Cross-Border Retirement for Business Owners: The Individual Pension Plan, the RRSP, the Cash Balance Plan, and the Owner Who Moves

October 1, 2026

A business owner who moves between Canada and the United States takes retirement savings built under one country's rules into the other's: a Canadian owner's individual pension plan and RRSP, a U.S. owner's 401(k) and cash balance plan. The treaty recognizes most of them and defers the tax, but contributions after the move, the plan's administration across the border, and the withdrawals each need planning. Here is each plan's treatment in the other country.

Moving a 401(k) or IRA Into an RRSP: The Paragraph 60(j) Rollover, the US Withholding That Leaks, and When It Is Worth It

September 18, 2026

Canada lets a returning or arriving resident move a US retirement plan into an RRSP without using contribution room, through a deduction under paragraph 60(j) that offsets the income inclusion. The catch is on the US side: the distribution is taxed and withheld by the US, the withheld amount never reaches the RRSP unless replaced from other funds, and the US tax often cannot be credited because the Canadian deduction leaves nothing to credit against. Here is the mechanism, the leak, and the cases where the transfer still wins.

Part XIII Withholding After You Leave Canada: The 25% Default, the Payments It Hits, and the Treaty Rates That Replace It

September 18, 2026

The day you become a non-resident of Canada, your Canadian income stops being taxed by return and starts being taxed at source: Part XIII of the Income Tax Act imposes a flat 25% on dividends, interest, rent, pensions, RRSP and RRIF payments, and other passive income paid to non-residents — collected by the payer, final in most cases, and reduced by the treaty only when the payer knows to apply it. Here is the regime, payment by payment, and the declarations and elections that manage it.

Returning to Canada After Years in the US: The Re-Entry Checklist for Your IRA, US Home, State Residency, and Arrival Basis

September 18, 2026

The returning Canadian is a newcomer with a history: US retirement accounts, perhaps a US home, a state to leave, an old departure-tax file to reopen, and RRSP room that survived the absence. The re-entry runs the newcomer rules in one direction and the departure rules in reverse. Here is the checklist, ordered by what has to happen before the border and what can wait for the first return.

RRSP and 401(k) Compared: Contribution Rules, Treaty Treatment, and What Each Becomes When You Cross the Border

September 18, 2026

The RRSP and the 401(k) are cousins — tax-deferred retirement accounts funded from earned income — and the cross-border mover treats them as interchangeable at their peril. Contribution mechanics, employer involvement, withdrawal rules, and the treaty's treatment of each in the other country differ in ways that decide whether to keep, collapse, or transfer. Here is the side-by-side, and what each account turns into after a move.

The RDSP After a Move to the US: Grants Stop, the IRS Sees a Trust, and Whether to Keep It Open

September 18, 2026

The Registered Disability Savings Plan is Canada's most generous savings vehicle — government grants and bonds that can exceed the holder's own contributions — and it depends on Canadian residency in ways the RRSP and TFSA do not: grants and bonds stop when the beneficiary becomes a non-resident, contributions are barred, and the US sees an account it has no treaty provision for. Here is what happens to an RDSP when the family moves, and how to decide whether it stays open.

The Section 217 Election on RRSP and Pension Withdrawals: When Filing a Canadian Return Beats Accepting the 25%

September 18, 2026

A non-resident's Canadian pension, RRSP, and RRIF payments are taxed by flat withholding — 25%, or 15% for periodic payments under the treaty — with no return required. Section 217 lets the non-resident file a Canadian return instead and pay graduated rates, which can cut the tax sharply for retirees with modest world income. Here is how the election works, the world-income catch, the NR5 that reduces withholding in advance, and who should use it.

Wash Sales and Superficial Losses: Two Loss-Denial Rules With Different Windows, and the Trade That Trips Both

September 18, 2026

Both countries deny a capital loss when you sell and buy back too soon — the US wash sale rule and Canada's superficial loss rule — but the rules differ in scope (securities versus identical property), in who counts (a spouse and controlled corporation in the US; an expanded affiliated-person list including your own RRSP and TFSA in Canada), in what happens to the denied loss, and in whether crypto is covered. A cross-border investor harvesting losses runs both tests on every trade. Here is the side-by-side.

