The RRSP is Canada's most valuable retirement savings vehicle — but for Americans living in Canada, Canadians moving to the US, and dual citizens, the RRSP creates significant US tax complexity. The Canada-US DTA provides a deferral mechanism, but it requires an active election. Failure to elect means paying US tax on RRSP growth every year — a common and costly mistake for cross-border individuals who don't know about the Form 8833 requirement.
If you are moving from Canada to the United States with an existing RRSP, follow this sequence:

Transfer CAD↔USD at the Real Exchange Rate →Without a timely Form 8833 election, the IRS treats RRSP income (growth) as currently taxable in the US each year. If you have been a US resident for several years without making the election, you may have unreported RRSP income on past US returns. Options: (1) File amended returns (Form 1040-X) for open years (generally the last 3 years) to include the treaty election on Form 8833 for each year. This 'backdates' the election retroactively. Because the RRSP income was not previously reported, the amended returns would typically show zero additional tax (the treaty election means no tax is due) — but you are making the disclosure. (2) If income was already reported on previous returns: amended returns to claim the treaty deferral may generate a refund of taxes paid on RRSP growth. (3) If using Streamlined Compliance Procedures: include Form 8833 with the amended returns. Practical experience: the IRS generally accepts late Form 8833 elections through amended returns without penalty, particularly when the taxpayer can show the failure was an oversight and no US tax was evaded (since treaty deferral eliminates the tax). Document the election carefully and retain permanently.
No — RRSP contributions are not deductible for US federal income tax purposes. The US tax code provides deductions only for contributions to US-qualified retirement plans (401(k), IRA, SEP-IRA, etc.). The Canada-US DTA Article XVIII(7) provides deferral of RRSP income but does NOT extend deductibility of RRSP contributions. Result: a US citizen in Canada contributes $30,000 to an RRSP: Canadian deduction — yes, saves ~$12,000–$15,000 in Canadian tax. US deduction — no. The $30,000 is made with after-US-tax dollars and becomes US basis in the RRSP. On withdrawal: Canadian RRSP tax applies at marginal rate; US taxes the amount above the US basis. If the Canadian rate is higher than the US rate: the Foreign Tax Credit should offset US tax. The RRSP is still worth using for US citizens in Canada primarily for the Canadian tax benefit — the US basis tracking is an administrative burden but not a disaster.
Generally no — unless you have specific advice from a cross-border CPA on your situation. The TFSA's tax benefits in Canada (tax-free growth and withdrawal) are not recognised by the US. For a US citizen using a TFSA: (1) TFSA growth is fully taxable in the US each year as ordinary income — the 'tax-free' Canadian benefit is fully offset by US taxation. (2) If the TFSA is a foreign trust: Form 3520 required annually — $10,000 penalty for failure. (3) PFIC issues if Canadian funds are held. (4) FBAR and Form 8938 reporting required. Alternatives: US citizens in Canada should instead maximise their US Individual Retirement Account (IRA or Roth IRA) — these are US-recognised retirement plans. Roth IRA: $7,000/year limit; no deduction, but tax-free growth and withdrawals. Canada's treatment of Roth IRA: not tax-deferred in Canada (Canada does not recognise Roth IRAs as pension plans); growth is taxable in Canada annually. There is no perfect answer — a cross-border CPA can help optimise between Canadian and US registered account usage.
RRIF mandatory annual withdrawals are taxed as follows: Canada: RRIF withdrawals are ordinary income in Canada; Canadian withholding applies (25% for lump sum, 15% for periodic under DTA). US (with treaty election in place): the RRIF withdrawal is taxable as ordinary income in the US. Calculation: US-taxable amount = gross RRIF withdrawal − pro-rata share of accumulated US basis. US basis is the total of non-deductible contributions made to the RRSP while a US resident (each year tracked). If you never contributed while a US resident: zero basis — full withdrawal is US-taxable. Foreign Tax Credit: Canadian withholding tax on the RRIF withdrawal is creditable dollar-for-dollar against your US income tax liability on the same income (Form 1116). In most cases where Canadian rates exceed US rates: the FTC eliminates US income tax on RRIF withdrawals, and no double taxation occurs. State income tax: some US states do not recognise the Canada-US DTA and may tax RRIF withdrawals without allowing an FTC. Check your state — this is particularly relevant in California.
