Payroll month 2026-05, first-half? Let me check reference. Need to look up first-half and second-half. 2026-05 is May, which is in first half presumably (Jan-Jun). Let me look up both.

Reasoning

Payroll month 2026-05 falls in first-half. So use first-half row: rate 0.04, cap 5000.00, deduction 400.00, free 1000.00, upper 3600.00, middle_rate 0.10, upper_rate 0.24.

Gross pay = 8370.45.

Employee contribution = rate * min(gross, cap) = 0.04 * min(8370.45, 5000.00) = 0.04 * 5000.00 = 200.00.

Allowed deduction: given 370.62. Must not exceed deduction cap (400.00) or gross pay minus rounded employee contribution (8370.45 - 200.00 = 8170.45). 370.62 <= 400 and <= 8170.45. OK.

Taxable pay = gross - employee contribution - allowed deduction = 8370.45 - 200.00 - 370.62 = 7799.83.

Income tax: progressive marginal.
Free amount 1000.00 untaxed.
Portion above free up to upper boundary 3600.00 uses middle rate 0.10. That's (3600 - 1000) = 2600.00 * 0.10 = 260.00.
Portion above upper boundary uses upper rate 0.24: (7799.83 - 3600) = 4199.83 * 0.24 = 1007.9592 → round... but R2 says do not round intermediate bracket products separately before summing. So compute total: 260.00 + 4199.83*0.24 = 260.00 + 1007.9592 = 1267.9592 → round half up to 1267.96.

Net pay = gross - employee contribution - allowed deduction - income tax = 8370.45 - 200.00 - 370.62 - 1267.96 = 6531.87.

Let me compute with calculate.

Reasoning

Month 2026-05 falls in first-half (2026-01 through 2026-06). Good.

Now calculate.

gross_pay = 8370.45
contribution rate = 0.04, cap = 5000.00
employee_contribution = round(min(8370.45, 5000.00) * 0.04, 2) = round(5000 * 0.04) = 200.00

allowed_deduction = 370.62
Check: must not exceed deduction cap (400.00) nor gross pay minus rounded employee contribution (8370.45 - 200.00 = 8170.45). 370.62 <= 400 and <= 8170.45. OK.

taxable_pay = 8370.45 - 200.00 - 370.62 = 7799.83

income tax:
free = 1000.00, upper = 3600.00
Taxable pay up to free untaxed. Portion above free up to upper boundary uses middle rate 0.10. Portion above upper boundary uses upper rate 0.24.

middle bracket: from 1000 to 3600 = 2600.00 * 0.10 = 260.00
upper bracket: above 3600 = 7799.83 - 3600 = 4199.83 * 0.24 = 1007.9592

total = 260.00 + 1007.9592 = 1267.9592 → round half up = 1267.96

net_pay = 8370.45 - 200.00 - 370.62 - 1267.96 = 6531.87

Let me compute with calculator.

Reasoning

Month 2026-05 covered by first-half (2026-01 to 2026-06).

Now compute.

gross_pay = 8370.45
contribution rate = 0.04, cap = 5000.00
employee_contribution = 0.04 * min(8370.45, 5000.00) = 0.04 * 5000.00 = 200.00

allowed_deduction = 370.62. Check cap: deduction cap 400.00, and gross minus rounded contribution = 8370.45 - 200.00 = 8170.45. 370.62 <= 400.00 and <= 8170.45. OK.

taxable_pay = 8370.45 - 200.00 - 370.62 = 7799.83

income tax: free 1000.00, upper 3600.00, middle 0.10, upper 0.24.
Portion up to free: 1000 untaxed.
Portion above free up to upper boundary 3600: (3600 - 1000) = 2600 at 0.10 = 260.00
Portion above 3600: 7799.83 - 3600 = 4199.83 at 0.24 = 1007.9592
Total = 260 + 1007.9592 = 1267.9592 → round 1267.96

net_pay = 8370.45 - 200.00 - 370.62 - 1267.96 = 6531.87

Let me compute via tool.

Tool

{
  "results": {"contribution": "200.00", "taxable": "7799.83", "middle": "260.00", "upper": "1007.96", "tax": "1267.96", "net": "6531.87"}

  "net_pay": "6531.87",
  "clauses": ["R1", "R2", "R3", "R4", "R5", "R6"]
}

Reasoning

Note: R2 says do not round intermediate bracket products separately before summing income tax. So I should compute middle and upper without rounding then sum then round. Let me redo: middle = 2600*0.10 = 260.00 exactly. upper = 4199.83*0.24 = 1007.9592. Sum = 1267.9592 → round half up = 1267.96. Same result. Good.

Final answer.
