Blog, Corporations, ONESOURCE November 20, 2024

Businesses that do not have sound tax provision processes are at an elevated risk of damaging their company’s financial health. Interim tax reporting plays a pivotal role in providing valuable financial information between annual reporting periods. Businesses can effectively navigate this process by understanding the significance of interim tax reporting and following best practices.

Summary 

  • Interim tax reporting provides crucial financial information between annual reports, helping stakeholders evaluate risks and make informed decisions.
  • UK companies must comply with IFRS standards IAS 34 and IAS 12 for interim reporting, ensuring consistency and comparability.
  • Three main calculation methods for interim reporting: annual effective tax rate, quarterly effective tax rate, and cumulative effective tax rate.
  • Challenges include inconsistent policy application, estimating annual effective tax rates, and adapting to tax law changes. Robust internal controls are essential.

Why is interim reporting important? 

Interim tax reports give stakeholders important financial information needed to evaluate tax-related risks and opportunities, and to make informed investment or lending decisions. Moreover, interim tax reporting enables businesses to identify and address tax-related issues proactively. This helps mitigate potential risks, optimise tax strategies, and enhance financial performance.
Furthermore, interim tax reporting contributes to the accuracy and reliability of financial statements. By ensuring that interim tax provisions are properly recorded and reported, companies can enhance the credibility and transparency of their financial information.

In the UK, interim tax reporting is crucial for companies that elect or have to prepare interim financial statements complying with International Financial Reporting Standards (IFRS) and is governed by IAS 34 Interim Financial Reporting and IAS 12 Income Taxes. Adherence to these standards enables users to make meaningful comparisons between companies and over different reporting periods.

Providing accurate, reliable financial information 

IAS 34 provides guidance on all aspects of interim financial reporting and companies must:

  • Use consistent accounting policies in both interim and annual financial statements.
    Recognise revenue and expenses in the interim period in which they are earned or incurred.
  • Disclose certain information in their interim financial statements, such as the nature and amount of any significant non-recurring items.
  • By adhering to these guidelines, companies can improve the transparency of their financial statements and make it easier for investors to understand their financial performance.

Main calculation methods for interim reporting: 

  • Annual effective tax rate method: This involves multiplying the company’s pretax income for the interim period by the annual effective tax rate, which is the company’s expected income tax expense for the year divided by expected pretax income for the year.
  • Quarterly effective tax rate method:  Similar to the annual rate method but uses the quarterly effective tax rate instead.
  • Cumulative effective tax rate method: More complex but potentially more accurate, this method involves multiplying cumulative pretax income for the year-to-date by the cumulative effective tax rate.

Overcoming challenges in reporting 

A common challenge is the inconsistent application of accounting policies, which can occur when different accountants or departments within a company interpret and apply accounting rules differently.

Another challenge is the difficulty in accurately estimating the annual effective tax rate. The rate, which can be tough to estimate is the company’s expected income tax expense for the year divided by its expected pretax income for the year.

Changes in tax laws or regulations can also present challenges. When changes occur, companies must update their interim tax provisions, which can be a complex and time-consuming process. Complex tax structures can also make interim tax reporting more burdensome as companies may find it difficult to allocate income and expenses to interim periods.

All of these challenges can potentially lead to material errors. To ensure accurate interim tax reporting and compliance with IFRS, companies should have a robust system of internal controls in place, including procedures for identifying and correcting errors and staying up to date with the latest tax regulations.

Five tips for accurate interim tax reporting: 

  1. Reconcile interim tax provision with actual tax liability: This step is essential to ensuring the accuracy of the interim tax provision and preventing over- or under-provisioning for income taxes. Start by comparing the interim tax provision to the actual tax liability from the prior year. This will provide a baseline for making necessary adjustments.
  2. Thoroughly document all assumptions and methodologies: Transparency is key in interim tax reporting. Documenting sources, calculations, and conclusions enhances clarity and facilitates easy auditing.
  3. Monitor tax law changes: Make prompt adjustments to the interim tax provision when new laws are passed, or existing laws are updated.
  4. Automate processes: Automation can minimise the risk of errors and omissions in the interim tax reporting process, and it can free up valuable time for finance professionals to focus on strategic tasks.
  5. Stay informed and seek professional guidance: Keep abreast of the latest developments in tax regulations and accounting standards. If needed, seek guidance from tax professionals or external auditors.

By implementing these practical tips and staying informed, companies in the UK can enhance the accuracy of their interim tax reporting and mitigate potential risks related to tax disclosures.
