Getting started as self-employed means telling HMRC you’ve begun trading, keeping a record of what comes in and goes out, and filing a Self Assessment return once a year. None of that is complicated on its own, but the deadlines follow the tax year rather than the date you began.
Keeping tax simple comes down to a handful of small habits done at the right time, including registering on schedule, separating business money from personal money and setting a share of each payment aside for the bill. Each one is easy to start in the first month and harder to catch up on later, so they’re worth setting up early.
Registering With HMRC
Someone who starts trading in February has until 5 October of that same year to register, while someone who starts in May has until 5 October of the following year, because the deadline follows the tax year, which runs from 6 April to 5 April. Gross income of £1,000 or less usually doesn’t need to be reported. Above that level, the £1,000 trading allowance can stand in for expense tracking if your costs are low, although it can’t be combined with claiming actual costs on the same income. The online return and payment are due by 31 January after the tax year ends.
Allowances and Fee Income
Some roles pay in allowances or fees instead of wages, and the tax treatment can differ from ordinary self-employment. Foster carers declare their fostering allowance on a Self Assessment return because HMRC treats them as self-employed, and qualifying care relief often means the allowance is completely tax-free, so many carers owe no tax while still filing the return each year. Anyone paid in fees for tutoring, driving or event work should likewise check whether a specific relief or rule applies before assuming the standard approach is the only one.
Keeping Records Through the Year
Records: Keep every invoice, receipt and bank statement linked to the business, and note what each one was for while you still remember. Records need to be kept for at least five years after the filing deadline, so a labelled folder or a simple spreadsheet saves a great deal of time compared with sorting through a shoebox every January. Photograph paper receipts as they arrive, because thermal receipts fade over time.
Separate account: A bank account used only for the business isn’t a legal requirement for sole traders, but it makes income and spending easy to see, and it means you won’t need to pick business payments out of a personal statement when the return is due. Some accounts can be linked to bookkeeping software, which does most of the sorting and makes the yearly return quicker to complete.
Tax money: Employees have tax taken before pay arrives, so the self-employed need their own system. The most reliable way to cover the bill is setting money aside each month as income arrives, and moving a fixed share of every payment into a separate savings account makes the January payment easier to meet. Ask an accountant or check HMRC’s guidance for a sensible percentage, then start transferring from your first invoice.
