Project Description:
I need an app that can calculate the amount of tax that must be paid on interest earned in a savings account. The amount of tax depends on the amount of income that the user earns over the 2013 personal allowance of £8105. For example, if a user earns between £2790 and £32010 above the personal allowance they'll need to pay 20% tax on any interest earned. This categorises the user as a basic rate tax payer. So £10000 at 4% for a basic rate tax payer over one year would mean that they earn £320 of net interest, paying £80 in tax.

Higher rate tax payer -> income (over personal allowance) between £32010 and £150,000 -> Pays 40% tax on interest earned
Additional rate tax payer -> income (over personal allowance) over £150,000 -> Pays 45%
Starting rate tax payer -> income less than £12,230 -> Pay 10%

Please see my picture on how I'd like the app to look.

The ideal freelancer must have an understanding of the maths involved behind the tax calculations, along with the answer to: What would a basic rate tax payer earn (net) from £20000 at an interest rate of 2%.

I need someone who can tell me how to test, and help me publish the app on the Google Play store, and the Amazon Marketplace.

Please feel free to ask any questions.

Sorry i made a mistake, i meant that the starting rate tax payer pays 10% if their income is less than £10895 not £12230 (that's for next year)
