The News: IRS Announces a Major Compliance Hiring Push

On October 23, 2026, Bloomberg Tax reported that IRS Chief of Compliance Jarod Koopman announced at the UCLA Tax Controversy Conference that the agency is hiring roughly 1,000 workers for its Small Business/Self-Employed (SB/SE) and Large Business and International (LB&I) divisions — the two divisions responsible for auditing individuals, small businesses, partnerships, and corporations. The agency is simultaneously hiring approximately 175 workers for its Criminal Investigation unit. A follow-up report published today, October 28, 2026, confirms the private sector is closely watching the move for signs of a sustained enforcement shift.

For taxpayers who have been quietly living with unfiled tax returns, unresolved IRS notices, or growing tax debt, this announcement deserves your full attention. The window created by the agency's workforce disruption is closing.

How the IRS Got Here: A Workforce That Shrank by a Quarter

To understand why this hiring wave matters, you need to understand what preceded it. Earlier this year, the IRS lost roughly a quarter of what had been a workforce of approximately 100,000 employees — largely due to voluntary departures incentivized by the Department of Government Efficiency (DOGE). IRS CEO Frank Bisignano has indicated he is comfortable with the agency's current level of approximately 75,000 employees, meaning this new hiring is targeted and strategic — not a return to the prior staffing high-water mark.

The losses were not evenly distributed across experience levels. According to the Treasury Inspector General for Tax Administration (TIGTA), nearly 40% of the IRS employees who left the agency had more than 11 years of experience — the kind of seasoned revenue agents and collections officers who know how to build a case, negotiate installment agreements, and move a levy or lien through the system efficiently.

The downstream effects on enforcement were measurable and significant. A TIGTA report published in August 2026 found that individual audit starts fell 30% in fiscal year 2025, including a 27% decline among taxpayers earning more than $400,000, as staffing levels dropped. The same report found that the IRS's examination and collection workforce — the people who audit returns and pursue unpaid balances — shrank by approximately 27% between the end of fiscal year 2024 and the end of fiscal year 2025.

That gap created a period of reduced enforcement pressure for many taxpayers. That period is now ending.

AI Is Already Filling the Gap — And Has Been for Months

Here is what many taxpayers miss: the IRS did not simply slow down and wait for new hires. Instead, the agency leaned aggressively into automation. IRS officials have publicly stated the agency is relying on artificial intelligence — which internal leadership has called "super intelligence" — to help fill the enforcement gap left by workforce losses.

The IRS reported having more than 100 active AI projects as of early 2025, with more than two dozen specifically focused on tax compliance and enforcement. These systems cross-reference third-party data — W-2s, 1099s, K-1s, financial institution reports, real estate transactions — against filed returns (and the absence of filed returns) at a scale no human workforce could match.

What this means practically: the IRS has been generating compliance flags and identifying non-filers and underreporters at high volume throughout the staffing drought. What it lacked was the human capacity to fully work those cases. The new hires are the agency's answer to that bottleneck. As revenue agents and collections officers are brought on and trained, the backlog of AI-identified cases will be worked — and that work will accelerate.

Who Is the IRS Hiring, and Who Does It Affect?

The specific divisions receiving the bulk of the new workers tell you a great deal about enforcement priorities:

• Small Business/Self-Employed (SB/SE): This division covers sole proprietors, S-corporations, partnerships, and individual taxpayers with more complex returns — including gig workers, freelancers, landlords, and business owners. SB/SE revenue agents conduct audits. SB/SE revenue officers handle collection — they're the ones who issue bank levies, wage garnishments, and federal tax liens. If you owe the IRS and haven't made arrangements, revenue officers are the people who show up.
• Large Business and International (LB&I): This division covers corporations and high-net-worth individuals with international holdings or complex partnership structures. If you have significant assets, offshore accounts, or equity stakes in pass-through entities, LB&I is the relevant division.
• Criminal Investigation (CI): CI agents investigate potential tax crimes — willful non-filing, tax evasion, fraudulent returns, and money laundering. CI's 175 new hires signal that the agency's criminal referral pipeline remains active, even as the civil side rebuilds. Koopman noted that some CI agents had been detailed to support other federal law enforcement priorities — including immigration and local crime efforts in certain cities — but emphasized those agents continued to maintain their IRS workload.

Tax professionals who work directly on IRS collection cases have noted they are waiting to see whether the agency will post additional revenue agent and collections officer positions — the roles that most directly affect taxpayers with open balances and active collection matters.

The Compliance Strategy Has Also Changed

Beyond headcount, the IRS's enforcement approach itself is being restructured. Koopman stated that the IRS's compliance strategy had not been updated since 2017 and lacked metrics to evaluate whether revenue agents were effectively collecting taxes owed. The new approach is designed to be data-driven, coordinated across divisions, and leaning on automation and analytics to direct human attention to the highest-value and highest-risk cases.

What that means for taxpayers: the IRS is not simply returning to how enforcement worked before the workforce reduction. It is rebuilding with a sharper selection process. Automated case selection means the agency is increasingly likely to pursue taxpayers where the data already tells a clear story — high income with no filed return, a 1099 that doesn't match a return, a business with payroll records but no employment tax deposits.

