Fiscal Note Version – New
Description
Senate File 356 relates to property tax levies and the number of county seats in a county. The
Bill has five divisions:
• Division I — County Budgets and Levy Rates — Applies to FY 2025 and after.
• Division II — City Budgets and Levy Rates — Applies to FY 2025 and after.
• Division III — Public Education and Recreation Tax Levy (PERL) — Applies to FY 2028
and after, except where noted.
• Division IV — Brucellosis and Tuberculosis Eradication Fund Levy — Applies to
FY 2025 and after.

Note on Property Tax Rates
All property tax rates used in this document are reflected as rates that are applied per $1,000 of
taxed property value. Taxed property value is the value determined through the assessment
process, adjusted (reduced) for any rollback for the property class, and after property tax
exemptions have been applied.
Division I — County Budgets and Levy Rates
Division I Background
Iowa Code chapter 331 (County Home Rule) provides the authority for counties to tax real
property, with additional authority provided in Iowa Code chapter 422D (Optional Taxes for
Emergency Medical Services) and Iowa Code chapter 28E (Joint Exercise of Governmental
Powers). Certain county tax levies apply to all taxed property within the county (general levies),
while other levies apply only to property that is outside of incorporated cities (rural levies).
Properties located in cities are subject to only the general levies, while rural properties are
subject to both general and rural levies.
Current law authority for county general levies includes:
• Iowa Code section 331.423(1) — The authority for general services is limited to a maximum
of $3.50.
• Iowa Code section 331.426 — The authority for additions to the $3.50 general services levy
is unlimited, but use of the additional levy requires a finding of one or more of the following
seven circumstances:
• An unusual increase in population.
• A natural disaster or other emergency.
• Unusual problems related to major new functions required by State law.
• Unusual staffing problems.
1
 • Unusual financing required to permit the continuance of a program that provides
substantial benefit to county residents.
• Unusual need for a new program that provides substantial benefit to county residents.
• A reduced or unusually low growth rate in the county property tax base.
• Iowa Code section 331.424(1) — If the general services levy and additions are not sufficient,
supplemental general services levies are allowed for any of nine enumerated services,
including:
• Charges the county is required to pay by statute for inpatient and outpatient substance
abuse and for certain persons attending special schools and hospitals.
• Court-ordered foster care.
• Elections and voter registration.
• Employee benefits.
• Tort liability and other insurance.
• Maintenance and operations of courts.
• Court-ordered costs associated with domestic relations conciliation.
• A joint county indigent defense fund pursuant to an agreement with one or more other
counties.
• Maintenance and operation of an emergency management agency.
• Iowa Code section 331.424B — A general levy of up to $0.0675 is available for the repair
and maintenance of cemeteries.
• 2019 Iowa Code section 331.424A(6) — A former (repealed) general levy used to fund the
County Mental Health and Disabilities Services Fund. Funding for this function is now
provided through a State General Fund appropriation.
• Iowa Code section 331.422(3) — A general levy for debt service payments.
• Iowa Code section 422D.5 — A general levy of up to $0.75 for emergency medical services
(voter-approved).
Current law authority for county rural services levies includes:
• Iowa Code section 331.423(2) — The authority for the rural services levy is limited to a
maximum of $3.95.
• Iowa Code section 331.426 — The authority for additions to the $3.95 rural services levy is
unlimited, but use of the additional levy requires a finding of one or more of seven unusual
circumstances listed above as additions to the general services levy.
• Iowa Code section 331.424(2) — If the rural services levy and additions are not sufficient,
supplemental rural services levies are allowed for two enumerated services, including:
• Employee benefits associated with rural services employees.
• An aviation authority.
• Iowa Code section 28E.22 — If approved by voters, a levy of up to $1.50 is available for the
purposes of a 28E agreement related to unified law enforcement.
In addition to the above general and rural levies, Iowa Code section 331.425 allows
voter-approved additions to levies otherwise specified.
Figure 1 provides a breakdown of the amount of revenue raised and the number of counties
utilizing the property tax levies available to counties. Information is provided for FY 2017 and
FY 2023. From FY 2017 through FY 2023, the statewide average total countywide levy for all
purposes decreased from $6.35 to $5.94, and the average rural level for all rural purposes
decreased from $3.36 to $3.22. During the period, two law changes occurred that directly
impacted the revenue side of county budgets. Funding for the County Mental Health and
Disabilities Services Fund was transferred to the State General Fund, and the State General
Fund appropriation to counties to backfill the property tax reduction that was the result of a
2
10.00% reduction in the taxable value of commercial and industrial property began a phase-out
period.

