How to Keep IRAS-Compliant Accounting Records in Singapore (SME Guide)

For SMEs in Singapore, keeping accounting records compliant with IRAS requirements isn’t optional — it’s a core part of running a sustainable business. Yet for many founders, compliance feels complex, time-consuming, and easy to get wrong, especially as transaction volumes grow.

The good news is that IRAS compliance doesn’t have to be difficult. With the right structure, habits, and tools, SMEs can stay compliant while keeping their finance operations lean and efficient.

IRAS requires businesses to maintain proper accounting records for at least five years, including invoices, receipts, bank statements, payroll records, and supporting documents for GST (if applicable). These records must be complete, accurate, and retrievable when requested.

The challenge isn’t understanding the rule — it’s executing it consistently in day-to-day operations.

Many compliance issues arise not from intent, but from fragmented workflows: documents scattered across emails, paper receipts left unrecorded, transactions entered late, or manual spreadsheets that don’t reconcile properly.

A strong compliance foundation starts with timely and accurate record-keeping. Every transaction should be captured as close to real time as possible, with clear documentation attached. This reduces the risk of missing records and ensures that figures remain consistent across ledgers, bank balances, and reports.

AI-powered accounting platforms like ccMonet help SMEs automate this process. Receipts and invoices can be uploaded via mobile, automatically read and categorized by AI, and stored securely with proper audit trails. This ensures that records are complete, searchable, and ready when needed.

Another key compliance requirement is proper classification. Income, expenses, and GST-related transactions must be recorded under the correct categories. Misclassification is one of the most common reasons for IRAS follow-ups, especially during GST reviews.

AI reduces this risk by applying consistent classification rules across transactions and flagging anomalies early. ccMonet combines AI automation with expert review, adding an extra layer of assurance that records are accurate and aligned with regulatory expectations.

Bank reconciliation is also essential for IRAS-compliant records. Your accounting data must align with actual bank movements — unexplained differences raise red flags. Delayed or manual reconciliation often leads to errors that are difficult to trace later.

With AI-driven bank reconciliation, mismatches are identified quickly, duplicates are flagged, and missing entries are highlighted before they become compliance issues. This keeps your books clean throughout the year, not just during audits or filings.

For GST-registered SMEs, compliance depends heavily on consistency and traceability. Supporting documents must clearly justify GST treatment, and figures reported must be backed by transaction-level data. Preparing GST returns becomes significantly easier when records are already structured, reconciled, and reviewed.

Instead of scrambling at quarter-end, AI accounting enables ongoing readiness — turning GST preparation into a verification step rather than a cleanup exercise.

Ultimately, IRAS compliance isn’t about doing more work — it’s about doing the right work, earlier and more accurately. Automation, real-time visibility, and proper controls allow SMEs to stay compliant without overwhelming their teams.
