TurboTax Deluxe Federal 2021 is Intuit's flagship desktop tax preparation software designed for individuals filing federal returns. It provides step-by-step guidance to help you accurately complete your federal tax return and maximize your eligible deductions and credits, covering over 350 common deductions.

The Deluxe edition is ideal for homeowners, mortgage holders, and those with charitable contributions, as it includes specialized guidance for deductions related to mortgage interest, property taxes, and donations. It supports manual entry of all federal forms including Schedule C and Schedule D, and allows up to five federal e-files so you can file returns for family members in the same household. State filing is sold separately and state e-file incurs an additional fee.

The software runs on Windows PC and requires an Intuit account for installation and activation. Your license code is tied to a single Intuit account but can be installed on up to five devices. It supports import of 1099 and other tax forms directly from many financial institutions, including major brokerages and banks.
