What LinuxTax supports
Tax year 2026. This page is the canonical statement of supported platforms, forms, schedules and situations. If something is missing, it is listed under Limitations.
Platforms
Linux (native)
Native, and runs on all major distributions: Debian, Ubuntu, Linux Mint, Fedora, openSUSE, and Arch. No Electron, no embedded browser.
Windows
Windows 7, 8, 10 and 11. The Windows 7 build is not a separate “legacy edition”; it is the same release as Windows 11, and it will stay that way.
Offline
Everything below runs without an internet connection. The only outbound network call the application ever makes is the CRA NETFILE submission, and only when you press the button.

Quebec (TP-1.D-V): detail
Most desktop tax tools for Linux either skip Quebec or treat it as a paid‑tier feature. LinuxTax handles a TP-1.D-V return in the same install, in the same UI, at the same price ($0).
