Explore invoicesCan I use QuikTax for free?
Yes. Income, expenses, receipt scanning, mileage tracking and tax estimates are available without a Pro subscription. Invoices, reports and CSV exports are Pro features.
Is QuikTax a website or an iPhone app?
QuikTax is an iPhone app. This website helps you explore the product and try a planning calculator. It is not a web bookkeeping dashboard.
Are tax estimates the same as my HMRC balance?
No. Estimates depend on the information you enter and the supported rules. Your HMRC account can also include payments on account, earlier balances and adjustments. Check your actual position with HMRC or your accountant.
Can I use it alongside my PAYE job?
The web calculator lets you include taxable employment income and actual PAYE income tax deducted. It separates the extra tax on business profit from the overall Self Assessment estimate. Employee National Insurance is not PAYE income tax.
