Starting the tax year: codes and forms

Before the start of the new tax year, HM Revenue & Customs (HMRC) may send you updates containing new tax codes and tax and National Insurance tables to use from 6 April.

To ensure that your employees pay the right tax from the start of the year you'll need to set up new P11 Deductions Working Sheets (or equivalent payroll records) for them and apply these new updates and codes.

HMRC may send you additional updates after the Budget - you'll normally need to apply these from mid May.

This guide provides an overview of what updates to expect and when and what action you'll need to take.

Setting up new payroll records at the start of the tax year

At the start of the tax year you'll need to set up a new form P11 or equivalent record (either electronic or paper) for every employee who'll be working for you in the coming tax year and for whom any of the following applies:

  • their pay is at or above the National Insurance contributions (NICs) Lower Earnings Limit (£102 a week, £442 a month or £5,304 a year for 2011-12)
  • HMRC has sent you a tax code for this employee
  • you are required to operate a tax code taken from their form P45
  • you have paid your employee and are required to operate tax code BR or 0T in accordance with the P46 procedures

Benefits of using payroll software

HMRC strongly recommends that you keep electronic rather than paper-based payroll records. Using software saves you time, reduces errors and makes it easier to file PAYE forms online - a significant advantage because almost all employers and pension payers are required to file their in-year starter and leaver information and their Employer Annual Return (P35 and P14s) online.

You can keep electronic payroll records using either commercial payroll software (some of which is free) or HMRC's free P11 Calculator. You'll find the P11 Calculator within HMRC's Basic PAYE Tools package - it's very important to make sure you're using the latest version as this will include the most recent PAYE updates from HMRC.

Updates to payroll software and the tax and National Insurance tables

If you use commercial payroll software your supplier should automatically send you updates that incorporate these changes. It's important to make sure you get these software updates.

If you use the interactive P11 Calculator contained within the Basic PAYE Tools package, HMRC will notify you of the required update. Again, it’s important to download this update - the software will do everything for you.

If you use the manual tables, either as a paper or electronic copy, you will need to ensure that you use the correct tables. In January or February HMRC will normally publish new tax and National Insurance tables to use from 6 April - these include any changes that were announced during the last tax year.

If you are continuing to operate a manual payroll there is an alternative to the manual tables. There are some easy to use calculators available to help you to complete your form P11 Deductions Working Sheets(s). You can find a list of all of the payroll tools for employers by following the link below.

All PAYE tools for employers

If you require a paper copy of the tables please help HMRC to save paper and costs by printing off the table you require. The tables are available in an easy print format by following the link below. If you do not have internet access you can order paper copies from HMRC's Employer Orderline.

Receiving new year tax codes from HMRC

Increasingly, HMRC sends tax code notices online to employers. It will start sending them online as soon as you register for its 'PAYE Online for employers' service - which most employers must do in order to meet the requirement to file their in-year starter and leaver information and Employer Annual Return online.

There are two ways of accessing the tax codes that HMRC sends online. You can:

  • Log on to the 'PAYE online for employers' service on the HMRC website and choose the 'tax code notices' option. If you provide the service with an email address, it will send you an email alert each time HMRC sends you an update.
  • Use the PAYE Desktop Viewer (PDV). This is an application that you can download and install from the HMRC website. It is particularly suitable for employers expecting to receive a lot of tax code notices from HMRC.

If you have registered for the 'PAYE Online for Employers' service you can opt out of receiving your tax code notices online, although HMRC would encourage you not to do so.

Applying new tax codes that HMRC sends you

You'll need to update your employees' tax codes before the first pay day of the new tax year. The sections below outline the various forms that HMRC uses to tell you about new tax codes, and explain how to use these codes to make sure your payroll calculations are correct.

Form P9X - generic changes

The form P9X ‘Tax codes to use from 6 April’ gives details of any generic changes to your employees' tax codes. These changes are normally made because new tax rates, thresholds or allowances are coming into effect and will affect the amount of tax you'll need to deduct from your employees' pay from 6 April.

