The claim this page tests
Before the mechanism and the map — the actual thing being argued, stated plainly, so it can be checked rather than assumed.
When a PID or TIF district diverts the tax increment from new growth into a restricted debt service fund, the county, school district, fire district, and water district never get credit for that growth on their books — even though they still have to serve it: more rooftops, more students, more calls, more water and road demand.
If the increment can't cover both the debt payments and the real cost of that added service burden, the gap has only two places to come from: a higher certified tax rate on everyone outside the district, or cuts to services / reserves.

Same list price on both sides on purpose — Utah State Auditor Tina Cannon has said PID homes can carry closing costs similar to a comparable home with infrastructure baked into its price, so a buyer discount isn't something to assume without a specific comp.

UIPA and MIDA can each create their own subsidiary PID inside a project area, layering a second real assessment on top of a base PID. RSDZ (HB 507) adds a further state revenue skim on top of that. Each is a separate legal entity with its own bond schedule — no single body tracks the combined total, and there is no required disclosure of the stack until closing.
A real Utah County example
Renters don't buy a home, so the PID cost doesn't show up as a line item on a tax bill the way it does for an owner. It shows up as extra charges tacked onto the rent instead — and there's a legal loophole that lets a landlord do that even when the base rent itself is capped by law. Here's exactly how, using real numbers from an actual Utah County building.
Step 1. A federal affordability program (LIHTC) caps the base rent a landlord can legally charge — in this example, $1,290/month.
Step 2. The building sits inside a PID, so the landlord passes the property's PID assessment straight through to tenants as a separate charge — $225/month here. That charge isn't "rent," so the cap doesn't touch it.
Step 3. The landlord adds more separate, mandatory fees on top — things labeled "smart home services," "utility technology package," or similar — $300/month here. Also not "rent," also outside the cap.
The result: a unit legally marketed and reported as "affordable" that actually costs the tenant far more than the cap was ever supposed to allow — and every individual piece of it is legal on its own.
Drag the sliders to see how the total changes. The defaults below are the real, documented figures from 120 & 220 Bend in Utah City (Vineyard, Utah County).
Why this is legal
The affordability law only regulates the word "rent." It says nothing about property tax pass-throughs or fees the landlord chooses to bill under a different name. Split the cost into three separate line items, and each one is individually compliant — even though added together they defeat the entire point of the cap.
Why a renter has less protection than a homeowner here
A homeowner at least gets a public Truth-in-Taxation hearing before their county's tax rate can rise. A renter gets none of that. Utah has no rent control of any kind, and a landlord can raise rent by any amount with as little as 15 days' notice on a month-to-month lease, or whenever a lease renews — no hearing, no disclosure requirement, no public process at all. If the PID assessment goes up, or a second UIPA/MIDA layer gets added to the property later, that cost simply shows up in the next rent increase.
Who actually benefits from the "economic development" pitch
The state's own official summary of the law creating PIDs describes them as "an exciting new economic development tool for Cities and Counties along with property owners." What that tool actually provides the developer is access to low-interest, tax-exempt municipal bond financing — normally reserved for governments — to build infrastructure they would otherwise have to fund out of pocket or through costlier private loans. PID debt is not a liability of the city or county that creates it.
Since buyers typically pay the same list price whether or not a home sits inside a PID, the savings from that cheaper financing stay with the developer as profit margin. The repayment obligation — the PID assessment itself — gets transferred forward onto whoever buys or rents there, for the life of the bond.

