NW 142nd Street runs through Clive like most streets in this suburb do, lined with driveways and mailboxes and not much to mark it as anything other than a street. But it also happens to be roughly where Polk County ends and Dallas County begins. Cross it, and the county assessing your home changes. So does the school district your address is zoned for. So, in the end, does the total tax bill you'll pay on a home that looks, on paper, identical to the one three blocks over.
Portals and market summaries treat Clive as a single number: one median price, one city, one set of schools. That framing isn't wrong so much as incomplete. Clive is genuinely split between two counties, and that split does real work on what a buyer ends up paying and where their kids end up enrolled. If you're comparing Clive against Waukee, West Des Moines, or Urbandale using a single average, you're comparing against a number that Clive itself doesn't fully agree with.
Two counties, one city
Clive sits in both Dallas and Polk counties, a fact confirmed by the city's own property tax page, which notes plainly that Polk and Dallas County assessors each independently assess market value for homes inside Clive's borders. That's not a technicality that only shows up in a county recorder's office. It's the reason the same city can point two different directions when a buyer asks "which schools?"
According to Wikipedia's Clive, Iowa page, the Polk County side of Clive falls under the West Des Moines Community School District, while the Dallas County side, west of that same NW 142nd Street line, is zoned to the Waukee Community School District. Two households on the same cul-de-sac could, depending on exactly where that cul-de-sac sits relative to the county line, be zoned for entirely different districts. Neither is described here as better. They're simply different systems, with different levies, different bond schedules, and different boards setting budgets independently of each other.
What actually stays the same
Here's the part that keeps this from being a simple story about one side costing more than the other. The City of Clive's own municipal tax rate applies identically no matter which county you're in. For fiscal year 2026-2027, that rate is $9.92 per $1,000 of taxable valuation, the same figure the city has held for multiple years running. If Clive's city government were the only layer on a tax bill, there would be no split story to tell.
The state-level piece is uniform too. Iowa caps how fast statewide residential valuations can grow in aggregate, and each year the state calculates a rollback percentage that determines how much of a home's assessed value actually gets taxed. For 2026, SmartAsset reports that the rollback ratio is 47.43 percent, and it applies the same way whether a home sits in Polk County or Dallas County. Reassessment also runs on the same statewide clock: Iowa reassesses real property every odd-numbered year, a cycle set by the Department of Revenue, not by any individual county.
So two of the four layers stacked on a Clive tax bill are identical everywhere in the city. It's the other two, the county and the school district, where the numbers start to diverge.
Where the difference actually lives
| Layer | Who sets it | Same across Clive, or does it vary by county line? |
|---|---|---|
| City levy | City of Clive | Same everywhere: $9.92 per $1,000 (FY2026-2027) |
| State rollback | Iowa Dept. of Revenue | Same everywhere: 47.43% for 2026 |
| County assessment | Polk County Assessor or Dallas County Assessor | Independent assessors, independent valuation timing |
| School district levy | West Des Moines Community Schools or Waukee Community School District | Separate boards, separate levies, separate bond schedules |
A consolidated levy comparison Waukee published for its FY2023 budget cycle put the combined city, county, and school rate for a Clive property zoned to Waukee schools and Dallas County at roughly $33.54 per $1,000 of taxable value. That figure is a few budget cycles old now and shouldn't be read as this year's exact number, but it illustrates the mechanism clearly: the consolidated rate a homeowner actually pays isn't a single Clive number at all. It's whatever the city rate, the county rate, and the school levy add up to for that specific parcel.
This isn't unique to Clive, and the clearest proof of that sits just to the east. West Des Moines' own finance department states outright that its city spans four counties and six school districts, which produces nine different total tax rates inside one set of city limits. Clive's version of this is smaller in scale, two counties instead of four, essentially two school-district outcomes instead of six, but it's the same underlying pattern playing out across the metro. A city boundary and a tax boundary are not the same thing, and treating them as interchangeable is where buyers get surprised at closing.
Why the timing matters as much as the geography
The county line explains which levies apply to a given address. The reassessment calendar explains why the exact dollar figure can shift even without anyone moving. Iowa's property tax cycle runs eighteen months from the January assessment date to the first tax payment, and full reassessments happen every other year. That lag means a home's assessed value on the books today reflects market conditions from the most recent odd-year assessment, not necessarily this month's sale price. A buyer closing on a Clive home in an even year is working from a valuation set the year before, with the rollback and levy layers applied on top.
There's also a credit worth knowing about regardless of which county you land in. Iowa's Homestead Credit reduces the taxable value of an owner-occupied primary residence by the first $6,500 of valuation, a benefit that applies the same way in both counties once you've filed for it with the appropriate assessor.
What to actually ask before comparing two Clive listings
If you're weighing a Clive address against another suburb, or against a different block of Clive itself, the median price alone won't tell you what you need to know. A few concrete questions get you there faster than a portal search:
- Which county is the parcel in, Polk or Dallas? Both counties maintain online assessor tools, including the Polk County Assessor's search portal and Dallas County's interactive mapping tool, and either one will confirm the county for a specific address in a few clicks.
- Which school district is the address zoned to, West Des Moines Community Schools or Waukee Community School District? This follows directly from the county answer, since the boundary lines up with the county split.
- What is the current consolidated levy for that specific tax district, not just the city's portion? The city rate is only one line item on a bill that includes county and school levies too.
- When was the property last reassessed, and does that valuation reflect a full odd-year reassessment or a mid-cycle adjustment from a recent sale or improvement?
None of these questions require a specialist to answer. They just require asking about the right layer instead of the Clive-wide average.
A quick FAQ
Does living on one side of the county line change anything besides schools and taxes? Based on what the city and county both publish, the divide is specifically about which assessor's office values the property and which school district it's zoned to. City services, like Clive's parks and public safety, are provided citywide regardless of county.
How do I find out which side of the line a specific address falls on? The Polk County Assessor's office and Dallas County's GIS mapping tool both let you search a specific parcel and confirm the county, which in turn tells you the school district zoning.
Does a higher consolidated levy mean that side of Clive is a worse place to buy? Not necessarily. A higher combined rate often reflects a district's own budget choices, bond schedules, or levy structure rather than anything about the home or the neighborhood itself. It's one more number to weigh alongside price, condition, and fit, not a verdict on the area.
If you're comparing a specific Clive address against homes in Waukee, West Des Moines, or elsewhere in the metro and want the actual consolidated numbers for that parcel rather than a citywide average, that's exactly the kind of digging BVZ Homes does before a client ever writes an offer.
