All SCs, regardless of income, are eligible for CHAS. The CHAS benefits will be tiered according to household monthly income or Annual Value (AV) of home, as indicated in the below table:
CHAS medical subsidies for different card types
CHAS Criteria | CHAS Green | CHAS Orange | CHAS Blue |
|---|---|---|---|
Household monthly income per person (for households with income)1 | Above $2,300 | $1,501 - $2,300 | $1,500 and below |
Annual Value (AV) of home (for households with no income)2 | Above $31,000 | $21,001 - $31,000 | $21,000 and below |
Effective as of 1 Jan 2025 2 Annual Value is the estimated gross annual rent of a property if it were to be rented out, excluding furnishings and maintenance fees. It is determined by IRAS, and may be checked via mytax.iras.gov.sg. Subsidy levels in 2025 will be determined using 2024 Annual Values. Existing CHAS cardholders who are eligible for a CHAS card with higher subsidies as a result of the revision of AV thresholds from 1 Jan 2025 and with no changes to household details will be automatically issued with new CHAS cards. New cards will be progressively issued in the weeks ahead after 1 Jan 2025. | |||
