Director-Only Payroll: What a Single-Director Company Needs to Do

Most directors running a limited company are paying themselves wrong. Not catastrophically. Not in a way that feels urgent. Just quietly, consistently, in a way that leaves a trail HMRC can follow if they ever decide to look.

The problem is not the salary level. The problem is the administration around it.

Director-only payroll means running a PAYE scheme for a company where the sole or primary employee is a director. It sounds simple. It is, in the doing. Where it falls apart is in the filing — the monthly RTI submissions that most director-only companies either skip, batch, or hand to an accountant who treats payroll as a year-end job rather than a monthly obligation.

HMRC does not treat it as a year-end job. They treat it as monthly. Every month.

What "Director-Only Payroll" Actually Requires

When a director takes a salary — even a modest one, even the standard £12,570 personal allowance salary that most limited company directors use — the company becomes an employer. The director is simultaneously the employer and the employee. HMRC does not consider this a paradox. They consider it a standard arrangement with standard obligations.

Those obligations are:

Register for PAYE before the first payment. Not after. Not at year end. Before.

Submit a Full Payment Submission (FPS) to HMRC on or before the date of every salary payment. This is the Real Time Information requirement — RTI. It was introduced in 2013 and it is still catching director-only companies out in 2026.

If no salary is paid in a given month, submit an Employer Payment Summary (EPS) instead. The EPS tells HMRC: we're registered, we're active, we paid no salary this month. Without it, HMRC assumes the FPS is late and starts calculating penalties.

Issue payslips. A director is entitled to a payslip like any other employee, and good records mean the year-end reconciliation doesn't become a problem.

Submit an Employer Annual Return (P35 / final FPS) at the end of the tax year and issue a P60 to the director by 31 May.

The Salary Question

The majority of director-only companies pay a salary at or near the personal allowance — £12,570 in 2026/27 — and take the rest of their income as dividends.

The logic: salary up to the personal allowance attracts no income tax. At £12,570, it also sits above the Primary Threshold (£12,570) for National Insurance, meaning the director pays employee NI. At slightly below — the traditional strategy was to pay exactly at the Secondary Threshold to avoid NI altogether — the position has changed with recent NI threshold adjustments.

The optimal director salary in 2026/27 depends on individual circumstances: whether there are other income sources, whether the company has additional employees (which affects the Employment Allowance eligibility), and whether the company itself has sufficient profit to justify the salary as a business expense.

This is accountant territory, not payroll bureau territory. The payroll bureau runs the number correctly once the number is confirmed. Getting the number wrong is a different, more expensive problem.

The Part Most Directors Are Getting Wrong

Here is the part nobody talks about in the LinkedIn posts about limited company tax efficiency.

The RTI filing. Monthly. Every month.

Most director-only companies, in the experience of every payroll bureau that works with them, fall into one of three patterns:

Pattern one: The accountant handles payroll but only looks at it quarterly or at year end. The RTI submissions are either late, batched, or being done in a single catch-up submission in March that technically covers the year but technically did not meet the monthly filing requirement.

Pattern two: The director handles payroll themselves through a software package, gets it right for the first few months, then the day of the monthly payrun slips, then the payslip isn't issued, then it's three months in and there are gaps in the RTI record.

Pattern three: The director hasn't registered for PAYE at all, is taking money from the company as ad hoc drawings or director loans, and is planning to "sort it out properly" at some point. That point is usually the date the accountant mentions a year-end liability or HMRC issues a compliance query.

None of these feel catastrophic in the moment. They all feel manageable, something to sort later. The problem is that HMRC records everything and reviews it. When the company goes through due diligence for a sale or investment, the PAYE record is examined. When HMRC runs a PAYE compliance check, they go back as far as the records extend. The gaps do not disappear.

National Insurance for Directors

Director NI works differently from employee NI, and this is another area where software errors and manual errors accumulate silently.

Directors have an annual earnings period for NI purposes, not a monthly one. This means NI is calculated on the director's cumulative earnings across the tax year rather than on each monthly payment individually. The practical effect is that early salary payments in the tax year may attract little or no NI, while later payments — once the annual threshold is passed — attract the full rate.

This is not wrong. It is correct. But it is different from how NI is calculated for regular employees, and payroll software set up incorrectly — or a manual calculation treating the director like an employee — will get this wrong every time.

IR35 and the PSC Context

Director-only companies operating as personal service companies — the contractor director billing through a limited company — have an additional layer: IR35.

IR35 is HMRC's mechanism for determining whether a contractor who operates through a company is genuinely self-employed or is, in substance, an employee of the client they work for. If HMRC determines the latter, the income should have been treated as employment income and taxed accordingly.

The practical implication for payroll is about documentation. The payroll record — the salary level, the consistency of RTI filing, the proper PAYE registration — is part of the evidence base that a director is running a genuine business and taking a legitimate director salary. Gaps in RTI, ad hoc payments, no P60 — these are not proof of IR35 risk, but they are gaps that HMRC can use to make a case more complicated than it needs to be.

What Clean Director Payroll Looks Like

It is not complicated. It is consistent.

PAYE scheme registered. Salary confirmed with the accountant. RTI FPS submitted on or before the payment date every month. EPS submitted in any month where no payment is made. Payslips issued. P60 at year end by 31 May.

That is it. Twelve FPS submissions or twelve EPS submissions — whichever applies. One P60. One year-end submission.

The cost of getting this wrong is not always immediate. It is cumulative. Late filing penalties of £100 per month add up. Gaps in state pension contributions are not recovered easily. And the accountant's time correcting a year of missed RTI filings costs more than the bureau that would have done it properly costs in a month.

bookd. manages director payroll for limited companies on a fixed monthly fee — registration, monthly RTI, payslips, year-end P60. The filing happens monthly because it's supposed to happen monthly.

If your current setup involves anyone "sorting it at year end," that is not director payroll. That is the appearance of director payroll. They are not the same thing.
