Hello there, Deakin16. To better assist you, could you clarify what you mean by "not working"? Are you unable to see the Taxable Payments Annual Report (TPAR) options, or are you receiving a specific error message when adding a supplier? Providing these details will help us determine the issue and give you the right solution.
In the meantime, let's double-check your Account and Settings to verify if the Show TPAR options for suppliers feature is enabled.
Here's how:
Navigate to the Gear icon, and select Account and Settings.
Click the Expenses tab.
In the Suppliers section, toggle on the Show TPAR options for suppliers feature.
After enabling the feature, you can flag specific suppliers by going to All Apps > Expenses & Bills > Suppliers. Select the desired supplier, click the Edit button, and in the Taxes section, tick the box for Include this supplier in my annual TPAR.
