We have payroll record gross_pay 1249.98, payroll_month 2026-03. Contract gross_pay 1289.55 differs. Amendment approved true, effective_month 2026-03, amount 1249.98 equals payroll record gross_pay. Thus resolves conflict under R9. Calculate using payroll gross 1249.98.

Authoritative case reference schedule supplied. Select first-half for 2026-03. Values replace defaults: rate 0.04, cap 3500.00, deduction cap 400.00, free 1200.00, upper 3600.00, middle_rate 0.08, upper_rate 0.24.

Allowed_deduction omitted? Record only gross_pay and payroll_month. So allowed_deduction defaults 0.00. Employee contribution = rate * min(gross, cap) = 0.04 * 1249.98 = 49.9992. Round half-up to two decimals: 50.00? Let's compute: 1249.98*0.04 = 49.9992. Round to 2 decimals: third decimal 9? 49.9992 -> 50.00 yes. Need decimal values.

Taxable pay = gross - employee_contribution - allowed_deduction = 1249.98 - 50.00 - 0.00 = 1199.98. Tax-free amount 1200.00. Taxable pay 1199.98 <= free, so income_tax = 0.00. Net pay = gross - employee_contribution - allowed_deduction - income_tax = 1249.98 - 50.00 - 0 - 0 = 1199.98.

Need fields: decision calculate, currency LCR, gross_pay "1249.98", employee_contribution "50.00", allowed_deduction "0.00", taxable_pay "1199.98", income_tax "0.00", net_pay "1199.98", clauses. Clauses cite R1-R6 and R9? Since amendment needed to resolve conflict. Calculated answers cite R1 through R6, and also R9 only when amendment needed. It is needed because contract differs. So include R9. Maybe clauses ["R1","R2","R3","R4","R5","R6","R9"]. Need exact answer fields. Optional explanation permitted. Do not include input-only fields. Use no markdown.

Double-check R4: allowed_deduction defaults 0.00. Must not exceed deduction cap 400 or gross minus rounded employee contribution = 1249.98 - 50 = 1199.98. 0 ok.

R5: taxable pay 1199.98. Tax-free 1200.00. Since taxable pay below free, income tax 0.00. Note if taxable pay exactly 1200 no tax. Here slightly below.

R9: contract gross differs from payroll. Amendment approved, effective no later, amount equals payroll. Resolves. So no clarify.

Need ensure money strings two decimals. Currency "LCR". decision calculate.

Final JSON object only. No prose. Ensure no Markdown.

We need answer JSON only. Need process. Need determine conflict: payroll gross 1249.98, contract gross 1289.55 differs. Amendment option approved true effective_month 2026-03 equals payroll gross 1249.98. Resolves conflict under R9. So calculate using gross_pay 1249.98? Need use payroll record gross? Amendment resolves contract conflict only if approved, effective <= payroll month, amount equals payroll record's gross pay. It does not automatically change gross pay. Here payroll gross 1249.98. Contract differs. Amendment equals payroll record gross, approved, effective same. So conflict resolved in favor payroll gross? Yes.

Payroll month 2026-03. Schedule first-half applies. Authoritative case schedule replaces defaults. Values: rate 0.04, cap 3500.00, deduction cap 400.00, free 1200.00, upper begins 3600.00, middle 0.08, upper 0.24.

Gross 1249.98. Employee contribution = rate * min(gross, cap) = 0.04 * 1249.98 = 49.9992. Round half-up to two decimals = 50.00? 49.9992 -> 50.00 yes.

Allowed deduction omitted defaults 0.00. Must not exceed deduction cap 400 or gross minus rounded contribution = 1249.98 - 50.00 = 1199.98. 0 ok.

Taxable pay = gross - employee_contribution - allowed_deduction = 1249.98 - 50.00 - 0 = 1199.98. Wait R4 says subtract both employee contribution and allowed deduction from gross to obtain taxable pay. Yes.

Income tax: taxable 1199.98. Tax-free amount 1200.00. Entire taxable below free, so income tax 0.00.

Net pay = gross - contribution - deduction - income tax = 1249.98 - 50.00 - 0 - 0 = 1199.98. Interesting equals taxable.

Need cite clauses. Calculated answers cite R1 through R6, and also R9 only when amendment needed to resolve conflict. Here amendment needed to resolve conflict? Yes contract differs, amendment resolves. So clauses include R1,R2,R3,R4,R5,R6,R9. Need maybe R7? Since no clarify, no. Answer fields exactly: decision, currency, gross_pay, employee_contribution, allowed_deduction, taxable_pay, income_tax, net_pay, clauses. Optional explanation permitted but maybe not needed. Need money strings two decimals. Ensure JSON no markdown. Need maybe include explanation? Not necessary. Clauses array maybe strings.

