I have two bank accounts in different currencies both reconciled through the year. However when I review my P&L it shows an income when I actually have a loss.

We appreciate you for contacting the Community, Laura.

I'd recommend checking the exchange rate you set to convert the transactions in one of your bank accounts to your home currency. It can cause discrepancies in your profit and loss statement if the exchange rate used is inaccurate. Here's how:

1. Go to the Gear icon and select Chart of Accounts.
2. Locate the specific bank account and click on the drop-down arrow to the left of the account name.
3. Click Edit, then scroll down to the Currency section and check if the correct exchange rate is selected.
4. Click Save and close.

If the exchange rate is correct, you may need to review the transactions in your foreign currency bank account to verify they are classified correctly in your profit and loss statement. 

It's also possible that there may be an issue with the reconciliation, so you may want to check to make sure all transactions are accurately matched and reconciled.
