NIC Planning: Employed vs Self-Employed and Remuneration Choices

Updated 11 October 2026 · Fact-checked

NIC planning compares the total national insurance cost of different ways to earn or pay income. Employment costs both employee and employer Class 1. Self-employment costs only Class 4. Dividends carry no NIC. Benefits carry employer Class 1A only. Compute each option's NIC and income tax, then compare the net cash after all taxes.

Understand NIC Planning: Employed vs Self-Employed and Remuneration

Every way of paying someone has its own NIC cost. Your job in ATX is to put a number on each route and recommend the cheapest, after income tax and corporation tax as well.

Employment carries two layers. The employee pays Class 1 at 8% on earnings between £12,570 and £50,270, and 2% above that. The employer pays Class 1 at 15% on earnings above £5,000. The employer's NIC is a real cost to the business, so it reduces what can be paid to the worker.

Self-employment carries only Class 4 for the individual: 6% on profits between £12,570 and £50,270 and 2% above. There is no employer cost. So on the same £ of income, self-employment is much cheaper for NIC. But status is decided by the facts, not by choice. A worker cannot simply label themselves self-employed to save NIC.

Remuneration choices matter for owner-managed companies. Salary and bonus attract employer and employee NIC. Dividends attract no NIC, but they are paid from profits that have already borne corporation tax (19% small profits rate, 25% main rate, with marginal relief between £50,000 and £250,000), and they are taxed at the dividend rates of 8.75%, 33.75% or 39.35% after the £500 dividend nil rate band. Benefits in kind attract employer Class 1A at 15% and no employee NIC, but the employee is still taxed on the benefit.

So the cheapest route is not always the dividend. For a higher rate taxpayer, a bonus can leave slightly more net cash than a dividend, because the company gets a deduction for the bonus and its employer NIC. Always calculate. Do not assume.

Key rules to remember

Employee Class 1 NIC
0% to £12,570; 8% on £12,571 to £50,270; 2% above £50,270
Annual figures. Paid by the employee on earnings.
Employer Class 1 NIC
15% × (earnings − £5,000)
No NIC below £5,000. Deductible against trading profits. Employment allowance of £10,500 may reduce the bill if the employer is eligible.
Class 1A NIC
15% × taxable benefits
Employer only. No employee NIC on benefits.
Class 4 NIC
6% on profits £12,571 to £50,270; 2% above £50,270
Self-employed only. Nil on profits up to £12,570.
Gross pay for a fixed employer cost
Gross salary = Total cost ÷ 1.15
Use when the employer's NIC is at the 15% rate and the earnings are already above £5,000.
Dividend route net cash
Profit × (1 − CT rate) × (1 − dividend tax rate)
No NIC. Dividend rates are 8.75%, 33.75% and 39.35%. First £500 of dividends is at nil rate.

How to solve NIC Planning: Employed vs Self-Employed and Remuneration questions

Use this for any question that asks you to compare the NIC or total tax cost of different ways to earn or pay income.

  1. 1Identify the options and the taxpayer. Note whether it is an individual or a company, and the person's other income and tax band.
  2. 2Check status first if employed versus self-employed is in question. NIC follows the correct status, not preference.
  3. 3Fix a common base: the same pre-tax profit, or the same total cost to the payer. Compare like with like.
  4. 4Compute NIC for each option: employee and employer Class 1, Class 1A, or Class 4, using the bands in the tax tables.
  5. 5Compute income tax, and corporation tax where a company is involved. Remember the company deduction for salary, bonus, benefits and employer NIC.
  6. 6Compute net cash to the individual under each option, or the total tax cost.
  7. 7State the difference in £ and recommend the best option. Mention non-tax points such as pension, state benefits, cash flow or risk.
  8. 8Show all workings, round to the nearest £, and state your assumptions.

Quickest way: Net cash per £10,000 of pre-tax profit

When to use it: Use for owner-manager questions comparing salary, bonus and dividends under time pressure.

  1. Take the company's profit before the payment as the base.
  2. For salary or bonus: divide by 1.15 to get gross pay. Apply income tax and 2% (or 8%) employee NIC. Keep the remainder.
  3. For dividends: deduct corporation tax at the relevant rate. Apply the dividend tax rate to the dividend.
  4. For benefits: Class 1A is 15% of the benefit value. Add the employee's income tax on the benefit.
  5. Compare the net amounts. Add a line on any other factor, such as the £500 dividend nil rate band or pension planning.

Common mistakes in NIC Planning: Employed vs Self-Employed and Remuneration

  • Ignoring employer NIC when comparing salary with self-employment.

    Students only think about the worker's own deductions.

    Fix: Always list employee and employer Class 1 separately. Employer NIC is 15% above £5,000.

  • Saying dividends are always better than salary because they carry no NIC.

    It is a common rule of thumb that ignores corporation tax.

    Fix: Dividends are paid from taxed profits and are not deductible. Compute both routes. For a higher rate taxpayer, a bonus can give more net cash.

  • Charging employee NIC on benefits in kind.

    Benefits are confused with earnings.

    Fix: Benefits attract only employer Class 1A at 15%. The employee pays income tax but no NIC on them.

