I forgot the Roth IRA treaty election on my first Canadian return — is it too late?
Not necessarily. The election is supposed to be made on your first Canadian return after becoming resident, and there is no automatic right to file it late. But in practice CRA has discretion to accept late elections, and practitioners report success with well-documented requests. If CRA refuses, the treaty competent-authority process is the backstop.
The deadline rule
| Item | Detail |
|---|---|
| When | First Canadian tax return after establishing residency |
| Late filing | No statutory right — but CRA may accept on a discretionary basis |
| What to file | A letter to your tax centre explaining the oversight, identifying the Roth, and requesting the election be accepted late |
How to ask for late relief
- Write to your CRA tax centre (keep it factual: move date, first return year, why it was missed).
- Attach evidence you otherwise complied (returns filed, no contributions since becoming resident — this matters enormously).
- Do not contribute in the meantime.
A clean record — election missed but no contributions made — is the fact pattern most likely to succeed.
If CRA says no
The US-Canada treaty has a competent-authority (mutual agreement) procedure. You or your advisor can ask the two tax authorities to resolve the double taxation. It's slow, but it exists precisely for situations like this.
Frequently asked questions
I missed it five years ago and contributed twice since. Any hope?
Harder — the contributions are the bigger problem (they may have destroyed the treatment regardless of the election). Get professional advice before doing anything else.
Can my accountant just amend the first return?
Amending to add the election is exactly what the late-relief request does — but it needs CRA's acceptance, not just a refile.
Does the US offer any parallel relief?
The election is a Canadian concept; the US side doesn't need it. Your US Roth treatment is unaffected.
