The IRS filing season report provides aggregate numbers of U.S. federal tax returns received and processed. For the 2024 filing season to that date, the IRS reports **"Total returns received" of over 146 million** and breaks them down by e‑filed (from paid preparers and self‑prepared) vs. paper‑filed. The IRS does **not** attribute shares to specific private vendors like TurboTax; instead it gives total volume, which can be compared against vendor‑reported volumes to estimate rough market shares.

Intuit stated that TurboTax "will help approximately 69 million U.S. taxpayers file their taxes this season." The release notes that, per IRS data, there were about 161 million individual federal income tax returns filed for the prior tax year, implying that TurboTax expected to handle around 40–45% of individual returns, not 60%. The document presents this 69 million figure as the scale of TurboTax’s reach in the U.S. consumer tax segment.

In its 2024 Form 10-K, Intuit describes its Consumer Group segment and notes that TurboTax is "the leading provider of consumer tax preparation products and services in the U.S." The filing states that TurboTax "has maintained the leading share of U.S. do-it-yourself tax software for many years" and that the company "processed tens of millions of U.S. federal tax returns" for individuals in the most recent tax season. The filing does not claim that TurboTax handles 60% of all U.S. tax preparation, but instead refers to leading share within the do‑it‑yourself (DIY) segment.

IRS Statistics of Income data show that for tax year 2022 there were approximately 163 million individual income tax returns filed. Separate IRS tables on filing methods report that about 55–60% of individual returns are self‑prepared (without a paid preparer) while roughly 40–45% are completed by paid tax professionals. These IRS publications do not break out market share by software brand (such as TurboTax) and therefore do not support a direct statement that any one provider handles 60% of all preparation.

For the 2024 filing season through the end of the reporting period, IRS filing season statistics indicated over 160 million individual returns received. The IRS reports that more than 90% of individual returns are e‑filed but does not specify which software or service was used. The data distinguish between returns prepared by paid preparers and those that are self‑prepared, but there is no attribution of specific percentages to TurboTax or any commercial vendor.

In its fiscal 2024 earnings materials, Intuit states that its Consumer Group, which includes TurboTax, "helped approximately 47 million consumers" file their taxes in the most recent tax season. The company also highlights that TurboTax remains the "No. 1 market leader in do‑it‑yourself tax preparation" in the United States but does not claim a specific percentage of all U.S. tax returns. Intuit’s metrics are based on its own customer counts and are not directly tied to IRS totals for all individual returns filed.

In its discussion of the Consumer Group (TurboTax), Intuit notes: "TurboTax **remains the leading provider of do‑it‑yourself tax preparation** in the U.S." and references its "strong share" of the total DIY category. The release does not state that TurboTax handles 60% of **all** U.S. tax preparation, but characterizes its leadership specifically within the **DIY tax** market.

In its discussion of the Consumer Group, Intuit (owner of TurboTax) typically reports that TurboTax is the leading do‑it‑yourself tax preparation software product in the U.S. For example, recent 10‑K filings describe the Consumer Group as providing "do‑it‑yourself and assisted tax preparation offerings," and state that TurboTax is the "**leading U.S. do‑it‑yourself tax preparation**" offering, serving tens of millions of consumers each year. While exact current percentage market share figures are often omitted, the filing consistently emphasizes TurboTax’s number‑one position in the DIY tax segment by revenue and customer count.

A 2024 GAO report on tax filing notes that "about 54 percent of individual income tax returns for tax year 2021 were prepared by paid preparers, while about 46 percent were self‑prepared using tax software or paper forms." The report discusses commercial tax software and the IRS Free File program but does not name TurboTax as handling a specific share such as 60% of all tax preparation. The GAO findings show that individual paid preparers collectively handle a substantial portion of returns, limiting the maximum share available to any single software provider.

ProPublica, citing an analysis of IRS data, reports that in 2019 "nearly 40% of U.S. taxpayers filed online and some 40 million of them did so with TurboTax, far more than with any other product." It also states that "in 2019, according to a ProPublica analysis of IRS data, the two giants [Intuit and H&R Block] accounted for 81% of all individual returns filed using tax prep software." The article underscores that TurboTax was handling tens of millions of returns but describes this share in the context of online and software‑prepared returns, not as a percentage of all U.S. tax returns filed by every method.

