C-Series returns are prepared by tax agents who use their own computer software packages to produce paper-based return details. These printed details are then fastened inside an ordinary tax return and sent to us.
The format of the tax agents' printed-out details must match the keypoints in the tax return form and must be certified by us before you can use it.
Each year we supply the C-Series returns specifications to interested software developers and tax agents. These specifications set out our layout and data entry requirements so we can process the returns promptly and efficiently.
The C-Series returns specifications are available to anyone who applies for them. You can get them by writing to:
