Director’s National Insurance: A Full Guide for UK Company Directors

Director’s National Insurance (NI) is paid through PAYE on their salary. However, it works differently from an ordinary employee’s NI, both in how contributions are calculated and when they are due.

Getting the calculation right matters because the amount you pay can affect both your take-home pay and your company’s payroll costs.

Here’s what you need to know for 2026/27.

Key points

• Salary and dividends are treated differently 💰
  Salary can trigger employee and employer NI, while dividends don’t. This is why many director-shareholders use a combination of salary and dividends.
• Employer NI is a company cost 🏢
  Your company pays employer NI on salary above the Secondary Threshold. It’s a deductible business expense, which can reduce your Corporation Tax bill. Some companies may also qualify for the Employment Allowance.
• Your salary can affect your State Pension record 🏦
  Earnings between the Lower Earnings Limit and Primary Threshold can still count towards a qualifying year, even though you don’t pay employee NI on them.
• ANNA’s payroll can take the calculation off your hands 🚀
  You shouldn’t need three tools and a spreadsheet to pay yourself. ANNA brings your payroll, bookkeeping, and wider business admin together into one account, and handles most of the work for you.

How does National Insurance work for company directors?

For NI purposes, a company director is treated as an employee.

That means if your limited company pays you a salary, the company needs to run payroll, deduct any Income Tax and employee NI due, and then pay you.

There are two different NI contributions:

• Employee NI, which is deducted from your salary and reduces your take-home pay
• Employer NI, which is paid by your company on top of your gross salary and doesn’t come out of your take-home pay

Dividends work differently. Since they aren’t earnings from employment, they don’t attract employee or employer NI.

However, they can be subject to dividend tax, and they can only be paid from available company profits after Corporation Tax.

National Insurance rates and thresholds for 2026/27

Four earnings points decide what NI you and your company pay, and whether the year counts towards your State Pension. Check out the figures that apply for the 2026/27 tax year, running from 6 April 2026 to 5 April 2027:

For employee NI, the rates are:

• 0% on earnings up to £12,570
• 8% on earnings between £12,570 and £50,270
• 2% on earnings above £50,270

For employer NI, the rate is 15% on earnings above the £5,000 Secondary Threshold.

The Personal Allowance has been frozen at £12,570 since 2021/22, and the Primary Threshold has matched it since July 2022. The freeze now runs to 2030/31.

Why the director’s National Insurance is different

HMRC treats directors differently from typical employees because they have more control over their pay. An employee’s NI is usually calculated fresh each pay period, but the director’s isn’t.

If you’re a director, you’re given an annual earnings period, which means your NI is based on your cumulative earnings across the whole tax year, from 6 April to the following 5 April.

If directors were assessed like everyone else, they could take their entire year’s salary as a single lump sum in one week and pay far less NI than someone earning the same amount spread evenly across twelve months.

Only a small slice of that lump sum would fall above the weekly Upper Earnings Limit, so most of it would be taxed at the lower 2% rate instead of 8%. The annual earnings period closes that gap and makes sure directors pay roughly as much NI as anyone else earning the same amount over a year.

How is a director’s NI calculated?

You can calculate a director’s NI using two methods: the annual method and the alternative method.

The method you use affects when NI is deducted during the year, although the annual calculation ultimately determines the director’s position.

The annual method

Under the annual method, your NI is calculated using your cumulative earnings for the tax year.

For example, suppose you receive £3,000 each month from April to August. Your cumulative salary reaches £15,000 in August.

Because employee NI starts once your earnings exceed the £12,570 Primary Threshold, your August payroll calculation will result in an NI deduction. Payroll tracks your running total, not each payslip separately.

The annual method is commonly used for directors who receive a regular salary because it gives a running calculation of their NI position.

The alternative method

The alternative method calculates NI throughout the year using the normal weekly or monthly thresholds, similar to how NI is calculated for regular employees.

At the end of the tax year, payroll checks the total NI you have paid against what you should have paid based on your total annual earnings. If there is a difference, it’s corrected in the final pay period.

This can be useful when your salary is irregular because your NI deductions follow each payment more closely.

What if you pay yourself a bonus or irregular salary?

Directors often don’t receive the same amount every month.

You might pay yourself a basic salary and then make an additional payment, such as a bonus, when the company has enough cash available.

Timing can affect when NI appears on your payslips, particularly under the annual method.

Suppose you have earned £8,000 during the first part of the tax year and then receive a £10,000 bonus.

Your cumulative earnings suddenly become £18,000.

The payroll calculation will take your total earnings so far into account, rather than treating the £10,000 payment as separate from everything you have already earned. This can result in a noticeable NI deduction from the bonus payment.

The same principle applies in reverse. If your pay varies during the year, the amount of NI deducted on each payslip doesn’t necessarily tell you what your final annual NI position will be.

Employer National Insurance and the Employment Allowance

Your company pays its own NI on top of your salary, at 15% on everything above £5,000 a year. This comes out of company funds, not your take-home pay.

Many small companies can offset some or all of this through the Employment Allowance, which is worth up to £10,500 for 2026/27.

Employer NI counts as a business expense, so it lowers your company’s taxable profit and reduces your Corporation Tax bill.

Your gross salary is deductible too. So a pound paid as salary costs your company less than a pound paid as a dividend, which comes out of profit after Corporation Tax. That’s why many directors pay a salary above the Secondary Threshold, especially where the Employment Allowance covers the employer NI.

Your accountant can model this alongside your specific profit figures, since the saving depends on your company’s Corporation Tax rate and your proximity to the profit bands.

💡 Did you know?

Keeping track of salary, dividends, and company expenses in one place makes it much easier to see your real NI and tax position as the year goes on.

ANNA’s business account brings your transactions, invoicing, and bookkeeping together so nothing gets missed when it’s time to run payroll or file your accounts.

Salary and dividends: Getting the balance right

Because dividends aren’t earnings, you don’t pay employee NI on them, and your company doesn’t pay employer NI either. This is why most director-shareholders take a modest salary and top it up with dividends rather than taking everything as pay.

Did you know?

A salary set around the Primary Threshold of £12,570 is a common starting point, since it uses up your tax-free Personal Allowance without triggering any employee NI.

Whether it makes sense to go slightly higher, up to the Secondary Threshold or beyond, depends on factors like:

• Whether you can claim the Employment Allowance
• Whether building qualifying years for your State Pension matters to you right now
• What your company’s profits look like once dividend tax is factored in

Dividend tax rates changed again in April 2026, narrowing the gap between salary and dividends for some directors compared with previous years. The right split depends on your specific numbers, so it’s often a good idea to run the figures with an accountant.

National Insurance and your State Pension

Your NI record also builds your entitlement to the State Pension and other contributory benefits later. You need 35 qualifying years for the full new State Pension, and at least 10 qualifying years to get anything at all.

If your salary sits between the Lower Earnings Limit and the Primary Threshold, you’re treated as having paid NI for State Pension purposes even though nothing is deducted. Pay yourself below the Lower Earnings Limit though, and that year won’t count unless you top it up separately.

Running more than one company

If you’re a director of two or more companies, each one is treated as a separate employer for NI purposes, but only up to a point.

Where the companies are independent of each other, with different ownership and no shared control, each pays you separately and calculates its own employer and employee NI as though the other didn’t exist.

This can mean you pay less NI overall than someone earning the same total from one job, because each employment gets its own set of thresholds.

Where the companies are connected, for example one is a subsidiary of the other, or the same person or group controls both, HMRC treats them as associated employers for NI purposes. In that case, you have to add the earnings from both roles and calculate NI on the combined total, using a single set of annual thresholds.