In its Form 10‑K, Intuit states that it "is the leading provider of do‑it‑yourself income tax preparation products and services" and that TurboTax is the "No. 1 U.S. do‑it‑yourself tax preparation product." The filing notes that Intuit’s Consumer Group serves "more than 45 million taxpayers" in a typical tax year. The company does not claim that TurboTax prepares a majority of all U.S. tax returns, instead limiting its leadership claim to the do‑it‑yourself segment of the tax preparation market.

Reporting on Intuit’s earnings, Reuters writes that TurboTax is "**the most widely used do‑it‑yourself tax preparation software** in the United States" and cites analysts noting its dominance in the **DIY tax** segment. The article does not state that TurboTax handles 60% of all U.S. tax preparation, but underscores its leading position among **self‑filers** using software.

In describing the U.S. tax filing landscape, the paper notes that "a substantial share of individual income tax returns are filed with the assistance of **paid tax preparers**, while the rest are **self‑prepared using software or manually**." It cites IRS data showing that roughly **half to slightly more than half** of individual returns are prepared by professionals in many years. The study does not single out TurboTax, but its breakdown implies that **no single software vendor** is likely to account for 60% of **all** U.S. tax preparation when professional preparation is included.

Pew Research Center, using IRS data, reports that in 2019 "**51% of all individual income tax returns** were prepared by a paid tax professional" while "48% were self‑prepared." It adds that the share of self‑prepared returns has been rising over time. Pew does not single out TurboTax, but its figures imply that any claim that a single vendor handles a majority of *all* U.S. tax preparation would have to be reconciled with the continued large role of paid preparers and other software products.

ProPublica’s investigation into Intuit and TurboTax reports that TurboTax "is by far the most popular commercial tax software" in the United States, describing it as having a dominant share of the do‑it‑yourself market. The article cites industry estimates that TurboTax controlled roughly two‑thirds of the DIY software segment at various points, not of all U.S. tax preparation including paid preparers. The story emphasizes that H&R Block and thousands of independent preparers also handle a large fraction of U.S. tax returns.

The article analyzes U.S. **tax preparation software** spending using transaction data and notes: "TurboTax has increased its share of sales. In May 2021, TurboTax’s share of sales was **73 percent**, 3 percentage points higher than in July 2020 and 10 percentage points higher than in April 2019." It clarifies that this is among top **online tax prep competitors** (TurboTax, H&R Block, TaxAct, TaxSlayer, Jackson Hewitt), not all U.S. tax preparation including manual or professional preparers.

The Wall Street Journal reported that Intuit’s TurboTax "controls about two-thirds of the market for consumer tax-preparation software" in the U.S., citing industry research. The article makes clear that this roughly 66% figure refers to the market for DIY consumer tax software, and not to all U.S. tax returns including those prepared by professional tax preparers. The story notes that millions of taxpayers still use accountants, H&R Block storefronts, and other services.

In a corporate blog post breaking down tax season metrics, Intuit states that "more than 40 million" federal and state returns were prepared and filed using TurboTax in a recent tax year. The post positions TurboTax as the market leader in U.S. DIY tax preparation but does not claim that TurboTax is used for 60% of all U.S. tax preparation. Instead, it frames the figure relative to the DIY software category and to the total number of individual returns filed with the IRS.

The IBISWorld report on Tax Preparation Services in the US estimates the market size at about $15.0 billion in 2026 and lists Intuit Inc. as the company holding the most market share in the tax preparation services industry. However, the report frames this in terms of revenue share within the tax preparation services market and does not quantify Intuit’s share as a percentage of all individual tax returns filed with the IRS. The distinction between revenue market share and share of total returns is emphasized in the methodology section.

Discussing the IRS Direct File pilot, Kiplinger notes that "according to IRS data, about 55% of individual federal income tax returns are prepared and filed by paid professionals, while 45% are self‑prepared using software or paper forms." The article describes TurboTax and H&R Block as dominant in the software segment but does not state that TurboTax alone accounts for 60% of all U.S. tax returns. Instead, the piece explains that TurboTax and a few competitors share the self‑prepared portion of the market.

