Washington D.C. Tax Administration Framework

The tax administration framework in Washington D.C. governs how individuals and businesses comply with local tax laws. Although not centralized under one single statute, D.C.’s tax obligations are established through Title 47 of the D.C. Official Code and administered by the Office of Tax and Revenue (OTR). This article outlines how taxes are assessed, filed, enforced, and disputed under the current D.C. system.

  • Include all supporting documentation

 

Deadlines vary by tax type but commonly range from 20 to 45 days after the end of the tax period.



Washington D.C. Tax Administration Framework: Assessment Notices


The OTR issues formal Notices of Proposed Assessment when:

  • A return is not filed

Taxpayers have 30 days from the notice date to respond, request an informal review, or initiate formal appeals.

Washington D.C. enforces a structured penalty system for late or inaccurate tax filings.

  • Underreporting Penalty: 20% of the underreported amount
  • Fraud Penalty: 75% of the tax due if fraud is proven


Washington D.C. Tax Administration Framework: Interest Charges

An informal protest may be submitted to the OTR within 30 days of the assessment notice. The taxpayer may include documentation, legal arguments, and payment proposals.



Washington D.C. Tax Administration Framework: Office of Administrative Hearings (OAH)


If the informal review is denied, taxpayers may file an appeal with the OAH. This independent body has the authority to:

  • Uphold, reverse, or modify assessments
  • Conduct hearings with testimony and evidence

Washington D.C. Tax Administration Framework: Superior Court Review


Taxpayers may also seek judicial review through the D.C. Superior Court following OAH decisions or in complex disputes involving constitutional claims.

Amended returns are allowed to correct previously filed returns. They must be clearly marked and follow the same format as original filings.

The OTR conducts audits to ensure tax compliance, often based on random selection or suspicion of underreporting.

  • Desk Audit: Conducted remotely using documents submitted by the taxpayer
  • Field Audit: Conducted on-site at the taxpayer’s location
  • Special Audit: Triggered by red flags or referral from another agency
