Welcome to the Mahaska County Treasurers webpage. 

DUE TO AN ONGOING DELAY AT THE STATE LEVEL, Counties do NOT yet have the data to process property tax statements.  The Auditor anticipates the data in August.  Therefore expect a DELAY in receiving your property tax statements.  If all goes well, we hope to mail out property tax statements the last week of August, unless we continue to get delays from the state.  We apologize for the inconvenience.
