Singapore’s Move Towards E-Invoicing and Digital Tax Reporting

Singapore is introducing mandatory e-invoicing and direct tax data reporting to improve tax compliance, requiring businesses to modernize their accounting systems. A phased rollout begins in May 2025, and companies must adapt to real-time tax reporting to stay compliant and avoid audit risks.

Singapore has built a strong digital government system, and businesses are now expected to follow suit with tax reporting. Currently, GST-registered businesses file quarterly returns manually via IRAS’ myTax Portal. However, planned changes will introduce mandatory electronic invoicing (e-invoicing) and direct tax data reporting to improve tax compliance.

E-invoicing automates invoice data exchange between vendors and customers, reducing manual processes. While Singapore introduced the InvoiceNow network in 2019, it did not include tax reporting. In 2024, IRAS and IMDA announced a phased rollout of an upgraded e-invoicing system, requiring businesses to report transaction-level data directly to IRAS. A pilot launch begins on May 1, 2025, with gradual expansion over the following years.

Businesses must adapt their accounting and billing systems to support real-time tax data transmission. They may face initial costs for system upgrades and integration, choosing between in-house solutions, ERP add-ons, or third-party providers.

Many businesses still rely on manual tax processes, risking errors and inefficiencies. With tax authorities gaining access to real-time transaction data, businesses need to modernize their tax functions to avoid compliance risks and stay ahead of audits. Investing in automation will help businesses align with Singapore’s digital tax transformation.
