U.S. Tax Information for Foreign Vendors – Submitting Your Tax Forms for Review and Approval

The appropriate Form W-8, 8233, or W-9 must be submitted to MidAmerican Energy Company's Tax Department for review and approval. The IRS requires that MidAmerican Energy maintain the ORIGINAL Form W-8 or 8233, with an original signature. However, we recommend that foreign vendors first submit the form via fax at 515-281-2289 or email at so that MidAmerican Energy's Tax Department can review the form before you submit the original. The IRS has strict guidelines on accepting the forms, and our advance review will allow us to identify errors or omissions before you submit the original form.

If you are an existing vendor, be sure to submit a retroactive statement with your Form W-8 or 8233.
