Annual Filing and Tax Compliance In Singapore
A Complete Guide for Foreign Entrepreneurs
Stay compliant with IRAS & ACRA — avoid penalties and late fees
If your company is incorporated in Singapore, keeping it in good standing involves more than just registration. You must comply with annual filing and tax reporting requirements under the oversight of ACRA (Accounting and Corporate Regulatory Authority) and IRAS (Inland Revenue Authority of Singapore).
Whether your company is active or dormant, local or foreign-owned, our team at Intraconnect Pte Ltd can manage your annual filing in Singapore and help you stay compliant — stress-free.
Types of filing:
There are 2 to 3 main types of filing applicable to every Singapore company, depending whether the company is registered for Goods and Services Tax (GST):
- ACRA Annual Return (Once Per Year)
- IRAS Corporate Tax Filing (Once or Twice Per Year)
- GST Return (Every Quarter)
What Are the Annual Filing Requirements in Singapore?
There are two key sets of obligations for every Singapore company:
1. ACRA Annual Return
Filed with ACRA via BizFile+, this includes:
Company details confirmation (directors, shareholders, secretary)
Financial year-end
AGM status
Financial statements (in XBRL if required)
Deadline: Within 7 months after FYE (Financial Year End)
Dormant companies must still file unless exempted.
2. IRAS Corporate Tax Filing
You must file:
Estimated Chargeable Income (ECI) – within 3 months of FYE
Form C-S or Form C – annual corporate tax return
Preparing Financial statements and tax computations are pre-requisites for filing your Tax Returns. These are usually prepared by a bookeeper or accountant. If you don’t have one, you should engage one – a professional who is familiar with IFRS and SFRS.
Deadline:
ECI (Estimated Chargable Income): within 3 months from Financial Year End (FYE).
Form C-S/C: by 30 Nov (for YA ending previous year)
ECI is a preliminary tax return. Not every small company might be required to file ECI. If the taxable income is zero, and the revenue is below 5 million Singapore Dollars, filing this return is not necessary. Please check with the lates requirements on the tax authority website: https://www.iras.gov.sg/taxes/corporate-income-tax/estimated-chargeable-income-(eci)-filing#eci-filing-waiver
What Happens If You Don’t File?
Late or non-compliance can result in:
💸 Penalties and late filing fines
📩 ACRA summons or court orders
🚫 Company being struck off
❌ Problems opening bank accounts or applying for visas
⚠️ IRAS audit flags and tax estimation (higher tax assumed)
We actively track and manage deadlines, and we’ll notify you well in advance.
For foreign entrepreneurs and small business owners, registering a company in Singapore offers:
100% foreign ownership
Simple incorporation process
Access to Southeast Asia markets
Strong intellectual property protections
Reputable international banking system
Favorable tax regime (including tax exemptions for new startups)
Whether you’re launching a startup, relocating your online business, or establishing a regional HQ, Singapore is a reliable and strategic choice.
GST Filing (If Applicable)
Not all companies in Singapore are required to register for GST (Goods and Services Tax). You must register only if your annual taxable turnover exceeds SGD 1 million, or if you expect to cross that threshold in the next 12 months. Once registered, you must file GST returns quarterly, even if there is no activity. Returns are submitted via IRAS and must be filed within 1 month after the end of each accounting period. We assist with both voluntary and compulsory GST registration, as well as ongoing GST filings and compliance.

USEFUL TIP:
What is XBRL?
Some companies in Singapore are required to file their financial statements in XBRL (eXtensible Business Reporting Language) format when submitting their annual return to ACRA.
Such companies are those with corporate shareholders or required to be audited as they are not falling into expempted category.
The XBRL format ensures standardised reporting for regulatory and analytical purposes.
Our team prepares and converts your financials into the correct XBRL format, ensuring fast, compliant filing via BizFile+.

FAQs – Annual filing in Singapore
Do I need to file ECI if my company is dormant?
If your company has no income, ECI is not required — but IRAS must be informed, and Form C-S (Lite) may still be needed.
What’s the penalty for late filing?
ACRA late filing starts from S$300-600 and can escalates to court action. IRAS may issue a Notice of Assessment with estimated tax if you miss deadlines and impose 5% on late tax payments.
Can I file everything myself?
Technically Yes, but it requires BizFile+ and MyTaxPortal access, financial statements, and tax knowledge. As for XBRL it is almost impossible to file without a proper training and tools. Most businesses outsource to avoid mistakes.
Do I need to prepare financial statements even if my company is inactive?
Yes — even dormant companies must prepare unaudited financials which are often called Zero figures.
