Accounting records should be maintained from the first transaction. The annual work then uses those records to prepare financial statements, ECI and the applicable corporate income tax return.
The service scope depends on transaction volume, record quality, GST status, payroll, foreign transactions and whether prior periods need cleanup.
If you are unsure where to start, these guides explain the common decisions before you appoint a provider or make a filing. This page explains how ProSec can assist with the actual filing and follow-up services.
Keep source documents and reconciliations current.
Scope depends on record quality and transactions.
GST and payroll are assessed separately where relevant.
No GST is added to the listed ProSec service fees. Full fees and inclusions
Tax filing relies on complete accounting records. Missing invoices, bank explanations or shareholder transactions should be resolved before filing.
| Service | Fee | Scope and boundaries |
|---|---|---|
| Dormant-company annual package | S$500/year | For qualifying dormant companies with simple records. Includes Annual Return filing and the ACRA fee; company secretary appointment is separate. |
| Annual accounting and tax package | From S$1,988/year | Bookkeeping, annual accounts and applicable corporate tax work within the agreed scope. Fee depends on transactions, records and complexity; GST is separately engaged. |
| GST registration | S$200 one-time | Application preparation and submission support. IRAS approval and applicable InvoiceNow requirements remain separate regulatory considerations. |
| Quarterly GST return | S$300 per quarterly return | Clients must provide all complete and accurate financial records and supporting documents required to prepare and file the quarterly GST return. Actual GST payable is not included in this service fee. |
The S$500 dormant-company package does not include company secretary appointment. Where services overlap, confirm a combined scope first; work already included in a package is not charged twice.
| Item | General timing | Preparation point |
|---|---|---|
| ECI | Generally within three months after FYE, subject to exemption rules | Draft accounts and tax adjustments |
| Corporate income tax return | According to the annual IRAS filing deadline | Final accounts, tax computation and supporting schedules |
| GST return | Based on the assigned GST accounting period | Tax invoices, claims, exports and reconciliations |
The exact filing obligation should be checked against the company’s FYE, IRAS notices and current filing status.
Businesses applying for voluntary GST registration from 1 April 2026 must meet the applicable GST InvoiceNow requirements using an InvoiceNow-Ready solution, regardless of incorporation date or business structure. Emailing a PDF is not InvoiceNow transmission. Other registrants enter in phases through 2031; check the business’s IRAS notification and implementation date. InvoiceNow does not replace GST returns or record keeping.

The applicable return depends on the company’s eligibility and tax matters. The accounts and tax computation should be prepared before choosing the form.
