Reasoning
Payroll month 2026-09 → second-half. Rate 0.05, cap 4000, deduction cap 400, free 1000, upper 3600, middle 0.12, upper 0.24.

Gross 614.66. Contribution = 0.05 * min(614.66, 4000) = 30.733 → 30.73.
Allowed deduction 175.67 ≤ 400 and ≤ 614.66 - 30.73 = 583.93. OK.
Taxable = 614.66 - 30.73 - 175.67 = 408.26. Below free 1000 → tax 0.00.
Net = 614.66 - 30.73 - 175.67 - 0 = 408.26.
