Ottawa doesn’t send Columbus the volume that Toronto does, but the corridor is a tighter fit than the numbers suggest. CSE and Shared Services Canada cybersecurity staff move into JPMorgan Chase’s massive Columbus technology and security operation, one of the bank’s largest sites in the country. DND procurement and logistics people land at Battelle Memorial Institute, a federally funded research and development center much like SEI in Pittsburgh, just built around defense and applied science instead of software. NRC researchers move into Ohio State’s Wexner Medical Center research arm and into Battelle’s broader science base. Telecom engineers from Nokia and Ciena’s Ottawa operations feed the same tech sector pulling in Amazon and Meta’s data center build-out, and Big Four government-consulting alumni land at JPMorgan Chase, Nationwide, and Huntington Bancshares, all headquartered or heavily staffed in Columbus. The tax gap is enormous, but it’s a two-authority exit on the way out, not a three-jurisdiction one.

✓Key takeaway

Ontario’s combined federal-plus-provincial top rate runs about 53.53%, built from a 13.16% top provincial bracket plus a 20% surtax above roughly $4,991 of basic Ontario tax and a further 36% above roughly $6,387. Ohio’s state income tax now tops out around 3.5% on income above roughly $115,000, and Columbus adds a 2.5% municipal income tax on top, for a combined state-plus-city rate around 6%. The departure runs through exactly two authorities, the CRA and Ontario, settled on one final T1; there’s no separate provincial exit filing to coordinate.

How much does Ottawa’s tax rate drop in Columbus?

By a wide margin, even with Columbus’s city tax added on top. Ontario’s surtax stack pushes the combined federal-plus-provincial top rate to roughly 53.53%, built from graduated provincial brackets topping out at 13.16% plus two layers of surtax.

Ohio’s state rate tops out around 3.5% above roughly $115,000 of taxable income, with lower graduated rates below that, and Columbus’s 2.5% city tax applies on top. Combined state-plus-city lands around 6% at the top, a fraction of Ontario’s provincial layer alone, before either country’s federal tax enters the picture.

Does Columbus charge its own city income tax?

Yes, and at 2.5% it sits among the higher municipal rates in Ohio, applying to essentially all earned income whether you live in the city or just work there. Columbus taxes wages, salaries, and most self-employment income at 2.5%, on top of Ohio’s state rate.

Settle in a suburb like Dublin, Westerville, or Bexley instead, and that suburb’s own municipal rate applies, most sitting close to Columbus’s 2.5% since Franklin County municipalities cluster tightly. Reciprocity credits exist between most central Ohio municipalities, so double taxation on the same wages is rare, but the city tax itself is not optional anywhere in the metro.

What happens to the departure tax when you leave Ontario?

It applies in full, at Ontario’s surtax-augmented rates, and it’s settled through exactly two authorities: the CRA and Ontario, both handled on your final T1. Canada deems most property sold at fair market value on the date Ontario residency ends, and half of any resulting gain becomes taxable.

That gain lands on the final Ontario return at Ontario’s rates, surtax included, before Ohio has any bearing on the calculation. Ohio has no comparable exit tax and no return to offset the bill against for the pre-move period. The departure tax pillar covers the T1161 and T1243 mechanics in full.

How do Ontario and Ohio compare, line by line?

The two systems differ on structure as much as headline rate, and Columbus’s city layer is the detail most flat comparisons leave out.

Category	Ottawa/Ontario	Columbus/Ohio
Provincial/state income tax	5.05% to 13.16%, graduated, plus surtax	Graduated, tops out ~3.5% above ~$115,000
City income tax	None	2.5% (Columbus, most earned income)
Combined top marginal rate	~53.53%	~40-43% (Columbus, top federal bracket)
Sales tax	13% HST	~7.5% combined (state + Franklin County)
Property tax	~1.0% to 1.3% of assessed value	~1.5% to 2.0% effective (Franklin County)
Estate tax	None (deemed disposition on death instead)	None; repealed in 2013
Departure filing	Two authorities: CRA + Ontario, one T1	No comparable exit filing

What happens to RRSP and TFSA taxes in Ohio?

