Get help with Self Assessment by using online tools and guidance, and watching HMRC YouTube videos.

Getting help from HMRC online is often quicker and easier than calling us.

Use online tools

Help filling in your tax return

There is help text throughout the online tax return that gives information on completing each section. If you complete a paper tax return, you will receive guidance notes that also provide help and information.

You can also find guidance to help you understand and fill in sections of your Self Assessment tax return (https://www.gov.uk/government/collections/get-help-filling-in-your-self-assessment-tax-return). Guidance includes:
- YouTube videos and playlists
- Self Assessment helpsheets
- recorded webinars
Watch YouTube videos and webinars

Use HMRC email updates, videos and webinars for Self Assessment (https://www.gov.uk/guidance/help-and-support-for-self-assessment) to:
- find YouTube playlists to help you get started with Self Assessment, fill in your tax return and understand your tax bill
- watch videos on different areas of Self Assessment
- register for and join live webinars, ask a question in the chat and get answers from one of our experts
Tell HMRC you do not need to send a tax return

You must tell HMRC if you believe you no longer need to send a tax return (https://www.gov.uk/self-assessment-tax-returns/no-longer-need-to-send-a-tax-return).

This might be because you’ve stopped being self-employed or you no longer need to be registered for Self Assessment.

After you have applied to stop Self Assessment, your personal tax account (https://www.gov.uk/personal-tax-account) will show the date and status of your application.

Ask for help online

You can use HMRC’s digital assistant (https://www.tax.service.gov.uk/ask-hmrc/chat/self-assessment) to ask questions about Self Assessment.

You can also ask generic questions about Self Assessment using HMRC Customer Support on X (Twitter) (https://www.x.com/hmrccustomers) — do not include personal or financial information in your post.

Use your HMRC online account

You can sign in to your personal tax account (https://www.gov.uk/personal-tax-account) or business tax account (https://www.gov.uk/guidance/sign-in-to-your-hmrc-business-tax-account) to:
- complete or amend your tax return
- check how much Self Assessment tax you owe
- make a payment or claim a refund
- find your Unique Taxpayer Reference (UTR) for Self Assessment
You can also download the HMRC app (https://www.gov.uk/guidance/download-the-hmrc-app) onto a mobile device (for example, your phone or tablet).

Get extra support

If a health condition or personal circumstances makes it difficult to use our online services, you can find out how to get help from HMRC if you need extra support (https://www.gov.uk/get-help-hmrc-extra-support).

HMRC provides funding to voluntary and community sector organisations so they can help you if you need extra support with your tax. You can contact a voluntary or community sector organisation (https://www.gov.uk/guidance/voluntary-and-community-sector-organisations-who-can-give-you-extra-support) for free Self Assessment help and advice.
