TaxSlayer

TaxSlayer provides forms, calculations, and resources for preparing and electronically filing federal and state tax returns. Its listed capabilities include self-employment, investment, and rental income, plus audit support. Paid products support the IRS forms, credits, and deductions covered by the software, though business and other specialized situations may not be included. Simply Free is limited to eligible taxpayers, with eligibility based on age, income, credits, and deductions; it includes one federal return and one state return and costs nothing. Users can prepare and file federal and state taxes through the mobile app on a smartphone or tablet, as well as on the web. W-2 and 1099 import is listed, and support instructions describe uploading a PDF copy of a W-2. TaxSlayer lists AES-256 encryption for data in transit and at rest, multi-layer authentication, and a dedicated cybersecurity team. Phone and email support is offered year-round for all packages.
