The Nassau Interim Finance Authority said Thursday that Nassau County officials have failed to close a 2011 budget gap and expressed concern the 2012 budget deficit could grow to $225 million.
The six-member panel, which declared a fiscal emergency earlier this year, wants a revised budget by July 28.
NIFA member George Marlin said county officials have "exhibited delusions of fiscal balance."
Deputy County Executive Timothy Sullivan disputed that officials had taken little action to close the gap, noting that nearly 130 county workers were laid off last month.
Residents of the county, outside New York City, pay some of the highest taxes in the country.
