If you wish to change the tax rates that are on your settlements, then you can do this at any time by going to Accounts & Taxes > Account & Taxes Wizard. (Please make any changes to tax rates via the Wizard rather than the Account & Tax Mappings page.)
Any changes to your accounts and tax rates will apply automatically to any settlement on your dashboard that has not yet been sent to Xero/QuickBooks.
For settlements that have already been sent to Xero/QuickBooks, we suggest making the changes first and then rolling back each settlement. The Rollback option will remove this completely from Xero/QuickBooks and refresh the settlement;
Once refreshed you can re-send the invoice to Xero/QuickBooks so that the correct tax rates are applied.
For any rollback issues, please refer to the Why isn't the rollback option working - QuickBooks? help article.
IMPORTANT
Please ensure that the settlement already sent is deleted from Xero/QuickBooks before re-sending from Link My Books, to avoid duplication.
