Why the profit of the last year is not going automatically to retained earnings? what do i doing wrong?

Hi salgado1,

Welcome to Community.  You can rest assured, this isn't that you've done wrong.  QuickBooks Online will automatically transfer the money to the retained earnings at the end of the year. This is called an 'electronic swap' and doesn't appear on any reports unless other entries have been made to the retained earnings account.

You can run a Profit and Loss report to see your retained earnings by following these steps:

1. From the left menu, select Reports

2. Choose the Profit and Loss report

3. Select All Dates from the Report Period drop-down list

4. Hit Run Report

5. Click on the Net Income to open the Profit and Loss Detail Report

You'll now be able to see the transactions that were automatically moved by QuickBooks Online to your retained earnings account.  For your reference, here's an article on how to view your retained earnings account details.

If you have any other questions, please feel free to reach back out.  We're always glad to assist!
