Quick answers to common questions about our services
How much does it cost to outsource accounting in Singapore?

Costs depend on your industry, transaction volume, and complexity. We provide transparent quotes tailored to your business needs after a free consultation. Speak to us to find out more.
Do I need GST registration?
▼
In Singapore, GST registration is compulsory if your company's taxable turnover exceeds S$1 million in the past 12 months, or is expected to exceed S$1 million in the next 12 months.

Can you help if I haven't filed taxes for previous years?

Absolutely. We can communicate with IRAS on your behalf to help settle outstanding filings and resolve company fiscal difficulties. We'll prepare the necessary returns for prior years and work to minimise any penalties. The sooner you reach out, the better — early action demonstrates good faith to the authorities.

GST Services
Simplifying Compliance. Enabling Business Growth.
Goods and Services Tax (GST) is a consumption-based tax (currently 9%) applied to the import of goods into Singapore and the supply of goods and services locally. GST is ultimately borne by the end consumer, while businesses act as collection agents on behalf of IRAS. Proper GST management ensures regulatory compliance, an optimised tax position, and improved financial visibility.

Do You Need to Register for GST?
Registration is compulsory if your annual taxable turnover exceeds S$1 million, or is expected to exceed S$1 million in the next 12 months. You may also register voluntarily to claim input tax and enhance business credibility.
How GST Works
You charge GST to your customers (Output Tax), you pay GST to your suppliers (Input Tax), and you pay IRAS the difference. GST payable = Output Tax – Input Tax.
GST Schemes We Help You Leverage
Major Exporter Scheme (MES)
Zero-GST Warehouse Scheme
Tourist Refund Scheme
Improve cash flow and reduce tax burden
Indicative pricing: GST returns from $500/return.
Withholding Tax Services
When a Singapore company makes certain payments to non-resident individuals or companies, it is required by law to withhold a percentage of the payment and remit it to IRAS. Failure to comply can result in penalties and interest charges. CMX Accounting & Tax Services helps you navigate withholding tax obligations with confidence.

Assessment of withholding tax obligations on payments to non-residents
Preparation and filing of withholding tax returns (Form IR37, IR21)
Timely remittance to IRAS within statutory deadlines

Common Payment Types Subject to Withholding Tax
Royalties — 10% withholding rate
Interest payments to non-residents — 15%
Technical service fees — prevailing corporate tax rate (17%)
Management fees to non-residents — prevailing corporate tax rate (17%)
Rental of movable property — 15%
Directors' fees to non-resident directors — 22%
Advisory & Optimisation
Review of Double Taxation Agreements (DTAs) for reduced rates
Advice on structuring cross-border payments
Application for Certificate of Residence (COR) where applicable
Resolution of withholding tax disputes with IRAS
When Must You Withhold?
You must file and pay withholding tax to IRAS by the 15th of the second month from the date of payment to the non-resident. Late payment attracts a 5% penalty and interest charges.
Double Taxation Agreements (DTAs)
Singapore has an extensive network of over 90 DTAs. If your non-resident payee is from a DTA country, reduced withholding tax rates may apply. We help you identify and apply the correct treaty benefits.
Indicative pricing: Custom quote based on volume and complexity of cross-border payments.
