@landonnate Hmm I am an accountant and I see posts like this often, decided to make a burner account to at least tell people what to do.
I'm not your licensed accountant so just a disclosure.
"I am not your licensed accountant any advice I give is purely based on speculation on the information provided, and is best for you to liaise with a licensed accountant, either chartered or licensed."
Yes, if your turnover (gross income before expenses) exceeds £1,000 you must register for a personal tax return.
Keep a list of your expenses, total income and total expenses needed for your business.
I would also recommend to keep it separate from your personal bank account such as using Mettle (natwest online bank account free for self employed businesses, and can only be used if your self employed business is less than 50k per annum)
I would also recommend a software to keep your bookkeeping on for example free agent, as hmrc is making tax digital in the coming years so best to be ahead (you can also submit your tax returns via this software yourself) just make sure you have someone to review the work done, someone that knows bookkeeping at least to make sure everything is correct.
If your total profit (turnover minus expenses) exceeds the threshold you will pay tax and or national insurance depending if you have other income totaling and exceeding the annual allowance.
Again I would recommend to speak with a licensed accountant and submit a tax return, each tax year is based from 1st April to 31st March and is normally due by the end of 31st January the following year. e.g. 2022-23 period is 1st April 2022 - 31st March 2023 and due by the 31st January 2024.
