Managing personal finances in Singapore requires precision, especially when it comes to the annual tax filing. To help residents better plan their finances, I've built a comprehensive, interactive Singapore Income Tax Calculator.
This tool is designed to mirror the actual IRAS tax return structure, allowing for sophisticated estimations for the upcoming Year of Assessment (YA 2026).
Key Features
1. Detailed Employment Income
Beyond just your annual salary, the calculator includes specific fields for: - Annual Salary: Your core base pay. - Bonus / Commission: Performance-based variable pay. - Other Income: Any other employment benefits or miscellaneous income.
Calculations update instantly as you type, giving you immediate visibility into your tax liability.
2. Trade & Business Income
For freelancers, sole proprietors, and business owners, we've included a dedicated section for net profit or loss from trades, professions, or vocations.
3. Rental Property Income Helper
Rental income is often complex due to mortgage interest and expense calculations. This tool simplifies it by offering: - Ownership Share: Calculate tax based on your specific percentage of ownership. - Expense Types: Choose between the 15% Deemed Expenses (standard IRAS simplification) or Actual Expenses for manual entry. - Automatic Calculations: The tool handles the gross-to-net math for you.
4. Comprehensive Reliefs & Deductions
The calculator accounts for all major personal reliefs, including: - Earned Income Relief: Automatically adjusted based on your age. - CPF Contribution Relief: A major factor for most employees. - Life Insurance Relief: Correctly restricted based on your CPF contributions. - Donation Relief: Calculated at the standard 2.5x tax deduction rate. - Relief Cap: It automatically applies the $80,000 personal tax relief cap per Year of Assessment.
Advanced UX Functionality
💾 Save & Load
We understand that tax filing involves many numbers that you might not have on hand all at once. - Save Calculation: Export your entire session as a structured JSON file. - Load Calculation: Import a previous save file to immediately populate the form and resume your planning.
🔒 Privacy by Design
Your financial data is sensitive. This tool follows a privacy-first approach: - No Server Storage: Your data is never sent to or stored on our servers. - Local Processing: All calculations and Save/Load logic happen entirely within your browser. - Confidentiality: Your information remains private, and only you have access to the files you save locally.
