What's New(p2)

Form 1099-INT.(p2)
A new box 13 has been added to Form 1099-INT to report bond premium on tax-exempt bonds. All later boxes were renumbered. For a tax-exempt covered security acquired at a premium, box 13 shows the amount of bond premium amortization allocable to the interest paid during the tax year. If a net amount of interest appears in box 8 or 9, whichever is applicable, box 13 should be blank.


Net investment income tax (NIIT).(p2)
Beginning in 2013, you may be subject to the NIIT. The NIIT applies at a rate of 3.8% to certain net investment income of individuals, estates, and trusts that have income above statutory threshold amounts. See Net investment income tax (NIIT), later.
Mutual fund distributions.(p2)
Pub. 564, Mutual Fund Distributions, has been incorporated into this publication.
Foreign source income.(p2)
If you are a U.S. citizen with investment income from sources outside the United States (foreign income), you must report that income on your tax return unless it is exempt by U.S. law. This is true whether you reside inside or outside the United States and whether or not you receive a Form 1099 from the foreign payer.
Employee stock options.(p2)
If you received an option to buy or sell stock or other property as payment for your services, see Pub. 525, Taxable and Nontaxable Income, for the special tax rules that apply.
Photographs of missing children.(p2)
The Internal Revenue Service is a proud partner with the National Center for Missing and Exploited Children. Photographs of missing children selected by the Center may appear in this publication on pages that would otherwise be blank. You can help bring these children home by looking at the photographs and calling 1-800-THE-LOST (1-800-843-5678) if you recognize a child.
