Quick Answer
Investment returns split into return of capital (not taxable, reduces cost basis), tax-exempt municipal interest, taxable interest and dividends, and total return (income plus price change). Each has distinct tax treatment, and the tax-equivalent yield formula lets you compare a muni yield against a taxable alternative.
The Series 7 tests your ability to distinguish between these categories and apply the right tax rule to each, not just define them. Pay particular attention to which return types are taxable, which reduce cost basis instead, and how holding periods change the tax rate.
What Is Return of Capital?
- A distribution that is not from earnings or profits; it is a return of the investor's own investment
- Return of capital is not taxable when received
- Instead, it reduces the investor's cost basis in the security
- If cost basis is reduced to zero, any additional return of capital is taxed as a capital gain
- Common with: REITs, MLPs, some mutual funds (particularly those with distributions exceeding net income), and limited partnerships (DPPs)
- Disclosed on Form 1099-DIV in box 3 (nondividend distributions)
How cost basis reduction works:
| Step | Event | Cost Basis |
|---|---|---|
| 1 | Buy 100 shares at $50 | $5,000 |
| 2 | Receive $500 return of capital | $4,500 (reduced by $500) |
| 3 | Receive another $500 return of capital | $4,000 |
| ... | Continue receiving distributions | Keeps declining |
| N | Cost basis reaches $0 | $0 - any further return of capital is taxed as capital gain |
Exam Tip: Gotchas
- Return of capital is NOT income. It is the investor's own money coming back. When a distribution exceeds a fund's earnings and profits, the excess portion is return of capital, reducing cost basis.
- Once cost basis hits zero, return of capital becomes a capital gain. This catches students who assume return of capital is always tax-free.
What Makes Interest Tax-Exempt?
- Interest income that is excluded from federal income tax (and often state/local tax for in-state residents)
- Municipal bond interest is the primary source of tax-exempt interest
Key points:
- General obligation (GO) bonds and revenue bonds both pay tax-exempt interest at the federal level
- In-state advantage: interest from municipal bonds issued in the investor's home state is typically exempt from state and local taxes as well ("triple tax-exempt")
- Private activity bonds (certain municipal bonds financing non-governmental projects): interest may be a preference item for the alternative minimum tax (AMT)
- Tax-exempt interest is reported on tax returns (Form 1040) but is not included in taxable income
- Tax-exempt income is most beneficial for investors in high tax brackets
Tax-Equivalent Yield
This formula converts a tax-exempt yield to the equivalent taxable yield for comparison:
Tax-Equivalent Yield = Tax-Exempt Yield / (1 - Marginal Tax Rate)
| Municipal Yield | Tax Bracket | Calculation | Tax-Equivalent Yield |
|---|---|---|---|
| 4.00% | 32% | 4.00% / (1 - 0.32) = 4.00% / 0.68 | 5.88% |
| 3.50% | 35% | 3.50% / (1 - 0.35) = 3.50% / 0.65 | 5.38% |
| 3.00% | 24% | 3.00% / (1 - 0.24) = 3.00% / 0.76 | 3.95% |
Key point: The higher the tax bracket, the more attractive tax-exempt bonds become.
Exam Tip: Gotchas
- Tax-equivalent yield is a key calculation. Divide the municipal yield by (1 - tax rate), then compare the result to the taxable bond yield to determine which is more advantageous.
- Private activity bond interest may trigger AMT. Not all municipal bond interest is completely tax-free.
How Are Taxable Interest and Dividends Taxed?
Different types of investment income receive different tax treatment:
Interest Income
| Source | Federal Tax | State/Local Tax |
|---|---|---|
| Corporate bonds | Ordinary income | Yes |
| U.S. Treasury securities | Ordinary income | Exempt from state and local |
| Municipal bonds | Exempt (generally) | Exempt if in-state ("triple tax-exempt") |
Dividend Income
| Type | Tax Treatment | Requirements |
|---|---|---|
| Qualified dividends | Preferential long-term capital gains rates (0%, 15%, or 20%) | Must hold stock more than 60 days during the 121-day period around the ex-dividend date; must be paid by a U.S. corporation or qualified foreign corporation |
| Nonqualified (ordinary) dividends | Ordinary income rates | Does not meet holding period or issuer requirements |
Capital Gains
- Short-term (held 1 year or less): Taxed as ordinary income
- Long-term (held more than 1 year): Preferential rates (0%, 15%, or 20% depending on income)
Exam Tip: Gotchas
- Treasury interest is exempt from state/local tax, but NOT from federal tax. This is the opposite pattern from municipal bonds.
- Qualified dividends require a 60-day holding period during the 121-day window around the ex-dividend date to receive preferential capital gains rates. Miss the holding period and you pay ordinary income rates.
- Short-term capital gains (held 1 year or less) are taxed as ordinary income. The "or less" is key: selling on the one-year anniversary still counts as short-term.
How Do You Calculate Total Return?
- The complete measure of investment performance: income (interest, dividends) plus capital appreciation (or minus depreciation)
- Formula: (Income + Realized/Unrealized Gain or Loss) / Initial Investment
- Total return is the most comprehensive performance measure and is used for benchmark comparison
- Annualized return expresses total return on a per-year basis for comparing investments held over different time periods
Example:
- Buy a bond at $950, receive $60 in coupon payments, sell at $980
- Total return = ($60 + $30) / $950 = $90 / $950 = 9.47%
Exam Tip: Gotchas
- Total return includes BOTH income and capital gains/losses. A question asking for "total return" expects you to add coupon payments (or dividends) to any price change, then divide by the original investment.
- Unrealized gains count in total return. You do not need to sell the security for gains to be included in total return calculations.
What Should You Check on Exam Day?
- Return of capital is not income; it reduces cost basis, and once basis hits zero, any further distribution is a capital gain.
- Divide the municipal yield by (1 - tax rate) for tax-equivalent yield; private activity bond interest can still trigger AMT.
- Treasury interest is federally taxable but state/local exempt; municipal interest is the opposite.
- Short-term capital gains (held one year or less) are ordinary income; long-term gets preferential rates.
- Total return adds income to price change, including unrealized gains, over the original investment.
