Moving from Toronto to Chicago: Taxes, RRSP, and the Finance Corridor

Toronto and Chicago sit on a clean comparison, because Illinois runs a flat 4.95% state rate with no brackets to model, and Chicago layers on no city income tax at all. That makes this corridor unusually simple to price out next to New York, where a second city tax stacks on top of the state one. The traffic is real: Bay Street finance talent moves into LaSalle Street and the commodity trading world around CME Group, consulting firms rotate people through their Chicago offices, and a growing West Loop tech scene is pulling in engineers too. The departure-year bill and the RRSP mechanics still need to be worked through before the lower ongoing rate is actually yours.

Why does Toronto’s tax rate drop so much in Chicago?

Because Illinois runs one flat rate instead of Ontario’s graduated brackets and surtax stack, and Chicago adds nothing on top of it. Ontario’s five brackets top out at 13.16%, and the surtax adds 20% on basic tax above about $4,991 and another 36% above about $6,387, pushing the combined federal-plus-provincial top rate to roughly 53.53%. Illinois’ flat 4.95% plus federal brackets lands closer to 42% at the same income, with no city layer, no separate estate tax below $4 million, and a combined sales tax around 10.25% against Ontario’s 13% HST.

What happens to the deemed disposition on departure?

Ceasing Ontario residence triggers the departure tax at Ontario’s full surtax-augmented rates before any Illinois rule applies. Canada deems most property sold at fair market value on your departure date, half of the resulting gain becomes taxable, and the gain lands on your final Ontario return at Ontario’s rates.

• Illinois has no return to offset that bill against for the pre-move period; the departure tax is settled entirely on the Canadian side.
• The departure tax pillar covers the T1161 and T1243 mechanics, and the leaving-Canada checklist covers the full sequence.

Does Chicago charge any city income tax at all?

No. Illinois law gives no home-rule city, including Chicago, the power to levy its own personal income tax, which is a real difference from New York City’s separate 3.876% city tax on top of the state rate.

• Chicago funds itself through property tax, sales tax, and a set of business-facing levies (the lease tax, the amusement tax) instead of a payroll or income tax.
• A move to Chicago means checking one rate, the flat 4.95%, rather than stacking a state number and a city number the way a move to New York requires.

What happens to RRSP and TFSA taxes in Illinois?

The RRSP side is genuinely favorable here. The treaty defers US federal tax on RRSP growth automatically, Illinois starts from federal adjusted gross income with no state-level addback, and Illinois’ retirement income subtraction has historically treated RRSP distributions reported on the federal return as exempt from the flat state tax.

• That subtraction is the detail worth flagging to a CPA before drawdown, because it can zero out the Illinois tax on RRSP or RRIF income entirely, an outcome states like California don’t offer.
• TFSA income doesn’t get the same treatment; it’s taxed as investment income federally and flows through to Illinois at the flat rate. The RRSP and TFSA guide covers the case for closing the TFSA before departure.

What happens to OHIP and the health premium?

Both end, on different clocks, and Illinois replaces neither directly. OHIP coverage runs about three more months after Ontario residency ends, leaving a gap to plan for before US coverage starts.

• The Ontario Health Premium, up to $900 a year built into the Ontario tax bill, stops accruing the year after departure, and the Ontario Trillium Benefit stops the month after residency ends.
• Moving from Canada is a Special Enrollment Period event on the federal marketplace, giving 60 days to enroll in an employer plan or healthcare.gov coverage. The provincial health insurance guide covers the OHIP wind-down in full.

How does Chicago property tax compare to Toronto?

It runs meaningfully higher, and Cook County’s assessment system is part of why. Effective rates in Chicago typically land between 1.8% and 2.2% of market value once the county’s assessment ratio and equalization factor are applied, well above Toronto’s roughly 0.6% to 1%.

• The math is genuinely confusing on the Cook County side, since assessed value, the state equalization multiplier, and exemptions all move independently; a first-year buyer should budget on the actual tax bill of a comparable property, not a quoted mill rate.
• Ontario’s land transfer tax, doubled in effect by Toronto’s own municipal top-up, disappears on the buy side. Chicago’s own real property transfer tax (city, county, and state combined) runs closer to 0.9% to 1% of price, a fraction of what a comparable Toronto purchase carries.

Why are so many Toronto professionals moving to Chicago?

Three corridors feed this move, and they run on different reasons. Finance talent moves from Bay Street into LaSalle Street and the commodity trading world built around CME Group, along with asset management and insurance names like Allstate and Zurich.

• Consulting is the second corridor: McKinsey, BCG, and Bain all run major Chicago offices and rotate Toronto-trained consultants through them regularly.
• Tech is the newer one, centered on the West Loop and Fulton Market, with a Google office, the Salesforce Tower, and a growing base of startups drawing engineers who’d otherwise have stayed in the GTA.

Where do Toronto movers actually settle in Chicago?

It splits cleanly by life stage and commute preference. Finance and consulting movers without kids tend to land in the Loop or River North for walkability and proximity to the office towers, while tech hires cluster closer to the West Loop and Fulton Market itself.

• Families more often choose Lincoln Park or Lakeview for schools and housing stock, or push out to Evanston or Oak Park for a quieter, more suburban feel without losing the train commute downtown.
• None of it changes the tax analysis. Illinois’ flat rate and Chicago’s lack of a city income tax apply the same way regardless of neighborhood.

Should I sell the Toronto home before or after I leave?

Before, in most cases, if keeping the ordinary resident-sale rules matters more than the alternative. Selling while still an Ontario resident keeps the sale inside the principal residence exemption and avoids the section 116 clearance certificate process that applies to a non-resident vendor.

• Selling after residence ends keeps the home outside the deemed-disposition rules, since Canadian real property is already carved out of that, but it brings a shrinking exemption fraction and the certificate process instead.
• Ontario’s doubled land transfer tax only matters again if there’s a real chance of buying back into the Toronto market later.

What should I do before the move?

Pin the departure date on the facts first, since it fixes the surtax exposure on your final Ontario return and starts both the OHIP and Trillium clocks. Confirm which Chicago neighborhood or suburb your target home sits in before comparing property tax figures, since Cook County’s assessment ratio doesn’t behave like a simple percentage of price.
