    Request to Combine Tax Parcels      The request to combine tax parcels is only valid on property owned under the same ownership
    and contiguous (next to each other) property. The request typically has two reasons for being
    filled out: a property owner wishes to have one tax bill for multiple parcels or
    the owner is asking for a permit to do work that is in violation of the Zoning Code.

    The assessment will change as a result of filing this request. An important note regarding
    this request, once land is combined, Planning will not allow any land to be split unless a
    Certified Survey Map is approved and recorded.

    requested is confidential and used for the validation of commercial sales.

    New Business Personal Property form      New businesses and new owners of existing businesses in the City of Oshkosh should complete this form.
    It allows city assessors to enter your business information correctly onto the personal property roll
    and ensures any information mailed from the assessors office will go to the correct person at the correct address.

    Commercial Income & Expense form      This form is used when reviewing new properties or ones that have had a significant change
    since 2005. The three approaches to value properties are sales, cost and income. The information
