Director Payroll Guide

From April 2025, the employer NIC rate moved to 15% and the Secondary Threshold dropped to £5,000. That shift changed the optimal director salary calculation.

If you last reviewed your structure before April 2025, the numbers you are using are now wrong.

Director payroll also has one mechanical rule that surprises most people: your National Insurance is calculated on an annual earnings period, not monthly. That changes how you can structure director pay in ways an employee cannot use.

Payroll software configured for employees produces incorrect NIC calculations for directors unless you explicitly enable the director method.

This guide covers the current thresholds, the annual NIC mechanic, and the IR35 interaction that can undo a well-structured split.

Why does director salary optimisation work differently from employee pay?

Employees pay National Insurance on each payslip in isolation. If you earn £3,000 in one month, NIC is calculated on that month’s earnings against the monthly Primary Threshold (£1,047.50 for 2025/26).

The next month resets.

Under HMRC’s CWG2, a director’s NIC liability accumulates across the whole tax year. Each payment is assessed against cumulative earnings since 6 April.

Employee NIC only starts when cumulative earnings cross the annual Primary Threshold (£12,570).

The practical consequence: a director paid nothing from April to February, then paid £12,000 in March, owes zero employee NIC. Cumulative earnings never crossed £12,570.

An employee paid the same amount in March would pay NIC on the excess above the monthly threshold.

Most payroll software defaults to the employee method.

If yours is not explicitly set to director (annual earnings period), it over-collects NIC on irregular payments and the year-end reconciliation creates confusion on both sides.

What is the optimal director salary level in 2025/26?

Before April 2025, paying salary at the personal allowance (£12,570) was common. It avoided income tax and sat above the employer NIC Secondary Threshold. That calculation changed.

The employer NIC rate rose from 13.8% to 15% and the Secondary Threshold dropped from £9,100 to £5,000. On a director salary of £12,570, your company now pays 15% on £7,570: £1,135.50 in employer NIC per year, up from approximately £470 in 2024/25.

A 140% increase on the same salary.

The LEL strategy sidesteps this. At £6,396 (the 2025/26 LEL) you pay zero employee NIC and zero employer NIC, and you still get a qualifying State Pension year. Your company saves £1,135-plus compared with the personal-allowance salary.

The shortfall comes via dividends instead.

The right choice depends on your profit level and pension contribution priorities. Single-director companies cannot claim Employment Allowance, so there is no offset on the employer NIC above £5,000.

An accountant can model this in one meeting.

How does the dividend allowance cut affect your director salary-dividend split?

Your 2025/26 dividend allowance is £500. Anything above that is taxable at your marginal dividend rate: 8.75% at basic rate, 33.75% at higher rate.

On £30,000 of dividends above your allowance, you owe £2,625 in dividend tax.

That is still substantially cheaper than taking the same amount as salary, where employee NIC (8%), employer NIC (15% above £5,000), and income tax (20%) would all apply.

The practical shift is in admin. With £500, almost every substantive dividend creates a Self Assessment liability.

In a multi-director company, each shareholder has their own £500 allowance, but dividend payments must be proportionate to share class unless your articles permit alphabet shares.

One constraint people miss: dividends can only be paid from distributable reserves. If your company has accumulated losses, you may not legally declare a dividend even if cash is available.

This is a Companies Act requirement, not a technicality.

What does IR35 mean for your director payroll structure?

If your company provides services to a medium or large private-sector client, that client assesses whether your engagement falls inside IR35 under the off-payroll working rules (in force since April 2021).

An inside-IR35 determination triggers a deemed payment calculation. The contract income is treated as employment income, with NIC and PAYE deducted before payment reaches your company. Employer NIC comes off at 15%.

On £80,000 of annual contract income, that is £10,125 before you have paid yourself anything.

The interaction with director payroll is what clients most often underestimate. The deemed payment applies to gross contract income regardless of what director salary you are already drawing.

If your work is inside IR35 and you are running the LEL-salary-plus-dividends structure, NIC cost hits twice: once via the deemed payment on contract income, again on dividends from a profit pool already reduced by that NIC.

An accountant with contractor-structure experience can model whether drawing more salary improves your overall position via pension eligibility.

What software and process do you need to run director payroll correctly?

You need payroll software that supports the HMRC director NIC method. Xero, Sage Payroll, BrightPay, and Moneysoft all support this.

You must explicitly designate the employee record as a director and confirm the annual earnings period method is active. If you promoted an existing employee to director, verify the record was updated.

The default employee method creates an NIC underpayment that surfaces at year-end reconciliation.

RTI submissions are required even if no PAYE or NIC is due. You need a Full Payment Submission for each pay event, and an Employer Payment Summary when no payment is made in a period.

Missing RTI on a director-only payroll triggers automatic late-filing penalties.

If your accountant has not mentioned the annual NIC method and you pay yourself irregularly, ask them to confirm which method your record uses before your next pay run.
