This guide provides a strategic overview of the progressive tax rates, essential tax reliefs to reduce your chargeable income, and how to utilize the No-Filing Service (NFS) effectively.
๐ YA 2026 Tax Season: Deadlines & Rates

Resident Tax Rates (Progressive)
Your chargeable income determines your rate. The first $20,000 is tax-free.
- First $20,000: 0% tax.
- Next $10,000: 2% rate.
- Next $10,000: 3.50% rate.
- Above $320,000: Capped at 24% (Top Marginal Rate).
- *Non-residents are taxed at a flat rate (usually 24%) or progressive rates, whichever is higher.
How to File via Singpass
Most employees are under the Auto-Inclusion Scheme (AIS), meaning your employer sends income data directly to IRAS.
- No-Filing Service (NFS): If you receive an NFS letter via SMS/Post, you do not need to file unless you have additional income/reliefs to declare.
- Manual Filing: Required for freelancers, commission agents, and property landlords.
๐ก๏ธMaximizing Tax Reliefs (Reduce Liability)
The total personal income tax relief cap is currently set at $80,000 per Year of Assessment. Smart taxpayers leverage Supplementary Retirement Scheme (SRS) top-ups and family rebates to lower their chargeable income legally.
SRS Contribution Relief
Every dollar topped up into your SRS account reduces your taxable income by a dollar. (Cap: $15,300 for Citizens/PRs, $35,700 for Foreigners). *Must have been done by 31 Dec 2025 for YA 2026.
Parenthood Tax Rebate (PTR)
One-time rebate for parents. $5,000 for 1st child, $10,000 for 2nd. This is a direct tax offset, not just a relief.
Course Fees Relief
Claim up to $5,500 for approved courses relevant to your employment. Upskilling pays off in tax savings.
๐ก Hidden Deductions for Self-Employed
Freelancers, Gig Workers, and Property Agents often miss these allowable business expenses.
Home Office
If you work from home, you can claim a portion of your electricity and WiFi bills as business expenses based on floor area.
Private Car Rules
Warning: Private car expenses (even for business) are generally NOT deductible. Use public transport/Grab receipts instead.
60/40 Rule
Private Hire Car (PHC) drivers can opt for a fixed expense ratio (60% deemed expenses) instead of filing manual receipts.
