According to the study from MoneySupermarket, 15 per cent of sampled Britons hope to wrack up a total of £11,280 in tax-free savings through an Isa by April.
With two months of the tax year remaining, there is still enough time for the 8.3 per cent of people who said they won't bother to meet their Isa allowance to change their minds.
As the study revealed, a third of people surveyed have yet to make the most of their Isa allowance, even though the interest on a cash Isa is tax-free.
It seems some people need to brush up on their understanding of Isas too, with five per cent of people questioned admitting they are failing to save into an Isa because they simply don't understand them.
Encouragingly, 38 per cent of respondents said they had met the allowance on their cash Isa, while 5.7 per cent have invested in a stocks and shares Isa.
"Isas are not as complicated as they may first seem," said Kevin Mountford, head of banking at MoneySupermarket. "People who are in a position to be able to save at the moment need to do everything in their power to maximise their savings pots."
For a number of Britons, however, savings are out of reach, with 17.3 per cent of cash-strapped people saying they do not have enough left over to invest in an Isa.
The figures coincide with the latest calculations from Wesleyan Assurance Society, which suggest a saver with £5,000 could have lost £418 in gross interest in the past four years as a result of the 0.5 per cent base rate.
Sales and marketing director at Wesleyan Samantha Porter said: "One way to lessen the effect is to make use of individual Isa allowances, shielding some or all of their savings from income tax and thus preventing it from being eroded further still."
