What Happens to a $300,000 TFSA When You Die in Ontario in 2026: Successor Holder vs. Beneficiary and the Probate Trap That Costs Estates $7,500

The Scenario: $300,000 TFSA, Oakville Couple, One Spouse Dies at 74

Margaret, 74, dies in April 2026 in Oakville, Ontario. She has been contributing to her TFSA since 2009 and the account holds $300,000. Her husband David, 72, survives. Two adult children: Karen (48) and Michael (45). Both financially independent.

The principal residence qualifies for the PRE — no capital gains tax. The non-registered savings pass to David by right of survivorship outside the estate. The TFSA is where the planning decision makes a $4,500+ difference.

Path 1: Successor Holder — The Only Path That Preserves Everything

A successor holder is someone who becomes the new holder of the TFSA when the original holder dies. The account does not close. The investments stay in place. The tax-free status continues.

When Margaret names David as successor holder on her TFSA contract at the financial institution, here is what happens at her death:

The TFSA room advantage: David now holds $409,000 in tax-free accounts

This is the part most people miss. When David becomes successor holder, he does not “use up” any of his own TFSA contribution room. His cumulative room since 2009 is $109,000 (2026 limit). Margaret's inherited TFSA is a separate account on top of that. David now has:

• His own TFSA: up to $109,000
• Margaret's inherited TFSA: $300,000
• Combined tax-sheltered TFSA capacity: $409,000

If David had received the $300,000 as a beneficiary instead (Path 2), he would only be able to re-shelter whatever room he has left in his own TFSA. If he already has $90,000 in his own TFSA, that leaves $19,000 of room. The other $281,000 sits in a taxable account. The successor holder designation is worth tens of thousands in future tax-free growth. For the full mechanics of this distinction, see our TFSA successor holder vs. beneficiary guide.

Path 2: Named Beneficiary — Tax-Free at Death, Taxable After

If Margaret names Karen and Michael as beneficiaries on her TFSA contract (not successor holders — they can't be, because they're not her spouse), the TFSA is collapsed at death and the proceeds are paid out as cash.

The post-death growth trap

Between Margaret's death and the date the TFSA is actually closed and paid out, the investments inside the TFSA continue to earn returns. That growth is no longer tax-free. CRA treats it as taxable income in the hands of the beneficiary.

The critical point: the beneficiary designation must be on the TFSA contract itself at the financial institution. Ontario's Succession Law Reform Act allows beneficiary designations on TFSAs, but if the designation is only in the will (not on the contract), the TFSA proceeds flow through the estate and probate applies. This is the most common documentation mistake in Ontario estate planning.

Path 3: No Designation — The $4,500 Probate Trap

If Margaret never designated anyone — no successor holder, no beneficiary — the TFSA falls into her estate by default. This is the worst outcome.

Ontario Estate Administration Tax: the calculation

Ontario charges $0 on the first $50,000 of estate value, then $15 per $1,000 (1.5%) on everything above $50,000. Margaret's estate without the TFSA: $650,000 home going through the will. With the TFSA: $950,000 through the will ($650K home + $300K TFSA — the joint savings bypass the estate).

That $4,500 is pure waste. The TFSA was designed to be tax-free. The money was already taxed before it went in. And now Ontario's Estate Administration Tax takes 1.5% of it on the way out — because no one filled out a form at the bank.

The Three Paths Side-by-Side: $300,000 Ontario TFSA

What Happens to the Survivor's TFSA Room: The Most Misunderstood Rule

When David receives Margaret's $300,000 TFSA as successor holder, a common fear is that it “uses up” his own TFSA room. It does not. The successor holder transfer is entirely separate from David's own TFSA contributions.

David's TFSA capacity after the transfer:

The $7,000 annual TFSA contribution limit in 2026 (cumulative $109,000 since 2009) applies only to David's own contributions to his own TFSA. The inherited TFSA is a separate bucket with its own history. He cannot add new money to it, but the existing $300,000 grows and compounds tax-free indefinitely.

Income After Death: CRA's Treatment of Post-Death TFSA Growth

CRA distinguishes between two periods for a TFSA after the holder's death:

CRA considers the TFSA to exist until the earliest of: (a) the successor holder is recognized as the new holder, (b) the last payment is made from the account, or (c) December 31 of the year following the year of death. For Margaret's April 2026 death, the outer deadline is December 31, 2027.

The longer the estate takes to wind up the TFSA, the more post-death growth accumulates — and the higher the tax bill for beneficiaries or the estate. A successor holder designation eliminates this entirely. The account never closes.

Province-by-Province Probate on a $300,000 TFSA Entering the Estate

Ontario's 1.5% EAT is among the highest probate rates in Canada. Here is what the same $300,000 TFSA would cost in probate across provinces if it enters the estate:

In Ontario, BC, and Nova Scotia, a missing TFSA designation is a four-figure mistake. In Alberta, Manitoba, and Quebec, probate is negligible regardless. But the post-death growth tax applies everywhere — it's federal, not provincial. The successor holder designation avoids both costs in every province. For the full provincial comparison, see our probate fees Canada 2026 guide.

Common Mistakes: Why Estates Lose $4,500+ on a Tax-Free Account

Mistake 1: Putting the designation in the will instead of on the TFSA contract

Ontario's Succession Law Reform Act allows beneficiary designations on TFSAs in the will. But if the designation is only in the will, the TFSA must go through probate to reach the beneficiary. The designation needs to be on the TFSA contract at the financial institution for the money to flow directly to the beneficiary or successor holder outside the estate.

Mistake 2: Naming a spouse as “beneficiary” when you mean “successor holder”

These are different designations with different consequences. A spouse named as beneficiary receives a cash payout — the account closes, post-death growth is taxable, and they can only re-shelter into their own TFSA room. A spouse named as successor holder keeps the account alive. Many financial institution forms have separate checkboxes or fields for each. Choosing the wrong one on the form costs the family the entire room-preservation benefit.

Mistake 3: Assuming the TFSA “just goes to my spouse” without a designation

TFSAs do not automatically transfer to the surviving spouse. Unlike joint bank accounts with right of survivorship, a TFSA is individually held. Without a successor holder or beneficiary designation, the TFSA enters the estate and goes through probate regardless of what the will says about the spouse inheriting everything.

Mistake 4: Not updating designations after a divorce or second marriage

In Ontario, a divorce does not automatically revoke a beneficiary designation on a TFSA. If Margaret designated her ex-husband as successor holder 15 years ago and never updated the form after remarrying David, the ex-husband could become the successor holder at Margaret's death. The TFSA contract designation overrides the will. Review all registered account designations after any major life event. For estate planning in blended families, see our Ontario blended family estate guide.

The Best Practice: Dual Designation (Successor Holder + Contingent Beneficiary)

Name your spouse as successor holder on the TFSA contract. Then name your adult children as contingent beneficiaries. Here is why this works:

• If your spouse survives you: the successor holder designation activates. TFSA transfers to them. The beneficiary designation is ignored.
• If your spouse predeceases you (or dies simultaneously): there is no surviving successor holder, so the contingent beneficiary designation activates. The TFSA is paid out directly to your children, bypassing the estate and avoiding Ontario's 1.5% probate.
• If neither designation existed: the TFSA enters the estate by default. Probate applies. This is the scenario we're trying to prevent.

The dual designation costs nothing and takes 10 minutes at the bank. It covers both the expected scenario (spouse survives) and the unexpected one (spouse doesn't). For the broader estate planning context, see our inheritance tax Canada 2026 guide.
