Most free online tax software companies are comparable in their offerings and requirements. Few of them offer only free filing, so you might not qualify for their free services. United Way’s MyFreeTaxes service lets anyone file online for free as long as you earned $73,000 or less (for tax year 2022), and you don’t have income from rental property or a farm. Cash App Taxes offers only free filing, so you can file through the app without worrying about being upsold.
