Collaboration Between Stanford and the Department of the Treasury: Black Taxpayers Are Targeted for Audit More Than Others

According to Stanford RegLab, Black taxpayers receive IRS audit notices at least 2.9 times more frequently than non-Black taxpayers and possibly as much as 4.7 times more often. The team’s research showed that a set of internal IRS algorithms causes racial differences in audit selection. Goldin compared them to the recipe for Coca-Cola: “It’s completely secret.”

According to Stanford RegLab, Black taxpayers receive IRS audit notices at least 2.9 times more frequently than non-Black taxpayers and possibly as much as 4.7 times more often.

The new study included research by Daniel E. Ho, the William Benjamin Scott and Luna M. Scott Professor of Law at Stanford Law School, faculty director of the Stanford RegLab, a senior fellow at the Stanford Institute for Economic Policy Research, Hadi Elzayn, a researcher at the Stanford RegLab, Evelyn Smith, Ph.D. candidate at the University of Michigan, and Arun Ramesh, a pre-doctoral fellow at the University of Chicago; Jacob Goldin, a professor of tax law at the University of Chicago; and economists in the U.S. Department of Treasury’s Office of Tax Analysis.

The researchers concluded that the disparity “is unlikely to be intentional on the part of IRS staff.”

The team’s research showed that a set of internal IRS algorithms causes racial differences in audit selection. Goldin compared them to the recipe for Coca-Cola: “It’s completely secret.”

To better understand this audit selection bias, the research team modeled the racial impact that various alternative audit selection policies might have.

The result showed how the IRS could change its secret algorithm to make it less unfair to people of different races.

“The IRS should drill down to understand and modify its existing audit selection methods to mitigate the disparity we’ve documented,” Ho said.

“And we’ve shown they can do that without sacrificing tax revenue.”

Although there have been long-standing questions about whether the IRS uses its audit powers somewhat, Ho said it was challenging to study because tax returns are private.

The IRS’s approach to audit decisions was confidential.

That changed when, on his first day in office, President Joe Biden signed Executive Order 13985. This order requires all federal agencies to examine how their programs affect racial and ethnic equity.

To apply that order to the IRS tax return audit program, economists at the Treasury Department worked with the Stanford RegLab team to analyze more than 148 million tax returns and about 780,000 tax returns for 2014. The RegLab team used anonymous data to do the analysis.

Even with all that information, the research team found that tax returns do not ask for a person’s race or ethnicity.

So, the team adapted and improved on a state-of-the-art approach that uses first names, last names, and geography (U.S. Census block groups) to predict the probability that a person identifies as Black.

And they confirmed their racial identification results using a North Carolina sample of voter registration records. In that state, until recently, when people registered to vote, they had to check a box for race and ethnicity.

After finding that Black taxpayers were 2.9 to 4.7 times more likely to be audited than non-Black taxpayers, the team looked at why this might be the case.

They suspected that the problem lay with an IRS algorithm’s use of the Dependent Database, which flags a potential problem and generates an audit letter to the taxpayer.

That instinct proved correct in that most racial differences were found in so-called “correspondence” audits. These audits are done by mail rather than in person.

The team also found that the IRS audits people more often who claim the Earned Income Tax Credit (EITC). The EITC helps low- and moderate-income people.

But claiming the EITC only explains a small percentage of the observed racial disparity.

The largest source of disparity occurs among EITC claimants. Indeed, Black taxpayers accounted for 21% of EITC claims but were the focus of 43% of EITC audits.

The racial disparity in audit rates persists regardless of whether EITC claimants are male or female, married or unmarried, raising children, or childless.

But it is most extreme for single male taxpayers claiming dependents (7.73% for Black claimants; 3.46% for non-Black claimants) and for single male taxpayers who did not claim dependents (5.66% for Black; 2% for non-Black).

Perhaps the most striking statistic is this: A single Black man with dependents who claims the EITC is nearly 20 times as likely to be audited as a non-Black jointly filing (married) taxpayer claiming the EITC.

Although the team does not know precisely what algorithm the IRS uses to choose audits, they thought of several possible reasons for high audit rates.

First, they tried an “Oracle” approach. They used a dataset called the National Research Project (NRP).

Because each tax return in this dataset was subjected to a line-by-line audit, the amount of underreported tax liability is known.

So, the researchers looked at what would happen if the IRS selected taxpayers based on the known amount of underreported tax in the NRP dataset.

The result: The racial difference in audit selection flips.

The IRS would audit more non-Black taxpayers than Black taxpayers to catch the most underreported income tax.

The team also used the NRP dataset to train a model to predict the likelihood that a taxpayer has underreported income and the magnitude of a taxpayer’s underreporting for the entire 2014 dataset.

