IRS W-9
You may be asked to complete a W-9 form if your department is receiving a payment. Please have someone in your department sign the W-9. IMPORTANT: If you expect to receive the payment directly in your department you should change the address on the W-9. The tax department will direct that any payments be made to the address on the W-9, unless you specify otherwise to the supplier. A formattable W-9 is available here.
