Maximising Efficiency: A Holistic Approach to Statutory Reporting and Tax

13 February 2025 · 8 min read · By Mark Hart

Picture this: it is year-end. Your team is scrambling to produce statutory accounts and corporate tax returns. You are working from the same trial balance, but in two different systems, maintained by two different people - neither of whom has a clear view of what the other is doing.

A late adjustment arrives from the finance team. Both processes need to restart. Emails fly. Spreadsheets multiply. The audit deadline moves closer.

This is not an unusual scenario. For many finance and tax functions in multinational groups, it is just how year-end works. But it does not need to be.


The case for integration

According to Deloitte’s 2023 Global Tax Transformation Survey, 67% of tax leaders are actively exploring integrated processes to streamline compliance. The direction of travel is clear - the question is how to get there in practice.

Statutory reporting and tax compliance draw on the same underlying data. When they operate on disconnected systems, that data gets duplicated, reformatted, and manually re-entered at every handoff. Each of those steps is a source of error, a control weakness, and a time cost.

The benefits of connecting these processes are not theoretical:

  • A single change to a tax position flows through automatically, without parallel updates in two places
  • Disclosures in statutory accounts draw directly from the same calculations as the tax return
  • The audit trail is clear and consistent - one record, not two versions that need reconciling
  • Compliance deadlines become achievable rather than aspirational
  • Digital filing requirements - including Companies House mandatory software-only iXBRL filing for accounts filed on or after 1 April 2028 - become significantly easier to meet when your data and iXBRL tagging sit in a connected system

Template-driven statutory reporting

Platforms like ONESOURCE Statutory Reporting work from templates - preconfigured financial statement structures for UK GAAP, IFRS, FRS 101, and other frameworks. The benefits of a well-implemented template approach include:

  • Consistent formatting across all entities, every period
  • Automated population of standard note disclosures from structured data inputs
  • Instant period-on-period comparative generation
  • Built-in iXBRL tagging for digital filing
  • Roll-forward of opening balances, removing a significant manual step each period

For groups with large entity counts - 20, 50, 100 entities - the efficiency gains from template-driven reporting are proportional to the number of entities. Every entity that would otherwise require manual preparation now benefits from the same automated process.


Two integration points that matter most

If you are already using ONESOURCE Corporate Tax, connecting it to ONESOURCE Statutory Reporting removes the two biggest sources of manual effort in the joint process.

Tax provision into statutory disclosures The current and deferred tax notes in statutory accounts flow directly from the tax provision. In a connected environment, a change to the tax computation flows through automatically to the statutory accounts. No re-keying, no reconciliation, no risk of the accounts and the return telling different stories.

Corporate tax returns and the trial balance Both processes start from the same trial balance. A validated, shared TB means both processes draw from consistent numbers from the outset - reducing the risk of discrepancies during review and eliminating the need to maintain two independently extracted datasets.

Further automation

Beyond the platform integration itself, there is a further layer of automation that many groups have not yet explored.

  • Automated trial balance loading - rather than exporting and reformatting a TB manually, an Alteryx workflow pulls it from the ERP, validates it, and loads it directly. We have published a demonstration of this on YouTube showing the end-to-end process.
  • Automated disclosure population - structured data inputs can drive the population of standard note disclosures, reducing the time spent drafting and checking standard language
  • Validation and exception reporting - automated checks flag anomalies before they become audit findings, rather than after

For groups running 20 or more UK entities through a statutory reporting cycle, the combination of connected platforms and automated data flows can reduce total compliance hours significantly. The gains are real - they just require an upfront investment in getting the setup right.


Final thoughts

The question is not whether integration and automation are worth pursuing. The efficiency case is well established. The question is where to start.

For most organisations, the most impactful first step is connecting corporate tax and statutory reporting on a shared platform - even if full automation of data flows comes later. The reduction in manual effort from that single integration is usually enough to justify the project on its own.
