Being named executor means you step into the deceased's shoes with the Canada Revenue Agency (CRA), and you can be personally liable if you distribute the estate before CRA is satisfied. Here is the tax side in the order it tends to unfold: who to call first, which returns to file, the traps that catch families by surprise, and how to get the clearance certificate that protects you.
Start with the simplest question: did the deceased have an accountant?
If so, call that firm before you do anything else. An accountant who has prepared the last several returns already knows what the deceased owned, which slips arrive every year, whether there is a private corporation, whether the principal residence was ever rented, and whether any capital losses are sitting unused. That history can save weeks of detective work and real fees.
If there was no accountant, you are rebuilding the picture from scratch. Start by gathering:
- The last three years of Notices of Assessment, which show contribution room, carried-forward losses and any outstanding balances.
- Bank, investment, RRSP, RRIF and TFSA statements, including the balance on the date of death.
- Property records: deeds, purchase documents and, where possible, a valuation of any real estate at the date of death.
- Corporate records if the deceased owned shares in a private company: minute books, shareholder agreements and the most recent financial statements.
- Insurance policies, pension statements and the will.
One of your first calls should be to CRA. Notify it of the death and provide proof that you are the legal representative, such as the death certificate and the will or the court appointment. Once CRA has recorded you as the legal representative on the deceased's account, you can authorize an accountant, lawyer or other tax representative to access the account, and assign or change that access as new advisors come on board, through Represent a Client or on paper with Form AUT-01. Do not sign into the deceased's own CRA account using their credentials; the legal representative's access is set up separately.
Which returns you may need to file, and when
The final T1 return is the one everyone expects, but it is rarely the only one. Depending on the estate, you may be responsible for several filings, some of them optional and able to reduce the total tax paid. Deadlines depend on the date of death.
| Return | What it covers | Due date |
|---|
| Final T1 (death Jan 1 to Oct 31) | Income and deemed gains from January 1 to the date of death | April 30 of the following year, for both filing and payment |
| Final T1 (death Nov 1 to Dec 31) | Same | Six months after death, for both filing and payment |
| Final T1 with a business | Deceased or their spouse was running a business at death | Filing June 15 of the following year (death Jan 1 to Dec 15); payment is still April 30 |
| Rights or things return | Income earned but not yet paid at death, such as final wages or unpaid dividends | Later of one year after death or 90 days after the final return's assessment |
| Proprietor or partner return | Business income from the fiscal year-end to the date of death | Same as the final T1 |
| Graduated rate estate return | Certain income from another estate | Same as the final T1 |
| Prior-year T1s | Any year before death that was never filed | As soon as possible |
| T3 estate return | Income the estate earns after death | 90 days after the estate's year-end |
Two points deserve attention. The optional returns split income across separate returns so that each benefits from its own personal credits and lower brackets, which often reduces the total tax. And the penalty for filing late with a balance owing is 5% of the balance plus 1% for each full month late, up to 12 months, with interest compounding daily. Missing the date by a few weeks while the family sorts out paperwork is the most expensive avoidable mistake we see.
Deemed dispositions and the principal residence
For tax purposes, death is treated as a sale. The deceased is deemed to have disposed of all capital property immediately before death at fair market value, and any gain or loss goes on Schedule 3 of the final return. That includes cottages, rental properties, non-registered investments and private company shares, even though nothing was sold and no cash changed hands. The estate can face a large tax bill with no sale proceeds yet available to pay it, so liquidity planning matters early.
- Spousal rollover. Property passing to a surviving spouse or common-law partner who was a Canadian resident can transfer at the deceased's cost, deferring the gain until the spouse sells or dies. The property must vest indefeasibly in the spouse within 36 months of death. A qualifying testamentary spousal trust works the same way. The executor can elect out of the rollover property by property, which is sometimes useful for using up capital losses or lower brackets.
- Capital losses in the final year. Net capital losses in the year of death, and unused ones from earlier years, can offset other income, not just capital gains, which is not allowed in any other year.
- Records of cost and value. Fair market value at death and adjusted cost base drive everything. Get date-of-death valuations for real estate and private company shares while the evidence is fresh.
The principal residence deserves its own question: did the deceased own one? A gain on a qualifying home can be fully exempt, but the exemption is not automatic. The executor must report the disposition and designate the property on the final return using Form T1255, along with Schedule 3, even when the entire gain is exempt. Where the home passes to a spouse or spousal trust on a rollover, the designation is not required, but keep records of the years the home qualified. Watch for a home that was partly rented, a second property such as a cottage that might compete for the designation, and land beyond roughly half a hectare.
RRSPs and RRIFs: the biggest tax bill nobody expects
Registered plans do not escape tax at death. Unless a rollover applies, the full fair market value of an unmatured RRSP is included in the deceased's income in the year of death, reported on line 12900 of the final return and shown on the T4RSP. A RRIF works the same way, reported on a T4RIF. A $400,000 RRIF paid to an adult child can push the final return into the top bracket, and the tax is owed by the estate even if the money goes directly to the beneficiary.
- Spousal rollover. If a spouse or common-law partner is the beneficiary, the plan can generally move to their RRSP or RRIF without tax in the year of death, and the spouse reports the income later as it is withdrawn.
- Financially dependent children and grandchildren. A rollover is available in limited cases, such as a transfer to a registered disability savings plan for a child or grandchild who was financially dependent because of an impairment.
