Surtax is an income tax to the state and is calculated on personal income. In other words, it is calculated on gross income from employment and pensions above a certain amount. You must pay surtax on your personal income in respect of the proportion of your income that exceeds an annual fixed tax-free amount.
From the income year 2016 the surtax is replaced by bracket tax. For the tax return you are doing right now (for the income year 2015), the surtax rules still apply.
