Singapore Tax Audit File
If you have a Singapore subsidiary and nexus and you have the Tax Audit Files SuiteApp installed in your NetSuite account, you can generate a text version or an XML version of the IRAS Audit File (IAF).
You must install the International Tax Reports and Supplementary Tax Calculation SuiteApps to generate Customer Accounting transactions through the Singapore IRAS Audit File (IAF).
NetSuite generates the IAF from data entries in your General Ledger or Chart of Accounts, master data of customers and suppliers, and details of invoices, orders, payments, and adjustments.

By using the Tax Audit Files SuiteApp, you assume all responsibility for determining whether the data you generate and download is accurate or sufficient for your purposes. You also assume all responsibility for the security of any data that you download from NetSuite and subsequently store outside of the NetSuite system.
To make the generated IAF is compliant with IRAS requirements, you must do the following:
-
For transactions where the Singapore Dollar (SGD) is not the functional currency, make sure that for GST reporting purposes, the system converts the value of supply and output tax to SGD, based on the prevailing exchange rates.
-
Make sure that the Use Account Numbers preference is turned on in Setup > Accounting > Preferences > Set Up Accounting.
-
Make sure that each posting account has a unique account number in the Chart of Accounts setup. For more information, see Chart of Account Numbering.
-
Enter the company’s VAT/GST Registration No. and UEN on the company information or Singapore subsidiary record. If you do not have a OneWorld account, go to Setup > Company > Company Information. If you have a OneWorld account, go to Setup > Company > Subsidiaries and select the Singapore subsidiary.
-
Provide values for all the required data elements or fields, including:
-
UEN field on customer, partner, and vendor records. This is a custom field that shows when a Singapore subsidiary is selected on an entity record. For information, see Tracking the Unique Entity Number.
