Non-ad valorem assessments on your Florida property tax bill: solid waste, fire, stormwater, MSBU, CDD

How non-ad valorem differs from ad valorem

The two halves of the Florida property tax bill answer two different questions. The ad valorem section answers "what is your property worth, and what percentage of that value funds general government?" The non-ad valorem section answers "what specific services does your parcel benefit from, and what is your share of the cost?"

Three structural differences flow from that.

Basis of charge. Ad valorem is computed as (Taxable Value ÷ 1,000) × millage. Doubling your home's value doubles the ad valorem tax. Non-ad valorem is computed per unit of benefit: a flat dollar amount per dwelling, a per-acre rate, a per-Equivalent Residential Unit rate, or a per-front-foot rate. Doubling your home's value does not change the non-ad valorem charge.

Caps and exemptions. The Save Our Homes 3 percent cap (Article VII, §4(d), Florida Constitution) and the 10 percent non-homestead cap (FS 193.1554 and 193.1555) limit how much the ad valorem assessed value can rise year over year. Neither cap applies to non-ad valorem assessments. The 51,411 USD homestead exemption in 2026 also applies only to ad valorem. A non-ad valorem fire assessment of 250 USD is the same 250 USD whether the homeowner is homesteaded or not.

Statutory home. Ad valorem is grounded in Article VII of the Florida Constitution and FS chapters 192 to 200. Non-ad valorem assessments are grounded in FS 197.3632 (the uniform collection mechanism), plus a service-specific statute for each type: FS 190 for CDDs, FS 125.01(1)(q) for MSBUs, FS 403.0893 for stormwater, FS 403.706 for solid waste programs, and FS 170.01 for the broader catalogue of services that may be funded by special assessment.

A non-ad valorem assessment can become a tax lien on the property and lead to a tax certificate and ultimately a tax deed sale, exactly like unpaid ad valorem taxes. The statutory consequence of non-payment is the same. Owners sometimes assume the non-ad valorem section is a "soft" line they can deprioritize. It is not.

How non-ad valorem charges get onto the bill

FS 197.3632 sets a uniform statewide procedure that any local government can use to collect a non-ad valorem assessment on the property tax bill alongside ad valorem taxes.

The local government (county, city, or special district such as a CDD) adopts a budget for the service in question. It then calculates the per-unit assessment, prepares a non-ad valorem assessment roll, holds a public hearing with notice to affected owners, and certifies the roll to the County Property Appraiser by September 15 and to the County Tax Collector by September 15 of the same year. The Tax Collector merges the certified roll into the consolidated property tax bill mailed in early November.

The same calendar that governs ad valorem taxes governs non-ad valorem assessments: the bill is mailed in early November, the 4 percent early-payment discount runs to November 30, the 3 percent discount to December 31, the 2 percent to January 31, the 1 percent to February 28 or 29, and the no-penalty deadline is March 31. April 1 makes the entire bill (ad valorem plus non-ad valorem) delinquent.

For a Canadian owner, this means the non-ad valorem section is paid in the same single transaction as ad valorem property tax. There is no separate billing cycle and no separate due date.

The five most common non-ad valorem assessments

Below is the line-by-line walk-through of what you actually find in the non-ad valorem section of a typical Florida property tax bill. Not every property has every line. Whether each line appears depends on the parcel's location, the type of community, and whether the local government has elected to use the FS 197.3632 mechanism for that service.

1. Solid waste (garbage, recycling, yard waste)

Statutory basis: FS 197.3632 for the collection mechanism, FS 403.706 for the recycling program duties of counties.

What it funds: residential garbage pickup, single-stream recycling, yard waste, bulky item pickup, and the operation of the county's transfer stations and household hazardous waste drop-off centers. The fee covers collection (the trucks and routes) and disposal (the landfill or waste-to-energy facility).

How it is calculated: a flat annual fee per single-family dwelling, set each year by the county or municipal solid waste department. Multifamily and commercial properties are usually billed differently or under separate commercial contracts.

