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 IVP 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. Do not include: Form RP-425-E, any stapled documents, or other attachments (such as tax documents or worksheets).
  3. Complete the For assessor’s use only section at the bottom of the form.
    • Enter the first four digits of your SWIS code in the Municipal code field.
    • Enter the Ownership code 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.
  4. 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.
  5. The current IVP form is a two-page form with a revision date of 08/20. If you receive one or more of the previous one-page IVP forms, include them in a separate batch with its own transmittal form.
  6. Transmit the forms to us using secure email, mail, or hand delivery (instructions below). Regardless of the delivery method, please include a transmittal form.

After that time, or after spot-checking to ensure the records have been entered into the IVP tool, securely shred the forms.
