    Name Change

    If you are only changing the business name on your account and your federal employer identification number (FEIN) did not change, provide the following information:

    • The current name on your account
    • Your tax account number
    • Your new legal or "doing business as" name
    • The date you want the change to take effect
    • A copy of the Articles of Amendment (required for legal name changes only)

    You may submit a request to change the "doing business as" name in My Tax Account. We will send you a new certificate after the change has been made.

    Address Change

    To change an address, provide the following information:

    • The current name on your account
    • Your tax account number
    • The date you want the change to take effect
    • The business and mailing address currently shown on your account
    • Your new business and/or mailing address

    You may also submit an address change request in My Tax Account.

    Change in Entity Type

    Generally a change in entity type requires you to submit a new Wisconsin Business Tax Registration. If a new federal employer identification number (FEIN) is issued to you by the Internal Revenue Service (IRS), you must submit a new Application for Business Tax Registration to the Department of Revenue (DOR).

    Note: If you are a sole proprietor changing to a single member LLC that is disregarded you do not need to submit a new application. However, you will still need to notify us of the change and include your new business name.

    Note: If you sell your business, your seller's permit is NOT transferable to the buyer. You should surrender your seller's permit to us and close your sales and use tax account.

    Reactivate your Account

    If your account is inactive and you would like to have your account reactivated so you can resume doing business under that account, please submit the following information:

    • The name of your inactive account
    • Your tax account number
    • The date you want the reactivation to take effect
    • The business and mailing address you will be using

    You may submit a request to reactivate an account in My Tax Account. We will send you a new Wisconsin Business Tax Registration Certificate after your account has been reactivated.

    Inactivate your Account

    Please submit the following information:

    • The current name on your account
    • Your tax account number
    • The address on your account
    • The date you want the inactivation to take effect (this should be the last day you are making taxable sales)

    You may submit a request to inactivate an account in My Tax Account.

    Add Additional Business Location(s)

    If you are adding an additional location(s) from which you are making taxable sales, leases, or rentals, you should complete the Wisconsin Business Tax Registration or submit the information in My Tax Account.

    Note: If you are engaged in business at more than one location, you will use the same tax account number for each additional location. However, you will receive a separate permit for each location. You must file one consolidated return that includes the information and figures for all your business locations. There is no fee to add additional business locations.

    Add a Federal Identification Number (FEIN) to Your Account

    Taxpayers can submit a request to add a federal identification number (FEIN) to their account if we do not currently have that number on record by providing us a copy of their IRS letter. The letter may be faxed to our Registration Unit at (608) 264-6884 or mailed to:

    Wisconsin Department of Revenue,
