Donor States vs. Recipient States: Where Does Your Federal Tax Dollar Go?
Some states send Washington more money than they receive, while others receive considerably more federal spending. Here’s what “donor state” really means—and why the numbers don’t necessarily measure government dependency.

Every year, Americans send trillions of dollars to Washington through income taxes, payroll taxes, corporate taxes and other federal revenues. The federal government then sends trillions back across the country through Social Security, Medicare, Medicaid, military spending, federal salaries, contracts, grants, infrastructure projects and dozens of other programs.
But the money doesn’t necessarily return to the states in the same proportions in which it was collected.
That’s where the terms “donor state” and “recipient state” come in.
What Is a Donor State?
Simply put, a donor state sends more money to the federal government than it receives back in federal spending.
Imagine taxpayers and businesses in a state contribute $100 billion to the federal government during a year. If federal spending within that state totals only $80 billion, the state has effectively contributed $20 billion more to the federal government than it received.
A recipient state experiences the opposite: federal expenditures within the state exceed the amount collected there in federal revenue.
These aren’t official federal government classifications, however. They’re terms commonly used by researchers analyzing the flow of money between individual states and Washington.
Only Three Donor States in 2023?
According to an August 2025 analysis from the Rockefeller Institute of Government using preliminary federal fiscal year 2023 data, only three states had negative balances—meaning they contributed more federal revenue than they received in federal expenditures.
Those states were:
New Jersey: approximately $18.9 billion more contributed than received.
Massachusetts: approximately $6.8 billion more contributed than received.
Washington: approximately $54 million more contributed than received.
At first glance, that might suggest nearly every other state depends financially on those three states.
The reality is considerably more complicated.
COVID Changed the Numbers
Historically, several wealthy states—including California and New York—have frequently appeared on the donor side of the equation.
The enormous federal response to the COVID-19 pandemic disrupted that pattern.
Trillions of dollars in extraordinary federal spending flowed into states through stimulus payments, business assistance, unemployment programs, healthcare funding, state and local government assistance and other programs.
Even after the emergency phase of the pandemic ended, some of those expenditures continued influencing federal balance-of-payments calculations.
That’s one reason examining a single year can produce a misleading picture.
California: Recipient Today, Historical Donor
California provides perhaps the best example.
In fiscal year 2023, California technically received slightly more federal spending than it contributed—approximately $342 more per person.
But look at the longer-term numbers and the picture changes.
Using a nine-year average that excludes COVID-related spending, Rockefeller Institute researchers calculated California’s average balance at approximately negative $29 billion.
In other words, over a more typical period, California has historically contributed substantially more to the federal government than it received.
Its enormous economy, high incomes and large number of taxpayers generate tremendous amounts of federal revenue.
New York Tells a Similar Story
New York has also historically ranked among America’s major donor states.
Yet in 2023, New York had a positive federal balance of approximately $13.3 billion, receiving roughly $1.04 in federal expenditures for every $1 it contributed.
Researchers attributed much of the change from New York’s historical pattern to lingering pandemic-era federal expenditures.
As those programs disappear from the calculations, New York could return to its traditional position as a donor state.
Arizona Is a Net Recipient
Arizona presents a different picture.
Over the Rockefeller Institute’s nine-year analysis, Arizona averaged a positive federal balance of approximately $44.5 billion.
Even after excluding COVID-related spending, Arizona’s average remained positive at roughly $35.3 billion.
That means federal expenditures flowing into Arizona have substantially exceeded federal revenue collected from the state.
But that doesn’t mean Arizona simply receives tens of billions of dollars in “welfare.”
Federal spending includes far more than public assistance.
Arizona hosts military installations, federal lands and agencies, defense and aerospace operations, veterans programs and a significant retiree population receiving Social Security and Medicare.
All of those expenditures count toward the state’s federal balance.
Texas Receives More Than It Sends
Texas also had a substantial positive balance in 2023.
Federal expenditures exceeded revenues collected from Texas by approximately $80 billion, making it one of the country’s largest net recipients in total dollars that year.
Again, the number needs context.
Texas is home to major military installations, NASA operations, defense contractors, federal infrastructure projects and millions of Social Security and Medicare recipients.
Those federal dollars all count as money flowing back into the state.
The Surprising Leader: Virginia
If recipient-state status simply meant dependency on federal welfare programs, Virginia would seem like an unlikely candidate to lead the country.
Yet Virginia recorded the nation’s largest positive federal balance in 2023 at approximately $145.4 billion.
Why?
Location.
Virginia sits next to Washington, D.C., and contains an enormous concentration of federal employees, military installations, government contractors and defense spending.
Neighboring Maryland ranked second with a positive balance of approximately $81.1 billion.
The numbers illustrate why federal balance-of-payments statistics should not automatically be interpreted as measurements of welfare dependency.
A recipient state isn’t necessarily a “welfare state.” Federal expenditures include Social Security, Medicare, military installations, defense contracts, federal salaries, research, infrastructure, grants and other programs.
Where Does the Federal Money Actually Go?
Federal expenditures flowing into a state can include:
- Social Security
- Medicare and Medicaid
- Military bases and personnel
- Defense contracts
- Federal employee salaries
- Highway and transit funding
- Scientific and university research
- Agricultural programs
- Veterans benefits
- Disaster assistance
- Federal grants
- Infrastructure projects
- Federal agency operations
A state containing a large military installation, federal laboratory or government agency can therefore receive billions of federal dollars without that money having anything to do with traditional public assistance programs.
Why Wealthier States Often Become Donors
Federal income taxes are progressive.
People with higher incomes generally pay a larger percentage of their income in federal income taxes.
States containing large concentrations of high-income households and highly profitable companies can consequently generate enormous amounts of federal revenue.
That helps explain why states such as California, New York, New Jersey and Massachusetts have historically appeared frequently among net contributors.
The federal government doesn’t earmark the taxes collected in California exclusively for California.
The money enters the national treasury and helps finance programs throughout the United States.
In that sense, federal taxation intentionally redistributes resources geographically as well as economically.
So Are Donor States “Subsidizing” Recipient States?
In a broad accounting sense, yes.
Federal revenue collected disproportionately from some states helps finance federal expenditures occurring elsewhere.
But describing the relationship simply as one state “paying for” another leaves out important context.
Federal spending follows national priorities rather than state borders.
A Navy base in Virginia protects the entire country. NASA facilities in Texas conduct missions funded by taxpayers nationwide. Social Security benefits paid to a retiree in Arizona may reflect payroll taxes that person paid while working decades earlier in California, Illinois or New York.
Americans and businesses also move between states throughout their lives.
The federal system was never designed to ensure that every dollar collected within a state’s borders would eventually return to that same state.
The Bigger Picture
The donor-state debate is often used as political ammunition, particularly when politicians argue about which parts of the country are supporting others.
The numbers are real, but they require context.
A state can move from donor to recipient status because of a recession, natural disaster, military spending, demographic changes, infrastructure investments or extraordinary events such as the COVID-19 pandemic.
That’s why examining several years of data generally tells us more than looking at a single year.
Ultimately, the donor-versus-recipient calculation reveals something fundamental about the United States:
Federal taxes don’t remain where they’re collected.
They become part of a national pool used to fund programs, obligations and investments across all 50 states.
And depending on where you live, your state may be putting more into that pool—or taking more out—at any particular moment.

