Agentic AI and technology innovation: The new normal

Artificial intelligence now defines essential audit work. Understanding how AI impacts workflows determines success in 2026.

How does agentic AI change audit workflows?

The audit profession has reached a tipping point. Firms not investing in AI risk being left behind.

Agentic AI systems work autonomously, making decisions and taking actions to complete specific goals. Major vendors including Intuit, Wolters Kluwer, and Thomson Reuters have launched cloud-based platforms embedding AI capabilities into audit and firm management software.

The most practical trend for 2026 is the move from single-step automation to systems managing entire workflows. Instead of completing one task and stopping, agentic systems maintain context, monitor progress, and decide what to do next.

Major applications reshaping audit:

    • End-to-end AI integration: Expected by late 2026, covering planning, risk assessment, evidence collection, and financial statement review
    • Controls testing automation: Identified by the AICPA as the greatest benefit area
    • Autonomous agents: Experienced auditors focus on complex procedures while agents execute multistep processes
    • Cloud-based transformation: Systems streamline communication, allowing teams to focus on higher-value tasks

By tapping into the work of auditors who faced similar scenarios, assisted decision-making enhances risk identification with insight from the wider audit community.

AI becomes mandatory for competitiveness

AI and automation now represent standard operating procedure for competitive audit firms. Technology is a “must have” for quality, productivity, and the bottom line.

An emerging challenge: As clients deploy their own AI systems, you’re increasingly asked to provide AI assurance, verifying the accuracy, reliability, and compliance of AI-driven processes.

Cybersecurity emerges as critical focus

Cybersecurity, particularly for AI tools, has emerged as a critical focus area. Cyberfraud poses both the most likely and most significant fraud risk by a substantial margin.

Three critical focus areas:

    1. Data security verification: Validating client data protection throughout collection, storage, and processing cycles
    2. Cyber disruption priority: Industry experts identify this as a top risk priority alongside economic pressure and geopolitical uncertainty
    3. AI-driven threat sophistication: Traditional control frameworks often prove insufficient against threats unfolding at machine speed

Audit firms must respond with enhanced procedures, continuous monitoring capabilities, and specialized cybersecurity expertise.

The audit talent landscape: Skills, shortages, and strategic roles

The accounting workforce crisis deepens as experienced professionals exit and fewer newcomers enter. Firms must rethink talent strategies and skill requirements.

What is the state of audit talent?

Nearly three-quarters of CPAs are at or near retirement age. The number of people sitting for the CPA exam has declined by more than 30% since 2016. Finance roles requiring CPA credentials now take 73 days to fill — 41% longer than comparable positions.

Forecasted enrollment declines could reduce accounting students by up to 15% between 2025 and 2029. The traditional talent pipeline is broken.

Modern auditors need expanded competencies

Clients are asking you to perform dramatically expanding scopes of work. Modern auditors must provide assurance on reports, navigate infinite data sets, and work with new technology, all while maintaining professional skepticism.

Critical skill shifts:

    • Traditional expertise plus emerging competencies: Data analytics, AI fluency, and cybersecurity knowledge are now core competencies; auditors must interpret AI logic, validate algorithmic outputs, and assess AI-related risks
    • Soft skills elevation: Communication and strategic thinking distinguish high performers; translating data anomalies into risk narratives is essential
    • Continuous learning imperative: The best auditors bridge data, judgment, and strategy in rapidly evolving environments

Audit is advancing from compliance-focused function to a strategic driver of trust and risk intelligence.

Technology attracts next-generation talent

Technology serves dual purposes: improving efficiency while making audit careers more attractive to tech-savvy professionals. Cloud-based audit technology and AI give teams flexibility and help them find information to confidently complete their work.

Flexible work arrangements, modern technology platforms, and career development in emerging areas like AI, ESG, and cybersecurity all contribute to stronger talent attraction and retention.

Continuous assurance and real-time auditing

The traditional year-end audit rush is giving way to perpetual monitoring and ongoing risk assessment.

How is continuous assurance impacting the audit industry?

One of the most significant shifts in 2026 is movement toward continuous assurance fueled by automation and real-time data ingestion. Client transactions now flow continuously into AI-driven engines, creating 80-90% complete deliverables by year-end with minimal human intervention.

Continuous audit aided by agentic AI monitors client systems year-round, flagging issues as they occur. This provides earlier risk identification, improved accuracy through ongoing validation, and enhanced client value as you provide strategic insights throughout the year.

Workflows fundamentally transform

The move from periodic to perpetual monitoring requires fundamental rethinking of methodologies. Integrating audit processes into client systems allows seamless data flows and automated testing.

Your role evolves from data gatherer to strategic advisor and risk interpreter. Rather than spending months collecting historical information, you focus on understanding emerging risks, interpreting AI-identified patterns, and providing forward-looking guidance.

This transformation doesn’t eliminate professional judgment. It elevates it.

Fraud detection and prevention: Rising risks and AI solutions

Fraud risks are escalating in frequency and sophistication. You must leverage AI-powered tools to detect schemes faster and prevent losses.

What is the current state of fraud?

