At the start of each year, commercial tenants receive their operating expense reconciliation statement for the prior year. This document shows the actual costs your landlord incurred to operate and maintain the property and it determines whether you owe additional funds or deserve a refund.
You should never treat this statement as a formality. A careful review can uncover billing errors, lease violations, and significant savings opportunities.
At National Lease Advisors, we review operating expense reconciliations for multi-location tenants nationwide. In 2024, we identified millions of dollars in billing discrepancies and recovered substantial overcharges for our clients.
Here’s how you can approach your 2025 reconciliation with confidence.
What is a 2025 Operating Expense Reconciliation?
Your lease fixes base rent. Operating expenses, however, fluctuate each year.
At the beginning of the year, landlords estimate operating costs and bill tenants monthly based on that estimate. After year-end, the landlord compares:
- Total estimated expenses billed
- Total actual expenses incurred
This comparison creates the annual operating expense reconciliation.
If actual costs exceed estimates, you owe a reconciliation payment.
If actual costs fall below estimates, the landlord must issue a credit or refund.
Because operating expenses include property taxes, insurance, utilities, maintenance, CAM, and management fees, even small errors can create large overcharges especially across multiple locations.
How Much Should Operating Expenses Increase in 2025?
Operating expense increases should reflect actual cost increases not assumptions.
Although inflation spiked in prior years, it has moderated. Certain categories, such as insurance and property taxes, remain elevated in some markets. However, landlords must still justify increases with real cost data.
If expenses rise significantly year-over-year, ask questions.
Watch for:
- Double-digit increases without documentation
- Administrative or management fees rising disproportionately
- Capital improvements charged as repairs
- New expense categories that your lease does not permit
Your lease defines what the landlord can recover not market headlines.
8 Steps to Review Your 2025 Operating Expense Reconciliation
1. Review the Math Immediately
Confirm:
- The reconciliation period
- Total estimated payments
- Total actual expenses
- Your pro rata share calculation
Math errors happen more often than most tenants realize.
2. Compare Charges to Your Lease
Your lease controls every charge.
Review:
- Expense exclusions
- Capital expenditure language
- Gross-up provisions
- Expense caps
- Base year calculations
- Audit deadlines
Many landlords charge items that the lease expressly excludes.
3. Analyze Year-Over-Year Variances
Pull prior reconciliations and compare trends.
Focus on:
- Repairs and maintenance spikes
- Utilities fluctuations
- Insurance increases
- Management fee percentages
Large variances demand explanations.
4. Validate Your Pro Rata Share
Confirm the building’s total rentable square footage and your suite size. Then verify the pro rata percentage calculation.
An incorrect denominator affects every expense category.
5. Request Supporting Documentation
Do not rely solely on summary reports.
Request:
- General ledger detail
- Vendor invoices
- Property tax bills
- Insurance declarations
- Management fee backup
Clear documentation supports accurate billing.
6. Scrutinize Capital Expenditures
Landlords often classify improvements as “repairs.”
Your lease may:
- Prohibit capital expenses
- Allow amortization only
- Require cost savings offsets
Read this section carefully, it often drives the largest disputes.
7. Engage a Lease Audit Professional
Operating expense audits require financial analysis and lease interpretation.
A qualified lease administration and audit team can:
- Identify non-compliant charges
- Validate gross-up calculations
- Recalculate management fees
- Quantify recoveries
- Protect audit rights and deadlines
For multi-location tenants, small errors per site quickly scale into material savings.
8. Submit Disputes Promptly
Most leases limit the time you have to dispute charges, often 90 to 180 days.
If you identify discrepancies:
- Submit a written notice
- Cite specific lease provisions
- Request corrections or reimbursement
Clear, documented communication drives faster resolution.
Why the 2025 Reconciliation Deserves Your Attention
Operating expenses directly impact occupancy cost, EBITDA, and financial reporting. Insurance volatility, tax reassessments, and rising service contracts continue to pressure tenants nationwide.
When you review your 2025 operating expense reconciliation proactively, you:
- Protect cash flow
- Improve forecasting accuracy
- Strengthen internal controls
- Support audit compliance
- Reduce long-term lease risk
Strong review processes create measurable financial returns.
Final Takeaway
Treat your 2025 operating expense reconciliation as a financial control opportunity.
By reviewing the statement carefully, validating charges against your lease, and requesting backup documentation, when necessary, you can ensure you are paying only what you owe and nothing more.
