Anybody know the cheapest site to file taxes. Help will be appreciated. 
How much does it cost as well ? 

 turbo tax online is free 

 Thanks, But it charges at the end before you e-file your taxes. 
Turbo tax fee - 19.99 and the refund processing fee - 29.99

I do not want to pay 50 dollar for that site. So was wondering if there is any.

Thanks for your comment though. 

 its free federal. check your local state website, they might also have free filing.

Go see your local H&R agent. They've doing specials until the 15th. $39.99 for state and federal (federal is free). Why do it on your own when you can have professionals do for such a meager fee? 

Thanks guys. 

All your comments are appreciated

Now a days Federal tax filing is free but they charge for state ( paper or efile). If you go through IRS web site, some may file free if you are qualify.
As Pepsi suggested: I am using TAXACT and paying only 13.95( 1 doller discount being returning client) regular is 14.95. But it will keep asking if you want to upgrade and if you choose to upgrade  then the price will go up.

 freetaxusa.com
federal: free
state: $9.95

enjoy

turbotax is the best.

 I have done online and done in the paper form, I like to do it in the paper form and mail it. I pay like 1 dollar all together for the postage. Easy and very small money. 

Still_Snake's suggestion is pretty legit, too. The downside is, your return will take extra weeks to get processed. Plus, there are chances of your returns getting lost/misplaced etc. 

 taxslayer.com is one of the best in the market IMO.

If you want to pay more : Good choice.

FYI : It is TURBO who gave a big refund filed fraudlent, could not catch in the begining.