Where it does not appear: condominium units in HOA-managed buildings rarely have a solid waste line on the individual owner's tax bill. The building has a private dumpster contract, and the cost is in the HOA fee instead.

A dedicated guide on this assessment is published separately: Florida garbage and recycling by county.

2. Stormwater utility fee

Statutory basis: FS 403.0893, which authorizes counties and municipalities to create a stormwater utility and adopt fees sufficient to plan, construct, operate, and maintain the stormwater management system.

What it funds: the public stormwater system that handles runoff from streets and impervious surfaces, including catch basins, culverts, retention ponds, outfalls, and treatment of polluted runoff before it reaches surface waters. In a state where most of the population lives within ten miles of the coast and where summer thunderstorms drop two to four inches of rain in an hour, this is non-trivial infrastructure.

How it is calculated: typically per Equivalent Residential Unit (ERU), where one ERU represents the average impervious-surface footprint of a single-family detached home. A small condo might be billed at 0.5 ERU. A large home with a detached pool deck and a big driveway might be billed at 1.5 ERU. Some local governments charge a flat rate per single-family dwelling regardless of size.

Where it does not appear: properties in unincorporated rural areas not served by a public stormwater system. Properties served by a CDD whose stormwater is bundled into the CDD assessment do not see a separate stormwater utility line.

3. Fire protection assessment

Statutory basis: FS 125.01(1)(q), which authorizes a county to establish a Municipal Service Benefit Unit (MSBU) for any or all of the unincorporated area to fund fire protection, law enforcement, beach erosion control, recreation, water, streets, sidewalks, lighting, drainage, transportation, indigent health care, and other essential services. The same statute also allows for a Municipal Service Taxing Unit (MSTU), which is the ad valorem version (a millage rate inside a defined sub-area). Many counties run a hybrid: an MSBU for fire and a separate MSTU for EMS.

What it funds: fire stations, fire trucks, firefighter salaries, training, dispatch, hydrants, and fire-prevention programs in the area covered by the MSBU.

How it is calculated: a flat annual fee per single-family dwelling, often differentiated by use category (residential, commercial, industrial, agricultural). Some counties weight by square footage of the structure rather than per dwelling.

Where it does not appear: cities that fund fire protection from their general municipal millage rather than through a separate MSBU. In those cities, fire is buried inside the city ad valorem millage on the top half of the bill. The total cost may be similar; the line item is in a different section.

4. Other MSBU assessments (lighting, paving, drainage, canal, security)

Statutory basis: FS 125.01(1)(q) for the MSBU mechanism, FS 170.01 for the broader catalogue of services that can be funded by special assessment.

What it funds: street lighting in a specific subdivision, the original paving of a private or sub-standard street, drainage improvements in a flood-prone neighbourhood, canal dredging in a waterfront community, neighbourhood security patrols. The MSBU is created at the request of a homeowners group (51 percent petition threshold in many counties), and the assessment is levied only on properties within the defined unit.

How it is calculated: depends entirely on the unit's enabling ordinance. Common methods are per-front-foot (for paving), per-dwelling (for lighting), or per-acre (for canal maintenance).

Where it does not appear: most properties. MSBUs are geographically narrow. A typical Florida property tax bill in a non-master-planned area has zero MSBU lines, or one or two small ones (often lighting). Bills in older waterfront communities, however, can carry several MSBU lines simultaneously.

5. Community Development District (CDD)

Statutory basis: FS chapter 190 (the Uniform Community Development District Act of 1980). A CDD is a special-purpose unit of local government authorized to plan, finance, build, operate, and maintain community-wide infrastructure (roads, water, sewer, stormwater, parks, recreational amenities) within a defined master-planned community.

What it funds: typically two distinct components. - Debt service repays the tax-exempt municipal bonds the CDD issued in its early years to build the original infrastructure (roads, water and sewer mains, stormwater ponds, entry features, recreational amenities). The debt service portion is fixed for the term of the bonds (usually 20 to 30 years) and disappears when the bonds are fully amortised. - Operations and maintenance (O&M) funds the ongoing upkeep: landscaping, lake management, lighting maintenance, district administration, insurance, and amenity operations. O&M is set annually by the district's board of supervisors and continues indefinitely.