The RRSP side carries over cleanly here, which is one less thing to plan around in this corridor. The treaty defers US federal tax on RRSP growth automatically, and Ohio starts its own tax calculation from federal adjusted gross income, so the deferral holds at the state level with no separate addback or election required.

On withdrawal, the distribution flows into federal AGI, then into Ohio taxable income at Ohio’s graduated rates, plus Columbus’s 2.5% city tax if the recipient still lives there. TFSA income gets no equivalent shelter; it’s taxed as ordinary investment income and flows through the same way. The RRSP and TFSA guide covers the case for closing the TFSA before departure.

Does Ohio have an estate tax?

No. Ohio repealed its estate tax in 2013, and it has no separate inheritance tax either, unlike Pennsylvania one state over.

That leaves Ontario’s deemed-disposition-at-death rule as the only real “estate tax” event either country applies to this corridor, and it’s triggered on the Canadian side regardless of where the person eventually settles or dies. Ohio simply doesn’t add a second layer on top.

What happens to OHIP and the health premium?

Both end, on different clocks, and Ohio replaces neither directly. OHIP coverage runs about three more months after Ontario residency ends, leaving a gap most movers plan an employer plan or marketplace coverage around.

The Ontario Health Premium, up to $900 a year built into the Ontario tax bill, stops accruing the year after departure, and the 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, and this corridor’s larger employers, JPMorgan Chase, Nationwide, and Battelle among them, run group plans that typically start before the OHIP tail runs out. The provincial health insurance guide covers the wind-down in full.

Where do Ottawa’s government workers land in Columbus?

Mostly across a finance, security, and applied-research corridor with a real federal-government echo to it. CSE and Shared Services Canada cybersecurity staff move into JPMorgan Chase’s Columbus technology and security operation, one of the bank’s largest sites anywhere, and into names like CoverMyMeds and Root Insurance building out Columbus’s own tech scene.

DND procurement and defense-logistics staff land at Battelle Memorial Institute, a federally funded research and development center that runs on the same government-contract fluency a DND career builds. NRC researchers move into Ohio State’s Wexner Medical Center research arm and Battelle’s broader science base. Telecom engineers from Nokia and Ciena’s Ottawa operations feed the tech sector growing around Amazon and Meta’s data center investment, and Big Four government-consulting alumni move into JPMorgan Chase, Nationwide, and Huntington Bancshares for corporate finance and consulting roles. Cardinal Health’s headquarters rounds out the healthcare-logistics side for anyone coming from a supply-chain or procurement background.

Hypothetical example

Invented numbers. A CSE cybersecurity analyst leaves Ottawa for a security engineering role at JPMorgan Chase’s Columbus site, salary $145,000 USD, moving mid-year and buying a home in Dublin. Her final Ontario return covers January through her departure date, and deemed disposition applies to $22,000 CAD of unrealized gains in a non-registered account, adding roughly $11,000 of taxable capital gain that pushes her basic Ontario tax past the first surtax threshold that year. The exit runs through exactly two authorities, the CRA and Ontario, on that one final T1. Her $70,000 RRSP stays deferred under the treaty since Ohio starts from federal AGI, so nothing changes there until withdrawal. Going forward, her Columbus-area paycheck faces Ohio’s graduated state rate, well under 3.5% at her income level, plus JPMorgan’s Columbus office carrying the 2.5% city tax, for a combined state-and-city bite far below Ontario’s provincial rate alone. OHIP lapses three months after departure and she enrolls through JPMorgan’s group plan inside the 60-day marketplace window, and her Dublin property tax runs close to 1.9% of assessed value, noticeably higher than the roughly 1.1% she paid in Ottawa even on a lower purchase price.

Illustrative numbers only, not a real client and not advice for your facts.

What should I do next?

Start with the departure date, since it fixes the surtax exposure on your final Ontario return and starts both the OHIP and Trillium clocks. Then confirm the exact Columbus-area address, since the municipal rate varies by suburb even though the gap between them is small.
