When exporting the invoice with a wrong coding you get "The TaxType code “OUTPUT2” cannot be used with account code ‘####’" export error.

For instance, if you used income code instead of expenses code on VAT or when you try to match EXPENSE account against REVENUE tax type.

The simplest way to fix the "The TaxType code “OUTPUT2” cannot be used with account code ‘####’" is to change the ledger account in Datamolino.

TIP: If this doesn't help, please check your Chart of Accounts in Xero and change the definition of the account. Ledger account and tax code must match.
