lookup_reference(reference="first-half")The record has gross_pay 4326.01, payroll_month 2026-03, and allowed_deduction 386.64. March 2026 falls in the first half of 2026, so I'll look up the first-half reference row.
Reasoning
The payroll record: - gross_pay: 4326.01 - payroll_month: 2026-03 - allowed_deduction: 386.64 2026-03 is in the second half of 2026 (months 07-12? or first half is 01-06?). Let me check the reference tables. "first-half" likely covers 2026-01 through 2026-06, "second-half" covers 2026-07 through 2026-12. March 2026 is in the first half. Let me look up the first-half reference.

Now I'll compute the exact figures.
Reasoning
First-half row (2026-01 through 2026-06): - rate: 0.07 - cap: 4500.00 - deduction cap: 400.00 - free: 1200.00 - upper: 3600.00 - middle_rate: 0.08 - upper_rate: 0.18 Check R4: allowed_deduction must not exceed min(deduction cap 400.00, gross_pay - rounded contribution). Employee contribution = 0.07 * min(4500.00, 4326.01) = 0.07 * 4326.01 = 302.8207 → round to 302.82. Allowed deduction check: 386.64 ≤ 400.00 ✓. Gross pay minus contribution: 4326.01 - 302.82 = 4023.19. 386.64 ≤ 4023.19 ✓. So allowed_deduction = 386.64. Taxable pay = 4326.01 - 302.82 - 386.64 = 3636.55. Income tax: - Free: 1200.00 → untaxed. - Portion above 1200 up to 3600: 3600 - 1200 = 2400 at 0.08 = 192.00. - Portion above 3600: 3636.55 - 3600 = 36.55 at 0.18 = 6.579 → 6.579. Total = 192.00 + 6.579 = 198.579 → round half up to 198.58. Wait, R2 says "Do not round intermediate bracket products separately before summing income tax." So sum 192.00 + 6.579 = 198.579, round half up → 198.58. Net pay = 4326.01 - 302.82 - 386.64 - 198.58 = ? 4326.01 - 302.82 = 4023.19. 4023.19 - 386.64 = 3636.55. 3636.55 - 198.58 = 3437.97. Let me verify with the calculator.

All inputs are valid and the calculation is complete. The month 2026-03 is covered by the first-half reference row; the deduction 386.64 is within both the 400.00 cap and available pay (4326.01 − 302.82 = 4023.19); tax brackets sum to 198.579, rounded half-up to 198.58.

lookup_reference(reference="first-half")lookup_reference(reference="second-half")Reasoning
The payroll record: - gross_pay: 4326.01 - payroll_month: 2026-03 - allowed_deduction: 386.64 2026-03 is in 2026, so covered. March 2026 is in the second half (months 7-12 are second half? or 1-6 first half, 7-12 second half). Let me check the reference tables. March is month 3, so likely first half. Let me look up both to be safe — actually, I should determine which half March belongs to. Typically first-half = Jan-Jun, second-half = Jul-Dec. Let me look up the first-half reference (and maybe second-half to confirm boundaries). The lookup tool says "Read first-half or second-half payroll reference rates and effective months." I'll look up first-half since March is likely in the first half, but let me check both to be sure of the boundaries. Actually the tool returns effective months, so looking up first-half should tell me which months it covers. Let me call both in parallel to be safe.

Reasoning
Payroll month 2026-03. First-half covers months 2026-01 through 2026-06 (the "months" field shows ["2026-01", "2026-06"] — presumably a range from 2026-01 to 2026-06). March 2026 falls in the first half. So the applicable row: - rate: 0.07 - cap: 4500.00 - deduction cap: 400.00 - free: 1200.00 - upper: 3600.00 - middle_rate: 0.08 - upper_rate: 0.18 Now compute: - Employee contribution = 0.07 * min(4326.01, 4500.00) = 0.07 * 4326.01 = 302.8207 → round half up to 302.82 - Allowed deduction = 386.64. Check: must not exceed deduction cap 400.00, nor gross pay minus rounded contribution = 4326.01 - 302.82 = 4023.19. 386.64 ≤ both. OK. - Taxable pay = 4326.01 - 302.82 - 386.64 = 3636.55 - Income tax: free = 1200, upper = 3600. - Portion up to 1200: untaxed. - Portion 1200 to 3600: 3600 - 1200 = 2400 at 0.08 = 192.00 - Portion above 3600: 3636.55 - 3600 = 36.55 at 0.18 = 6.579 - Total = 192.00 + 6.579 = 198.579 → round half up → 198.58 - Net pay = 4326.01 - 302.82 - 386.64 - 198.58 = 3437.97 Let me verify with the calculator.

Check: must not exceed deduction cap 400.00 (yes, 386.64 ≤ 400.00) and gross pay minus rounded contribution: 4326.01 - 302.82 = 4023.19. 386.64 ≤ 4023.19.

So total = 192.00 + 6.579 = 198.579 → round to 198.58 - Net pay = 4326.01 - 302.82 - 386.64 - 198.58 = 3437.97 Let me verify with the calculator.
