What Is an After-Tax Return Disclosure for a Fund?

Updated July 9, 2026 6 min read

A fund’s headline return tells you what it earned. An after-tax return disclosure tells you something closer to what an investor might have actually kept, and funds are often required to show both.

The short answer

An after-tax return disclosure is a standardized figure showing what a fund’s return would have looked like after accounting for the taxes generated by its distributions, based on a set of assumed tax rates. Funds typically show this alongside two variations: one assuming shares are still held, and one assuming shares are sold at the end of the period. Both are estimates meant for comparison purposes, not a prediction of any individual investor’s actual tax bill.

Two versions of the same idea

Why the assumptions matter

These figures use standardized assumed tax rates set by disclosure rules, not any individual investor’s actual tax bracket, filing status, or state taxes. That means the disclosed after-tax return is a useful point of comparison between funds, but it isn’t a personalized number — an investor’s real outcome depends on their own tax situation, which can be quite different from the assumptions used in the disclosure.

Why this figure exists at all

Two funds can report identical pre-tax returns while behaving very differently in a taxable account, depending on how much they distribute and how those distributions are taxed. After-tax return disclosures were designed to make that difference visible, giving investors a standardized way to see how much of a fund’s stated performance would have survived taxes under a common set of assumptions. It’s one of several metrics used to compare tax efficiency across similar funds.

Where this figure is most useful

This kind of disclosure matters most for funds likely to be held in taxable brokerage accounts, since the whole concept is about the tax drag on distributions. A fund held inside a retirement account doesn’t generate the same year-to-year tax consequences, so after-tax return figures are far less relevant there — a reminder that where a fund is held changes how much its tax profile matters in the first place.

What to weigh

Because these figures rely on standardized, sometimes dated, assumed tax rates rather than an investor’s actual situation, they’re best used as a relative comparison tool between similar funds rather than a literal forecast. Tax rules and rates are set by the government and change over time, so even the assumptions behind these disclosures shift periodically. Reading the fine print on what assumptions were used is worth doing before treating the number as gospel.

The takeaway

An after-tax return disclosure exists to strip away some of the mystery around how taxes affect fund performance, using consistent assumptions so investors can compare funds on a more level footing. It’s a useful reference point, not a personalized tax projection, and its relevance depends heavily on the type of account in which a fund is actually held.