They found that an approach focused just on the likelihood that there’s underreporting of at least $100 would result in auditing more Black taxpayers (as was observed).

By contrast, focusing on the magnitude of underreporting (the amount of money unpaid by a taxpayer) would yield a result much closer to the oracle: More non-Black taxpayers would be audited than Black.

“The choice to focus on whether there is underreporting, as opposed to the magnitude of underreporting, is connected to broader structural sources of economic inequality and racial justice,” Smith said.

Because far more Black taxpayers have lower income, they have less opportunity to underreport substantial amounts of income, the researchers concluded.

By contrast, Smith said, “focusing audits on the amount of underreported income will disproportionately end up focusing on higher income individuals who are less likely to be Black taxpayers.”

Finally, the team wondered if the racial disparity in audits springs from IRS and congressional concerns about refundable tax credits, including the EITC and several others.

When someone claims one of these social security tax credits, they receive a refund even if they did not pay any taxes.

And some in government think it’s more important to avoid paying money to someone who claims it inappropriately than to collect all the tax dollars due from someone engaged in some other form of tax evasion.

To test the hypothesis that this approach would have a disparate impact on Black taxpayers, the team examined what would happen if the IRS focused audits specifically on the underreporting due to over-claiming of refundable tax credits (the EITC as well as two others) rather than total underreporting.

Their findings: This policy would result in Black taxpayers being audited at rates like what the team observed in the 2014 data.

Seventy percent of IRS audits happen through the mail, and 50% involve EITC claimants.

The team found that correspondence audits of EITC claimants are easy to trigger compared to labor-intensive field audits, cost very little, and require minimal effort by IRS personnel.

Unfortunately, the burden of correspondence audits on EITC claimants is more likely to fall on lower-income individuals, whose tax returns are less complex and less likely to lead to litigation, according to a recent study by the same research team.

In their new work, the team found that additional aspects of the IRS audit selection process have a racially disparate impact in the United States.

For example, even among correspondence audits of EITC claimants, the IRS devotes fewer resources to auditing EITC returns with business income.

The team concluded suggested that it’s because it would be more expensive to audit EITC returns with business income (about $385 per audit compared to $29 per audit for EITC claimants with no business income), Elzayn said.

And the team found this cost-saving measure has a disparate impact on Black taxpayers, who make up only 10% of EITC claimants reporting business income but 20% of EITC claimants who don’t report business income.

Yet even if IRS resource limits explain some of the racial disparities the team observed, they don’t explain all of them.

“Even holding fixed how many audits are devoted to EITC claimants who report business income, we still observe racial disparities,” Elzayn said.

The study’s authors have not made any formal recommendations for making the IRS audit selection algorithm more just.

Instead, they have written about the possible effects of alternative policies. This allows the IRS to reduce the racial impact of its system of choosing auditors.

These include predicting and focusing on the magnitude of taxpayers’ underreported income rather than just the likelihood of it; using IRS resources to audit more complex returns rather than focusing only on the simpler ones that are cheaper to audit; and viewing dollars as equal whether they are to be paid in refundable credits or received in taxes.

Before Biden signed the Racial Justice Executive Order that engendered this research project, the IRS needed more impetus and the ability to do that.

Now that they know the equity implications of how they select audits, Ho hopes they will tweak their confidential audit selection algorithm.

“Racial disparities in income are well known, and what the IRS chooses to focus on has big implications for whether audits complement, or undercut, a progressive tax system,” Ho said.

Ann Lowe: The Quiet Genius of American Couture

Lowe was born in Clayton, Alabama, into a family of gifted seamstresses. Her mother and grandmother were well-known dressmakers who created exquisite gowns for women in the area. By the time Lowe was a young girl, she was already showing extraordinary talent — cutting, sewing, and decorating fabric with a skill that far exceeded her age. When her mother died unexpectedly, Lowe – only 16 years old then – took over her mother’s sewing business, completing all the orders herself.

Ann Cole Lowe, born Dec.14, 1898, was a pioneering American fashion designer whose extraordinary talent shaped some of the most widely recognized and celebrated gowns in U.S. history.

Although she designed dresses for society’s wealthiest families and created masterpieces worn at historic events, Lowe spent much of her life in the shadows — uncredited, underpaid, yet unmatched in skill. Today, she is celebrated as one of the first nationally recognized African American fashion designers and a true visionary in American couture.

In 1917, Lowe moved to New York City to study at the S.T. Taylor Design School. Although she was segregated from White students and forced to work separately, she, of course, excelled, graduating earlier than expected. Her instructors quickly recognized that her abilities were far above the typical student, especially her skill in hand-sewing, applique, and intricate floral embellishment – techniques that would become her signature.