For employees for whom you haven't received a form P9(T) and for whom you don't have an unused P6 (see later sections):

  • carry forward the authorised tax code from their last year's form P11 or equivalent payroll record to their payroll record for the new tax year
  • apply the instructions from form P9X

If you have received a form P9(T) for an employee, or you have an unused P6 for them which arrived too late to use, follow the guidelines in the sections below.

Form P9(T) - individual changes

For some employees HMRC may also send you form P9(T) ‘Notice to employer of employee's tax code’. This shows a revised tax code for the following tax year. You won't get a new individual tax code for every employee - only if individual adjustments are needed to their tax code.

If you get a form P9(T) for an employee, you must:

  • scrap any previous P9(T) for the same employee which has an earlier date
  • keep the most recent P9(T) to update an employee's record
  • use the code shown on the new form from 6 April

Where, exceptionally, you receive a P9(T) or other tax code notification significantly later than the date from which it is to be applied contact your tax office for confirmation of the code to be used.

Employee not issued with a form P9(T) but has an unused form P6

If you received an in-year tax code change for an employee on form P6 but it arrived too late to use it in the last year, carry forward this code instead for the new tax year and follow the P9X instructions.

Applying new tax codes using payroll software or P11 Calculator

Using commercial payroll software or HMRC's P11 Calculator contained within the Basic PAYE Tools package makes dealing with new tax codes quick and simple. You simply enter the new tax code - from form P9(T) or by following the P9X instructions - on to each individual employee's record. Do this after you have finalised the records for the previous tax year.

As long as you're using the updated version of your software or the Basic PAYE Tools package it will automatically work out for you the new tax and NICs you need to deduct from your employee’s pay. There's no need for you to refer to any tax and National Insurance tables. But do make sure you're using the latest version.

Where to get HMRC's free P11 Calculator

A set of Basic PAYE Tools are now available to download straight to your computer. In addition to the P11 Calculator, the tools include:

  • an employer database on which you can record your employees' details
  • a range of other calculators that work out, for example, statutory payments
  • interactive forms such as P11D working sheets
  • a Learning Zone - including interactive material on how to use the Basic PAYE Tools

Download Basic PAYE Tools (Opens new window) from the Business Link website

Applying new tax codes when using the paper form P11

If you’re still using paper methods to maintain your payroll records, you'll need to copy the tax code from form P9(T) into box L on your paper form P11. If you haven't received a P9(T) for the employee, follow the instructions on form P9X instead.

You can then calculate the tax and NICs either with:

  • HMRC's easy to use online calculators
  • tax and NICs tables that you can download or order from the HMRC website - there are 'calculator' tables for use with a hand-held calculator and manual tables

Whether you’re using the tax and NICs tables or calculators, make sure you use the latest version. If you use an outdated version your figures will be wrong.

If you're still keeping paper payroll records it's worth considering switching to electronic methods (commercial payroll software - some of which is free - or HMRC’s free P11 Calculator, as described in the previous section). These work everything out for you automatically and will both save you time and reduce error.

Keeping electronic payroll records also makes it easier for you to file your PAYE forms online. This is a significant advantage over paper-based record keeping as almost all employers and pension payers are required to file their in-year starter and leaver information and their Employer Annual Return (P35 and P14s) online. Read the related guidance below to find out more about filing online.

Implementing changes announced during the tax year

There are sometimes changes to make to your employees' records after the start of the new tax year as a result of the Chancellor's spring Budget statement. If so, HMRC will send you an update on form P7X and will provide any necessary updates to your Basic PAYE Tools. You'll need to follow the instructions on form P7X and apply these changes from the date HMRC informs you of.

For example the changes may include:

  • any Budget-increased tax codes
  • updated versions of the Employer Helpbook E12, ‘PAYE and NICs rates and limits’
  • new Taxable Pay Tables

It's important to destroy any earlier versions of tables and guidance you may have. If you use paper-based methods you can download new versions or get them from the Employer Orderline.
