Treasury says more than £1.6 million on unclaimed money's been paid out to charity this year.
It's due to put a report before Tynwald this month about the Dormant Assets Fund.
The fund takes money from Island banks from accounts that haven't been touched for 15 years or more and whose owners can't be found.
The document shows the Manx Lottery Trust was given £1,681,348 in the past 12 months.
