FreeTaxUSA is a mostly free online tax software option. Your federal returns are free (no matter how complicated your tax situation is), but you’ll need to pay to file state tax returns. It offers options for importing previous tax returns and filing an amended tax return. The Deluxe version includes priority live chat, customer support and access to its tax specialists and audit service. These tax professionals should be able to address all your specific income tax return questions — from what paperwork you need to how to understand an audit notice and write a response to the IRS.
