All software listed makes similar promises when it comes to accuracy and refunds, but it’s important to check the fine print to ensure that none of your personal details will end up triggering an unexpected charge. For example, some services only offer free tax services for people whose income falls below a set limit. Others only offer one free year of filing, so you’ll have to pay more or switch to another service if you used it last year. Keep an eye on any extra fees for state tax returns as well. Many services also charge extra for more advanced tax services. H&R Block boasts that its free version accepts more complicated income sources, including unemployment income Form 1099-G, than competitors like TurboTax. This service connects you with tax filing software, simplifying the process of seeking out a deal. Both options provide an easy way to file for free. However, the TaxSlayer SimplyFree Edition is worth a mention if you’re expecting a simple situation. This service also offers special filing perks to military service members.
