Adjustments Needed to Existing Implementations + +### 1.1 ~~WIS Income-Based Tapering~~ RESOLVED +Implemented exact piecewise linear formulas from CPF Board's +official WIS calculator for all 4 age bands (30-34, 35-44, +45-59, 60+). Each band has multi-segment ramp-up, plateau +($1,700-$2,300), and ramp-down. 7 tests covering plateau, +ramp-up, ramp-down, and boundary cases. + +### 1.2 ~~NSman Relief Categories~~ RESOLVED +Added NsmanStatus enum (5 categories), is_wife_of_nsman and +is_parent_of_nsman inputs. Formula uses select() over enum + +max_() for mutual exclusivity (cannot combine self + wife/parent). +Fixed key_appointment_non_active parameter: $3,000 -> $3,500. + +### 1.3 ~~Dependant Income Threshold Not Enforced~~ RESOLVED +Added spouse_income input variable. spouse_relief.py now checks +spouse_income <= dependant_income_threshold ($4k for 2024, +$8k for 2025). Child/parent reliefs remain simplified (no +individual dependant income tracking). + +### 1.4 ~~WMCR Uses Fixed Amounts Only~~ RESOLVED +Added number_of_children_born_before_2024 input. Formula now +splits: pre-2024 children use rate-based (15%/20%/25% of earned +income), post-2024 children use fixed ($8k/$10k/$12k). + +### 1.5 ~~GSTV MediSave Income Ceiling~~ RESOLVED +Verified: GSTV MediSave has NO assessable income ceiling (unlike +GSTV Cash which has $39,000). The existing implementation is +correct - it checks only citizenship, age >= 65, AV ceiling, and +property count. Source: MOF press releases and GovBenefits.gov.sg. + +### 1.6 ~~PTR Parameters Unused~~ RESOLVED (BY DESIGN) +Added clarifying comment to parenthood_tax_rebate.py explaining +that per-child parameters (parenthood_first_child=$5k, etc.) exist +as reference documentation only. PTR uses ptr_balance input because +PolicyEngine cannot track multi-year carry-forward balances. + +### 1.7 ~~ComCare SMTA~~ RESOLVED (ELIGIBILITY ONLY) +Added comcare_smta_eligible variable using the $800 monthly PCI +benchmark. SMTA benefit amounts are determined by caseworker +assessment (shortfall between income and basic living expenses), +not a fixed formula, so only eligibility is modeled. The $800 PCI +benchmark is officially described as "not a hard threshold" but +is used as a proxy. Tests added to existing ComCare test file. + +### 1.8 ~~Silver Support CPF Savings Check~~ RESOLVED (DOCUMENTED) +Added NOTE comment to silver_support_eligible.py documenting that +real Silver Support also checks lifetime CPF savings. PolicyEngine +cannot model CPF balances, so this check is omitted as a known +limitation. + +--- + +## 2.
