UK Day Rate & Freelance FAQ
Everything you need to know about setting your day rate, managing taxes, and navigating IR35 as a UK contractor.
To calculate your day rate, first determine your target annual take-home pay. Add your estimated annual taxes (Income Tax and National Insurance) and total business expenses to find your required gross turnover. Finally, divide this gross turnover by your expected billable days per year to find your minimum daily rate.
A standard working year in the UK has about 260 weekdays. After deducting 28 days for statutory holiday (including bank holidays), 5 to 10 days for sickness, and roughly 10 to 15 days for non-billable admin or bench time, most freelancers aim for between 210 and 230 billable days per year.
Yes, significantly. If you are caught ‘inside IR35’, you must pay employee-level Income Tax and National Insurance on your deemed employment income, which drastically reduces your net take-home pay compared to being ‘outside IR35’. Contractors inside IR35 typically need to charge a higher day rate (often 20-30% more) to maintain the same net income.
Yes, absolutely. Unlike permanent employees, freelancers do not get paid for time off. Your day rate must be high enough that the income generated from your ‘billable days’ covers your living expenses and tax obligations for the entire year, including the weeks you take off for holidays or illness.
You only need to register for VAT if your taxable turnover exceeds the UK threshold (currently £90,000 per year). If you are VAT registered, your quoted day rate should ideally be exclusive of VAT, meaning you add 20% VAT on top of your invoice for standard-rated clients. If you are not registered, your day rate is your final charge.
