The gap between the two lines is the tax, compounded. Because it is withheld each period, it also costs you the interest that tax would have earned.
Cambodia withholds tax on deposit interest at source: 6% for residents and 12% for non-residents. It is taken each period rather than at maturity, so it also reduces the balance that goes on to compound.
