Moving from Canada to Kansas: Taxes

Kansas runs a graduated income tax with three brackets topping out at 5.7%, which lands in the middle of the pack for US states but is nowhere close to any Canadian province’s top rate. The detail that actually matters for a lot of Canadians is where in Kansas they land. The Kansas City metro straddles the Kansas-Missouri line, and the Kansas-side suburbs, Overland Park, Olathe, Lenexa, charge no city earnings tax at all, while Kansas City, Missouri, just across the state line, adds a 1% earnings tax on top of its own state rate. For someone weighing an offer at Garmin or T-Mobile in Overland Park against one on the Missouri side, that’s a real number, not a rounding error. Wichita, on the other side of the state, has its own draw: an aerospace and aviation cluster anchored by Textron Aviation, Spirit AeroSystems, and the Learjet legacy, plus Koch Industries as the state’s largest private employer.

How does Kansas’s tax compare to provinces?

Kansas’s top bracket sits at 5.7%, well below every Canadian province’s top marginal rate, and the state has no local income tax layered on anywhere.

Jurisdiction	Top rate	Notes
Ontario	~20.5% (with surtax)	On income above $220,000
BC	20.5%	On income above $252,752
Alberta	15%	On income above $355,845
Quebec	25.75%	On income above $126,000
Kansas (state only)	5.7%	Top of three brackets, no city add-on anywhere

On $150,000 of employment income, Kansas state tax alone runs roughly $7,000 to $7,700, with no city tax to add regardless of whether that’s Overland Park or Wichita. Ontario provincial tax on the same income would run closer to $17,000 to $19,000 CAD. Kansas comes out well ahead of any province, and its lack of a local earnings tax also puts it ahead of its own metro neighbor across the state line.

How do the Kansas tax brackets work?

Kansas uses three graduated brackets: 3.1% on lower income, 5.25% on a middle band, and 5.7% on income above the top threshold, applied to taxable income after Kansas’s own deductions and exemptions.

Kansas starts its calculation from federal adjusted gross income, so anything the treaty already excluded at the federal level, most notably RRSP growth deferred under Article XVIII, never enters the Kansas base either. The state’s own standard deduction and personal exemptions apply on top, and there’s no separate city or county income tax anywhere in Kansas to stack on. That last point is the one that draws direct comparison to Missouri, where Kansas City and St. Louis both charge a 1% earnings tax. Live or work in the Kansas-side suburbs, Overland Park, Olathe, Lenexa, Shawnee, and you pay the state rate only. Cross the state line into Kansas City, Missouri, for the same job, and the 1% earnings tax applies on top of Missouri’s own state rate.

What about the Kansas City metro border specifically?

This is the detail most Canadians moving into the KC metro end up asking about directly, since it can shift a job-location decision by a real dollar amount.

Sprint’s old headquarters (now T-Mobile’s substantial Overland Park campus), Garmin, and a cluster of other employers sit on the Kansas side of the metro, in cities with no local income tax. Commute or relocate to a downtown Kansas City, Missouri, employer instead, and the 1% earnings tax applies to wages earned for work physically performed inside Kansas City limits, whether you live there or just work there. Kansas’s own state rate tops out somewhat higher than Missouri’s graduated rate, so the two paths aren’t wildly different in total burden, but the mechanics differ: Kansas has no local add-on to worry about tracking, while Missouri’s earnings tax depends on where the work is physically performed, which matters if a job involves hybrid or multi-location work across the state line.

How does Kansas treat the RRSP?

Kansas starts from federal adjusted gross income, so it inherits whatever the treaty already resolved federally. The RRSP treaty deferral under Article XVIII keeps the account’s growth out of federal AGI while it stays deferred, and Kansas follows along, taxing nothing until a distribution shows up in federal AGI. When distributions do occur, they flow through to the Kansas return at the applicable graduated bracket rate, same as any other income once it’s in the federal base.

Kansas also fully exempts Social Security benefits from state tax, a change effective with the 2024 tax year that removed the income threshold the state used to apply. Whether RRSP or RRIF distributions can be characterized to line up with any separate Kansas pension exclusion depends on the details of the plan and how it’s reported federally; that’s worth confirming before building a retirement drawdown plan around it.

TFSA income is taxable federally with no treaty shelter and flows straight through to the Kansas return at the applicable bracket. The standard advice to close the TFSA before you leave Canada still applies.

What happens on the Canadian side?

Leaving Canada for Kansas triggers the same departure sequence as any Canada-to-US move:

• Deemed disposition at fair market value on worldwide property
• A final Canadian return covering January 1 through the departure date
• Provincial tax at your home province’s rates for the period you were still resident
• T1161 and, where the deemed disposition gain crosses the threshold, T1243
• Notifying the CRA of your change to non-resident status
• RRSP stays open and deferred; TFSA gets closed before departure

On the US side, the arrival-year mechanics follow the usual pattern covered in the first US tax return guide, and Kansas’s part-year return picks up only the income earned after you became a resident.

What other taxes does Kansas have?

Kansas layers three other taxes worth knowing before you move, and the picture doesn’t match the low-ish income tax story.

• Sales tax: 6.5% at the state level, and it’s a genuine outlier, one of the higher statewide base rates in the country. Cities and counties add their own layers on top, pushing many combined rates past 8% and, in a fair number of areas, past 10%. Kansas also historically taxed groceries at the full combined rate longer than most states, though that’s been phasing down. Day-to-day spending in Kansas is not the bargain the income tax picture might suggest.
• Property tax: relatively high, with effective rates typically running 1.2% to 1.5% of market value, well above most Ontario municipalities’ 0.6% to 1.2% range and higher than Missouri’s roughly 0.9% to 1.0%.
• Estate and inheritance tax: Kansas has neither. For a Canadian settling in with a sizable estate, that’s one less planning layer compared to states like Illinois or Washington.

How does Kansas compare to nearby states?

Kansas sits inside a small cluster of Midwest and Mountain states most cross-border movers compare it against directly.

• Missouri: a lower graduated top rate, around 4.8%, but Kansas City, Missouri, and St. Louis both add a 1% city earnings tax. The Kansas-side KC suburbs avoid that entirely, which is the main reason so many cross-border movers into the metro end up comparing an Overland Park address against a Missouri-side one.
• Iowa: moved to a flat rate in recent years, generally landing below Kansas’s top bracket, with no local income tax layer either.
• Colorado: a flat rate as well, typically lower than Kansas’s top bracket, though Colorado’s cost of living and property values in the Denver metro run considerably higher.

Kansas sits in the middle of this group on income tax, ahead of Missouri’s KC and STL metros once the city tax is counted, but behind flat-rate neighbors like Iowa and Colorado on the state rate alone. Where Kansas pulls ahead is the total absence of any local income tax anywhere in the state, a genuine simplicity advantage over its own metro’s Missouri side.

What should I do next?

The Canadian exit is identical no matter which state you land in: work through the departure checklist before you go. On the Kansas side, the one decision that actually moves your number if you’re headed to the KC metro is which side of the state line you settle on, since that’s what determines whether a 1% city earnings tax applies. Outside the metro, in Wichita or elsewhere in the state, it’s simply the graduated state rate with no local add-on.
