I have been using since it was called Tax Cut and now under the H&R Block franchise it continues to be robust but easy to use. It is excellent for rental property and investments and maintains loss carryforwards from year to year well if you stay with the application.
The tax program itself works well but it is the superficial stuff that is a problem. On a Mac, if you hit the save button, nothing happens. You have to go to the Mac header to actually save the return. Also, I tried to electronically file, but the return was rejected. It said I had to enter the prior year AGI. But there was no screen that allowed me to enter that number.
The federal program seems to be good, but the state program (Indiana) leaves a lot to be desired, and can't be trusted. This is the second year where Indiana DOR has recalculated my refund, and made significant changes. Last year, it was a refund reduction of almost $8000. This year it was a refund increase of almost $1500. Based on this experience, state programs, at least the Indiana program is not to be trusted to provide accurate results.
Since beginning to use H&R Block Taxcut software 15 years ago, my taxes have been consistently easier to do. I use the deluxe version which includes sections for rental properties (Schedule E) and sole proprietor businesses (Schedule C). Since the software can easily access past information from my previous filings it makes it simpler to complete the current return. Its quite possibly the easiest tax software I have used. Thanks H&R Block
After having used a competitor's tax preparation program for the better part of a decade (and, for the most part, being extremely satisfied with it), I had to find another solution a couple of years ago due to the competitor's inability to handle a non-SE 1099-Misc form. Thankfully, H&R Block software can handle this situation; however, I have found it to be lacking in other areas, such as projecting estimated tax payments for SE individuals. It is also *severely* lacking in state integration.
