Trade Date and Settlement Date

When you buy or sell shares of stock, it may seem that all the action occurs at once. Yet stock transactions actually occur in two steps that take place on different days, the trade date and settlement date. Learning the tax significance of these two dates can help you manage your investments at a lower tax cost.

Trade date and settlement date

Trade date. In stock market terminology, every purchase or sale of shares is a trade. By definition, the trade date is when the terms of the deal are fixed. A buyer has agreed to pay a fixed amount for a specified number of shares of a particular security, and a seller has accepted exactly the same terms.

In most respects, this is a done deal. The seller can’t back out even if the stock price soars just moments after the trade. Likewise, the buyer is stuck even if the trade is followed immediately by a steep decline in value. In economic terms, the buyer becomes the owner at the moment of the trade.

Settlement date. In what sense is the transaction incomplete? At this point, the deal is what we might call a paper transaction. Money and shares don’t change hands immediately. Brokers need time to confirm that the transaction was properly recorded, that the seller’s account contains the number of shares that are being sold, and that the buyer’s account has enough cash. Only after they have performed these essential background tasks can delivery of cash and shares occur. This event is called settlement.

They don’t need much time, however. Settlement occurs on the first day the stock market is open after the trade date. Assuming there is no intervening holiday, a trade on Monday settles on Tuesday, and a Friday trade will settle Monday.

This schedule, known as T+1, replaced the T+2 schedule that was in effect before May 28, 2024.

Settlement may be largely invisible to retail investors. They don’t have to do anything to make settlement occur. It may appear that all the meaningful action took place on the trade date. Let’s see how the distinction makes a difference for tax purposes.

Why the date matters

In a number of situations, the trade date and settlement date may produce different tax consequences.

• We need to know whether a sale transaction occurred before or after the end of a year, so we know which year’s tax return it will appear on.
• We need to know whether the holding period was short-term or long-term at the time of a sale.
• If you sold shares at a loss, we need to know if any transaction in which you bought replacement shares occurred within the wash sale period.
• If you received a dividend, we need to know whether you held the shares long enough for it to be a qualified dividend.

In all these cases, we may get one answer when using the trade date but a different one if we measure by the settlement date. In part this is because the time for settlement is measured in business days, but the time periods used in the tax law generally use calendar days. For example, the 61-day wash sale period includes the date of sale plus the 30 calendar days before and after that date. The time between the transaction date and settlement date can be anywhere from one to four days, depending on whether a holiday and/or weekend intervenes.

General rule: trade date controls

For most purposes, the tax law uses the trade date for both purchases and sales. For example, if you sell stock with a trade date of December 31, you’ll report the gain or loss that year, even though the transaction will settle in January. Trade dates also govern in determining whether your holding period is short-term or long-term, in determining whether the wash sale rule applies, and in determining whether you have a qualified dividend.

When the settlement date matters

Share identification. One aspect of a sale transaction isn’t determined at the time the transaction is executed. We know at that time the number of shares and the number of dollars, but we don’t necessarily know which shares will be delivered. The seller may have two or more lots of shares that can be used to meet the settlement obligation. The seller can make choose which lot to sell — or change that choice — after the trade, provided the seller acts before settlement (generally considered to be the close of business on the settlement date). See How to Identify Shares.

Example. You have 100 shares of XYZ you bought years ago, and another 100 shares bought at a different price more recently. You decide to sell 100 shares. After the trade is executed, you realize the tax result will be more favorable if you identify which of these two lots will be treated as the ones sold. If you act before the transaction settles, the IRS will respect your identification.

Not all brokers offer the ability to make such a change after a trade has been executed, but doing so is allowed by IRS rules.

Short sale closed at a loss. Another situation where settlement date matters is a short sale closed at a loss. The IRS has ruled (Rev. Rul. 2002-44 [PDF]) that when you close a short sale at a loss, the tax law treats the transaction as occurring on the settlement date, not the trade date.

Example. You close a short sale position on the last trading day of the year. If the transaction produces a loss, it will be treated as occurring when the transaction settles in the following year.

This rule applies only to a loss from a short sale. In the above example, if you had a gain, it would be reported as occurring on the trade date.
