This is a tool that calculates the UK income tax and net income for the dividend income segment of the total gross income over a specified tax year, and displays the results in a table.

Additionally, if required, the tool displays more detailed results from the tax calculation: the tax allowances used, the tax band details (showing the range, taxable income, tax percentage rate and calculated tax for each band), and, if relevant, any tax rebate applied.

For these calculations, it is necessary to supply the following compulsory information:

• Your annual dividend amount, which, for flexibility, can either be entered as the annual dividend received or the annual gross dividend income. If you enter the dividend received then, for calculation purposes, this is assumed to make up 90% of the gross dividend income, with the annual dividend tax credit making up the remaining 10%. The dividend received will differ from the calculated net income in the results table, if any of your dividend income falls within the higher rate tax band.
• Your annual savings income, which, for flexibility, can either be entered as a net or gross interest amount. If your bank or building society has already deducted tax at the basic rate (20%) from your savings interest before you receive it, which should be indicated on your statement, you should enter your savings income as a net interest amount. Otherwise, you should enter it as a gross interest amount. This savings income is necessary to know because dividend income is taxed after savings income, and thus the savings income affects which income tax band(s) the dividend income is taxed in.
• Your gross earned income in monthly, weekly or annual terms. This is necessary to know because savings income is taxed after earned income, and thus the earned income affects which income tax band(s) the savings income is taxed in.
• The tax year, noting that this runs from 6 April in the first year to 5 April in the next.
• Your date of birth, in the default format (DD/MM/YYYY), unless you change the format in the menu. To reduce the time needed for data entry, a default date of birth is provided that can be used by most tax payers for calculating tax. Only if you are 65 or over during the tax year, and age related allowances come into consideration, is it essential to provide an accurate birth date.

If you qualify for any of the extra income tax allowances, i.e. additional to the personal allowance, then supply the relevant parts of the following information:

• If you qualify for the blind person's allowance, choose Yes in the drop down box.
• If you are entitled to the married couple's allowance, choose one of the options starting with Yes in the drop down box. If you were married, or became a civil partner, before the start of the tax year, then select Yes - Full to indicate that you are entitled to the full allowance. If you were married, or became a civil partner, during the tax year, you need to work out how many tax months of allowance you are entitled to, and select the appropriate option. To determine the entitlement, begin with the full 12 months and deduct a month for each complete tax month before the date of your marriage or civil partnership.
• The date of birth of your spouse, if your spouse is older, since this may affect your married couple's allowance.
• If you are entitled to the married couple's allowance and wish to apply the tax rebate associated with this allowance to your dividend income tax, choose Yes in the drop down box.
• Note: The calculator assumes that only one member of an entitled couple gets the married couple's allowance. It does not allow for the specification of the transfer of part of the allowance to the other spouse or partner.
