Guide to Estimating Charge for Conversion of Agricultural Land
Property that has benefited from lower property taxes due to its use value assessment as agricultural land may be subject to a Conversion Charge. This occurs when its use is converted to a residential, commercial, or manufacturing, or becomes exempt and the use is no longer agricultural. The Conversion Charge is effective upon the assessor’s completion of the assessment roll in the year following the change in use. Sec.74.485, WI Statutes governs the application of the Conversion Charge.
The County Treasurer is responsible for the administration of the Conversion Charge. However, the treasurer cannot act until the actual change in use, verified by a change in class on the assessment roll, is complete. This occurs after the assessor has submitted the roll to the local Board of Review (BOR), which will resolve any outstanding issues with the assessor’s decision on the proper classification. Once the BOR is complete (typically between May and October), the assessor must provide the County Treasurer a list of the owners who converted use of agricultural acreage in the previous year. Conversion Charges are issued with a due date within 30 days of issue. Unpaid Conversion Charges will be added as special charges on the next property tax bill.
For those who want to estimate the Conversion Charge amount prior to the actual calculation by the County Treasurer, whether for estimating project costs, negotiation of purchase, or for escrow at closing, we offer the following:
| Number of acres assessed the prior January 1 as agricultural use whose use has been converted on current January 1 assessment roll. | Multiply By | $396 if 30+ acres were converted $594 if 10-30 acres were converted $793 if less than 10 acres were converted |
Equals | ESTIMATED Conversion Charge due |
Note: See the Wisconsin Department of Revenue website for ‘Questions and Answers', Agricultural Assessment Guide, and a listing of conversion charges by county.
