For decades, the Internal Revenue Service has operated as one of the federal government’s most sprawling and consequential bureaucracies, touching the financial lives of virtually every American household and business. Now, under the weight of unprecedented workforce reductions driven by the Department of Government Efficiency — Elon Musk’s cost-cutting initiative within the Trump administration — the agency is entering what may be its most diminished state in modern history. The implications for the 2026 tax filing season could be severe, with experts warning of delayed refunds, degraded customer service, and a system buckling under the strain of doing more with dramatically less.
The scale of the IRS workforce reduction is staggering. According to Business Insider, the agency has already shed thousands of employees through a combination of voluntary buyouts, layoffs, and the non-renewal of contracts. The cuts have accelerated in recent months, with DOGE-led initiatives targeting positions across nearly every division of the agency — from taxpayer assistance centers to compliance enforcement to information technology. Former IRS officials and tax professionals are sounding alarms that the 2026 filing season, which will process returns for the 2025 tax year, could see significant disruptions that hit ordinary taxpayers squarely in their wallets.
A Workforce Gutted: The Numbers Behind the IRS Exodus
The IRS employed roughly 90,000 workers at its peak staffing levels following the passage of the Inflation Reduction Act in 2022, which allocated approximately $80 billion in new funding to the agency over a decade. That legislation was designed to modernize the IRS’s aging technology systems, improve customer service, and bolster enforcement against wealthy tax evaders. But much of that funding has since been clawed back or frozen by congressional Republicans and the Trump administration, and the workforce gains have been reversed at a breathtaking pace. Estimates suggest the agency could lose between 20,000 and 40,000 positions by the time the 2026 filing season begins in January, depending on the pace of additional cuts.
The reductions have not been surgical. As Business Insider reported, many of the employees let go were recently hired workers brought on specifically to address the IRS’s chronic understaffing problems. These included customer service representatives who had helped bring phone wait times down from an average of 28 minutes during the 2022 filing season to under five minutes in more recent years. With those workers gone, tax professionals expect phone wait times to balloon once again, leaving millions of taxpayers unable to get answers to basic questions about their returns, refund status, or notices they’ve received from the agency.
Refund Delays: The Tangible Cost of a Leaner Agency
For most Americans, the tax refund is the single largest financial transaction of the year. The IRS issued more than 100 million refunds during the 2024 filing season, with an average refund hovering around $3,100. Those payments serve as a critical financial lifeline for working families — used to pay down debt, cover medical bills, repair vehicles, or simply keep the lights on. Any systemic delay in processing those refunds ripples through the broader consumer economy. Retailers, auto dealers, and service providers all feel the effects when refund checks are late.
Tax professionals are already warning clients to prepare for a slower process. The National Taxpayer Advocate, an independent office within the IRS that serves as a watchdog for taxpayer rights, has previously flagged understaffing as the agency’s most persistent and damaging problem. In past years when IRS staffing dipped — notably during the pandemic era — refund processing times stretched from the typical 21-day window to six weeks or longer for many filers, and paper returns sometimes sat in trailers for months before being opened. The fear among industry insiders is that the 2026 season could echo or even exceed those pandemic-era backlogs, not because of a public health crisis, but because of deliberate policy choices to shrink the agency.
Enforcement Takes a Hit: Who Benefits When the IRS Can’t Audit?
The workforce reductions extend well beyond customer service. The IRS’s enforcement division — responsible for auditing returns, pursuing tax cheats, and collecting unpaid taxes — has been particularly hard hit. This is consequential because every dollar spent on IRS enforcement historically generates between $5 and $12 in recovered revenue, according to estimates from the Congressional Budget Office and the Treasury Department. Cutting enforcement staff doesn’t just weaken the agency; it actively costs the federal government money by allowing billions in owed taxes to go uncollected.
The beneficiaries of reduced enforcement capacity are disproportionately high-income individuals and large corporations with complex tax structures. The IRS has long acknowledged that auditing wealthy taxpayers and multinational companies requires specialized expertise and significant resources — exactly the kind of capacity that is being eroded. Meanwhile, lower-income taxpayers who claim the Earned Income Tax Credit continue to face relatively high audit rates because those audits are simpler and cheaper to conduct. The result is a system that, by default, becomes more regressive as it shrinks — scrutinizing the working poor while letting sophisticated tax avoidance by the wealthy go unchecked.
Technology Modernization Stalls as IT Staff Depart
Perhaps the most underappreciated dimension of the IRS staffing crisis is its impact on technology modernization. The agency still relies on systems built in the 1960s — legacy code written in COBOL that few living programmers fully understand. The Inflation Reduction Act funding was supposed to finally drag the IRS into the 21st century, with investments in digital filing, automated processing, and improved fraud detection. Many of the IT professionals hired to execute that modernization have now been let go or have left voluntarily amid the uncertainty.
Without continued investment in technology, the IRS remains vulnerable to the same cascading failures that plagued it during the COVID-19 pandemic, when paper returns piled up and digital systems couldn’t handle the volume of amended filings and stimulus payment reconciliations. Tax preparation firms including H&R Block, Intuit’s TurboTax, and Jackson Hewitt have all invested heavily in their own digital infrastructure, but their systems ultimately depend on a functioning IRS backend to process returns and issue refunds. If the agency’s technology degrades further, even electronically filed returns could face processing delays — a scenario that would affect the vast majority of filers.
Political Crosscurrents and the Battle Over the IRS’s Future
The debate over IRS staffing levels is deeply partisan. Republicans have long argued that the agency is bloated, overreaching, and in need of significant reform. The decision to claw back IRS funding has been framed as a necessary corrective to what conservatives view as the Biden administration’s attempt to weaponize the tax agency against ordinary Americans. Proponents of the cuts argue that a leaner IRS will be forced to become more efficient and that technology can substitute for human workers in many routine functions.
Democrats and tax policy experts counter that the math simply doesn’t work. Processing 150 million individual tax returns, handling tens of millions of phone calls, conducting audits, and managing correspondence requires a massive human workforce regardless of technological improvements. Former IRS Commissioner Charles Rettig, who served under the first Trump administration, has himself acknowledged that the agency was dangerously understaffed even before the current round of cuts. The nonpartisan Government Accountability Office has repeatedly listed IRS modernization and staffing as a high-risk area for the federal government.
What Taxpayers Should Do Now to Prepare for a Turbulent Season
Given the expected disruptions, tax professionals are urging filers to take proactive steps well before the 2026 filing season opens. Filing electronically and opting for direct deposit remains the single most effective way to minimize refund delays, as paper returns require manual processing by IRS employees — a resource that will be in critically short supply. Taxpayers should also ensure their records are meticulous, since errors on returns will be far harder to resolve when customer service lines are overwhelmed and correspondence processing is backlogged.
For those with more complex tax situations — small business owners, freelancers, investors, and individuals with foreign income — the advice is even more pointed: engage a qualified tax professional early, double-check every figure, and be prepared for longer-than-usual wait times on any IRS interactions. The Taxpayer Advocate Service, which helps resolve disputes and hardship cases, is itself expected to be strained, meaning that taxpayers who encounter problems may have fewer avenues for relief. The 2026 filing season is shaping up to be a stress test for an agency that, by design, will have fewer resources than at any point in recent memory. For the roughly 160 million Americans who file tax returns each year, the consequences will be anything but abstract.
