Complete the Estate Administration Tax affidavit with less retyping

When an estate value changes after probate, an affidavit is needed for the tax adjustment — and it repeats the estate trustee's and deceased's identification details. This guide is an example of letting hivi fill the repeating fields.

Official form and source

Start from the official source and always use the current version — form numbers and links can change:

• Service page: Apply for probate of an estate — ontario.ca
• Form (Central Forms Repository): Affidavit for Estate Administration Tax – Additional Payment/Refund — 004-3039

What this form is about

The affidavit adjusts the Estate Administration Tax when the estate value is revised after the original probate filing.

Before you start: what to gather

• Your name, address, and contact information as estate trustee.
• The deceased's name and relevant estate details.
• The revised estate value and the tax adjustment calculation.

Confirm the current process on ontario.ca and seek legal advice if needed.

How hivi makes it faster

1. Store the repeating details once. Save your and the deceased's identification details in hivi.
2. Autofill the identification fields. Use the hivi Chrome extension on a web form, or fill a PDF from your saved details inside hivi.
3. Prepare the tax calculation yourself or with a lawyer.
4. Review and file yourself with the court.

Why do it in hivi

Estate paperwork repeats the same names and addresses across many documents. Stored once in hivi — in Canada, with no third-party AI — the repeating fields fill themselves.
