$115K Salary in Kansas City vs. Austin: Missouri's Income Tax Vote and the Total Tax Burden Math in 2026

You're earning $115,000 in Kansas City, Missouri, and you've got a standing offer to move to Austin, Texas at the same salary. Texas has no state income tax — that's the pitch — and it sounds like an automatic win. But Missouri lawmakers just passed legislation that sends a major tax restructuring proposal to voters: eliminate the state income tax entirely and replace it with higher sales taxes. Does that change your calculus? And even before that vote happens, is Austin actually cheaper when you stack up the full tax and housing picture?

Let's model it layer by layer.

The Income Tax Picture — Before Missouri Votes

Right now, Kansas City residents earning $115,000 face a two-layer income tax hit that most people underestimate.

Missouri's current top income tax rate is 4.8%, reduced from prior years through a series of legislatively mandated rate cuts. After Missouri's standard deduction (~$14,600 for single filers, mirroring federal) and a personal exemption of ~$2,100, your Missouri taxable income is approximately $98,300. Applying Missouri's graduated brackets — where the 4.8% top rate kicks in above roughly $9,000 in taxable income — your total state income tax bill is approximately $4,556.

Then Kansas City layers on a city earnings tax: 1% on all wages earned by residents. On $115K, that's an additional $1,150.

Total income tax burden in Kansas City: $5,706 per year.

In Austin, Texas: $0. No state income tax, no city income tax.

That's a $5,706 annual take-home advantage for Austin. But we're not done — not by a long shot.

Property Tax: Where Texas Takes It Back

Texas funds schools and local government primarily through property taxes, and Travis County (Austin) runs an effective rate of approximately 2.1–2.2% on assessed value. With Austin's median home price sitting around $480,000 in 2025 — down from the 2022 peak, but still elevated — your annual property tax bill in Austin is approximately $10,200.

Jackson County (Kansas City, MO) carries an effective property tax rate of roughly 1.2%. With KC's median home price around $245,000, your annual property tax is about $2,940.

The property tax gap: Austin costs $7,260 more per year in property taxes alone.

That single line item wipes out the entire income tax advantage and then some. If you're a homeowner comparing these two cities, Texas's "no income tax" story is substantially offset by what you pay in property taxes. We've examined this same dynamic in our comparison of Austin vs. Miami's total tax burden — and the pattern holds across Texas metros. It's also worth noting in our post on $115K in Austin vs. Charlotte, where Austin's post-pandemic housing costs similarly compress the income tax advantage.

Sales Tax: A Wash (For Now)

Kansas City's combined sales tax — Missouri state at 4.225% plus city and county levies — lands around 8.5% for most purchases in KC proper. Austin's combined rate (Texas state 6.25% plus city 2.0%) is 8.25%. On $50,000 in annual spending:

Kansas City: $4,250
Austin: $4,125

A $125 annual difference — essentially noise at this salary level. But hold that number, because Missouri's pending ballot proposal could move this dramatically.

The Full Annual Tax + Housing Comparison (Current Law)

Here's the complete picture for a $115K earner, modeled in both renter and homeowner scenarios.

Homeowner (10% down, 6.5% mortgage rate):

Cost Category	Kansas City	Austin
State income tax	$4,556	$0
City earnings tax	$1,150	$0
Annual mortgage P+I	$14,328	$29,376
Property tax	$2,940	$10,200
Sales tax (on $50K spending)	$4,250	$4,125
Annual total	$27,224	$43,701
Annual gap	—	$16,477 more

Renter (median 2BR, 2025 market):

Cost Category	Kansas City	Austin
State income tax	$4,556	$0
City earnings tax	$1,150	$0
Annual rent (median 2BR)	$13,800	$23,400
Sales tax (on $50K spending)	$4,250	$4,125
Annual total	$23,756	$27,525
Annual gap	—	$3,769 more

Kansas City comes out ahead in both scenarios — by $16,477/year for homeowners and $3,769/year for renters. The "no income tax" narrative doesn't survive contact with Austin's housing and property tax numbers. This is exactly the kind of full-picture comparison Vontari runs so you're evaluating your actual financial position, not just the income tax headline.

Now Add Missouri's Tax Vote: How the Math Could Shift

Here's where the analysis gets genuinely interesting. According to the Institute on Taxation and Economic Policy's State Rundown from April 23, 2026, Missouri lawmakers have passed legislation placing a major tax restructuring proposal before voters. The ask: approve higher sales taxes to offset the potential elimination of the state individual income tax, which currently makes up nearly two-thirds of Missouri's general fund.

