How to Pass Your TFSA to Heirs Without Triggering Tax on Post-Death Growth
A $150,000 TFSA that grows to $165,000 between the date of death and the day the bank finally processes the paperwork will hand the recipient a $15,000 taxable income slip unless the account was set up correctly. Most people name a beneficiary and think they're done. They're leaving money on the table.
The Successor Holder Designation Is the Only Complete Fix
Only a spouse or common-law partner qualifies. The designation appears on the TFSA application itself, not in your will. When you name your spouse as Successor Holder, they inherit the account intact. The TFSA keeps its tax-sheltered status. Every dollar of growth after your death remains tax-free, whether that growth happens in a week or a year.
If your spouse is named as a beneficiary instead, they receive the fair market value at the date of death tax-free, but the account closes. Anything earned between death and distribution gets reported on a T4A and taxed as income. In a volatile market or a slow-moving estate, that difference costs real money.
A successor holder also doesn't use their own TFSA contribution room. If your spouse has already maxed out their $109,000 cumulative limit as of 2026, they can still take over your account in full. That's two TFSA pots compounding tax-free under one roof.
If the TFSA is held at a bank or brokerage, Quebec law ignores the beneficiary field on the account form. You must name the recipient in your will. The exception: TFSAs structured as insurance contracts, such as segregated funds. Those allow direct beneficiary naming.
For residents of other provinces, the account-level designation overrides anything in the will, even if the will says something different. Courts have ruled on this repeatedly. The form at the institution is what counts.
Naming Anyone Other Than a Spouse Creates a Tax Window
A child, sibling, or parent named as beneficiary receives the account's value at death tax-free. But the day after death, the TFSA effectively becomes a taxable investment account until the funds are distributed. If markets rise, the gain is taxable income to the beneficiary. If markets fall, the loss cannot be claimed.
The institution will issue a T4A for any post-death earnings. The beneficiary reports it as income in the year received. There is no way around this once the original holder dies and the account loses its tax-exempt status.
Skip Probate by Naming Someone Directly
Leaving the TFSA to "Estate" instead of naming a specific person subjects the full balance to provincial probate fees. In Ontario, that's $15 per $1,000 over $50,000. A $100,000 account pays $750 in probate, and the process can stretch six to twelve months.
Name a beneficiary or successor holder on the account form and the funds bypass probate entirely. The institution pays out directly once they receive a death certificate.
The Deadline for Spouse Transfers Without Using Contribution Room
If your spouse is named as a beneficiary rather than successor holder, they can still roll the TFSA value into their own account without using up their contribution room, but only if the transfer is completed by December 31 of the year following the year of death. Miss that window and the contribution uses their available room or triggers the 1% per month penalty if they're already maxed out.
The spouse must file Form RC240, Designation of an Exempt Contribution, with the transfer. The bank won't do this automatically.
A successor holder designation sidesteps all of this. One signature on the original application saves the executor hours of forms and removes the risk of a missed deadline or a surprise tax bill on gains the heirs never expected.
