How is the tax calculated in Analyser?

Analyser looks at all taxable income that is being received as a gross figure for each tax year. This total is then cross referenced against the relevant tax table (either Scottish or non-Scottish), this then tells the system how much tax to apply to the taxable income. The same process also happens for calculating National Insurance Tax. If the inputs into the system have been specified as monthly amounts then Analyser will calculate the monthly rate of tax to apply so that the tax liability is accurate.  

Once the tax % has been calculated this is applied to the taxable income, then combining this value to the non-taxable income the system is able to produce a Net Income figure, either on a monthly or annual basis.
