lookup_reference(reference="first-half")

Reasoning

Now I need reference rows. Month 2026-04 is first half. Let's look up first-half.

calculate(program="contribution = round(min(2107.50, 4500.00) * 0.07, 2)\ntaxable = 2107.50 - contribution - 273.91\ntax = round(max(0, min(taxable, 3600.00) - 1000.00) * 0.08 + max(0, taxable - 3600.00) * 0.24, 2)\nnet = 2107.50 - contribution - 273.91 - tax")

Reasoning

Now compute. Gross 2107.50. Contribution = 0.07 * min(2107.50, 4500) = 0.07 * 2107.50 = 147.525 → round half up = 147.53? Wait 147.525 round half up to 2 decimals = 147.53.

Hmm, let me be careful: 2107.50 * 0.07 = 147.525. Round half up → 147.53.

Allowed deduction: 273.91, cap 400.00, also must not exceed gross - contribution = 2107.50 - 147.53 = 1959.97. 273.91 <= 400 and <= 1959.97, ok.

Taxable pay = 2107.50 - 147.53 - 273.91 = 1686.06.

Income tax: taxable 1686.06, free 1000, upper 3600. Since 1686.06 <= 3600, portion above free = 686.06 at middle rate 0.08 = 54.8848 → round 54.88.

Net pay = 2107.50 - 147.53 - 273.91 - 54.88 = 1631.18.

Let me verify with calculate.

Reasoning

Payroll month 2026-04 falls in first-half (2026-01 through 2026-06). So selected row: rate 0.07, cap 4500.00, deduction 400.00, free 1000.00, upper 3600.00, middle_rate 0.08, upper_rate 0.24.

Gross pay = 2107.50
Employee contribution = rate * min(gross, cap) = 0.07 * min(2107.50, 4500) = 0.07*2107.50 = 147.525 → round half up = 147.53? Let's compute: 2107.50*0.07 = 147.525. Round half up to 2 decimals = 147.53.

Allowed deduction = 273.91. Must not exceed deduction cap (400.00) or gross pay minus rounded employee contribution = 2107.50 - 147.53 = 1959.97. 273.91 ≤ 400 and ≤ 1959.97, valid.

Taxable pay = gross - employee contribution - allowed deduction = 2107.50 - 147.53 - 273.91 = 1686.06.

Income tax: taxable pay 1686.06. Free 1000.00 untaxed. Portion above free up to upper boundary 3600.00 uses middle rate. 1686.06 - 1000 = 686.06, which is below 3600. So middle rate 0.08 * 686.06 = 54.8848 → round = 54.88.

Net pay = gross - employee contribution - allowed deduction - income tax = 2107.50 - 147.53 - 273.91 - 54.88 = 1631.18.

Let me verify with calculate.

Actually let me do all arithmetic via calculate.

Reasoning

Payroll month 2026-04 falls in first-half (2026-01 to 2026-06). So use first-half row.

rate = 0.07, cap = 4500.00, deduction cap = 400.00, free = 1000.00, upper = 3600.00, middle_rate = 0.08, upper_rate = 0.24.

gross_pay = 2107.50, allowed_deduction = 273.91.

Employee contribution = rate * min(gross, cap) = 0.07 * min(2107.50, 4500.00) = 0.07 * 2107.50 = 147.525 → round half up = 147.53.

Allowed deduction check: must not exceed deduction cap (400.00) and gross pay minus rounded employee contribution (2107.50 - 147.53 = 1959.97). 273.91 ≤ 400 and ≤ 1959.97. OK.

Taxable pay = gross - employee contribution - allowed deduction = 2107.50 - 147.53 - 273.91 = 1686.06.

Income tax: taxable pay 1686.06. Free = 1000.00 untaxed. Portion above free up to upper (3600): 1686.06 - 1000 = 686.06 at middle rate 0.08 = 54.8848 → not rounded separately. Above upper: none.

Total income tax = 54.8848 → round = 54.88.

Net pay = gross - contribution - deduction - tax = 2107.50 - 147.53 - 273.91 - 54.88 = 1631.18.

Let me compute: 2107.50 - 147.53 = 1959.97. -273.91 = 1686.06. -54.88 = 1631.18.

Let me verify with calculator.
