If you have concerns about your Madison and/or Milwaukee property assessments, our team of experienced property tax lawyers is more than happy to assist. Because these deadlines are extremely condensed and often require gathering and reporting information about your property, it is vital you contact us well in advance of these deadlines or even before notices are issued if you believe your property has been or may be over-assessed.
