When you connect your Payhawk account to Sage Intacct, your input Sage Intacct taxes are automatically synced.
If you update your Sage Intacct tax rates after the connection between the two systems has been established, you have to manually update that data in Payhawk.
To manually update your tax rates in Payhawk:
In the Payhawk web portal, go to Settings > Expense fields.
Under Built-in fields, select Tax rate.
Click on Update from Sage Intacct. As a result, Payhawk will show the tax rates that apply to the specific expense.
