We don't have an equivalent of 990-anything. You efile using epass for an annual report to the SOS, not the Dept of Revenue. I'm not sure what is being asked.
"For example, nonprofits in Montana aren’t required to file a separate annual tax form with the state, as is the case in New York, which requires a Form CHAR500. However, there are additional filings required in Montana related to payroll taxes, property tax exemption, and your annual report."
