I have been in the income tax preparation industry since 2003 and have used half a dozen of the top professional tax preparation products which have mostly been adequate but rather outdated. This software is very versatile and requires no desktop installation or setup. It also works across all of the computer platforms, from Windows to Mac, which is VERY helpful since not everyone loves Windows. The only qualm that I have with this product is its rapid development, which sometimes causes bugs. It is usually not a problem, as that development is mostly committed outside of the main tax season and any developmental problems are always rapidly addressed and resolved. Such is the nature of advanced software development, if you want the most cutting edge of features, there must be some sacrifices. I regularly test professional tax preparation softwares during my off season and I guarantee that there is simply NO SOFTWARE like this out there, period! MOST professional tax filing cloud solutions are barely usable, even from large brands and many lack even the most elemental of features. MTPO is PACKED with options which I have never before seen in such a software, and they keep on adding more options, which turn this complicated income tax preparation process into an automated breeze. Especially when it comes to remote preparation, signing and distribution of the taxpayer documents, they are second to none in my experience, which is quite extensive. The pricing is also VERY reasonable considering what you are getting. Under $1,000 per year, which includes Corporate (1120/1120S) and Partnership (1065) modules as well as ALL of the states, electronic signature, distance processing, document portal, multi user management, etc. In my book, this software deserves at least a 4.5 star rating, with half a point taken simply for its fast development cycles which sometimes trigger bugs, which are mostly cosmetic and easily resolvable without the assistance of staff. Such rapid implementation of features, while increasing the beta cycle of the software, also ensures its fast developmental advancement, which is what has created such a robust product in the first place. I encourage everyone looking for cutting edge, functional, robust and easy to learn professional tax software which is easy to setup and run, to give this one at least a try. This is NOT your usual clunky desktop software, convoluted and outdated, which is really mostly what is available at this point. After using this specific software since 2014, I am amazed that there is literally NOTHING out there that comes close to it, at any price. While it is NOT perfect, it is still the best there is. Yes, not one of the best, but the best. I would give a second best software I tested 3.5 stars, it is also cloud based and I won't mention the brand, but as you can see, they are not even close, despite a 3 fold price difference!