Food Truths
The Truth About the “Chemical” in McDonald’s Burger Buns: Should Consumers Be Concerned?
What’s in the Burger Buns:The “yoga mat chemical” controversy changed how consumers view food additives. Here’s what azodicarbonamide is, why McDonald’s removed it, and what the science actually says.

For years, headlines and social media posts have warned consumers about a so-called “yoga mat chemical” found in hamburger buns served by major fast-food chains. The claims sparked widespread concern, prompted petitions, and eventually led several restaurant companies—including McDonald’s—to change their recipes.
But what was the chemical, and is there actually a health risk today?
What Was the Controversial Ingredient?
The ingredient at the center of the controversy was azodicarbonamide (ADA), a chemical used as a dough conditioner. It helped improve the texture of bread, making dough easier to handle and producing softer, more consistent buns.
Ironically, the same compound is also used in manufacturing certain foamed plastics, including some yoga mats and shoe soles. That connection gave rise to the viral nickname, “the yoga mat chemical.”
While the comparison was technically accurate, it also lacked important context. Food-grade azodicarbonamide and industrial applications are very different, and many chemicals have multiple uses across industries.
Why Did People Become Concerned?
The concern wasn’t simply that ADA was used in food. Scientists focused on what happens during baking.
When bread is baked, most azodicarbonamide breaks down into other compounds. Some laboratory studies involving animals raised questions about one of these breakdown products, called semicarbazide (SEM), when administered in high doses.
Those findings prompted some countries to take a more cautious regulatory approach.
Why Is It Banned in Some Countries?
The European Union and Canada do not permit azodicarbonamide as a flour treatment agent. Their food safety policies often follow the precautionary principle, removing ingredients when safer alternatives exist or when scientific uncertainty remains.
In contrast, the U.S. Food and Drug Administration has determined that azodicarbonamide is safe when used within approved limits.
These differing regulations don’t necessarily mean one side believes the ingredient is dangerous while the other believes it is harmless. Instead, they reflect different philosophies about regulating food additives.
Does McDonald’s Still Use It?
No.
McDonald’s removed azodicarbonamide from its U.S. hamburger buns in 2014 following growing consumer demand for simpler ingredient lists.
Today’s buns no longer contain the ingredient, joining a broader trend among food manufacturers to eliminate additives that have become controversial with consumers.
Are There Other Ingredients Consumers Should Know About?
Modern commercial bread still contains ingredients designed to improve freshness, texture, and shelf life.
These may include:
- Calcium propionate to prevent mold
- Ascorbic acid (Vitamin C) as a dough conditioner
- Enzymes that improve consistency
- Emulsifiers that help maintain softness
These ingredients have been evaluated by food safety agencies and are generally recognized as safe when used according to regulations.
The Bigger Health Picture
Nutrition experts generally agree that focusing on one ingredient can distract from the larger issue.
The greatest health risks associated with fast food are more closely linked to:
- High sodium intake
- Excess saturated fat
- Added sugars
- Large portion sizes
- Frequent consumption of ultra-processed foods
An occasional fast-food meal is unlikely to determine someone’s long-term health. Overall dietary patterns, physical activity, sleep, and other lifestyle factors have a much greater impact.
Consumer Awareness Is Changing the Food Industry
Whether or not an ingredient poses a measurable health risk, public concern can influence corporate decisions.
Over the past decade, many food companies have reformulated products to remove controversial ingredients, reduce artificial additives, and simplify ingredient labels. In many cases, those changes have been driven as much by consumer preferences as by regulatory requirements.
The Bottom Line
The “yoga mat chemical” story captured public attention because it combined science, food safety, and memorable marketing. While azodicarbonamide was once used in some hamburger buns, including those supplied to McDonald’s, the company removed it from its U.S. buns years ago.
Current evidence suggests consumers are better served by paying attention to their overall diet rather than worrying about a single ingredient that has already disappeared from many products.
Being an informed consumer means looking beyond the headlines, understanding the science, and recognizing that nutrition is about the complete picture—not just one ingredient.
