My client missed their payroll liabilities filing for June, caught it when filing for July. QBO says it's too late to be filed electronically. How do they file it?

Hi keepingitsimple1,

Thanks for reaching out to us here.  Welcome!  It's essential that QuickBooks Online Payroll tax payments are recorded accurately.  I'd be happy to provide the information you need to ensure a positive outcome on your books!

You can easily record the payment in your books, by following the steps here, then you can create an expense or cheque, and pay the amount outside of QuickBooks.  However, when you miss a remittance payment, there may be a penalty or interest, you'll need to pay that separately.  This shouldn't be added to the payroll tax payment.  In QuickBooks Online, you'll pay the amount as indicated in the usual fashion.  To calculate the penalty and interest, for federal tax information, go to the Interest and penalties page of the CRA website.  The penalty and interest will be paid through the CRA.  

If you have any other questions, feel free to reach back out.  We'd be glad to help!
