We recommend to have Sage 50 Accounts v26 and above installed to process CIS transactions for Domestic Reverse Charge. This is because these versions automatically include tax codes which ensures your VAT Return is updated correctly. Read more >

If you don't update to v26 and above, and use Sage 50 Accounts v25 and below, you'll need to manually create the reverse charge tax codes T21 and T26 manually. 

• T21 - Your new standard rate reverse charge tax code should be linked to T1 and flagged as Reverse Charge.
  
  
  
  
• T26 Your new reduced rate reverse charge tax code should be linked to T5 and flagged as Reverse Charge.
