District of Columbia Commercial Property Tax Appeals
Office, retail, industrial, multifamily, and special-purpose buildings in District of Columbia are frequently over-assessed. Here's how commercial assessments work, the deadline to challenge yours, and what it takes to win.
How commercial is assessed
The District assesses at 100% of market value and taxes commercial (Class 2) at higher rates than residential, with a top tier for high-value commercial. Income-producing property files an annual income-and-expense report.
Commercial (Class 2) taxed above residential, with a higher tier for high-value property.
Burden of proof
The property owner (or their authorized agent) bears the burden of proving the assessment exceeds market value. The assessor's value is presumed correct until rebutted with credible evidence.
Key to a District of Columbia commercial appeal: Two-level appeal + mandatory I&E
First-level review with OTR by April 1, then the Real Property Tax Appeals Commission. Income-producing commercial must file the income-and-expense report, which drives the assessor's income approach.

How commercial value is proven
Income-producing commercial property is usually valued by capitalizing net operating income (NOI ÷ market cap rate). The strongest appeals come with a clean rent roll, a trailing-12-month operating statement, current vacancy, and market cap-rate support. Where the property is owner-occupied or special-purpose, the cost and sales-comparison approaches carry more weight.
Evidence that wins a commercial appeal
- Current rent roll and a trailing-12-month operating statement
- Actual vacancy and collection loss (vs the assessor's stabilized assumption)
- Market capitalization rate support for the property type and submarket
- Recent arm's-length sales of comparable commercial buildings
- Evidence of physical, functional, or economic obsolescence
- Any change in use, tenancy, or condition since the assessment date
How to appeal a commercial assessment in District of Columbia
- 1Pull the assessment — confirm the assessed value, the assessment ratio/class, and how the assessor derived it (income, cost, or sales).
- 2Build the valuation — capitalize actual net operating income and gather comparable sales to establish market value as of the assessment date.
- 3File before the deadline — submit to Office of Tax and Revenue (OTR) Real Property Tax Administration by April 1 (first level); October 1 (second level after tax bill), with the authorization signed by someone able to bind the owning entity.
- 4Present at the hearing — commercial hearings are evidence-driven; a clean income approach and credible comps carry the day.
