While the Accounting and Corporate Regulatory Authority (ACRA) is where your business is legally born, the <\/span><b>Inland Revenue Authority of Singapore (IRAS)<\/b><span style=\"font-weight: 400;\"> is the agency you will work with throughout your company&#8217;s entire life.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">IRAS is far more than just Singapore&#8217;s &#8220;tax collector.&#8221; It is the central authority that administers the nation&#8217;s tax policies, manages the Goods and Services Tax (GST), and even disburses critical business grants. Understanding its role, requirements, and digital platforms is essential for legal compliance, financial planning, and operational efficiency.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This guide will provide a clear overview of IRAS&#8217;s primary functions and explain what every Singaporean business owner needs to know to manage their tax responsibilities effectively.<\/span><\/p>\n<div style=\"border-left: 4px solid #007BFF; background: #f0f8ff; padding: 25px; margin: 30px 0; border-radius: 8px; font-family: Arial, sans-serif; text-align: left;\">\n<h3 style=\"margin-top: 0; color: #007bff; font-size: 22px;\">Key Takeaways<\/h3>\n<ul style=\"margin: 15px 0; padding-left: 20px; color: #333; line-height: 1.6;\">\n<li><strong>What It Is:<\/strong> IRAS is the Inland Revenue Authority of Singapore, the main government agency responsible for administering and collecting all national taxes.<\/li>\n<li><strong>Core Functions:<\/strong> For businesses, IRAS manages Corporate Income Tax, Goods and Services Tax (GST), and Withholding Tax.<\/li>\n<li><strong>Your Identifier:<\/strong> IRAS uses your Unique Entity Number (UEN), issued by ACRA, as your primary Tax Identification Number for all business tax matters.<\/li>\n<li><strong>Digital-First:<\/strong> All tax filing and payments are done electronically through the IRAS myTax Portal, making familiarity with this portal essential.<\/li>\n<li><strong>Compliance is Key:<\/strong> Businesses must file tax returns accurately and on time \u2014 even if there is no tax payable or the business is making a loss.<\/li>\n<li><strong>Beyond Tax:<\/strong> IRAS also administers government payouts and schemes, such as the Wage Credit Scheme, offering additional support to businesses.<\/li>\n<\/ul>\n<\/div>\n<h2><b>IRAS&#8217;s Core Functions for Businesses<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">While IRAS manages many types of taxes, here are the most important ones that every business owner must understand.<\/span><\/p>\n<h3><b>1. Corporate Income Tax<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">This is the tax paid on the profits your company earns.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Filing Requirement:<\/b><span style=\"font-weight: 400;\"> All companies in Singapore are required to file an annual tax return (Form C-S or Form C) with IRAS, declaring their revenue and calculating their chargeable income.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Tax Rate:<\/b><span style=\"font-weight: 400;\"> Singapore is known for its competitive, flat corporate tax rate of <\/span><b>17%<\/b><span style=\"font-weight: 400;\"> on chargeable income.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Startup Tax Exemption:<\/b><span style=\"font-weight: 400;\"> New startups enjoy significant tax exemptions for their first three years, which greatly reduces their tax burden.<\/span><\/li>\n<\/ul>\n<h3><b>2. Goods and Services Tax (GST)<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">This is the 9% consumption tax levied on goods and services in Singapore.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Registration:<\/b><span style=\"font-weight: 400;\"> Your business is required to <\/span><b>compulsorily register for GST<\/b><span style=\"font-weight: 400;\"> if your annual taxable turnover exceeds <\/span><b>S$1 million<\/b><span style=\"font-weight: 400;\">. Businesses below this threshold can also register voluntarily.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Filing:<\/b><span style=\"font-weight: 400;\"> Once registered, you must file a <\/span><b>GST F 5 return<\/b><span style=\"font-weight: 400;\">, usually on a quarterly basis. This form reports the &#8220;Output Tax&#8221; (GST you collected from customers) and &#8220;Input Tax&#8221; (GST you paid to suppliers).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Payment\/Refund:<\/b><span style=\"font-weight: 400;\"> You must pay the net GST (Output Tax minus Input Tax) to IRAS by the deadline, or claim a refund if your input tax is higher.<\/span><\/li>\n<\/ul>\n<h3><b>3. Withholding Tax<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">This applies to businesses that make specific types of payments to non-resident companies or individuals (e.g., for services, interest, or royalties). Your business is responsible for &#8220;withholding&#8221; a portion of that payment and remitting it to IRAS.<\/span><\/p>\n<h2><b>The IRAS <\/b><b><i>myTax Portal<\/i><\/b><b>: Your Digital Gateway<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">All your interactions with IRAS will happen online.
