Internal Revenue Service (U.S. Taxes)

Filing U.S. Taxes

US citizens must report their worldwide income on their federal income tax returns. Living or earning income outside the United States does not relieve a US citizen of the responsibility of filing tax returns. However, US citizens living and/or working abroad may be entitled to various deductions, exclusions, and credits. ACS provides a limited supply of federal tax forms. No state forms are provided. For more information on US tax issues overseas, please consult the Internal Revenue Service, at their web site:

The IRS no longer automatically mails individual or business tax packages. 

The IRS is taking this step due to a substantial increase in the number of American citizens filing electronically, as well as a way to reduce printing costs and environmental impact. All current IRS forms, instructions, and publications can be found and printed from your computer here: Or, if you would like copies of the forms mailed to you, all forms, instructions, and publications can be ordered by phone at +1 (800) 829-3676, or online here:

As such, the IRS offers multiple options for addressing previous failures to comply with U.S. tax and information return obligations.
