Generally, QuickBooks Online Payroll automatically creates default accounts where your payroll liabilities and expenses are recorded. You can customize how you track your payroll expenses in your chart of accounts by recording it in  a different register so you can meet your accounting needs. To add or edit your payroll account register, follow the steps below:

1. Go to the Gear or Settings ⚙ icon, then Chart of accounts.
2. Select New  to add a new one. Or search for the account you want to edit, then select Edit from the View register ▼ dropdown.
   Note: if you see the New category window instead of the Account window, you’re creating a subaccount. If you need to create a new parent account, switch to accountant view.
3. From the Account Type ▼ dropdown, choose Expenses or Other Current Liabilities.
4. Depending on the account type you selected, choose a Detail type.
5. Add or rename the account name in the Name field.

Then, update your payroll accounting preferences. Here's how: 

1. Go to Settings ⚙, then Payroll settings.
2. Select Edit ✎ next to Accounting.
3. Select Edit ✎ to update a specific section.
4. Choose which account the transaction of the specific payroll item should go. Then select Continue.
