Taka is the official currency of the People's Republic of Bangladesh. The Bangladesh Bank is responsible for the issuance of most of the taka banknotes. The taka banknotes were first issued in 1972, following the independence of Bangladesh, replacing the Pakistani Rupee. The Security Printing Corporation (Bangladesh) Ltd. has the sole legal authority of the printing of the banknotes.
There had been eleven series of taka banknotes since the issuance of the first series in 1972. Banknotes generally feature the heritage sites (mostly mosques), national monuments and portrayals of the village life, agriculture, industry and animals of the country. Apart from this, the portrait of Sheikh Mujibur Rahman, the founding president of Bangladesh, used to feature in the obverse of the series issued under the Awami League governments.
Bangladesh introduced its first banknotes on 4 March 1972. At first 1 taka and 100 taka banknotes were introduced. Later 10 and 5 taka notes were added. This first issued series is commonly known as "Map Series". These banknotes are considered as emergency issue banknotes to replace the Pakistan rupee banknotes both with and without rubber stamp overprints.
After issuing the first banknotes, there were many conspiracy theories, counterfeiting problems and rumours, so the government issued the second series. These second series banknotes were printed by Thomas De La Rue of the United Kingdom. First-issued banknotes were subsequently withdrawn from circulation by 30 April 1974 after having ceased to hold legal tender status from 30 March 1974.
Bangladesh Government signed agreements with Thomas De La Rue and Bradbury Wilkinson at the same time. Both of them printed same denominations with different design almost at the same time. As a result, two different series were circulating at the same time.
In 1976, following the assassination of Sheikh Mujibur Rahman and subsequent regime changes in 1975, a completely new series of notes was introduced, with the exception of the 1-taka note, which was released as the second variety of the third issue during 1976. The notes of this issue are notable for the absence of the portrait of Sheikh Mujib, whose portrait had dominated all issues of the Bangladesh Bank until this issue. Instead of the familiar portrait, each note has an illustration of the Star Mosque on its front. 50 and 500 taka denominations were added in this series. 5, 10, 50 and 100 taka denominations were printed by Thomas De La Rue. 500 taka notes were printed by Giesecke and Devrient of Germany.
The fifth issue of banknotes was introduced over a two-year period from December 1977 to September 1979. The notes of this issue are very similar to those of the fourth issue; except the Star Mosque was replaced on most notes by a new vignette and the colours of the notes are a little darker. There was no 500-taka note released in this issue, but a new denomination note of 20 taka was introduced on 20 August 1979, being the last note of this issue prepared by the Bangladesh Bank.
During the 1980s, some designs of taka notes were introduced, but most of the designs were the same. A new denomination of taka 2 note was also introduced. 10 and 50 takas were redesigned. Other denominations were the same as the previous series.
After Awami League formed government in 1996, a newly designed banknotes of 10, 50 and 500 taka were issued from 1997. 10 taka note had a portrait of Sheikh Mujib for the first time since the third series.
This series was printed between 2000 and 2001. A polymer banknote of denomination 10 was added, but later withdrawn due to lack of popularity. Paper notes of denomination 100 and 500 were printed with new designs. A portrait of Sheikh Mujibur Rahman was added on each new note replacing the National Martyrs' Memorial.
After the Bangladesh Nationalist Party (BNP) came to power in 2001, new series of banknotes were introduced between 2002 and 2003. The portrait of Sheikh Mujib was absent in this series. In 2008, 1000 taka note was introduced for the first time.
After Awami League restored power in 2009, the Bangladesh Bank issued a new series of banknotes, phasing out the older designs for new, more secure ones. All banknotes other than the 1 taka feature a portrait of Sheikh Mujibur Rahman on the obverse along with the watermark of the National Martyrs' Memorial.
Following the fall of Awami League in the July Revolution in 2024, the Bangladesh Bank announced plans to redesign Taka banknotes by 2025. The central bank's Currency and Design Advisory Committee, made up of nine members was selected to submit theme proposals to the Ministry of Finance. Sheikh Mujib's portrait was removed and graffiti of the July Revolution was added in this series.
The folder of the banknote for the 40th anniversary of the independence of Bangladesh had a spelling error of the name of the country. It was inserted as Bangldesh instead of Bangladesh.
