There is no surprise in the fact that TaxSlayer provides a tax preparation program with which your 1040EZs can be put together in no time. What’s shocking, however, is that by opting for this product you’ll also be entitled to file one of your state refunds entirely for free. But this software isn’t the only thing that TaxSlayer users can enjoy without paying a dime – they just need to think outside the box. In fact, one of the extra services – which is included in the top-tier programs – can be tested for 30 days during which unsatisfied users can ask for a full refund.
