Various ways to file US Tax returns

These are the options that I came across. Better to have alternatives. Can take estimates from different sources and go with the best option.

1. IBSN – Will charge you 80$ for State and Federal Tax filing and an additional 12.5% on extra returns that we get beyond the default. Need to schedule an interview online to give all the expense details.
2. H&RBlock – Can take an appointment with Uma Pansari (a consultant in H&RBlock) to file the tax. Charges you around 82$ and probably an additional charge on extra returns which we get.
3. Turbo Tax - Federal tax filing is free and state tax filing costs around 25$.
4. Tax Act – Both the federal and state tax cost around 13$. Requires US based IDs like driving license or state ID or US Passport.
