I have lost my login details
If you've lost your User ID, email Business Tax.
If you can't remember your password, there's a link on the homepage. Select forgotten your password and this will be reset. An email will be sent to the email address used when the company registered online.
Change user account details
To change the name, email address or password of your user account:
- Log in using your User ID and password
- Click on your user account name on the menu bar and select 'Your Account'
If you cannot log in to your account, please write to us confirming the new email address. Include your User ID and make sure it is signed by a person who is authorised to act on behalf of the entity (eg a director of a company, a company secretary, a member of the council of a foundation, an officer or committee member of an unincorporated body, association or co-operative). To speed this process up,
email Business Tax a scanned copy of the letter.
Alternatively, you may wish to register the company again.
Help with filing your corporate return online
It is no longer possible to file your corporate return on paper. The corporate return must be filed online.
If you have difficulties using the online facility you may wish to consider appointing an agent.
If you are unable to use the online facility, you can make use of the online self service area available in Customer and Local Services by calling us on an available phone (next to each computer) by dialling 40300, option 3.
Unfortunately we are unable to offer the use of the online self service area at present due to Covid-19 restrictions.
You will need an email address to be able to register, and the registration process involves an activation pin being sent by post therefore this will take two trips.
You may be required to upload your accounts to the return, currently you will be unable to do this at the online self service area, however we can show you how you can do this when you have an electronic copy of your accounts available.
Please bring all records required to complete the tax return with you, together with your user ID and knowledge of your password.
I've filed the return but made a mistake
You can't go back and edit the return if you've submitted it. Please write or email us with the amended details and this will be kept on file for reference.
Change of ownership
If there's a change of company ownership, you can either ask for the login details from the previous owner or register as a new user.
If you have the login details from the previous owner, you can change the name, email and password associated with that account by clicking on your user account name in the menu bar and then clicking on 'Your account'.
Corporate tax return deadline and fines
A company is required to deliver its return for the year of assessment by midnight on 31 December of the following year.
A company which fails to deliver the return by this deadline will be liable to a penalty of £300. Furthermore if the return is not delivered within 3 months after the deadline will also be liable to an additional penalty of £100 for each month that the return remains undelivered up to a maximum of 9 months.
Foundations, unincorporated bodies, associations and co-operatives
A foundation, unincorporated body, association or co-operative is required to deliver its return online for the year of assessment by midnight on 31 July of the following year.
A foundation, unincorporated body, association or co-operative which fails to deliver the return by this deadline will be liable to a penalty of £300. Furthermore if the return is not delivered within 3 months after the deadline will also be liable to an additional penalty of £50 for each month that the return remains undelivered up to a maximum of 9 months.
Appealing a late return penalty
If you receive a penalty notice you can appeal it in writing within 40 days of the notice date if:
- a failure in the government computer system prevented you from submitting the return
- a serious illness, disability or serious mental health condition has made you incapable of submitting your tax return
- your entity is not required to submit a return
You must make your claim in writing and include:
your name (or your client's name if you're acting on behalf of someone else)
your authorised agent name, address and contact details (if acting on behalf of someone else)
your tax reference number
full details of why you submitted your online return late or why the penalty should not apply
If there was a failure in the government online system, provide the date you tried to file your return and include details (or a copy print out) of the IT system error message.
Each case will be considered on its own merits. You should still always submit your tax return as soon as you can.
