There is no signup and you can generate unlimited vouchers whenever you declare a dividend.

Freelancer Tax Health ScoreYour freelancer tax health score is a fast way to see whether your self-employment finances are genuinely under control, or quietly heading for a January scramble. Rather than guessing, the tool above scores how ready you are across the things HMRC actually cares about: being registered, keeping records, putting money aside, and hitting deadlines. It is built for UK sole traders, side-hustlers and freelancers who file a Self Assessment return and want a plain checklist of what to fix next.
IR35 Status CheckerThis IR35 calculator helps you check whether a contract is likely to fall inside or outside IR35 (the off-payroll working rules) by walking through the working practices HMRC actually looks at. It is built for UK limited-company contractors, freelancers and the clients who engage them, and gives you a plain-English read on your status before money or deadlines are on the line. IR35 decides whether HMRC treats you as genuinely in business on your own account, or as a "disguised employee" who should be taxed almost like an employee. Get it wrong and the bill, plus interest and penalties, can be severe.
Late Payment Interest CalculatorThis late payment interest calculator works out the statutory interest you are legally entitled to charge on an overdue business invoice under the Late Payment of Commercial Debts Act. Enter the invoice amount and the dates to get the interest owed plus the fixed compensation you can add on top. Statutory interest runs at 8% above the Bank of England base rate, and you can also claim between £40 and £100 in compensation per invoice depending on its size. The calculator applies the current base rate and shows the daily interest so you can watch it grow until you are paid.
Limited Company Tax CalculatorUse our free Limited Company Tax Calculator to get an instant estimate for the 2026/27 tax year.
MTD Income Tax Scope CheckerThis Making Tax Digital scope checker tells you, in seconds, whether MTD for Income Tax applies to you and from which tax year, based on your self-employment and property income. Rather than wading through HMRC guidance, simply enter your figures and let the tool do the work. Making Tax Digital for Income Tax is being phased in from April 2026, 2027 and 2028 depending on your total qualifying income, so knowing exactly when you are caught helps you prepare for digital record-keeping and quarterly updates well ahead of your start date.

Log your income and expenses as they happen and the organiser groups everything into the four quarterly periods you need to report to HMRC.

Your data saves in your browser, so you can keep your books tidy throughout the year and stay ready for each submission deadline.

Markup CalculatorThis markup calculator turns a cost price and a markup percentage into a selling price, the cash profit you keep and the profit margin behind it. Type in what an item costs you and the markup you want to add, and it does the arithmetic so you can price with confidence. It is built for UK sole traders, shop owners, makers, tradespeople and anyone quoting jobs who needs a quick, reliable price without second-guessing the maths or confusing markup with margin.
Mileage Tracker & ClaimThis mileage tracker turns your business journeys into a tax-free claim using HMRC's Approved Mileage Allowance Payment (AMAP) rates of 45p and 25p a mile. Log your miles, pick your vehicle, and see exactly what you can deduct from your profits or reclaim from your employer. It's built for sole traders, freelancers, contractors, landlords and employees who drive their own car, van, motorbike or bike for work. Whether you're filing a Self Assessment return or claiming mileage allowance relief through PAYE, the maths is the same - and most people undercount.
P11D GeneratorOur free P11D generator creates a clear PDF listing an employee's taxable benefits in kind and the total cash equivalent, plus the employer Class 1A NIC.
