Q: Are the reinvested dividends and long and short term capital gains from an IRA or 401(k) taxable? What about gains if we buy and sell funds or if the funds go up in value or losses if we buy and sell funds or if the funds go down in value?
A: No, nothing that happens inside an IRA/401(k) has any tax consequences.
The only time taxes might be due on an IRA is when you make a withdrawal. That withdrawal amount is all then considered taxable income, unless your IRA was funded in part with after tax contributions.
