To reconcile mortgage payments, or any payments for that matter, from one of your bank accounts to another one of your bank accounts in TaxTank use the 'Transfer' action.

From Bank Feeds select either the bank account that sent or received the payment, find the bank transaction you want to reconcile and then select 'Transfer' from the right hand side.

Then simply select the correlating bank (ie. the one that the money came from or was paid too) and select the 'Transfer' button.

The system will then look for the related bank transaction in the other bank account and reconcile both at the same time.

If the system cant find the related bank transaction you will see a message to check the other bank account. Usually this will be due to timing, for example the bank transaction hasn't come through bank feeds yet, in which case just try again the next day.
