After discovering that TurboTax does not have a Mac version for business tax returns, I found PDFfiller and it is a great alternative. It is much more reasonable and includes all the forms needed to file my return.

Best software for PDF editing! My non-profit radio station has been more productive than ever before with PDFfiller! An user-friendly web app able to do much more than you thought it would do! - Edit PDF files easily - Recognize text and make them editable - Sign document simple as 1-2-3 It is not really cons, but some features are actually useless for me (ex: print to other companies to be sent at our offices)

Add a one-time use subscription Add a one-time use subscription. I feel this will be beneficial to a lot of your potential customers that do not run a business and may be using this software for personal use. I feel like a one-time 48hr subscription that can be purchased at a low cost would be profitable, especially if it can be repurchased at a later date if the user needs to use the program again. It does not make sense to offer a free 30 trial to users who are not going to use the program for more than 48 hours. I used this for free and you could have made money off of my usage by providing a one-time use subscription. Now, I have to make a new account with a different email if I would like to use your program again because I cannot afford to pay $100.00 for a subscription that I may only use once a year. So, just a suggestion.
