We have used TurboTax.com for a few years. It is not as robust as the professional level tax preparation packages, but the low-cost and built in efiling are what has kept us using TurboTax.com for some of our returns. I am using a professional program to check the final results and make sure that there are no items missed on the final return. The interview method of TurboTax.com is difficult to navigate through quickly. Yet, bang for buck, TurboTax.com is an option.
