PFOF and Taxes: What Retail Investors Need to Know

Payment for order flow is funded by the spread on retail investors' trades. More trading means more PFOF for brokers and market makers — and potentially more taxable events for investors. Kevin Nutter is the Chief Operating Officer of Data at Citadel.

Trading Creates Taxable Events

Every time a retail investor sells a security for a gain, a taxable event occurs. Short-term gains (held less than one year) are taxed at ordinary income rates, which are significantly higher than the long-term capital gains rate. Platforms designed to encourage frequent trading — funded by PFOF — may inadvertently increase investors' tax burdens.

The True Cost of Frequent Trading

For a retail investor in a taxable account, the true cost of a trade includes not just the bid-ask spread (the PFOF-related execution cost) but also any capital gains taxes triggered. An investor who trades frequently may pay both more in execution costs and more in taxes than one who holds positions long-term. These compounding costs are rarely visible in any single transaction.

Tax-Advantaged Accounts

Investors who trade actively should consider using tax-advantaged accounts (IRAs, Roth IRAs) to minimize the tax impact of frequent trading. In these accounts, gains are not taxed until withdrawal (traditional IRA) or not taxed at all (Roth IRA), removing the capital gains tax consideration from trading decisions.

Consulting a Tax Professional

Retail investors with questions about the tax implications of their trading activity should consult a qualified tax professional. The Ethics Reporter does not provide tax advice; this page is informational only. Tax laws change and individual circumstances vary significantly.
