COM23120 - Assessing: CTSA assessments: no determination required
You should set the NDR (No Determination Required) signal in Function RAMA (Record / Amend Assessment if
- There is no income for the AP
And
- A Revenue Determination (Word 29KB), if issued, would contain only zeros
COTAX will not allow you to set the NDR signal for any AP that has a payment recorded against it.
COTAX automatically deletes the NDR signal for the AP if you later make a Revenue Determination.
For a list of functions to use in particular situations, see COM23012.
