Tax software is computer software designed to assist individuals and businesses with the preparation and filing of tax returns.

Tax software can automate many of the calculations and data entry tasks involved in tax preparation, and can help ensure that tax returns are accurate and complete.

Depending on the software, users may be prompted to enter relevant financial information, such as income and deductions, and the software will calculate the appropriate taxes owed or refunds due.

Tax software may be available as downloadable programs or as cloud-based services, and may be designed for specific types of taxes or for general tax preparation. Some popular tax software programs include TurboTax, H&R Block, and TaxAct.
