Reasoning

Let me work through this payroll record.

Input:
- gross_pay: "1117.86"
- payroll_month: "2026-12"
- allowed_deduction: "128.44"
- contract gross_pay: "1117.86" (matches, no conflict)
- Case reference schedule: second-half row applies for 2026-07 through 2026-12:
  - rate: 0.08
  - cap: 4000.00
  - deduction: 400.00
  - free: 900.00
  - upper: 3000.00
  - middle_rate: 0.08
  - upper_rate: 0.24

Steps:
1. Employee contribution (R3): rate 0.08 × min(1117.86, 4000.00) = 0.08 × 1117.86 = 89.4288 → round to 89.43.
2. Allowed deduction check (R4): 128.44 ≤ 400.00 (cap) and ≤ gross − contribution = 1117.86 − 89.43 = 1028.43. 128.44 ≤ 1028.43. OK.
3. Taxable pay (R4): 1117.86 − 89.43 − 128.44 = 900. - wait: 1117.86 − 89.43 = 1028.43; 1028.43 − 128.44 = 899.99. Taxable pay = 899.99.
4. Income tax (R5): taxable 899.99 vs free 900.00. Taxable pay up to tax-free amount is untaxed. 899.99 ≤ 900.00, so tax = 0.00.
5. Net pay (R6): 1117.86 − 89.43 − 128.44 − 0.00 = 899.99.

Check: 1117.86 − 89.43 = 1028.43; 1028.43 − 128.44 = 899.99; − 0.00 = 899.99. Net pay = 899.99.

Citations: R1 (row selection, schedule), R2 (rounding), R3 (contribution), R4 (deduction and taxable pay), R5 (tax), R6 (net pay). No amendment needed since contract matches gross pay, so no R9.

Reasoning

Let me work through this payroll calculation.

Inputs:
- gross_pay: 1117.86
- payroll_month: 2026-12
- allowed_deduction: 128.44
- Contract gross_pay: 1117.86 (matches, no conflict)
- Case reference schedule: second-half row applies for 2026-12:
  - rate: 0.08
  - cap: 4000.00
  - deduction cap: 400.00
  - free: 900.00
  - upper: 3000.00
  - middle_rate: 0.08
  - upper_rate: 0.24

Steps:

R3: Employee contribution = rate × min(gross, cap) = 0.08 × min(1117.86, 4000.00) = 0.08 × 1117.86 = 89.4288 → round half up to 89.43.

R4: allowed_deduction = 128.44. Check: must not exceed deduction cap 400.00 (yes, 128.44 ≤ 400.00), and must not exceed gross pay minus rounded employee contribution = 1117.86 − 89.43 = 1028.43. 128.44 ≤ 1028.43, OK.

Taxable pay = gross − contribution − deduction = 1117.86 − 89.43 − 128.44 = 899.99.

Let me compute: 1117.86 − 89.43 = 1028.43. 1028.43 − 128.44 = 899.99.

R5: Income tax:
- Taxable pay 899.99 ≤ free 900.00, so all untaxed. Tax = 0.00.

R6: Net pay = gross − contribution − deduction − tax = 1117.86 − 89.43 − 128.44 − 0.00 = 899.99.

Fields:
- decision: calculate
- currency: LCR
- gross_pay: "1117.86"
- employee_contribution: "89.43"
- allowed_deduction: "128.44"
- taxable_pay: "899.99"
- income_tax: "0.00"
- net_pay: "899.99"
- clauses: R1, R2, R3, R4, R5, R6 (and R1 for selecting the row via schedule). No amendment needed since contract matches gross pay, so no R9.

Explanation optional — I can include a brief one. The instructions say an optional explanation string is permitted. I'll include a short one.

Reasoning

Let me work through this payroll case.

Inputs:
- gross_pay: 1117.86
- payroll_month: 2026-12
- allowed_deduction: 128.44
- contract gross_pay: 1117.86 (matches, no conflict)
- Case reference schedule supplied: second-half row applies for 2026-12.

Second-half schedule:
- rate: 0.08
- cap: 4000.00
- deduction: 400.00
- free: 900.00
- upper: 3000.00
- middle_rate: 0.08
- upper_rate: 0.24

Step 1: Employee contribution (R3): rate × min(gross, cap) = 0.08 × min(1117.86, 4000.00) = 0.08 × 1117.86 = 89.4288 → round to 89.43.

Step 2: Allowed deduction check (R4): deduction cap 400.00; gross minus rounded contribution = 1117.86 − 89.43 = 1028.43. Allowed deduction 128.44 ≤ 400.00 and ≤ 1028.43. OK.

Step 3: Taxable pay (R4): gross − contribution − deduction = 1117.86 − 89.43 − 128.44 = 899.99.

Let me compute: 1117.86 − 89.43 = 1028.43. 1028.43 − 128.44 = 899.99.

Step 4: Income tax (R5): taxable 899.99 ≤ free 900.00, so all untaxed. Tax = 0.00.

Step 5: Net pay (R6): gross − contribution − deduction − tax = 1117.86 − 89.43 − 128.44 − 0.00 = 899.99.
