The 3 Keys to ETF Tax Efficiency

Since their inception, exchange traded funds (ETFs) continue to grow their market share and popularity with investors. The tax efficiency for which they are known comes down to three primary mechanisms from which the vehicle wrapper benefits.

ETFs and the Primary Market

Exchange traded funds benefit from their ability to trade “in-kind” on the primary market. When demand outstrips supply, the ETF issuer is able to trade with an authorized participant (AP). This trade occurs in the primary market, where the issuer trades a pro-rata piece of its portfolio to the AP in exchange for shares.

This transaction is an “in-kind” trade and goes in reverse when shares need to be redeemed. Redemptions also allow the ETF issuer to select lower cost bases by picking which tax lots to push out. This affords even greater tax efficiencies.

Capital gains are not triggered during in-kind trades. This means that any underlying securities with unrealized gains traded from the issuer to the AP don’t trigger for shareholders.

“Investors can maintain a higher level of unrealized capital gains on their books to be realized only when they choose to sell the ETF shares,” explained Tyler Williams, VP, ETF capital markets and product at Natixis Investment Managers, in a recent paper.
