Frequently Asked Questions
How is NIC calculated differently for company directors?
Company directors use an 'annual earnings period' for National Insurance. Their NIC is calculated on the cumulative earnings for the year to date, rather than on each individual payment separately. This prevents NIC avoidance by paying uneven amounts across the year.
What are the NIC thresholds for directors in 2025/26?
Secondary Threshold (employer, 15%): £5,000/year. Primary Threshold (employee, 8%): £12,570/year. Upper Earnings Limit (2% above): £50,270/year. These are the same as for employees but applied on an annual cumulative basis.
What are the director NIC rates for 2025/26?
Employer NIC: 15% on earnings above £5,000 (new rate from April 2025). Employee NIC: 8% on earnings between £12,570 and £50,270, then 2% above £50,270.
How does the optimal salary/dividend strategy change with new NIC rates?
At the new employer NIC rate of 15% and lower Secondary Threshold of £5,000, the optimal salary for a sole director is now around £12,570 (the personal allowance) rather than the old ST of £9,100. The exact figure depends on Employment Allowance eligibility.
Can a director claim Employment Allowance to reduce employer NIC?
A company where the sole director is also the only employee (or the only employee paid above the Secondary Threshold) cannot claim the Employment Allowance. If there is at least one other eligible employee, EA of £10,500 can be claimed.
How does the cumulative method affect directors who join mid-year?
A director who joins mid-year has their NIC calculated using prorated annual thresholds (the annual figures multiplied by weeks as director ÷ 52). This ensures fairness compared to full-year directors.
What happens if a director is paid a lump sum at year end?
Under the annual earnings period, a director's NIC is recalculated at each payment. A large year-end bonus brings cumulative earnings above the primary/secondary thresholds, triggering NIC in that final period. The payroll software adjusts the calculation.
Does the director NIC method apply to dividends?
No. NIC only applies to earnings (salary and any employment income). Dividends are not subject to NIC for directors or shareholders, regardless of the director NIC calculation method.
