With the Sage 50 Accounts CIS v2 module, you can correct and refund subcontractor payments, even after submitting a CIS Return. 

Edit CIS payment details

Once you've posted a CIS purchase payment, you can still go back and edit any of the following details if you need to:

• Details
• Department
• Reference
• Extra reference
• Bank reconciled flag
• Bank reconciled date

These are non-critical fields.

1. Click Transactions then select the purchase payment (PP) you want to edit.
2. Click Edit, then amend the details as required.
3. Click Save, then click Yes.

To amend other details, for example, the transaction amount, you must delete or refund the original transaction. You can then repost with the correct details. These are critical fields.