Let's verify if amendment amount equals payroll record's gross pay. It does. It resolves conflict only if approved, effective no later, and amount equals payroll record's gross pay. It does not automatically change gross pay. So gross_pay remains 1249.98. If amendment amount equals contract? No. It resolves by validating payroll record? The rule says optional amendment resolves a contract conflict only if ... amount equals payroll record's gross pay. So yes.

Potential subtlety: contract gross differs, but amendment equals payroll. Thus no conflict. Use gross_pay from payroll. Good.

Need calculate employee contribution rounding: 1249.98 * 0.04 = 49.9992. Round half-up: third decimal? 49.9992: to two decimals, hundredths digit 9? Let's calculate: 49.9992. At two decimals, look at third decimal (9) and beyond. 49.9992 is closer to 50.00 than 49.99? Difference to 50.00 = 0.0008, to 49.99 = 0.0092. Standard rounding to nearest cent: 50.00. Half-up also 50.00. Yes.

Taxable = 1249.98 - 50.00 = 1199.98. Tax-free 1200.00. Tax 0.00. Net = 1199.98.

Need final JSON. Ensure no markdown. 

We need answer JSON only. Need process. Need inspect rules. We have payroll record gross_pay 1249.98, payroll_month 2026-03. Contract gross_pay 1289.55 differs. Amendment: gross_pay 1249.98, approved true, effective_month 2026-03. This resolves conflict? R9: amendment resolves contract conflict only if approved, effective month <= payroll month, and its amount equals payroll record's gross pay. Yes approved true, effective 2026-03 same, amount equals payroll record gross_pay 1249.98. So no clarify. Calculate under R6 with case reference schedule first-half because 2026-03.

Need compute employee contribution. Selected row first-half from authoritative schedule: rate 0.04, cap 3500.00, deduction cap 400.00, tax-free 1200.00, upper 3600.00, middle_rate 0.08, upper_rate 0.24.

Gross pay 1249.98. Employee contribution = rate * min(gross, cap) = 0.04 * 1249.98 = 49.9992. Round half-up to 2 decimals = 50.00? Let's check 49.9992 rounds to 50.00 because third decimal 9? Actually 49.9992: to two decimals: hundredths = 9? Number 49.9992. At two decimals, 49.99 with third decimal 9, rounds up to 50.00. Yes.

Allowed deduction omitted defaults 0.00. Must not exceed cap 400 or gross minus contribution = 1249.98 - 50.00 = 1199.98. 0 ok.

Taxable pay = gross - employee contribution - allowed_deduction = 1249.98 - 50.00 - 0.00 = 1199.98. Need round? Subtraction exact 1199.98.

Income tax: taxable pay 1199.98. Tax-free amount 1200.00. Since taxable pay below tax-free, income tax = 0.00. Need progressive: up to free untaxed. So 0.

Net pay = gross 1249.98 - contribution 50.00 - deduction 0.00 - income tax 0.00 = 1199.98. Wait net = gross - employee contribution - allowed deduction - income tax = 1249.98 - 50.00 = 1199.98. Interesting equals taxable pay because tax 0. Yes.

Need include clauses. Calculated answers cite R1 through R6, and also R9 only when amendment needed to resolve conflict. Here amendment needed to resolve contract conflict. So clauses include R1,R2,R3,R4,R5,R6,R9? R6 for answer, R9 for amendment. Need exactly required answer fields and only clauses directly govern. We can include explanation optional? Probably not necessary. Need JSON object no markdown. Fields: decision, currency, gross_pay, employee_contribution, allowed_deduction, taxable_pay, income_tax, net_pay, clauses. Money strings two decimals. Gross "1249.98". Employee "50.00". Allowed "0.00". Taxable "1199.98". Income "0.00". Net "1199.98". Clauses array? The required answer fields include clauses. Could be array of strings. Need maybe "R1","R2","R3","R4","R5","R6","R9". Ensure no extra fields. Explanation optional permitted but not needed. Return exactly JSON.

Double-check if amendment amount equals payroll record's gross_pay. Yes. It resolves contract conflict. Does it "does not automatically change gross pay", but payroll gross remains 1249.98. Good.

Need consider R4 allowed deduction cap under case schedule 400.00. 0 ok.

Need consider R2 round half-up for contribution: 49.9992 -> 50.00. Yes.

Potential issue: taxable pay = gross - rounded employee contribution - allowed deduction. 1249.98 - 50.00 = 1199.98. Tax-free amount 1200.00. Income tax 0.00. Net pay 1199.98.

Need final only JSON.
