The IRS has fewer auditors now than it did twenty years ago, so enforcement against wealthy tax evaders has declined sharply

The short answer is no — not at the scale you might expect. The IRS has significantly reduced enforcement against high-income earners over the past decade, even as the number of millionaires in the United States has grown. This is not because the agency decided to stop trying. It is because Congress has cut the IRS budget repeatedly, and the agency has had to choose where to spend its limited resources.

In 2010, the IRS had roughly 2,600 criminal investigators. By 2023, that number had fallen to around 1,800. The audit rate for millionaires has dropped even more steeply. In 2010, the IRS audited roughly 8 percent of tax returns from people earning over $1 million. By 2022, that rate had fallen to below 2 percent. For comparison, the audit rate for people earning between $25,000 and $50,000 has remained relatively stable or even increased in some years.

The reason is straightforward: auditing a millionaire's return takes months or years and requires specialized accountants and lawyers. Auditing a middle-income return takes far less time and money. With a shrinking budget, the IRS has had to make trade-offs, and it has increasingly chosen the faster cases.

Key Takeaways

  • IRS audit rates for millionaires fell from roughly 8 percent in 2010 to below 2 percent by 2022, largely because the agency's budget and staff shrank.
  • Criminal prosecution of tax crimes has also declined — the IRS brought roughly 1,500 criminal cases per year in the early 2010s and fewer than 1,000 by 2023.
  • High-income earners with complex returns involving business income, investments, and deductions face lower audit risk now than they did a decade ago.
  • The IRS has shifted enforcement toward lower and middle-income earners partly because those audits are faster and cheaper to conduct.

How budget cuts changed IRS enforcement priorities

The IRS budget has been cut in real dollars (adjusted for inflation) since 2010. In that year, the agency received roughly $13 billion in annual funding. By 2022, that had fallen to roughly $11.5 billion, even though the number of tax returns filed had grown and the complexity of the tax code had not decreased.

With less money, the IRS had to choose. Auditing a return from someone earning $40,000 might take 10 to 20 hours of staff time. Auditing a return from someone earning $5 million, with business income, investment losses, and charitable deductions, might take 200 to 500 hours spread across multiple years. The math is brutal: one complex audit costs the same as 20 simple ones.

The agency also lost experienced auditors and investigators to retirement and attrition. Replacing them takes time and training. The result is that high-income tax enforcement has become a smaller and smaller slice of what the IRS actually does.

Criminal prosecution of tax crimes has also declined

Beyond audits, the IRS Criminal Investigation division pursues people for tax fraud — deliberately hiding income, inflating deductions, or using offshore accounts to evade taxes. These cases are rare and they are becoming rarer.

In 2011, the IRS Criminal Investigation division opened roughly 2,500 cases and secured roughly 1,500 convictions. By 2023, those numbers had fallen to roughly 1,800 cases and roughly 800 convictions. The decline reflects both fewer investigators and a shift in priorities toward cases involving identity theft and refund fraud, which are easier to prove and prosecute.

A criminal tax case against a wealthy individual requires evidence of intent to defraud, not just a mistake or an aggressive interpretation of the tax code. That means the IRS must prove the person knowingly and willfully violated the law. It is a high bar, and it requires extensive investigation. With limited resources, the IRS has pursued fewer of these cases.

Why wealthy people still face some audit risk

Even though audit rates for millionaires have fallen, they remain higher than audit rates for middle-income earners. Someone earning $1 million or more is still more likely to be audited than someone earning $50,000, though the gap has narrowed.

The IRS uses computer algorithms to flag returns for audit based on patterns that suggest risk. High income alone does not trigger an audit, but certain deductions, business structures, and income sources do. A person who reports $2 million in business income but claims $800,000 in deductions, or who reports losses from a rental property year after year, is more likely to be selected than someone with straightforward W-2 income.

The IRS also pursues cases referred by whistleblowers or uncovered during investigations into other people. If someone's accountant is caught helping clients hide income, the IRS may audit that accountant's other clients. If a business is under investigation, the owners' personal returns may be examined too.

What changed between 2010 and now

The decline in high-income enforcement is not the result of a single policy change. It is the cumulative effect of budget cuts, staffing losses, and shifting priorities. Congress has not passed a major tax enforcement bill since 2010, and the IRS budget has been cut or frozen in most years since then.

In 2021 and 2022, Congress considered proposals to increase IRS funding and staffing specifically to improve enforcement against high-income earners and large corporations. The Inflation Reduction Act, passed in August 2022, included roughly $80 billion in new IRS funding over ten years, with a stated goal of improving enforcement. However, the agency has said much of that funding will go toward customer service and technology upgrades, not just enforcement.

The practical effect is that a person earning $1 million today faces a lower risk of audit than a person earning $1 million did in 2010. Whether that risk will increase in the coming years depends on how the IRS spends the new funding it has received.

The difference between audit and criminal investigation

An audit is a civil matter. The IRS examines your return, asks for documentation, and either agrees with what you reported or assesses additional tax, penalties, and interest. You can dispute the findings in Tax Court. An audit does not result in criminal charges unless the IRS discovers evidence of fraud.

A criminal investigation is different. It happens when the IRS Criminal Investigation division believes you have deliberately broken the law. Criminal cases can result in prison time, fines, and a criminal record. They are rare — the IRS pursues fewer than 1,000 criminal cases per year out of roughly 150 million returns filed.

Most people who owe back taxes will never face either an audit or a criminal investigation. The IRS focuses its limited resources on cases where the stakes are highest or the evidence is strongest.

Frequently Asked Questions

Can the IRS still audit me if I earn over $1 million?

Yes. The audit rate for high-income earners is lower than it was a decade ago, but it is still higher than the rate for middle-income earners. The IRS uses computer algorithms to flag returns with patterns that suggest risk, such as unusually high deductions or business losses. Certain industries and income sources are also flagged more often than others.

What happens if the IRS finds I owe back taxes?

The IRS will assess additional tax, plus interest calculated from the date the tax was due. If the IRS determines you made a mistake, you may also owe a penalty, typically 20 percent of the underpayment. If the IRS believes you deliberately hid income or inflated deductions, the penalty can be higher. You can dispute the findings in Tax Court.

Is it true that rich people never get caught?

No. The IRS does pursue high-income earners, and criminal convictions for tax crimes still happen. However, the number of audits and criminal cases has declined because the IRS has fewer resources. A person with a complex return involving business income, investments, and deductions is more likely to be audited than someone with straightforward W-2 income, regardless of total earnings.

What should I do if I think I owe back taxes?

Contact a tax professional or the IRS directly. The IRS has payment plans and settlement options for people who owe back taxes. If you contact the IRS before the agency contacts you, you may face smaller penalties. Waiting for the IRS to find the problem usually results in higher costs.
