If you collect sales tax and you've set it up in QuickBooks, you may need to enter an opening balance for your Sales tax Liability account. After your start date, your sales tax is included on your sales forms and entered into this account.
Important: Do not use this procedure if you entered historical invoices or sales receipts dated before your QuickBooks start date. Your sales tax will already be included on them and posted to the correct account. You also can skip this procedure if you entered an opening balance for each sales tax agency as you set it up.
