Key takeaways
  • If you distribute estate property without a clearance certificate and tax is owing, you can be personally liable up to the value distributed.
  • Late returns bring percentage penalties and interest, and a late T3 can bring a daily penalty.
  • A clearance certificate shifts liability for reported tax from you to the estate and those who received the assets.
  • Careful records and early legal advice are your best protection, because many liability questions depend on the facts.

Being named executor, or acting as estate trustee, can feel like signing up for a risk you did not choose. You may worry that a wrong payment to a beneficiary, a missed tax return or an overlooked debt will come out of your own pocket.

Some risks are real and are set out in statute, particularly around income tax. Others depend on the facts and on the will. This article walks through the points that are clearly spelled out and the habits that reduce your exposure. It is general information, and a lawyer can tell you how it applies to your estate.

Where personal liability usually comes from

Whether you could be personally responsible for a particular mistake depends on the facts and on the will, so it is worth confirming with a lawyer. The best documented example in the tax rules is distributing before getting a clearance certificate. If tax is owing, the representative is personally liable for those amounts to the extent of the value of the property distributed.

Other areas, such as paying the wrong beneficiary or favouring one creditor, depend on the will, the facts and Ontario law beyond what is covered here. Treat those as questions for a lawyer before you act, not after.

Tax mistakes and their cost

Tax errors are the most common avoidable ones, because the deadlines are firm. The table shows the main exposure points.

MistakeConsequence
Final T1 filed latePenalty of 5% of the balance owing plus 1% for each full month late, up to 12 months, and interest on the balance and penalty
Balance not paid by the payment datePayment is due even if a later filing date applies
Estate T3 filed latePossible penalty of $25 a day, minimum $100 and maximum $2,500, even if nothing is owing
Distribution without clearancePersonal liability up to the value distributed
Estate Information Return not filedFine of at least $1,000 and up to twice the tax payable, and/or imprisonment up to two years

The penalty may be higher if a late-filing penalty was assessed for any of the 3 previous tax years.

Know the deadlines that trip people up

A final return for a death between January 1 and October 31 is due April 30 of the following year, and for a death between November 1 and December 31 it is due 6 months after death. If the deceased or a spouse or partner ran a business, the filing date can be later, but the balance owing is still due on the earlier payment date.

Registered plans can surprise people. For an unmatured RRSP, the fair market value of the plan is included in the deceased's income on the return for the year of death. That tax is taxed on the final return, whoever receives the money. If you pay out the estate without allowing for that tax, you may have no funds left to pay it.

There may be a way to shift part of that tax to a qualifying survivor, such as a spouse or common-law partner, through a refund of premiums. Ask an accountant or lawyer early, because the paperwork needs both of you.

How a clearance certificate protects you

A clearance certificate confirms the estate has paid all income tax, interest and penalties owed when it is issued, or that the Minister has accepted security. Once it is issued, liability rests with the estate or trust and the beneficiaries or others who received the assets rather than with the representative.

It is not a one-time shield for everything. If new assets or property affecting reported income or capital gains are found later, another certificate is needed before you distribute those assets. And it takes time: CRA acknowledges within 45 days, and assessment can take up to 120 days if all documents are provided.

What to do next

Frequently asked questions

Can I really be personally liable for the deceased's taxes?

Yes, in one clear situation: if you distribute property without a clearance certificate and tax is owing, you are personally liable up to the value of what you distributed. Getting the certificate first is the protection.

Does a clearance certificate cover everything?

It covers the income tax position at the time it is issued. If new assets or property that affects reported income or capital gains are found later, you need another certificate before distributing them.

What if I file the final return late?

A penalty applies of 5% of the balance owing plus 1% of the balance for each full month late, up to 12 months, with interest on the balance and the penalty. File as soon as you can and ask an accountant about your position.

Can I be fined for the estate information return?

Failing to file it, or making false statements, can bring a fine of at least $1,000 and up to twice the tax payable, and/or imprisonment up to two years. It must be filed within 180 calendar days after the certificate is issued, even if the value is $0.
