Frequently Asked Questions
When are corporate tax filing deadlines?
Companies generally file Estimated Chargeable Income within three months after their financial year end and file the annual corporate income tax return by the applicable IRAS deadline.
What is ECI and when do I need to file it?
Estimated Chargeable Income is a company's estimate of taxable profits. It is generally filed with IRAS within three months after the financial year end, unless an exemption applies.
What forms do I need to file for corporate tax?
The appropriate filing depends on the company and its income. Common filings include ECI and Form C-S, Form C-S Lite, or Form C with supporting schedules.
What happens if I file my tax return late?
Late filing may lead to reminders, estimated assessments, penalties, or enforcement action. Our team can help review outstanding filings and prepare a compliance plan.
Can I claim tax deductions for business expenses?
Business expenses are generally deductible when they are incurred in the production of income and satisfy Singapore tax rules. Supporting records should be retained.
