NEW – Changes for the 2026 Lime Materials License Renewal and Tonnage Reporting Term!
- Online licensing and tonnage reporting: New this year, existing license holders can apply online for your annual Wisconsin Lime Materials license, report annual lime tonnage, and pay fees. Current license holders can follow these instructions for applying for a license on MyDATCP v3. Credentials for logging in were emailed to current license holders with their expiration notice. Coming soon will be the ability to apply for a new license online.
- License numbers changed to a six-digit number (e.g. 654321). This replaces the previous 28-012345-012345 format. The new number, and the previous number it corresponds with, can be found in the List of licensed lime distributors spreadsheet linked under the "Resources" sidebar.
- Regulatory consultants: Prior to submitting online applications for your clients, contact us at datcpfert@wisconsin.gov so that we can provide online access.
- Additional information can be found in our Frequently Asked Questions for Lime License and Tonnage Reporting document. If you have any questions or concerns, please contact us at datcpfert@wisconsin.gov or (608) 224-4537.
Any individual or business that sells or distributes lime in Wisconsin:
Needs an annual lime materials license, valid January 1-December 31. The license fee is $10/year.
Must complete an annual tonnage report and pay tonnage fees of $0.0125/ton sold in the previous year
Liming materials include agricultural lime, marl, and paper mill refuse. You must be licensed and pay the tonnage fee even if you sell by volume rather than weight.
