When completing Schedule C (Form 1040) for the 2025 tax year, the business address must be entered on Line E. You are required to provide a street address rather than a P.O. box or mail drop. If your business operates from a suite, room, or other specific location within a building, include that information (e.g., Suite 300 or Room 2B). If you conducted your business from your home and the home address is already listed on page 1 of your Form 1040, you are not required to complete Line E.
Key Instructions for Line E
- Enter the full street address of your business location.
- Include suite, room, or unit numbers if applicable.
- Do not use a P.O. box or mail drop address.
- If your business is located at your home (as shown on Form 1040, page 1), leave Line E blank.
