Before filing your return or extension for May 15th, make sure you verify if your entity meets the thresholds to file an "EZ report" or "No Tax Due Report."
If you are filing a combined report, verify which entities actually have nexus with Texas (remember, this can change from year to year).
Also, make sure that you file the correct public information report for each entity that has nexus, and attach the correct affiliate schedule to the extension (there is one form for extension purposes and another for return purposes).
If your company has any entities that qualify as a "passive entity," remember, passive entities are not included in a combined report and are nontaxable for Texas franchise tax purposes.
Here is a link to a recent Texas powerpoint presentation to provide some helpful info.
