Boost Compliance and Accuracy: How to Improve Your Company’s Tax Accounting

Effective tax accounting is a complex and high-stakes function. The accuracy of tax provisions is critical to financial reporting, yet vulnerabilities exist due to the reliance on spreadsheets and the dynamic nature of tax regulations. A deep understanding of both tax law and business operations is essential for navigating a constantly evolving landscape. The subjective nature of tax accounting, coupled with the complexity of tax software and data discrepancies, introduces significant risks. To mitigate these challenges, organizations must prioritize data integrity, invest in skilled tax professionals, and implement robust control mechanisms.

Key Mistakes for Corporate Tax Leaders to Avoid

Corporate tax management is fraught with challenges and complexities that can lead to significant consequences if not handled properly. From a lack of technical expertise in tax accounting to ineffective project management, corporate tax leaders must navigate a multitude of potential shortcomings.

Most companies use some combination of internal and external resources to manage various income and other tax reporting activities and responsibilities. These functions are usually coordinated by a tax leader within the organization or another responsible party, such as the controller or CFO.

Due to constant changes in tax law and its inherent complexity, we often see errors in tax reporting related to financial statement preparation. Here are the top mistakes corporate tax leaders should avoid in maintaining compliance, accuracy, and financial integrity. By understanding these common errors, businesses can implement strategies to mitigate risks and enhance their tax management practices.

1. Lack of Tax Accounting Expertise

Companies must accurately account for income and other taxes in their financial statements, a distinct requirement from preparing income tax returns. Tax provisions, estimates set aside to cover future tax liabilities, are a crucial component of financial reporting. Calculated using generally accepted accounting principles (GAAP)-based information, these provisions are based on taxable income, expenses, and applicable tax laws. Given the timing differences and specialized expertise needed for tax accounting, discrepancies between tax accounting and tax returns are common.

A business whose tax professionals lack tax accounting expertise may face several serious issues:

  • Lack of Auditor and Investor Confidence: If the company’s external auditors or tax regulating authority identify errors, it can trigger a restatement or recast of the financial statements. This scrutiny undermines stakeholder confidence in the company’s financial reports.
  • High Costs: Correcting mistakes made by an underqualified tax team can be incredibly expensive.

2. Spreadsheet Errors

Most accounting departments use a variety of Excel spreadsheets to calculate tax accounting entries. A critical mistake in corporate tax management is relying solely on these spreadsheets for calculations without a second review by tax experts or specialized software. These spreadsheets often include complex formulas with a tremendous amount of financial data without adequate controls over the integrity of data inputs and calculations. The possibility of one figure or calculation being wrong is high—even experienced professionals can miss these errors, making this area particularly prone to mistakes.

To mitigate risks, it’s crucial to have adequate spreadsheet controls, including a robust review process:

  • Review Process: Every spreadsheet should be reviewed by a second person who understands the spreadsheet and can identify potential errors.
  • External Review: Consider having in-house tax leaders or an outside firm prepare the provision and another firm review it to provide an extra layer of oversight and assurance.

3. Poor Project Management

Often, errors are the result of poor project management. Effective project management is crucial for accurate and timely tax accounting calculations. Unfortunately, companies often overlook this aspect, leading to rushed and incorrect work.

Effective project management involves:

  • Planning Early: Start early in the financial reporting process.
  • Task Identification: Identify all tasks, manage time effectively, and understand the amount of work required.
  • Consider Changes: Consider the impact of business changes, such as acquisitions/dispositions and geographic shifts.
  • Understand New Rules: Stay updated with changes in tax rules and regulations.

4. Disconnected from the Business

We see tax accountants who are unfortunately disconnected from the business. They are too often buried in detail, which may lead to making false assumptions in tax accounting calculations.

To avoid these pitfalls, tax accountants should:

  • Communicate Regularly: Maintain regular communication with the CFO or controller to understand what’s happening in the business.
  • Ask Questions: Ask open-ended questions about the business’s performance, significant changes during the year, and specific details like sales tax obligations.
  • Review Public Information: Review company press releases or SEC filings (if the company is public) and understand the states and other geographies where the company operates and employs people.

By realizing how common these mistakes are and correcting them before problems arise, companies can better prevent costly errors, maintain auditor and investor confidence, and ensure accurate and compliant financial reporting. Staying proactive and informed, and leveraging people and organizations with the right expertise, will help corporate tax leaders steer their organizations through the intricate landscape of tax regulations effectively.
