PAYE (Pay As You Earn) is the system that HM Revenue & Customs (HMRC) uses to collect Income Tax and National Insurance contributions (NICs) from employees' pay as they earn it. The term 'employee' in this guide includes directors of limited companies.
As an employer, you'll have to deduct tax and NICs from your employees' pay each pay period and pay Employer's Class 1 NICs if they earn above a certain threshold. You pay these amounts to HMRC monthly or quarterly. If you don't send the correct amount, or if you send it in late, you may have to pay interest. After the end of the tax year you must send HMRC an Employer Annual Return (form P35 and forms P14). Almost all employers are required to file this online.
This guide gives a basic overview of what you need to do to operate PAYE including which forms you'll need and key dates. It also provides links to detailed guidance.

As an employer you have a legal obligation to operate PAYE on the payments you make to your employees if their earnings reach the National Insurance Lower Earnings Limit (LEL). For the tax year 2011-12 this is £102 a week, £442 a month or £5,304 a year.
You use the employee's tax code and National Insurance category letter to work out how much Income Tax and NICs to deduct from their pay and how much Employer's Class 1 NICs you owe on their earnings. By the 19th of each month - or by the 22nd if you make electronic payments - HMRC must have received the amounts owed. You may be able to send the amounts due every quarter if your average monthly payments are likely to be less than £1,500.
PAYE is applied to all the payments that an employee receives as a result of working for you, including:
Rates and thresholds for employers
Different tax and NICs procedures apply to expenses and benefits - such as company cars or medical insurance - that you provide to your employees. In certain cases you'll have to operate PAYE on the value of an expense or benefit in the same way as for the various payment types listed above. But more typically you'll need to report the expenses or benefits you've provided to HMRC at the end of the tax year and make a one-off payment of Class 1A NICs on the value of some of them.
Expenses and benefits - more detail
As well as deducting Income Tax and NICs from your employees' pay each pay period, you might also use the PAYE system to deduct other items such as:
You'll have to give each of your employees a pay statement - or payslip - at or before the time that you pay them. This can be in either paper or electronic format but it must show certain items, including each employee's gross pay (before any deductions are made), all deductions and the purposes for which they are made, and the net amount payable after the deductions have been made (also known as take home pay). If you don't give your employees an itemised payslip they could complain to an employment tribunal.
At the end of each tax year you must give them a summary of their pay and deductions on a form P60. You must do this for each employee who was working for you at 5 April whose earnings reached the National Insurance Lower Earnings Limit during the tax year. This must be in paper format and must be given to the employee before 1 June following the end of the tax year.
Pay and deductions: the basics
After the end of the tax year - and by no later than 19 May - you must send HMRC an Employer Annual Return (P35 and P14s) summarising your payroll figures for the year. Almost all employers are required to file this return online.
When you pay your employee for the first time you must check whether you need to operate PAYE and register as an employer with HMRC. Once you have registered, you will receive a letter containing your Employer PAYE reference and a link to the appropriate guidance where everything you need to get started can be accessed. If you employ domestic staff in your home you may be able to operate the Simplified PAYE Deduction Scheme. If you think this may apply to you, read our related guide before you register - follow the link below.
You can register as an employer either online or by calling the New Employer Helpline.

When you operate PAYE you'll use certain key forms and procedures to keep a record of all the payments you make to your employees. Some forms give you the information you'll need to operate PAYE correctly and you'll use others to tell HMRC about your employees and their pay details.
Almost all employers must file forms P45 and P46 online. For details, follow the link below.

You can submit many PAYE forms over the internet once you've registered with HMRC's 'PAYE Online for employers' service. Sending information online is quick and easy and it's more reliable and efficient than using paper forms.
Taking care to make sure your send HMRC the correct information about your employees will save you time by reducing the number of employee queries you get, as well as helping to make sure that your employees pay the correct tax and NICs.
Over 80 per cent of problems are caused because the wrong information is held about an employee's name, date of birth or National Insurance number.
Name - Make sure that you use the full name and not just the initial(s). Ensure that the forename(s) and surname are correctly spelled and that they are in the right order.
Date of birth - Always use the correct date of birth. Do not use a default date or make one up.
National Insurance number - Always use the correct National Insurance number. Do not make a number up or use someone else's.
Wherever possible, check the information with a trusted official source such as a birth certificate or passport.
