request body.

URL : internal/{objecttype}/{objectnumber}/withholdingtaxdeduction

Valid inputs for {objecttype} are ‘invoices’ and ‘purchases’
