How does Miami County's Fiscal Health Stack Up?
Vol. III, No. 300. A Look at What the Numbers From Seven Neighboring Counties Actually Tells Is About How Miami County Manages Public Funds
Every year, Ohio counties publish a Comprehensive Annual Financial Report — a document that almost no one reads and almost everyone should. These reports are the closest thing to an honest accounting of how local government is actually performing. Not the budget projections. Not the press releases. The actual results.
This publication pulled the CAFRs from seven counties in our region — Miami, Darke, Shelby, Champaign, Clark, Montgomery, and Greene — and ran the numbers side by side.
Important caveat: before you draw conclusions, understand what you’re looking at: this is a genuinely diverse group. Darke County is largely agricultural. Shelby County has a strong manufacturing base. Greene County is anchored by Wright-Patterson Air Force Base and the commercial corridors that surround it. Montgomery County is an urban county with a population of more than 537,000, a regional transit system, and the service demands that come with being the economic center of the metro area. Champaign County, with fewer than 39,000 residents, is the smallest in the group.
Comparing these counties directly is a little like comparing a family farm to a regional hospital. The scale is different. The mission is different. But the fundamentals of fiscal management — are you living within your means, building equity, and generating enough revenue to serve residents — those apply to everyone.
Here’s what the data says about Miami County.
The Lowest Bill in the Room
Miami County collects $943 per resident in total governmental revenue. That’s the lowest of any county in our peer group. The next closest is Greene County at $998. At the top sits Champaign County at $1,418 per capita — nearly 50% more per resident than Miami County collects.
On the expense side, Miami County spends $908 per resident — also the lowest in the group. Montgomery County spends $1,552 per capita, the most by a wide margin.
That combination — low revenue, low spending — produces a surplus of just $35 per capita. Granted, it’s a thin margin, but it is a margin. Every county in this peer group except Montgomery finished in the black. Miami County’s surplus is modest; Champaign County’s is $342 per capita, Greene County’s is $154. But the point is that Miami County is not spending more than it earns.
The Property Tax Story
Here is where the data gets interesting for Miami County residents.
Miami County collects $122 in property tax per capita — the lowest of all seven counties, and not particularly close. The peer group average, excluding Miami, is $213 per capita. Montgomery County collects $289. Greene County collects $270. Even Darke County, a largely rural agricultural county, collects $166 per capita in property taxes.
This is not an accident, but it may not be what you think. Ohio property tax collections reflect millage rates and property values — and Miami County’s commissioners have historically placed very few countywide levies on the ballot. The property tax levies Miami County voters typically see are for schools, township fire and EMS service, and other highly local purposes. Countywide government tend to be rare and if they do exist, they are very specialized services that the County doesn’t have direct involvement such as libraries and mental health. So the lean property tax base isn’t a story about voter resistance — it’s a story about what county leadership has chosen to ask for.
What’s notable is that despite that lean revenue structure, Miami County has still managed to build a governmental net position of $1,702 per capita — second in the peer group, behind only Greene County ($1,978) and ahead of Montgomery County ($1,668), Clark, Shelby, Darke, and Champaign. The county has accumulated significant fiscal equity while keeping tax collections at the lowest level in the region. That is a legitimate accomplishment — and it raises a reasonable question: if the county can build this kind of equity on this little revenue, what would more intentional investment actually produce?
The Sales Tax Cushion
Miami County charges a 7.00% total sales tax — lower than Darke, Shelby, Champaign, and Clark (all at 7.25%), and lower than Montgomery County’s 7.50% (which includes a transit levy). Only Greene County’s 6.50% rate is lower.
At that 7.00% rate, Miami County collects $222 per capita in sales tax. That’s competitive. Darke County collects $235 at 7.25%. Clark County collects $242 at 7.25%. Miami County is generating comparable sales tax revenue while charging less — a sign of a healthy retail and commercial base relative to its population.
Here's a number worth sitting with. Miami County commissioners have placed a measure on the May primary ballot that would raise the county sales tax by 0.50% — from 1.25% to 1.75% — on a temporary basis to fund a new jail and corrections facility. Based on Miami County's current taxable retail, that half-cent increase would generate approximately $9.9 million in additional revenue per year.
That's not pocket change. It's also not permanent — the temporary structure means the rate would sunset once the facility is paid off, returning the county to its current rate. For context, if the county had simply raised its rate to 1.50% to match most of its neighbors — Darke, Shelby, Champaign, and Clark counties all charge 1.25% at the county level — it would generate roughly $5.0 million more annually. Voters in May are being asked to go further than that, and for a specific purpose.
The Montgomery County Cautionary Tale
No analysis of this peer group is complete without addressing Montgomery County directly. It is the only county in this group running a structural deficit — spending $241 more per resident than it collects in revenue, for a total gap of more than $129 million.
To be fair, context matters. Montgomery County’s sales tax includes a 0.50% transit levy dedicated to the Greater Dayton RTA — those dollars can’t be redirected to close the general fund gap. Montgomery also carries the cost of urban infrastructure and services that smaller counties don’t face. And its total governmental net position of $1,668 per capita shows that decades of prior fiscal management built real equity.
But a $129 million annual deficit is not a rounding error. It is a warning sign that the county is spending down reserves built over decades. For Miami County residents and leaders, it is a useful illustration of what happens when revenue and expenditure structures get out of alignment — and why maintaining that $35 per-capita surplus, thin as it is, matters.
So Is Miami County Well Managed?
By the core measures of governmental finance, yes, The county lives within its means. It has built strong governmental net equity. It collects taxes efficiently relative to its rates. It does not carry the structural imbalances visible in Montgomery County.
The bottom line for Miami County residents is this: your county government is fiscally conservative, operationally lean, and currently solvent. The question is not whether it is managing today’s dollars responsibly — the data suggests it is. The question is whether the current revenue structure is adequate for tomorrow’s demands.
That’s a conversation the data invites, but only residents and their elected officials can finish.