This is not a marginal adjustment. Missouri collects roughly $9 billion annually from its individual income tax. Replacing that revenue would require a meaningful sales tax increase — potentially pushing Kansas City's combined rate from ~8.5% to 11–12%.

What does that mean for a $115K earner in Kansas City?

Estimated post-elimination scenario:

Tax Type	Current KC	Post-Elimination KC	Austin
State income tax	$4,556	$0	$0
City earnings tax	$1,150	$1,150	$0
Sales tax ($50K spend, ~11%)	$4,250	$5,500	$4,125
Subtotal	$9,956	$6,650	$4,125

Note that the KC city earnings tax is a separate municipal ordinance — it would not automatically disappear alongside the state income tax elimination.

Even after the vote, Austin still wins on income and sales taxes combined by about $2,525/year. But add back the housing and property tax gap — $7,260/year more in property taxes for Austin homeowners — and Kansas City remains the lower total-burden city by a significant margin.

The key insight: Missouri's income tax elimination would most benefit high-income renters. A Kansas City renter earning $115K would save roughly $3,300/year from the swap. A homeowner's calculation barely changes, because the property tax differential already tilts so heavily toward KC.

For a look at how Missouri's existing structure stacks up against a state that already operates without income tax, our analysis of $110K in Seattle vs. Kansas City walks through why the sales-tax-for-income-tax trade-off matters more than the headline rate.

Purchasing Power: The Number Nobody Quotes

The Bureau of Labor Statistics publishes Regional Price Parities (RPP) — a standardized measure of how far your dollar goes relative to the national average. Based on BLS 2022 RPP data:

Kansas City metro RPP: approximately 89.0 (11% below the national average — your dollar goes further)
Austin metro RPP: approximately 97.5 (2.5% below national average)

To equalize purchasing power between the two cities:

$115,000 in Kansas City equals approximately $125,980 in Austin.

In practical terms, Austin would need to pay you nearly $11,000 more per year just to maintain the same standard of living you have in Kansas City — before accounting for any tax differences. Stack that on top of the $3,769–$16,477 annual cost gap, and the "Austin upgrade" starts looking more like a pay cut in disguise.

The Homeownership Reality Check

A 2022 study from the American Enterprise Institute, cited by Realtor.com, found that homeownership rates for 40-year-olds dropped from 69% in 2000 to 58% in 2022. Separately, the National Association of Home Builders reports that Baby Boomers now control 34.1% of the total housing stock — 29.6 million homes worth $13.8 trillion in housing value — which constrains inventory and keeps prices elevated in high-demand metros.

Austin sits squarely in that high-demand, low-inventory category. The math shows why homeownership is slipping out of reach for $115K earners there:

Kansas City: Median home price-to-income ratio = 2.1x ($245K home on $115K income)
Austin: Median home price-to-income ratio = 4.2x ($480K home on $115K income)

The traditional 28% gross income guideline for housing costs puts your ceiling at $2,683/month on $115K.

Kansas City PITI (principal, interest, tax, insurance): approximately $1,550/month — well within range ✓
Austin PITI: approximately $3,400/month — significantly over the threshold ✗

Austin's combination of post-pandemic price appreciation and Texas's high effective property tax rate has pushed homeownership out of reach for many $115K earners — even as the no-income-tax pitch keeps drawing them in. You can model your specific affordability threshold against your down payment, salary, and spending patterns at Vontari before making any commitments.

The Honest Summary

There's no universal answer here — but here's where the math actually lands for a $115K earner:

Renters who prioritize take-home pay: Austin saves $5,706 in income taxes but costs $9,600 more in rent. Kansas City is cheaper overall by ~$3,800/year.
Homeowners: Kansas City wins by $16,477/year when you account for mortgage size and property tax.
After Missouri's income tax vote (if it passes): Kansas City gets more competitive on income taxes, but the total-burden advantage for homeowners remains firmly in KC's favor.
Purchasing power comparison (BLS RPP): Kansas City's dollar buys roughly 9.5% more than Austin's — the equivalent of $10,980/year in additional effective income.

The only scenario where Austin clearly wins on financial terms at $115K is if you're a long-term renter who spends relatively little (keeping sales tax exposure low), earns significant investment income that bypasses the KC city wage tax, and expects to never purchase property. For almost everyone else, Austin's no-income-tax headline is a marketing advantage, not a financial one.

Missouri's ballot proposal adds a layer of uncertainty — if the vote passes and the state income tax disappears, that narrows the gap for renters but doesn't flip the comparison. If it fails, Kansas City stays exactly where it is: meaningfully cheaper in total cost for most $115K households.
