Agent requesting gov gateway logins

Hello, We're considering using an agent for our tax returns and came across a well reviewed company. Upon talking to them further however they requested our gov gateway logins to proceed. I am aware this isn't allowed but they are insistent that they only operate this way. This is an established firm with several thousand clients and I am concerned they may be abusing their position based off what they said they needed the logins for. Is there any place to report this?

Hi John S,
An agent should not need your log in details for your goverment gateway account.
The procedure should be that they will request agent authority digitally via their Agent account and would therefore never require your log in details.
If you believe they are acting fraudulently then please report them using the following link:
Report tax fraud or avoidance to HMRC
Thank you.

I am a tax agent with many hundreds of clients we do VAT returns for. We never use the clients gateway login details, with a new client we send an email link to client which they click on, this link asks client to log into their own gateway and one logged in, client authorises us to be their agent. It might be that the Accountants you are using want to do this process for you as a convenience, but nothing here that cannot be dealt with by clear communications and explaining to you that you will get a link from the Accountant and click on the lick, etc. There are some things the agent cannot do with their agent access, for example they cannot access postponed import VAT statements, again, client should be instructed on how to login and download the postponed import statements and then send them to the Accountant. Again, the Accountant might be trying to be helpful and convenient by logging into your gateway to download the postponed statements to save you doing it, but if you don't want to give them your logins, then don't, the agents can still do what they need to do, they just need to explain that you may have to download certain things from time to time. It's unlikely fraud, more likely convenience (to the agent) and (minor) convenience for the client, but HMRC are correct that agents should not be asking for login details.
