IRS Tax Information
The American Citizen Services unit no longer receives from the Internal Revenue Service (IRS) forms and publications. Individuals who are required to make federal income tax declarations may obtain these forms on the IRS Internet website at www.irs.gov.
Consular officers at the American Citizen Services unit can notarize documentation to accompany the application (Form W-7) that non-U.S. citizens must submit to obtain a Taxpayer Identification Number (TIN). The fee for this notarial service is USD 30.
Consular officers also can certify photocopies of documents requested by the IRS if the originals of these documents are brought to the American Citizen Services unit between 8:15 and 11:30 a.m. any workday, with the exception of American and Salvadoran holidays, and the first Wednesday of each month. Since the IRS has requested copies of these documents, no fee is charged for these certifications.
Unfortunately, the IRS currently does not send an official to El Salvador to provide federal tax assistance. The staff of the American Citizen Services unit is not trained or authorized to provide federal tax advice.
Both forms and information are available from the IRS through the following links:
