MN Sales Tax Exemption - Step 3

Step 3 - Provide a completed ST3, "Certificate of Exemption" to each store where you want to claim this exemption

OK, you're almost done! The last step is to file a completed ST3 form with EACH store at which you want to claim an exemption from MN Sales Taxes. It is required that you list on this form the name of the store where you will be making your purchase. Therefore, this form will be different for each store. We've filled in our store information for you in the form linked below.


ST3, "Certificate of Exemption". Below are suggested ways homeschoolers (vs. other non-profit organizations) should complete this form. These suggestions were confirmed with the Minnesota Department of Revenue, Sales and Use Tax Division. Please contact them if you have any questions about how to complete this form.

Do not check either of the first two boxes (labeled "Check if this certificate…" and "If you are a contractor…") at the top of this form. Similarly, leave blank "Exempt entity name" and "Project description". Instead, begin in the section labeled "Type or print" (gray box on the left side).

When completing this ST3 form, please fill in your information BELOW each field title. For example, the name of your homeschool (e.g. “"Johnson Homeschool") should be written BELOW the field title "Name of purchaser" and not on the line above this text. Similarly, enter your information BELOW the field titles "Business address", "City", "State", "Zip code", "Purchaser’s tax ID number", and "State of issue", and not on the line above these texts.

"Name of purchaser" - Homeschoolers should use the same name for their "organization" listed in the approval letter they received from the MN Department of Revenue. This will be the name they created for their homeschool (e.g. "Johnson Homeschool") and NOT their own personal names.

"Business address" - Homeschoolers should use the same address for their "organization" listed in the approval letter they received from the MN Department of Revenue. This will typically be their home address. Be sure to include city, state and zip code.

"Purchaser's tax ID number" - Homeschoolers should enter the MN Tax ID number listed in the approval letter they received from the Minnesota Department of Revenue. Be sure to enter "MN" in the "State of issue" field. (Note: If you are a homeschoolers who was previously approved via the ST17 form, or who received an approval letter with an "ES" tax exempt number, and did not receive a Minnesota tax ID number, you should instead list your driver's license information in the space provided.)

"Type of business" - Homeschoolers should check box #17, "Nonprofit Organization". (We've done this for you in the linked form.)

"Reason for exemption" - Homeschoolers should check box "F", "Educational organization #". (We've done this for you in the linked form.) (Note: If you are a homeschooler who was previously approved and received an "ES" tax exempt number, you should enter this number on line "F". Otherwise, this should be left blank.)

Be sure to sign and date the form at the bottom using the same title you defined in Form ST16 of Step 1, usually "Father" or "Mother".


Finally, deliver this completed ST3 Form to us either in person or by mailing it to us at:

  Heppner's Legacy Homeschool Resources
PO Box 753
Elk River, MN 55330-0753

If you currently have an on-line account on our website, or if you later create an on-line account on our website, please wait a couple of days for us to update this account before making a purchase. Otherwise MN Sales Taxes will be added to your on-line purchase.


Once we receive your completed ST3 Form, we will set things up in our systems, both in-store and in your on-line account with Heppner's Legacy Homeschool Resources, so we never charge you MN Sales Taxes again unless you ask us to do so. However, here is an important note which we received from the Minnesota Department of Revenue, Sales and Use Tax Division:

  Exemption certificates do not expire unless the information on the certificate changes. We recommend updating exemption certificates every three or four years. A purchaser may provide a blanket certificate to a vendor for all purchases. Also, applications for nonprofit exempt status from Minnesota sales and use tax for homeschools are approved based on current facts and circumstances regarding each organization and laws in effect at the time of approval. Different circumstances, statutory changes, or subsequent court decisions could affect organizations' nonprofit exempt status. Homeschools must contact us if their character or method of operation changes so we can consider the effect of the change on their status. Also, homeschools must inform us of all changes in their legal name or address.


If after you have been setup in our systems to be exempt from MN Sales Taxes, and you need to purchase something for anything other than your homeschool educational purposes, please contact us so we can be sure to charge the appropriate MN Sales Taxes for that purchase only.

As you may have heard us say, "We are here to help!" Therefore, we hope you have found this information helpful and useful.
