All applications must be submitted through the “Business Incentives Reporting and Building Materials Exemption Certification” area on the Illinois Department of Revenue’s (IDOR) website.
The following groups have specific instructions:
An applicant without a FEIN must go to the Illinois Department of Revenue’s (IDOR) secure website and enter his or her Social Security number. Illinois will provide an Applicant ID, which the applicant can bring to the Zone Administrator or High Impact Business project manager to complete the application.
Certificates are valid for a maximum of two years however, they can be issued for a shorter period of time. For example: if the project is a short-term project expected to last six months, the certificate may be issued for a six month time frame. It does not need to encompass an entire two-year period. The exact expiration date of each certificate will vary and is based upon the expected project completion date provided at the time the application is submitted.
No. The expiration date on the certificate is the date the certificate is no longer valid.
Yes. If your Building Materials Exemption Certificate is set to expire before your project is complete, you must seek a renewal through the Zone Administrator or High Impact Business project manager who submitted your original application.
No. Each certificate allows the contractor or entity identified on the certificate to make unlimited purchases of eligible building materials for the project identified on the certificate until the expiration date identified on the certificate. However, each time building materials are purchased, the purchaser must leave with the seller a completed EZ-1 form, identifying what was purchased, who made the purchase, for what project the purchase was made, and the purchaser’s exemption certificate number.
No. The certificate is good for the project identified to the Zone Administrator or High Impact Business project manager when the application was submitted. The original application included a contract amount. A new contract, or expansion of a contract beyond what was identified in the certificate application, would constitute a new project and require a new exemption certificate.
No. Each certificate is unique to that project. It cannot be used for any other project and can only be used for the project for which it was issued.
The applicant must provide identifying business information only for the first certificate. Each subsequent certificate can be issued based on the contractor’s FEIN or previously-issued ID, the location of the project, an estimate of the dollar amount of the materials subject to exemption, and the expected date that the project will conclude.
If you are still on the Certificate Information page, click the link in the field that is incorrect, and enter the correct information. If you are on the Verify Certificate page, click "cancel" and go back to the previous page (the Certificate Information page) to make the necessary changes. DO NOT RESCIND THE CERTIFICATE. Doing so will NOT allow you to start over. Once you rescind a certificate a new certificate CANNOT be created under that contractor’s ID for that project.
Rescinded certificates can only be reinstated by contacting the Illinois Department of Revenue.
Once a certificate is rescinded by you, it is invalid. You will not be able to issue a new certificate for that contractor for that project. You will need to contact the Illinois Department of Revenue, using the "Submit a Question" area at the bottom of this page, to reinstate a rescinded certificate.
The Illinois Department of Revenue will send a message to the email address submitted on the application with a link. The applicant can access its exemption certificate by clicking on the link in the email message and following the directions provided.
When purchasing tax exempt building materials, the purchaser must submit a signed statement to the retailer that contains the certificate number, the zone, the project, and the materials being purchased. Form EZ-1, Building Materials Exemption Certification, contains all necessary information and will be provided to certificate holders when they receive their certificates. Form EZ-1 is also available for download here.
Certificate holders are responsible for ensuring that their certificates are used only to make qualified purchases. A certificate holder who uses the certificate or allows it to be used to improperly avoid tax will be assessed taxes and penalties on the purchase, an additional monetary penalty equal to the state and local sales taxes on the purchase, and may be barred from securing additional certificates.
Building materials that are eligible for the sales tax exemption include items that are permanently affixed to real property such as lumber, mortar, glued-down carpets, paint, wallpaper, and similar affixed items.
Building Materials Exemption Certificates should be applied for and issued to the entity that will be making purchases of exempt materials, whether contractor or other entity. The certificate holder is responsible for ensuring that the certificate is used only to make qualified purchases.
No. Purchases made prior to issuance of the Building Materials Exemption Certificates cannot be exempt.
