There is a strange thing that happens in a lot of households.
Someone knows their portfolio is wrong. Too much in one stock. A fund charging four times what it should. An allocation set during the Bush administration and never revisited.
They know. And they do nothing, for years, because of a sentence they half-remember about capital gains tax.
Here is the thing. If that portfolio is inside an IRA, there is no capital gains tax. There never was. The obstacle they have been respecting for a decade does not exist.
Yes, you can sell investments in an IRA without paying capital gains tax. All of them, today, at any profit, with no form to file and no line on your return.
So the interesting question is not whether you can. It is what you should do with a permission you did not know you had, and where the tax actually shows up instead.