What This Means If You Have Unfiled Returns

Non-filing is one of the highest-risk positions a taxpayer can be in right now. Here is why:

• The IRS receives copies of every W-2, 1099-NEC, 1099-K, 1099-INT, 1099-DIV, and K-1 issued to you. Its matching systems already know, in most cases, approximately how much you earned.
• When you don't file, the IRS can prepare a Substitute for Return (SFR) under Internal Revenue Code § 6020(b). An SFR uses the income information the IRS has, but it claims no deductions, no credits, and no filing status advantages beyond single. The resulting assessment is almost always higher than what you would actually owe on a properly prepared return.
• Once an SFR assessment is issued, the IRS can immediately begin the collection process — notices, liens (IRC § 6321), levies (IRC § 6331) — without waiting for you to file.
• The statute of limitations on IRS collection (generally 10 years from the date of assessment under IRC § 6502) does not begin to run on an unfiled year until the IRS makes an assessment. If you never file and the IRS never issues an SFR, the IRS could theoretically pursue that year indefinitely. If the IRS files an SFR against you, the 10-year clock starts — but it starts from a much higher balance than you likely actually owe.

The practical takeaway: filing delinquent returns voluntarily — even late — almost always produces a better result than waiting for the IRS to file for you. It also demonstrates good faith, which matters in installment agreement negotiations, penalty abatement requests, and Offer in Compromise applications.

What This Means If You Already Owe the IRS

If you have an existing IRS balance — whether from a prior audit, an SFR assessment, unpaid estimated taxes, or payroll taxes — the rebuilding enforcement workforce means collection activity on dormant or slow-moving cases is likely to increase over the coming months. Here is what you should know:

• Currently Not Collectible (CNC) status is reviewed periodically. If your financial situation has improved since you were placed in CNC, the IRS may remove that status and resume collection activity once it has the capacity to review cases again.
• Installment agreements in default — for example, because you missed payments or incurred new tax debt — can be reinstated, but only if you act before the IRS files a new Notice of Federal Tax Lien or issues a levy. Waiting until a levy lands on your bank account or wages dramatically narrows your options.
• The Collection Statute Expiration Date (CSED) under IRC § 6502 is generally 10 years from assessment. If your oldest debt is approaching that date, the IRS is aware of it and may accelerate action. Certain actions — like filing for bankruptcy or submitting an Offer in Compromise — toll the statute and extend the IRS's collection window, so these calculations require careful analysis.
• Offers in Compromise (OIC) under IRC § 7122 and Form 656 allow eligible taxpayers to settle for less than the full balance, based on reasonable collection potential. Processing times for OICs can be substantial, and the IRS's ability to process them depends on staffing. Submitting a well-prepared OIC now, before the enforcement queue fully fills, may be strategically advantageous.

The Enforcement Window: What History Tells Us

This is not the first time the IRS has cycled through a staffing contraction followed by a rebuilding phase. Each prior cycle produced a predictable pattern: a period of reduced enforcement activity, followed by a hiring and training ramp-up, followed by a surge in notices, audits, and collection actions as the new workforce became operational. The ramp-up typically takes 12 to 24 months — new revenue agents and revenue officers require substantial training before they handle cases independently.

That timeline matters. The taxpayers who take action during the ramp-up — who file delinquent returns, set up payment arrangements, or submit resolution applications — tend to have more negotiating room and fewer coercive collection actions to contend with than those who wait until the rebuilt enforcement pipeline is fully operational.

Specific Steps to Consider Right Now

If you have unfiled returns, unresolved IRS debt, or pending notices, here is a practical checklist:

• Pull your IRS transcript. Use the IRS's Get Transcript tool (online or by mail) to see exactly what years are unfiled, what assessments are on record, and whether any collection action has been initiated. Your transcript tells you where you stand before you decide what to do next.
• File delinquent returns as quickly as possible. Even if you cannot pay the balance due, filing stops the failure-to-file penalty (generally 5% of the unpaid tax per month under IRC § 6651(a)(1), up to 25%) from continuing to accrue. The failure-to-pay penalty (0.5% per month under IRC § 6651(a)(2)) is much lower and continues until the balance is paid — but stopping the larger failure-to-file penalty saves real money.
• Respond to any pending IRS notices immediately. An IRS notice is not just paperwork — it is often a clock. LT11/Letter 1058 starts a 30-day window before the IRS can levy without further notice. CP2000 underreporter notices require a response within the stated deadline. Missing these deadlines forfeits your right to challenge the IRS's proposed adjustment without paying first and filing a refund claim.
• Evaluate your resolution options with a qualified professional. The right resolution strategy — installment agreement, CNC, OIC, penalty abatement under IRC § 6404 or first-time abatement policy, innocent spouse relief under IRC § 6015 — depends entirely on your specific financial circumstances, the age of the debt, and the types of taxes owed. These are not decisions to make without professional guidance.
• Do not ignore enforcement signals. If you have received a Notice of Federal Tax Lien, a final notice of intent to levy, or a visit from a revenue officer, you are in active collection — not the preliminary stages. The time to act is now, not after a bank account is frozen or a paycheck is garnished.

Bottom Line

The IRS's announcement that it is hiring approximately 1,000 civil enforcement workers and 175 Criminal Investigation agents — on top of its already-active AI compliance systems — is a clear signal that the reduced enforcement period following the 2025 workforce contraction is drawing to a close. Taxpayers with unfiled returns, unresolved balances, or dormant IRS collection cases have a narrowing window to get ahead of the rebuilt enforcement pipeline on their own terms.
