This account should be assigned to a tax rate without GST - for example, your GST Free Expense tax rate. This is because typically, STCs and Rebates do not have GST/VAT applied to them.If the STCs account is not set correctly, your Xero invoices may display inappropriate pricing and/or taxes.Account Limitations You may notice that for your Line items and STCs account are limited to Revenue and Assets respectively. This is to limit the error of assigning these to the wrong account within Xero.You may elect to consider your STCs either as Current Assets or as Revenue. Please consult your tax professional for more details.
