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.

Federal T1 General

Provincial and territorial returns: all 13 jurisdictions

LinuxTax computes the provincial or territorial tax and applicable credits for every Canadian province and territory, in the same install, at the same price ($0).

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).

Slips

Federal slips

T4, T4A, T4E, T4RIF, T4RSP, T4FHSA, T4PS, T5, T5007, T5008, T3, T5013, RC62.

Quebec RL slips

RL-1 through RL-31 fully parsed; federal counterparts auto-derive RL boxes where applicable.

Slip entry

Type slips in directly, or import a downloaded CRA Auto-fill My Return archive from your own machine. We never sign in to CRA on your behalf; we never see your CRA credentials.
