How to Enable Tax on iPOSpays
Merchants using iPOSpays can enable and configure taxes for transactions based on their business requirements. Taxes can be applied to regular transactions on payment terminals or to itemized transactions when using Register Lite or CloudPOS inventory. This document explains how ISOs and merchants can enable tax from the iPOSpays Portal, and how taxes can be applied and managed on payment terminals and Register Lite.
Supported Channels
The following channels support tax configuration and processing on iPOSpays:
-
POS
-
CloudPOS
— Quick Pay
— Itemized Billing
-
iPOSgo! (iOS & Android)
-
Generic Hosted Payment Page (via Merchant login on iPOSpays)
-
Register Lite
Tax Configuration Based on Merchant Use Case
Based on the merchant’s use case, taxes can be configured in different ways:
-
If the merchant uses POS, CloudPOS, or iPOSgo!, taxes can be configured from both the ISO login and the Merchant login in the Edit Parameter module of the iPOSpays Portal.
-
If the merchant uses Register Lite or CloudPOS Itemized Billing, taxes must be configured in the Inventory module under the Merchant Login.
Configuring the Tax for Merchants Processing Regular Transactions
Taxes can be configured on the payment terminal to apply tax percentages automatically during transactions. Both ISOs and Merchants can configure tax settings from the Tip & Taxes tab in the terminal parameters. However, some options are controlled only by the ISO, while merchants can configure the remaining parameters.

Click S.T.E.A.M from the left menu.
