Personal Income Tax Filing Made Simple

Personal income tax doesn't have to be complicated. At CWM, we assist individuals with the preparation and filing of their personal income tax returns, helping to ensure accurate submissions and timely compliance with IRAS requirements.

Whether you're a Singapore resident, Employment Pass holder, company director, or self-employed individual with multiple income sources, we help simplify the filing process and provide guidance based on your individual circumstances.

Personal Income Tax Filing Deadlines In Singapore

All Singapore taxpayers must file their personal income tax return annually with IRAS. Key dates to know:

15 April

Deadline for filing personal income tax returns by post.

18 April

Deadline for e-filing via MyTax Portal.

1 March

Employers are required to submit Form IR8A for employees by this date.

Missing filing deadlines may result in penalties, estimated assessments, or other enforcement actions by IRAS. If you require assistance with your filing, our team is here to help.

Personal Tax As A Foreigner Or Expat In Singapore

If you are working in Singapore under an Employment Pass, S Pass, or Dependant Pass, your tax obligations may differ from those of Singapore tax residents. Matters such as tax residency status, overseas income, and double taxation relief can affect your filing requirements.

We regularly assist foreigners and expats with:

  • Tax residency assessment: Determining whether you qualify as a Singapore tax resident and understanding the tax implications that apply.
  • Overseas income: Usually not taxable in Singapore, but exceptions exist for income received through Singapore employers or Singapore-sourced income included in employment remuneration.
  • Double taxation relief: Assistance in identifying and applying available tax relief under Singapore's tax treaty network.
  • Director's fees & equity income: Support in correctly reporting director's fees and other forms of taxable income.

If you're unsure which tax rules apply to your situation, our team can help provide clarity and guidance throughout the process.

Seamless GST Registration In Singapore

Getting your GST registration right is essential to meeting IRAS requirements and avoiding unnecessary complications. At CWM, we guide businesses through the GST registration process, helping determine whether compulsory or voluntary registration applies and assisting with the preparation and submission of the application.

Our team helps ensure that your registration is completed accurately and efficiently, reducing the risk of delays while helping your business remain compliant with IRAS regulations.

When Does GST Registration Become Compulsory?

Businesses are required to register for GST when their taxable turnover exceeds S$1 million, or when they are expected to exceed this threshold within the next 12 months.

What If I Didn't Register?

Failing to register on time may result in penalties or backdated GST liabilities imposed by IRAS.

To support a GST registration application, you may need the following documents:

  • GSA Business Profile: To confirm the company's registration details
  • Financial Records: Latest Financial Statements or Sales & Purchase Listings to support the company's turnover claims
  • Supplier Invoices: 3 recent supplier invoices and supporting documents demonstrating active business operations
  • Customer Invoices: 3 recent customer invoices and supporting documents verifying taxable sales activity

Voluntary GST Registration

Businesses that have not reached the compulsory registration threshold may still choose to register for GST voluntarily.

Voluntary registration may allow businesses to claim input tax on qualifying purchases and may be beneficial depending on the nature of the business and its customers.

Eligibility requirements and supporting documents may vary depending on your business circumstances. Contact our team to discuss your situation and determine whether voluntary GST registration is suitable for your business.

Frequently Asked Questions

A corporate tax service prepares and files your company's annual income tax return with IRAS, computes your chargeable income, identifies applicable tax exemptions, and handles any IRAS correspondence on your behalf. CWM coordinates the entire process and tracks all filing deadlines so nothing falls through the cracks.
Companies must file their Estimated Chargeable Income (ECI) within 3 months from the end of their financial year. The Corporate Income Tax Return (Form C-S, C-S Lite, or Form C) must be e-filed with IRAS by 30 November each year. Missing either deadline may result in penalties and estimated assessments from IRAS.
Most newly incorporated Singapore companies qualify for the Start-up Tax Exemption for their first three consecutive Years of Assessment, provided they are not investment holding companies or involved in property development for sale. Qualifying companies receive a 75% exemption on the first S$100,000 of chargeable income and 50% on the next S$100,000. CWM will confirm your eligibility and apply the exemption correctly when filing.
Singapore's corporate income tax rate is a flat 17% on chargeable income. Various exemption schemes and tax incentives can significantly reduce the effective rate for eligible companies, particularly in their early years of operation.
CWM regularly works with businesses that are behind on filings or have inherited messy records. Our team will review your current position, bring your accounts up to date, and get your tax filings back on track — including liaising with IRAS where necessary.
Form C is for companies with more complex tax affairs. Form C-S is a simplified return for companies with annual revenue of S$5 million or below that meet specific conditions. Form C-S Lite is an even simpler version for qualifying companies with straightforward tax positions. CWM will determine the correct form for your company and handle the filing accordingly.
