What is the Business Tax Registration (BTR) fee, and how is it being used?
The initial registration fee of $20 for new businesses was implemented on January 1, 1996. The renewal fee of $10 was implemented January 1, 1998. These fees are used to fund expenditures related to the creation and maintenance of the registration records of persons subject to Wisconsin business taxes.
Why did I receive the Business Tax Registration renewal notice?
The initial Business Tax Registration (BTR) fee of $20 covers a period of two years. At the end of the two-year period, a $10 BTR renewal fee applies for the next two-year period. The renewal fee applies to all persons holding permits or certificates subject to the BTR provisions.
My BTR Certificate expires at the end of this month. When will I receive my new certificate?
You should receive a Notice of Amount Due for Business Tax Registration and a Business Tax Registration (BTR) Certificate in the mail near the middle of the month prior to expiration. The BTR Certificate shows the new expiration date and lists all permits or certificates you hold with the department covered under the BTR provisions. The new certificate becomes effective upon receipt of the $10 renewal fee.
The business registration renewal process eliminates the process of automatically sending a new seller's permit. The BTR Certificate is now the document which shows the new expiration date of your seller's permit and any other permit or certificate you hold. You will not receive a new seller's permit in this mailing.
If you do not receive your Notice of Amount Due for Business Tax Registration and BTR Certificate before the end of the month your certificate expires, or if you have any questions, please contact the department:
Wisconsin Department of Revenue
PO Box 8902
Madison, WI 53708-8902
What happens if I do not pay the $10 Business Tax Registration renewal fee?
If you do not pay the Business Tax Registration (BTR) renewal fee by the due date, the account will become delinquent and the department may pursue reasonable collection methods.
What information is included on the Business Tax Registration (BTR) Certificate?
The Business Tax Registration (BTR) Certificate lists:
- the registrant's legal/real name, business name, primary business address, and mailing address;
- the expiration date of the certificate; and
- the various permits and certificates held by the registrant that are subject to the BTR provisions, such as:
- Wisconsin Withholding Tax Account Number
- Seller's Permit
- Use Tax Certificate
- Consumer's Use Tax Certificate
- Excise Tax Permit
Do I need to post the Business Tax Registration Certificate?
No. You should retain the BTR Certificate as proof of valid registration. If you need an updated certificate, you should contact the department and request one. You are required to post your seller's permit.
Are governmental units who hold permits subject to the Business Tax Registration fee?
State and local governmental agencies who hold permits or certificates are subject to the BTR fee. The Department of Revenue lacks the authority to impose the BTR fee on agencies of the federal government.
Are Wisconsin farmers who voluntarily withhold Wisconsin income taxes for their employees required to pay the Business Tax Registration fee?
The Business Tax Registration (BTR) fees are not applicable to agricultural employers who employ only farm labor. Those employers can notify the department by checking the appropriate line on the renewal notice and returning it to the department.
Note: If an agricultural employer also has nonfarm employees or holds a Wisconsin seller's permit, the BTR fee will apply.
Are Wisconsin household employers who voluntarily withhold Wisconsin income taxes for their domestic employees required to pay the Business Tax Registration fee?
The Business Tax Registration (BTR) fees are not applicable to household employers who employ only domestic employees, such as housekeepers, maids, butlers, cooks, nannies, or in-home caregivers. Those employers can notify the department by checking the appropriate line on the renewal notice and returning it to the department.
Note: If a household employer has employees other than household employees (domestics) or holds a Wisconsin seller's permit, the BTR fee will apply.
Are Wisconsin renewable fuel producers who use fuel they produce in their personal vehicles required to pay the Business Tax Registration fee?
A producer of 1,000 or less gallons of renewable fuel used in the producer's personal vehicle and not sold is not required to pay the Business Tax Registration fee.
Note: If a renewable fuel producer holds a motor vehicle fuel tax license or holds a Wisconsin seller's permit, the BTR fee will apply.
Are out-of-state employers who voluntarily withhold Wisconsin income taxes for the convenience of their Wisconsin resident employees required to pay the Business Tax Registration fee?
The Business Tax Registration (BTR) fees are not applicable to out-of-state employers who have no other tax connection to the State of Wisconsin. Those employers can notify the department by checking the appropriate line on the renewal notice and returning it to the department.
Note: If an out-of-state employer has a tax connection to the State of Wisconsin, such as being registered for Wisconsin sales and use tax purposes, the BTR fee will apply.
What should I do if some of the information on the Business Tax Registration renewal notice is incorrect?
We encourage registrants to keep the information on their accounts current. The Business Tax Registration (BTR) renewal notice explains what to do if changes are needed. The department will update records based on the new information and send out a corrected certificate.
What should I do if I have more than one location?
The BTR Certificate will list each location at which you hold a seller's permit. You will not receive a separate certificate for each location. However, you will receive a separate seller's permit for each location.
Although you are not required to do so, you may choose to photocopy the BTR Certificate and provide a copy to each business location.
What should I do if the Business Tax Registration Certificate is lost or destroyed?
If you are a My Tax Account user and your certificate is included in the list of letters displayed after you click on the 'View Mail' hyperlink, you can print a copy of your certificate without contacting the department. Otherwise, you should contact the department to get a replacement by calling (608) 266-2776, email
DORBusinessTax@wisconsin.gov or write to Wisconsin Department of Revenue, PO Box 8902, Madison, WI 53708-8902.
I no longer operate the business or am no longer required to hold the certificate. Why did I receive a Business Tax Registration renewal notice?
You received the Business Tax Registration (BTR) renewal notice because the department currently shows you have an active permit or certificate that is subject to BTR provisions. If you are no longer operating your business or are no longer required to hold the certificate:
- You may close your BTR account by using the 'Close Account' functionality in My Tax Account to provide a closure date and reason.
- Send the BTR Certificate and the BTR renewal notice with the appropriate line checked and the effective date entered to the Wisconsin Department of Revenue, PO Box 8902, Madison, WI 53708-8902.
