I have used H&R Block Premium for years and it has saved me hundreds of dollars each year that I would have paid to an accountant. Besides needing to file as a married couple, I also own a duplex, and have a registered small business. All of those items together would make things quite confusing were I to try to do it myself. With H&R block, it walks you through the process asking you specific questions along the way, as well as providing helpful tips or information on some issues. Although I have rarely had to used it, they also have a support line included with the products, so if you are unsure about something and need more information, they are just a phone call away to help through the process.
Pros: Easy to prepare, Maximizes refund, Easy to import documents