Throughout the 1920s and 1930s, she designed gowns for high-society women in Florida and New York, operating boutiques and working for prestigious department stores. Her reputation for craftsmanship, originality, and elegance grew increasingly. She was known for creating gowns that moved beautifully, featured delicate hand-made flowers, and looked sculpted rather than sewn. Many wealthy clients specifically requested “an Ann Lowe gown” for weddings, balls, and galas.

Her most famous creation came in 1953: the wedding gown worn by Jacqueline Bouvier when she married Massachusetts Sen. John F. Kennedy. The dress – crafted from ivory silk taffeta with dozens of tiny, pleated rosettes – became one of the most photographed bridal gowns in American history. Despite this achievement, Lowe received no public credit at the time. When a flood destroyed her completed gowns 10 days before the wedding, she and her seamstresses worked day and night to remake everything – at her own expense. Her dedication and perfectionism never wavered.

She eventually opened “Ann Lowe Originals,” her own salon on New York’s Madison Avenue. She served clients such as the Rockefellers, DuPonts, Vanderbilts, and actresses like Olivia de Havilland. Yet even with her wealthy clientele, she struggled financially, often undercharging because she wanted every dress to be perfect, even if it meant losing money.

Lowe’s contributions were finally recognized later in life. Today, her exquisite gowns are preserved in museums, including the Smithsonian National Museum of African American History and Culture and the Metropolitan Museum of Art.

In the last five years of her life, Lowe lived with her daughter Ruth in Queens, N.Y. She died at her daughter’s home on Feb. 25, 1981, at the age of 82, after an extended illness.

San Francisco-based BRIDGE Housing and its president and CEO, Ken Lombard, have been named among the nation’s housing industry standouts, earning two of the top prizes at the 2025 Multi-Housing News Excellence Awards.

BRIDGE Housing was named Development Company of the Year, while Lombard received Executive of the Year, recognition that places the nonprofit affordable housing provider alongside leading national developers of both affordable and market-rate housing.

The awards were announced in New York for the accomplishments achieved during 2024.

Multi-Housing News is one of the industry’s most respected publications. Award winners are selected by a panel of housing professionals, including multifamily developers, architects, and owners.

“BRIDGE Housing is deeply honored to be recognized by Multi-Housing News and our industry peers,” Lombard said. “These awards are a testament to the high-impact, mission-driven work by BRIDGE’s exceptional team to deliver quality affordable housing and support services that empower residents to improve their lives.”

In 2024, BRIDGE significantly expanded its footprint across California, Oregon, and Washington. That momentum continued into 2025, with portfolio growth of 9%, including the addition of nine new communities and 1,187 new or acquired affordable housing units. The nonprofit also added three new projects to its development pipeline as it nears a portfolio of 16,000 units.

The growth reflects a broader strategy aimed at accelerating both acquisitions and ground-up development, supported by partnerships with major financial institutions and innovative capital markets strategies. BRIDGE has also emphasized high-quality design and deep community engagement as central elements of its approach.

BRIDGE became the first affordable housing developer to issue tax-exempt construction bonds for one of the largest affordable housing projects in Portland, Ore., leveraging its strong credit rating.

Earlier this year, the nonprofit launched the BRIDGE Housing Impact Fund, with a goal of investing $1 billion to preserve and create affordable housing. It also closed on $175 million in taxable general-obligation bonds after increasing the offering in response to strong investor demand.

The company’s performance also underscores the role of Lombard, who has led BRIDGE since 2021 and was honored individually for his leadership.

Under Lombard’s tenure, BRIDGE has built a new leadership team with experience drawn from both the nonprofit and private sectors, with a particular focus on what the organization describes as efforts to “break the status quo,” especially in affordable housing finance. Those initiatives have helped reduce capital and construction costs, strengthen relationships with institutional investors, and expand resident support services.

Today, BRIDGE Housing serves more than 33,000 residents across 139 communities on the West Coast.

“Ken has dedicated his career to innovative real estate solutions that improve the quality of life in underserved neighborhoods,” said Kenneth Novack, chair of BRIDGE Housing’s board of directors. “His visionary leadership and the work of our incredible team have positioned BRIDGE for long-term growth that will extend our impact throughout the West Coast.”

Founded in 1983, BRIDGE Housing has helped create more than 23,000 affordable homes with a total development cost of $6 billion.

The City of Oakland announced this week that it is successfully moving forward on the sale of $334 million of General Obligation bonds, a milestone that will provide the city with capital funding for city departments to deliver paved roads, restored public facilities, and investments in affordable housing.

