Tax for sold mutual funds and stocks in non-retirement accounts.

Assume that I sold some mutual funds and stocks, however never withdrew money out of the brokerage account. Do I still need to pay taxes on the gain (note that I have not withdrawn the gain yet.) ? I re-invested the money sold and earned more on them.
Also, my broker has not sent me any 1099 form for these transactions. Please advice.

If you had a Gain/Loss on the Sale of Stocks, you can report this in your return without a 1099-B.

However, if you can go into your brokerage account online, you may be able to print a 1099-B from their site, or at least a Brokerage Statement detailing the Sales Info.

Or, you may be able to import your financial info from your broker directly into TurboTax, if your broker is a TurboTax Partner.   Click this link for info on How to Import Financial Transactions. 

Whether you have withdrawn or reinvested the gain does not affect your reporting requirement.

yes, unfortunately you still need to pay taxes. it is considered as again even though you invested it back.
