What Is a Synthetic DRIP at a Brokerage?
Dividend reinvestment sounds like a single, uniform feature, but the mechanics behind it can differ quite a bit depending on who’s actually running the program. A “synthetic” DRIP is the version most people using an ordinary brokerage account are actually enrolled in.
The short answer
A synthetic DRIP is a reinvestment program run by the brokerage itself rather than by the company that pays the dividend. Instead of forwarding cash to an official company-sponsored plan, the broker takes the dividend and uses it to buy shares for you on the open market, generally at the prevailing price on that day. It functions like a traditional DRIP from the shareholder’s point of view but the purchase happens through the broker’s own systems.
How it differs from an official company DRIP
An official, company-sponsored dividend reinvestment plan is set up and administered directly by the company (or its transfer agent), and the shares are typically issued or purchased through that specific program rather than bought on the open market by a broker. A synthetic DRIP skips that structure entirely. The brokerage collects the dividend on your behalf, treats it as available cash, and places a market purchase order for more of the same stock or fund, often the same day the dividend is paid. The end result — more shares, no dividend cash sitting idle — looks similar, but the path getting there is different.
Why the distinction matters
- No purchase discount. Some official plans offer shares at a modest discount to the market price as an incentive to reinvest; a broker’s synthetic version generally buys at the full going market price, since it’s simply executing a routine trade. See how that discount question plays out at brokerage-run DRIPs for more detail.
- Ownership stays in street name. Shares bought through a synthetic DRIP are held in the brokerage account like any other holding, rather than registered directly with the company’s transfer agent.
- Execution timing can vary. Because the broker is placing a market order rather than routing cash into a dedicated plan, the exact purchase price and timing depend on the broker’s own process.
What this means for fractional shares and taxes
Dividend amounts rarely divide evenly into whole shares at the current market price, so a synthetic DRIP commonly results in fractional share purchases, handled the same way the broker handles fractional shares elsewhere in the account. Each reinvestment purchase also becomes its own tax lot, which is worth keeping in mind since frequent, small reinvestments over years can add up to a long list of individual purchase records.
The takeaway
A synthetic DRIP delivers the same basic outcome as a traditional dividend reinvestment plan — dividends convert into more shares instead of cash — but it runs through the broker’s own market-purchase process rather than a company-administered program. Knowing which type is in place matters mainly for understanding pricing, discounts, and how the resulting shares are tracked, since the two aren’t mechanically identical even when the visible result looks the same.
