Investment Income Tax Guide
Investment income is not one tax category.
Interest can be ordinary or federally exempt. Dividends can be ordinary or receive preferential rates. A bond can create taxable income before it pays cash. Foreign withholding can create a credit problem. Investment borrowing can produce a deduction—or fail to.
And several of those items can also trigger the 3.8% Net Investment Income Tax.
The useful question is therefore not simply:
How much investment income did I receive?
It is:
What kind of income is it, when is it recognized, what rate system applies, and what other tax rules sit on top of it?
This section of the PRISM Investment Tax Atlas separates those questions so one classification is not mistaken for another.
Topics in this section
Qualified vs. Ordinary Dividends
Understand why some dividends receive preferential federal rates while others remain subject to ordinary income-tax rates.
Mutual Fund and ETF Distributions
Separate ordinary dividends, qualified dividends, capital-gain distributions, exempt-interest dividends, and nondividend distributions.
Treasury Interest
Understand why direct Treasury interest is generally taxable federally but exempt from state and local income taxation—and why Treasury funds require separate analysis.
Municipal Bond Interest
See what “tax-free” actually covers, including market discount, bond premium, AMT, sale gains, and state treatment.
Original Issue Discount
Understand why OID can create taxable interest before the investor receives corresponding cash.
Where this becomes a professional question
Investment-income analysis becomes more consequential when several regimes overlap—for example, large portfolios, NIIT exposure, foreign withholding, bond premium or discount, substantial margin debt, multi-year carryforwards, or multi-state taxation.
In those situations, the useful analysis is usually not a single tax rate. It is a whole-return model showing how character, timing, deductions, credits, surtaxes, and state rules interact.
