Yes, IRAS updates its calculators to reflect prevailing rates and rules, and it publishes year-specific versions where relevant – for example a Year of Assessment (YA) 2026 Income Tax Calculator for tax-resident individuals, and the Basic Corporate Income Tax Calculator for the applicable YA. Using the IRAS version ensures you are applying the correct year's rates, reliefs and thresholds.
You can find the current calculators on the IRAS website under Quick Links → Calculators (iras.gov.sg/quick-links/calculators), or via the calculator links on our site, which point you to those IRAS tools. As the tools give estimates for guidance, anything you intend to rely on – for filing or a major decision – should be confirmed with IRAS or with us. Apexia can prepare a precise computation for your specific circumstances.
