UpdatedOct 2026

If you are a US citizen or green card holder living in Canada, you file a US return every year on top of your Canadian one. These guides explain how each Canadian account, slip and benefit is treated on that return, in plain language, with the official sources linked.

Never filed before? Start with Catching up on missed years. Quick questions about Lou itself are in the FAQ.
