An estate administration tax checklist is most useful before an executor submits an Ontario probate application, not after. The tax is based on the value of estate assets that require probate, so an omitted account, unsupported valuation, or misunderstood exclusion can create delays, additional paperwork, and difficult conversations with beneficiaries.
For business owners and families, estate administration often involves more than a home and a bank account. There may be corporate shares, shareholder loans, real estate, investment accounts, equipment, insurance proceeds, or records that are not immediately available. A careful process protects the executor and helps ensure the estate meets its obligations accurately.
When Estate Administration Tax Applies
Estate Administration Tax, commonly called EAT, is an Ontario tax paid when an estate representative applies for a Certificate of Appointment of Estate Trustee, often referred to as probate. It is separate from the deceased person’s final income tax return, any trust returns, and taxes that may arise from selling estate assets.
The starting point is not simply everything the deceased owned. The relevant question is whether an asset was owned by the deceased at death and whether probate is required to deal with that asset. Financial institutions, land registry requirements, asset ownership structures, and the instructions in a will can all affect the answer.
Ontario generally calculates EAT at no tax on the first $50,000 of estate value and $15 for every $1,000, or part of $1,000, above that amount. Rates and rules can change, so the executor should confirm current requirements before filing. The tax must be paid when the application is submitted, which makes early cash-flow planning essential.
Estate Administration Tax Checklist: Gather the Right Records
Start with the date-of-death position. Create a file that records every asset, liability, ownership detail, and supporting document. This record should be organized enough that another professional, beneficiary, or court reviewer can understand how the estate value was determined.
Gather the original will and any codicils, the death certificate, recent bank and investment statements, property tax bills, mortgage statements, vehicle ownership records, insurance documents, and business records. If the deceased owned a private corporation, obtain the shareholder register, financial statements, corporate minute book, share certificates, and details of shareholder loans or amounts owed to the estate.
For each item, document four points: the asset description, its date-of-death value, how it was owned, and the evidence supporting the value. A spreadsheet can work well, provided the supporting documents are retained with it. Accuracy matters more than speed, but delaying the collection process can slow access to estate funds.
Identify assets commonly included
Assets that may need to be included in the estate value for probate purposes can include solely owned bank accounts, registered and non-registered investments without a named beneficiary, real property held solely by the deceased, vehicles, valuable personal property, and shares in a private company.
Business interests deserve particular care. A corporation is legally separate from its shareholder, so the estate may own shares rather than the corporation’s equipment, receivables, or bank balance directly. The value of those shares may require professional valuation support, especially when the business has goodwill, real estate, retained earnings, related-party transactions, or uncertain liabilities.
Review assets that may be excluded
Some property may pass outside the estate and may not require probate. Examples can include assets held in joint ownership with a right of survivorship, registered plans or insurance policies with valid named beneficiaries, and assets held in trust for another person.
These exclusions are not automatic. Joint ownership can be challenged, especially when an adult child was added to an account for convenience. A beneficiary designation may be missing, outdated, or ineffective. The executor should retain documents that support each exclusion rather than relying on an assumption that an asset is outside the estate.
Value Each Asset as of the Date of Death
Estate Administration Tax is based on date-of-death value, not the amount eventually received when an asset is sold. That distinction matters when markets move or a property sale occurs months later.
Bank balances are usually straightforward when supported by statements. Publicly traded investments generally require a reliable market value on the date of death. Real estate may need a qualified appraisal or other credible valuation evidence, particularly if it is a rental property, farm property, recreational property, or property connected to a business.
For personal property, use a realistic fair market value. Jewelry, artwork, collections, machinery, and specialty vehicles may need an appraisal when their value is significant. Do not use an insured replacement value unless it fairly reflects what the item could have sold for on the relevant date.
Private company shares are often the most complex estate asset. The book value shown in year-end financial statements may not be the fair market value. An accountant can help assemble current financial information, while a qualified business valuator may be appropriate where the value is material or likely to be disputed.
Calculate the Tax and Plan for Payment
Once included assets have been identified and valued, total the estate value and calculate EAT using the current Ontario rate. Keep a clear calculation sheet in the estate file. It should show the total included value, the tax-free threshold, the taxable amount, and the final tax payable.
The practical challenge is that an estate can be valuable but short on cash. A home, private company shares, or investment account may be included in the estate value even when the executor cannot immediately access or sell the asset. Before filing, identify available cash, review whether an estate account can be opened, and consider how the tax and early estate expenses will be funded.
Executors should not use personal funds casually without documenting the payment. If an executor advances money, keep proof of payment and record whether it is an estate expense to be reimbursed. Good records reduce confusion when preparing accounts for beneficiaries.
File the Application and Keep Supporting Evidence
The probate application requires the estate representative to provide information about the estate’s value. After the Certificate of Appointment is issued, Ontario also requires an Estate Information Return within the applicable deadline. This return provides more detailed information about estate assets and values.
The Estate Information Return should agree with the probate application unless there is a clear and documented reason for a difference. If new information changes the estate value, the executor may need to amend the filing and pay additional tax, or request a reassessment where appropriate.
Keep valuation reports, account statements, ownership documents, correspondence with financial institutions, and calculations for the required retention period. An executor’s role carries personal responsibility. A well-supported file is one of the best protections if questions arise later from beneficiaries or tax authorities.
Do Not Confuse Probate Tax With Income Tax
Paying Estate Administration Tax does not complete the estate’s tax work. The executor may still need to file the deceased person’s final income tax return, optional returns where beneficial, trust returns for the estate, and returns for a corporation owned by the deceased.
There can also be tax consequences from a deemed disposition of capital property at death, registered plan income, business succession arrangements, and post-death asset sales. For an incorporated professional or owner-managed business, the estate plan and corporate tax position may be closely connected. Probate planning that ignores income tax can solve one administrative issue while creating a larger tax cost elsewhere.
A coordinated review of legal documents, bookkeeping records, corporate information, and tax filings helps the executor make decisions with a full picture of the estate.
When Professional Support Is Worth It
Simple estates can often be organized efficiently with careful recordkeeping. Professional support becomes especially valuable when the estate owns private company shares, multiple properties, a farm, a partnership interest, assets in more than one province, or accounts with unclear ownership.
It is also wise to seek guidance when there is a dispute over joint assets, a missing beneficiary designation, incomplete books and records, or uncertainty about asset values. Legal advice addresses probate and executor duties, while accounting support can help establish reliable valuations, organize financial records, calculate tax-related obligations, and prepare required tax filings.
WiseWealth Accountancy Services can help executors and families bring order to financial records, clarify tax reporting obligations, and maintain accurate documentation during estate administration. The goal is not simply to complete forms. It is to give the executor a clear, defensible financial record while allowing the family to focus on the responsibilities that matter most.
