I sold some stocks and used the funds to invest in a Roth IRA and some mutual funds. Do I have to pay taxes on these funds that were rolled into other investments?

[DDollar · Accepted solution]

You have to report the sale of the investments that you sold.  If the net result was a gain, then YES, you have to pay capital gains tax.  If it is a net loss, you can use up to $3,000 to offset ordinary income, and carry over any remaining gain to offset future capital gains and/or reduce up to $3,000 per year against ordinary income. 

Your broker/dealer where you sold the stock is required to send you a Form 1099-B.  Form 1099-B is required to be mailed to you on or before February 15.  When you receive that form, enter it in TurboTax.  The interview will walk you through it.
