Why are dividends NOT counted as income under the equity method?

You are right that dividends are real cash coming in. The accounting treatment is counterintuitive because the equity method is designed to avoid double-counting the investor's share of the investee's earnings.

Here is the logic in three steps:

Step 1 — When the investee earns money, the investor picks up its share immediately.

If William Inc. earns $300,000 and Lucia owns 30%, Lucia records $90,000 of "equity income" on its income statement and adds $90,000 to its investment balance — even though no cash has changed hands. The economic value of Lucia's investment grew by $90,000 because the equity it owns grew.

Step 2 — When the investee pays a dividend, that's a return of capital.

A dividend is the investee paying out cash that came from the earnings the investor already recognised. If Lucia were to also treat the dividend as income, it would count the same earnings twice — once when the investee earned the money, once when it paid it out.

Step 3 — So dividends reduce the investment carrying value:

Compare to fair-value method (under 20% ownership):

If Lucia owned only 5% of William, the fair-value (or available-for-sale) accounting would be different:

• Dividends ARE income to the investor (because you only see the cash, not the earnings)
• Earnings flow through fair-value changes in the share price

So the rules are mode-dependent: significant influence = equity method = dividends are return of capital. Below significant influence = fair value = dividends are income.

Tax wrinkle:

For US tax purposes (relevant to CPA and EA candidates), dividends received by a corporation from a US investee qualify for the dividends-received deduction (DRD) at 50%, 65%, or 100% depending on ownership %. This is separate from the GAAP accounting and can produce a tax-versus-book difference reported in the tax footnote. Don't confuse the financial-statement treatment with the tax treatment.

Key takeaway:

Under the equity method, the investor's P&L impact comes from the investee's NET INCOME (share of), not from the investee's DIVIDENDS. Dividends are cash flow, not income.
