Do I need to register for PAYE?
You may need to register for PAYE if you employ staff, pay yourself a director’s salary, provide expenses or benefits, or need to report wages and deductions to HMRC.
GOV.UK’s PAYE for employers guide explains that employers normally have to operate PAYE as part of payroll to collect Income Tax and National Insurance from employment. It also says registration may be required if an employee is paid £96 or more a week, gets expenses or benefits, has another job, receives a pension, or has received certain taxable benefits.
The important point is that PAYE is not only for large employers. It can apply to a small limited company, a sole trader taking on one employee, or a company director paying themselves a salary.
Merranti’s guide to PAYE and director salaries in 2025/26 is a useful starting point for directors, while Merranti’s director remuneration guide explains how salary, dividends, National Insurance and Corporation Tax interact.
What is PAYE?
PAYE stands for Pay As You Earn. It is the system HMRC uses to collect Income Tax and National Insurance from employment income.
When you run payroll, you normally calculate:
- gross pay
- Income Tax deductions
- employee National Insurance
- employer National Insurance
- pension contributions
- student loan deductions where relevant
- net pay
- amounts due to HMRC
GOV.UK’s running payroll guide explains that employers use payroll software to record pay, calculate deductions, produce payslips, report pay to HMRC and work out what is owed.
Merranti’s how to pay yourself from your business article is useful here because sole traders and company directors are paid differently. A sole trader takes drawings, while a company director may need payroll, dividends or both.
When must you register as an employer?
You normally need to register as an employer with HMRC when you start employing staff or using subcontractors for construction work. GOV.UK’s register as an employer guidance says you must register before the first payday and cannot register more than two months before you start paying people.
You may need to register if you:
- take on your first employee
- pay yourself as a limited company director
- pay someone above the PAYE registration threshold
- provide expenses or benefits
- employ someone with another job
- employ someone receiving a pension
- need to operate Construction Industry Scheme payroll
If you are setting up a business and are unsure which registrations apply, Merranti’s guide on registering a new business with HMRC explains the difference between Self Assessment, Corporation Tax, VAT, PAYE and other registrations.
Do directors need PAYE?
Many limited company directors do need a PAYE scheme, even where there are no other employees.
GOV.UK’s register as an employer guidance says you must register even if you are only employing yourself, for example as the only director of a limited company.
This matters because a director’s salary is employment income. It is usually reported through payroll, even where the company is small and owner-managed.
Merranti’s director remuneration guide explains that directors can often take money from a company through salary and dividends, but each route is taxed and reported differently. Merranti’s guide to properly documenting dividends is also relevant because dividends cannot simply be treated as informal withdrawals.
PAYE, salary and Corporation Tax
A director’s salary can affect both the individual and the company.
For the individual, salary may create Income Tax and employee National Insurance. For the company, salary and employer National Insurance are normally business costs and can reduce taxable profits.
GOV.UK’s National Insurance rates and categories guidance explains the employee and employer National Insurance rates and thresholds used in payroll. Merranti’s Corporation Tax explained guide is useful because salary decisions can affect the company’s taxable profit and Corporation Tax position.
This is why director salary planning should not be based on one number copied from last year. It should be reviewed alongside company profit, dividends, Employment Allowance, pension planning and cash flow.
Merranti’s article on PAYE and director salaries covers this in more detail for owner-managed companies.
What happens after you register?
After registration, HMRC sends employer PAYE references. You then use payroll software, or a payroll provider, to report pay and deductions.
GOV.UK’s setting up payroll guidance says employers need to register with HMRC, choose payroll software, collect and keep records, tell HMRC about employees, record pay, make deductions and report to HMRC on or before the first payday.
GOV.UK’s PAYE Online for employers guidance explains that employers may also need to enrol for PAYE Online and activate the service.
Merranti’s accounting records guide is useful because payroll records form part of the wider record-keeping responsibilities for businesses.
Reporting payroll to HMRC
Payroll reporting is usually done through a Full Payment Submission, known as an FPS. This is sent to HMRC on or before each payday.
GOV.UK’s running payroll guide explains that employers must record pay, calculate deductions, produce payslips, report pay and deductions to HMRC, and pay HMRC by the relevant deadline.
If you have not paid employees in a tax month, you may need to send an Employer Payment Summary, or EPS. GOV.UK explains this in its running payroll overview.
Payroll mistakes can affect employees as well as the business. GOV.UK warns that late, missing or incorrect payroll reports can affect income-related benefits such as Universal Credit.
Payslips and employee records
If you employ staff, payroll is not only about HMRC. It is also about employee rights.
GOV.UK’s payslip guidance says employees and workers must be given a payslip on or before payday. Payslips must show gross pay, deductions, net pay and hours worked where pay varies by time worked.
You also need to collect and keep employee information. GOV.UK’s guide to telling HMRC about a new employee explains that you include new employee details on the first FPS when you pay them.
If you are unsure whether someone is an employee, worker, contractor or freelancer, you should check before running payroll. Employment status affects PAYE, workplace pensions, holiday pay, rights and tax treatment.
