Once you've made the last transaction to get a $0 balance and you've Reconciled the account...

Go to your Chart of Accounts and find the Acct you want to make Inactive.  At the end use the Action drop-down menu and select Make Inactive. 

If you need to see this or any other Inactive Acct.  While on the Chart of Accounts, click the Gear Icon and then check the box in front of Show Inactive.  (Uncheck it to hide them again.)