- Who bears the tax. When a named beneficiary other than the spouse receives the funds directly, the tax lands on the final return, which reduces what is left for everyone else. Beneficiaries who expected the full balance are often surprised, so review the will and the designations together.
- Post-death growth. Growth after death is taxed to whoever receives it. If the value drops after death, the executor may be able to claim a deduction on the final return, generally if the final distribution happens by the end of the year following death.
- Beneficiary designations. Check what the plan documents actually say, because a designation on the plan can override the will.
TFSAs are a pleasant contrast: the balance at death is tax-free, though income earned after death is taxable unless the account passes to a spouse as a successor holder.
If the deceased owned a corporation
A private corporation adds a second layer of planning, and the executor has real decisions to make. The shares are deemed sold at fair market value at death, so the value of the company has to be established, and the corporation continues to exist with its own filing obligations until it is wound up or sold.
The central issue is double tax. On death the shares are taxed once as a deemed capital gain on the final return. If the company then pays out its remaining assets to the estate as a dividend, the same value can be taxed again. Several tools reduce the overlap:
- Loss carryback (subsection 164(6)). If the estate qualifies as a graduated rate estate and the shares are redeemed or wound up within the estate's first taxation year, the resulting capital loss can be carried back to the final return to offset the deemed gain. The timing is strict, so plan the wind-up early.
- Pipeline planning. In some situations the estate transfers the shares to a new holding company in exchange for a note, so funds can flow out as a return of capital rather than a dividend. This is technical and needs advance planning.
- Capital dividend account. Any tax-free balance in the account, including the non-taxable half of capital gains and life insurance proceeds received by the company, can be paid out as a tax-free capital dividend if the election is filed properly.
On the corporate side, the company still needs to file T2 and GST/HST returns, make payroll remittances and keep the minute book current until it is dissolved. Winding up a corporation also requires its own clearance certificate before property is distributed, separate from the estate's. Where a surviving shareholder, a buy-sell agreement or a corporate-owned insurance policy is involved, bring in your lawyer and accountant before anyone signs anything.
Life insurance: usually tax-free, with a few exceptions
Proceeds paid to a named beneficiary are generally received tax-free and are not reported on the final return. With a named beneficiary they also typically bypass the estate, so they are not subject to probate fees or the estate's creditors. The executor still needs to know what policies exist, because beneficiaries often depend on the executor to find them and file the claims.
- Estate as beneficiary. The proceeds fall into the estate, are available to creditors and may attract probate fees, although they remain tax-free.
- Policies with cash value. If the deceased owned a policy on someone else's life, or a policy with a cash surrender value, there can be a deemed disposition and a taxable policy gain.
- Corporate-owned policies. When the company owns the policy and receives the proceeds, the amount less the policy's adjusted cost basis is added to the capital dividend account and can be paid to shareholders tax-free. Missing that election leaves value on the table, so loop in the corporate accountant.
- Interest after death. Interest the insurer pays on the proceeds from the date of death is taxable to the recipient.
A practical tip: search the deceased's mail, bank statements and safe deposit box for policy statements, since group coverage through an employer or a credit card is often forgotten.
The clearance certificate: your protection as executor
A clearance certificate is CRA's confirmation that the estate has paid the income tax, interest and penalties owing at the time it is issued. Without one, an executor who distributes assets can be personally liable for unpaid federal tax, up to the value of what was distributed. With one, the liability moves to the estate and the beneficiaries who received the assets. The sequence matters:
- File all the returns: final T1, any optional returns, prior-year returns and the estate's T3 returns.
- Wait for the Notices of Assessment, and pay or secure everything owing.
- Only then submit Form TX19, Asking for a Clearance Certificate, with the will or appointment documents, a list of assets with cost and fair market value, and a proposed distribution. If the deceased had a GST/HST number, Form GST352 is also needed.
- Authorize your accountant or lawyer to receive CRA correspondence, then submit online through Represent a Client or My Account, or by mail or fax to your tax services office.
Do not file the clearance request together with the returns. CRA warns that doing so delays the assessment of those returns. Expect an acknowledgement letter within 45 days and a decision within about 120 days once CRA has everything, so build that time into the estate timeline. If the wait goes past 120 days, call CRA.
Two cautionsThe certificate covers only what CRA knew at the time, so if new assets surface later you will need another one before distributing them. It also protects against federal tax debts only: provincial obligations, such as the estate administration tax, still need their own attention.
Common mistakes, and a checklist for the first 90 days
The errors we see most often are all avoidable: distributing funds before the clearance certificate arrives, missing the principal residence designation, forgetting that a RRIF or RRSP is taxable on the final return, letting a corporation sit unattended, filing the final return late, and filing the clearance request alongside the returns.
- Obtain several certified copies of the death certificate and locate the will.
- Confirm your authority as executor, then contact CRA to be authorized as legal representative on the deceased's account so you can assign access to tax representatives.
- Contact the deceased's accountant, or begin gathering three years of returns and assessments.
- Note the date of death and calendar the final return deadline.
- Inventory assets and get date-of-death values for real estate and private shares.
- Confirm beneficiary designations on RRSPs, RRIFs, TFSAs and insurance.
- Identify whether a principal residence exists and who inherits it.
- Review corporate holdings and book a call with the corporate accountant.
- Open an estate bank account and keep every receipt.
- Hold back enough to pay the final tax bill before making any distribution.
