"explanation": "The authoritative second-half row for 2026-07 applies. The employee contribution is 0.07 \u00d7 1778.50 = 124.495, rounded to 124.50. The approved amendment effective 2026-04 matches the payroll gross pay, resolving the contract conflict under R9. Tax is 554.00 \u00d7 0.14 = 77.56."
}
Reasoning
Payroll month 2026-07 → second-half: rate 0.07, cap 4000.00, deduction cap 400.00, free 1100.00, upper 3300.00, middle 0.14, upper rate 0.22. Gross 1778.50. Contribution = 0.07 * min(1778.50, 4000.00) = 0.07*1778.50 = 124.495 → round half up = 124.50? 1778.50 * 0.07 = 124.495. Round half up to 2 dp = 124.50. Allowed deduction 0.00, within cap 400.00 and within gross-contribution = 1654.00. OK. Taxable = 1778.50 - 124.50 - 0.00 = 1654.00. Tax: above free 1100: 1654 - 1100 = 554.00 at 0.14 = 77.56. Above3300: none. Income tax = 77.56. Net = 1778.50 - 124.50 - 0.00 - 77.56 = 1576.44. Contract conflicts (2254.61 vs 1778.50), amendment approved, effective 2026-04 ≤ 2026-07, amount equals payroll gross → resolves. Cite R9. Clauses: R1, R2, R3, R4, R5, R6, R9.

Reasoning
Payroll month 2026-07 -> second-half row: rate 0.07, cap 4000.00, deduction cap 400.00, free 1100.00, upper 3300.00, middle 0.14, upper 0.22. Gross 1778.50. Contract 2254.61 differs from gross. Amendment approved, effective 2026-04 <= 2026-07, amount 1778.50 equals payroll gross. So amendment resolves conflict. Cite R9. Contribution = 0.07 * min(1778.50, 4000.00) = 0.07*1778.50 = 124.495 -> round half up -> 124.50 (two decimals).1778.50*0.07 = 124.495 exactly. Round half up -> 124.50. Allowed deduction 0.00. Taxable = 1778.50 - 124.50 - 0.00 = 1654.00. Tax: free 1100. Middle portion: 1654.00 - 1100 = 554.00 at 0.14 = 77.56. Upper portion: 0. Tax = 77.56. Net = 1778.50 - 124.50 - 0.00 - 77.56 = 1576.44. Clauses: R1-R6 and R9.

Reasoning
Second-half applies. rate 0.07, cap 4000, deduction cap 400, free 1100, upper 3300, middle 0.14, upper 0.22. Contribution = 0.07 * min(1778.50, 4000) = 124.495 → 124.50 (round half up). Allowed deduction 0.00. Taxable = 1778.50 - 124.50 - 0.00 = 1654.00. Tax: 1654 - 1100 = 554 * 0.14 = 77.56. Net = 1778.50 - 124.50 - 0 - 77.56 = 1576.44. Contract gross pay 2254.61 differs from 1778.50, but amendment approved, effective 2026-04 <= 2026-07, amount 1778.50 equals payroll gross. So conflict resolved. Cite R9.
