The latest poll found a five point increase in support for the tax.
However, it also found a 20 point difference between those within the eurozone and those outside it.
The poll found 73% of those in the currency bloc supported the tax with strongest support coming from Greece, Cyprus, Italy, Portugal and Spain.
Just over half (53%) backed a financial transaction tax in non-euro countries.
Anni Podimata, European Parliament vice-president and rapporteur on the financial transaction tax, says the levy is “gaining real traction among all Europeans”.
The poll was conducted between March 10-25 and included the opinions of 26,593 Europeans aged 15 or over.
