What Is PAYE? A Complete Guide for UK Employers
For most employees in the UK, PAYE is something that happens quietly in the background. Income Tax and National Insurance are calculated through payroll, deducted where required, and reflected in each payslip.
For employers, PAYE is an ongoing responsibility. It involves setting up payroll correctly, maintaining employee information, calculating deductions, reporting payroll information to HMRC through Real Time Information, or RTI, and paying HMRC what is due.
The process is repetitive, but that does not mean it has to be manual. Once the payroll workflow is set up, the same core steps repeat every pay period. HMRC-compliant payroll software such as Zoho Payroll can help automate calculations, organise payroll records and support RTI reporting, reducing the administrative work involved in running PAYE.
This guide explains what PAYE is, how it works, what employers need to do at each stage, and how Zoho Payroll can simplify the process.
What is PAYE?
PAYE stands for Pay As You Earn. It is HMRC's system for collecting Income Tax and National Insurance from employment income as employees are paid.
Instead of employees paying all their tax in one amount at the end of the tax year, employers calculate and deduct the relevant amounts through payroll and report that information to HMRC. PAYE is therefore not a tax in itself. It is the system used to calculate, collect and report employment-related tax and National Insurance.
For employers, operating PAYE typically involves:
maintaining accurate employee payroll information
using the relevant tax code and National Insurance details
calculating gross pay and statutory deductions
processing other deductions where applicable, such as Student Loan repayments
sending payroll information to HMRC through RTI
paying HMRC what is due by the relevant deadline
keeping payroll records
As a business grows, these tasks can become increasingly time-consuming to manage manually. Zoho Payroll brings payroll calculations, employee records and reporting into one workflow, helping employers spend less time moving information between systems.
Who needs to register for PAYE?
Before you can operate PAYE, you may need to register as an employer with HMRC. You generally need to register before your first payday if you employ someone who meets HMRC's criteria for PAYE registration, including situations where they earn above the relevant threshold, have another job or pension, or receive taxable benefits.
Once registered, HMRC provides the references you need to operate and report PAYE, including your Employer PAYE Reference and Accounts Office Reference.
It is important to register before payroll begins. Your employer details are required when setting up your payroll software and sending RTI submissions.
How Zoho Payroll helps with setup
Zoho Payroll allows employers to keep employer payroll details and employee information within the same system used for ongoing payroll processing. This helps create a consistent record from setup through each pay run.
How does PAYE work?
Although PAYE involves several moving parts, the process follows the same basic sequence every time employees are paid.
1. Collect employee information
Before processing payroll for a new employee, you need the information required to set up their PAYE record. Depending on the employee's circumstances, this can include a P45 or starter information, a National Insurance number, tax code, salary details and pension information.
Accurate information matters because payroll calculations depend on the employee's tax and payroll details.
With Zoho Payroll
Employee payroll profiles can store the information used during payroll processing, helping employers maintain employee records in one place and reduce repetitive data entry.
2. Calculate payroll and PAYE deductions
Each pay run starts with gross pay. Payroll then calculates the relevant deductions and contributions based on the employee's circumstances and current rules.
This can include:
Income Tax
employee National Insurance
employer National Insurance
Student Loan or Postgraduate Loan repayments where applicable
pension contributions
other statutory or authorised deductions
With Zoho Payroll
Zoho Payroll helps automate payroll calculations using employee payroll information and applicable rules. Employers can review the calculated figures before finalising payroll, reducing the need to manually work through every deduction.
3. Send payroll information to HMRC
Employers running PAYE generally report payroll information to HMRC through RTI. The main report is the Full Payment Submission, or FPS.
The FPS tells HMRC who has been paid, how much they were paid and the deductions and contributions recorded through payroll. It is normally sent on or before payday.
With Zoho Payroll
As an HMRC-compliant payroll solution, Zoho Payroll supports the PAYE reporting workflow alongside payroll processing. This keeps payroll data and RTI reporting connected, helping employers avoid recreating the same information in separate systems.
4. Send an EPS where required
Some situations require an Employer Payment Summary, or EPS. For example, employers may need to send an EPS to report that no employees were paid in a tax month, reclaim certain statutory payments, claim Employment Allowance or report other adjustments that affect the amount owed to HMRC.
The EPS is generally sent by the 19th of the following tax month when required for HMRC to apply relevant adjustments.
