# I get an 'authentication error' when I try to e-file. What should I do?

Authentication errors are usually due to one or more of the following reasons:
- Wrong HMRC User ID entered
- Wrong HMRC Password entered, or the HMRC password was not in lower case
- Not registered for PAYE Online for Employers in the HMRC website
- Wrong Employers PAYE Reference entered.
What you need to do now:



Please click on the link

[https://www.gov.uk/government/organisations/hm-revenue-customs]to go to the
HMRC website. Sign in to your HMRC account using the User ID and Password you
have from the HMRC. If you are unable to sign in to the HMRC website because you
do not have a HMRC User ID and Password, or because the User ID and Password you
have are not working, it means you cannot e-file at this time using those
details. Please call the HMRC. Their phone number can be found on the HMRC
website's Contact Us page. When you are able to sign in to the HMRC website you
should do the following:



1. Check your User ID: Cut and Paste the User ID which you used to successfully
sign in to the HMRC website into our website's Employer / Setup > Chart of Setup
> E-Filing Setup > option No. 2 > Edit section.

2. Check your User Password: Enter the Password which you used to successfully
sign in to the HMRC website into our website's Employer / Setup > Chart of Setup
> E-Filing Setup > option No. 2 > Edit section.
Note: the HMRC Password should be entered completely in lower case.
3. Check your registration for PAYE Online for Employers: After signing in to
the HMRC website check to see if you are registered for PAYE Online for
Employers by clicking on 'PAYE' in the left hand menu. If you are not yet
registered, you should register now by entering the details requested.
4. Check your Employers PAYE Reference: If you are registered with the HMRC for
PAYE Online for Employers, in the left hand menu click on 'About Your
Organisation' . Now cut and paste the PAYE Employer Reference you see in the
HMRC website into our website's Employer / Setup > Chart of Setup > E-Filing
Setup > option No. 2 > Edit section.
After you have completed points 1 to 4 above, re-start the e-filing process in
our website. If the e-filing still fails then try to e-file using our Agent
Credentials. Go to Employer / Setup > Chart of Setup > E-Filing Setup and select
option No. 1. Now try e-filing again.
