Costco Just Sent Shareholders a $13 Billion Signal It Has More Cash Than It Can Use. Here’s What 200 Shares Collect

Costco Wholesale (NASDAQ: COST) declared a $30 a share special cash dividend after Tuesday’s close, about $13 billion in all and the largest in its history, which means a $6,000 check on December 4 for a retiree holding 200 shares. The board also reauthorized a stock buyback of up to $4 billion that runs to November 2030, replacing a 2023 program of the same size that had about $900 million left. The special is payable December 4 to shareholders of record at the close on November 24, and it comes on top of the regular quarterly dividend of $1.47 a share.

The $13.3 billion is twice the $15 a share Costco paid in January 2024, which cost about $6.7 billion. It is 1.44 times the $9.226 billion Costco earned in fiscal 2026 and about two-thirds of the $20.207 billion in cash it held on August 30. A check that size reads as the board saying Costco has more cash than its warehouses can use; the limit on that reading is that this is the sixth special since 2012, each paid from cash on hand, and the company kept growing after every one. The stock traded at about $1,083 in early after-hours trading against a $1,066.14 close, according to StockTitan, a gain of about 1.6%.

Consider a retired couple, 61 and 59, who left software jobs in 2021 and live in Washington State, Costco’s home state, with $3.1 million: $1.8 million in a 401(k) and an IRA, $1.1 million in a brokerage account and $200,000 in cash. They are a scenario, built to show the arithmetic. In March 2010 they bought 200 Costco shares in the brokerage account at about $61, $12,110 in all. At Tuesday’s close those shares were worth $213,228, 17.6 times what they paid and 6.9% of everything they own. They have never sold one or spent a dividend. The check that arrives December 4 forces a decision they have been putting off.

What 200 shares collect

The regular dividend pays them $294 a quarter, $1,176 a year, a 0.55% yield on the current price. The special is $6,000 at once, 5.1 years of regular dividends in one payment, and 2.8% of the position.

It is the sixth such check since they bought. Costco paid specials of $7 a share in December 2012, $5 in February 2015, $7 in May 2017, $10 in December 2020 and $15 in January 2024, according to its dividend history. On 200 shares:

The specials alone have now paid $14,800 on shares that cost $12,110: every dollar the couple put in has come back in one-time checks, before the regular dividends or the $213,228 the shares are worth.

The tax on a special dividend

A special dividend is taxed like any other dividend. For anyone who has owned the shares for more than 60 days in the 121-day window that starts 60 days before the ex-dividend date (IRS Publication 550), it is a qualified dividend, taxed at the long-term capital gains rates rather than ordinary rates. For 2026, under IRS Revenue Procedure 2025-32, the rate is 0% on taxable income up to $98,900 for a married couple filing jointly ($49,450 single), 15% up to $613,700 ($545,500 single) and 20% above that. The 3.8% net investment income tax applies above $250,000 of modified adjusted gross income for a couple and $200,000 for a single filer.

The couple’s 2026 income so far is $40,000 of interest and a small Roth conversion plus $86,200 of long-term gains and qualified dividends. After the $32,200 standard deduction their taxable income is $94,000, which leaves $4,900 of room under the $98,900 line. So $4,900 of the Costco check is taxed at 0% and $1,100 at 15%. Federal tax on the $6,000: $165. Washington State does not tax dividends. They keep $5,835.

A single filer with only dividends and gains can have up to $65,550 of gross income in 2026 and still sit in the 0% band ($49,450 of taxable income plus the $16,100 standard deduction); a couple, $131,100. Inside a traditional IRA the special loses its qualified status: it comes out later as ordinary income, $420 more in tax at 22% than the same $6,000 taxed at 15% in a brokerage account.

What happens to the stock on November 24

The record date is November 24, and with one-day settlement that is also the ex-dividend date: a buyer on November 24 does not get the $30, so Nasdaq’s opening reference price that morning is Monday’s close less $30. The money moves from the share price to the shareholder’s account: the couple’s $213,228 position becomes about $207,228 of stock plus $6,000 of cash before tax.

Costco’s own closes around the last five specials:

Each time the opening gap sat within about $3 of the dividend. Three months after the ex-date the stock was lower in four of the five cases, measured against the close before the ex-date. Five cases prove little, and each drop had its own cause (2017 was the summer Amazon bought Whole Foods), but they settle one thing: buying Costco now for the $30 does not work. The buyer pays $1,066 for a share that opens near $1,036 on November 24, collects a taxable $30, and must hold into late January for it to count as qualified.

The one decision: spend, reinvest or trim

The couple’s instinct is to reinvest, as they always have. At Tuesday’s close less $30, the $6,000 buys about 5.8 shares and puts the position back to 6.9% of their money. That choice changes nothing.

Spending it is the choice they never make, and this check is the easiest one to make it on. The special is Costco trimming their position for them, 2.8% of it, at a federal tax cost of $165. Raising the same $6,000 by selling shares would mean a gain of $5,659 and $849 of tax at 15%, since the gain lands above the 0% line. Spending the check on the national parks trip in the camper van they bought for exactly that costs less tax than any sale and leaves the position lighter.

Trimming is a separate question. A 50-share sale at Tuesday’s close raises $53,307 with a $50,280 gain and about $7,542 of federal tax at 15%, and takes the position from 6.9% to 5.2% of their money. Selling before or after November 24 comes out about the same, since the price drops by the dividend. What matters is whether 6.9% in one retailer, at 17.6 times cost, is a position they would buy today. If the answer is no, the check is the first installment of the trim, and the rest can wait for a year when more of the sale fits under the 0% line.

The bottom line

A $30 special dividend pays $6,000 on 200 shares, on December 4, to anyone who owns them at the close on November 24. For a couple with $94,000 of taxable income the federal tax is $165; in the 15% band it is $900; inside a traditional IRA it is deferred and later taxed as ordinary income. The stock will open about $30 lower on November 24, and three months after the last five specials it was lower four times out of five. Costco has now paid $74 a share in specials since 2012, $14,800 on these 200 shares, more than the $12,110 they cost. The check is Costco doing the one thing this couple would never do for themselves. Spend it.
