Do taxes without 1099-b on hand?

[nick112207]

So this year I did some playing in the stock market. Nothing fancy, just buying and selling regular stocks, all sales being short term capital gains.

I typically file my taxes way before the broker release date of 2/15. 

Since I can see my total gains and deferred losses can I just input that info, or is there more stuff on that form I'll be missing?

There may be more financial information on your 1099-B so wait until you receive the official tax document before filing. Once it's available, you may be able to import your trades into TurboTax.

You can do that, but only if you know what you're doing.  Even the, you shouldn't.  It's too easy to make a mistake that will waive a red flag at the IRS.
