Missed the 90-Day Estate Information Return Deadline in Ontario?

💡

Once the Superior Court of Justice issues your probate certificate in Ontario, you have exactly 90 days to submit the Estate Information Return (EIR) to the Ministry of Finance. Failing to file can result in fines up to $1,000 or more, but filing a late or amended return immediately is the best way to fix the mistake.

Navigating probate in Ontario involves strict government deadlines that can easily overwhelm a grieving family 📅. Most executors know they have to pay the Estate Administration Tax (EAT) when they apply for probate at the courthouse. However, many are completely unaware that there is a mandatory “Part Two” to this process. After the court grants you the legal authority to act, the Ontario Ministry of Finance requires you to file a detailed breakdown of the estate’s assets.

This document is called the Estate Information Return (EIR). Whether you are administering an estate in London, Hamilton, or Toronto, you have exactly 90 calendar days from the date your Certificate of Appointment is issued to file this return online or by mail. If you missed this deadline, panic is a normal reaction, but ignoring the problem will only make it worse. Under the Estate Administration Tax Act, dodging this requirement can lead to severe audits and financial penalties. We will explain how to correct a missed deadline and get the estate back into compliance .

Step-by-Step Process for Handling a Late EIR in Ontario

The Ministry of Finance wants compliance, not necessarily to punish innocent mistakes. Taking proactive steps to file as soon as you realize the error is your best defence.

Step 1: Identify Your Exact Deadline

Look at the physical Certificate of Appointment of Estate Trustee you received from the Superior Court of Justice 🔍. The 90-day countdown begins on the exact date printed on that seal, not the day you received it in the mail. Count the calendar days. If you are past day 90, you are technically in default, and you need to act immediately.

Step 2: Finalize All Asset Valuations

The EIR requires you to list the Fair Market Value of all assets (real estate, bank accounts, vehicles, investments) exactly as they were on the date of death. You cannot guess these numbers. Ensure you have official bank statements, real estate appraisals, and investment portfolio snapshots. The Ministry cross-references these details to ensure you paid the correct amount of probate tax upfront .

Step 3: Submit the EIR Immediately

Do not wait for the Ministry to send you a warning letter. Go to the Ontario Ministry of Finance’s online Tax Services portal or download the official PDF. Fill in all the required asset descriptions and values. Submitting the form late is infinitely better than not submitting it at all. Often, if you submit it a few weeks late without prompting, the Ministry processes it without initiating penalty proceedings.

Step 4: File an Amended Return if Needed

Sometimes executors miss the deadline because they are waiting to discover if the deceased had a secret bank account. Do not delay the initial filing for this! You should file the EIR with the information you have within the 90 days. If you later discover new assets, Ontario law gives you 30 days from the date of discovery to file an Amended Estate Information Return and pay any additional tax owed .

How Much Does it Cost in Ontario?

Filing the return itself is an administrative task, but the penalties for evasion are steep 💵.

Action / Penalty TypeEstimated Cost (CAD)
Filing the EIR$0 (The Ministry does not charge a fee to submit the form).
Failing to File PenaltyFines can range from $1,000 up to twice the amount of the tax payable.
Corporate Appraisals$500 – $2,000+ (Required to prove the exact value of the assets).
Lawyer or Accountant FeesOften $300 – $600 to have a professional properly draft and file the EIR for you.

Because the EIR is a legally binding tax declaration, most executors choose to have their estate lawyer handle the submission. A legal professional ensures that assets like joint accounts or insurance payouts with named beneficiaries are correctly excluded, protecting you from overpaying.

How Long Does the Process Take?

Filing the return online through the Ontario portal takes about 1 to 2 hours once you have all your documents gathered. However, securing accurate property appraisals and bank letters can take 3 to 6 weeks, which is why you must start the valuation process the moment someone passes away. The Ministry of Finance generally has 4 years to audit your EIR, so you must keep all receipts and appraisals securely stored .

Frequently Asked Questions (FAQ)

Is the EIR the same as a CRA tax return?

No. The Estate Information Return is a provincial form submitted to the Ontario Ministry of Finance solely to verify probate fees. It has absolutely nothing to do with the federal terminal income tax return that you must file with the Canada Revenue Agency (CRA).

Can I ask the Ministry for an extension?

Generally, the Ministry of Finance does not formally grant extensions for the 90-day deadline before it expires. The legal expectation is that you file the best information you have by day 90, and then file an amended return when final values are confirmed.

What if I overpaid my probate tax?

If you complete your EIR and realize the actual value of the estate was lower than what you estimated at the courthouse, you can apply for a refund. You must file a specific refund request form with the Ministry of Finance after your EIR is processed.

Do I need to send my appraisals with the EIR?

No. You do not attach bank statements, property appraisals, or jewelry receipts to the EIR submission. However, you are legally required to keep these documents in your records in case the Ministry decides to audit your return.

Will I go to jail for filing late?

While the Estate Administration Tax Act technically includes provisions for imprisonment for severe tax evasion and fraud, simple administrative lateness is generally resolved through compliance (filing the late return) or monetary fines. Always seek legal advice if you are severely overdue.
