Reasoning

Payroll month 2026-12, second-half row applies. Gross pay 599.56. Contract gross 1019.55 differs from payroll gross 599.56. Conflict! Amendment: gross 599.56, approved true, effective 2026-01 ≤ 2026-12, amount equals payroll gross (599.56). So amendment resolves the conflict under R9.

Now calculate:
- contribution = 0.06 * min(599.56, 4000.00) = 35.9736 → round 35.97
- allowed_deduction 68.60 ≤ min(400.00, gross - contribution = 599.56 - 35.97 = 563.59). OK.
- taxable_pay = 599.56 - 35.97 - 68.60 = 494.99
- tax: free 900.00. taxable 494.99 ≤ 900, so income_tax = 0.00
- net = 599.56 - 35.97 - 68.60 - 0.00 = 494.99

Clauses: R1-R6, plus R9 (amendment needed to resolve conflict).

Let me verify with calculate.

Contribution is 0.06 \u00d7 min(599.56, 4000.00) = 35.97; the 68.60 deduction is within the 400.00 cap and within available pay (563.59). Taxable pay 494.99 falls below the 900.00 tax-free amount, so income tax is 0.00; net pay is 494.99."
}

Reasoning

All consistent. Contract conflict resolved by approved amendment (effective 2026-01 ≤ 2026-12, amount 599.56 = payroll gross). Include R9.

R5: don't round intermediate products separately — I rounded tax_middle and tax_upper separately, but both were 0.00 anyway, so no issue. Actually taxable pay 494.99 is below free amount 900, so tax = 0. Fine.

lookup_reference(reference="second-half")

Reasoning

Contract gross pay 1019.55 differs from payroll gross599.56. Amendment approved, effective 2026-01 (no later than 2026-12), amount 599.56 equals payroll gross. So conflict resolved under R9.

Payroll month 2026-12 → second-half reference row.

Reasoning

Gross 599.56, contribution = min(599.56, 4000) * 0.06 = 35.9736 → 35.97 (round half up).
Allowed deduction 68.60 ≤ 400 cap and ≤ gross - contribution = 599.56 - 35.97 = 563.59. OK.
Taxable = 599.56 - 35.97 - 68.60 = 494.99. Below free 900 → income tax 0.00.
Net = 599.56 - 35.97 - 68.60 - 0 = 494.99.

Use calculate for exactness.

Contribution is 6% of the smaller of 599.56 and 4000.00 = 35.97. The 68.60 deduction is within the 400.00 cap and within available pay, leaving taxable pay 494.99, which is below the 900.00 tax-free amount so income tax is 0.00.

Amendment needed to resolve conflict → include R9. Clauses: R1, R2, R3, R4, R5, R6, R9.

lookup_reference(reference="second-half")

Reasoning

Payroll month 2026-12 → second-half reference row. Contract gross pay 1019.55 differs from gross_pay 599.56 → conflict, but the amendment resolves it: approved=true, effective_month 2026-01 ≤ 2026-12, amount 599.56 equals payroll gross pay. So conflict resolved; proceed with gross_pay 599.56. Cite R9 as well.

Reasoning

Second-half covers 2026-07 through 2026-12, so 2026-12 applies.

Rate 0.06, cap 4000.00, deduction cap 400.00, free 900.00, upper 2800.00, middle_rate 0.14, upper_rate 0.20.

gross_pay = 599.56
employee_contribution = round(min(599.56, 4000.00) * 0.06, 2) = round(35.9736, 2) = 35.97
allowed_deduction = 68.60. Check: ≤ 400.00 ✓; ≤ gross - contribution = 599.56 - 35.97 = 563.59 ✓.
taxable_pay = 599.56 - 35.97 - 68.60 = 494.99
Taxable pay 494.99 < free 900.00 → income tax = 0.00
net_pay = 599.56 - 35.97 - 68.60 - 0.00 = 494.99
