Banks gave the Island's dormant assets fund almost £5.6 million last year.
The figures are given in the fund's annual report, which is due to be laid before Tynwald when the court sits later this month.
The fund collects cash from bank accounts which have been unused for 15 years, and the proceeds are distributed to good causes via the Manx Lottery Trust.
The 2025 report shows Barclays Bank led the way, transferring £2.5 million, while Royal Bank of Scotland International transferred £1.9 million.