How CDDs differ from HOAs. This is the single most common confusion for buyers. An HOA is a private nonprofit corporation governed by FS chapter 720 that enforces deed restrictions and operates private amenities, billing dues directly to homeowners under a private contract. A CDD is a unit of local government governed by FS 190 that issues bonds, levies non-ad valorem assessments collected by the County Tax Collector, and operates under Florida sunshine and ethics laws. A property in a master-planned community often pays both: the CDD on the November tax bill and the HOA on a separate monthly or quarterly invoice. The two are not interchangeable, and one cannot be substituted for the other.

Worked example: two homes, two different non-ad valorem totals

Consider two single-family detached homes, each with a Just Market Value of 500,000 USD, both purchased by Canadian non-residents in 2026. Both are in unincorporated portions of Manatee County, on the Gulf Coast of Florida. Both are subject to the same county and school millage on the ad valorem side. The non-ad valorem sections diverge sharply.

Property A: Older neighbourhood in unincorporated Manatee County, no CDD. - Solid waste assessment: 320 USD - Stormwater utility: 90 USD - Fire protection MSBU: 280 USD - No lighting, paving, or drainage MSBU - No CDD assessment - Non-ad valorem total: 690 USD per year

Property B: Lakewood Ranch village, single-family home in a recently developed CDD. - Solid waste assessment: 320 USD (same county service) - Stormwater utility: not separately billed (bundled in the CDD) - Fire protection MSBU: 280 USD (same county service) - CDD debt service: 1,800 USD - CDD operations and maintenance: 600 USD - Non-ad valorem total: 3,000 USD per year

The ad valorem property tax on the two properties is nearly identical (both at 500,000 USD JMV with the same county and school millage, both subject to the 10 percent non-homestead cap because the Canadian owners cannot claim homestead). The non-ad valorem section, however, costs Property B owner 2,310 USD per year more, every year, with the CDD debt service portion locked in until the bonds amortise approximately 25 years from the village's construction.

In year one, the gap is 2,310 USD. In year ten, with the CDD line largely unchanged, the gap is approximately 23,000 USD. Property B owner is also paying HOA dues for amenity operations, which often run lower than in Property A's neighbourhood (because the CDD is funding amenities that an HOA-only community would have to fund through HOA dues). The all-in carrying cost gap depends on that offset; it is usually smaller than 2,310 USD per year, but it is rarely zero.

Florida and Quebec: structural differences in how local governments fund services

The Canadian reference province here is Quebec, where most CanadaFlorida readers come from.

The structural takeaway. Quebec embeds in the general municipal tax most of what Florida itemises in the non-ad valorem section. A Quebec property tax bill has fewer line items but a higher mill rate (because it is doing more work). A Florida property tax bill has more line items but a lower mill rate on each. The total cost is not necessarily different; the visibility is. The CDD has no Quebec analogue. A Canadian buying in a Florida master-planned community is buying into a financing structure that does not exist in Quebec, and that structure's line on the tax bill is the financial signature of the development.

Common mistakes Canadian buyers make

These six errors recur frequently enough to merit explicit treatment.

1. Underwriting only the ad valorem line. Listings, MLS data, and online tax estimators commonly quote the prior owner's ad valorem property tax and stop there. The non-ad valorem section can add 500 USD per year (for a basic property in an established neighbourhood) to 3,500 USD per year (for a property in a new master-planned CDD). A pre-purchase budget that ignores the non-ad valorem section understates the true carrying cost of the property by anywhere from 5 percent to 40 percent.

2. Confusing the CDD assessment with the HOA fee. They are different. The CDD is a non-ad valorem assessment on the November tax bill, payable to the County Tax Collector, lien-secured against the property. The HOA fee is a private contractual obligation, billed monthly or quarterly by the association, with separate enforcement mechanisms under FS chapter 720. A property can have one, the other, both, or neither. Many Florida master-planned communities have both, and the buyer must budget both.

