Great product. I have used TurboTax since 1998 and it consistently and accurately imports all necessary info from previous years and cuts down greatly what one needs to enter.
What's great about it: TurboTax walked me thru everything with concise questions that are easily understood.
What's not so great: only 1: when reviewing things on your own, it needs to come back to where you were in the list instead of top of list.
There should be a way to merge all DATA input from 2 single (for state filing) into 1 married for federal filing. without having to reenter all information.
This year was more difficult than in the past due to all the extra entries for foreign bank accounts and Financial Assets. During the form 1099 section for pension income the step by step did not ask me to prepare a substitute form for my UK pension. It led me straight to the 1099 form for my UK pension as if I had an actual 1099 form. I had to delete the UK entry and add a substitute form with that name. I note that this year the correct allocation of pension funds between the Canadian, UK and USA appears on the summary. Last year it was wrong on the summary but OK on the form. Since I have income from the UK, Canada and the USA with accounts and assets in all three countries I would never have been able to do the return without TT.
What's great about it: Handles foreign income and tax credit almost painlessly.
What's not so great: I had to correct 3 errors concerning missing statements for form 1116. The step by step process did not ask for these.