“Oakland is on the move and building momentum with this bond sale,” said Oakland Mayor Barbara Lee. “We are reviving access to funding for paving our streets, restoring public facilities we all use and depend upon, and investing in affordable housing for our community, all while maintaining transparency and fiscal discipline.”

“These bonds represent our city’s continued commitment to sound financial management and responsible investment in Oakland’s future,” said Lee.

“Together, we are strengthening our foundation for generations to come,” she said. “I’m grateful to our partners in the City Council for their leadership and support, and to City Administrator Jestin Johnson for driving this process and ensuring we brought it home.”

According to the city, $285 million of the bonds will support new projects and $49 million of the bonds will refund existing bonds for debt service savings.

Oakland issued the Measure U bonds on Dec. 4 after two years of delays over concerns about the city’s financial outlook. They all sold in less than a week.

The new money bonds will pay for affordable housing, roadway safety and infrastructure improvements, and renovations to parks, libraries, senior centers, and other public facilities under the city’s Measure U Authorization.

Citywide paving and streetscape projects will create safer streets for Oaklanders. Additionally, critical facilities like the East Oakland Senior Center and San Antonio Park will receive much-needed renovations, according to the city.

Some of the projects:

$50.5 million – Citywide Street Resurfacing
$13 million – Complete Streets Capital Program
$9.5 million – Curb Ramps Program
$30 million – Acquisition & Preservation of Existing Affordable Housing
$33 million – District 3: Mandela Transit-Oriented Development
$28 million – District 6: Liberation Park Development
$3 million – District 5: Brookdale Recreation Center Capital Project
$1.5 million – District 1: Oakland Tool Lending Library (Temescal Branch Library)
$10 million – District 3: Oakland Ice Center

“I recognize that many naysayers said we couldn’t do it,” said Johnson. “Well, you know what? We’re here now. And we’re going to be here next year and the year after. The fact is we’re getting our fiscal house in order. We said we were going to do it — and we’re doing it.”

Investors placed $638 million in orders for the $334 million of bonds offered by the City. There was broad investor demand with 26 separate investment firms placing orders. The oversubscription ultimately allowed the city to lower the final interest rates offered to investors and reduce the city’s borrowing cost.

“The oversubscription ultimately allowed the City to lower the final interest rates offered to investors and reduce the City’s borrowing cost,” said Sean Maher, the city’s communications director.

“The Oakland City Council worked closely with the administration to both advance the bond issuance process and ensure that the community had a clear understanding of the City’s timeline and approach,” said Councilmember at-Large Rowena Brown.

“In September, the City Council took unanimous action to authorize the Administration to move forward with the bond sale because these funds are essential to delivering the very improvements our communities have long asked for – safer streets, restored public facilities, and expanded affordable housing,” she said.

Continuing, Brown said, “I want to extend my sincere thanks to City Administrator Jestin Johnson, Finance Director Bradley Johnson, and Mayor Barbara Lee for their leadership, diligence, and steady guidance throughout the City’s bond sale efforts.

“Navigating complex market conditions while keeping Oakland’s long-term infrastructure needs front and center is no small task, and this moment reflects tremendous professionalism and persistence,” she said.

Moody’s gave the city an AA2 rating on the bonds, its third-highest rating, which it gives to high-quality investment-grade securities.

There was both a tax-exempt portion and a taxable portion for the bond offering, reflecting the various uses of the bond proceeds, according to a statement released by the city.

The $143.5 million of tax-exempt bonds have a 30-year final maturity and received an all-in borrowing cost of 3.99%. The $191 million of taxable bonds have a 24-year final maturity and received an all-in borrowing cost of 5.55%.

The $49 million in tax-exempt bonds that refinance existing obligations of the City resulted in $5.6 million of debt service savings for taxpayers through 2039, or $4.7 million on a present value basis.

Mayor Lee said that, based on her experience serving on the House Financial Services Committee of the U.S. Congress for more than 10 years, city staff has done an exemplary job.

“I have witnessed many cities go to the bond market throughout the years,” she said. “I can tell you with certainty that Oakland’s team is remarkable, and our residents should be proud of their reputation, their competence, and their deep knowledge of this very sophisticated market.”

Looking ahead to the final sale of the bonds, according to the city press statement, pricing marks the point at which the City and investors locked in the final dollar amounts, interest rates, and other key terms of the bond sale. This stage is commonly referred to as the sale date. At pricing, no funds are exchanged. The actual delivery of bonds and receipt of monies occurs at closing, which is scheduled within the next two weeks.

Capital projects receiving this funding will proceed on individual timelines based on their individual conditions and needs. At the time of closing, funding will be immediately available to those projects.
