What are the rules for paying inheritance tax for green card holder living in US for 10 years and married to US citizen. I know that US citizens are exempt for an estate of 2 mill or less.
I paid inheritance tax in Japan do I have to prove how much I paid to the IRS?
Please let me know what you think and what IRS forms to quote or look at.
Thanks

If you inherited in Japan and paid those taxes, you are probably exempt from U.S. estate taxes to the extent that you paid to Japan, PLUS $2 million.

It depends. If the person inheriting it is a US citizen, it's basically straightforward and the same as the US situation. If the spouse inheriting it is NOT a US citizen, but is inheriting it from a US citizen spouse, it's not quite so straightforward.

I yield to TaxSearcher's greater knowledge and experience!
