Filing

Which treaty countries do you cover?

France (1994), United Kingdom (2001), Germany (1989), Canada (1980), Australia (1982). Each has a dedicated treaty desk with article citations.

Updated August 2026

Each desk lists the articles relevant to expats (re-sourcing rules, pension provisions, savings-clause carve-outs) and how we cite them on Form 8833.

If you're in a country we don't list, the engine still produces the draft package it can support — you just won't get the treaty-position cites and may want a one-off review from a CPA familiar with that treaty.

The diagnostic, supported calculations, and in-wizard summary are free. Payment is required to generate the PDF package.
