RRSP Withholding Tax for US Residents, Explained

Short answer: if you're a US resident and you collapse your RRSP in one lump sum, Canada withholds 25% at the source. If you convert it to a RRIF first and take periodic payments instead, the rate drops to 15%. The difference on a $200,000 RRSP is $20,000 — which makes this one of the more expensive mistakes a cross-border retiree can make without even realizing there was a choice.

The basic rule

An RRSP (Registered Retirement Savings Plan) is a Canadian tax-deferred account — you didn't pay tax on the contributions or the growth while you lived in Canada, so Canada wants its share when the money finally comes out. If you're a non-resident when you withdraw, Canada collects that share as a withholding tax, deducted before the money ever reaches you.

The rate isn't set by ordinary Canadian tax law — it's set by Article XVIII(2) of the Canada-US Tax Treaty, and it depends entirely on how you take the money out:

Lump-sum RRSP collapse — 25% withholding. Cash out the whole account, or any portion of it as a one-time payment, and Canada withholds a quarter of it immediately.
RRIF periodic payments — 15% treaty rate. Convert the RRSP to a RRIF (Registered Retirement Income Fund) and take payments that qualify as "periodic" under the treaty, and the rate drops to 15% on the entire amount — not just the CRA-mandated minimum withdrawal.
Still a Canadian resident when you withdraw — no non-resident withholding. If you haven't yet become a US tax resident, ordinary Canadian resident withdrawal rules apply instead.

Why does the rate change based on how you take the money?

The treaty treats a steady, pension-like income stream more favourably than a one-time cash-out. A RRIF paying you a defined amount every year looks, to both tax authorities, a lot like a pension — and pensions get preferential treatment under the treaty. A lump sum looks like exactly what it is: someone converting a tax-deferred account into cash all at once. Canada taxes the second scenario more aggressively because it has less confidence about ever collecting anything from you again once the account is empty and you're living outside the country.

Worked example

A $200,000 RRSP, two different ways to take it out.

Option A — Collapse it as a lump sum: Canada withholds 25% = $50,000. You receive $150,000.

Option B — Convert to a RRIF first, take periodic payments: Canada withholds 15% = $30,000. You receive $170,000 — an extra $20,000 in your pocket, before you've even gotten to what happens on the US side.

What happens on the US side

The IRS recognizes an RRSP as tax-deferred under the Canada-US treaty, so you're not double-taxed on the contributions — but the withdrawal itself is still reportable US income, and the US will tax it at your ordinary income rate. The Canadian withholding tax you already paid generally becomes a Foreign Tax Credit (claimed on Form 1116) against that US tax bill.

That credit is where a lot of people assume the story ends — "I already paid Canada, so it's a wash." It isn't automatically a wash. If your US marginal rate on that income is higher than the 15% or 25% Canada withheld, you'll owe the US the difference. The credit prevents double taxation; it doesn't guarantee your total tax bill is capped at whichever rate Canada charged.

How to actually get the 15% rate

You don't get to just claim the 15% rate by asking for it — the payment has to genuinely qualify as "periodic" under the treaty and CRA administrative guidance. In practice, that means:

Convert the RRSP to a RRIF before you start withdrawing (an RRSP itself generally can't pay "periodic" amounts in the treaty sense — the conversion is what unlocks the lower rate).
Take payments that are level or a scheduled series over time — not one-time, irregular cash-outs.
Withdrawals up to twice the CRA-mandated minimum RRIF payment in a year generally still qualify as periodic; withdrawing well beyond that in a single year risks the excess being treated as a lump sum for withholding purposes.

The financial institution holding the RRIF applies the withholding rate at the time of payment, so this is worth confirming directly with them before you take the first withdrawal — not after.

Common mistakes

⚠️Collapsing the RRSP right after becoming a non-resident

A lot of people close out old Canadian accounts as one of the first things they do after moving — before realizing that's exactly the move that locks in the higher 25% rate. Converting to a RRIF first, even if you plan to draw it down quickly, is almost always cheaper.

ℹ️Assuming the Foreign Tax Credit makes it a wash

The credit avoids double taxation, not a higher total bill. If your US bracket is above the Canadian withholding rate, budget for a top-up when you file your US return.

📋Not confirming "periodic" status with the institution first

The 15% rate isn't automatic just because you technically have a RRIF — confirm your withdrawal schedule qualifies before you take the money, since the withholding is applied at source and is awkward to correct after the fact.