With Zoho Payroll
By keeping payroll and statutory reporting connected, Zoho Payroll helps employers manage the information needed for PAYE reporting without treating each submission as a completely separate administrative exercise.
What comes out of pay under PAYE?
PAYE is often associated with Income Tax, but payroll can include several deductions and employer contributions depending on the employee's circumstances.
Deduction or contribution | Who pays it? | What it means |
Income Tax | Employee | Tax deducted from taxable employment income where applicable |
Employee National Insurance | Employee | National Insurance contribution calculated through payroll |
Employer National Insurance | Employer | Employer contribution paid in addition to salary |
Student Loan repayments | Employee | Repayments deducted where the employee and earnings meet the relevant criteria |
Postgraduate Loan repayments | Employee | Additional loan repayments where applicable |
Not every employee will have every deduction. The payroll calculation depends on their individual tax code, earnings and other relevant information.
How Zoho Payroll helps
A growing team can mean dozens or hundreds of different payroll calculations in a single pay run. Zoho Payroll helps apply the relevant calculations consistently based on each employee's payroll information, reducing the administrative burden of manual calculations.
How is PAYE calculated?
PAYE is not a single fixed percentage applied to every employee. Payroll calculations can depend on several factors, including:
the employee's tax code
gross earnings
pay frequency
applicable Income Tax rates and bands
National Insurance thresholds
cumulative earnings and tax information where applicable
For many employees, PAYE is cumulative. That means the calculation can take into account what has happened earlier in the tax year rather than looking only at the current payslip.
How Zoho Payroll helps
Zoho Payroll automates payroll calculations using the employee and payroll information held in the system. This reduces the need to manually calculate tax and statutory deductions for each employee while still allowing employers to review payroll before approval.
Understanding PAYE tax codes
An employee's tax code helps determine how much Income Tax should be deducted through payroll. The code reflects the employee's tax circumstances and may change when HMRC updates its records.
Example | General meaning |
1257L | A common standard tax code for employees receiving the standard Personal Allowance |
BR | Basic-rate tax applied to relevant earnings, often used in situations such as a second job |
0T | No Personal Allowance applied |
K | Taxable benefits or other adjustments can result in taxable income exceeding available allowances |
S-prefix codes | Scottish Income Tax rates may apply |
Using the wrong tax code can result in incorrect deductions and may create additional correction work later.
How Zoho Payroll helps
Employee tax codes can be maintained as part of the payroll record and used during payroll calculations. When employee information changes, employers can update the record and process future payroll using the revised details.
What is emergency tax?
Employees may sometimes be placed on a temporary or non-cumulative tax basis when HMRC does not yet have enough information to apply the correct cumulative tax code. This can happen when someone starts a new job without complete starter information.
Codes with W1, M1 or X indicators are commonly associated with a week 1 or month 1 basis. Once the correct information is available, the tax code may be updated and future payroll calculations adjusted accordingly.
The employer's PAYE cycle
PAYE becomes a recurring payroll process once your scheme is set up. The exact requirements can vary by employer and circumstances, but the core workflow looks like this:
Employer responsibility | When it happens | How Zoho Payroll helps |
Set up PAYE and payroll details | Before payroll begins | Keep employer and payroll information organised in one system |
Maintain employee information | When employees join and when details change | Store payroll profiles and relevant tax information |
Process payroll | Every payday | Automate payroll calculations and deductions |
Send FPS | Normally on or before payday | Support the connected payroll and RTI reporting workflow |
Send EPS where required | By the relevant HMRC deadline | Keep payroll information organised for statutory reporting |
Review PAYE liability | After payroll and reporting | Use payroll records and reports to understand what is due |
Pay HMRC | By the relevant payment deadline | Use payroll information to review liabilities before payment |
Complete year-end tasks | At the end of the tax year | Maintain payroll records and statutory documentation |
The important point is that payroll software can automate calculations and reporting tasks, but the employer remains responsible for the accuracy of payroll and for meeting HMRC obligations.
What automated PAYE actually means
Automating PAYE does not mean handing over responsibility for payroll. Employers still need to maintain accurate information, review payroll and ensure HMRC receives what is due on time.
Automation changes the amount of repetitive work involved. Instead of manually checking calculations, recreating payroll information for reports and maintaining disconnected records, employers can manage these activities through a connected payroll workflow.
