In some cases, the surviving US spouse may be better off inheriting the cash value of the TFSA rather than the account itself. The reason lies in the very different ways Canada and the United States treat TFSAs.
Why the United States treats TFSAs differently
In Canada, a TFSA is relatively straightforward: investment growth is tax-free, withdrawals are tax-free, and spouses can inherit the account seamlessly by appointing a successor trustee.
The United States, however, does not recognize a TFSA as a tax-free savings vehicle. Instead, the IRS generally considers it a foreign investment account that may trigger US tax and disclosure obligations.
That distinction is especially important if the TFSA holds Canadian mutual funds or exchange-traded funds (ETFs). Under US tax law, many of these investments are classified as Passive Foreign Investment Companies (PFICs), a category associated with complex reporting rules and potentially punitive tax treatment.
Because of these issues, many cross-border advisors are already warning Americans against holding TFSAs directly. But standard Canadian estate planning documents generally do not deal with transferring an account to a surviving spouse.
The true nature of life across the border
Consider London, a Canadian citizen living in Toronto, whose wife is a dual citizen of Canada and the US. Like many couples, London first named her spouse as the trustee instead of her TFSA, thinking it was the easiest and most tax-efficient option.
After speaking with a financial advisor, he learned that inheriting a TFSA could expose his wife to years of IRS reporting requirements and PFIC-related issues related to investments within the account.
Instead, London changed the name and named his wife as the beneficiary instead of the successor manager. That means he would receive the TFSA funds after his death, rather than inheriting the TFSA structure itself.

Why the status of a successor manager can cause problems
When a Canadian names a spouse as a substitute manager, the surviving spouse receives ownership of the TFSA and the account continues uninterrupted under Canadian tax law.
For married Canadians, that arrangement is generally fine. But for a spouse with US tax obligations, inheriting an account can mean inheriting years of cross-border reporting requirements, special PFIC filings, ongoing tax complexity, and potentially significant accounting costs.

The issue is not the TFSA balance itself. Continuous ownership of the account that the IRS handles very differently than in Canada.
Why beneficiary designations may work better
In many cross-border cases, advisors may choose to name a US spouse as a beneficiary rather than a successor trustee.
The difference sounds technical, but the result can be very different. The beneficiary receives the TFSA value after death, rather than continuing ownership of the TFSA account itself. That may allow the surviving spouse to move the assets to a more efficient structure from a US tax perspective.
This does not mean that the appointment of the next administration is always wrong. Transboundary planning rarely lends itself to universal laws; Citizenship, residency, investment, and broader geographic goals all matter.
The growing issue of families crossing borders
The broader issue highlights a growing reality for many Canadian families: housing planning forms designed for domestic situations do not always translate cleanly across borders.