Form 8891 Is Gone: How RRSP Treaty Deferral Works Now, and the One Case Where a Late Election Still Needs Paper

September 17, 2026

Until 2014, Americans with RRSPs filed Form 8891 every year to elect treaty deferral on the plan's growth — and those who missed it faced retroactive taxation. The IRS eliminated the form and made the deferral automatic for eligible individuals. Here is how the deferral works now, who is covered automatically, who isn't, and what an RRSP still requires on the US return.

Form 8938 and the FBAR Side by Side: Thresholds, What Each Counts, and Why Most Americans in Canada File Both

September 17, 2026

Two forms report the same Canadian accounts to two different agencies under two different rulebooks — the FBAR to FinCEN at US$10,000, Form 8938 to the IRS at US$200,000 for a single filer abroad. Filing one does not satisfy the other, and the asset definitions diverge in ways that catch RRSP holders, fund investors, and people with signature authority. Here is the side-by-side, and the annual routine that files both correctly.

Registered Accounts Inside a Streamlined Submission: How the RRSP, TFSA, and RESP Each Land on the Three Catch-Up Returns

September 17, 2026

A Canadian's streamlined submission is mostly about registered accounts, and each one is treated differently: the RRSP defers under the treaty with no form now required, the TFSA is a taxable account with a possible trust-reporting question, and the RESP is a taxable account the IRS may see as a trust — with grants and growth taxed to the subscriber. Here is how each account appears on the returns, the FBARs, and the certification.

Cross-Border REIT Investing: US REITs in Canadian Hands, Canadian REITs in American Hands, and the Account-Location Rules That Decide the Yield

September 15, 2026

Real estate exposure through REITs swaps property-level tax problems for securities-level ones: US REIT distributions carry their own withholding quirks (return of capital, capital gain distributions, and rates that differ from ordinary dividends), Canadian REITs are presumptively PFICs for US persons, and the RRSP/TFSA/taxable location decision moves after-tax yield by whole percentage points. Here is the map.

What Happens to My 401(k) When I Move to Canada? Leave It, Roll It, or Move It — the Three Options Priced

September 14, 2026

A 401(k) survives the move to Canada intact: the treaty defers Canadian tax on its growth, and distributions are taxed where you live when you take them. The real questions are whether to roll it to an IRA, whether an RRSP transfer ever makes sense, and how withdrawals will be taxed on both sides in retirement. Here are the three options with the tax mechanics of each.

Do I Pay Departure Tax When I Leave Canada? What Triggers It, What Escapes It, and What the Bill Actually Looks Like

September 14, 2026

Canada's departure tax is a deemed sale: leave, and most of your property is treated as sold at fair market value the day you go, with the accrued gains taxed on your final return. But the biggest asset classes — your home, your RRSP, your pension — are exempt, so many movers owe far less than they fear. Here is what is in, what is out, and how the bill is computed.

Divorce Across the Border: Support Payments, Property Splits, and Retirement Accounts When the Ex-Spouses File in Different Countries

September 14, 2026

A cross-border divorce runs one settlement through two tax systems that disagree about almost everything: Canada deducts spousal support the US no longer does, the treaty referees payments that cross, property transfers roll over differently, and dividing an RRSP or a 401(k) each has its own machinery. Here is the map for separating couples with a border between them.

The Year You Move From Canada to the US: Who Taxes What, Month by Month

September 14, 2026

The move year is two tax lives stitched at the departure date: Canada takes world income before and Canadian-source income after; the US takes what its residency start captures, shaped by the dual-status-or-election choice. Getting each income item into the right country's column — salary, bonus, RRSP, dividends, gains — is the whole art of the transition year. Here is the map.

What Happens to My RRSP When I Move to the US? Keep It Growing, or Collapse It at 25% — the Real Comparison

September 14, 2026

The RRSP survives a move to the US better than any other Canadian account: no departure tax, continued deferral in both countries, and a choice worth real money — leave it growing, convert to a RRIF for 15% treaty withholding on periodic payments, or collapse it at 25%. Here is how each path is taxed and how the US measures its share.
