The adópengő bonds and certificates served as money in the last days before the introduction of the Hungarian forint.
The aim was to create a numerical basis for budget calculations, which was independent from the daily changes.
[1] The so-called adójegy (tax bill - a bond for adópengő with two months maturity) was introduced in May 1946.
From 23 June it was also used to pay public utility charges and from 8 July it became a legal tender, replacing the pengő, which almost totally lost its value by this time.
The Hungarian Postal Savings Bank issued adópengő non-interest-bearing savings certificates (nem kamatozó pénztárjegy) in June 1946, which also served as legal tender. ]
