A $100,000 home in the part of Harrison Township that is also inside Dayton’s city limits and the Northridge school district owes about $3,277 a year in property tax for tax year 2025. That is the 3rd-highest of Ohio’s 4,479 taxing districts, by the Ohio Department of Taxation’s rates, and about 2.5 times the statewide median of $1,321. Four of the township’s taxing districts rank in Ohio’s top 15.

Four districts, four bills
A taxing district is a combination of the governments that tax a piece of land. Harrison Township has four: the township’s own territory and the parts that are also inside the City of Dayton, each split between the Northridge and Dayton school districts.
| Taxing district | School district | $100,000 home | $200,000 home | Rank in Ohio |
|---|---|---|---|---|
| Harrison Township, inside Dayton city limits | Northridge Local Schools | $3,277 | $6,554 | #3 of 4,479 |
| Harrison Township, inside Dayton city limits | Dayton City Schools | $3,099 | $6,197 | #5 of 4,479 |
| Harrison Township | Northridge Local Schools | $2,983 | $5,966 | #7 of 4,479 |
| Harrison Township | Dayton City Schools | $2,792 | $5,585 | #15 of 4,479 |
| Dayton, not in a township (for comparison) | Dayton City Schools | $1,992 | $3,984 | #302 of 4,479 |
Who levies it
Every bill in the township is made up of the same pieces. On a $100,000 home in the township’s own territory with Dayton schools, the township’s levies come to about $1,107 of the $2,792 bill, or 40%. The schools take about $1,095.
| Levied by | Dayton part, Northridge | Dayton part, Dayton schools | Township, Northridge | Township, Dayton schools | Dayton, not in a township |

Yearly tax on a $100,000 owner-occupied home. “Library, parks and Sinclair” is Dayton Metro Library, Five Rivers MetroParks and Sinclair Community College. The career center is the Miami Valley Career Technology Center, which levies only in the Northridge district.
Why the Dayton parts pay the most
The two highest districts are land that the City of Dayton annexed from Harrison Township but that the state’s rate tables still list in both. Those homes pay the township’s levies, about 48 mills, and the city’s, about 10 mills, which come to about $306 a year on a $100,000 home. Dayton homes outside any township pay the city’s levy but no township levy, which is why the same school district costs about $1,107 more a year inside the township.
That’s how Ohio law works. Annexing land to a city doesn’t by itself take it out of the township: the city has to ask the county commissioners to redraw the township’s lines (R.C. 503.07). The Ohio Supreme Court put it this way in 2012: land annexed from a township “remains part of that township until” the city acts to change the boundaries (Sugarcreek Twp. v. Centerville). Land annexed under the state’s expedited process can never be excluded and “remains subject to the township’s real property taxes” (R.C. 709.023).
The city’s levy also isn’t trimmed by the state’s reduction factors, which lower most voted levies as property values rise. Dayton’s 10 mills are charter and inside millage, which the law leaves out of that reduction (R.C. 319.301), so the full rate is charged.
The township’s levies
Harrison Township levies 47.97 mills in all. Most of it is for public safety:
| Purpose | Gross mills | On a $100,000 home | Levies (year passed) |
|---|---|---|---|
| Police | 23 | $457 | 13 (2008), 4 (2013), 6 (2016) |
| Fire and EMS | 15.75 | $392 | 6.75 (2006), 4 (2015), 5 (2024) |
| Roads | 4.58 | $99 | 0.2 (inside), 0.76 (inside), 3.62 (2010) |
| General operations | 4.64 | $160 | 0.64 (inside), 4 (2024) |
The township runs its own fire department, with two stations. Police service is a contract with the Montgomery County Sheriff’s Office; the township paid $517,722 for May 2026. In its 2026 budget as amended in May, property taxes were expected to bring in $12,587,538 of the township’s resources, and trustees appropriated $23,587,739 across all funds.
| Fund | 2026 property tax (est.) | 2026 appropriation |
|---|---|---|
| Police District | $5,559,987 | $6,926,069 |
| Fire District | $4,275,054 | $6,235,875 |
| Road and Bridge | $1,198,636 | $1,753,858 |
| General Fund | $1,553,860 | $3,222,113 |
A small tax base
A mill raises less where property is worth less, so it takes more mills to raise the same money. By the state’s school district profiles, Northridge Local Schools had $121,601 of taxable property per pupil and Dayton City Schools $167,244, against $267,733 for the median of Ohio’s 606 school districts. The same pattern runs through the bill: gross levies in the township’s own territory with Dayton schools add up to 150.24 mills, and the state’s reduction factors bring that down to 88.35 for homes, which is still among the highest effective rates in Ohio.
The reduction factors are themselves large here. Dayton City Schools’ levies total 74.41 mills on paper and 35.74 for homeowners, because most voted levies in Ohio can’t raise more money when values go up; the rate shrinks instead.
What residents can check
The county auditor has each property’s exact bill, and the township posts its budgets and meeting minutes at harrisontownship.org. Our Ohio property tax map ranks all 4,479 districts, and the calculator shows any value.
That raises a question for the people who pay these bills: do you feel you’re getting what you pay for? What would you change?
