The 3.8 percent surtax on investment income, meant to help pay for healthcare, goes into effect in 2013. It is the first surtax to be applied to capital gains and dividend income.

The tax affects only individuals with more than $200,000 in modified adjusted gross income (MAGI), and married couples filing jointly with more than $250,000 of MAGI.

The tax applies to a broad range of investment securities ranging fromstocks and bonds to commodity securities and specialized derivatives.

The 159 pages of rules spell out when the tax applies to trusts and annuities, as well as to individual securities traders.

Released late on Friday, the new regulations include a 0.9 percent healthcare tax on wages for high-income individuals.

Both sets of rules will be published on Wednesday in the Federal Register.

The proposed rules are effective starting January 1. Before making the rules final, the IRS will take public comments and hold hearings in April.
