How to transmit IVP forms to the Tax Department

After assessors receive Form RP-425-IVP, Supplement to Form RP-425-E, the assessor or the Tax Department enters the data from the form into the system.

Assessors can follow the instructions below to provide the forms to the Tax Department for data entry. To protect the privacy of property owners, assessors should not retain copies of Form RP-425-IVP.

Transmit the forms weekly, unless the volume exceeds 500 forms. Transmit volumes exceeding 500 more frequently.

Transmit all forms as soon as possible after taxable status date.

  1. Verify that each IVP form is complete, legible, and accurate.
  2. Transmit only the IVP form unless the mailing address is different than the property address. If the mailing address, which is included on Form RP-425-E, is different than the property address, insert Form RP-425-E directly behind the corresponding Form RP-425-IVP. Do not include any stapled documents or other attachments, such as tax documents or worksheets.
  3. If you receive an IVP form with additional owner information attached, provide it separately. If faxing, include a separate transmittal sheet. If mailing, you can include the IVP form and the additional owner information in the same envelope, but with a separate transmittal form on top.
  4. Complete the For assessor’s use only section at the bottom of the form.
    • For Municipal code, enter the first four digits of your SWIS code.
    • For Ownership code, use only if the property is a mobile home or cooperative that is not separately assessed, enter M or C, respectively. Otherwise, leave this line blank.
  5. A complete Form RP-425.5-IVP, Enhanced STAR IVP RP-425-IVP Transmittal Form must be attached to each batch of forms you provide to the Tax Department. Ensure that all fields are completed on the transmittal form.
  6. Batch mobile homes and cooperatives separately, and provide a separate transmittal form.
  7. The current IVP form is a two-page form with a revision date of 12/19. If you receive one or more of the previous one-page IVP form, include them in a separate batch with its own transmittal form.
  8. Transmit the forms to us using secure email, mail, or hand delivery (instructions below). Regardless of the delivery method, please include a transmittal form.

Electronic transmittal

Batch the forms into a maximum of 50 per transmittal. If you have more than 50, provide a separate transmittal form for each batch, and write Batch __ of __ on the form. Each batch must include a transmittal form.

If you transmit electronically, we recommend storing the forms securely for two weeks so that we can contact you if you there are any transmission issues. After that time, or after spot-checking to ensure the records have been entered into the IVP tool, securely shred the forms. (To protect property owner privacy, assessors should not retain IVP forms long-term.)

Secure email: You will need to use a Secure Communications (SCOM) account to email the forms to us. To request an account, email Include your name, municipality, and phone number. We will send account information and instructions to you. Do not send IVP forms through regular email.
