Reasoning
Gross 3872.25, month 2026-04 -> first-half case schedule: rate 0.06, cap 4000, deduction 400, free 1000, upper 3300, middle 0.14, upper_rate 0.24. Contribution = 0.06 * min(3872.25, 4000) = 0.06*3872.25 = 232.335 -> round half up = 232.34. Allowed deduction 61.98 <= 400 and <=3872.25 - 232.34 = 3639.91. OK. Taxable = 3872.25 - 232.34 - 61.98 = 3577.93. Tax: first 1000 untaxed; 3577.93 - 1000 = 2577.93 up to 3300 -> bracket width 2300 (1000 to 3300). Portion above 1000 up to 3300 = 2300 * 0.14 = 322.00. Portion above 3300 = 3577.93 - 3300 = 277.93 * 0.24 = 66.7032. Total = 388.7032 -> 388.70. Net = 3872.25 - 232.34 - 61.98 - 388.70 = 3189.23.

Reasoning
Payroll month 2026-04 → first-half row from case schedule: rate 0.06, cap 4000, deduction 400, free 1000, upper 3300, middle 0.14, upper rate 0.24. Gross 3872.25. Contribution = 0.06 * min(3872.25, 4000) = 0.06 * 3872.25 = 232.335 → round half up = 232.34. Allowed deduction 61.98 ≤ 400, and ≤ gross - contribution = 3872.25 - 232.34 = 3639.91. OK. Taxable = 3872.25 - 232.34 - 61.98 = 3577.93. Tax: free 1000 untaxed. From 1000 to 3300 = 2300 * 0.14 = 322.00. Above 3300: 3577.93 - 3300 = 277.93 * 0.24 = 66.7032. Sum = 388.7032 → round 388.70. Net = 3872.25 - 232.34 - 61.98 - 388.70 = 3189.23. Check: 3872.25 - 232.34 = 3639.91; -61.98 = 3577.93; -388.70 = 3189.23. ✓ Clauses: R1-R6.
