If you sign into your business tax account but can’t find the Self Assessment service, it’s likely to be for one of two reasons:
- You may not have used Self Assessment or sent a tax return online before, so you probably haven’t added Self Assessment to your account. To add this, choose ‘add a tax duty or scheme’ to get started. Then choose the service you want to add – in this case Self Assessment.
- Or, if you have used Self Assessment or sent a tax return online before, you may be using a different account this time. To find out if you have another account where you’ve added Self Assessment choose ‘Check if your Self Assessment is in another account’. It will ask for your Unique Taxpayer Reference (UTR). You can find your UTR on your tax return, statement of account or other Self Assessment calculations. It will check if the UTR has been used for another account. If it hasn’t it will ask you to add the Self Assessment service to this account. If it has you can recover your user ID and password for that account, online. You can then sign in to access and send your Self Assessment.
