How 2025–2026 tax law and IRS rule changes (credits, deductions, QOCD, SALT, SSA forms) are altering refund sizes and filing practices, plus operational impacts on processing.

As the 2025–2026 tax seasons progress, American taxpayers are navigating an unprecedented blend of historic tax law expansions and persistent operational hurdles within the IRS and state tax agencies. These sweeping changes—spanning expanded refundable credits, inflation-indexed brackets, the introduction of the Qualified Overtime Compensation Deduction (QOCD), and a temporarily raised SALT deduction cap—are materially increasing refunds for millions. At the same time, new IRS procedural updates and lingering bottlenecks in identity verification, employer certification, and state conformity are complicating filing practices and delaying refund disbursements.

This evolving tax landscape reflects not only legislative ambition to provide broader relief amid inflationary pressures but also ongoing challenges in IRS modernization and taxpayer service delivery. Understanding the latest developments, their practical impact, and strategies to navigate emerging complexities is critical—especially for refund-dependent, paycheck-to-paycheck households who rely heavily on timely tax refunds for financial stability.

Expanded Refunds and New Deductions: Transforming Taxpayer Outcomes

2025 and 2026 mark the most significant tax benefit expansions in over a decade, with a focus on enhancing support for families, hourly workers, seniors, and residents of high-tax states:

• Child Tax Credit (CTC) and Additional Child Tax Credit (ACTC)
  Adjusted income thresholds and increased credit amounts are delivering markedly larger refunds to many middle-income families. These changes offset inflation’s impact on household budgets, but verifying eligibility remains vital to avoid IRS credit denials.

• Earned Income Tax Credit (EITC) and Premium Tax Credit (PTC)
  Now fully inflation-indexed, these credits maintain their value for low- and moderate-income workers, providing critical relief amid rising living costs. However, their refund timing continues to be affected by PATH Act withholding rules.

• Adoption Tax Credit
  With the credit now fully refundable and indexed for inflation, adoptive families see the credit amount rise to $17,280 for 2025, significantly easing adoption-related expenses.

• Qualified Overtime Compensation Deduction (QOCD)
  This landmark deduction permits eligible hourly employees to exclude certified overtime pay from taxable income, potentially boosting refunds substantially. Yet, widespread delays in employer certification are emerging as a key obstacle, leaving many eligible workers unable to claim the benefit this season.

• Inflation-Adjusted Tax Brackets and Standard Deductions
  Tax brackets and standard deductions continue to rise, with seniors and heads of household seeing notable increases—such as a nearly $1,000 bump for married filing jointly in 2026—helping reduce taxable income amid fixed or limited earnings.

• Temporary SALT Deduction Cap Increase
  The SALT deduction ceiling has been raised from $10,000 to $40,000 for 2025 and 2026, with income-based phase-outs. High-tax states like California, New Jersey, and Michigan stand to benefit, but taxpayers must carefully calculate deductions to maximize benefits within phase-out limits.

• New “No Tax on Tips” Deduction
  Introduced for 2026, this deduction excludes an average of $1,400 of tip income from federal taxation, offering important relief to millions in the service industry who often face challenges reporting tips accurately.

Operational and Eligibility Frictions: The Other Side of the Refund Equation

Despite enhanced credits and deductions, the operational environment continues to create bottlenecks and uncertainties that can delay or reduce refunds:

• PATH Act Refund Withholding and Increased CP79 Credit Denials
  Refunds involving EITC and ACTC remain subject to mandatory withholding until mid-February or later, delaying funds for many. Furthermore, the IRS has escalated issuance of CP79 notices, informing taxpayers of credit denials or reductions due to eligibility discrepancies or data mismatches. Prompt, accurate responses with supporting documentation are essential to avoid further delays or permanent refund reductions.

• ID.me Identity Verification Backlogs
  The IRS’s reliance on the ID.me platform to combat fraud has led to significant verification delays, with some taxpayers reporting multi-week wait times before completing identity checks. This backlog is a key factor in slow refund processing.

• Employer Certification Delays for QOCD
  Since claiming the QOCD requires employer certification of overtime hours, delays or refusals from employers have prevented many eligible workers from claiming the deduction. Tax professionals emphasize early communication with employers to secure timely certification.

