Property Tax Protests and CAM Billing: How They Interact

By Angel Campa, Founder, CapVeri

The Two-System Problem

Property tax protests and CAM reconciliation operate on different timelines, and the gap between them creates most of the problems in this article.

CAM reconciliation runs on a calendar year. Statements go out in Q1 or Q2 covering the prior year's expenses. The tax amount included in that reconciliation is whatever was billed by the county assessor.

Property tax protests, depending on the jurisdiction, can take 6 months to 3 years to resolve. A protest filed in May 2025 against the 2025 assessment might not settle until October 2026 — after the 2025 CAM reconciliation has already been delivered and paid.

When the protest succeeds, the landlord receives a refund. That refund belongs partly to the tenants who were billed based on the higher amount. Getting the money to the right tenants, in the right amounts, at the right time is where controllers lose sleep.

Protest Timing Relative to Reconciliation

The Timeline Mismatch

Here is a typical sequence for a $4.2M assessed value property in Harris County, Texas:

DateEvent
January 2025County issues 2025 assessment notice: $4.2M
May 2025Landlord files protest challenging the $4.2M valuation
July 2025Informal hearing — no resolution
October 2025Formal hearing scheduled
December 2025Year ends; property tax paid at full $4.2M assessment ($92,400 at 2.2%)
March 20262025 CAM reconciliation delivered to tenants (includes $92,400 in taxes)
June 2026Formal hearing results in settlement: $3.8M value
August 2026County issues refund of $8,800 ($400K value reduction × 2.2%)

The reconciliation went out in March 2026 with $92,400 in taxes. The actual tax should have been $83,600. Tenants overpaid their share of $8,800 — and the refund did not arrive until five months after the statements were delivered.

Three Approaches to Handling the Timing Gap

Approach 1: Reconcile on taxes paid, adjust later.

Include the full tax payment in the reconciliation. When the refund arrives, issue a credit or supplemental statement. This is the most common approach because it is operationally simple and matches the actual cash outflow.

Pros: Matches cash basis; statements go out on time Cons: Requires a second communication to tenants; creates a "floating" adjustment

Approach 2: Accrue for the expected reduction.

If the protest is filed and you have a reasonable estimate of the likely reduction, include the estimated (lower) tax amount in the reconciliation. When the actual refund arrives, true up the difference.

Pros: More accurate initial statement; smaller adjustment later Cons: Requires judgment on the protest outcome; if the protest fails, you under-billed

Approach 3: Hold the reconciliation until protest resolves.

Delay the reconciliation statement until the tax amount is final. This produces the most accurate statement but may violate lease deadlines.

Pros: One accurate statement; no follow-up needed Cons: Late delivery (may violate lease terms); delays tenant payments

Recommendation: Approach 1 for most situations. Use Approach 2 only when the protest outcome is highly predictable (e.g., the informal hearing already produced a verbal agreement). Never use Approach 3 — the risk of missing a lease-mandated delivery deadline outweighs the convenience of a single statement.

Distributing Tax Refunds to Tenants

The Proportional Allocation

When a tax refund arrives, each tenant is entitled to their pro-rata share of the reduction — based on the same allocation methodology used in the original reconciliation.

Example: A 150,000 SF retail center receives an $8,800 tax refund.

TenantLeased SFPro-Rata ShareRefund Allocation
Tenant A22,50015.00%$1,320.00
Tenant B37,50025.00%$2,200.00
Tenant C15,00010.00%$880.00
Tenant D30,00020.00%$1,760.00
Vacant45,00030.00%$2,640.00
Total150,000100.00%$8,800.00

The landlord absorbs the vacant portion ($2,640). This is correct — the vacancy share of the original tax was either not billed or was covered by gross-up. The refund follows the same logic.

Tenants Who Left

What happens when the refund arrives 18 months after the reconciliation, and Tenant C vacated the building 6 months ago?

The answer depends on the lease:

  • If the lease addresses tax refunds explicitly: Follow the lease. Some leases provide that refunds for periods during the tenant's occupancy are credited or refunded regardless of current occupancy.
  • If the lease is silent: Most jurisdictions treat the overpayment as a debt owed to the former tenant. Issue a refund check.
  • If the tenant defaulted or was evicted: Check whether the refund can be applied against unpaid rent or other amounts owed. Consult counsel before withholding.

Practical tip: When a tenant vacates, confirm whether any tax protests are pending for periods during their occupancy. If so, keep their forwarding address and banking information on file. Processing a $880 refund check is straightforward. Tracking down a former tenant to deliver it is not.

