252## Section 9 -- Common Payroll Patterns
253 
254### Pattern 1 -- Standard Monthly Employee (Category A)
255 
256Gross salary £3,500/month. Tax code 1257L.
257 
2581. PAYE: (£3,500 × 12 - £12,570) × 20% ÷ 12 = £595.50/month (cumulative calc)
2592. Employee NIC: (£3,500 - £1,048) × 8% = £196.16/month
2603. Employer NIC: (£3,500 - £417) × 15% = £462.45/month
2614. Auto-enrolment pension (employee): (£3,500 - £520) × 5% = £149.00
2625. Auto-enrolment pension (employer): (£3,500 - £520) × 3% = £89.40
263 
264### Pattern 2 -- Director NIC Calculation
265 
266Directors may use either the annual earnings period method (standard) or the alternative method (cumulative per pay period). The annual method defers NIC until cumulative earnings exceed the annual threshold. Most payroll software defaults to the annual method; the alternative method requires explicit election.
267 
268### Pattern 3 -- Starter with No P45
269 
270Apply HMRC starter checklist. Use one of three statements:
271- A: First job since 6 April -- apply 1257L on cumulative basis
272- B: Currently has another job -- apply BR
273- C: Has another source of income -- apply BR
274 
275### Pattern 4 -- Statutory Payment Recovery
276 
277Standard employers recover 92% of SMP/SAP/ShPP/SPBP/SNCP. Small employers (Class 1 NIC ≤ £45,000 in qualifying year) recover 100% + 9% compensation (109% total from Apr 2026). SSP cannot be recovered.
