Everywhere I read. I get that the capital gain for nonresident who lived in the US for more than 183 days is at 30% fixed rate unless the treaty defines a different rate. However, my software (ProConnect by Intuit) produced an error that says "For efile purposes, capital gain on Schedule NEC, Line 9, 30% column, is not allowed." This happened to countries such as Singapore that do not have a treaty with the US, for countries that do such as Japan, China, France, Canada, the error disappears. I am wondering if it is a bug in the software, or I did something wrong.
This is to report stock again for nonresidents on schedule NEC of form 1040-NR.
Thanks.