Mid-Year Refunds

When a refund arrives mid-year — say, August 2026 for a 2025 tax year — you have two options for distribution:

  1. Credit against current CAM estimates: Reduce the monthly CAM estimate for the remaining months of the year. If Tenant A is owed $1,320 and pays $3,200/month in estimates, reduce September–December by $330/month.

  2. Lump-sum credit on next reconciliation: Include the credit in the 2026 reconciliation statement, reducing the 2026 tax amount by the refund.

Option 1 is more tenant-friendly (they get the money sooner). Option 2 is operationally simpler. Either works — just be consistent across all tenants.

The Risk of NOT Protesting

The Fiduciary Argument

Most property controllers think of tax protests as optional — a way to save money if the assessment seems high. But there is a growing body of arbitration decisions suggesting that landlords have an obligation to manage operating expenses reasonably, which includes protesting above-market assessments.

The argument goes like this: if the county assesses your property at $4.2M and comparable properties sold for $3.5M, the excess assessment ($700K) generates roughly $15,400 in unnecessary tax ($700K × 2.2%). That $15,400 flows through CAM to tenants. If you did nothing to reduce it, the tenants overpaid because of your inaction.

A tenant auditor who finds that you did not protest an above-market assessment will argue that the excess tax is not a "reasonable operating expense" under the lease. Some arbitrators have agreed, reducing the CAM charge by the estimated excess tax.

The Dollar Math on Not Protesting

ScenarioAssessmentMarket ValueExcess Tax (2.2% rate)Tenant CAM Impact
Mild overassessment$4.2M$3.9M$6,600/year$4,620 (at 70% occupancy)
Moderate overassessment$4.2M$3.5M$15,400/year$10,780
Severe overassessment$4.2M$2.8M$30,800/year$21,560

The cost of filing a protest is typically $0 (you can do it yourself) to $5,000–$15,000 (using a tax consultant on contingency, typically 25–35% of the savings). The risk of not protesting is a tenant claim for the full excess amount — potentially for multiple years.

When Protesting Is Not Worth It

Not every assessment warrants a protest. The effort is not justified when:

  • The assessment is at or below market value
  • The potential reduction is less than $2,000–$3,000 (the cost of the effort exceeds the savings)
  • The jurisdiction has a "no decrease" rule that locks in the current value as a floor for future years
  • A recent sale established the value, and the assessment matches the sale price

Property Tax Protests Across Key Markets

Protest procedures, timelines, and success rates vary significantly by jurisdiction.

MarketFiling DeadlineTypical ResolutionAverage Reduction (when successful)
Harris County, TXMay 15 (or 30 days from notice)6–12 months10–20% of assessed value
Dallas County, TXMay 156–12 months8–15%
Cook County, IL30 days from publication12–24 months10–25%
Los Angeles County, CASeptember 1512–18 months5–15%
Maricopa County, AZWithin assessment cycle6–12 months5–12%
King County, WAJuly 16–12 months5–10%

Texas and Illinois tend to produce the largest reductions because their assessment processes are more aggressive and their protest mechanisms are more accessible. California reductions are smaller but still meaningful on high-value properties.

Building a Tax Protest Workflow into CAM Reconciliation

Annual Process

  1. January–February: Review assessment notices as they arrive. Compare assessed values to recent comparable sales and internal valuations.

  2. March–April: Engage tax consultants for properties where the assessment exceeds estimated market value by more than 5%.

  3. May–June: File protests. Document the filing for each property — date, assessed value, target value, consultant engaged.

  4. Year-end: For the annual reconciliation, note which properties have pending protests. Include the full tax payment in the reconciliation with a notation that a protest is pending.

  5. When refund arrives: Calculate tenant-by-tenant allocation. Issue credits or supplemental statements within 60 days of receiving the refund.

Documentation Requirements

For each tax protest, maintain:

  • A copy of the protest filing
  • The original assessment notice
  • Comparable sales data supporting the protest
  • Settlement documents or hearing results
  • Refund calculation showing tenant-by-tenant allocation
  • Proof of credit or payment to each tenant

This documentation package serves double duty: it supports the protest itself and it defends the CAM billing if a tenant auditor questions the tax charges.

How CapVeri Handles Tax Protest Adjustments

Tax protest refunds are one of the most error-prone adjustments in CAM reconciliation because they span multiple periods and require retroactive allocation. CapVeri tracks pending protests at the property level, automatically calculates the tenant-by-tenant allocation when a refund amount is entered, and generates the supplemental credit statement — including the pro-rata share math that an auditor can verify.

The calculation is deterministic: the same refund amount, applied to the same tenant roster and pro-rata shares, produces the same credits every time. No manual spreadsheet allocation, no rounding errors, no tenants accidentally left off the distribution.
