Dividends explained: dates, yield, tax and what a payout really adds

A dividend is part of a company's profit paid to its shareholders, usually in cash and sometimes as extra shares. It feels like free money, but it isn't: on the day the share stops carrying the dividend, its price usually falls by about the same amount.

What matters is your total return: the price change plus the dividends, after tax and inflation. This guide shows how to read each part.

Where a dividend comes from

A company makes a profit. The board decides, or proposes to shareholders, how much of it to pay out. The rest stays in the business to fund growth or repay debt.

Nothing obliges a company to pay. A dividend can be raised, cut or skipped from one year to the next. Some companies pay once a year, others twice or every quarter. Listed companies announce each dividend through their stock exchange and on their investor relations pages.

The four dates that decide who gets paid

Trades take time to settle, so the ex-dividend date comes on or before the record date. The gap depends on your market's settlement time. Where trades settle in one business day, the two dates often fall on the same day. The rule that matters: own the share before the ex-dividend date.

Worked example: the price drop on the ex-date

These numbers are an example. You own 200 shares at $50, and the company pays $1.50 a share. Your country of residence, in this example, has 15% withheld.

Check: 9,700 + 255 = 9,955. The dividend moved $300 from inside the share to your account, and tax took $45. You only come out ahead if the business keeps earning and the price recovers over time.

Dividend yield and yield on cost

Dividend yield is the yearly dividend per share divided by today's price. If the company above pays $1.50 a year, that's $1.50 ÷ $50 = 3%.

Yield on cost divides the same dividend by the price you paid. Say you bought at $25 years ago. Your yield on cost is $1.50 ÷ $25 = 6%.

Yield on cost is pleasant to look at, but it doesn't help you decide. Your money is worth $50 a share today, and today it earns 3%. That's the figure to compare with a savings account or a fund.

For a sense of scale, the S&P 500 index yielded about 1.08% in September 2026, on trailing dividends of $83.09 a share (DQYDJ). Broad indexes in other markets can yield more or less.

Tax on dividends: it depends where you live and where the company is

Dividends are often taxed twice over: by the company's country, at source, and by your own country.

Withholding tax. Many countries withhold tax before the cash reaches you. The rate depends on the company's country, your residence and any tax treaty between them.

As an example, the US withholds 30% on dividends paid to foreign investors by default (IRS). Treaties cut that for many countries. PwC's table (last reviewed 4 September 2026) lists these portfolio dividend rates:

To get a treaty rate you usually file a form with your broker. If it's missing, the full rate applies.

Tax at home. Your own country may tax the dividend as income too. Many give a credit for foreign tax already paid, but not all, and not always in full. Some countries offer tax-sheltered accounts where dividends grow untaxed. Check your local tax authority's rules.

Bonus shares and stock splits: more shares, same value

Some companies pay part of a distribution as bonus shares: free new shares in proportion to what you own.

These numbers are an example. A company gives 1 new share for every 4 you hold. You had 200 shares at $50, worth $10,000. Now you have 250 shares, and the price adjusts to about $40. Check: 250 × 40 = 10,000.

A stock split works the same way. In a 2-for-1 split, your 200 shares at $50 become 400 shares at $25, still $10,000. Either way, you own the same slice of the same company, cut into more pieces. No cash changes hands.

Dividends and inflation

A dividend is paid in money, so inflation eats it too. US inflation was 3.7% in September 2026 (Trading Economics, BLS data). A 3% yield with a flat share price would lose value in real terms.

A share's appeal is that its profits, and so its dividends, can grow with prices over many years. A fixed-rate bond or deposit can't do that. That growth is not guaranteed.

When a high yield is a warning sign

A yield is high when the dividend is big, or when the price has fallen. The second case is common, and it often comes before a cut.

These numbers are an example. A company earned $2.50 a share and paid $2: a payout ratio of 2 ÷ 2.50 = 80%. If its profit halves to $1.25, keeping the $2 dividend would mean paying out 160% of earnings. A cut becomes likely.

Spending vs reinvesting dividends

Reinvesting means using each dividend to buy more shares, so next year's dividend is paid on more shares.

These numbers are an example: $10,000 invested, a 4% yearly dividend, and a share price that stays flat for 10 years. After 15% withholding, you keep 3.4% a year.

Check: 10,000 × 0.034 × 10 = 3,400, and 10,000 × 1.034¹⁰ ≈ 13,970. Reinvesting adds about $570 here, before any trading fees, and the gap widens the longer you hold.

DRIPs. A dividend reinvestment plan (DRIP), run by a company or a broker, buys more shares with each dividend automatically. Many buy fractional shares and charge little or nothing. In many countries a reinvested dividend is still taxed as if you'd received the cash.

Funds do the same job. An "accumulating" fund class reinvests dividends inside the fund; a "distributing" class pays them out to you.

Your plan

1. Look at total return, price change plus dividends, not the yield alone.
2. Use today's yield to compare options; keep yield on cost for tracking.
3. Read the company's dividend announcement for the ex-dividend date and the payment date.
4. Check the payout ratio and debt before trusting a high yield.
5. Find out the withholding rate that applies to you, and file any treaty form your broker offers.
6. Decide what you'll do with dividends (spend or reinvest) and write it down.
7. Check each dividend statement for the gross amount, tax withheld and net cash.

What to watch out for

• Buying just before the ex-date. The price drops by about the dividend, and you may owe tax on cash you effectively paid for.
• High-yield lists. A yield made high by a falling price is a warning, not a bargain.
• One-off payouts. A big special dividend doesn't mean the next one will come.
• Ignoring inflation. A 3% yield with a flat price loses value when prices rise 3.7%.
• Missing treaty paperwork. Without it, foreign dividends can be taxed at the full rate.
