After you add an R68 process, you can delete it as needed. When you delete an R68 process, you can no longer view reports associated with the process.
Warning: Use caution when you delete an R68 process from which you submitted an R68 report to HMRC. After you delete an R68 process, it is possible to create a new process with the same tax claim number. If you must delete a previously run process, ensure that you do not reuse the same tax claim number with a new process.
