The Rise of AI in Accounting and Taxation: Opportunities, Risks, and the Road Ahead

By: Priyanka Sharma 

Introduction

Artificial Intelligence (AI) is no longer just a futuristic idea; it is already here and transforming how accountants and tax professionals work. From automating repetitive bookkeeping tasks to helping firms with forecasting tax liabilities and advising clients more strategically, AI is making processes faster, smarter, and more reliable.

Traditionally, accountants would spend countless hours on manual work such as entering data, reconciling spreadsheets, or navigating through thousands of pages of tax codes and regulations. Today, AI can handle much of that heavy lifting. This shift frees professionals to focus on what truly matters: understanding the client’s needs, providing them with valuable insights, and helping guide better business decisions.

 

1. What AI Means in Accounting and Tax

In the accounting and tax world, the most common  of ‘AI’ include:

• Machine Learning (ML): ’Machine Learning’ describes an AI that learns from past financial data. For example, it can automatically categorize expenses or detect unusual payments that might be errors or fraud.

• Generative AI (GenAI): ‘GenAI’ are tools that create content such as tax memos, audit summaries, or client-ready reports. This is done to help draft content before it is reviewed by a professional, like having a junior associate prepare quick drafts.

• Smart Automation: ‘Smart Automation’ is the process of combining AI with workflow automation to handle entire processes, such as  scanning invoices, entering data, reconciling accounts, and preparing draft tax returns.

• Decision Support: ‘Decision Support’ is AI-powered analytics that highlight unusual financial trends, suggest corrective actions, and surface risks, while leaving the final decisions in human hands.

 

2. How AI Adds Value in Accounting and Tax

AI is already making a measurable difference in the following areas:

• Bookkeeping and Closing Books: AI automates transaction classification, flags unusual entries, and extracts key details from invoices and receipts. This reduces errors and speeds up month-end close.

• Management Reporting and Forecasting: AI transforms raw trial balances into clear summaries with charts, variance explanations, and scenario modeling. For example, firms can model how a change in tax law or a dip in revenue will affect cash flow.

• Audits and Assurance: AI can scan thousands of journal entries or payroll transactions in seconds to spot anomalies. It can also prepare draft workpapers and cross-reference supporting documents, improving efficiency and consistency.

• Tax Compliance and Advisory: AI assists with preparing returns, reconciling book-to-tax differences, aggregating tax data across jurisdictions, monitoring regulatory updates, supporting transfer pricing, and forecasting future tax liabilities.

• Improving Client Service: AI-powered client portals can check for missing documents, send automated reminders, and even generate proposals and fee estimates based on past engagements.

 

3. Risks and Limitations to Watch Out For

Despite its benefits, AI is not perfect and must be used carefully. Some key risks include:

• Accuracy Issues: AI may produce incorrect or incomplete outputs. Human review is always required before sharing results with clients or regulators.

• Data Privacy and Protection: Sensitive client data must only be processed in secure enterprise tools. Therefore professionals should never use  public consumer-grade AI apps.

• Regulatory Compliance: AI solutions must align with professional standards such as IRS Circular 230, AICPA guidelines, PCAOB rules, and global data privacy laws like GDPR.

• Bias in Models: AI trained on incomplete or one-sided data can give skewed results. Validation and transparency are critical.

• Cybersecurity Threats: AI platforms can become new entry points for cyberattacks. Strong security measures such as encryption, multi-factor authentication, and intrusion monitoring are essential.

 

4. Using AI Responsibly

To maximize the benefits of AI while minimizing risks, firms should establish strong controls and policies:

• Leadership Oversight: Senior management must set ethical standards, ensure accountability, and guide AI adoption.

• Approval Processes: Every AI use case should be documented, reviewed, and approved before implementation.

• Data Safeguards: Sensitive information should be anonymized where possible, with strict access controls in place.

• Human Oversight: All AI outputs that affect external reporting or client deliverables must be reviewed and approved by a qualified professional.

• Training and Upskilling: Teams should receive ongoing training on how AI works,

 

5. The Road Ahead

AI is rapidly becoming an essential tool in accounting and taxation. Firms that embrace AI tools responsibly will benefit from faster processes, greater accuracy, and stronger client relationships. Those that hesitate may struggle to keep pace with competitors who are already leveraging AI.

Used wisely, AI is not here to replace professionals, but to empower them to deliver greater value.
