TaxAct is good software up to a point. I have used it for some years to prepare 1040s. However, two issues arose this year that dragged me away from it. Firstly, they have issues with putting the correct codes on the 8949 and attaching a PDF. Secondly, depreciation does not always work properly, if an incorrect method was used at any point in the past and, if you override, you cannot e-file. There is no scope to prepare a 4562 by inputting numbers directly. Finally, this year they messed up the SEHI. It calculates correctly if you have PTC. In fact it does a really nice job. You just can't e-file it if you want the return to be correct.
As TaxAct said they were absolutely, totally, irrevocably correct when I asked about these issues, I decided to move to Drake. I will miss the ease of use in TaxAct. It is excellent software for the more basic returns and it did a good job at handling Oil & Gas K-1's when I had a client who bought and sold them on a regular basis. However, if you have business returns, or any of the issues noted above, you may find that it is lacking.
