Combined Employer Return

About the new Combined Employer Return

The new Combined Employer Return (CER) will allow you to file your tax, social security, manpower and benefit in kind on one return.

Filing dates and frequency of returns

The filing dates and payment deadlines are being aligned so that the returns can be combined and filed at the same time.

From 2022 the filing dates will be:

Sole traders that don't have any employees will continue to be surveyed on a 6 monthly basis for their manpower information and won't need to complete a combined employer return.

Switch over date: January 2022

The switchover will happen for the January 2022 return due by 15th February 2022. No 2022 or later returns can be accepted in any of the old formats.

Submitting a 2022 return for the first time

When you first log in to submit a 2022 return you'll be re-directed to a new log in page where you will need to request access to Revenue Jersey employer services. Once your account has been activated you'll be able to submit your return. 

Returns relating to 2021 and earlier 

If you need to send in or correct any returns relating to 2021 or earlier you will still need to use the method by which they were originally sent.  For example using the old returns application software or EMPWeb portal.

How to submit your return

There are 3 ways to submit your return online.

Enter your employees information using Revenue Jersey's online form

This is suitable for small businesses with relatively small numbers of employees (40 or fewer).

You can enter more employees (for example you may have seasonal variations), but if you have too many records the system may slow down.

If you regularly employ more than 40 people we recommend that you use payroll software to send your return in.

How it works

One you are logged in, you input employee earnings, contributions data and manpower information directly into our form to submit your return.

As the information is entered, key elements such as your employees Tax Identification Number (TIN) and Social Security Number (SSN) will be checked and matched against the records held in the system. 

You won't be able to submit data where the TIN or SSN are missing or do not match the information held in the Revenue Jersey systems. It is essential that you have the correct information for all of your employees, to aid the smooth running of this process.

Upload an XML file using the online portal

You can submit your employees’ information using a file in XML format, which can be produced by a payroll system and then uploaded manually using the online portal.

How it works

As the file is uploaded it will undertake a two-stage validation process.

Stage one:

  • the XML will be checked to make sure it’s in a valid format and any mandatory elements are correctly included in the file
  • if any errors are found, these will be displayed, the whole file will be rejected and it won’t be processed
  • you will need to correct any errors before the file can be uploaded again

Stage two:

  • employee Tax Identification Numbers (TIN) and Social Security Numbers (SSN) will be matched against the records held in the system
  • if any mismatches are found, the errors will be reported, the whole file will be rejected and it won’t be processed
  • you will need to correct any errors before the file can be uploaded again

Send a file directly from a payroll system 

The sending of the CER is automated by allowing the payroll system to submit a file directly to the Revenue Management System (RMS).

How it works

The payroll system will establish a connection to a file upload portal and transfer the XML file directly to RMS. As the file is uploaded it will undertake a two-stage validation process.

Stage one:

  • the XML will be checked to make sure it’s in a valid format and any mandatory elements are correctly included in the file
  • if any errors are found, these will be displayed, the whole file will be rejected and it won’t be processed
  • you will need to correct any errors before the file can be uploaded again

Stage two:

  • employee Tax Identification Numbers (TIN) and Social Security Numbers (SSN) will be matched against the records held in the system
  • if any mismatches are found, the errors will be reported, the whole file will be rejected and it won’t be processed
  • you will need to correct any errors before the file can be uploaded again

Submitting your return using paper

A paper return is only suitable if you just have one or two employees. If you regularly employ more than 2 people we recommend that you register for Revenue Jersey online services and file your employer return online.

Paper returns will also become a combined return and you will enter tax, social security and manpower information on one monthly form. 

Data accuracy

With all methods, your data will have to be accurate in order for your submission to be processed. Your employees information is validated using both the Tax Identification Number and the Social Security number.

If the data in your submission has any wrong TINs or Social security numbers, this will result in the file failing submission.

If it fails you will get an error report and the return will not be accepted until it is corrected. 

Revenue Jersey will no longer correct returns that contain errors.

Correct errors in your data before January 2022

The majority of employer's submit accurate information, but if you are one of the small number with inaccuracies, it's essential that you plan and take whatever steps you need to, so you can submit accurate and complete data by the date of the switchover.

Changing from Tax Reference Numbers to Tax Identification Numbers (TINs)

Jersey's transition to TINs will continue with the introduction of the new CER, because it will use the TIN rather than the Tax Reference Number.

The effective rate notices we issue to your employees will start including the TIN when we send out the 2022 rate notices later this year.

We are also consulting with a group of employers to see if we can assist with this process of including TINs on your records.

What to do to prepare

Make sure your data is accurate and complete

If you are unsure whether the Registration card held for any employee is up to date, for example as a result of marriage or separation, please advise the employee to check and if needed, contact Revenue Jersey and CLS to update their details and request a new Registration card.

Replace the old tax reference with the TIN on your payroll systems

There may be actions Revenue Jersey can take to assist employers with this, but it may be that employers must or prefer to collect this data directly from their employees. We will update this section on the outcome of discussions with employers in May 2021.

Make sure your Payroll software updates are ready

If you use a payroll software to upload or stream an XML file to our online portal to submit your return, you will need to ensure changes are made to the software so that the file you start using from January 2022 contains the new information required.

If you have been sent a link to the new file specification, you have all you need to get started. If you don't have the new specification you can request the link by emailing cer@gov.je and we will ensure you receive communications about updates to the specifications.

If you have a specialised software supplier who provides and updates your software for you each year, they should be making the changes needed in the coming months.

The changes needed to software systems were communicated in February 2020 and latest file specifications are now available.

Changes to software systems February 2020 communication

Move from paper to online services

If you currently use paper to submit your employer returns, consider moving to online services. The combined employer paper return will only be suitable if you have a maximum of two employees.

Once you are registered for online services you will have a record of your submissions for any future returns and it will be quicker and easier to complete.

Contact us at cer@gov.je and we will help you register for online services.

Why the form is changing

For many employers the new return will eliminate significant duplication of information requests across the currently separate returns, bringing opportunities to cut down on administration.

We’re committed to modernising our legislation, providing easier access to services online, ensuring all customers can understand and meet their obligations, and to reducing assessing and collection costs, which the CER form will help us with.

Moving management of Employer data into our new Revenue Management System will allow us to process your data and allocate payments for your employees far more quickly and efficiently. It also allows us to increase our compliance activities, guiding companies who are making mistakes on what's required.

To allow sufficient time for employers to prepare their payroll systems to work with the Revenue Management System (RMS), the new Combined Employer Return (CER) process was announced in 2018.

The latest version of the specifications was made available in December 2020.
