Reasoning

March 2026 is in first-half (2026-01 to 2026-06). Good.

Inputs:
- gross_pay = 1430.25
- payroll_month = 2026-03
- allowed_deduction = 115.82
- contract_gross_pay = 1430.25 (matches gross_pay, no conflict)

Reference row first-half:
- rate = 0.08
- cap = 4000.00
- deduction cap = 400.00
- free = 1200.00
- upper = 3000.00
- middle_rate = 0.14
- upper_rate = 0.18

Employee contribution = rate * min(gross, cap) = 0.08 * min(1430.25, 4000.00) = 0.08 * 1430.25 = 114.42.

Allowed deduction = 115.82. Check: must not exceed deduction cap (400.00) or gross pay minus rounded employee contribution (1430.25 - 114.42 = 1315.83). 115.82 <= 400 and <= 1315.83. OK.

Taxable pay = gross - employee contribution - allowed deduction = 1430.25 - 114.42 - 115.82 = 1200.01.

Income tax: taxable pay 1200.01. Free 1200.00. Portion above free = 0.01, up to upper boundary 3000.00 uses middle rate 0.14. So tax = 0.01 * 0.14 = 0.0014 → round half up = 0.00.

Net pay = gross - employee contribution - allowed deduction - income tax = 1430.25 - 114.42 - 115.82 - 0.00 = 1200.01.

Let me verify with calculate.

lookup_reference(reference="first-half")

Reasoning

Payroll month 2026-03, first half (Jan-Jun). Need reference row for first-half.

Contract gross_pay = 1430.25 matches gross_pay, so no conflict.

Lookup reference first-half.

Reasoning

Now compute.

gross_pay = 1430.25
employee_contribution = rate * min(gross, cap) = 0.08 * min(1430.25, 4000.00) = 0.08 * 1430.25 = 114.42
allowed_deduction = 115.82. Must not exceed deduction cap 400.00 nor gross - employee contribution = 1430.25 - 114.42 = 1315.83. 115.82 <= 400 and <= 1315.83. OK.

taxable_pay = 1430.25 - 114.42 - 115.82 = 1200.01
income_tax: free 1200.00 untaxed. taxable pay 1200.01, portion above free = 0.01 up to upper 3000 -> middle rate 0.14. 0.01*0.14 = 0.0014 -> round 0.00.
income_tax = 0.00
net_pay = 1430.25 - 114.42 - 115.82 - 0.00 = 1200.01

Let me verify with calculate.

lookup_reference(reference="first-half")

Reasoning

Payroll month 2026-03, first half. Contract gross_pay matches gross_pay, so no conflict. Need reference row for first-half.

Reasoning

Month 2026-03 is in first-half (2026-01 to 2026-06).

Row: rate 0.08, cap 4000.00, deduction cap 400.00, free 1200.00, upper 3000.00, middle_rate 0.14, upper_rate 0.18.

Gross pay = 1430.25.

Employee contribution = 0.08 * min(1430.25, 4000.00) = 0.08 * 1430.25 = 114.42.

Allowed deduction = 115.82. Check cap: must not exceed deduction cap 400.00 or gross pay minus rounded employee contribution = 1430.25 - 114.42 = 1315.83. 115.82 ≤ 400 and ≤ 1315.83. OK.

Taxable pay = 1430.25 - 114.42 - 115.82 = 1200.01.

Income tax: taxable pay up to free 1200.00 untaxed. Portion above up to upper 3000.00 uses middle rate. Taxable 1200.01, so portion above free = 0.01 at 0.14 = 0.0014 → round to 0.00. Total income tax = 0.00.

Net pay = 1430.25 - 114.42 - 115.82 - 0.00 = 1200.01.

Let me compute exactly with calculator.

Contribution = 0.08 x 1430.25 = 114.42. Deduction 115.82 is within the 400.00 cap and within gross minus contribution (1315.83). Taxable = 1430.25 - 114.42 - 115.82 = 1200.01; only 0.01 exceeds the 1200.00 free amount, giving tax 0.0014 -> 0.00. Net = 1200.01. Contract gross matches, so no amendment is needed."
}

Reasoning

All good. Contract matches gross pay, no conflict. Return calculate.

Clauses: R1-R6 (no amendment needed). Contract value matches, no R9 needed.
