1) A Business Mileage Logger - using the inbuilt GPS functions of your Android device, this tool can accurately track and record the distance you have travelled and produces a file to email to your accountant.
2) Key Tax Dates Reminders - set yourself reminders for when your key tax dates are - never forget a VAT submission or a Payment On Account again!
3) Expenses logger - log your business expenses as you incur them so that you don't forget to submit them to your accounts department!
4) Several tax calculators - from income tax (and net income tax) to stamp duty to corporation tax. Handy little calculators to help you to estimate taxes due.
5) Plenty of tax tables - so that you can look up tax bands for corporation tax, stamp duty, income tax and much more...
IMPORTANT - the Business Mileage Tool requires the use of GPS. Continued use of GPS in the background can dramatically effect battery life.
