What is Payroll in a Limited Company?

Before diving into how payroll works in a limited company, it is important to understand what payroll actually means. Payroll is the process of paying employees for the work they have completed. Payroll must comply with UK tax and employment laws, making it a legal requirement for all employers. Payroll serves four key purposes:

• Calculating employee wages and ensuring they are paid correctly.
• Calculating the amount to pay HMRC for income tax and National Insurance.
• Calculating what to pay to other organisations, such as pension funds.
• Reporting to HMRC

How Payroll Works in a Limited Company

All limited company owners need to understand the payroll process, as it ensures that employees are paid accurately and all legal obligations are met on time. Additionally, it helps businesses maintain precise financial records and remain compliant with tax regulations.

To fully grasp how payroll works in a limited company, it is important to break down the process into steps. These steps show how employee payments are calculated, reported, and processed each month.

• Collect Employee Information

Your business is required to collect and maintain accurate and up-to-date employee information. It includes employment contracts, payment details, and tax codes.

For instance, when a new team member joins a retail shop, the HR manager obtains their P45 form to find the correct tax code. Moreover, they record their bank details to ensure their salary is paid accurately.

• Record Hours Worked

The number of hours worked, the amount of overtime completed, and any absences from work must be recorded when processing the pay of employees.

For instance, a consulting firm uses a digital timesheet system to document the start and end of employees’ shifts. As a result, employees are paid accurately for the number of hours they work.

• Calculate Gross Pay

To calculate gross pay, multiply an employee’s pay rate by the number of hours worked in a specific pay period. It includes overtime, holiday pay, incentives, and commissions.

• Calculate Payroll Taxes

An employee’s tax payments depend on their National Insurance category letter and tax code. To ensure that you are on the correct path when performing manual payroll calculations, you can use HMRC’s tax tables and calculators. Additionally, you can use them to check tax, NICs and student loan deductions.

• Calculate Employee Deductions

When learning how payroll works in a limited company, calculating employee deductions is a critical step in ensuring compliant payroll processing. Determine whether any additional payroll deductions should be considered, such as pension contributions. To ensure that payments are made accurately, it is essential to understand the difference between pre-tax and post-tax deductions. Moreover, you can apply them at the correct stage of the payroll process.

• Calculate Net Pay

After calculating taxes and deductions, subtract them from the total pay. The net pay, or the take-home pay of the employee, is the actual amount that your employees will receive for the period.

• Approve Payroll

The payroll manager or the director of HR is typically responsible for approving the payroll. However, they must conduct a thorough evaluation before starting the payroll processing to ensure that employees are paid accurately.

• Pay Employees

Your business has the flexibility to choose the most convenient method for paying your employees, whether through bank transfer, BACS, online payment, cheque, or approved cash payments.

Regardless of the payment method, your company is required to provide its employees with a record of their payment. It can be either in hard copy or electronically, by the agreed-upon pay date.

• Report PAYE and NICs to HMRC in real time

On or before payday, submit payroll data to HMRC using Real-Time Information (RTI).  This comprises information regarding employees’ salaries, deductions, and PAYE and NICs. Employers are required to pay the tax and National Insurance (NI) deducted from employees via PAYE, as well as employer NICs, to HMRC.

These payments are due by the 22nd of the subsequent month (19th if paying by post). Deductions from the previous tax month (6th to 5th) are included in the payments, as indicated by the Full Payment Submission (FPS).

How Does the Payroll System Work?

Many business owners wonder how it works, and the solution lies in understanding how payroll works in a limited company. Here’s what you should do while running payroll:

Calculate Gross Pay

Before any deductions are made, the gross pay is the total amount that your employees earn. Their base salary, bonuses, overtime, and any other income or allowances are all included in this.

Deduct Income Tax

Based on the employee’s earnings and tax code, income tax is calculated. In the UK, different tax bands apply depending on annual income:

• Personal allowance: The first £12,570 is tax-free.
• Basic rate: A 20% tax rate applies to income between £12,571 and £50,270.
• Higher rate: Income between £50,271 and £125,140 is subject to a 40% tax rate.
• Additional tax rate: Income over £125,140 is taxed at 45%.

Calculate the amount of tax to deduct using your employee’s tax code.

Deduct National Insurance Contributions (NICs)

Class 1 National Insurance Contributions (NICs) are mandated payments made by employees and employers based on their earnings. Employee NICs (primary) are deducted directly from salaries above the threshold through PAYE. However, employer NICs (secondary) are paid by the employer, often at a 15% rate (from April 2025) on earnings.

Additional Deductions

Other deductions from your employee’s salary may be necessary in addition to income tax and NICs, such as:

Pension Contributions:

An employment pension scheme is mandatory for all employers. This is known as “Automatic enrolment”

If the following conditions are met, employers are required to automatically enrol eligible employees in a pension scheme and make contributions on their behalf:

• If you are between the ages of 22 and the State Pension age,
• You are classified as a “worker.”
• You must earn a minimum of £10,000 annually.
• You typically (‘ordinarily’) work in the United Kingdom

Student Loan Repayments

Employers are required to deduct student loan repayments from salaries when they exceed specific thresholds, starting with the next available payday after notification.

Net Pay

The net pay is the amount paid to the employee after all deductions, including income tax, NICs, and other deductions.

What Are The 4 Types Of Payroll Systems?

Understanding the four types of payroll systems is important when dealing with how payroll works in a limited company.

Manual Payroll Processing System

The process of manual payroll processing entails the manual calculation of salaries and taxes or the use of paper-based ledgers. This system of payroll processing is traditional and requires expertise to manage accounts.

Internal Automated Payroll Systems

To calculate earnings and deductions, automated systems rely on software utilised on local computers. Automated systems allow teams to input data once and compile reports with a single click. Internal automation reduces the amount of time spent on repetitive tasks.

Outsourced Payroll Service Providers

An external firm is involved to manage the distribution of salaries and the submission of taxes through outsourcing. Professional agencies are responsible for adhering to government regulations and mandates. This enables the management team to concentrate on its primary responsibilities.

Cloud-Based Payroll Software Systems

Cloud-based systems are accessible via the internet from any computer or device and are hosted on servers that are not located in-house. This is the most recent payroll system that offers adaptability to companies with multiple locations or remote locations. Employees can access their payslips and modify their bank details by logging into their individual portals.
