OFFICE TAX ASSESSMENT OVERVIEW
Understanding Office Property Tax Assessments
Office properties are assessed primarily through the income approach, which converts net operating income into a value indication by applying a capitalization rate. Assessors also rely on the sales comparison approach, using transactions involving comparable office buildings, and occasionally the cost approach for owner-occupied or newer construction. The core challenge is that assessment methods used in Michigan, Indiana, and Ohio were largely calibrated to pre-pandemic office markets — markets that no longer exist in the same form.
Remote and hybrid work arrangements have pushed office vacancy to generational highs in many submarkets, while sublease availability has suppressed effective rental rates well below asking rents. Class B and C office buildings face an additional layer of pressure as tenants consolidate into higher-quality space, leaving older stock functionally obsolete for much of the tenant pool. Strategies for reducing property taxes on office assets center on demonstrating actual vacancy, documenting below-market lease renewal terms, and applying cap rates that reflect current investor expectations — which have expanded materially as office risk has increased. Learn more about how cap rates affect commercial property tax assessments. EPTA offers a free review to determine whether your office assessment reflects these realities.
Actual vacancy and sublease availability versus assessor’s stabilized occupancy
Expanded market cap rates not reflected in the assessor’s income model
Functional obsolescence for Class B/C buildings losing tenants to newer stock
Below-market lease renewals and tenant improvement concessions as evidence of value decline
Our team has handled office appeals for banking institutions, real estate syndicates, and private investors across Michigan, Indiana, and Ohio. Request a free review and we will identify whether your current assessment overstates the market value of your property.


OFFICE TAX CHALLENGES
Why Office Properties Are Frequently Over-Assessed
Remote Work Driving Vacancy Up
Post-pandemic vacancy rates have surged, but assessments haven't adjusted.
Sublease Space Not Reflected
Available sublease space depresses effective rental rates, yet assessors ignore it.
Class B/C Obsolescence
Older office buildings lose tenants to newer stock, but assessed values don't reflect the gap.
Cap Rate Compression Ignored
Market cap rates for office have expanded, but assessments still use outdated rates.

WHY OFFICE OWNERS TRUST EPTA
Deep Experience with Office Property Appeals
Whether you own a single-tenant office building or a multi-tenant office park, we understand the valuation complexities that lead to over-assessment — and how to challenge them with precision. Our team applies income analysis, cap rate research, and market rental data to build arguments that reflect the real state of the office market rather than the assumptions assessors carried over from better years. We operate across Michigan, Indiana, and Ohio, and most of our cases reach resolution through negotiation rather than formal hearings. What our clients say is that they appreciated a process that required minimal time on their part while delivering meaningful, documented reductions in their annual tax obligations.
Office buildings are primarily assessed using the income approach, which considers rental income, vacancy rates, operating expenses, and capitalization rates. Assessors may also use the sales comparison or cost approach. Over-assessments commonly occur when assessors use pre-pandemic lease rates, ignore rising vacancy, or apply cap rates that don't reflect current investor expectations for office properties. The gap between pre-pandemic assessment assumptions and today's office market fundamentals is often substantial, and that gap represents real money on your tax bill. Our team examines the specific inputs in your assessment — lease rates, vacancy, cap rates — and quantifies the divergence from current market evidence.
The shift to remote and hybrid work has driven up office vacancy rates and depressed rental demand in many markets. However, many assessors have not adjusted their valuations to reflect this new reality. If your office building's assessment still reflects pre-pandemic occupancy and rental assumptions, you likely have strong grounds for an appeal. The impact is not uniform: suburban markets have fared differently from urban cores, and Class A properties have retained more demand than older Class B and C buildings. Understanding where your specific property sits in that landscape is critical to building an effective appeal.
Yes. Office property owners have the right to appeal their assessments in every state where EPTA operates. Whether you own a single-tenant office building or a multi-tenant office park, you can challenge the assessed value if it exceeds fair market value. Start with a free assessment review. Each state has specific deadlines for filing appeals, and missing them forfeits your right to challenge that year's assessment — so early engagement matters. Our team will confirm your applicable deadlines as part of the free review process.
A capitalization rate (cap rate) converts a property's net operating income into an estimate of value. Office cap rates have expanded in many markets due to increased risk and reduced demand, which means values should be lower. But assessors often use outdated or compressed cap rates that inflate assessed values. Learn more about cap rates and property taxes. In the current office market, demonstrating that an assessor used a cap rate two or three hundred basis points below what the market requires can produce a substantial downward adjustment to assessed value. This analysis is a central part of how our team approaches office appeals. Our cap rate and property tax resource explains the methodology in detail.
Savings depend on the size of the building, the degree of over-assessment, and local market conditions. Office property owners routinely see meaningful reductions in their annual tax bills. There's no cost to find out — request a free review to see if your property qualifies. Our office clients have included banking institutions and multi-property syndicates that have achieved six-figure annual savings across Michigan, Indiana, and Ohio. The potential reduction is directly tied to how much the current assessment overstates market value — which a free review will help establish. Read what our clients have experienced.
EPTA handles office property tax appeals in Michigan, Indiana, and Ohio. In Michigan, office property appeals are filed with the Michigan Tax Tribunal, with petition deadlines typically falling on May 31 or July 31. In Indiana, the appeal process runs through the county Property Tax Assessment Board of Appeals (PTABOA), with further review available before the Indiana Board of Tax Review (IBTR). In Ohio, appeals are filed with the county Board of Revision by March 31 of the relevant year. Each state has distinct procedural requirements, documentation standards, and negotiation dynamics, and our team manages the process from beginning to end in all three jurisdictions so you can focus on your property and business. For state-specific deadline information, see our property tax appeal deadlines resource.
While specific outcomes vary by property, market, and the strength of available evidence, office property tax appeals have a strong track record when they are built on well-documented income, expense, and market data. The office sector's current fundamentals — elevated vacancy, compressed rents, and expanded cap rates — provide genuine valuation support that was not available in prior market cycles. Our team screens each property before accepting an engagement, which means we pursue appeals where the evidence supports a reduction. Most of our office cases are resolved through negotiated settlement, which generally produces faster results and avoids the uncertainty of a formal hearing. The first step is a free review to assess whether your property's assessed value diverges meaningfully from market evidence. You can also read about what determines appeal success rates before getting started.
EPTA works on a contingency basis for office property tax appeals, meaning there is no upfront cost and no fee unless we achieve a reduction in your assessment. Our fee is calculated as a percentage of the actual tax savings you receive — so our interests are directly aligned with yours. There are no hourly charges, no filing fees passed through to you, and no retainers required to get started. We handle all aspects of the appeal, including the initial review, evidence gathering, negotiations with the assessor's office, and formal hearing preparation if needed. This structure allows office property owners to pursue appeals without financial risk, which is particularly valuable given the scale of potential savings on larger office buildings.
