For the U.S. only: There are several "unusual" issues with estate taxes and retirement accounts.
3. If the "surviving" spouse is not a U.S. citizen and not a U.S. resident and dies with assets in the U.S. huge estate taxes may be owed. There is only a $60,000 deductible for non U.S. citizen, non U.S. residents on estate taxes. The U.S. estate tax rate is high; something like 40% - 50%. (U.S. citizens and U.S. residents get a $5M+ deductible on estate taxes.)
The operative word in the above quote is
may. In many cases the threat of crushing U.S. estate taxes is more illusory than real. In many cases, there is a treaty that mitigates. For example, for Canadians, the situation (as described in a January 2018 tax bulletin) works thus:
If your US assets are $60,000 or less If the value of your US assets are $60,000 or less, you are not subject to US estate tax and your estate does not need to file a US estate tax return.
If your US assets exceed $60,000 and your worldwide estate exceeds $11.2 millionIf the value of your worldwide assets exceeds $11.2 million, you may be required to pay US estate tax based on the value of your US assets. The tax rate starts at 18% and increases to 40% for US assets exceeding $1 million.
Fortunately, Canada’s tax treaty with the United States provides some relief for Canadians. It allows you to reduce your estate tax liability by claiming a tax credit equal to the greater of:
• $13,000• $4,425,8002 x the value of your US assets ÷ value of your worldwide assetsFor example, if your US stock portfolio accounts for 10% of the value of your worldwide assets, you will be entitled to a credit of $442,580 ($4,425,800 x 10%).
US estate tax rates and credits The creditsFor example, David, a Canadian resident (who is not a US citizen), owns a US stock portfolio worth $1.5 million. His entire estate is valued at $15 million.
As shown below, if David dies in 2018, his estate can claim a unified credit equal to $442,580 (10% of $4,425,800), reducing his estate tax liability to $103,220.
What if David dies in 2018?US estate tax before credits

US estate tax liability after unified and marital credits
Nil
In addition to the unified credit, the tax treaty provides a marital credit if the US assets pass to a spouse on death. The marital credit equals the lesser of the unified credit and the amount of the estate tax.
If David were to leave the US stock portfolio to his wife Kylie, also a Canadian resident (who is not a US citizen), his US estate tax liability would be completely eliminated.
As a Canadian, owning U.S. real estate I intend to leave to my wife (also a Canadian citizen, who came here from the Phils with me in 2002), I pay considerable attention to and keep up to date on this stuff. I am working diligently to keep my worldwide assets under the $11.2 million threshold. It's a struggle, but I think I can do it.