  • Using Class 4 bands for employees or Class 1 bands for sole traders.

    The two sets of bands look similar.

    Fix: Class 1 employee rates are 8% and 2%. Class 4 rates are 6% and 2%. Check which class applies before you calculate.

  • Recommending self-employment without discussing status.

    The NIC saving looks attractive.

    Fix: State that HMRC looks at the facts of the working relationship. Artificial arrangements risk back-taxation and penalties.

  • Forgetting the tax deduction on employer NIC and salary for the company.

    Students stop at NIC and miss corporation tax.

    Fix: Salary, bonus and employer NIC are deductible. Include the corporation tax saving or compare on a pre-tax profit base.

Worked examples

Example 1

Ravi will earn £60,000 a year. Compare the total NIC if he is (a) an employee paid a salary of £60,000 or (b) a sole trader with taxable profits of £60,000. Ignore the employment allowance.

Show the solution
  1. (a) Employee Class 1: £12,571 to £50,270 is £37,700 × 8% = £3,016.
  2. Above £50,270: £60,000 − £50,270 = £9,730 × 2% = £195 (rounded from £194.60).
  3. Total employee NIC = £3,016 + £195 = £3,211.
  4. Employer Class 1: (£60,000 − £5,000) = £55,000 × 15% = £8,250.
  5. Total NIC under employment = £3,211 + £8,250 = £11,461.
  6. (b) Class 4: £37,700 × 6% = £2,262.
  7. Above £50,270: £9,730 × 2% = £195.
  8. Total Class 4 = £2,262 + £195 = £2,457.
  9. Difference: £11,461 − £2,457 = £9,004.

Answer: Employment gives total NIC of £11,461 (£3,211 employee and £8,250 employer). Self-employment gives £2,457 of Class 4. The self-employed route is £9,004 cheaper, but only if Ravi genuinely is self-employed on the facts.

Example 2

Mina is the director of a company that has £10,000 of profit before paying her. She is a higher rate taxpayer with income well above £50,270, and her dividend nil rate band is already used. The company pays corporation tax at 25%. Compare the net cash she receives if the company (a) pays a bonus costing £10,000 in total including employer NIC, or (b) pays a dividend from the profit after corporation tax. Round to the nearest £.

Show the solution
  1. (a) Bonus: total cost £10,000 = gross bonus × 1.15.
  2. Gross bonus = £10,000 ÷ 1.15 = £8,696 (employer NIC £1,304).
  3. Mina pays income tax at 40% and employee NIC at 2%, so 42% in total.
  4. Tax and NIC = £8,696 × 42% = £3,652 (£8,695.65 × 42% = £3,652.17).
  5. Net cash = £8,696 − £3,652 = £5,043.
  6. The bonus and employer NIC are deductible, so the company has no corporation tax on this £10,000.
  7. (b) Dividend: corporation tax = £10,000 × 25% = £2,500.
  8. Dividend = £10,000 − £2,500 = £7,500.
  9. Income tax at 33.75% = £7,500 × 33.75% = £2,531 (£2,531.25). No NIC.
  10. Net cash = £7,500 − £2,531 = £4,969 (£4,968.75).

Answer: The bonus gives Mina net cash of £5,043. The dividend gives £4,969. For a higher rate taxpayer on these rates the bonus is about £74 better per £10,000 of profit, even though the dividend avoids NIC. The result differs for basic rate taxpayers and for additional rate taxpayers, so always compute it. Also consider her pension and state benefit position.

Exam tips

  • Set out a clear table or layout for each option and total the NIC and tax. Marks go for method even if a figure is wrong.
  • Use the NIC and income tax rates from the tax tables provided. Do not rely on memory, and do not invent rates.
  • In owner-manager questions, always bring in corporation tax and the deduction for salary and employer NIC. This is the main trap.
  • Add one or two sentences of advice beyond the figures: employment status risk, pension contributions, the £500 dividend nil rate band, cash flow. These earn professional skills marks.
  • State your assumptions, for example whether the employment allowance of £10,500 is available.

NIC Planning: Employed vs Self-Employed and Remuneration: frequently asked questions

Is self-employment always cheaper than employment for NIC?

On NIC alone, usually yes. Self-employment has only Class 4, with no employer NIC. But status depends on the facts of the working relationship, not on choice. Artificial arrangements risk HMRC challenge.

Do dividends attract national insurance?

No. Dividends carry no NIC for the company or the shareholder. They are paid from profits that have already borne corporation tax and are taxed at dividend rates of 8.75%, 33.75% or 39.35% after the £500 nil rate band.

What NIC applies to benefits in kind compared with cash salary?

Benefits carry employer Class 1A at 15% and no employee NIC. Cash salary carries employer Class 1 at 15% above £5,000 and employee Class 1 at 8% or 2%. Benefits can save NIC, but the employee is still taxed on the benefit's value.

How do I minimise NIC for an owner-managed company?

Compare salary, bonus, dividends, pension contributions and tax-free benefits on the same profit base. Check the effect of corporation tax, employer NIC and the employee's tax band. Then recommend the mix that gives the highest net cash while being genuine and compliant.
