Canadian advisors are often surprised to learn that a Canadian estate may have U.S. estate tax compliance obligations, even where the deceased was neither a U.S. citizen nor domiciled in the United States. Generally, if a Canadian resident dies owning U.S.-situs assets with a value exceeding US$60,000, the executor must file Form 706-NA. Whether U.S. estate tax is ultimately payable depends on the value of the U.S. assets, the size of the worldwide estate, and available relief under the Canada-United States Tax Convention.
From an estate administration perspective, many U.S. financial institutions will not release or transfer U.S. assets until the executor obtains an IRS Transfer Certificate (FTC). The FTC serves a function similar to a Canadian clearance certificate by confirming any U.S. federal estate tax liability has been satisfied or adequately secured.
To obtain the FTC, the executor must first file Form 706-NA within nine months of death (subject to a six-month extension if Form 4768 is filed on time). Only after the estate tax return has been reviewed can the IRS issue the FTC. Although the IRS indicates a processing time of approximately six to nine months, actual wait times are often longer. In an instance where no Form 706-NA filing is required, an FTC can still be requested by providing supporting documentation, including the will (or letters of administration), death certificate and affidavit prescribed by the IRS.
Executor’s Personal Liability: FTC Is Not a Full Release
Importantly, obtaining an FTC may not fully protect an executor from personal liability. Under IRC section 6324(a)(2) and related provisions, an executor or other fiduciary can be held personally liable if estate assets are distributed before U.S. tax liabilities are satisfied. The FTC primarily addresses the estate tax lien and facilitates the transfer of U.S. property, but it is not a comprehensive release from all potential fiduciary liability.
To obtain broader protection, the executor may seek a discharge from personal liability by filing Form 5495 (Request for Discharge from Personal Liability Under Internal Revenue Code Section 2204 or 6905). In addition, the executor may request an Estate Tax Closing Letter (Letter 627) as evidence that the IRS has accepted the estate tax return. The closing letter is generally available after the IRS has completed its review of Form 706-NA and may not be issued until many months after filing.
The practical lesson for Canadian executors is that obtaining a CRA clearance certificate alone may not be sufficient where U.S. assets are involved. Executors should carefully assess potential U.S. filing obligations early in the administration process and consider obtaining both an FTC and, where appropriate, a discharge from personal liability. Given the relatively low US$60,000 filing threshold and the potential for personal exposure under U.S. tax law, cross-border estates should be reviewed with experienced U.S. tax counsel promptly.
Conclusion
The IRS FTC is the closest equivalent to a Canadian clearance certificate, but unlike the Canadian regime, additional steps such as obtaining a discharge from personal liability and an estate tax closing letter may be necessary to fully protect the executor from future IRS claims. This reflects the fundamental U.S. principle that executors can remain personally liable for unpaid estate taxes if assets are distributed prematurely.
