Freelancers are typically self-employed sole traders, which means they pay income tax and Class 4 NI through Self Assessment on their taxable profit after expenses. The day rate mode makes it easy to start from a contract rate rather than having to pre-calculate annual profit.
If you charge a mix of day rates and project fees, use the annual mode and enter expected profit after estimated expenses. The set-aside figure gives you a monthly target for the tax reserve regardless of how income arrives.

From 6 April 2026, Making Tax Digital for Income Tax is mandatory for sole traders and landlords with qualifying income over £50,000. That means keeping digital records and sending HMRC a short update every quarter through recognised software, instead of one Self Assessment at year end. The threshold drops to £30,000 in April 2027 and £20,000 in April 2028, and HMRC reckons around 860,000 people are in the first wave.
HMRC-recognised software includes FreeAgent, Xero, QuickBooks, Sage and Zoho Books. FreeAgent is free for Mettle and NatWest business banking customers. There are no penalties for late quarterly updates during 2026/27.
Keeping a separate account for business income and expenses makes Self Assessment and record-keeping considerably easier.
