How do I register for Self Assessment?

If you’re filing a Self Assessment tax return for the first time, you must register with HMRC. The registration process depends on your circumstances:

Self-employed or sole trader: Register using form CWF1.
Not self-employed: Register using form SA1.
Partner in a partnership: Register using form SA401.

After registering, HMRC will issue you a Unique Taxpayer Reference (UTR) number, which you’ll need to file your tax return.
