When you open a file, TaxCycle detects any changes in calculations that have occurred since you last opened the file. These are usually changes due to rate updates or changes to other calculations in the return.
If TaxCycle detects changes in calculations, you will see a bulletin across the top of the screen:
The Pre-flight button on the Batch Transmit page in the Client Manager allows you to check for calculation changes before transmitting a batch of returns.

This is particularly useful if you prepared and finalized returns earlier in the season and are waiting to transmit them upon EFILE system opening. It alerts you to any changes without you having to open the file and check. Any detected changes are not saved back into the file.
Under module options, you can set the dollar threshold that triggers calculation change messages:
