1. National Insurance Changes: Understanding the Two Components
The NI changes are more complex than initially apparent, consisting of two distinct changes plus the Employment Allowance adjustment. Let’s break down each component:
Component 1: Lower Threshold
- Current threshold: £9,100
- New threshold: £5,000
- Additional earnings subject to NI: £4,100
- New rate applied to this band: 15%
- Cost per employee: £4,100 × 15% = £615
Component 2: Rate Increase on Existing Band
- Current rate: 13.8%
- New rate: 15%
- Increase: 1.2%
- For average salary of £35,000:
- Additional cost: £35,000 × 1.2% = £420 per employee
Employment Allowance Benefit
- Current allowance: £5,000
- New allowance: £10,500
- Additional relief: £5,500
2. Impact Analysis by Company Size
Small Businesses (3 employees)
- Lower threshold cost: 3 × £615 = £1,845
- Rate increase cost: 3 × £420 = £1,260
- Employment Allowance increase: -£5,500 Net effect: £2,395 saving
Medium Businesses (5 employees)
- Lower threshold cost: 5 × £615 = £3,075
- Rate increase cost: 5 × £420 = £2,100
- Employment Allowance increase: -£5,500 Net effect: £325 saving
Larger Businesses (10 employees)
- Lower threshold cost: 10 × £615 = £6,150
- Rate increase cost: 10 × £420 = £4,200
- Employment Allowance increase: -£5,500 Net effect: £4,850 additional cost
3. Quick Guide: Optimal Director Remuneration Strategies
The interaction between Corporation Tax rates and NI creates significantly different outcomes depending on company size. Here’s what you need to know:
Large Companies (Profits over £50,000)
✓ PREFER SALARY when:
- Company qualifies for Employment Allowance (needs at least 2 directors/employees)
- Corporation Tax rate is 26.5%
- Can save up to 4.93% (basic rate) or 3.31% (higher rate)
- Example saving on £20,000: £986.25 (basic rate)
Small Companies (Profits under £50,000)
✓ PREFER DIVIDENDS when:
- Corporation Tax rate is 19%
- Can save up to 2.57% (basic rate) or 4.19% (higher rate)
- Example saving on £20,000: £838.75 (higher rate)
4. Key Decision Factors
1. Company Size Matters
- Large companies: Salary more tax-efficient
- Small companies: Dividends more tax-efficient
2. Employment Allowance Critical
- Must have multiple directors/employees to qualify
- New £10,500 allowance makes salary more attractive for larger companies
3. Tax Rates Comparison
Large Companies:
- Salary route: 28% (basic) / 48% (higher)
- Dividend route: 32.93% (basic) / 51.31% (higher)
4. Small Companies:
- Salary route: 28% (basic) / 48% (higher)
- Dividend route: 25.43% (basic) / 43.81% (higher)
