I've been using TurboTax since 1994! It has proven to be very accurate and reliable. The interface has continuously improved every year. I think I has difficulty with a version a couple years ago where some of the prompted questions were difficult to answer. I would love for TurboTax to have a "more information" on "every" question for those situations. Because of financial reasons this year, I almost switched tax software. After completing my taxes with this other software (that ranked in the top 3) not only did not know what do with a W2 form entry but I ended up owing. I couldn't find where my property tax entree went to and why it wasn't being calculated. I panicked and bought my TurboTax! I'm glad I didn't switch this year! Thank you TurboTax for my refund!!!
What's great about it: Reliability
What's not so great: Some questions I wasn't clear how to answer
Could not contact a agent with questions, only a FAQ that didn't come close to answering the question. When it imported my 1099-div it didn't bring all of the information it needed to complete my taxes.
What's great about it: It worked well in spots, save time and checked for errors.
I have Aquila Tax Free Fund of Utah. Turbo never accepted the tax exempt entry correctly. It wanted to tax the exempt interest. You need to check on this. Why bother with a tax free fund if it isn't tax free?
Turbotax walks me through the process and gives advice for the upcoming year. Coupling with ItsDeductible helps make my tax return complete. It was more accurate than H&R Block which made mistakes 2 years in a row.
What's great about it: Easy to use
What's not so great: nothing
Pros: My job status changed this year (switched jobs, lost a job, got a raise or promotion), I bought or sold investments