This chart shows the **market share of leading online tax preparation software in the United States**, based on number of users. For recent tax years, **TurboTax holds well over half of the online tax software market**, with H&R Block and other providers sharing the remainder. The data is explicitly limited to the **online tax software segment** and does not cover all U.S. tax preparation, including in‑person preparers and manual filing.

NBC News writes that TurboTax "accounts for roughly two-thirds of all tax software purchases" in the U.S., citing market research on the consumer tax software segment. The piece clarifies that the figure refers to the tax-software market and that millions of returns are still prepared by professional preparers or other services. It does not state that TurboTax handles 60% of all U.S. tax preparation overall.

The AAJ report, citing public filings and market research, states that "Intuit’s TurboTax product dominates the do‑it‑yourself tax preparation market, serving tens of millions of filers every year." It also references findings that TurboTax and H&R Block together control the vast majority of the tax software segment. However, the report does not attribute 60% of all U.S. tax returns to TurboTax; its dominance is described in relation to the do‑it‑yourself and software markets rather than all returns filed.

ITEP describes Intuit’s TurboTax as a "dominant" player in the consumer tax preparation market and notes that the company has received hundreds of millions of dollars in tax credits while marketing its tax software to tens of millions of Americans. The report criticizes the concentration of market power but does not quantify TurboTax’s share of all U.S. tax returns as 60% or any other specific percentage. Its discussion centers on lobbying, tax subsidies, and the implications of Intuit’s market dominance.

In its company profiles, the report describes TurboTax: "TurboTax: With **over 40 million users annually**, TurboTax remains the market leader in the U.S. and supports over 190 tax forms. **It processed over 74 million** [returns]." The report frames these figures within the **tax preparation software market**, rather than total U.S. returns that also include professionally prepared and paper‑filed returns.

The article notes that in 2018 "TurboTax was the most popular tax preparation software in the United States, holding a 66.6% market share of self‑prepared returns" according to industry data. It contrasts this with other software such as H&R Block at Home, TaxACT, and others, indicating that TurboTax is dominant among self‑prepared returns. The 66.6% figure applies only to the subset of returns that taxpayers prepare themselves with software and does not represent 60% of all U.S. tax returns filed.

The entry describes TurboTax as "a software package for preparation of American and Canadian income tax returns, produced by Intuit." It notes that "**TurboTax is a market leader in its product segment**, competing with H&R Block Tax Software and TaxAct." While the article does not provide a precise current percentage, it characterizes TurboTax as the leading U.S. consumer tax preparation software product.

Discussing the shift from professional preparers to software, Intuit writes that "Tax software is the **fastest growing choice** of U.S. taxpayers, growing at a double digit pace for the past 10 years." It adds that "Last year, more than **36 million people used tax software**" and states that professionally prepared returns are "flat or down slightly." Although the post is older and does not specify a percentage for TurboTax alone, it frames TurboTax as a leading product benefiting from this growth in software-based preparation.

On its product page, Intuit markets TurboTax as the leading U.S. tax software, stating: "**#1 best‑selling tax software: Based on aggregated sales data for all tax year 2024 TurboTax products.**" This indicates that, at least within the category of consumer tax software, TurboTax holds the largest share of sales among competing products in the U.S. market.

Adthena’s pay‑per‑click (PPC) search advertising analysis for U.S. tax services shows relative click shares rather than total tax prep market share. In one 2026 data row, Adthena reports values such as "23.5%" and "22.92%" click share for leading brands on Google search ads. The commentary notes that "H&R Block surged with a **4.03% click share increase, while TurboTax faced a 3.96% decline. TaxAct gained 0.88%..." This reflects competition dynamics in online ad traffic, not necessarily overall tax preparation volume, but shows TurboTax as one of the top PPC competitors.

Industry and media reports commonly describe TurboTax as having on the order of 60–70% share of the U.S. consumer DIY tax software market, meaning among individuals who choose software rather than professional preparers. However, IRS and GAO data show that only about 40–45% of individual returns are self-prepared at all, with the rest completed by paid preparers. Combining these facts implies that TurboTax would handle something like 25–35% of all U.S. individual returns, not 60% of all U.S. tax preparation. No authoritative government or SEC source states that TurboTax handles 60% of total U.S. tax preparation.