• State Conformity Challenges and Paper Filing Delays
  Several states—including California, New York, Illinois, South Carolina, and Michigan—have yet to fully align their tax codes with 2025 federal changes, complicating state filings and refund timelines. Paper returns, still necessary for many complex filings or corrections, continue to face significant processing delays amid IRS backlogs and stalled digitization efforts.

• Treasury Offset Program (TOP) Refund Seizures
  Refund offsets to satisfy outstanding debts (e.g., child support, defaulted student loans, unpaid taxes) continue without taxpayer notification in many cases, reducing refund amounts unexpectedly. The IRS Taxpayer Advocate Service (TAS) remains a crucial resource for those impacted.

• Increased Manual Reviews and Fraud Audits
  To combat refund fraud, the IRS has heightened scrutiny of returns claiming multiple refundable credits. This has increased audit risks and extended processing times for affected taxpayers.

Special Populations: Seniors and Military Face Unique Filing Complexities

• New SSA, SSI, and SSDI Form Changes for Seniors
  Redesigned Social Security and disability income forms required for 2026 returns have introduced confusion, leading to misreporting and refund delays. Additionally, a retroactive Social Security tax adjustment necessitates some seniors to file amended returns. The IRS has launched instructional videos and enhanced online resources to assist seniors in navigating these complexities.

• Military Taxpayer Support
  Military personnel and their families benefit from expanded IRS guidance clarifying deployment-related credits, special income reporting rules, and dedicated helplines. These efforts aim to simplify filing and ensure military taxpayers fully leverage available benefits.

Refund-Dependent Households and the Importance of Accurate Filing Identifiers

Recent consumer-focused research highlights that a significant share of American taxpayers—especially those living paycheck-to-paycheck—rely heavily on tax refunds as a critical source of cash flow. Delays in refund issuance can therefore have immediate and severe financial consequences.

Moreover, a new IRS and tax software initiative emphasizes the necessity of providing correct filing identification numbers, such as Prior Year Adjusted Gross Income (AGI) or electronic filing PINs, to reduce e-filing rejections and identity verification friction. Taxpayers who cannot locate these numbers are advised to:

• Use the IRS Online Account portal to retrieve prior-year tax information.
• Contact the IRS or tax preparers for assistance when previous records are missing.
• Consult recent guidance explaining how to obtain or substitute missing information to avoid filing delays.

Practical Tax Filing Strategies to Maximize Refunds and Minimize Delays

Taxpayers can employ several best practices to navigate the evolving tax environment effectively:

• File Early and Electronically
  Early submission and e-filing reduce the risk of IRS backlog delays.

• Complete ID.me Verification Promptly
  Prioritize completing identity verification to avoid refund holds.

• Verify Prior-Year Filings and Documentation
  Ensure 2024 returns were properly filed and accepted, using IRS tools as needed.

• Respond Quickly and Accurately to IRS Notices (e.g., CP79)
  Timely provision of requested documentation helps prevent further refund delays.

• Engage Employers Early for QOCD Certification
  Hourly workers should initiate conversations with employers about QOCD certification requirements before filing.

• Maintain Comprehensive Records
  Keep tax returns, IRS correspondence, payment receipts, and employer certifications organized.

• Leverage IRS Online Tools and Free Assistance Programs
  Utilize the IRS Refund Status tool, educational publications, Taxpayer Advocate Service, and Volunteer Income Tax Assistance (VITA) program.

• Guard Against Scams
  Verify tax preparers’ credentials, avoid suspicious communications, and report suspected fraud promptly.

Conclusion: Preparing for 2026 and Beyond

The 2025–2026 tax seasons underscore a historic expansion in taxpayer benefits coupled with persistent operational challenges. While expanded credits, new deductions, and inflation indexing provide meaningful relief for millions, IRS procedural backlogs and state conformity issues introduce significant friction.

For taxpayers—especially those relying on refunds for essential expenses—proactive filing strategies, thorough documentation, early employer engagement, and prompt IRS communications are more important than ever. Leveraging IRS resources, free assistance programs, and staying vigilant against scams can help ensure taxpayers unlock the full value of the new tax reforms while minimizing delay and frustration.

With continued legislative and administrative efforts underway to improve IRS processing and state-federal alignment, taxpayers can look forward to a gradually more efficient system—but only if they remain informed and prepared in this transformative tax environment.
