RDA, HTRZ & Tax Increment Financing
These three tools decide where a growing share of your property taxes go — and they are often the least understood line in local budgets. Here is what they are and how they actually work, in plain language.
Three Terms, One Idea
RDAs and HTRZs are programs. Tax increment financing is the mechanism both of them run on. Get the mechanism and the rest falls into place.
Redevelopment Agency
A local government agency that uses future property-tax growth to pay for development inside a defined project area.
In Utah these are governed by the Community Reinvestment Agency Act (Title 17C). The board is usually the city council or county commission wearing a second hat. They create “project areas” to spur private investment, remove blight, build infrastructure, or encourage housing.
Housing & Transit Reinvestment Zone
A newer, transit-focused version of the same tool, created by the Utah Legislature in 2021 to build housing near transit.
Established under the Housing and Transit Reinvestment Zone Act (Title 63N). An HTRZ sits around rail stations and major transit corridors and uses tax increment to encourage denser, mixed-use, and more affordable housing — with state-level review through the HTRZ Committee.
Tax Increment Financing
The funding mechanism underneath both. It captures the growth in property-tax revenue and redirects it to the project.
TIF is not a new tax. It freezes the property value in an area at a “base” amount. As development raises values, the taxes on that increase — the “increment” — are routed to the agency instead of flowing to every taxing entity, including school districts.
How Tax Increment Financing Splits Your Taxes
When a project area or zone is created, the property value is frozen at a base. Everything below the line keeps funding schools and local government. Everything the area grows above the line — the increment — is captured to pay for the project.
Illustrative only. The key takeaway: during the capture period a school district keeps collecting on the frozen base, but it does not see the taxes from the new growth until the area sunsets — even though that growth can add students who need to be served today.
The Life Cycle of a Project Area
1. A project area or zone is drawn
A city or county designates the boundaries of an RDA project area or an HTRZ around transit. The total assessed property value inside it is recorded as the frozen “base value.”
2. Development raises property values
New buildings, housing, and improvements increase assessed values inside the area above the base. That difference is the “increment.”
3. The increment is captured
Property taxes on the base keep flowing to schools, the city, and the county as before. The taxes on the increment are redirected to the agency for a set number of years.
4. Eventually the area “sunsets”
After the agreed term ends, capture stops and the full, higher property value flows to every taxing entity — including the school district — for the first time.
RDA / CRA vs. HTRZ
Same financial engine, different rulebooks and purposes.
| RDA / CRA | HTRZ | |
|---|---|---|
| Created under | Community Reinvestment Agency Act (Utah Code Title 17C) | Housing & Transit Reinvestment Zone Act (Title 63N), enacted 2021 |
| Where it applies | City or county “project areas” targeted for development or blight removal | Areas around rail stations and major transit corridors |
| Primary goal | Spur private investment, jobs, infrastructure, and redevelopment | More — and more affordable — housing, density, and transit ridership |
| Money is typically spent on | Infrastructure, land assembly, and developer reimbursements/incentives | Transit-oriented infrastructure, structured parking, and housing incentives |
| Increment captured | A negotiated share of the increment from each participating taxing entity | Up to a statutory cap (commonly cited at up to ~80%) for a limited term |
| Duration | Set per project area — commonly in the 15–25 year range | Time-limited — generally up to about 25 years of capture |
| Oversight & approval | Agency board + a taxing-entity committee that must consent | State HTRZ Committee review + Governor’s Office of Economic Opportunity, plus local approval |
Figures such as percentages and durations are set by Utah statute and individual agreements and can change — always confirm against the current code and the specific project documents.
Where Education Dollars Enter the Picture
School districts are among the largest property-tax recipients in Utah. When an RDA or HTRZ captures the increment, a portion of the school district's share of the growth is redirected to the project for the life of the agreement.
There can be sound reasons to do this — infrastructure and housing have real public value. The point is not that the tools are wrong, but that the trade-offs should be visible, debated, and disclosed. That is the gap we work to close.
- Districts usually must formally consent to contribute their increment.
- Growth can add students now, while the new tax revenue is deferred for years.
- The real fiscal impact is often buried in interlocal agreements few people read.
Questions to Ask About Any Project Area
- 1What is the base value, and how much increment is being captured?
- 2Which taxing entities consented — and did the school district?
- 3How many years does the capture run before it sunsets?
- 4Is there a published cost-benefit analysis the public can read?
