The postal address for mailing a printed tax return is available on the IRS website, which provides several mailing addresses based on the type of return, if payments are included, and the type of mailing service used, the IRS explains. Addresses are also listed for government entities.
To find information on sending a federal tax return by mail, taxpayers can search on IRS.gov for addresses based upon the type of return being filed, the IRS notes. The address also differs when a taxpayer is submitting a tax payment with the form he is filing.
American taxpayers living outside the United States are provided with international addresses. Government organizations and tax-exempt entities can select a mailing address depending on the delivery service options they choose.