3. Assuming the CDD line will stay the same forever. The CDD has two components. The debt service portion (typically 60 to 80 percent of the total CDD assessment) is fixed by the bond schedule and disappears when the bonds amortise (usually 20 to 30 years from the village's construction). The O&M portion (typically 20 to 40 percent) continues indefinitely and can rise or fall annually with the district's adopted budget. A first-time buyer who reads only "CDD: 2,500 USD per year" misses the longer-term reality that the assessment may drop to 600 USD per year once the bonds are paid, then continue at that lower level. This is a meaningful long-term consideration for retirees planning a 20-year hold.

4. Mistaking an MSBU for an HOA. An MSBU is a unit of local government. Its assessments are public records, its budget is public, its meetings are subject to Florida sunshine law, and its assessment is on the tax bill as a non-ad valorem line. An HOA is a private corporation. Some buyers see "lighting MSBU: 75 USD" on the bill and confuse it with HOA dues. They are not the same and they are not interchangeable.

5. Failing to verify each non-ad valorem line at the parcel level. "Average" or "typical" CDD figures published online are useful as ranges, never as commitments. Within a single CDD, two lots may carry different assessments depending on lot size, frontage, or use category. The only authoritative number is the most recent tax bill for the specific parcel under offer, which the seller is required to disclose under FS 689.265 (CDD disclosure) and which the County Tax Collector also publishes online for every parcel.

6. Ignoring the closing-statement proration. The non-ad valorem section is prorated between buyer and seller at closing, on a 365-day calendar, alongside the ad valorem property tax. A buyer who only verifies the ad valorem proration and skips the non-ad valorem proration misses a significant credit or debit. This is a closing-agent or attorney issue, not a county issue. Verify both prorations on the settlement statement before signing.

How to read your specific bill

Three steps locate the non-ad valorem section on any Florida property tax bill.

First, identify the County Tax Collector for the property (a Google search for "[county] tax collector" returns the official site). Each TC publishes the property tax bill online, searchable by address or parcel number. The bill is the same document mailed in November.

Second, scroll past the ad valorem section. The ad valorem section is at the top, organised by taxing authority (county general fund, county debt service, school district required local effort, school district capital improvement, school district discretionary, city, water management district, hospital district, library district). Each line shows the millage rate and the resulting tax.

Third, locate the non-ad valorem section, usually labelled "Non-Ad Valorem Assessments" or "Special Assessments". This section lists each non-ad valorem charge on a separate line, with the levying authority's name (the county solid waste department, the stormwater utility, the fire MSBU, the specific CDD, etc.) and the dollar amount. The total of all non-ad valorem lines plus the total ad valorem tax equals the bottom-line amount due in March.

For each non-ad valorem line, the underlying budget and assessment roll are public records. The County Tax Collector's office or the levying authority itself can provide the adopted budget, the unit-of-measurement basis, and the methodology document.

Closing: how non-ad valorem assessments are prorated

Florida property tax (ad valorem and non-ad valorem combined) is annual. The owner of record on January 1 of a given year is liable for the full tax for that year, but the November bill is not yet known on January 1. Closings that occur during the year therefore prorate the estimated annual bill between buyer and seller.

The proration is normally done on the settlement statement (CD or ALTA) at closing. The closing agent uses the most recent year's bill as a baseline (with a notation that the actual proration is subject to adjustment when the actual bill issues), and credits the buyer for the seller's share of the year-to-date and debits the seller correspondingly. If the most recent bill includes a CDD assessment, an MSBU, a stormwater fee, and a solid waste fee, all four are part of the proration calculation.

Two pitfalls are worth flagging. First, in the year of an underlying assessment increase (a CDD rate change, a fire MSBU adopting a new rate, a city adopting a new stormwater utility), the prior year's bill understates the current year's likely bill. Buyers should ask the closing agent whether any rate changes have been adopted but not yet billed. Second, the FAR/BAR contract typically calls for proration based on the prior year's bill, not the current year's adopted but not yet billed roll. This default works in stable years and creates after-closing reconciliation in years of rate changes; the contract may be modified by mutual agreement.

For a Canadian buyer on a B-2 visit who is signing the closing remotely (via attorney-mailed documents), the non-ad valorem proration is a line on the settlement statement that should be reviewed in CAD and USD, not just glanced at. A 500 USD discrepancy in proration is real money, and the closing agent will not catch errors that the parties themselves do not flag.

Actionable checklist before making an offer

1. Pull the prior year's full property tax bill from the County Tax Collector's website for the specific parcel. Read both the ad valorem and the non-ad valorem sections.
2. Identify each non-ad valorem line. Note the levying authority and the dollar amount.
3. If a CDD line appears, request the seller's CDD disclosure (FS 689.265) showing the debt service amount, the O&M amount, the bond maturity date, and any pending or adopted budget changes.
4. If an MSBU line appears, request the ordinance creating the MSBU and the methodology document.
5. Confirm that the closing agent is prorating both ad valorem and non-ad valorem at the correct ratios.
6. Build a carrying-cost spreadsheet in USD that includes ad valorem property tax, every non-ad valorem line, HOA fees (if any), insurance (homeowners plus separate hurricane plus flood), HOA master-policy assessments, and operating costs (utilities, lawn, pool, snowbird concierge, internet).
7. Compare the all-in monthly carrying cost across two or three candidate properties before negotiating price. Two properties listed at the same price can have a 200 to 400 USD per month gap in non-ad valorem and HOA combined.

FAQ

Are non-ad valorem assessments tax-deductible? For a US tax return on rental income (Form 1040-NR), most non-ad valorem assessments tied to current-year services (solid waste, stormwater, fire, MSBU O&M, CDD O&M) are deductible against rental income as a current expense. The CDD debt service portion is generally treated as a non-deductible capital cost in the IRS's view, because it is repaying bonds that financed permanent infrastructure, not paying for current services. For Canadian tax reporting (T776 rental statement), the same general logic applies: current-year service costs are deductible against gross rents; bond debt service repayment is not. Verify with a cross-border tax professional for the specific facts of your property.

Can I appeal a non-ad valorem assessment? Yes, but the appeal does not go to the county Value Adjustment Board (VAB), which only hears ad valorem assessment appeals. Each non-ad valorem assessment is appealed to its levying authority. CDD assessments are challenged at the CDD board public hearing on the budget. Stormwater utility fees are challenged at the city or county public hearing. The mechanism is set by FS 197.3632(4), which requires the levying authority to hold a public hearing each year before adopting the assessment roll and to mail or publish notice to affected owners.

What happens if I do not pay the non-ad valorem section but pay the ad valorem? The bill is treated as a single bill. Partial payments are not generally accepted by the Tax Collector. If the bill is unpaid by April 1, the entire bill (ad valorem and non-ad valorem combined) is delinquent, a tax certificate may be sold against the property, and the lien runs against the parcel until cured.

Is a CDD's debt service tax-deductible against my rental income? Generally no. The debt service portion is treated as a non-deductible capital recovery on infrastructure. The O&M portion of the same CDD is generally treated as a deductible operating expense. The two are usually shown on separate lines of the bill. Verify with a cross-border tax professional.

Why do some Florida properties have no non-ad valorem section at all? Because no service uses the FS 197.3632 mechanism for that parcel. Solid waste may be billed monthly by the city (Tampa, for example, runs municipal collection with monthly billing rather than non-ad valorem). Stormwater may not have been adopted as a utility. Fire may be funded by general city millage in the ad valorem section instead of an MSBU. The absence of a non-ad valorem section does not mean the services are free; it means they are funded through other channels.

Can the CDD assessment be paid off in advance to remove the lien? Sometimes. FS 190 allows a CDD to permit prepayment of the bond debt portion at the discretion of the district, subject to the bond documents. The owner contacts the district manager for a payoff figure. Prepayment is most common when the owner is selling the property and the buyer prefers a lien-free closing. Prepayment is not always allowed; some bond documents prohibit it.
