If you don't qualify for free tax preparation services and are not comfortable filing on your own, a commercial tax preparer is another option. But, be careful. Many companies will try to sell you extra services that you don't need.
Look out for any tax preparer who offers you an instant tax refund. This is actually a loan, which could cost you hundreds of dollars in fees. Anyone offering your tax refund in less than a week after filing may be charging you excessive fees for what is really a loan. It is much better to wait the extra week or so to get your full refund and avoid paying all of those fees.
