Payments on Account CalculatorOur payments on account calculator helps you work out whether you owe Self Assessment payments on account, how much each one is and when they're due. Payments on account are advance contributions towards your next Self Assessment tax bill, spreading the cost so you don't face one large lump sum. Enter your figures to check whether HMRC expects these advance payments from you, plan ahead for each instalment and avoid surprise demands or interest charges when your return is filed.
Payroll CalculatorUse our free Payroll Calculator to get an instant estimate for the 2026/27 tax year.
Profit & Loss StatementThis profit and loss calculator turns your sales, costs and overheads into a clear P&L statement in seconds, showing gross profit, net profit and the margins behind them. It is built for UK sole traders, freelancers and small limited companies who want to know whether the business is actually making money before the accountant confirms it. Enter your figures above, and you get a tidy summary you can sanity-check against your bookkeeping, your bank balance and your tax return. No jargon, no spreadsheet formulas to remember.
Profit Margin CalculatorUse our free Profit Margin Calculator to get an instant estimate.
R&D Tax Credit CalculatorThis R&D tax credit calculator helps UK limited companies estimate the qualifying spend behind a Research & Development claim and the rough cash benefit it could unlock against their corporation tax bill. If you have staff, subcontractors or cloud costs tied to solving a genuine technical problem, you may have a claim and not realise it. It is built for company directors, finance leads and accountants who want a quick, honest sense of scale before committing to the full HMRC paperwork for the 2026/27 accounting period.
Receipt Scanner (OCR)This free receipt scanner app reads a photo or PDF of any UK receipt and pulls out the four things that matter for your books: the supplier, the date, the total and the VAT. Drop in a crumpled lunch receipt, a fuel station printout or a supplier invoice, and the optical character recognition (OCR) does the typing for you. It is built for sole traders, freelancers and small limited companies who need to scan receipts for tax without paying for bookkeeping software. Nothing here is a rate that changes each April, so it works the same in every tax year.
Salary vs Dividend CalculatorUse the dividend vs salary calculator above to compare how much tax you pay taking income as salary versus dividends, and find the most efficient split for a company director in 2026/27.
Side Hustle Tax CalculatorUse the side hustle tax calculator above to work out the tax on income from a side project alongside your main job, and whether the £1,000 trading allowance covers you.
Umbrella Company CalculatorUse our free Umbrella Company Calculator to get an instant estimate for the 2026/27 tax year.
Director's Loan CalculatorIf you take money out of your company beyond your salary, dividends or expenses, it goes on your director's loan account . This calculator works out the S455 tax on an overdrawn loan and the benefit-in-kind cost when the loan is over £10,000.
PAYE vs Self-Employed CalculatorEarning the same money as a salary or as self-employed profit leaves you with different take-home pay - mostly because of National Insurance. This calculator compares both side by side for 2026/27, so you can see the real difference.
