H&R BLOCK Basic 2026 Tax Software for Windows and Mac

Prepare and work through 2026 tax-return preparation tasks on a Windows PC or Mac with H&R Block Basic tax software. The Basic edition provides a named entry point in the H&R Block consumer tax software range for users who want software-based tax preparation. Its Windows and Mac designation matters where a household uses more than one desktop operating system or where the installation platform has already been selected. H&R BLOCK 1013800-26LEN is supplied as Lenovo electronic software delivery, placing the product in an ESD format rather than a boxed-disc format. This ordering code is useful when the required product is specifically the 2026 Basic edition for Windows and Mac and electronic fulfillment is the selected delivery method. Keep the product edition, tax year, operating-system designation, and delivery format aligned when selecting software for a tax-preparation workstation. Within the H&R Block tax software range, this item is distinguished by its Basic edition designation, 2026 tax-year designation, Windows and Mac compatibility, and Lenovo ESD format. Those characteristics identify the software type and delivery channel without implying tax-form coverage, filing services, license quantity, or minimum system requirements. It fits users seeking the Basic software edition rather than a physical-media package.
