Tax Treatment of Investment Products

Now that you know the underlying securities, you can see how the tax code handles the income they produce. The unifying concept is the pipeline (also called conduit) theory under Internal Revenue Code Subchapter M: a regulated investment company passes income through to shareholders without paying tax at the fund level.

How does Subchapter M conduit theory work?

Under Internal Revenue Code Subchapter M, a regulated investment company (mutual fund, closed-end fund, UIT, ETF) is a pass-through entity for tax purposes.

• Income and realized gains distributed to shareholders are taxed to the shareholders, not to the fund
• To qualify, the fund must distribute at least 90% of its net investment income to shareholders
• The fund acts as a conduit or pipeline: earnings flow through to investors without a corporate-level tax layer
• Distributions retain their character:
  • Taxable interest income passes through as ordinary income
  • Qualified dividends retain preferential Long-Term Capital Gain (LTCG) rates
  • Long-term capital gains retain LTCG rates

Think of it this way: A regular corporation pays corporate tax on its profits, then shareholders pay dividend tax on what is left. That is double taxation. A Subchapter M fund skips the corporate layer entirely. The tradeoff: the fund must distribute nearly everything it earns, which is why mutual funds send out 1099s every year.

Exam Tip: Gotchas

• The magic distribution threshold is 90% of net investment income, not 100%. Most funds distribute 98-99% in practice to avoid a 4% federal excise tax, but the Subchapter M qualification line is 90%.
• Distributions keep their character. A fund cannot convert non-qualified income into qualified dividends. What goes in determines what comes out.

How are capital gains and losses taxed?

Capital gains occur when a security is sold for more than its cost basis. The tax rate depends on how long the security was held.

Netting capital gains and losses (in order):

1. Net short-term gains and losses against each other
2. Net long-term gains and losses against each other
3. Net the two remaining totals together

Excess loss deduction:

• Up to $3,000 per year deducts against ordinary income
• $1,500 for married filing separately
• Unused losses carry forward indefinitely to future tax years

Exam Tip: Gotchas

• Net within holding period first, then across. The two-step netting is a common exam trap: you cannot skip to the total.
• Only $3,000 of net capital loss deducts against ordinary income per year. The remainder carries forward indefinitely; the carryforward retains its short-term or long-term character.

What is the difference between qualified and non-qualified dividends?

Not all dividends are taxed the same. The qualified dividend label unlocks preferential LTCG rates.

Holding-period test for qualified dividends (common stock):

• Hold the stock for more than 60 days during the 121-day window that begins 60 days before the ex-dividend date

Payments that generally do not receive qualified-dividend rates:

• Most Real Estate Investment Trust (REIT) dividends, which are taxed at ordinary income rates. A REIT can designate part of a distribution as a capital gain dividend, which the shareholder treats as long-term capital gain, or, in limited amounts, as a qualified dividend (for example, dividends the REIT itself received from a taxable corporation)
• Taxable interest-derived distributions from money market funds
• Substitute payments received in place of dividends while stock is on loan. The Internal Revenue Service treats these payments as other income rather than as dividends or interest

Pass-through principle:

• A fund cannot convert non-qualified income into qualified dividends
• Fund distributions pass through the character of the underlying source

Exam Tip: Gotchas

• Taxable interest-derived money market fund dividends are not qualified dividends. Money market funds hold short-term debt, so taxable interest passed through to shareholders remains ordinary dividend income.
• Most REIT dividends are not qualified dividends. A REIT may separately designate a capital gain dividend or a limited qualified-dividend component, so read the distribution's reported tax character rather than relying on the product label alone.

What is the wash sale rule?

The Internal Revenue Code disallows a capital loss if the same (or substantially identical) security is repurchased within a short window around the sale.

• 61-day total window: 30 days before the sale + day of sale + 30 days after the sale
• Taxable replacement account: the disallowed loss is added to the replacement security's cost basis
• Holding period carries over: the replacement share inherits the original holding period
• The rule applies across accounts the taxpayer controls, including accounts belonging to a spouse or controlled corporation
• Applies to mutual fund share purchases the same way: buying into a substantially identical fund triggers the rule

Think of it this way: When the replacement is bought in a taxable account, the disallowed loss is baked into the new shares' cost basis. On a later sale outside the wash-sale window, that basis adjustment produces a larger capital loss (or smaller gain). A replacement bought in an IRA gets no such adjustment, so that loss is permanently unavailable for tax purposes.

Exam Tip: Gotchas

• The wash sale window is 61 days total: 30 before + day of + 30 after. Selling at a loss on December 15 and rebuying on December 28 triggers the rule even though both trades are in the same tax year.
• A taxable replacement purchase defers the loss. The disallowed loss increases the replacement share's cost basis, and the original holding period carries over.
• An Individual Retirement Account (IRA) replacement purchase permanently loses the tax benefit. The wash-sale loss is disallowed, but no adjustment is made to the IRA shares' basis.

How are holding periods determined for tax purposes?

The holding period determines short-term vs. long-term treatment.

• Holding period begins the day after the trade date (acquisition)
• Holding period ends on the trade date (disposition)
• Inherited securities: automatically long-term regardless of how long the decedent held them
• Gifted securities: donor's holding period carries over to the donee (along with the donor's cost basis for gain calculations)

Exam Tip: Gotchas

• Inherited securities are always long-term. This pairs with the step-up in cost basis to date of death (or alternate valuation date) to make inherited stock especially tax-favored.
• Gifted securities carry over the donor's holding period. A gift of stock the donor held 10 months becomes long-term only after an additional 2+ months in the donee's hands.

What Should You Check on Exam Day?

• Do you know a regulated investment company must distribute at least 90% of net investment income to shareholders under Subchapter M?
• Can you state the netting order for capital gains and losses: short-term against short-term, long-term against long-term, then combine the totals?
• Can you distinguish taxable interest-derived money market distributions and most REIT dividends from separately reported components with a different tax character?
• Can you explain the wash-sale rule's 61-day window and distinguish a taxable replacement purchase (basis adjustment) from an IRA replacement purchase (no basis adjustment)?
• Do you know inherited securities are always treated as long-term, while gifted securities carry over the donor's holding period?