Not every mechanism shows up on your bill
PID and IFD add a real charge to your own bill. RDA, HTRZ, and the first-home/homeownership zone tools redirect existing tax revenue growth instead — they don't show up on your bill at all. The cost lands on the city, county, and school district, not on you directly.
| Tool | How it works | Adds to your bill? |
|---|---|---|
| PID / IFD | New assessment or mill levy, bonds repaid by owners directly. | Yes |
| UIPA / MIDA subsidiary PID | UIPA or MIDA creates its own PID inside a project area, stacking a second assessment on the same property. | Yes |
| RDA | Growth in tax revenue above a frozen base year redirected to a redevelopment fund. | Not directly |
| HTRZ | Same tax increment mechanism as RDA, targeted near transit. | Not directly |
| First Home / Home Ownership zones | Same tax increment mechanism, aimed at starter-home affordability. | Not directly |
PID, IFD, and UIPA/MIDA subsidiary PIDs create a genuinely new charge that lands on your tax bill. RDA, HTRZ, and the two zone tools instead redirect the growth in existing tax revenue away from the city, county, and school district for the life of the district, usually 10-20 years. Your own bill looks the same as any neighbor's — but the diverted revenue can still raise the base rate that everyone outside the zone pays.
What the diverted growth was supposed to sustain
Utah's upward-mobility advantage rests on the same tax base that TIF and PID diversion carve into.
Once bonds are issued, there's no backing out
What a PID or HTRZ locks in for the public versus what it locks in for the developer, once construction starts.
| Dynamic | The public downside | The developer upside |
|---|---|---|
| Trigger point: once bonds are issued and construction starts, the entire framework locks in. | ||
| Commitment | Taxing entities are fully committed and cannot easily back out without facing catastrophic default. | Secures guaranteed, long-term public funding for infrastructure upfront. |
| Market stalls | The public must continue paying off the issued bonds even if the project completely stalls. | Insulated from initial infrastructure debts; retains ownership of the underlying assets. |
Who oversees the stacking mechanism
MIDA — the authority that can create a subsidiary PID inside a Utah County project area, stacking a second assessment on top of a base PID — has board seats tied to other appointments rather than standing for independent re-approval. One documented example: a board member's MIDA term is tied to his separate Governor's Office of Economic Opportunity Executive Director term, which "expires in March 2027, and automatically renews for four-year intervals thereafter." Oversight of a board with reach into Utah County developments isn't on a fixed public review cycle of its own.
What's confirmed, what isn't yet
Confirmed, on the record
- State Auditor Tina Cannon's office confirmed the statewide PID debt figures directly (meeting Aug 10, 2026; written follow-up Aug 7, 2026 total).
- Cannon's office confirmed the increment-diversion mechanism in writing — that diverted revenue funds a restricted debt service fund the taxing entities never receive, and that the only levers to cover a resulting shortfall are a higher certified rate under Truth in Taxation, or cuts to services/reserves.
- Sweetwater Industrial Park CRA #3 figures pulled from Eagle Mountain Redevelopment Agency's April 2023 public hearing notice.
- Utah City PID and RDA status confirmed via Vineyard City creation resolutions and the city's own redevelopment agency plan-progress page.
Not yet confirmed
- Whether individual taxing entities disclose PID/TIF diversion as a specific cause when presenting rate increases to the public under Truth in Taxation — this is the open question currently out to the Auditor's office.
- A statewide, entity-by-entity accounting of which counties/districts have raised rates specifically because of increment diversion.
In Cannon's own words (from correspondence)
"...the taxing entities are stuck paying for the added service burden without getting the added revenue to cover it. That gap has to be filled from somewhere, and the only place they can pull it from is the tax rate on everyone else..."
"It gets made up by everyone else paying a higher rate, or by everyone else getting less service — there's no third funding source that appears to cover the gap."
Smaller pie, same slice taken out
A separate compounding effect, this one in Utah County — what happens to TIF diversion when the district absorbing it gets cut into pieces.
Alpine School District — 84,000+ students, the largest in the state — is splitting into three new districts starting July 2027: Central (Lehi, American Fork, Highland, Cedar Hills, Alpine, part of Draper), West (Eagle Mountain, Saratoga Springs, Cedar Fort, Fairfield), and South (Orem, Pleasant Grove, Lindon, Vineyard).
Right now, any TIF/PID diversion inside Alpine's boundaries is absorbed by an 84,000-student district's full budget — the dollar loss is real, but diluted across a huge base. Once the split happens, that same diverted dollar amount lands entirely on whichever new, much smaller district contains that project. The tax base shrinks dramatically; the diversion doesn't.
The gap between the official line and the mechanism
Utah County's own messaging states the district division "isn't expected to significantly impact tax collection or school funding," pointing to the state's per-pupil WPU funding as the stabilizer. That's true for state funding — but WPU is not the local property tax base, which is exactly where TIF/PID diversion operates. The county's reassurance doesn't address the mechanism this section documents.
