For all of my expenses, I pay taxes when I make the purchase. How do I get QB to show this on the expense when I am entering it in?

Hi corey-omegapower, 

You may show these purchases in QuickBooks Online by adding taxes paid on the next line item. 

First, you may need to add an account to track all the taxes paid on your purchases. I'll show you how: 

1. From the Dashboard go to the Accounting tab and select Chart of Accounts.
2. Select New in the top right corner. 
3. Click on the Account Type drop-down to select Expenses.
4. Choose Taxes Paid from the Detail Type to specify the type of account.
5. Enter the name of the account in the Name field.
   
6. You have the option of including information in the Description field Then click Save and Close.

 Now, when recording an expense make sure to add the taxes as your last item. Here's how:  

1. Select + New then choose Expense from the Vendors section.
2. You may choose a Payee or leave it blank. 
3. Select a Payment account and choose a Payment date.
4. Specify the Payment method for the expense.
5. Choose an account for your purchase then enter the amount. 
6. On the next line, add the Taxes paid account and the amount. 
   
7.  Click Save and Close.
