Leaving your TFSA to a US spouse creates IRS reporting hell that might cost more than the inheritance itself.
Here's something nobody tells you at the bank: if you're married to an American and leave them your TFSA, you might be handing them a tax disaster. The IRS doesn't recognize TFSAs as retirement accounts, so your spouse inherits what looks like a foreign trust to American tax authorities. That means annual reporting requirements, potential penalties, and taxes on gains that were supposed to be tax-free.
The paperwork alone can cost thousands in accounting fees every year. Your spouse will need to file Form 3520 annually, report all income and gains, and potentially pay U.S. taxes on money that never should have been taxed. For a $50,000 TFSA, the compliance costs and taxes could eat up a chunk of the inheritance within a few years.
Cross-border tax specialists are increasingly recommending that Canadians with American spouses cash out their TFSAs before death and leave the proceeds as regular assets. Yes, you lose the tax-free growth for your final years, but you save your spouse from an administrative nightmare that could last decades.
