Property Tax Appeal and CAM: What Happens to Your Recovery When You Win
A successful property tax appeal is good news for cash flow. But it immediately creates a CAM accounting problem that most landlords aren't prepared for: the taxes that were already passed through to tenants need to come back.
The mechanics are straightforward in concept but require careful execution: the refund reduces your net property tax expense for the applicable year, and tenants who paid CAM including those taxes are entitled to their pro-rata share of the reduction. How that flows through your CAM pool and reconciliation depends on lease language, timing, and whether you've already issued the year's reconciliation statements.
The Problem: You Won the Appeal — Now What?
When a property tax appeal is filed, it typically covers one or more prior assessment years. The assessment authority reviews the appeal, and if successful, issues a corrected tax bill and often a refund for any taxes already paid above the corrected assessment.
During this period, your CAM pool has been including the full (pre-appeal) property tax amount. Tenants have been paying CAM based on those higher figures. When the appeal succeeds and the refund arrives, you've effectively over-collected property tax CAM from tenants.
The legal and ethical obligation is clear: the over-collected amount must be returned to tenants in some form. The practical question is how.
How Tax Refunds Flow Through CAM Pools
The refund reduces the net property tax expense in your CAM pool. If the pool included $500,000 in property taxes for the appeal year, and you receive a $75,000 refund, the net property tax expense for that year was actually $425,000.
This creates a retroactive CAM credit for tenants: each tenant's pro-rata share of the $75,000 refund represents an amount they overpaid.
The credit calculation:
- Total refund: $75,000
- Tenant's pro-rata share: 8% (their SF / total pool SF)
- Tenant's credit: $75,000 × 8% = $6,000
If the year's reconciliation has already been issued and settled, you'll need to issue an amended statement or a separate credit memo reflecting the refund.
If the year's reconciliation hasn't been issued yet, simply reduce the property tax line in the pool by the refund amount before finalizing the reconciliation. Much simpler.
Year of Appeal vs. Year of Refund
Property tax appeals routinely span multiple years, and refunds may arrive years after the appealed assessment period. This timing mismatch creates a specific accounting question: do you recognize the refund in the year the taxes were originally charged (the appeal year), or in the year the refund is received?
Most commercial leases address this in the property tax provisions. Common approaches:
Recognition in the appeal year. Issue amended reconciliation statements for each year in which taxes were over-charged. This is most accurate but requires re-opening prior-year reconciliations, which may already be final under the lease's audit limitation period.
Recognition in the refund year. Treat the refund as a reduction to the current year's property tax expense (or as a negative line item in the current year's pool). Tenants occupying during the refund year receive the credit, not necessarily the tenants who paid during the appeal years.
The refund-year treatment is administratively simpler but is technically less accurate — tenants who occupied during the appeal years but have since vacated receive no benefit, and current tenants receive a credit for taxes they didn't pay.
Check your specific lease provisions. If the lease is silent, consult with your attorney before deciding — the choice has legal consequences.
Amended Reconciliation Statements
If your approach requires amending prior-year reconciliation statements:
- Calculate the corrected pool total for each affected year — replace the original tax amount with the tax-minus-refund amount
- Recalculate each tenant's pro-rata share of the corrected pool
- Compare against estimated and actual amounts previously billed and settled
- Issue credit memos to each current tenant for their share of the difference
- For tenants who have vacated: issue credit checks or apply credits per the lease terms; do not ignore vacated tenants who have amounts owed to them
Amended statements should clearly explain the reason for the amendment (property tax appeal settlement), the years affected, and the calculation of each tenant's credit.
Lease Language on Tax Refunds
Not all leases address tax refunds explicitly. The variations:
Explicit pass-through provision: "If Landlord receives a refund of real property taxes attributable to any period during the Lease Term, Tenant's pro-rata share of such refund shall be credited against future CAM obligations or paid directly to Tenant."
Net tax approach: Some leases define property taxes as net of any refunds, credits, or abatements received — meaning the refund automatically reduces the tax amount in the pool.
Silent on the issue: When the lease is silent, the general principle is that tenants who paid for an expense that was subsequently refunded are entitled to their share of the refund. Courts have generally supported this position.
If your lease is silent and you're uncertain how to proceed, consult with a commercial real estate attorney before deciding on a treatment.
Tenant Notification and Credit Process
Once you've calculated the credit amounts, the notification process:
- Send a written notice explaining the property tax appeal result, the refund received, and the calculation of each tenant's credit
- Provide supporting documentation — the original assessment, the appeal determination, and the refund amount
- Specify how the credit will be applied — against upcoming CAM estimates, against year-end reconciliation, or as a direct payment
- Document the credit in your tenant ledger — create a clear paper trail showing the credit was properly calculated and applied
Proactive, transparent notification prevents tenants from discovering the appeal on their own (through public records) and questioning why they weren't notified.
Future Year Estimate Adjustments
A successful tax appeal changes your property tax baseline. For the years following the appeal, your CAM estimates should be based on the corrected (lower) assessed value, not the pre-appeal assessment.
Update your CAM budget and tenant estimate amounts to reflect the corrected assessment. If your ERP has a property tax line in the CAM estimate calculation, update that figure for the next budget cycle.
Failure to update estimates after a successful appeal results in tenants continuing to pay estimates based on the higher assessment — creating an over-collection problem that, when discovered, requires retroactive credits.
Documentation Requirements for Auditors
Maintain a complete property tax appeal file that includes:
- Original assessment notice
- Appeal filing documents
- All correspondence with the assessment authority
- Appeal determination and corrected assessment
- Refund documentation (check, EFT confirmation)
- Your CAM credit calculation methodology
- Amended reconciliation statements or credit memos issued
- Tenant notification letters and delivery confirmation
This file should be retained for the full audit window (typically 3+ years from each reconciliation statement) to support tenant audit requests.