Two-thirds of participants in a recent consumer fraud survey indicated fraud has increased over the past two years, with more than 70% rating the current level as medium or high. Looking forward, two-thirds believe fraud will increase over the next two years.

U.S. public companies lost an average of 1.06% of revenue to known fraud in 2024. The same industry research estimates the typical organization loses 5% of revenues annually to fraud.

Both PCAOB and SEC actions related to financial reporting fraud increased in 2023, with the SEC bringing 70 accounting and auditing enforcement actions. Approximately 27-33% of settled disciplinary orders focus on improper revenue accounting.

How does AI-powered detection help auditors?

AI-powered fraud detection capabilities transform how you identify suspicious activities. Pattern recognition and anomaly detection flag unusual transactions that human auditors might miss.

Continuous monitoring enables real-time fraud detection rather than periodic assessments. The median fraud scheme took 12 months to uncover, with average losses of $9,900 per month, highlighting the value of faster detection.

AI-driven risk scoring helps you prioritize efforts, focusing investigative resources on highest-risk areas. Assisted decision-making technology can proactively present risks you might not have considered, enabling faster, more confident audits.

Evolving standards and complex regulatory landscape

Regulatory complexity intensifies from PCAOB oversight to ESG mandates and trade policy impacts. You must navigate expanding requirements while developing expertise in emerging areas.

Regulatory complexity accelerates

Increased oversight from the PCAOB and SEC creates heightened scrutiny of audit quality. The SEC is considering changes to independence rules as technology and AI companies form complex partnerships. Regulators now expect stricter documentation and testing of controls.

Regulatory attention to digital assets and emerging technologies requires expertise in areas that didn’t exist a decade ago.

Where is ESG reporting mandatory?

The ISSB issued its inaugural IFRS Sustainability Disclosure Standards in June 2023. As of September 30, 2025, 17 jurisdictions have adopted the standards with 19 more planning future adoption.

ISSB rules create a common baseline for climate and sustainability reporting worldwide, helping you develop consistent methodologies and enabling companies to provide comparable disclosures.

You need specialized ESG knowledge to provide credible assurance on sustainability disclosures. This creates new service offerings and revenue opportunities. Firms that develop robust ESG assurance capabilities position themselves for competitive advantage.

Trade policies create audit complexities

Shifting trade policies and tariffs create accounting and reporting challenges you must evaluate across inventory costs and valuation, contract economics, impairment assessments, tax positions, and financial statement disclosures.

Even smaller firms will encounter clients affected by tariff volatility, making this a pervasive concern.

M&A activity: Growth strategy and complexity management

With an increase in M&A activity expected in 2026, auditors may face challenges in managing the complexities of the transaction and ensuring that financial reporting is accurate and reliable.

How does M&A drive firm growth?

Audit firms play a dual role: auditing clients going through a merger or acquisition while also acquiring firms of their own to further growth.

Strategic M&A priorities:

    • Talent acquisition: Acquiring firms or auditors with specialized expertise provides immediate capability enhancement
    • Service expansion: M&A enables rapid entry into high-growth service lines like ESG assurance and cybersecurity consulting
    • Technology capabilities: Acquiring firms with advanced AI and data analytics accelerates digital evolution
    • Geographic expansion: M&A provides market entry where organic growth would take years

Due diligence reaches new sophistication

You’re now providing technology and systems integration support. Acquirers are making ESG considerations standard in M&A due diligence. Geopolitical uncertainties impact transaction structures, requiring you to factor in regulatory risks across jurisdictions.

AI-powered analysis can tap into the work of auditors who faced similar risks and suggest risk areas you may not have considered.

Integration creates audit quality challenges

For audit firms pursuing M&A strategies, integration creates quality challenges. Integration of different firm cultures and methodologies can create inconsistencies. Quality control across expanded operations requires robust systems ensuring all engagement teams apply consistent methodologies.

Strategies for audit success in 2026

Success requires proactive innovation rather than reactive adaptation. Firms that strategically invest in technology, talent, and client-centric approaches while maintaining quality standards will thrive.

How can leading audit firms stay ahead?

Rather than reactively responding to audit industry challenges, leading firms anticipate trends and invest strategically.

Key success factors:

    • Strategic technology investment: The right cloud-based software catalyzes efficiency, empowering your team to focus on what truly matters
    • Continuous learning culture: Firms that invest in upskilling while recruiting diverse talent with multidisciplinary skills build resilient teams
    • Regulatory monitoring: Systems to monitor changes and assess their impact on audit methodologies
    • Balancing efficiency with quality: Using technology for routine tasks while ensuring human expertise drives critical decisions

Assisted decision-making technology can proactively present risks related to your engagement, enabling faster and more confident audits.

The audit profession stands at an inflection point. The convergence of agentic AI, reshaped talent needs, continuous assurance, heightened fraud risks, and expanding regulatory complexity creates both challenges and opportunities.

Here’s the strategic tension: While AI handles routine procedures faster than ever, the profession simultaneously needs more human judgment, not less. Auditors who thrive will master this paradox — leveraging automation while enhancing their core expertise.

Yet one constant remains: risk identification is central to your mission. The core value you provide — independent verification, risk assessment, and trusted assurance — endures even as methods continue to change.
