The company is making payments towards an invoice with CIS deductions, but the period is already filed with HMRC. How can I include does new payments?

Hi there, @luis17. 

I'm here to provide insights into the Construction Industry Scheme (CIS) in QuickBooks Online (QBO).

To include the new payments, you'll need to amend the transactions for that period. You may need to contact Our Online Support to have them unfiled. 

Here's how: 

1. Go to the Help menu, then select Contact Us. 
2. Type your concern in the description field, then click Let's Talk. 
3. Click Start a chat. 

      4. Complete the need information, then tap Submit.

Our customer support hours are Mondays to Fridays every 6:00 AM to 6:00 PM PST. Then, 6:00 AM to 3:00 PM every Saturday. For the Advanced version of QuickBooks, you can contact them any time and any day.

However, if the submission was already filed successfully with HMRC,  I suggest contacting them for the amendment process.

For future reference, please browse through this article: Record Deductions Suffered under CIS. It contains steps on how to update CIS and to see the previous records in QBO.
