    Why use the ZPP-DOH calculator?

    Manual allocation of allowances is often not optimal. Our calculator uses a mathematical model that guarantees the lowest total household tax.

    Mathematically optimal

    The algorithm evaluates all critical points and finds the globally optimal allocation of allowances.

    For the whole household

    It considers the income, age and disability of both parents to minimize total tax.

    Tax savings

    Allocating children and dependants correctly can significantly reduce the household's total tax.
