Check the following to resolve error 1046
Sending Submisisons to the Wrong Service
On the 14th February 2018 HMRC changed the web address (URL) you use to send your RTI submissions. If you are getting the 1046 Authentication Failure error OR a 501 Not Found error on or after the 14th February 2018, first check the version of your software.
The URL address changes were implemented in our software in the following versions:
- PAYE-Master: v184.108.40.206
- GP Payroll: v2017.1.28
- Business/Bureau: v2.18.119
- IPP/Earnie: v1.26.58
- EarnieIQ: v1.28.0 - Patch C
If you are using a version earlier than those listed above, please update your software and try the submission again.
Otherwise, if you are already using a version higher than listed above, continue to the steps below to resolve the error.
When filing online using your IRIS Payroll product your Gateway User ID, Password and PAYE-Reference (tax district and reference number) are checked against the records held on the HMRC systems. If one or more of these do not match you will receive an Error 1046.
Incorrect User ID & Password
This is the most common reason for receiving an Error 1046. A good way to check the user ID and password is to go to the HMRC login website and try to log in by copying and pasting the User ID and password.
When entering the password into the HMRC website, only the first 12 digits are accepted. When entering them into the software it recognises all digits so would deem anything after the first 12 as being incorrect causing the Error 1046. If your password is longer than 12 digits, only use the first 12 within the payroll software.
If you are unable to log in to the online services website please call the HMRC Online Services Helpdesk on 0300 200 3600.
Please note : A security feature employed by HMRC means if you enter the wrong User ID or password three times or more when trying to log on to the HMRC website, your account will be locked and you won't be able to use HMRC Online Services for the next two hours. You will be able to try again after the 2 hour period has expired.
Incorrect PAYE-Reference (If you are filing for your own company)
Log on to the HMRC website using your User ID and Password.
Click on "Your Services"
Check the companies "Tax District" and "Reference" are registered and activated for you to file RTI submissions online.
The Tax District field should contain 3 numbers (example : 123). The Tax Reference field should contain the other details (example : AB45678). You should not enter a forward slash in to the fields. This will cause the submission to fail.
Incorrect District Name
We have had instances of the submission failing due to an incorrect tax district name.
Check the district name with HMRC to make sure the correct details are used in your payroll software.
Not Registered / activated for the service
Not registered for the service
If PAYE for Employers is not listed under "Your Services" you will need to register for this before you are able to file online.
Not activated for the service
After registering for a service you should receive an activation code. The activation code will be issued within seven days - use it once then throw it away. It will expire if you don't use it within 28 days of the date on the letter, you will have to request a new one.
You will not be able to file online unless you have registered for PAYE for Employers and activated this service.
Agent not registered the PAYE reference of the company
For an agent to submit RTI returns and receive PAYE message from HMRC on behalf of a client the agent needs to be authorised by either:
• Completing paper form FBI 2- this will only give you authority to act for your clients online
• Online authorisation process - which will allow HMRC to deal with you online, by phone or in writing about each of your clients’ PAYE or CISmatters
To submit an online authorisation request for your client you’ll need:
• To have registered for HMRC Online Services and enrolled for the PAYE/CIS for Agents service
• Your client’s employer PAYE reference and Accounts Office reference
• The authorisation code HMRC will send to your client by post - the code with ‘PE’ for PAYE and ‘CS’ for CIS
Please note: the authorisation code can take up to 7 days to arrive. You will need to enter the code before the client appears on your client list, so ideally you need to do this well in advance of a filing deadline. You must enter the code within 30 days from the date on the letter, otherwise it will expire.
