What running payroll involves
Payroll is more than working out a payslip. Every time you pay an employee you have to calculate income tax under PAYE, employee and employer National Insurance, student loan deductions and pension contributions. You then report those figures to HMRC in real time, on or before payday, through a Full Payment Submission.
On top of that there are statutory payments such as sick pay, maternity and paternity pay, starter forms for new staff, P45s for leavers and P60s at the end of the year. For a restaurant on North End Road with shifting hours, or a dental practice in Parsons Green with part time nurses, the details change every month. We handle it all and send you a simple report showing what to pay staff and what to pay HMRC.

Employer National Insurance and the Employment Allowance
Employer National Insurance is charged at 15% on earnings above the secondary threshold. This is a cost to the business on top of wages, and it has become a bigger factor in hiring decisions since the rate went up.
Many employers can claim the Employment Allowance, which reduces the employer National Insurance bill by up to £10,500 a year. It is not given automatically. You have to claim it through payroll software. Companies where the only employee paid above the threshold is a director cannot claim it, which matters for many one person companies. We check eligibility and make the claim at the start of each tax year.
Workplace pensions and auto enrolment
Every employer must put eligible staff into a workplace pension and pay into it. Eligible staff are workers aged from 22 up to State Pension age who earn above the earnings trigger. Others can ask to join, and in some cases you must contribute for them too.
The minimum total contribution is 8% of qualifying earnings, with at least 3% coming from the employer. Within five months of your duties starting you must complete a declaration of compliance with The Pensions Regulator. Then, roughly every three years, you must put staff who opted out back into the scheme and redeclare. We set up the scheme with your chosen provider, assess every employee each pay period, send the right letters and upload contributions.
Directors, benefits and year end
Director payroll has its own rules. National Insurance for directors is normally worked out on an annual basis rather than pay period by pay period, so a director who takes a large bonus in one month does not pay less than an employee on the same yearly salary. Many payroll packages get this wrong unless they are set up properly.
If you give staff benefits such as private medical insurance, a company car or gym membership, these are usually taxable. You can report them on P11D forms after the year end, or tax them through payroll as you go. The government has confirmed that payrolling of benefits will become compulsory, phased in from 6/4/2027, so it is worth getting used to it now. Employers in Fulham and Chelsea offering health cover to staff are often affected.
Mistakes small employers make
The Pensions Regulator and HMRC both issue fines, and some of the most common problems are easy to avoid.
- Paying staff before registering as an employer with HMRC
- Forgetting to assess a new starter or a worker whose pay has risen for auto enrolment
- Missing the redeclaration every three years
- Calculating director National Insurance as if they were a normal monthly employee
- Paying below the National Minimum Wage once unpaid time or deductions are taken into account
Setting up payroll with us
To get started we need your PAYE reference and Accounts Office reference from HMRC, details of each employee including their starter information or P45, their pay rates and hours, and your pension provider details if you already have one. If you are switching from another provider, we also need payroll records for the year so far.
Each month you tell us about new starters, leavers, overtime or sick days. We run the payroll, send payslips to staff, file with HMRC and give you a summary of what to pay and when. Employers in Fulham, Hammersmith and Shepherds Bush can send updates by email or through shared software. Send us an enquiry with your number of employees and pay frequency, and we will agree a fixed fee before any work starts.
Who this suits
- Company directors paying themselves a salary
- Restaurants, cafes and shops with part time and shift staff
- Dental and medical practices in Fulham and Chelsea
- Small employers taking on their first member of staff
- Businesses unhappy with their current payroll provider
Common questions
Do I need to run payroll if I am the only director?
If you pay yourself a salary through the company, yes. Many directors take a modest salary and register as an employer so it can be reported to HMRC. Even if no tax is due on the salary, the reporting still has to happen.
When do I have to pay PAYE to HMRC?
By the 22nd of the month after the payroll month if you pay electronically. Small employers with low monthly bills may be able to pay quarterly instead.
Who has to be auto enrolled into a pension?
Workers aged from 22 up to State Pension age who earn above the earnings trigger and normally work in the UK. Other staff have the right to opt in or join, and you may need to contribute for some of them.
How much do I have to pay into staff pensions?
The legal minimum is 8% of qualifying earnings in total, of which the employer must pay at least 3%. You can choose to pay more.
Can I claim the Employment Allowance?
Most employers can, which cuts their employer National Insurance bill by up to £10,500 a year. You cannot claim it if a director is the only employee paid above the secondary threshold.
What happens if I file payroll late?
HMRC can issue penalties for late Full Payment Submissions, based on how many employees you have, and charges interest on late payments. The Pensions Regulator can also fine you for auto enrolment failures.
Can you take over payroll partway through the tax year?
Yes. We bring across the year to date figures from your previous provider so the totals are correct, and you will not notice a gap in reporting.
