When validating a return that includes a claim for Research and Development in the prior period, but no claim in the current period, you may see the following validation errors:

Sage Corporation Tax rolls forward the details of any R and D Claim to allow figures to be allocated against in in the following period.

To clear this validation:

1. From within the latest period go to the Profit & loss account using the navigator on the left of the screen
2. Add an amount to your Administration Expenses if it is zero (ignore this step if you have a value)
3. Create an Analysis from the Administration Expenses for R and D with an amount of 1 or more
4. Allocate the above to R&D Expenditure, pick existing R and D in ‘New or existing’ and enter the amount
5. Once saved return to the Profit & loss Account
6. If you completed step 2 - remove the Allocation, Analysis and the amount you input

To ensure it has been removed:

1. Click on Claims & Reliefs. 
2. Click on R&D Expenditure.
3. Click on R&D Claims and the item should have been removed.

Make sure you re-tag your computation and click Start Again. When you click Online Filing, also click Start Again.