Division I Description
The Bill makes the following changes:
• Consolidates several county functions that are currently financed through a combination of
general county services, rural county services, additions to general/rural county services,
and supplemental levies.
• Creates additional limits on the maximum allowed general and rural county services tax
rates.
• Lowers the dollar amount threshold requirements for counties to enter into leases,
lease-purchase contracts, loan agreements, and bonded indebtedness without an election
following a petition. Thresholds are lowered by 30.00%.
• Requires a county’s Annual Financial Report to include a list of bonds, notes, and other
obligations.
The Bill creates new county-specific general services tax rate limits for FY 2025 that are based
on FY 2024 rates, and for future years, county-specific tax rates are based on growth in county
taxed value and county tax rates. Fiscal year 2025 general services tax rates may not be higher
than the rates established for the same purposes for FY 2024. For FY 2026 and succeeding
years, the application of new county general service levy limits will fall into one of three groups
depending on the situation in each county:
• Group 1 — Counties with a current year tax rate of $3.50 or lower and with budget year tax
base growth in excess of 3.25%: Through a formula, counties in this group will have the
growth in their budget year maximum property tax revenue dollars reduced by 3.25
percentage points. A county will have the ability to access tax base growth above 3.25% for
the year.
• Group 2 — Counties with tax base growth above 2.50% that are not included in the first
group (their tax base growth does not exceed 3.25% or their current year tax rate is above
$3.50 or both): Through formula, counties in the second group will have the growth in their
3
 budget year maximum property tax revenue dollars reduced by 2.50 percentage points.
They will retain tax base growth above 2.50% for the year.
• Group 3 — Counties with a tax base growth of 2.50% or less: Counties in this group will be
able to utilize all growth in the property tax base, and if their current year rate is below
$3.50, they may also raise their budget year general services rate to $3.50.
Rural county services tax rates are limited in the same manner as discussed above, but the limit
is based on the rate of growth in a county’s rural tax base and the current year’s rural county
services levy rate, with references to the $3.50 tax rate changed to $3.95.
Year-to-year, individual counties may and often will fall into a different group depending on their
budget year tax base growth and current year tax rate. Regardless of the group a particular
county occupied in a previous year, its maximum general or rural services tax rate returns to
$3.50 if the county’s applicable tax base growth does not exceed 2.50% for a year. At any time,
a county may establish a tax rate below the calculated maximum. However, doing so will
reduce the county’s maximum tax rate should it fall within the first or second group the following
year.
Division I Assumptions and Fiscal Impact
County General and Rural Services
Actual statewide general services tax base growth between FY 2017 and FY 2023 exceeded
3.25% for each of the six years. Additionally, the FY 2023 statewide average general services
levy is just above $3.50 at $3.55. However, there is considerable variation in tax rates and tax
base growth rates, and only four counties have an FY 2023 general services tax rate, including
the cost of courts, of $3.50 or lower and also experienced growth in their tax base of more than
3.25% for each of the six years.
Actual statewide rural services tax base growth between FY 2017 and FY 2023 exceeded
3.25% for each of the six years. Additionally, the FY 2023 statewide average rural services levy
is well below $3.95 at $3.18. Of the 99 county rural services levies, including rural services
additions, the rates of only three counties exceed $3.95. Three-quarters of counties
experienced at least one year of rural tax base growth below 2.50% over the six years. This
statistic means that under the Bill, most counties will be occasionally allowed to increase their
rural services levy to as high as $3.95.
The fiscal impact of the new levy rate limits is examined in this Fiscal Note through examples
based on historical annual growth rates of nine counties as well as the FY 2023 general and
rural services tax rates of those counties.
• The future growth in the tax base of individual counties is not known. For this analysis the
actual annual tax base rate of growth for each of the nine example counties from FY 2017
through FY 2023 is used to model future tax base growth patterns for the counties. For
each county, the tax base rate of growth for FY 2018 is assumed for FY 2025, and the
FY 2019 tax base rate of growth is assumed for FY 2026, etc.
• The first year of the new tax rate limits is based on FY 2024 actual tax rates. Since FY 2024
rates are not available, FY 2023 rates are used in this analysis and assumed to be the
FY 2024 rates.
• The FY 2024 general services tax rates become the FY 2025 rate limits, and the FY 2024
general services tax rate is the sum of:
• The basic general services tax rate of $3.50.
• The basic general services additions tax rate.
• The portion of the general services supplemental tax rate that represents the
maintenance and operation of courts. For the analysis of the examples, the FY 2023
4
 budgeted court expenditure total for each county is converted to a property tax rate, with
the result added to the general services levy only for those counties utilizing a general
service supplemental levy for FY 2023.
• The FY 2024 rural services tax rates become the FY 2025 rate limits, and the FY 2024 rural
services rate is the sum of:
• The basic general services tax rate of $3.95.
• The basic rural services additions tax rate (if any).
Example Counties — General Services Levy
Figure 2 provides general services tax rate and tax base statistics for nine example counties.
• The left portion provides a projection of the FY 2024 general services tax rate limit that is
based on FY 2023 actual rates and on a calculation of the portion of each county’s
supplemental levy that represents maintenance and operation of courts.
• The right portion provides annual average tax base growth, low annual tax base growth, and
high annual tax base growth for each of the counties.

The following analysis of counties uses current tax rates and historical annual tax base growth
for each county to produce examples of how the new tax rate limits may work given differing
situations that could occur in the various counties. Future growth will not be the same as past
growth, so the results should not be used to make conclusions about how the additional tax rate
limits included in this Bill might impact any specific county.
The general tax base of Dickinson County expands more than 3.25% for each of the six years
(average annual rate = 4.59%), and the county general services tax rate is below $3.50 ($2.45)
for FY 2024. This places the county in Group 1 for all years of the projection, which means that
the maximum general services tax rate is reduced for FY 2026 through FY 2030 and the rate is
projected to equal $2.09 for FY 2030. Over the six projection years, the county general services
tax base expands 30.87% and property tax revenue increases 11.53%.

The general tax base of Dallas County expands more than 3.25% for each of the six years
(average annual rate = 8.03%), and the county general services tax rate is below $3.50 ($2.77)
for FY 2024. This places the county in Group 1 for all years of the projection, which means that
the maximum general services tax rate is reduced for FY 2026 through FY 2030 and the rate is
projected to equal $2.36 for FY 2030. Over the six projection years, the county general services
tax base expands 58.92% and property tax revenue increases 35.44%.
The general tax base of O’Brien County expands more than 3.25% for each of the six years
(average annual rate = 8.29%), and the county general services tax rate equals $3.56 for
FY 2024. Due to a tax rate above $3.50 for FY 2024 and FY 2025, the county would fall into
Group 2 for FY 2026, but with a projected tax rate below $3.50 for FY 2026, the county would
fall into Group 1 for the remaining four years of the projection, which means that the maximum
general se
