Reforming Personal Property Tax, E-Filing, and Educating the Public in Missouri with Bob Boyer

About this Episode

The property tax conversation in Missouri keeps circling back to personal property — the annual ritual of declaring your vehicles, watching values bounce around based on a pricing guide nobody uses in real life, and writing a check right before Christmas. Bob Boyer, the Jefferson County Assessor, has spent seven years trying to make that process less painful while simultaneously pushing for the systemic reforms that could actually fix what's broken. His argument is straightforward: you don't have to blow up the system to make it work better, but you do have to stop pretending the current one is working as designed.

Bob came to the assessor's office from county council and, before that, professional land surveying. That combination — political instinct, technical fluency, and an outsider's willingness to question inherited processes — shows up in nearly every initiative he describes.

The 75/25 Problem

Here's a number that should make every Missouri assessor wince: personal property represents roughly 25% of Jefferson County's assessed valuation, but it consumes about 75% of the office's labor. Bob has 13 employees dedicated to personal property out of a staff of 32. The math doesn't work, and everyone in the profession knows it.

The calls to eliminate personal property tax entirely are loud in Missouri, but Bob is clear-eyed about the obstacles. "It's ingrained in our constitution, it's ingrained in state statutes. How do you pull all that back out? There's a lot of work that would have to be done." He's not dismissing abolition — he describes himself as a limited-government guy — but he's practical about the revenue hole it would leave behind for school districts, fire departments, and ambulance services that depend on it.

What he is pushing for is a fundamental change in how vehicles are valued. The current statute requires assessors to use the October trade-in value from the prior year, sourced from a JD Power publication that almost nobody in the real world treats as authoritative. "Nobody ever uses JD Power when you trade something in. You get laughed at if you said, hey, my JD Power value is this."

The alternative Bob and the Missouri State Assessors Association are advocating mirrors actual appraisal theory: start with the manufacturer's suggested retail price and apply a standardized depreciation schedule. It's the same logic assessors already use for real estate — base value, minus depreciation, equals assessed value. The debate in the legislature now centers on the length of that depreciation curve, with some anti-tax legislators pushing for seven years versus the proposed twenty. But the principle itself has traction.

Making Government Invisible (In a Good Way)

When Bob arrived in the assessor's office, it was mailing out roughly 100,000 pieces of paper every year. Staff opened envelopes, scanned forms, and manually keyed data into the system. He saw it for what it was: a process designed around 1970s technology persisting into the smartphone era.

By 2018, Jefferson County had full electronic filing for personal property declarations. Last year, about 44,000 taxpayers used it, and the number grows by four to five thousand annually. Two years ago, Bob helped get the law changed to allow email delivery of personal property lists — something that sounds trivially obvious but required an actual statutory change. Around 10,000 people now receive their lists electronically.

The downstream effects are real. The office eliminated four part-time positions that existed solely to open and sort mail. Counter traffic for real estate inquiries dropped 90% after the office put its property database, GIS viewer, and FAQs online. "Nobody likes to interact with the government," Bob says. "So if we can make it quick and easy for them, and we get the information in the system accurately, it's a win-win for both people."

This isn't about technology for its own sake. It's about recognizing that the friction of the process is itself a source of taxpayer resentment — and that reducing friction is something an assessor can actually control.

The Hancock Amendment Gap

The policy conversation Bob raises about Missouri's Hancock Amendment deserves more attention than it typically gets. The amendment is supposed to function as a taxpayer protection: if assessed values grow beyond 5% or the consumer price index (whichever is lower), taxing districts must roll back their levy so taxpayers don't absorb the full increase.

In theory, it's elegant. In practice, school districts have found a workaround. Only the operating levy is subject to Hancock's rollback requirement. If a district still has ceiling room on its debt service levy, it can raise that rate to keep overall revenue stable — effectively neutralizing the protection the amendment was supposed to provide. "So now the taxpayer, if we raise our values 10, 15%, the taxpayers see the brunt of that tax increase. And they weren't supposed to."

Bob and the assessors association are working with the State Tax Commission to bring this to the General Assembly. The argument isn't radical: just make the system work the way it was originally designed. The assessor sets the value; the taxing district sets the rate. When those roles blur, accountability disappears, and the assessor becomes the scapegoat for a tax increase that was really a levy decision.

Guarding the Tax Base

Bob's office recently won a State Tax Commission case against a Lowe's store that invoked the dark store theory — the argument that a functioning big-box retail property should be valued as if it were vacant or blighted. The opposing appraisal relied on comparable sales from distressed areas of North St. Louis, which had no market relevance to Festus, Missouri. Jefferson County hired its own appraiser and prevailed.

He frames these fights in terms of equity, not ideology. "Property taxes are like a big piece of pie. Somebody's gonna eat it." When large corporations successfully reduce their valuations through aggressive appeals or secure exemptions under charitable-purpose umbrellas, the share borne by residential taxpayers increases. The schools still need their funding. The fire department still runs.

Key Takeaway

The Missouri personal property tax isn't going away anytime soon, and pretending otherwise wastes political energy that could be spent fixing the mechanics — standardized depreciation, electronic filing, and a Hancock Amendment that actually does what voters thought it would. The assessor's job isn't to make people love their tax bill; it's to make sure they can understand it.
