Dos and Don'ts

When filling out the Illinois Reg 1 form, it is important to follow certain guidelines to ensure accuracy and completeness. Here are some things you should and shouldn't do:

  • Do use your mouse or Tab key to navigate through the fields.
  • Don't use a PO Box for your primary business address; provide a street address instead.
  • Do provide the correct Social Security number if you are a proprietorship.
  • Don't leave any required fields blank; ensure all necessary information is filled out.
  • Do check the organization type that applies to your business.
  • Don't forget to attach any necessary schedules, like Schedule REG-1-L, if applicable.

Following these tips can help streamline the registration process and avoid potential delays. If you have questions, don't hesitate to reach out to the Illinois Department of Revenue for assistance.

Misconceptions

  • Misconception 1: The REG-1 form is only for large businesses.

    • This is not true. The REG-1 form is designed for all types of businesses, regardless of size. Whether you are a sole proprietor or a corporation, this form is essential for registering your business in Illinois.

  • Misconception 2: You need to complete the form in person.

    • Many people believe that the REG-1 form must be filled out in person. However, you can conveniently complete this form online using MyTax Illinois. This platform streamlines the registration process and saves time.

  • Misconception 3: Only new businesses need to file the REG-1 form.

    • Existing businesses that change their structure, ownership, or address must also file the REG-1 form. It is important to keep your business registration up to date to avoid potential legal issues.

  • Misconception 4: You can use a PO Box for your business address.

    • This is incorrect. The REG-1 form requires a physical street address for your business. Using a PO Box is not acceptable, as it does not provide a verifiable location for your operations.

    • Filing the REG-1 form does not guarantee instant approval. The Illinois Department of Revenue reviews all applications, and processing times can vary. Ensure that all information is accurate to avoid delays.
