Reasoning
Gross 5000.02, month 2026-05, first-half row: rate 0.06, cap 5000.00, deduction cap 400.00, free 1100, upper 3300, middle 0.10, upper rate 0.18.

Contribution: min(5000.02, 5000.00) = 5000.00 × 0.06 = 300.00.

Allowed deduction 0.00.

Taxable: 5000.02 - 300.00 - 0.00 = 4700.02.

Tax: 0-1100 untaxed. 1100 to 3300: 2200 × 0.10 = 220.00. Above 3300: 4700.02 - 3300 = 1400.02 × 0.18 = 252.0036. Sum: 220.00 + 252.0036 = 472.0036 → 472.00.

Net: 5000.02 - 300.00 - 0.00 - 472.00 = 4228.02.

Reasoning
Gross 5000.02, month 2026-05 → first-half custom: rate 0.06, cap 5000.00, deduction 400, free 1100, upper 3300, middle 0.10, upper 0.18.

Contribution = 0.06 × min(5000.02, 5000.00) = 0.06 × 5000 = 300.00.

Allowed deduction 0.00, within cap 400 and ≤ gross-contribution = 4700.02. Fine.

Taxable = 5000.02 - 300.00 - 0.00 = 4700.02.

Tax: free 1100 untaxed. Middle bracket 1100→3300 = 2200 × 0.10 = 220.00. Upper: 4700.02 - 3300 = 1400.02 × 0.18 = 252.0036. Total = 472.0036 → 472.00 (round half up: 472.0036 → 472.00).

Net = 5000.02 - 300.00 - 0.00 - 472.00 = 4228.02.

Clauses: R1-R6. No amendment.

Reasoning
We need process one payroll record.

Need calculate under R6.

Payroll month 2026-05 → first-half. Authoritative schedule: rate 0.06, cap 5000.00, deduction cap 400.00, free 1100.00, upper 3300.00, middle 0.10, upper 0.18.

gross_pay = 5000.02
allowed_deduction = 0.00

Employee contribution = rate * min(gross, cap) = 0.06 *5000.00 = 300.00.

Taxable pay = 5000.02 - 300.00 - 0.00 = 4700.02.

Income tax: free 1100 untaxed. Middle bracket1100 to 3300 = 2200 @ 0.10 = 220.00. Upper: 4700.02 - 3300 = 1400.02 @ 0.18 = 252.0036. Total = 472.0036 → round half up = 472.00 (since .0036).472.00.

Net pay = 5000.02 - 300.00 - 0.00 - 472.00 = 4228.02.

Check allowed deduction cap: 0.00 ≤ 400.00 and ≤ gross - contribution = 4700.02. Fine.

Clauses: R1-R6. Since no amendment needed.
