Reasoning
First-half applies: rate 0.08, cap 4500, deduction 400, free 1200, upper 3000, middle 0.08, upper 0.18. gross 4481.05. contribution = 0.08 * min(4481.05, 4500) = 0.08*4481.05 = 358.484 → 358.48 (round half up: 358.484 → 358.48). allowed deduction 0.00. taxable = 4481.05 - 358.48 - 0 = 4122.57. Tax: free 1200 untaxed. 1200 to 3000 = 1800 * 0.08 = 144. Above 3000: 4122.57-3000 = 1122.57 * 0.18 = 202.0626. Sum = 346.0626 → 346.06. net = 4481.05 - 358.48 - 0 - 346.06 = 3776.51. Check: 4481.05 - 358.48 = 4122.57; -346.06 = 3776.51. ✓

Reasoning
Payroll month 2026-05 → first-half. rate 0.08, cap 4500, deduction 400, free 1200, upper 3000, middle 0.08, upper rate 0.18. gross 4481.05. contribution = 0.08 * min(4481.05, 4500) = 0.08*4481.05 = 358.484 → 358.48. allowed deduction 0.00, ≤ 400 and ≤ gross - contribution = 4122.57. OK. taxable = 4481.05 - 358.48 - 0 = 4122.57. tax: up to 1200 untaxed; 1200→3000 = 1800 * 0.08 = 144.00; above 3000: 4122.57-3000 = 1122.57 * 0.18 = 202.0626. Sum = 144 + 202.0626 = 346.0626 → 346.06 (round half up: 346.0626 → 346.06). net = 4481.05 - 358.48 - 0 - 346.06 = 3776.51. Check: 4481.05 - 358.48 = 4122.57; -346.06 = 3776.51. Yes.

Reasoning
Payroll month 2026-05 -> first-half: rate 0.08, cap 4500, deduction 400, free 1200, upper 3000, middle 0.08, upper 0.18. gross 4481.05, min(gross, 4500) = 4481.05. Contribution = 0.08 * 4481.05 = 358.484 -> 358.48. Allowed deduction 0.00. Taxable = 4481.05 - 358.48 = 4122.57. Tax: up to 1200 untaxed; 1200 to 3000 = 1800 * 0.08 = 144.00; above 3000: 4122.57 - 3000 = 1122.57 * 0.18 = 202.0626. Total = 144 + 202.0626 = 346.0626 -> 346.06. Net = 4481.05 - 358.48 - 0.00 - 346.06 = 3776.51.
