IRS Shutdown May Delay October 15 Tax Filings and Refunds

As Congress struggles to reach a funding agreement, the federal government shutdown is beginning to ripple through the U.S. tax system. For most taxpayers, the effects might seem distant until they file their returns this month. But for the millions who filed for an extension until October 15, the timing couldn’t be worse.

With the IRS running on limited staff and resources, even small disruptions could lead to refund delays, communication breakdowns, and compliance headaches that carry financial consequences.

What Happened

With the federal government partially shut down, the IRS is operating with minimal staff and restricted funding.

While core systems remain active, processing functions for extended filers who postponed their 2024 returns to the October 15 deadline are now facing potential disruptions.

According to Investopedia (Oct. 6, 2025), taxpayers filing during the extension window may see longer turnaround times for return processing, refunds, and notices.

Why It Matters

For CPAs, tax attorneys, and business owners, the timing could not be worse:

• Extension filers at risk: Those who filed Form 4868 expecting a smooth October submission could now experience backlogs.

• Refunds delayed: Refunds for both individual and corporate taxpayers might take weeks longer, affecting year-end cash flow.

• IRS correspondence stalled: Requests for transcripts, penalty abatements, or amended returns could sit idle until normal operations resume.

• Compliance exposure: Delays could increase the risk of missing response deadlines for notices or audits, even when taxpayers act in good faith.

  
  

What Tax Professionals Should Do Now

• File as early as possible. Do not wait until October 15; aim to file before contingency staffing runs out.

• Monitor IRS operational updates. The IRS regularly posts its contingency plan status on IRS.gov.

• Advise clients on refund expectations. Manage expectations around processing timelines and potential delays in direct deposits or paper checks.

• Document communications. Keep a record of client submissions, notices, and responses to safeguard against timing disputes.

  
  

What’s Next?

If the shutdown continues into mid-October, IRS backlogs could spill over into the 2026 filing season, creating compounding administrative delays. Congressional negotiations will ultimately determine when normal operations resume, but tax professionals should prepare for a slow return to full service.
