I've been using H&R Block tax preparation software (TaxCut before they changed the name) for at least 20 years. I have found it reliable, easy to use, and I have never been audited while using it. My only criticism is that sometimes it seems that they are slow in getting updates out after the initial release. I have a brother who uses a competitive company's product and his updates are sometimes a week to 10 days for H&R's. Other than that I'm very satisfied with H&R Block's software.
Pros: Easy to prepare, Easy to import documents, Fast
I am a retired CFO, and have been using this software for over 10 years to prepare and file personal returns for myself and others. The Deluxe version handles everything that I need very easily with its step by step question & answer format. I am able to automatically upload investment transactions from various institutions to avoid time consuming manual entry. Great product.
Pros: Easy to prepare, Maximizes refund, Easy to import documents
