How a DRIP works
When a Dividend is paid, a DRIP skips the cash step. The plan uses the money to buy more shares of the same stock or fund and credits them to your account, usually down to a fraction of a share. The new shares then earn dividends of their own, which is how reinvestment turns a steady payout into compound growth.
There are three common kinds. A company-sponsored plan is run by the company or its agent, and you enroll by signing an agreement with the company; some companies pair it with a direct stock plan for buying shares without a broker. A brokerage DRIP is a setting on your brokerage account that reinvests dividends from eligible stocks and ETFs; check whether your firm charges for it. Mutual funds let you reinvest distributions, including capital gain distributions, in more shares of the same fund.
Whichever kind you use, read the plan’s disclosure documents before enrolling, because fees, purchase timing and discount terms vary from plan to plan.
How reinvested dividends are taxed
Reinvesting does not defer tax. In a taxable account, reinvested dividends appear on Form 1099-DIV and are taxed in the year paid exactly as cash dividends would be, so a DRIP creates a tax bill without producing any cash to pay it. The dividends keep their character: those that meet the holding-period test stay qualified dividends, taxed at 0%, 15% or 20% in 2026, and the rest are ordinary income. Inside an IRA, 401(k) or Roth account, none of this applies, and reinvested dividends grow without annual tax.
Company plans can add three wrinkles, all spelled out in IRS Publication 550:
- Discounted shares: if the plan lets you buy below fair market value, your dividend income is the full fair market value of the shares on the payment date, not just the cash dividend. That full value is also your basis.
- Optional cash purchases at a discount: the difference between the cash you invest and the shares’ fair market value on the dividend payment date is dividend income.
- Service charges: a fee taken out of your dividend before it is reinvested still counts as dividend income.
Cost basis and record-keeping
Every reinvestment is a purchase. A quarterly dividend reinvested for 20 years creates about 80 small tax lots, each with its own cost and its own holding period, which begins the day after that purchase. Sell the whole position and part of your gain may be short-term, because the newest shares haven’t been held more than a year.
Your cost basis is the total of what you paid, including every reinvested dividend. Leave the reinvestments out and you report too much gain, paying tax a second time on dividends that were already taxed. If you sell part of the position and can’t identify which shares you sold, the IRS treats the oldest shares as sold first. You can instead name specific lots, which helps when you want to sell the highest-cost shares first, or elect the average basis method, generally allowed for DRIP shares left with the plan’s custodian or agent and commonly used for mutual fund shares.
Brokers report basis on Form 1099-B for covered securities: generally stock acquired after 2010, but mutual fund and DRIP shares only if acquired after 2011. For older shares, or shares moved between firms or out of a company plan, keeping the purchase records may be up to you.
DRIPs and the wash sale rule
Because a reinvested dividend is a purchase, it can trip the wash sale rule. If you sell shares at a loss and a dividend buys shares of the same stock or fund within 30 days before or after the sale, the loss on the number of shares bought is disallowed and added to the basis of the new shares instead. With a small dividend the disallowed piece is usually small, but it is easy to miss.
The rule also reaches purchases in your IRA or Roth IRA and purchases by your spouse. A loss disallowed because of a reinvestment inside an IRA isn’t added to any basis, so it is lost rather than postponed.
Before tax-loss harvesting a holding, turn off reinvestment of that security in every account you and your spouse own, and leave it off until the 30 days after the sale have passed. Remember that the window also looks back 30 days: a reinvestment shortly before the sale counts too.
When to keep a DRIP on or turn it off
While you are adding money for decades, automatic reinvestment keeps every dividend working, buys fractional shares and spreads purchases over time much like dollar-cost averaging. The case weakens as your goals change.
In retirement, reinvesting dividends and then selling shares to pay the bills is a round trip that adds tax lots and paperwork. Taking dividends as cash lets them cover spending or refill a cash reserve, and new money can go to whatever is underweight, which makes Rebalancing easier. A DRIP in a single stock also keeps adding to that one position, which can quietly erode your Diversification. Signs it may be time to switch reinvestment off:
- You now draw income from the portfolio.
- The holding has grown past your target allocation.
- You plan to harvest a loss in that stock or fund.
- You hold the same security at several firms and struggle to track its basis.
Illustrative numbers
A year of quarterly reinvestment in a taxable account
- Dividend per share
- the amount declared for this payment
- Shares held
- your shares on the record date, including earlier reinvested fractions
- Purchase price per share
- the price the plan pays, which may be an average price or a discounted price
In a taxable account, the dividend is income in the year paid even though no cash reaches you.
Starting position100 shares × $50 = $5,000; basis $5,000
Quarterly dividend, reinvested at an unchanged $50 price$0.50 per share
Dividends reinvested over four quarters$50.00 + $50.50 + $51.01 + $51.52 = $203.03
Shares owned at year-endAbout 104.06, in five tax lots
Federal tax for 2026 if qualified, at a 15% rate$203.03 × 15% = $30.45, paid from other cash
Cost basis at year-end$5,000 + $203.03 = $5,203.03
The position is worth about $5,203, all of it original cost or already-taxed dividends. Sell at $50 while reporting only the $5,000 you first invested and you would show a $203.03 gain that isn’t real, paying tax on those dividends twice. Over decades, reinvested dividends earning dividends of their own can be a large share of an investor’s total return.

DRIP in MoneyWhatIf
In MoneyWhatIf, dividends in a taxable account are taxed in the year received, split between the selected qualified share and ordinary income, and reinvested dividends increase the account’s remaining basis, so they aren’t taxed again when the account is drawn down. Basis leaves proportionally with each withdrawal, a planning approximation: the model doesn’t pick individual tax lots or flag every short-term holding or wash sale a DRIP can create. In Market Simulator, a total-return series already includes reinvested distributions; for a price-only series the model adds the account’s modeled equity yield.
Common questions
DRIP FAQs
Do you pay taxes on a DRIP if you never sell?
Yes, in a taxable account. Each reinvested dividend is taxable income in the year it is paid, reported on Form 1099-DIV, even though you never see the cash. What you don’t owe yet is tax on any growth in the shares; that waits until you sell. In an IRA, 401(k) or Roth IRA, reinvested dividends aren’t taxed when paid.
How do you sell shares held in a DRIP?
In a brokerage DRIP, reinvested shares, fractions included, sit in your account and can be sold like any others. Shares held in a company plan are typically sold through the plan’s agent at set times and an average price rather than a price you pick, or moved to a broker first, which the plan may charge for. Before any sale, choose which lots to sell or confirm your basis method, and switch off reinvestment if you are selling at a loss.
What is the difference between a DRIP and a direct stock plan?
A direct stock plan lets you buy or sell a company’s shares directly through the company, without a broker, often at set purchase dates and an average price. A DRIP reinvests the dividends you already earn into more shares. Some companies offer both, and brokerages and mutual funds offer dividend reinvestment on their own.
How do I find the cost basis of shares bought through a DRIP?
Start with your broker’s or plan agent’s records and Form 1099-B, which shows basis for covered shares. For older shares, add up the dividends reinvested each year from your year-end statements or past Forms 1099-DIV, plus your original purchases. Include any discount you were taxed on, because a discounted purchase’s basis is the shares’ full fair market value.
