I have been using Tax Slayer for probably 10 years. Even though we were military and had the option to do our taxes for free, we often opted for a paid version. I can now, just this year, only access my last 4 years of returns, even though I have had the same account for YEARS. Why? I paid for them. I USED to be able to access all of them. This year, I found their program to be lacking and it overlooked several errors that Turbo Tax found when I input the same information with them. Not only did the other program find my errors, their program was comprehensive and explained things where TaxSlayer was content to let the mistakes ride, with no explanation. There are so many changes this year with child tax credits and whatnot, and Tax Slayer was a big let down when going through the 'guided' version! Not Happy, I do NOT recommend them anymore! I will be moving whatever returns I still have access to, to another platform.
