Colorado source income is income derived from a business that operates in Colorado or from tangible real or personal assets located in Colorado. Stocks and bonds are intangible assets and therefore the income from them has no "source". CO nonresidents do not have to file a CO income tax return if the investment club is their only income that has any "connection" to CO.

Even if we sell stock at a profit, that's still not
considered Colorado income?  If there's no income, do non
residents still need to file a Colorado State return with it
$0?
