The Auditor’s Office has created a levy calculator for the upcoming November election which is located on the profile page of each individial parcel. Begin by running a property search using a parcel number, address, or owner name. Once the parcel has been selected, look for "Levy" at the top left side of the web page and select that link to view the impact of the levies up for a vote.


Butler County Auditor Roger Reynolds addresses the media on Feb. 24, 2020 to advocate for House Bill 499 and fuel quality testing. The bipartisan bill, introduced by Reps. George Lang and Brigid Kelly, would allow county auditors the authority to test fuel for octane level, water and sediment. Also pictured are Ross Twp. Trustee Tom Willsey, Reily Twp. Trustee Nick Schwab, Lang and Kelly. Although the bill never received a vote, two more fuel quality bills have been introduced during the current 134th General Assembly - HB 144 and SB 71.