With Zoho Payroll, employers can bring together:
PAYE and National Insurance calculations
employee tax and payroll information
statutory deductions
payroll processing
RTI reporting workflows
payslips and payroll documentation
payroll records and reporting
The employer remains in control, but the process requires less manual administration.
Why businesses move away from manual PAYE
Manual payroll can be manageable for a very small workforce with straightforward pay. As the team grows, however, payroll becomes more complex.
Employees may have different tax codes, deductions, salaries, bonuses, pension arrangements or loan repayments. A change to one employee's details can affect future payroll calculations. Businesses also need to keep up with recurring reporting and payment deadlines.
This is where an HMRC-compliant payroll system can make a meaningful difference. Zoho Payroll connects calculations, payroll records and reporting so employers do not have to treat each activity as a separate task.
A typical workflow becomes:
review employee information and payroll inputs
process payroll
review calculated deductions and contributions
finalise the pay run
complete the required reporting workflow
review what is due to HMRC
Common PAYE mistakes employers can avoid
Using incorrect or outdated employee information
Missing starter information or an incorrect tax code can affect payroll calculations. Keeping employee payroll details organised makes it easier to identify and update changes.
Missing an RTI deadline
The FPS is normally due on or before payday, and some EPS submissions have their own deadlines. A connected payroll and reporting workflow can help prevent reporting from becoming a separate task that is forgotten after employees have been paid.
Making manual calculation errors
Different employees can have different deductions and tax circumstances. Automating calculations reduces the amount of repetitive arithmetic and helps employers process payroll more consistently.
Forgetting to review PAYE liabilities
The amount paid to employees is not the full cost of payroll. Employers also need to understand the Income Tax and National Insurance amounts due to HMRC. Regular payroll reports provide visibility before the payment deadline arrives.
Using disconnected systems
Managing calculations in spreadsheets, employee records elsewhere and reporting through separate processes can create duplicate work. Bringing these activities together in Zoho Payroll can create a more consistent workflow and reduce repeated data entry.
What stays with the employer?
Payroll software can automate parts of PAYE, but accountability does not disappear. Employers remain responsible for:
registering and operating PAYE where required
maintaining accurate employee information
reviewing payroll
meeting RTI reporting requirements
paying HMRC on time
keeping the required payroll records
This is why payroll automation works best as a support system. Zoho Payroll can handle repetitive calculations and connected reporting tasks while employers retain oversight of payroll decisions and obligations.
Simplify PAYE with Zoho Payroll
PAYE is not a one-time task. It repeats every time you pay employees.
The responsibilities remain familiar:
Calculate the right deductions
Report payroll information correctly
Keep accurate records
Pay HMRC what is due on time
The difference is how much manual work it takes to complete those steps.
Zoho Payroll provides an HMRC-compliant way to manage payroll and PAYE in a connected workflow. By bringing payroll calculations, employee records and statutory reporting together, it helps employers spend less time on repetitive administration and more time reviewing the payroll process with confidence.

Frequently asked questions about PAYE
What does PAYE stand for?
PAYE stands for Pay As You Earn. It is HMRC's system for collecting Income Tax and National Insurance through payroll as employees are paid.
2. Is PAYE the same as Income Tax?
No. PAYE is the system used to calculate, collect and report employment-related deductions. Income Tax is one of the deductions that can be processed through PAYE.
3. What is an FPS?
An FPS, or Full Payment Submission, is the main RTI report sent to HMRC to report employee payments and deductions. It is normally sent on or before payday.
4. What is an EPS?
An EPS, or Employer Payment Summary, is used in specific situations, such as reporting no payments in a tax month or reporting certain adjustments and claims.
5. When do I pay PAYE to HMRC?
The deadline depends on how you pay and your PAYE arrangement. HMRC generally requires electronic payments by the 22nd after the end of the relevant tax month, while quarterly arrangements may apply for eligible employers.
6. Why am I on emergency tax?
A temporary or non-cumulative tax basis can apply when HMRC does not yet have enough information to issue the correct cumulative tax code. W1, M1 and X indicators are commonly associated with this basis.
7. Can payroll software automate PAYE?
Payroll software can automate calculations, statutory deductions, payroll records and reporting workflows. Employers still remain responsible for maintaining accurate information and meeting their PAYE obligations.
