Going freelance is one of the biggest career moves you can make. You choose your clients, your hours and, for many people, a working environment where you can simply be yourself. What nobody puts in the job advert is the paperwork. Once you’re self-employed in the UK, you’re also your own payroll department, and HMRC expects you to act like one.<\/p>\n
The good news is that the first year is far less scary once you know the handful of dates and habits that matter. Here’s the survival guide we wish every new freelancer, contractor and side-hustler had on day one.<\/p>\n
You need to register for Self Assessment by 5 October<\/strong> after the end of the tax year in which you started working for yourself. The UK tax year runs from 6 April to 5 April, so if you went freelance in June 2026, your deadline to register is 5 October 2027. Registering early costs nothing and means your Unique Taxpayer Reference (UTR) arrives well before you need it.<\/p>\n If your self-employed income in a tax year is \u00a31,000 or less, the trading allowance<\/strong> may mean you don’t need to register at all. Above that, you almost certainly do.<\/p>\n Miss the January deadline and there’s an automatic \u00a3100 penalty, even if you owe no tax at all. More follows the longer it runs.<\/p>\n Your first tax bill is often bigger than people expect. If you owe more than \u00a31,000, HMRC usually asks for that year’s tax plus<\/em> half of next year’s bill in advance, with the other half due in July. A good rule of thumb is to move 25\u201330% of every invoice you’re paid into a separate savings pot, so January is a formality rather than a crisis.<\/p>\n You don’t legally need a business bank account as a sole trader, but having one is the single best habit you can build. When every client payment and every business cost runs through one account, your bank statements become your bookkeeping. Mixing work and personal spending in one account means hours of highlighting at the end of the year, and it’s easy to miss expenses you could have claimed.<\/p>\n Allowable expenses reduce your profit, and so your tax. Common ones for freelancers include:<\/p>\n On your return, these go into the headings on the self-employment pages (form SA103), such as “office, property and equipment” or “travel costs”. Getting them into those headings during the year saves a lot of guesswork in January.<\/p>\n HMRC expects you to keep records of your income and expenses for at least five years after the 31 January deadline for that year. In practice, that means invoices you’ve sent, receipts for what you’ve spent, and your bank statements.<\/p>\n Bank statements are where most people get stuck. Many banks only give you a PDF, and copying a year of transactions into a spreadsheet by hand is slow and easy to get wrong. A tool like Bank Statement Convert<\/a> can turn PDF bank statements into an Excel spreadsheet, checks the result against the balances printed on the statement, and suggests which Self Assessment heading each transaction belongs under. Whatever method you use, do it monthly. Ten minutes a month beats a lost weekend every January.<\/p>\n Making Tax Digital for Income Tax is now here. Since April 2026, sole traders and landlords with qualifying income over \u00a350,000 have had to keep digital records and send HMRC quarterly updates using compatible software. The threshold drops to \u00a330,000 from April 2027 and \u00a320,000 from April 2028. Even if you’re below it today, keeping your records digitally from the start means the switch will be painless when it reaches you.<\/p>\n Employees have National Insurance taken from their pay. As a sole trader you pay Class 4 contributions through your tax return, based on your profits. Class 2 contributions are no longer compulsory, but if your profits are low you may want to pay them voluntarily to protect your State Pension record. It’s worth checking your National Insurance record on the government website once a year.<\/p>\n Plenty of freelancers do their own Self Assessment, and HMRC’s online service is reasonably friendly. But an accountant is worth every penny if your income is growing fast, you’re weighing up whether to set up a limited company, you’re also renting out property, or you simply want someone to check your first return. Good accountants often save more than they cost.<\/p>\n Register on time, separate your money, save for the tax bill as you go and keep your records tidy every month. Do those four things and freelance life gets to be about the work you chose, not the admin you didn’t. And if you’re still deciding whether to take the leap, browse the latest roles on Pink Jobs<\/a>: plenty of employers hire freelancers and contractors too.<\/p>\n","protected":false},"excerpt":{"rendered":" Going freelance is one of the biggest career moves you can make.
