If you have rental income in three different states, then you may be required to file three different state tax returns. If a property generates a profit, then you will need to report that profit on the state return for the property's location. If that is your only income in that state, then the state's filing requirements will have to be considered in order to know whether a return is required.
If a property does not generate a profit, then a state tax return for that property would not be required because you would be reporting negative income.
All rental properties will be reported on your Federal return and Schedule E will show a breakdown for each property to see if there is a profit or a loss.
