What's the deadline to register as self-employed?
Every self-employed person needs to let the Government know. The deadline to register and request your Unique Taxpayer Reference (UTR) with HMRC is October 5th of the tax year after you started self-employment.
So, if you started working for Deliveroo, say, in October 2018 or February 2019, you must register as self-employed and apply for your Unique Taxpayer Reference (UTR) number by this October 5th. If you do not register in time you will face a fine.
