Contact

Reaching the right office with a well-prepared inquiry reduces resolution time and ensures the question is routed to the correct bureau or division. This page explains what information to include in a message, what response timelines to expect, how different contact channels compare, and which offices handle specific types of Treasury-related inquiries.

What to include in your message

A complete, specific inquiry moves faster through any government or institutional intake process than a vague one. Before submitting a message, gather the following elements:

1. Full legal name and contact information — the name as it appears on any relevant account, filing, or government record, plus a reply email address or phone number.
2. Subject matter category — identify whether the inquiry concerns tax policy, debt instruments such as Treasury securities or savings bonds, sanctions programs, unclaimed assets, or another specific function.
3. Relevant identifying numbers — for tax matters, a Taxpayer Identification Number (TIN) or Employer Identification Number (EIN) may be required; for TreasuryDirect account issues, the account number is essential.
4. A clear, specific question — a single direct question receives a faster and more accurate response than an open-ended general inquiry. Where applicable, cite the specific program, regulation, or bureau involved.
5. Supporting documentation references — if the inquiry relates to a specific notice, letter, or transaction, include the date and document reference number rather than a general description.

Inquiries that omit identifying information or fail to specify a bureau — such as the Bureau of the Fiscal Service, the Office of the Comptroller of the Currency, or the Financial Crimes Enforcement Network — are likely to be redirected, adding days or weeks to response time.

Response expectations

Response timelines vary significantly depending on the bureau, the complexity of the inquiry, and whether the question requires a legal or policy review.

Routine informational inquiries — questions about publicly available data such as the Daily Treasury Statement, interest rates on savings bonds, or TreasuryDirect account procedures — are typically addressed within 3 to 10 business days through standard channels.

Regulatory or compliance inquiries — questions directed at the Office of Foreign Assets Control regarding sanctions licenses, or at FinCEN regarding Bank Secrecy Act obligations — may take 30 to 90 days depending on case volume and the need for legal review.

Congressional or formal agency correspondence — written inquiries submitted through a congressional representative's office or via formal agency letter may receive priority routing and a written response within statutory or policy-defined windows.

The distinction between an informational inquiry and a regulatory request matters: informational questions ask what a policy says; regulatory requests ask for an official determination, license, or ruling that carries legal weight. The latter requires significantly more documentation and review time.

Additional contact options

The U.S. Department of the Treasury and its bureaus maintain bureau-specific contact channels that are more precise than a general department-level inquiry form.

• IRS matters: The Internal Revenue Service maintains a dedicated taxpayer contact infrastructure at irs.gov, including the Taxpayer Assistance Center (TAC) network with over 360 walk-in locations across all 50 states. Tax-related questions fall outside Treasury's general inquiry scope and should be directed to the IRS directly.
• TreasuryDirect and savings bonds: The Bureau of the Fiscal Service operates TreasuryDirect at treasurydirect.gov, with a dedicated customer service line and online help center for account and redemption questions.
• Currency and coin: The Bureau of Engraving and Printing and the U.S. Mint each maintain separate public contact pages for inquiries about currency production, collectible coins, and facility tours.
• CFIUS inquiries: Questions regarding foreign investment review under the Committee on Foreign Investment in the United States should be directed through the formal CFIUS submission process described at treasury.gov/resource-center/international/foreign-investment, given that informal inquiries about specific transactions are not processed outside official channels.
• Sanctions and OFAC: The Office of Foreign Assets Control provides a dedicated contact page for sanctions-related questions, license applications, and compliance guidance at ofac.treas.gov.

How to reach this office

The U.S. Department of the Treasury headquarters is located at 1500 Pennsylvania Avenue NW, Washington, D.C. 20220. The main public inquiry line is (202) 622-2000. The department's official public-facing contact portal is available at treasury.gov/about/contact-us.

For press and media inquiries, the Office of Public Affairs handles requests separately from public inquiries and can be reached through the media contact portal at treasury.gov.

Written correspondence addressed to the Secretary of the Treasury should include a complete return address and a clearly stated subject line identifying the relevant bureau or program area. Correspondence without a subject identification is processed through general mail handling, which adds a minimum of 15 business days to initial routing.

For matters involving the Inspector General for Tax Administration, a separate reporting channel exists through the TIGTA hotline at 1-800-366-4484, which handles complaints about IRS employee conduct and tax administration issues independently from Treasury's main contact infrastructure.
