How to Build a Dividend Portfolio: Screens, DRIPs and Tax

Capital at risk. Dividend-paying shares and funds can fall in value, and companies can cut or stop their dividends at any time. This is general information, not personalised advice.

To build a dividend portfolio, screen every holding on three numbers — the yield, the payout ratio and whether free cash flow covers the dividend — then decide how much you want current income versus income that grows, spread the holdings across sectors and countries, and reinvest the dividends until you need to spend them. A broad dividend fund does most of this for you; individual shares mean doing the screening yourself. The worked numbers below show why a very high yield is more often a warning than a bargain.

This page is the portfolio-building and screening guide. For how much capital it takes to live on dividends, see how much you need to live off dividends.

The three numbers to check before you buy

1. Dividend yield = annual dividend ÷ share price. A company paying $2 a year with a share price of $50 yields 4%. The catch is that the price is in the denominator. If bad news halves the price to $25 and the dividend has not yet been cut, the yield shows 8% — the yield doubled because the business got worse, not better.

2. Payout ratio = dividend per share ÷ earnings per share. A company earning $5 a share and paying $2 has a payout ratio of 40% and keeps 60% to reinvest or cushion a bad year. A ratio above 100% means the dividend is larger than profits, which cannot last unless profits recover.

3. Cash cover = free cash flow ÷ dividends paid. Earnings include accounting items; dividends are paid in cash. If free cash flow (cash from operations minus capital spending) does not cover the dividend, the company is funding it from savings or borrowing.

What counts as a normal payout ratio differs by industry — utilities and property companies typically pay out more of their profits than technology companies — so compare a company with its own history and its peers, not with a single universal number.

Current yield or growing income?

There are two broad ways to run a dividend portfolio, and the trade-off is easiest to see in numbers. Compare 100,000 invested at a 6% yield that never rises with 100,000 at 2.5% where the dividend grows 10% a year. These are assumptions to show the arithmetic, not a forecast — real dividends can be cut, frozen or grow more slowly.

Each figure in the right-hand column is 2,500 × 1.10 raised to the power of (year − 1). On these assumptions the growing stream overtakes the flat one in year 11. The same arithmetic gives "yield on cost": a 2.5% starting yield that grows 10% a year is paying 6.5% on the original price after ten years of increases and about 16.8% after twenty.

The trade-off cuts both ways. If you need income now, a decade of lower payments is a real cost. If you will not spend the income for many years, growth matters more than today's figure — provided the company can actually keep raising it, which is what the three checks above try to establish.

Dividend Aristocrats: a screen, not a guarantee

S&P Dow Jones Indices defines the S&P 500 Dividend Aristocrats as S&P 500 companies "that have increased dividends every year for the last 25 consecutive years", and the index weights each member equally regardless of size. It is a useful filter for companies with a long record of raising payouts through recessions.

Two limits are worth knowing. The list changes: a company that cuts or freezes its dividend leaves it. And a long record says nothing about the next payment; it only tells you the board has prioritised the dividend in the past. Funds that track the index give you the whole list in one holding, at the cost of owning every member, including any that later drop out.

Reinvesting dividends (DRIP)

A dividend reinvestment plan uses each dividend to buy more shares of the same company or fund, usually including fractions of a share. The mechanics, with the price and dividend held constant so you can see the effect of reinvestment alone:

You own 200 shares priced at $40, paying $0.50 a share each quarter. The first dividend is $100, which buys 2.5 more shares. Because each quarter's dividend is paid on a slightly larger holding, after four quarters you own about 210.2 shares instead of 200 — roughly 5.1% more shares, before any change in price or dividend.

Two practical points. Reinvestment does not avoid tax: the IRS states that if you use dividends to buy more stock at its fair market value, "you must still report the dividends as income". And once you need income to live on, switching the plan off is usually simpler than selling shares.

How US dividends are taxed

For US taxpayers, the IRS splits dividends into two groups:

To count as qualified, a dividend must come from a US corporation or a qualified foreign corporation, and you must have held the stock "for more than 60 days during the 121-day period that begins 60 days before the ex-dividend date" (IRS Publication 550). Buying just before the ex-dividend date and selling soon after does not qualify.

Worked example: 10,000 of qualified dividends taxed at 15% costs 1,500. The same amount taxed as ordinary income in the 24% bracket costs 2,400 — a 900 difference. That is why payers whose distributions are mostly ordinary income, such as many REITs, are often held in tax-advantaged accounts. Outside the US, the main cost is usually withholding tax on foreign dividends; see the foreign dividend withholding tax guide.

Building blocks of a dividend portfolio

How you combine them depends on whether you need income now. Higher-income products such as covered-call funds raise distributions by giving up part of the upside; the trade-offs are covered in our guide to high-yield covered-call ETFs.

Frequently asked questions

What is a good dividend yield?

There is no single good number. A yield is more trustworthy when it sits close to the company's usual range and is covered by earnings and free cash flow. A yield far above the company's history, especially after a price fall, often means the market expects a cut.

What is a safe payout ratio?

One that leaves room for a bad year in that industry. Utilities and property companies routinely pay out a larger share of profits than technology companies, so compare a company with its own history and peers. A payout ratio above 100% means the dividend exceeds profits.

Are reinvested dividends taxed?

Yes, in the US. The IRS says dividends used to buy more shares at fair market value must still be reported as income in the year they are paid.

How long do I need to hold a stock for a qualified dividend?

More than 60 days during the 121-day period that begins 60 days before the ex-dividend date, according to IRS Publication 550.

Is dividend investing better than growth investing?

Not by itself. A dividend is cash the company pays out of its own value, so what you compare is total return: price change plus dividends. Dividend investing suits someone who wants part of that return as regular cash, and growth-oriented holdings suit someone who will not spend the income for many years. Many portfolios hold both. Whichever you choose, dividends are not guaranteed: in a recession, companies short of cash cut or suspend them, which is exactly when the three checks above earn their keep.