Paying HMRC
Once payroll reports have been submitted, HMRC uses them to calculate what the business owes.
GOV.UK’s paying HMRC payroll guidance says employers normally pay HMRC by the 22nd of the month, or the 19th if paying by post. Small employers that usually pay less than £1,500 a month may be able to pay quarterly instead of monthly.
This is a cash-flow issue. Payroll tax is not money available to the business. It is money deducted or owed through payroll and should be set aside.
Merranti’s guide to the tax risks of mixing personal and business money is relevant where owner-managed companies use the business bank account informally. Payroll, dividends, expenses and directors’ loans need to be kept separate.
Employment Allowance
Employment Allowance can reduce employer National Insurance for eligible businesses.
GOV.UK’s Employment Allowance guidance says eligible employers can reduce their annual National Insurance liability by up to £10,500. GOV.UK’s Employment Allowance eligibility guidance also says a company with only one director cannot claim if that director is the only employee liable for secondary Class 1 National Insurance.
This is one of the most common mistakes for small companies. A director-only company may assume Employment Allowance applies, when it does not.
Merranti’s Employment Allowance in 2026 guide explains why eligibility should be reviewed annually. Merranti’s Employment Allowance 2025/26 guide also covers common mistakes, including single-director companies, connected companies and payroll setup errors.
Workplace pensions
PAYE can also lead into workplace pension duties.
GOV.UK’s workplace pensions employer guidance says employers must provide a workplace pension scheme for eligible staff from the date the first member of staff starts working. Eligible staff generally include workers aged between 22 and State Pension age who earn at least £10,000 a year and usually work in the UK.
GOV.UK’s guide on how to set up a workplace pension scheme says employers must pay at least 3% of qualifying earnings into the pension scheme.
This is not optional admin to think about later. Payroll, pension assessment, employee letters and contributions need to be built into the employer process from the start.
Merranti’s director remuneration guide also touches on pension planning as part of wider company remuneration.
PAYE and benefits in kind
PAYE can also be relevant where employees or directors receive expenses and benefits.
GOV.UK’s PAYE for employers guide says you must register for PAYE if an employee gets expenses and company benefits. GOV.UK’s running payroll payments guidance explains that some expenses and benefits are reported separately at the end of the tax year.
Benefits can include company cars, private medical insurance, beneficial loans, accommodation or other non-cash benefits. These can create Income Tax and employer National Insurance issues.
Merranti’s business expense guide is useful for distinguishing business expenses, personal costs, reimbursements and benefits.
Common PAYE mistakes
The first mistake is registering too late. GOV.UK says you must register before the first payday, although you cannot register more than two months before paying people. See GOV.UK’s register as an employer guidance.
The second mistake is assuming a director-only company does not need PAYE. It may still need to register if the director is paid a salary.
The third mistake is treating dividends as salary or salary as dividends. Merranti’s dividend documentation guide explains why dividends need proper approval and retained profits.
The fourth mistake is missing Employment Allowance. Some businesses do not claim when they could. Others claim when they are not eligible. Merranti’s Employment Allowance guide explains the key checks.
The fifth mistake is ignoring pensions. Payroll and automatic enrolment are connected. GOV.UK’s workplace pensions employer guide sets out the employer duties.
Speak to Merranti before your first payday
PAYE is easier to set up correctly than to fix later. Once employees are paid, payroll reports, tax deductions, payslips, pensions and HMRC payments all need to line up.
Merranti’s PAYE and director salaries guide is a useful starting point for limited company directors, while its guides on director remuneration, Employment Allowance, Corporation Tax, business expenses and business registration with HMRC cover the main connected issues.
If you are taking on staff, setting up a limited company payroll, or paying yourself as a director, contact Merranti Accounting before the first payday so the payroll scheme, salary level, Employment Allowance position and reporting process are set up properly.
Do I need to register for PAYE if I employ someone?
Usually, yes, if the employee meets PAYE conditions. GOV.UK’s PAYE for employers guide explains when employers normally need to operate PAYE.
Do I need PAYE if I only pay myself as a director?
Yes, you may still need to register. GOV.UK’s register as an employer guidance says you must register even if you are only employing yourself, for example as the only director of a limited company.
When must I register for PAYE?
You must register before the first payday, but GOV.UK says you cannot register more than two months before you start paying people. See GOV.UK’s register as an employer guidance.
Can an accountant run payroll for me?
Yes. GOV.UK says employers can run payroll themselves or use a payroll provider, but the employer remains legally responsible for PAYE tasks. GOV.UK explains this in choose how to run payroll.
Can I claim Employment Allowance?
Possibly. GOV.UK says eligible employers can reduce their annual employer National Insurance liability by up to £10,500, but single-director-only companies usually cannot claim where the director is the only employee liable for secondary Class 1 National Insurance. See GOV.UK’s Employment Allowance eligibility guidance and Merranti’s Employment Allowance in 2026 guide.
