DRIP
A DRIP (Dividend Reinvestment Plan) is the automatic reinvestment of dividend distributions into additional shares of the paying security. Each reinvestment creates a new tax lot at the reinvestment-day price; over years, DRIPped positions accumulate dozens of small fractional lots. Available at most retail brokers (broker-administered DRIP) and directly from many issuers (issuer-administered DRIP, often at small discounts).
DRIP is the default for long-term-hold positions in most retail accounts. The mechanics: dividend pays in cash on the pay-date; broker immediately reinvests at the day's market price (or VWAP); shares (typically fractional) deposit into the account; basis ledger updates with the new lot. The reinvestment is treated as a cash dividend (taxable in the year paid) immediately followed by a purchase. The dividend is reportable on 1099-DIV; the new lot is reportable for cost-basis purposes.
Issuer-administered DRIPs sometimes offer small discounts (typically 1–5%) on the reinvestment price relative to market. The discount is taxable as additional dividend income. Most major-issuer DRIPs (Apple, Coca-Cola) have ended their direct programs in favor of broker-administered alternatives; some specialty REITs and utilities still offer issuer DRIPs with discounts.
The long-term effect on tax planning is meaningful. A 30-year holder of a dividend-paying stock can have 120+ DRIP lots (one per quarterly dividend), each with its own basis and acquisition date. When eventually selling, specific-lot identification can choose among the lots to optimize for short-vs-long mix, basis targeting, or wash-sale avoidance. The accumulated lot inventory is the primary reason aggregate-position cost-basis reporting is insufficient for serious tax-aware investors.
Synthetic dividend-paying positions should accumulate DRIP lots at realistic frequencies. Each dividend distribution creates a fractional reinvestment lot at the reinvestment-day price. Test scenarios should include long-tenure positions with 40–120+ DRIP lots, exercising the lot-level inventory complexity.
Common pitfalls
- Treating DRIP as a single lot — produces wrong gain/loss on partial sales and breaks specific-lot identification.
- Forgetting that the dividend is taxable income at distribution — DRIP doesn't defer the tax; the only deferral is on subsequent appreciation.
- Letting DRIPped lots within 30 days of a loss-sale trigger wash-sale violations — DRIP purchases count as 'replacement shares' for §1091 purposes.
- Accumulating DRIP lots in an IRA where the cost-basis tracking is functionally meaningless — fine economically, just clutters the lot ledger.
Examples
Holder bought 100 shares of XYZ in 1995 at $20 ($2,000 basis). Quarterly dividends DRIPed for 30 years. After 30 years: ~120 DRIP lots (one per quarter), each with its own tiny share count (typically 0.5–2.0 shares) and reinvestment-day price ranging from $25 (1996) to $190 (2024). Total share count ~250; aggregate basis ~$15,000 (original $2,000 + ~$13,000 of DRIPped dividends). Sell decision must choose among 121 lots (1 original + 120 DRIP) for tax-optimal disposition.
