A CWF1 form is something that you fill out when you’re self-employed. You use it to tell HMRC that you are earning money and need to do a Self Assessment. You can use it both to register or to re-register as a sole trader. Of course, you can also do all this online, but you would use this form if you prefer paper registration.
Self Assessment is the process by which you pay the taxes you owe to HMRC on untaxed income. If you work full-time as an employee, you pay your taxes directly from your salary. This method is called Pay As You Earn (PAYE). But when you’re self-employed, you earn money gross i.e. tax is not deducted from it. This means that you have to declare your earnings to HMRC yourself and do a tax return.
And you nee to do this by 31st January, the year after the tax year you’re paying for.
“Wait, what does that mean?!” you ask. Here’s an example:
You start trading in September 2020. This means you’re earning in the 2020/21 tax year which runs from 6th April 2020 – 5th April 2021. You need to pay your first tax bill by 31st January 2022.
When you fill out a CWF1 form, you have to provide the following details:

After you’ve submitted your CWF1 form, you’ll be given a Unique Taxpayer Reference (UTR) number, which you use to pay your tax return.
If you’re registering with a CWF1 form, the deadline to submit is the same as the online deadline. You must register for Self Assessment by 5th October, no later than the year after you start trading.
