Step-by-Step Guide to Filing Your Self Assessment Online
Step 1: Register for Self Assessment (If You Haven’t Already)
If this is your first time filing, you’ll need to register with HMRC. You can do this online, and the process involves providing your personal details, including your name, address, and National Insurance number. You’ll also be asked to provide the date you became self-employed, if applicable.
Once registered, HMRC will send you your Unique Taxpayer Reference (UTR), which is required for submitting your self assessment online. It typically takes around 10 working days to receive your UTR by post.
Step 2: Set Up an Online Account with HMRC
After receiving your UTR, you’ll need to set up your online account with HMRC. This will allow you to submit your self assessment online and access other services related to your taxes. Be sure to remember your login details, as you’ll need them every year when submitting your return.
Step 3: Choose the Right Tax Return Form
When filing your self assessment online, make sure to select the correct form. The most common forms are:

- SA103: For self-employed people with a sole trader business or freelance income.
